How to solve the inconsistency LED performance parameters, there are two main technologies industry ways: First, by further subdivision of LED specifications to improve the consistency of the performance of LED; the second is through a subsequent correction of ways to improve the display uniformity. Follow-up correction correction from earlier modules, the module calibration, development of today's by-point correction. Correction from simple light intensity correction, full color led display, developed to coordinate correcting color intensity. However, we believe that the subsequent correction is not a panacea. Among them, what is the trip computer display, the optical axis of inconsistency, the light intensity distribution curve is inconsistent, inconsistent attenuation characteristics, poor accuracy and assembly design is not standardized, can not be eliminated by a subsequent correction, led display repair, even such follow-up correction makes optical axis, attenuation, inconsistencies assembling accuracy worsened. We talked about a lot of the above LED failure is usually routine inspection and testing of the LED can not be found. In addition to electrostatic discharge, large current (caused by excessive junction temperature), the improper use of an external force, etc., many LED failure at high temperatures, low temperatures, rapid changes in temperature or other adverse conditions, the display, since the LED chip, an epoxy differences in thermal expansion coefficients of the resin, the stent, the inner lead, solid crystal plastic, PPA cup, etc., caused by different internal stresses generated, therefore, quality testing LED is a very complex task. Trip computer display is what, display, Gao Jin photoelectric provided by Jinan Optoelectronics Technology Co., Ltd. Gao Jin. Jinan Gao Jin Optoelectronics Technology Co., Ltd.
