What is Carbon Fiber?

Carbon fiber is a material known for its impressive strength-to-weight ratio, high tensile strength, and resistance to temperature fluctuations. These properties stem from its composition—thin strands of carbon woven into a fabric and set within a plastic resin. Its application in industries such as aerospace and automotive has been well documented, but its use in LED display manufacturing marks a significant leap forward, offering an array of benefits over traditional materials.k about and use LED displays, making them more sustainable, versatile, and visually striking. The future of digital signage is light, durable, and bright, thanks to carbon fiber technology.

Durability: Carbon fiber’s resistance to corrosion, impact, and extreme weather conditions means that LED displays can last longer and require less maintenance, even in harsh outdoor environments. This durability also translates to cost savings over the lifespan of the display.

Energy Efficiency: Better heat dissipation is another hallmark of carbon fiber LED displays. Efficient heat management not only prolongs the life of the LEDs but can also contribute to lower energy consumption, making it an eco-friendlier option.

Aesthetic Flexibility: With its sleek and modern look, carbon fiber can provide aesthetic advantages, allowing for more innovative and visually appealing designs in digital signage.

Applications of Carbon Fiber LED Screen

From towering billboards to dynamic stage backdrops, carbon fiber LED displays are finding their niche. Their lightweight nature makes them particularly suited for mobile advertising platforms and temporary installations. Moreover, their durability and efficiency open new possibilities for outdoor advertising, sports arenas, and exhibitions, offering both practical and environmental benefits.

Challenges and Considerations

Despite the many advantages, the adoption of carbon fiber in LED displays is not without challenges. The initial cost can be higher than traditional materials, and specialized manufacturing processes are required. However, as technology advances and production scales, these obstacles are gradually being overcome, making carbon fiber more accessible and cost-effective.

Future Outlook

The potential for carbon fiber in the LED display industry is immense, with ongoing research and development hinting at even greater advancements. As manufacturing techniques evolve and costs decrease, we may see carbon fiber becoming the standard for digital signage, pushing the boundaries of what’s possible in design, efficiency, and functionality.

Carbon fiber LED displays represent a significant leap forward in digital signage technology, offering unmatched benefits in terms of weight, durability, and energy efficiency. As the industry continues to innovate, the adoption of carbon fiber could revolutionize how we think about and use LED displays, making them more sustainable, versatile, and visually striking. The future of digital signage is light, durable, and bright, thanks to carbon fiber technology.

What is led display scan mode

Feb 17, 2023 | knowledgebase | 67 comments

led display scan mode

Scan mode, also called Scan rate or scanning driving, refers to the number of LED pixels that can be connected to a single driver IC. Each pixel is connected to a pin on the driver IC on the PCB board. The number of drivers required on a PCB board design to illuminate the pixel pitch determines the scan type. 

Two types of Scan modes:

1. Static scanning: 

Static scanning is to implement “point-to-point” control from the output of the driver IC to the pixels. 

2. Dynamic scanning:

Dynamic scanning is to implement “point-to-column” control from the output of the driver IC to the pixel points. 

Several factors, including the type and performance of the driver IC, refresh rate, grayscale, and pixel pitch directly influence the scan design.

A single driver IC has 16 pins output and can drive a maximum of 16 LED chips. In static drive mode, all LEDs on the LED module can be driven by the IC simultaneously, as illustrated in the following image.
scan rate of led screen

Static: A single-driver IC has 16 pins and can drive a maximum of 16 LED chips. In static drive mode, all LEDs on the LED module can be driven by the IC simultaneously, as illustrated in the following image.

1/2 Scan: In 1/2 scan mode, the IC drives a set of 1/2 LEDs on the module at a time, and subsequently switches to another set of 1/2 LEDs.

1/4 scan: 1/4 of LEDs on the module are driven by IC at one time, and next time there are other 1/4 LEDs that are driven.

Taking a 1/45 scan P1.875 design with the LED and driver IC on the same side as an example:

Module size:300×168.75mm; pixel resolution: 160×90=14,400 dots.

Each LED contains 3 color chips(1R1G1B), so there is a total of 14,400×3=43,200 colors in one led module.

with 1/45 scan driving mode. only 43,200/45 =960 colors are required to be lit up each time.

Since each Driving IC has 16 pins. so the total amount of Driving ICs required for one module is 960/16 = 60 pcs (2o pcs for Red color;20 pcs for Green Color;20 pcs for Blue color)

Why is Dynamic driving mode essential? 

A static driver design (P1.875) would require  2700 16-channel driver ICs and current setting resistors. That will lead to an increased number of PCB layers and costs, on the other hand, the brightness is much higher but the current is also too high. 

A dynamic driving mode design utilizes a single driver IC to activate more LEDs, conserving space on the PCB board and optimizing the budget and driver IC’s layout. However, when aiming for high image quality, there is a trade-off between high grayscale and high scan rate. As a result, a smaller pitch necessitates more time-multiplexing in the design. Typically, P2.5 displays implement a 1:16 time-multiplexing design, whereas displays with a pitch of 2 mm and below require time-multiplexing above 1:16.

Scan Mode,brightness,refresh rate and grey level

The lower the scan rate, the better the performance and the more expensive it will be.

  • Brightness

    The higher the scan the more LED pixels one driver needs to light at once. The brightness is doubled compared to a 1/2 scan, and with a 1/4 scan, the brightness doubles compared to a 1/8 scan. Nevertheless, adjusting the software through experimentation can reduce the brightness if high brightness is not essential. in some cases, the outdoor fine pixel pitch led display requires a super high brightness of 6000-10000nits, the high brightness gold wire LED can provide the required brightness in a lower scan mode (1/13scan 1/16 scan)

  • Power Consumption 

    Increasing the scan rate results in higher power consumption. A simple formula accurately reflects this correlation: for instance, a 1/8 scan consumes twice as much power as a 1/16 scan. The current is also a limiting factor. In the future, factories may reduce current, thereby diminishing both power consumption and brightness. commom cathode technolgy can reduce the power consumption without sacrifce the brightness.

  • Refresh Rate

    The refresh rate of a screen is indicated in hertz (Hz) and signifies how frequently the image is updated per second. When the number of scan lines is doubled, the time required to illuminate all LEDs will increase twofold, and the refresh rate will be halved. Thus, increasing the number of time-multiplexing in a design makes it more challenging to achieve a high refresh rate. Decreasing the scan rate will reduce the refresh rate and vice versa. However, the PCB design and type of driver IC also influence the refresh rate. Incorporating a driver IC with an embedded SRAM can enhance the refresh rate by decreasing the time required to transmit grayscale data. If the driver IC supports GCLK multiplier technology, the refresh rate must be doubled.

Choosing a scan mode for LED display is a crucial decision that depends on various factors, such as brightness, power, refresh rate and cost. A higher scan mode is not always better, nor is a lower one. The goal is to design an optimal LED screen that meets the desired specifications.
