Description

一种侦测异常画面的色偏补偿方法及显示装置
技术领域
本申请涉及电子技术领域，尤其涉及一种侦测异常画面的色偏补偿方法及显示装置。
背景技术
现如今，显示面板普遍用于数字型钟表、电视机以及便携式计算机等电子产品中，其可以包括液晶显示面板、OLED显示面板等，而一般的显示面板在使用过程中普遍存在一定的色偏现象。例如，目前的液晶显示面板主要是以薄膜晶体管液晶显示面板（Thin Film Transistor-LCD ，简称TFT-LCD）为主，TFT液晶显示面板属于有源矩阵液晶显示面板，它的每一液晶像素点都是由集成在其后的薄膜晶体管来驱动的，从而可以做到高速度、高亮度、高对比度地显示屏幕信息。TFT液晶显示面板的每个像素都设有一个半导体开关，每个像素都可以通过点脉冲直接控制，因而每个节点都相对独立，并可以连续控制。TFT象素架构中的彩色滤光镜依据颜色可分为红（R）、绿（G）、蓝（B）三种，并依次排列在玻璃基板上组成一列，一个象素中的每一个单色滤光镜称之为亚象素（sub-pixel）。TFT液晶显示器包括由三倍门电路信号线（tri-gate）架构的面板，该面板可划分为多个显示区域，每个显示区域对应多列行存储空间，所述行存储空间用于对应地存储子像素点的子像素值。
TFT液晶显示面板在进行像素显示矩阵设计的时候，需要在驱动集成电路的压合区进行集中布线处理，然后再输出到各显示走线。若同时对各显示走线上的子像素点进行充电，显示走线上的两侧电压就会比中间电压迟滞严重，使得每条显示走线上的充电时间不一致，即显示走线上的子像素点不能够在同一时间内达到理想电位。在TFT液晶显示面板的混色画面显示过程中，两侧就会出现严重的色偏问题，表现为偏红、偏绿或者偏蓝。目前针对色偏问题，人们主要采用色偏补偿（CSC）算法对液晶显示器两侧的显示数据进行补偿，使得两侧显示颜色跟中间显示颜色达到一致的效果。但是，因为TFT液晶显示面板的设计架构的原因，在某些情况下，若对该显示画面进行某些功能补偿（如CSC补偿等），容易出现噪点，从而使得画面显示更为糟糕。

应当理解，当在本说明书和所附权利要求书中使用时，术语“包括”和“包含”指示所描述特征、整体、步骤、操作、元素和/或组件的存在，但并不排除一个或多个其它特征、整体、步骤、操作、元素、组件和/或其集合的存在或添加。
还应当理解，在此本申请说明书中所使用的术语仅仅是出于描述特定实施例的目的而并不意在限制本申请。如在本申请说明书和所附权利要求书中所使用的那样，除非上下文清楚地指明其它情况，否则单数形式的“一”、“一个”及“该”意在包括复数形式。还应当进一步理解，在本申请说明书和所附权利要求书中使用的术语“和/ 或”是指相关联列出的项中的一个或多个的任何组合以及所有可能组合，并且包括这些组合。
目前，人们主要采用色偏补偿（CSC）算法对液晶显示器两侧的显示数据进行补偿，使得两侧显示颜色跟中间显示颜色达到一致的效果。其中色偏补偿是指，可将目标子像素点实时施加的电压值调整至标准的电压值，从而改变该目标子像素点显示的颜色，从而解决因阻抗差异导致的液晶显示面板的色偏问题，提高显示效果。同时，为了避免侦测到无画面时使用色偏补偿造成的噪点，需使用以下方法进行相应的调整。其中，无画面包括子像素亮暗画面，子像素亮暗画面即为sub-pixel on/off画面。
参见图1，是本申请实施例提供一种侦测异常画面的色偏补偿方法的示意流程图，如图所示的方法可包括以下步骤:
步骤S101，将输入的n个子像素值逐一预存到一行存储空间中，其中n为大于或等于4的整数。
其中，以TFT液晶显示器中为例， TFT液晶显示器中的TFT象素架构是指，彩色滤光镜依据颜色分为红（R）、绿（G）、蓝（B）三种，并依次排列在玻璃基板上组成一列，一个象素中的每一个单色滤光镜称之为亚象素（sub-pixel）。故将输入的n个子像素值按输入顺序逐一存储到列队形式的像素缓冲器中，像素缓冲器包括若干行存储空间，每行行存储空间可以依次上下并列，每行行存储空间都对应有相应的寄存地址。当然，彩色滤光镜的颜色还可以根据实际情况分为多种其他的颜色。
参见图2a，为一个子像素亮暗画面，图中的每一列代表一列子像素点，每一列中的一个小框则代表一个子像素点，每一个子像素点都对应有一个子像素值，每一个像素值均按顺序逐一寄存到行存储空间对应的地址中。图中的白色即表明该子像素点是亮的，黑色即表明该子像素点是暗的，即正常情况下，子像素点只有暗和亮两种情况。
参见图2b，为行存储空间的寄存地址，其中行存储空间中的地址1（adr1）、地址2（adr2）、地址3（adr3）、地址4（adr4）、···、地址（n-1）（adr（n-1））以及地址n（adrn）中均对应的存有一个子像素值，其中n为大于或等于4的整数。
步骤S102，判断每两个相间隔的子像素值是否均相同。
例如，可以判断adr1与adr3对应的两个子像素值、adr2与adr4对应的两个子像素值、adr3与adr5对应的两个子像素值、···、adr（n-1）与adr（n+1）对应的两个子像素值以及adrn与adr（n+2）对应的两个子像素值是否均相等。
步骤S103，若每两个相间隔的子像素值存在不同，启动色偏补偿。
其中，只要有两个相间隔的子像素值存在不同，则表明TFT液晶显示器显示的不是子像素亮暗画面，即是处于有画面的情况，故此时为了避免色差，需要启动色偏补偿。具体的可以是adr1与adr3对应的两个子像素值不同，也可以是adrn与adr（n+2）对应的两个子像素值不同，还可以是这两种情况同时存在，还可以是所有的每两个相间隔的子像素值都不同。
步骤S104，若每两个相间隔的子像素值均相同，判断每两个相邻的子像素值是否均不相同。
其中，当每两个相间隔的子像素值均相同，即adr1与adr3对应的两个子像素值相同、adr2与adr4对应的两个子像素值相同、adr3与adr5对应的两个子像素值相同、···、adr（n-1）与（n+1）对应的两个子像素值相同、adrn与adr（n+2）对应的两个子像素值也相同时，判断每两个相邻的子像素值是否均不相同。
步骤S105，若每两个相邻的子像素值均不相同，判断当前行存储空间中的每个子像素值与每个子像素值在上一行行存储空间中对应的子像素值是否均不相同。
其中，若adr1与adr2对应的两个子像素值不相同、adr2与adr3对应的两个子像素值不相同、adr3与adr4对应的两个子像素值不相同、···、adr（n-1）与adrn对应的两个子像素值不相同、adrn与adr（n+1）对应的两个子像素值也不相同，那么则可以判断当前行存储空间中的每个子像素值与每个子像素值在上一行行存储空间中对应的子像素值是否均不相同。
作为可选的，若每两个相邻的子像素值存在相同，则返回步骤S103，启动色偏补偿。具体的，只要有adrn与adr（n+1）对应的两个子像素值存在相同，其中n为大于或等于4的整数中的任一个数，那么则表明TFT液晶显示器显示的不是子像素亮暗画面，即是处于有画面的情况，故此时为了避免色差，需要启动色偏补偿。
步骤S106，若当前行存储空间中的每个子像素值与每个子像素值在上一行行存储空间中对应的子像素值均不相同，不启动色偏补偿。
其中，如图2a和图2b所示，若adr1与adr1′对应的两个子像素值不相同、adr2与adr2′对应的两个子像素值不相同、adr3与adr3′对应的两个子像素值不相同、···、adrn与adrn′对应的两个子像素值也不相同，那么则表明TFT液晶显示器显示的是子像素亮暗画面，即是处于无画面的情况，故此时为了避免启动色偏补偿后显示画面会产生噪点等负面影响，则不需要启动色偏补偿，以提高显示画面的显示质量，提升用户的体验度。
作为可选的，若当前行存储空间中的每个子像素值与其在上一行行存储空间中相应的子像素值存在相同，则返回步骤S103，启动色偏补偿。其中，只要有adrn与adrn′对应的两个子像素值相同，n为大于或等于4的整数中的任一个数，那么则表明TFT液晶显示器显示的不是子像素亮暗画面，即是处于有画面的情况，故此时为了避免色差，需要启动色偏补偿。
参见图3，是本申请另一实施例提供一种侦测异常画面的色偏补偿方法的示意流程图，如图所示的方法可包括以下步骤：
步骤S201，将输入的n个子像素值逐一预存到一行存储空间中，其中n为大于或等于4的整数。
步骤S202，判断每两个相间隔的子像素值是否均相同。
步骤S203，若每两个相间隔的子像素值存在不同，启动色偏补偿。
步骤S204，若每两个相间隔的子像素值均相同，判断每两个相邻的子像素值是否均不相同。
步骤S205，若每两个相邻的子像素值均不相同，判断当前行存储空间中的每个子像素值与每个子像素值在上一行行存储空间中对应的子像素值是否均不相同。
步骤S206a，若当前行存储空间中的每个子像素值与每个子像素值在上一行行存储空间中对应的子像素值均不相同，通过计算得到两个相邻的子像素值的绝对差值。
其中，因为即便每个子像素点只有暗和亮两种情况，但是在TFT液晶显示器工作过程中，两个暗的或两个明的子像素点的实时子像素值还是会存在不同。故当前行存储空间中的每个子像素值与每个子像素值在上一行行存储空间中对应的子像素值均不相同时，需要对两个相邻的子像素值进行比较，从而更合理地选择是否进行色偏补偿。
步骤S206b，判断所述绝对差值是否大于预设值。
其中，若两个相邻的子像素点均为暗，但是此时两者的子像素值存在差别，如果以此直接进行色偏补偿，那么则会造成显示画面出现噪点，影响用户的观看效果。故可以设定一个预设值，来进行一定的划分，在合理的基础上，选择是否进行色差补偿。
步骤S206c，若所述绝对差值大于预设值，不启动色偏补偿。
其中，若绝对差值大于预设值，则表明两个相邻的子像素值的差异很大，可以认定为是子像素亮暗画面，即是处于无画面的情况，此时则不需要启动色偏补偿，避免了显示画面产生噪点，提高显示画面的显示质量，提升用户的体验度。
作为可选的，若所述绝对差值小于或等于预设值，启动色偏补偿。
其中，若绝对值小于或等于预设值，则表明两个相邻的子像素值的差异不大，可以认定为不是子像素亮暗画面，即是处于有画面的情况，此时则需要启动色偏补偿，以减少色偏现象的发生，使得用户观看的体验度得到提高。
另外，作为可选的，若当前行存储空间中的每个子像素值与其在上一行行存储空间中相应的像素值存在相同，则返回步骤S203，启动色偏补偿。
