The role of LED display video processor
LED display industry in China from the beginning in 1990, from now on there has been nearly 30 years of history. In this process, LED special video processing equipment, from scratch, in the process also gradually mature, the video processor witnessed the birth of full-color LED display as well as the growth and development of the whole witness and iconic equipment.
Video processor witnessed the birth, growth and development of full-color LED display throughout the witness and iconic equipment. LED video processor performance advantages and disadvantages have a direct impact on the led display effect. In a nutshell, LED video processor, is specialized in the production of LED display dedicated supporting equipment. And it needs to accomplish the task, simply put, is from the external such as blue dvd computer, high definition play box image signal into LED display can accept the general signal. In this process, the LED video processor plays the following roles:

First, the image signal source such as blu-ray dvd computer, high definition playback box, etc. Provide the signal resolution have fixed specifications reference VESA ITUSMPTE and other standards and led display modular splicing display, resolution specification conversion: generally speaking. Make its resolution can be almost any value. The video processor is responsible for a variety of signal resolution is converted to the actual physical display resolution of the led display.
Second, most of the color space of the image signal is relatively small than the NTSC in order to let the led display screen has excellent image display effect, color space conversion: LED display color gamut is very wide. Must be color space conversion.
Third, in real life, many input signal source most of only 8 bits. Therefore, the bit depth enhancement: the current led display gray level has been upgraded to 16 bits, 17 bits. With the arrival of the high-definition display era in the footsteps of 10-bit or even 12-bit disposal technology in the video processor has been the trend.
Fourth, the need for image scaling, scaling: resolution specification conversion process. Whether the resolution increases or decreases, can be perfect for the screen to display the complete image.
Fifth, image processing and enhancement technology: digital image processing technology from the 1920s to the present development presents a large number of patented technologies. Than DCDiA CC2A CM3D and other Emmy Award-winning Faroudja laboratory of a series of patented technologies. These technologies undoubtedly make the visual effect of the image has been greatly improved.
