The Beijing Public Aude Technology Development Co., Ltd. The new product is one indoor full color led display products. PH2.5 is one indoor SMD led full color display the highest clearance model, each square meter contains 160,000 pixels, is five times the currently more widely used definition PH6 display. It uses SMD0606 LEDs dispositions. Play full 1080P high definition video files, high-definition LED display area PH6 physical resolution of 1920 × 1080, 70 square meters area needs to be done; if PH2.5 type of product area of ??only 13 square meters needs to be done. Cooling problems led indoor ultra high-definition display technology has been one of the highlands difficult to overcome. As we all know, LED display during operation generates heat, if too dense pixel LED display, no good thermal performance, it will lead to a large number of dead lights LED display phenomenon, the more serious will directly affect the display stability. High density LED display is also often occur Weld, short circuit and other issues. And this series of questions are not independent, only consider the various factors in order to manufacture a stable performance of high-definition LED screen. When customers need to provide the following information available screen: 1. Statements made display Installation environment: indoors or outdoors, to be installed on the wall or other. 2. Please describe the display size to choose, such as uncertainty, please consult the sales staff to provide proposals. Common outdoor full color LED display specifications: P6, P8, P10, P12, P16, P20 common indoor full color LED display specifications:. P1.9, P2.5 P3 P3.75 P4, P5, P6, P7 .62, P8, P10 3. to provide the best viewing distance of the majority of the audience's screen after installation. 4. Please indicate to do the display area, it is best to determine the specific length and width of the display, so that we can give you a more detailed display production offer solutions.
