HDR 10 LED DISPLAY

HDR stands for High Dynamic Range, which is a technique of capturing, processing and displaying images that have a much wider range of color and contrast than standard dynamic range (SDR) images. HDR images can show more details in both bright and dark areas, as well as more vivid colors, making them more realistic and closer to what the human eye can perceive. HDR is often used in photography, video games, movies and TV shows to enhance the visual quality and immersion of the content.

SDR VS HDR LED DISPLAY copy

There are several HDR industry standards that define the technical specifications and requirements for HDR content creation and display. Some of the most common ones are:

  • HDR10: This is an open-source HDR standard that is widely supported by most HDR display devices and media platforms. It was announced by the Consumer Technology Association in 2015 and requires a 10-bit color depth, a BT.2020 color space, and a minimum display brightness of 1000 nits.
  • HLG: This is a HDR standard developed by the BBC and NHK for digital program delivery. It was launched in 2015 and does not use metadata, but rather combines HDR signals into TV broadcast signals. It is compatible with current broadcast equipment and has no licensing fees. It is suitable for cable/satellite TV and live broadcast.
  • Dolby Vision: This is a proprietary HDR standard developed by Dolby Laboratories that requires certification and payment. It was launched in 2014 and offers a 12-bit color depth, a BT.2020 color space, and a minimum display brightness of 4000 nits. It also uses dynamic metadata to optimize the HDR image quality for each scene. It is supported by some TV manufacturers such as Sony and LG.

Four requirements for HDR video to be realized, specifically for the HDR10 standard. 

  • 4K resolution, which means they have 3840 x 2160 pixels. This is four times more than the standard HD resolution of 1920 x 1080 pixels. Having more pixels means having more clarity and sharpness in the image, which is essential for HDR.

  • High contrast ratio, which means it can show a big difference between the brightest and darkest parts of the image. For HDR10, the display device must be able to produce at least 1000 nits of brightness, which is a measure of how bright a screen can get. It must also be able to show blacks of less than 0.05 nits, which is a measure of how dark a screen can get. Having a high contrast ratio means having more details and depth in the image, which makes it more realistic and vivid. LED displays are very good at achieving high contrast ratios, unlike some other display technologies.
HDR led display brightness and contrast ratio
  • 10-bit color depth, which means they can show 1024 shades of each of the three primary colors (red, green, blue). This is much more than the 8-bit color depth of standard video, which can only show 256 shades of each color. Having more shades of color means having more smoothness and richness in the image, which avoids the problem of “banding” or “stepping” between colors. It also means that some parts of the image can be very bright without affecting the rest of the image, such as the sun, a flash, or a fire.

LED Display Contrast Ratio

LED Display Contrast Ratio Definition

According to the definition of industry-standard SJ/T11281-2007 “Light Emitting Diode (LED) Display Test Method,”Contrast is a term that describes how bright or dark the image on an advertising LED screen is. It is calculated by comparing the brightness of the white and black colors on the screen. The contrast ratio is a number that shows how much brighter the white is than the black.

For example, an LED display contrast ratio of 1000:1 means that the white is 1000 times brighter than the black. The higher the contrast ratio, the more clear and colorful the image is. The lower the contrast ratio, the more dull and blurry the image is.

Static and dynamic contrast ratio

: The contrast ratio can be measured in different ways, such as static contrast ratio and application contrast ratio. The static contrast ratio is measured in a completely dark room environment, and it is usually very high, as high as millions to one. The application contrast ratio is measured at an ambient illumination of 10±10% lx, and it is more realistic and practical. According to industry standards, an LED display application contrast ratio greater than or equal to 5000:1 is the highest level of C.

 Different Contrast ratios Among COB, GOB, SMD led displays

SMD LED Display: Black SMD LEDs VS White LED Screen.

Black SMD LED in small sizes, make them perfect for incorporation into instruments and devices. The smaller the chip size, the higher the contrast ratio of the LED display. This is because a smaller chip leaves more black space on the display, which reduces the brightness when the LED is off. Even though a smaller chip also reduces the brightness when the LED is on, the contrast ratio still increases significantly.

Black LEDs have a higher contrast ratio than white LEDs, which means they can produce darker blacks and more uniform colors. The contrast ratio of black LEDs is 8000:1, while the contrast ratio of white LEDs is 3000:1.

  • Power consumption: Black LEDs consume less power than white LEDs, which makes them more energy-efficient and eco-friendly. The power consumption of black LEDs is 350/m2, while the power consumption of white LEDs is 410/m2.
  • Brightness: White LEDs have a higher brightness than black LEDs, which means they can be more visible in bright environments. The brightness of white LEDs is Max. @2000cd/m2, while the brightness of black LEDs is Max. @1500cd/m2.
  • Display effect: Black LEDs can display black or gray colors more accurately and smoothly than white LEDs, which can cause distortion or noise in the same colors. Black LEDs have more stable and softer colors, although less bright than white LEDs.

LED Display Contrast Ratio: COB VS GOB

The contrast ratio of the COB led screen is higher than the SMD and GOB led screens. This is because the COB package does not use a bracket structure to support the chip device, which limits the size of the package body and the light-emitting pixel point. The COB package can use smaller chips according to different viewing needs, which increases the black area on the display and improves the contrast.

cob-led-display-visionpi-painting high contrast ratio copy

LED Display contrast ratio Flip chip COB vs Lateral Chip COB 

The LED display contrast ratio of the flip-chip is higher than the front-mounted chip. This is because the flip-chip does not have electrodes and bonding wires on the light surface, which occupy part of the area that should be light. The flip-chip also has a larger light-emitting area and a higher luminous efficiency. This makes the LED brighter when it is on and darker when it is off, which enhances the contrast.

High Contrast COB LED Display

As aforementioned, the importance of high contrast for mini LED displays is obvious. The combination of full flip-chip and COB packaging technology of the mini LED display is an outstanding contribution to improving the contrast. Therefore, a full flip-chip COB display will be the best solution for a high-contrast ultra-fine-pitch LED display.

High Contrast Outdoor LED Display

The high contrast outdoor LED display designed to perform under direct sunlight incorporates features that optimize visibility and readability, even in challenging lighting conditions. Here’s a closer look at why black LED technology stands out and how it contributes to enhancing display performance in outdoor settings:

Outdoor Black LED Display Advantages

1. Higher Contrast Ratio: By using black LEDs, the display achieves a much darker black than traditional white or grey LEDs. This results in a significantly higher contrast ratio.

2. Sunlight Readability: Traditional LED displays can become washed out under direct sunlight due to their inability to produce true black colors, reducing their contrast.Black LEDs maintain their color integrity and contrast even in bright conditions. The deep blacks create a stark difference against the colored pixels, making the content more readable.

3. Lower Brightness Required:Traditional LEDs often require higher brightness levels to improve visibility in sunlight, consuming more energy.With black LEDs, the need for excessive brightness is reduced, lowering energy consumption while maintaining visibility.

Step 2. Install the connecting plates on the structure. Rotate the hex key clockwise until the screw bolts are inserted. Do not over-tighten the screw bolts yet as you may need to adjust the connecting plates again. Ensure that the seam and flatness between cabinets conform to the standard after each cabinet is installed. Otherwise, make some adjustments, lockout LED lamp boards after they are adjusted horizontally and vertically because the boards will probably be moved during the installation of other lamp boards. Repeat the above steps to install the other cabinets in the lowest row.

4. Power and Signal Wiring

The data wiring process must follow a zigzag order between the cabinets, always starting from the one located at the bottom left. The modules are then connected to the data in and data out ports. Thanks to our system software we can verify the correct wiring of the entire screen with simple tests. Finally follows the color calibration and brightness setting.

 5. LED Modules installation.

After check all the cabinets are well installed, attach the led modules to the cabinet, please check the arrow on the back of the PCB and follow the direction, and connect the flat cable and power cable from the hub to each of the modules. tips: to check the status of each led module on the cabinet, you can use one spare cabinet to test the condition of the led modules by pressing the test button on the hub.

XR Stage LED Video Wall

Green Screen VS XR Stage led wall

 

Will the green screen be replaced by XR Stage led wall? we are witnessing a transformation from green screen to the led wall for video production on film and television sets; virtual production can create a living and dynamic background. Are you interested in this new technology because of its simple construction and affordable cost? Extended Reality (XR) is a cutting-edge technology for cinema, television, and live events.

Within studio environments, XR enables production teams to deliver Augmented and Mixed Reality. Mixed Reality (MR) combines camera tracking and real-time rendering to produce an immersive virtual world that can be seen in real-time on set and captured in-camera. MR allows actors to be immersed in a virtual environment by using high-resolution LED panels or projection surfaces in the room. The material on these panels may be created in real time, presented from the camera’s point of view, thanks to camera tracking technology.

Virtual Production

Virtual production, as the name implies, is the use of technologies generated from virtual reality and gaming to create shots for television and movies. It employs the same setup as our XR studio, but instead of events, the virtual settings may be utilized for filmmaking.

virtual production led display_

What is XR and how does it work?

Extended Reality is abbreviated as XR. It’s a step forward from augmented reality to virtual reality. The technique of expanding the virtual set beyond the LED volume is referred to as XR. A volume, or cave, made of LED tiles can be found in an XR studio.The Immersive XR stage takes over where the physical stage ends, producing an extended reality setting that provides spectators with a dynamic experience.These images depict scenes produced with real-time generative software or gaming engines like Notch or Unreal Engine. . This technology allows the material on these screens to be dynamically generated from the camera’s perspective. As a result, our material travels with the camera. 

Why choose Immersive XR Stage led wall?

 

  • A Production That Is Truly Immersive.
  • Content changes in real-time Seamless camera tracking and switching.
  • There is no color key or spill.
  • Cost-effective and secure.
xr filming led wall

1.Truly Immersive Production.

Developing rich virtual environments that immerse talent in the environment purpose of MR is to give broadcasters and production firms an alive and immersive production environment so that they may generate more appealing content and make faster creative decisions during the production process. MR enables the construction of multi-purpose studio settings, with the complete system adaptable to any sort of programming and any camera arrangement.

2.Content changes in real-time Seamless camera tracking and switching
DPS and camera operators can readily view and explore the environment in the camera thanks to LED displays’ realistic reflections and refractions, allowing for a faster workflow. In a sense, you’re conducting post-production in pre-production. On the screen, you can plan your shots and see precisely what you want.

3There is no color key or spill.

There are many shortcomings of the traditional chromo key technology, such as the rendering of the image is not real enough and high cost for the post-production and personnel. The XR stage perfectly solved these issues. Virtual production eliminates the need for chroma keying in postproduction The XR stage enables significantly faster camera tracking system calibration than the typical green screen. The significantly improve the efficiency of setting up the scenario across several sessions.

4.Cost-effective and secure.

All sorts of scenarios may be generated with the XR stage without having to travel to different locations or attempting to locate them. Filming using an LED volume in a studio reduces the number of locations needed in production, saving money on hiring costs at different sites. When it comes to social distancing and covid-19, a virtual environment is a safe way to keep the cast and crew safe in a controlled atmosphere. With fewer people on set, it’s simpler to social distance and covid-test staff.

How to Build a XR Stage LED Wall

Building an LED panel is not difficult, but building one with the quality and dependability expected by media and film makers is a different story.There is no ready-to-use virtual production system available. Building one necessitates extensive knowledge and expertise with all of the features and elements involved. There’s a lot more to LED screens than meets the eye.

The fundamental aim is to build fewer devices overall by allowing a single unit to do many jobs. LED Poster, LED wall rental, led dance floor and XR stage led wall

Fine Pitch Pitch LED

Pixel Pitch LED, a factor specified by the usage or type of photographs you want to create, is one of the first things to work out. The lower the pixel pitch, the more close-ups you’ll need, but keep in mind that finer pixel pitch implies less light from the LEDs for your scenario.

The refresh rate of the screen has an impact on visual quality. The greater the disparity between the LED screen and the camera’s refresh rate, the more difficult it is for the camera to detect it. Although a high frame rate is ideal, particularly for fast-paced live-action, there are still practical restrictions on content rendering today. Even if the LED panel can display at 120 frames per second, the renderer may struggle to keep up.

Broad-casting level LED WALL

Broad-casting level refresh rate is a must .The success of the virtual stage production depends on synchronizing input sources to the camera and playback on screen. “Syncing the camera settings with the LED is a time-consuming and precise operation. If your LED panels and camera are out of sync, it can cause a variety of visual abnormalities such as ghosting, jitter, and picture distortion. We carry genlock all the way to the end and have a number of features to ensure that the genlock is adjusted down to the nanosecond.”

 Wide colorimetry

It is critical to maintain a consistent color presentation under various viewing angles in order to make the virtual picture more lifelike. We can tune the color science of the LED volume to the sensor and the unique demands of the DP on each project because we can monitor the raw data of every single LED and because we work closely with digital cine camera companies like ARRI.”

COB VS FLIP-CHIP COB LED Display

In the field of LED display, with the development of upstream packaging technology, there gradually form two different LED display panel preparation technologies, SMD ;IMD; COB. We can use these two technologies to produce small-spacing mini LED display screens. And we will share some information about these two technologies with you.

What is COB?

COB (Chip on Board) is a kind of LED display packaging technology. LED light-emitting chips are directly bonded to the module board with high precision and connected to driver components on the module board through special media for overall protection of the light-emitting surface. COB packaging eliminates the two key procedures of turning LED chips into lamp beads and reflow soldering as compared to standard SMD packaging. 

 

Features Of COB LED DISPLAY

1. With Ultra-High Reliability

COB technology eliminates the process flow of SMD light-emitting tube packaging, color separation, taping, and patching, simplifies and improves the reliability of the product production process. Longer Life Span: Without the holder, the LED chip has lower heat resistance, largely increasing its life span

2. Smaller Pixel Pitch allowed

Smaller Pixel Pitch: the pitch of SMD is P1.2-P2.0, while COB is P 0.5-P2.0 .The COB technology  is not limited by the physical size, bracket, and lead of the SMD LED package, and can break through the SMD pitch limit, achieve higher pixel density, and have a more flexible dot pitch design.

3. Larger Viewing Angle: 

COB more likes the surface light source than the SMD, when light refracts, it has less light loss. COB Realizes The Conversion From “Point” Light Source To “Surface” Light Source.No pixel graininess; can effectively control the brightness of the pixel center, reduce the intensity of light radiation, inhibit moiré, glare, and glare to the retina, suitable for close and long-term viewing, not easy to cause visual fatigue, suitable for close-screen viewing.

4. Higher Protective Performance

The PCB circuit board, crystal particles, solder feet, and leads are fully sealed. The advantages of the sealed structure are an obvious-for examples, moisture resistance, anti-collision, prevention of pollution damage, and easier cleaning of the device surface.

Wire bonding COB structure  VS A Flip-Chip COB structure

Wire Bonding COB. In wire bonding COB Also called (face-up cob or Lateral COB), the LED chips are attached directly to the substrate using an adhesive, and their electrical connections are made with thin wire leads. This method is quite traditional and widely used due to its cost-effectiveness and simplicity in connecting the LED chips to the driving electronics.

Flip chip COB, on the other hand, involves mounting the LED chip upside down on the substrate so that the light emits from the top, making direct contact with the substrate. This setup enhances heat dissipation, reduces the thermal path, and generally provides better luminous efficiency and reliability.

lateral chip cob vs flip chip cob

Flip chip cob led display advantages

1. Higher stability. Flip chip packaging technology eliminates wire bonding, eliminating the risk of gold wire breakage and simplifying the production process.

LED COB WIRE BONDING

2. Smaller pixel pitch.  Flip-Chip COB encapsulation is the chip-level integrated encapsulation. Without the wire bonding, the physical space size is only limited by the size of the light-emitting chip, which can achieve higher pixel density.

3. Better visual performance. Regarding display performance, the area of the Flip-Chip is smaller on the PCB board, and the duty cycle of the substrate is increased. It has a larger light-emitting area, which can present a darker black field, higher brightness, and higher contrast Presenting HDR-level display effects.

cob structrure visionpi

4. Cost-effective. There is no welding wire link, simplifying the production process and reducing equipment investment costs. As the industry scales, the product cost will be significantly reduced, especially when the dot pitch is less than 1.0mm.

Therefore, Flip-Chip COB technology is a necessary condition for the realization of MicroLED and will go further in the era of micro-display.

The Future Of direct view led display.

Flip-chip COB is an upgraded version of lateral COB, flip-chip COB improves reliability and visual performance, simplifies the production process, and narrows the pixel pitch. COB is the future of direct view led display 

The Four Levels of Chinese LED Display factories

visionpi manufacturing
  • Level 1: the recently-created and unstructured workshop; and the factories only make the assembly work with all the half-completed product purchased from other suppliers, there are thousands of factories like this.
  • Level 2: the semi-organized factory that got out of level 1 but is still struggling to keep quality & timing under control, they have SMT machines, they can produce led panels themself, and focus on the segmented market, like led poster, rental display, transparent.
  • Level 3: the factory that made big efforts to get organized, with the objective of pleasing large customers, and they usually with many years of experience and their own R&D team and overseas sales team. here we can name a few, chip show, GCL, SBC.Yestech.
  • Level 4: that rare birds like Yaham, Unilumin that applies Lean manufacturing, and that avoids level 3’s rigidity.

In this article, I am excluding Chinese state-owned enterprises, which are a breed on their own.

Most manufacturers are at level 1 or level 2:The 4 levels of Chinese manufacturers

Level 1: the unstructured led display workshop

Typical profile:

  • 0-50 workers, engaged in simple processing (often assembly);
  • Managed by the owner and his family;
  • Not mature quality system and quality control staff;
  • No ability or time to work on complex prototypes before production starts;
  • Focused only on “making production” fast and on the cheap;
  • Can accept small orders, as long as purchasing components in small quantity is possible;
  • Seldom works directly for export customers;
  • Count on other manufacturers or trading companies to get business.

Result: low costs and low MOQs, but needs to be followed very closely by customers.

Level 2: the semi-organized led display manufacturer

This category is a mixed bag. Some export 100% of their output and are very familiar with their market’s quality & safety standards. Others focus more on the domestic market or the most price-sensitive countries (Middle East, India…), and should be avoided by importers from North America and Europe.

Still, it is possible to draw a somewhat typical profile:

  • 50-100 workers
  • Has grown out of the “disorganized workshop” stage
  • Has had to hire a few professional managers because of the growing complexity of operations
  • Has had to hire a few QC employees, to avoid big disasters.
  • But still, low concern for quality among staff and managers (in most cases).
  • May have English-speaking salespeople if direct relationships with foreign customers is a goal.
  • May still get orders mostly from trading companies and other factories.

Result: costs are relatively low, and quality & timing are relatively unstable. The owner’s motivation for your orders still determines their reliability.

Level 3: the organized/Listed led screen manufacturer

Typical profile: 200+ workers, usually established before 2010 with decade experience.

They have tried hard to comply with demanding buyers’ requirements:

  • Every aspect of production is specified in detail;
  • Production is checked thoroughly by QC department;
  • Own R&D team and updating led
  • Hopefully, strong staff discipline to follow the system;
  • a team for export business,and 60-80% of their sales is come from exporting.

Result: few quality issues, but high indirect labor costs (QC, middle management) and low flexibility. Top 10 led sign board manufacturers

Level 4: the continuously improving led display manufacturer

Typical profiles:

  • Part of a large multinational group or a joint venture.
  • Midsize factory with a process-oriented/engineering-oriented general manager.
  • dedicated to segment markets, like transparent led display or soft led display.

They follow the lean model:

  • Regular improvements to material flow and to each process;
  • Errors are prevented or corrected at the source;
  • Staff is trained and supports the philosophy.

Result: high customer satisfaction (close to zero defects; production cycle below 5 days) and relatively low cost (high productivity of operators, limited QC staff, and rework).

Unfortunately, these companies are a very small minority. They usually don’t advertise themselves on B2B directories. They are very hard to find.

What kind of Chinese factories should you work with?

First, a couple of rules to keep in mind:

  • If you work with a supplier that is too large relative to your orders (e.g. you would occupy 1% of their annual capacity), you will be quoted high prices and given poor service.
  • If you work with a small supplier that cannot produce the quantities you order, they will be forced to subcontract production and you will probably be in for a disaster.

My general advice would be as follows:

  • If your orders are very small, you might need to work with a trading company/quality assurance team that will place your orders in a level 1 factory and follow production.
  • If your orders are large enough to work directly with a manufacturer, but not big enough to be interesting to big factories, go for level 2, but you will still need a final inspection service before the shipment to make sure everything settled.
  • If your order is considered large and even big companies actively fight for your business, go for level 3.
  • If you are in a very quality-sensitive market and you cannot afford even 1% of defects, spend time and search for level 4 (but you might not find any in your vertical).

Small importers tend to have the feeling that buying from a large factory is more expensive but more reassuring. There is some truth regarding the higher prices, but risks are not necessarily lower. the fierce competition makes the industry more of chaos. after all, the company needs to survive, if the price allows them little profit, they will have to find a way to saving the cost from the raw material. smaller companies who dedicated one or few product line can be a good one to work with. 

We believe the core comptiveness is on the supply chain managment of a whole supply chain not between companies. VISIONPI dedicated in the supply chain management since the very beginning of the led display industry,back to 2000. we works with hundreds to thousand of importers to make the full adavantage of the supply chain in china.our professionla quality control team and managing system allow us to take the most advantage of the supply chain to provide our cusotmer with the best products.
