Xingtai, Handan indoor outdoor full color LED electronic display outdoor big screen Shanxi Qinhuangdao large outdoor screen in Xingtai, Handan indoor outdoor full color electronic display LED outdoor big screen Shanxi Qinhuangdao large outdoor screen in Xingtai, Handan indoor outdoor full color electronic display LED outdoor big screen Qinhuangdao Shanxi large outdoor LED display screen analyzed Eight Note outdoor full color LED electronic display indoor outdoor big screen led outdoor big-screen special use: high quality LED also need a good use and the environment, summed up in the following eight Use points: 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, 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, welding 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. 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 . According to experience, due to the red, green and blue LED decay rate inconsistency, targeted to reduce blue, green LED current value to keep the display after prolonged use white balance consistency. 4, LED lamp with a color mixing different brightness profile of need mixed light, or designed in accordance with the discrete law insert lights diagram insert 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. 6, thermal design LED work will heat temperature will affect LED decay rate and stability, so the thermal design of PCB, cabinet ventilation design will affect LED performance. 7, Weld control 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. 8, the drive circuit board driver circuit design on the 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.
