"Low light high ash" is a prerequisite to ensure viewing comfort, led unit board prices, user primary concern in the purchase of a small pitch product is LED brightness problem. In traditional LED display technology, the screen brightness will reduce loss of gray, and the loss of gray will directly affect picture quality, therefore, an important criterion Choi led unit board, high-quality small spacing is to reach "Low light high ash" technical indicators. In terms of the relationship between uniformity and clarity of the display, the industry is often erroneous understanding of existence, led unit board buying, that is an alternative definition resolution. In fact, the display resolution of the display resolution of the human eye, uniformity (SNR), brightness, contrast and many other factors of subjective feelings. Simply reduce physical pixel pitch to improve the resolution, Hebei, led unit board, to the neglect of uniformity, to improve the clarity is no doubt. Imagine a grave there, "dust effect" and "mosaic" of the display, even though its physical pixel pitch and then a small, high-resolution and then, it is impossible to get a good image clarity. led unit board manufacturers, Jinan Gao Jin (certified), Hebei, led unit board provided by Jinan Optoelectronics Technology Co., Ltd.
