How can we control and improve the technology of LED full-color display pixels?

The most commonly used methods at present are: 1. Pixel sharing technology 2. Dynamic pixel technology 3. Virtual pixel technology!

Their working principles are described as follows:

1. Pixel sharing technology: A complete independent pixel of the display terminal is refreshed by the information of multiple adjacent pixels in the signal source in a time-division multiplexing manner. It can be understood that multiple pixels in the signal source share a complete independent pixel of the display terminal in a time-division multiplexing manner.

2. Dynamic pixel technology: split a pixel into several independent LED units. Each LED unit reproduces the corresponding primary color information of several adjacent pixels in a time-division multiplexing manner.

3. Virtual pixel technology: In the display system, when the displayed information scrolls in a certain direction in a certain way, a series of moving, physically non-existent virtual pixels will be generated between two adjacent pixels by utilizing the characteristics of human visual pause, thereby adjusting each LED tube to enhance the resolution of the LED display to achieve the best image effect. In theory, the image resolution can be increased by 4 times.

In short, the technical indicators of the full-color LED large screen include the following aspects in addition to pixels: sufficiently high brightness, grayscale, scanning refresh rate, viewing distance and viewing angle; the value of the LED display is reflected in aspects such as color reproduction, video signal processing capabilities and structural technology.

MCU LED light flashing program
We have completed the program for lighting up the LED light in the second lesson, which is to set LED = 0. The program for turning off the light is also very simple, which is LED = 1. Now that we know how to turn on and off, if we add a delay between turning on and off, and repeatedly turn the light on and off, it wil

Can you hold on? A detailed explanation of the most powerful LED lighting reliability test!
As a new force in light sources, LEDs emit light in a completely different way from traditional light sources. They emit light by using the recombination of electrons and holes in the semiconductor PN junction. The difference in the way they emit light determines the essential difference between LEDs and tradition
