液晶显示器的驱动方法、装置及液晶显示器
技术领域
本申请涉及液晶面板显示技术领域，特别涉及一种液晶显示器的驱动方法、装置及液晶显示器。
背景技术
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。
发明内容
本申请提供一种由计算设备执行的驱动液晶显示器的方法，其可降低视角色差，同时可提高面板穿透率并降低背光模组成本。
本申请提出的一种由计算设备执行的驱动液晶显示器的方法，包括以下步骤:

在一实施例中，所述依据每一阵列区块中第一子像素的低电压面板驱动信号计算该阵列区块中驱动发光像素的高亮度和低亮度信号采用如下公式计算：
L= 1*L5+0.8*(L2+L4+L6+L8)+0.4*(L1+L3+L7+L9)；
H=1*H5+0.8*( H2+ H4+ H6+ H8)+0.4*( H1+ H3+ H7+ H9)；
其中， L1、L3、L7、L9表示处于对角位置的四个第一子像素的低电压面板驱动信号；

本申请提出一种液晶显示器的驱动方法。
参照图1，在本申请实施例中，该液晶显示器的驱动方法，包括以下步骤:
S100、将显示面板的第一子像素分成多个阵列区块，选定每一阵列区块中至少一个第一子像素作为发光像素；
S200、接收待显示图像，获取显示面板液晶像素的像素信号，对液晶像素信号进行查表，得到各个像素的第一子像素的高电压面板驱动信号和低电压面板驱动信号；
S300、依据每一阵列区块中第一子像素的高电压面板驱动信号和低电压面板驱动信号分别计算该阵列区块中驱动发光像素的高亮度信号和低亮度信号；
S400、对发光像素采用高亮度信号及低亮度信号依次轮流进行驱动，对其他第一子像素采用像素信号进行驱动。
需要说明的是，现有技术里液晶显示面板驱动信号是由高低电压信号随着图像帧依次轮流驱动。
其中，图2用一帧画面来显示一幅图像，R 表示采用像素信号驱动对应的子像素。
图3和图4表示采用两帧画面显示一幅图像，图3中H表示采用高电压面板信号驱动对应的子像素，图4中L表示采用低电压面板驱动信号驱动对应的子像素。
高电压面板驱动信号 RH /GH/BH与低电压面板驱动信号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，在液晶显示器生产时已经将相关数据烧录至液晶显示器里。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。如此，便得到所需的低电压面板驱动信号及高电压面板驱动信号。
在液晶显示器中，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，背光源的亮度信号不作改变，仅在面板驱动信号作调整。
本申请通过将显示面板的第一像素分成多个区块，多个所述区块阵列排布，在每个区块的同一位置选定至少一个用于进行色差补偿的发光像素；再从接收的图像中获取第一像素的高电压面板驱动信号和低电压面板驱动信号，该高电压面板驱动信号及低电压面板驱动信号是预先设置好的，在需要获取时进行查表即可获得；通过第一子像素的高电压面板驱动信号及低电压面板驱动信号分别计算得到驱动发光像素的高亮度信号及低亮度信号，且对发光像素采用高亮度信号及低亮度信号依次轮流驱动，同一区块内的其他第一子像素则仍采用像素信号进行驱动。通过采用高亮度信号及低亮度信号依次轮流驱动降低了视角色差，此外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。
本实施例中，每一阵列区块中发光像素与其他第一子像素的相对位置相同。
在一实施例中，所述将显示面板第一子像素分成多个阵列区块，选定区块中至少一个第一子像素作为发光像素的步骤包括：
将相邻两个第一子像素为一个区块，选定区块中任意一个第一子像素作为发光像素。
图5及图6中，L表示采用低电压面板驱动信号，H表示采用高电压面板驱动信号，R表示采用像素信号直接驱动。本申请实施例中，同时采用L和H依次轮流对发光像素进行驱动，采用R对显示面板的其他第一子像素进行驱动，用两帧画面显示一幅图像。
这里，在水平方向上相邻两个第一子像素为一个区块，整个显示面板则可分成若干个区块阵列。选定所有区块中同一位置的第一子像素作为发光像素。依据两个子像素的低电压面板驱动信号及高电压面板驱动信号分别计算该发光像素的低亮度信号及高亮度信号。再分别采用低亮度信号、高亮度信号及像素信号对两种类型的像素进行驱动。
在一实施例中，所述将显示面板第一子像素分成多个阵列区块，选定区块中至少一个第一子像素作为发光像素的步骤包括：
将相邻的四个第一子像素作为一个区块，四个第一子像素位于相邻的两行与两列相交处，选定区块中任意一个第一子像素作为发光像素。
图7和图8中，L表示采用低电压面板驱动信号，H表示采用高电压面板驱动信号，R表示采用像素信号直接驱动。本申请实施例中，同时采用L和H依次轮流对发光像素进行驱动，采用R对显示面板的其他第一子像素进行驱动，用两帧画面显示一幅图像。
这里以四个相邻的第一像素作为一个区块，四个第一像素位于一近似的正方形的四个顶点上。选定所有区块中同一位置的第一子像素作为发光像素。依据四个子像素的低电压面板驱动信号、高电压面板驱动信号分别计算该发光像素的低亮度信号及低亮度信号。再分别采用低亮度信号、高亮度信号及像素信号对两种类型的像素进行驱动。
在一实施例中，所述将显示面板第一子像素分成多个阵列区块，选定区块中至少一个第一子像素作为发光像素的步骤包括：
将相邻的九个第一子像素作为一个区块，九个第一子像素位于连续的三行与三列相交处，选定位于区块中心的第一子像素作为发光像素。
图9和图10中，L表示采用低电压面板驱动信号，H表示采用高电压面板驱动信号，R表示采用像素信号直接驱动。本申请实施例中，同时采用L和H依次轮流对发光像素进行驱动，采用R对显示面板的其他第一子像素进行驱动，用两帧画面显示一幅图像。
这里以九个相邻的第一像素作为一个区块，其中八个第一像素位于一近似的正方形的四个顶点及四边上，发光像素位于该正方形的中心位置。选定所有区块中同一位置的第一子像素作为发光像素。依据九个子像素的低电压面板驱动信号及高亮面板驱动信号分别计算该发光像素的低亮度信号及高亮度信号。再分别采用低亮度信号、高亮度信号及像素信号对两种类型的像素进行驱动。
在一实施例中，所述依据同一阵列区块中第一子像素的低电压面板驱动信号计算驱动发光像素的高亮度和低亮度信号采用如下公式计算：
L= 1*L5+0.8*(L2+L4+L6+L8)+0.4*(L1+L3+L7+L9)；
H=1*H5+0.8*( H2+ H4+ H6+ H8)+0.4*( H1+ H3+ H7+ H9)；
其中， L1、L3、L7、L9表示处于对角位置的四个第一子像素的低电压面板驱动信号；
L2、L4、L6、L8表示与处于区块中心位置第一子像素相邻的另外四个第一子像素的低电压面板驱动信号；
H1、H3、H7、H9表示处于对角位置的四个第一子像素的高电压面板驱动信号；
H2、H4、H6、H8表示与处于区块中心位置第一子像素相邻的另外四个第一子像素的高电压面板驱动信号；
L5表示发光像素的低电压面板驱动信号，L表示需要计算的低亮度信号。
H5表示发光像素的高电压面板驱动信号，L表示需要计算的高亮度信号。
参照表图11至图12，表10及表11表示在一个区块中L1~L9及H1~H9的相对位置，图13表示同一区块中所有的第一子像素的低电压面板驱动信号和高电压面板驱动信号与发光像素的低亮度信号及高亮度信号的权重比例系数关系。
需要说明的是，该低亮度信号计算是统计该单位中理论上所有子像素需要给予低电压信号补偿及该单位中个别子像素相应位置的真实位置影响性予以权重调整，使得该低亮度子像素信号得补偿效果可以符合该单位平均所需补偿信号的效果，权重的调整亦反应出该子像素位置真实对应图像需要给予的子像素灰阶信号。
以九个子像素为一个单位举例，取代显示低亮度信号位置的权重给予1,代表实际该位置的影响性是最大，上下左右四个位置的低亮度信号给予次权重0.8，四个角落的低亮度信号给予次权重0.4。
同理，以九个子像素为一个单位举例，取代显示高亮度信号位置的权重给予1，代表实际该位置的影响性是最大，上下左右四个位置的高亮度信号给予次权重0.8，四个角落的高亮度信号给予次权重0.4。
这样即能真实的反应该显示低灰阶位置所应反应的真实代表信号又能给予周围子像素合理的亮度分配。
本申请技术方案为解决TN、OCB及VA 型TFT显示面板的视角色偏缺点，运用直下或侧边背光、白光或RGB三色光源，配合面板高低电压面板驱动信号对背光亮度进行补偿调整，减少面板高低电压驱动信号切换差异造成的闪烁现象。同时还能维持高低液晶电压补偿视角色偏的优点。其次，像素不再设计成主要跟次要像素，大大提伸TFT显示面板的穿透率，减少背光成本的设计。对于高解析度TFT显示面板开发，像素不再作主要及次要像素设计对于穿透率及提伸解析度的效果更为显著。
