现有的大尺寸液晶显示面板大多数采用负型VA液晶或IPS液晶技术，VA型液晶技术相较于IPS液晶技术存在较高的生产效率及低制造成本的优势，但光学性质上相较于IPS液晶技术存在较明显的光学性质缺陷，尤其是大尺寸面板在商业应用方面需要较大的视角呈现，VA型液晶驱动在视角色偏往往无法符合市场应用需求，这影响了VA型液晶技术的推广。
一般VA型液晶技术解决视角色偏的方式是将RGB（红色、绿色、蓝色）各基色再划分为主次像素，经空间上主次像素给予不同的驱动电压来解决视角色偏的缺陷，这样的像素设计往往需要再设计金属走线或薄膜晶体管元件来驱动次像素，造成可透光开口区牺牲，影响面板穿透率，直接造成背光模组成本的提升。

本申请提出一种显示装置视角色差补偿方法。
参照图1，在本申请实施例中，该一种显示装置视角色差补偿方法，包括以下步骤；
S100、接收输入的图像，对输入图像每个像素面板驱动信号查表分别得到相邻两帧图像中每个像素的对应第一驱动信号及第二驱动信号。值得说明的是，每组第一驱动信号及第二驱动信号的正视角亮度与对应的输入图像每个像素面板驱动信号的正视角亮度相同，即单独采用的面板驱动信号驱动与采用两种面板驱动信号（高面板驱动信号及低面板驱动信号）所达到的显示亮度相同；
S200、分别计算第一驱动信号的平均值及第二驱动信号的平均值，分别计算同一帧图像中第一驱动信号和第二驱动信号的平均值。需要说明的是，将原图像信号分一帧为第一驱动信号一帧为第二驱动信号，是一般的时序上实现色差补偿的方式是较传统的补偿方式，但容易存在一帧全部为第一驱动信号一帧全部为低电压面板，驱动亮度不对等造成人眼易见闪烁，因此改进为同一帧图像同时存在高电压及低电压像素穿插，次一帧图像同一像素第一驱动信号及第二驱动信号互换，因此分别计算两帧图像中同一帧图像中第一驱动信号和第二驱动信号的平均值。
S300、根据计算的平均值及给定的基准亮度信号，计算所述背光区域的背光模组所需的亮度补偿信号；
S400、根据所述亮度补偿信号，对后续帧图像进行视角色差补偿。本申请是将背光分为多个区块，每个区块含多个高电压及低电压像素，每个区块背光亮度可以独立控制，根据该区块内同一帧图像所包含的第一驱动信号及第二驱动信号对每一帧每个区块进行背光亮度补偿。
本实施例中，第一驱动信号为高电平面板驱动信号，第二驱动信号为第二驱动信号。
需要说明的是，本实施例中，将一幅图像分为两帧图像显示，这两帧图像称为相邻的两帧图像。本申请两帧图像信号中每一帧图像同时存在高低电压信号，液晶显示面板同一像素驱动信号是由高低电压信号随着图像帧依次轮流驱动。第一驱动信号RH/GH/BH与第二驱动信号RL/GL/BL，为事先根据RGB输入信号给予的预设高低电压信号，是依照需要补偿的视角效果所决定，在显示装置生产时已经将相关数据烧录至显示装置里。一般是以LUT（Look Up Table，显示查找表）的方式记录在硬件缓冲器里面，以8 bit驱动信号来看每一R/G/B输入信号输入0 ～255共对应256高低电压信号，共有 3*256对高电压信号RH/GH/BH与低电压信号RL/GL/BL。
在显示装置中，液晶的显示效果是由面板驱动信号及背光源的亮度信号共同驱动来决定的。
本实施例中，根据计算的到的平均值及给定的基准亮度信号，计算得到所需的亮度补偿信号，使得显示装置在基准亮度信号、第一驱动信号及第二驱动信号配合下，显示装置呈现的显示效果与在亮度补偿信号、第一驱动信号及第二驱动信号共同配合驱动下的显示效果一致。
本申请通过接受输入的图像，接收输入的图像，对输入图像每个像素面板驱动信号查表分别得到相邻两帧图像中每个像素的对应第一驱动信号及第二驱动信号，使得每组第一驱动信号及第二驱动信号的正视角亮度与对应的输入图像每个像素面板驱动信号的正视角亮度相同。分别计算第一驱动信号的平均值及第二驱动信号的平均值，计算一帧图像中第一驱动信号和第二驱动信号的平均值，并计算另一帧图像中第一驱动信号和第二驱动信号的平均值。通过计算的这些平均值和给定的基准亮度信号，再计算得到亮度补偿信号，再将亮度补偿信号输入至背光模块对应的区域，实现对视角色差补偿。本申请技术方案无需在面板上设置主次像素，从而无需设计金属走线和薄膜晶体管元件来驱动次像素，简化了生产工艺，降低了成本，同时由于去掉了次像素，提高了面板的穿透率。
