How to solve the LED performance parameters of inconsistency, led screen, 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 by way of a subsequent correction to improve the uniformity of the display. Follow-up correction correction from earlier modules, the module calibration, development of today's by-point correction. Correction from simple light intensity correction, color coordinate the development of light intensity correction. However, led light word, we think the subsequent correction is not a panacea. Wherein the optical axis is inconsistent, 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, even this correction will follow the optical axis, attenuation, assembled precision inconsistencies worsened. The working environment due to the use of different display operating conditions vary. In terms of the environment, indoor temperature difference is small, indoor led display, no snow and the effects of ultraviolet radiation; outdoor temperature difference of up to 70 degrees, plus wind and rain. Harsh environment will exacerbate the aging of the display, the work environment is an important factor affecting the life of the display. led screen _led_ Gao Jin photoelectric provided by Jinan Optoelectronics Technology Co., Ltd.
