Virtual Pixel COB LED Display

Dec 8, 2023 | Technology | 1 comment

What is Virtual Pixel Technology

Virtual Pixel Technology,also called dynamic pixel technology, is a technique that uses software algorithms to control the LED units in a display, so that each unit can contribute to the image of multiple pixels, thus increasing the resolution of the display by up to four times. It is different from the real pixel, where each unit corresponds to one pixel.

For example, a conference all-in-one machine that uses Virtual Pixel Technology can achieve a near 4K resolution with the same number of LED units as a 2K resolution machine. This improves the display quality and uniformity, while reducing the cost. It is a good choice for most users who want a high-definition display.

Virtual pixel Micro COB LED Display 

Virtual Pixel Technology is also a special innovation for COB packaging, which allows the RGB LED chips to be arranged in any way, unlike the SMD small pitch display technology. 

Virtual pixel display technology is a new way of making Micro LED display products that are more cost-effective and high-resolution. It uses a different hardware and software design than the traditional RGB arrangement of LED chips. Instead, it adds a green LED chip to each pixel and uses a special algorithm to create four virtual pixels from one physical pixel. This reduces the pixel pitch by half and increases the resolution by four times, while using fewer LED chips and lowering the production cost. Virtual Pixel-COB display technology is an innovative and advanced solution.

Advantages of COB Virtual Pixel Technology

“Virtual pixel technology can make LED display screens have more than twice the visual clarity at almost the same cost. It is a magic tool for making LED display screens more affordable and high-quality!” Industry experts said that virtual pixel technology is very important for LED direct display, which is a type of display that becomes harder and more expensive to make as the pixel pitch gets smaller.

 

Take the most popular product,p1.56 136-inch all-in-one LED TV, for example. the 5 square meters LED display only has a 2K resolution, which is not enough for displaying 4K and other high-quality content. It also has a noticeable “pixelation” problem when viewed from a closer distance.

Virtual pixel technology can solve this problem by increasing the logical pixels in the resolution to 4K levels, with only a small increase in cost. This means that the screen can look much clearer and sharper, even though it is not using real physical 4K pixels. Virtual pixel technology is a cost-effective, reliable, and mature technology that can enhance the picture quality of LED direct display screens.

Dynamic Pixel COB LED Display

Disadvantages of Virtual pixel COB.

Dynamic pixel technology is not a perfect solution for Micro LED display products.

  • The inherent nature of pixel sharing in virtual pixel technology can lead to a degradation in display quality as the level of virtual enhancement increases. Observations from current display implementations indicate that, at closer viewing distances, the imagery may present a granular appearance, with static text particularly susceptible to displaying jagged edges. This has sparked some skepticism within the market, with critiques suggesting that virtual pixel products might mislead consumers. Such sentiments contribute to a lack of enthusiasm and support for the technology.

virtual pixel ,dynamic pixel cob led display text display
  • It does not use real physical pixels, so it may not work well in some situations. It also makes the chip work harder and faster, which may cause it to wear out sooner and decrease the life span.

Dynamic Pixel COB LED Display for Commercial Advertising

From an objective standpoint, virtual pixel technology does exhibit tangible limitations in image fidelity. Beyond a certain proximity, distinguishing between the effects of virtual and actual pixels becomes challenging for the observer. However, it’s important to consider the technology’s application context. Beyond specialized domains such as command and control centers or medical imaging, where precise visual detail is paramount, the demand for high-fidelity close-viewing experiences in settings like conference rooms and commercial spaces is relatively modest. These environments represent the niche where virtual pixel technology can indeed shine, leveraging its capabilities where they align with the practical requirements of the application.

Advantages of Virtual cob led display in commercial advertising 

Cost-Effectiveness: By requiring fewer physical pixels to achieve high resolutions, dynamic pixel COB LED displays significantly reduce manufacturing and operational costs. This makes them an economically viable option for businesses seeking high-quality advertising solutions without the high expense typically associated with large or high-resolution digital screens.

Energy Efficiency: Lower pixel density translates to less energy consumption, as fewer LEDs are needed to create an image. This energy efficiency not only reduces operational costs but also aligns with growing environmental sustainability goals among corporations.

Durability and Reliability: COB technology inherently offers greater protection for LED chips, as they are encapsulated directly on the board. This encapsulation provides superior resistance to impact, moisture, and dust, extending the lifespan of the display and ensuring consistent performance in various commercial settings.

Versatility and Visual Quality: Dynamic pixel COB LED displays can adapt to a wide range of commercial advertising needs, from outdoor billboards to indoor signage. They offer excellent visual quality, with vibrant colors and deep contrasts, making them highly effective for capturing consumer attention in competitive advertising environments.

Future Outlook

When we want to make display screens with very high resolution, like 4K or 8K, it becomes very hard and expensive to do. Also, when we look at the screens from a normal distance, like how we use our phones or watch TV, we cannot see the difference between more or less pixels. So, it does not make sense to keep adding more pixels to the screens. Instead, we should make products that look good and clear to our eyes. That is why virtual pixel technology is very popular. It makes the screens look better without using too many pixels.

The future of commercial advertising with dynamic pixel COB LED technology appears bright, with continuous advancements expected to further enhance resolution, cost-efficiency, and application versatility. As businesses increasingly seek innovative ways to engage with audiences, dynamic pixel COB LED displays stand out as a promising solution that balances cost, performance, and visual appeal. Their adaptability and efficiency position them as a preferred choice for advertisers aiming to make a significant impact in a crowded market.

Aug 12, 2023 | Technology | 7 comments

TrendForce research data shows that the LED small-pitch display screen market will reach US$4.232 billion in 2022, a growth of 12% compared with the same period of time. In addition, against the backdrop of the Russian-Ukrainian conflict and inflation, the overall demand for LED displays shrank last year, and display manufacturers have been more active in promoting ≤P1.0 mini/micro led screen.

MIP LED DISPLAY

History of LED display package technology:

The development of LED screen package technology from DIP to SMD to IMD to COB is a process of innovation and improvement in response to market demand and technological progress.

  • DIP stands for Dual In-line Package. It is the oldest and simplest packaging method, which involves inserting two pins of each LED chip into a plastic holder and soldering them to the PCB board. DIP packaging has the advantages of high brightness, good heat dissipation, and low cost, but it also has the disadvantages of large size, low resolution, and poor color uniformity. DIP packaging is mainly used for outdoor displays with large pixel pitches.
  • SMD stands for Surface Mounted Device. It is the most widely used packaging method in the current LED display industry, which involves fixing the LED chips on a bracket, connecting them with gold wires, and protecting them with epoxy resin. The SMD package can integrate red, green, and blue LED chips into one lamp bead, which can be soldered to the PCB board by reflow soldering. SMD packaging has the advantages of small size, large viewing angle, good color mixing, and high reliability, but it also has the disadvantages of low brightness, poor heat dissipation, and high cost. SMD packaging is mainly used for indoor displays with small pixel pitches.
  • IMD stands for Integrated Matrix Device. It is a relatively new packaging method that combines the advantages of SMD and COB. It uses surface mount technology to fix the LED chips on a metal substrate and then covers them with a transparent resin film. The IMD package can achieve a smaller pixel pitch than SMD and also has better protection, heat dissipation, and contrast than SMD. However, IMD packaging still faces some challenges such as high cost, complex processes, and low yield.
  • COB stands for Chip on Board. It is another emerging packaging method that directly mounts the LED chips on the PCB board and then encapsulates them with epoxy resin or silicone gel. The COB package can achieve a very small pixel pitch, even reaching the level of mini LED and micro LED. It also has excellent protection, heat dissipation, contrast, and reliability. However, COB packaging also has some drawbacks such as high cost, difficult repair, and color inconsistency

COB’ Challenges 

COB LED display can achieve a very small pixel pitch, even reaching the level of mini LED and micro LED. It also has excellent protection, heat dissipation, contrast, and reliability. However, COB LED display also faces some challenges

Maintenance

Difficult to repair a single lamp For COB lamps, single-lamp maintenance is relatively challenging. One of the biggest problems is that when repairing a lamp, the surrounding area will be affected by the welding torch, and a ring will appear around the lamp.

Color consistency

LED displays with COB are prone to modular color differences. When the scale of COB production is not large enough, the cost of chip and color binning is high, and the finished display screen needs to be calibrated to improve the display consistency.

High Manufacturing Cost

COB packaging works on a large board that has up to 1024 led chips. which means all led chips must be properly bonded on the board, This brings a big challenge to the Mass transfer device and craftsmanship, ” Compared with SMD, if one single lamp is broken during SMD packing, it only needs to replace one lamp,

However, after the packaging of 1024 lamps in the COB package is completed, a test must be carried out, and the glue can only be sealed after all the lamps are confirmed to have no problems. How to ensure that all the 1024 lamps on the whole board are intact, the one-time pass rate is a very big challenge.

Finished product pass rate is a challenge For COB module production, after the chips are sealed, the IC drive device must undergo a reflow soldering process. How to ensure that the lamp surface will not be damaged by the high temperature of 240 degrees in the furnace during the reflow soldering process is another big challenge.

Visionpi’s patented mass transfer technique is a novel approach for transferring millions of micro LED chips accurately. With the mass transfer technology, the UPH of micro & mini LED displays is more than 2.5KK, and the mass production yield rate is more than 99.999%.

Cost of Mip 

In the printing and mounting process of COB, the higher pixel density of micro led and smaller soldering pin of the Mini LED chip bring big challenges to the SMT stencil and die-bonding equipment.

MIP technology can avoid the problem of poor quality of the whole panel due to a few led chip’ failures, and greatly reduce the cost of rework. In addition, MIP is compatible with traditional SMT production equipment and mature SMD technology and lowers the cost of transfer.

COB VS Mip

 Stability: COB packaged LED displays have higher quality because they do not use brackets, but use silicone or conductive glue to directly paste the chips on the substrate, and then perform wire bonding to achieve electrical connection. MIP packaging is to interconnect the chip electrodes and the substrate electrodes through an interconnect bracket after the LED chip electrodes are made.

Manufacturing Cost:   the P1.2 Mip led screen is comparable in cost to the COB 1.2 led screen. when the dot pitch is less than P1.2, and the comprehensive manufacturing cost of MIP technology is lower than COB technology and SMD technology.
