ＬＥＤ显示屏的视觉效果与所用ＬＥＤ的光参数视角特性有很大关系。为提高可变信息标志的视觉效果 ,保证产品质量 ,需对大量封装的ＬＥＤ管进行光参数的检测分档 ,工作量十分巨大。用现有的ＬＥＤ光电参数测量仪测量视角特性参数时 ,须逐个手动定位测量 ,速度很慢 ,不能满足生
The visual effect of the LED display has a lot to do with the optical parametric viewing characteristics of the LEDs used. In order to improve the visual effect of the variable information sign and ensure the product quality, a large amount of workload is required for detecting and detecting optical parameters of a large number of packaged LED tubes. When measuring the viewing angle characteristic parameters with the existing LED photoelectric parameter measuring instrument, the measurement must be manually positioned one by one, and the measurement speed is very slow.
