P4 indoor full color LED display LED display offer major specifications of the outdoor screen (P10-P12-P14-P16-P20-P25-P31.25) SMD indoor full color screen (P4-P5-P6-P7.62-P10 ) Led display series, indoor full color LED display (PH5, PH6, PH7.62, PH10, PH12,) Outdoor Full Color LED Display (PH10, PH12, PH16, PH20, PH25) outdoor color LED display, LED electronic screen , LED large screen, LED modules, LED cabinet, indoor surface mount triple P6, led display, indoor full color, outdoor full color display, LED display, LED indoor and outdoor full color screen, LED indoor SMD full color , LED display control system, sports venues display game information, video game, LED advertising screen; bars, discos and other entertainment, LED electronic display screen manufacturers in Shenzhen led company LED display is a system integration products, require LED closely with packaging manufacturers and vendors display applications, strengthen technological exchanges, following on from the selection and use of perspective on the full color display for knowledge 1, anti-static screen assembly plants should have good anti-static measures. Special anti-static, anti-static flooring, anti-static iron, anti-static mat, anti-static ring, anti-static clothing, humidity control equipment grounding (especially cut legs) are all basic requirements, and use electrostatic analyzer regular testing . 2, the drive circuit design company in Shenzhen led display driver board display driver IC module arrangement will affect the brightness of the LED. Since the driver IC output current board PCB transmission distance too far, will make the transmission path pressure drop is too large, affecting the normal operating voltage of the LED lead to decrease in brightness. We often find around the LED brightness of the display module is lower than the middle of some, it is the reason. Therefore, to ensure consistency of display brightness, we must design a good driver circuit distribution. 3, the design current value LED nominal current of 20mA, is generally recommended to use the maximum current does not exceed 80% of the nominal value, especially for small spacing display, due to poor heat dissipation, but also to reduce the current value . Based on experience, due to the red, green and blue LED decay rate inconsistency, targeted to reduce blue, green LED current to maintain the display after prolonged use white balance consistency 4, mixing light Shenzhen led display Companies with a color different brightness profile of LED lights need to mix, or in accordance with the discrete law insert lights diagram designed to plug lights, to ensure that the entire screen for each color brightness consistency. This step, if there is a problem, there will be inconsistencies local brightness of the display phenomenon, directly affect the display LED display. 5, the degree of control the vertical line LED lamp is for when the furnace have enough technology to ensure the LED perpendicular to the PCB board. Any deviation will affect the already set the LED brightness uniformity, brightness inconsistent color. Outdoor color P10 \ P16 display prices in Shenzhen led display company 6, wave soldering temperature and time to strictly control the wave front welding temperature and the furnace, it is recommended as follows: preheat temperature 100 ℃ ± 5 ℃, the maximum does not exceed 120 ℃, and the preheating temperature rise steadily requirements, soldering temperature of 245 ℃ ± 5 ℃, welding time recommended no more than 3 seconds after the furnace avoid vibration or shock LED, until the resumption of normal temperature. Temperature parameters of wave soldering machines to regular testing, which is determined by the characteristics of LED overheating or temperature fluctuations will cause direct damage to the LED or LED quality problems, especially for such a small size of 3mm round and oval LED. LED display LED is not lit in the event, often more than 50% probability caused by various types of Weld such as LED pin Weld, IC lead Weld, Pai Pai mother Weld and so on. Improve these problems requires strict to improve the process and strengthen the quality inspection to solve. Vibration test before leaving the factory may well be a good test.
