Description

一种时间混色专用BLU
技术领域
本发明涉及一种液晶屏，具体涉及一种时间混色专用BLU。
背景技术
随着人们生活水平的提高，无辐射和无闪烁的液晶电视已逐渐成为每个家庭的标配家电。目前液晶电视显示使用的空间混色法。这种方法是利用人眼空间细节分辨力差的特点，将三种基色光在同一平面的对应位置充分靠近，只要三个基色光点足够小且充分近，人眼在离开一定距离处将会感到是三种基色光混合后所具有的颜色。这种空间混色的方法是彩色电视的基础。
发明内容
为了解决上述技术问题，本发明提供了一种时间混色专用BLU，采用时间混色法，利用人眼的视觉惰性（对于中等亮度的光刺激，视觉暂留时间约为0.05至0.2秒，是视网膜上的视神经的反应时间），顺序地让三种基色光出现在同一表面的同一处，人眼会感到这三种基色光是同时出现的，具有三种基色相加后所得颜色的效果。利用此原理：彩色液晶显示可以把背光做成R/G/B三基色光源，液晶OC可以省去彩色滤光膜CF，只通过TFT开关控制三基色光通过的强弱达到混色的效果，降低成本。
本发明采用如下技术方案：一种时间混色专用BLU，包括液晶屏和背光模组，液晶屏的背面为背光模组，所述液晶屏由上至下为上偏光板、玻璃基板一、液晶屏、玻璃基板二和下偏光板，所述背光模组为RGB背光。
所述玻璃基板二上粘附信号电极、走线电极、薄膜晶体管、透明电极。
所述背光模组包括紧凑排列的背光源，背光源与显示屏长宽相同，背光源由R/G/B三基色灯条组成，三基色灯条并列排放。
所述背光源的开关刷新频率180Hz，且间隔时间为1/180 s=0.0056s。
使用原理：R/G/B三基色光源由电源板控制依次打开，且间隔时间为1/180 s=0.0056s，相应液晶屏同步依次打开，同一平面同一点间隔0.0056s显示R/G/B画面，由于视觉惰性，人眼残留影像的时间一般0.05至0.2秒，所以人会感觉R/G/B会同时存在，根据颜色混色原理，会模拟出各种颜色，颜色的亮度信息由TFT晶体管控制液晶翻转所决定，达到彩色显示的效果。
本发明具有的优点：只通过TFT开关控制三基色光通过的强弱达到混色的效果，降低液晶屏成本。
