P4 SMD full-color LED display manufacturers led display production method Advantages - using scanning and distribution modular design improves system stability and reliability. Display specifications PH10, PH14, PH16, PH20, PH25, PH31.5 (highway screen) and other pixel control. Outdoor LED full color display each light emitting point includes red, green, and blue 256 gray constitute 16,777,216 colors. Display the body of computer control center, fully equipped programming software and playback software, electronic displays and electronic display window formed correspondence, display real-time synchronization, you can easily change the screen size. With a view, low power consumption, uniform color, screen thickness of thin, light screen body weight, low failure rate, easy to maintain and easy to operate, regulate the design, showing good results, high brightness, the display mode diversification, reliability weather and other characteristics led display production methods to install - outdoor LED electronic display with a bright background, complex climate (humidity, dust), open space, etc., and therefore a higher demand for LED. Blue-outdoor full color display, take into account all the environmental requirements: 1. screen to install lightning protection equipment and buildings. Display body and cover good grounding, grounding resistance of less than 3 ohms, a large current caused by lightning discharge in time; the display unit may be combined with strong electric magnetic attacks caused by lightning and Screen 2. Screen and architecture We must be strictly water leak; Screen have good drainage measures in the event of a smooth water emissions; attention to water and moisture. Display installed outdoors, often sun and rain, wind and dust cover, poor working conditions. Electronic equipment is wet or damp can cause serious short circuit or even fire, causing malfunction or a fire, resulting in losses; 3. Use the operating temperature between -40 ℃ ~ 80 ℃ industrial grade integrated circuit chip to prevent the winter temperature is too low to display screen can not start. 4. Install ventilation cooling, so that the screen body internal temperature between -10 ℃ ~ 40 ℃. Screen behind the top of the installed fan exhaust heat; active screen itself must have some heat, if the ambient temperature is too high heat and bad, the integrated circuit may not work properly, or even destroyed, so that the display system fails work; 5. In order to ensure the long-distance visible in strong ambient light conditions, you must use ultra-high-brightness light-emitting diodes; increase contrast wide audience, sight distance requirements far and wide field of vision requirements; environmental light changes, in particular, may direct sunlight. 6. The media use the new wide viewing angle tube, wide viewing angle, color pure, consistent coordination, life over 100,000 small
