|
摘要
本文通过对LGP线性增加载荷的耐磨实验,进行了相关的交叉对比实验验证,研究了LGP网面耐磨性、反射片材质、反射片粗糙度3个因子对LCDLGP网面点伤类白点的影响,结果表明LGP耐磨性越高,LCDLGP网面点伤类白点不良率越少,当LGP耐磨性达到400g以上时,可使点伤类白点不良率降低到0.046%。PP材质反射片和PET材质反射片相比,选用PP材质反射点伤类白点更少。反射粗糙度越低,点伤类白点不良率越少,当PP材质反射粗糙度到0.60Ra/um时,LCD LGP网面点伤类白点不良率可以降低到0.033%。
In this paper, the wear resistance of the LGP mesh surface, the material of the reflector and the roughness of the reflector on the white spot of the LCD LGP net surface are studied by the wearresisting experiment of the LGP linear increasing load and the related cross-contrast experiment. The results show that the higher the wear resistance of LGP is, the less the defect rate of white spot on,LCD LGP surface is. When the wear resistance of LGP is more than 400 g, the defect rate of spot injury can be reduced to that of 0.046%.PP reflector and PET reflector. The use of PP material reflection point injury-like white spots less. The lower the reflection roughness, the point The less the defect rate of white spots is, the lower the defect rate of white spots of, LCD LGP mesh can be reduced to 0.033%when the reflection roughness of PP material reaches 0.60 Ra/um, and the defect rate of white spots of,LCD LGP mesh surface can be reduced to 0.033%.
