LED display virtual pixel technology is a technology that simulates pixels through software algorithms to improve the pixel density and image quality of the display.

The following is a detailed explanation of LED display virtual pixel technology:

Definition

Virtual pixels (also called logical pixels or integrated pixels) are pixels simulated on LED displays through software algorithms. They do not correspond to actual physical pixels on the display. The core of virtual pixel technology is to use the brightness and color information of adjacent physical pixels to calculate more virtual pixels through algorithms, thereby improving the resolution and image details of the display.

Working principle

1. Pixel simulation: Virtual pixel technology inserts virtual pixels between adjacent physical pixels through software algorithms. The brightness and color information of these virtual pixels are calculated based on the data of adjacent physical pixels.

2. Resolution improvement: Due to the addition of virtual pixels, the number of pixels on the display is visually increased, thereby improving the resolution of the display. This improvement can be achieved without increasing the number of physical pixels, which helps to reduce costs.

3. Image quality improvement: Virtual pixel technology can reduce the gaps between pixels, making the image more continuous and smooth. At the same time, by optimizing the algorithm, the image's detail expression and color richness can also be improved.

Application advantages

1. Improve display effect: Virtual pixel technology can significantly improve the display effect of LED display screens without increasing hardware costs. It can make images more delicate and clear, and colors more vivid and full.

2. Reduce costs: Since virtual pixel technology does not require the addition of additional physical pixels, it can reduce the manufacturing cost of the display screen while maintaining or improving the display effect. This is particularly important for large-scale applications of LED display screens.

3. Enhance market competitiveness: LED display screens using virtual pixel technology have advantages in display effect and cost performance, which helps to improve the market competitiveness of products.

Example description

Take a certain model of LED display screen as an example. When R, G, and B are distributed in 2, 1, and 1 (that is, each pixel consists of two red tubes, one green tube, and one blue tube), through virtual pixel technology, the number of image pixels that can be displayed by the display screen can be four times the number of actual physical pixels. This means that under the same display area, the display screen using virtual pixel technology can present a more delicate and clear image effect.

Conclusion

LED display virtual pixel technology is an innovative display technology that simulates pixels through software algorithms to improve the resolution and image quality of the display. 

This technology has the advantages of reducing costs, improving display effects and enhancing market competitiveness, and is one of the important directions for the development of LED displays in the future.

Also known as shared pixels or dynamic pixels, pixels that are four times the number of physical pixels are quickly sent to the physical pixels four times according to odd-even columns and odd-even rows for display. 

The effect is equivalent to reducing the spacing by half. Its cost is basically the same as that of traditional methods, but it can achieve four times the original resolution.
