摘要
液晶显示设备主要通过时序控制模块结合液晶面板通过滤色片实现空间混色的彩色显示效果,时间混色的场序显示可以实现同样的彩色显示目的。场序显示由于没有滤色片具有高亮度,低功耗的特点。但是,由于传统的一帧时间内不同时间场的色彩信号进行混色会产生色彩分裂现象(color breakup),导致色彩不均匀。本文通过将时序控制模块和背光控制模块进行整合,采用分时控制信号来实现液晶面板像素阵列的单元的逐场逐行显示控制,通过这种分时控制的方式消除传统时间混色显示的color breakup现象,改善图像色彩显示的均匀度。
The liquid crystal display device mainly realizes the color display effect of spatial color mixing through the timing control module combined with the liquid crystal panel by the color filter,and the time-mixed color field sequential display can achieve the same purpose.The field sequential display has the characteristics of high brightness and low power consumption due to no color filter.However,mixing of color signals of different time fields within the time of one conventional frame will result in color unevenness.In this paper,by integrating the timing control module and the backlight control module,the time-sharing control signal is used to realize the field-by-field progressive display control of the pixel array of the liquid crystal panel.The color breakup of the traditional time mixed color display is eliminated and the uniformity of image color display is improved by this time-sharing control method.
