1.High level grayscale control system of led panel
The grayscale control is vital to the display effect, so we use hardware FPGA to code the 4096 grayscale, and then take 256 grades from them. It’s real time and improves the display effect greatly. We use the technology of anti-jamming to video receiving circuit, storage circuit, high-speed circuit and scanning control circuit, and improve the refresh speed to 300Hz, to make the images exquisite and steady, to ensure the effect in true color with 24 digital figures to show the beauty of the nature.
2.Unique video processing technology
In order to make images more vivid, the non-linear correction technology is put to use to enhance the visual effect; picture edges are strengthened to make images more clear; contrast technology, burring technology and noise cancellation technology together to improve the stability of video images.
3.Excellent dynamic effect
The refresh rate is up to 300Hz, and the frame rate 60Hz, which satisfy the requirements of video images, also show the motion, and no flashing or flickering.
