When it comes to the display viewing angle, there is a phenomenon worthy of our consideration: LED display, especially outdoor display, the viewing angle is basically people from the bottom up, and the product shape to the existing LED display view, there half of the flux disappeared into the vast sky. Uniformity and clarity LED display technology developed to full color led unit board, uniformity has become the most important measure of the merits of the display. It is often said LED display "splendid little led unit board prices, movie glory," is a serious image problem for uneven between pixels and modules metaphor. Professional thing to say is "dust effect" and "mosaic." Chassis heat well led unit board mounting, resulting in temperature rise due to the graphics card. Workaround: Exclude heat. Check fan is functioning properly, to fan refueling, clean up the dust inside the chassis, failure can be ruled out after solve the heat problem. Reinstall the system, video card or monitor does not support the high resolution due. led unit board offer, Gao Jin photovoltaic (certified), led unit board provided by Jinan Optoelectronics Technology Co., Ltd.
