基于STN -LCD显示的双折射干涉原理并结合人眼视觉系统因素 ,从理论上说明了液晶盒间隙的不均匀性与STN -LCD显示出现彩虹的关系 ,进而阐述了ITO玻璃基板的表面形貌特征对STN -LCD显示特性的影响。实践表明 :致使STN -LCD出现彩虹的主要因素取决于其制造工艺的控制
Based on the birefringence interference principle of STN-LCD and the human visual system, the relationship between the inhomogeneity of the cell gap and the rainbow appears in the STN-LCD is explained theoretically. Then the surface morphology of the ITO glass substrate is described Effect of characteristics on STN-LCD display characteristics. Practice shows that the main factors that cause rainbow in STN-LCD are the control of its manufacturing process
