基于前光模组的反射式液晶显示视角
Viewing angle of reflective liquid crystal display based on front light module
摘要
Abstract
Reflective liquid crystal display(LCD)has the advantages of low power consumption and green environmental protection.However,due to the lack of optical films such as brightness enhancement film to modulate the viewing angle,the viewing angle curve under the common dot morphology has problems such as jump and unevenness.In order to improve the viewing angle of reflective liquid crystal display,a simulation model of reflective liquid crystal module is established to explore.Firstly,the viewing angle problems of the front light module are analyzed.Then,the influence of the dot morphology of the dots on the viewing angle is analyzed by taking the conical and truncated cone dots as examples.The prismatic dots are proposed to improve the viewing angle.The simulation results show that the prismatic dots can effectively solve the problem of±35° angle curve jumping and unevenness perpendicular to the direction of incident light,and the brightness of the center of the viewing angle is increased by 52.3%compared with the conical dot.This study has important reference significance for the perspective design of reflective liquid crystal display devices.关键词
