【摘要】：为了改善手机液晶显示屏白画面主观偏色的问题,本文运用了色度分析仪测量系统,对手机液晶显示屏白画面偏色矫正方法进行了研究。首先,分析了影响手机液晶显示屏白画面偏色的主要的原因,基于成本的考量,只进行后期模组段的色温矫正,借助设备厂商的色度分析仪测量手机液晶显示屏出厂时的白点坐标的分布范围,对比分析了色坐标优先(方案一)和亮度优先(方案二)两种色温矫正的方法。实验结果表明:方案一可以做到色坐标公差在±0.01以内,甚至更小(看算法的需要和设备的精度),但是无法应用于工程生产领域。方案二虽然牺牲了色温的一致性(±0.015),工厂的生产效率相比方案一提高了两倍多。综合考量成本和工厂生产效率的因素,方案二更好地满足了实际工程应用的需求。
[Abstract]:In order to improve the subjective color deviation of the white screen of the liquid crystal display (LCD) of mobile phone, the method of correcting the color deviation of the white screen of the liquid crystal display screen of the mobile phone is studied by using the colorimetric analyzer. First of all, it analyzes the main reasons that affect the white screen color deviation of the mobile LCD screen. Based on the consideration of cost, only the color temperature correction of the later module segment is carried out. By means of the chrominance analyzer of the equipment manufacturer to measure the distribution range of the white point coordinate when the liquid crystal display screen of the mobile phone leaves the factory, the two methods of color coordinate priority (scheme 1) and brightness priority (scheme 2) are compared and analyzed. The experimental results show that the first scheme can achieve the tolerance of color coordinates within 卤0.01 or even smaller (see the need of the algorithm and the accuracy of the equipment, but can not be used in the field of engineering production. Although the second scheme sacrificed the consistency of color temperature (卤0.015), the production efficiency of the plant was more than twice as high as that of the first scheme. Considering the factors of cost and production efficiency, the second scheme can better meet the needs of practical engineering applications.
