P5 indoor full color display Supply preferred Shaanxi Hi-Tech Optoelectronic Technology Co., Ltd. 0 2 9 8 5 4 5 3 6 0 2 LED screen body to take advanced technology 1. Screen design of the general requirements for a standard display body module design, the entire screen of the same unit modules, interchangeable system to work more than five years, the life of more than 10 years. 2. Screen temperature and humidity control measures in the design of the design of the LED display is a large LED display, in order to ensure its life and MTBF, you must do the following: (1) at the opening screen to ensure good working condition ventilation conditions, reduce the control circuit and a light emitting diode aging rate, to prevent oxidation of the solder joints. (2) If the display is in a closed state, in the larger temperature difference between day and night and the air humidity is high inside the display case where condensation occurs. Once inside condensation will severely damage joints. This is why many screen after a period of time to the cause sudden failure when needed. And we offer the products to ensure good overall performance. Since the display driver board extensive use of high-speed CMOS circuit, the circuit board 95% of the power is concentrated in the constant current driver chip. Solve the problem of heat dissipation board simply focus on solving the heat problem can be constant current driver chip. (3) separate lamp drive circuit board module with LED display and LED driver circuit board independent design, that lamp drive separation, this design can reduce the maximum mutual thermal interference between the two, to avoid driving circuit (chip) the heat generated in the superimposed work LED light tube, resulting in a double heat accumulation effect, to avoid performance degradation LED light tube. And the design of the lamp drive separation between a certain interval, the space between the cooling system in the body can rapidly screen action hot and cold convection help screen body heat.
