title: [Influence of sun radiation on optical properties of liquid crystal display device].
abstract: Sunlight affects mainly the light stability and life of liquid crystal display device, which will lead to rapid aging of the device. By measuring the optical properties of liquid crystal display devices radiated with different time by spectrophotometer, the influences of long time sunlight radiation on the optical properties of the device were studied, and the changes of its optical properties were analyzed. The results indicate that structural and optical properties of liquid crystal slices of calculator LCD (B group) and telephone LCD (C group) are similar and the qualities are relatively good, while the aging problem of personal computer LCD (A group) liquid crystal slice is more serious than those of B and C groups, moreover, the qualities of liquid crystal slices in A group are worse. The structural and optical properties of liquid crystal display device will change accordingly after long time sunlight radiation. The surface of liquid crystal display device will become yellow and nigrescent, and the spectrum transmission properties will decline markedly, which is related to liquid crystal materials and manufacturing techniques.
