The number of times the content can be repeatedly displayed on an outdoor LED display screen per second is called the refresh rate. When the refresh rate is low, the image will flicker, especially when the flicker is too obvious during video shooting, so it must be maximized Improve the refresh rate to ensure the stability of the display.
The LED display of the image uses an electronic light-emitting system to display the result of image conversion of the digital signal. The special video card JMC-LED came into being, and formed a unified compatibility with VGA and video functions on the basis of the PCI bus using a 64-bit graphics accelerator, so that the video data was superimposed with the VGA data, and the lack of compatibility was improved. Using the full-screen method to capture the resolution, the video image can achieve full-angle resolution and enhance the resolution effect, eliminate the problem of edge blur, and can zoom and move the image at any time, and can respond to different playback requirements in time. Effectively separate the red, green and blue colors to enhance the true color imaging effect of the electronic display.
