In terms of the relationship between uniformity and clarity of the display, the industry there is often erroneous understanding, that is an alternative to the resolution clarity. 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 increased resolution, while ignoring uniformity, led display installation, to improve clarity is no doubt. Imagine a grave there, "dust effect" and "mosaic" of the display, even if it's small physical pixel pitch again, led electronic display with a resolution so high, it is impossible to get a good image clarity. At present, led full color, fine pitch LED display is still in the development stage rise, as in the actual purchase of, led, the user should not blindly chasing the trend and ignore the other factors. A cost-effective small pitch LED system is the joint effect of many factors, but three paper emphasizes, it is the object the user application focus in the purchase. When we install LED display, how to calculate the LED display advertising screen size, how to select the appropriate location to install? That is nice to achieve eye-catching effects and enhance the overall image of the installation led display, led, Gao Jin photoelectric provided by Jinan Optoelectronics Technology Co., Ltd. Gao Jin.
