Description

像素充电方法及显示装置 技术领域
本发明涉及显示技术领域，尤其涉及一种像素充电方法及显示装置。
 背景技术
液晶显示器(Liquid Crystal Display, LCD)是一种常用的电子设备，由于其具有功耗低、体积小、重量轻等特点，因此倍受用户的青睐。目前的液晶显示器主要是以薄膜晶体管(Thin Film Transistor,TFT)液晶显示器为主。
液晶显示面板技术是基于施加到液晶分子的电压而旋转特定角度的显示技术。通过改变施加在液晶分子两端的驱动电压，使液晶分子产生相应的转动，使得来自背光单元所产生的光源的光的行进方向改变，可通过液晶分子的不同转动角度来在位于液晶层之上的红、绿、蓝色滤光片处呈现不同的灰阶亮度。通过组合具有不同灰阶亮度的红、蓝、绿三种子像素显示点，可形成不同色彩变化的单一像素显示点。
液晶分子的特性在于，如果施加到液晶分子的驱动电压的极性一直不变，则会导致液晶分子的破坏而无法恢复。因此，在保持液晶分子的两端的驱动电压的电压值不变的情况下，需要每隔一段时间将驱动电压的电压极性反转。即，将相对于公共电极的驱动电压的正电压极性和负电压极性进行极性互换。这里，驱动电压的极性的正负是相对于液晶面板的公共电极的，当像素电极的电压高于公共电极的电压时，称为正极性，当像素电极的电压低于公共电极的电压时，称为负极性。无论像素电极的电压是正极性还是负极性，只要电压绝对值相等，就会具有相同的灰阶亮度。因此，当像素电极的电压与公共电压的电平差的绝对值固定时，无论像素电极的电压极性为正极性还是负极性，像素所表现的灰阶亮度是相同的，但是液晶分子的转向方向相反，从而避免了液晶分子一直固定为相同方向而造成的特性破坏。现有的极性反转方式包括帧极性反转(Frame inversion)、行/列极性反转 (Row/Column inversion)和点极性反转(Dot inversion)等方式。
对于液晶显示面板，尺寸越大解析度越高，但是由于数据线以及信号线部分为金属存在电阻，传递给液晶显示面板远端像素的电压小于近端像素的电压，即越是远端的像素越是充不满像素电压，从而导致液晶显示面板显示亮度不均匀、闪屏等问题，现有技术可以解决同一极性情况下，灰阶变化造成的亮度不均的问题，但是对于极性发生切换时的亮度不均问题，不能进行有效的改善。
综上所述，现有显示面板存在因信号传输线延迟导致显示亮度不均的问题。故，有必要提供一种像素充电方法及显示装置来改善这一缺陷。

在本实施例中，现有的极性反转方式包括帧反转、行反转、列反转以及点反转。沿数据线信号传输方向，当所述像素的极性反转方式为列反转时，在一帧时间内，同一条数据线上的像素均为同一极性，所述像素只发生灰阶变化；当所述像素发生除开列反转意外其他方式的反转时，在一帧时间内，所述像素的极性以及灰阶均发生变化。
在本实施例中，沿数据线信号传输方向，当从第n-1行扫描至第n行时，所述图像数据只发生灰阶变化，所述灰阶补偿器通过所述灰阶补偿数据表计算所述灰阶补偿值，其中，n≥2。
在本实施例中，沿数据线信号传输方向，当从第n-1行扫描至第n行时，所述图像数据发生极性变化，所述灰阶补偿器通过所述极性补偿数据表计算所述灰阶补偿值，其中，n≥2。
本揭示实施例通过建立补偿数据表，包括灰阶补偿数据表以及极性补偿数据表，根据显示面板像素的极性反转方式以及图像数据，当所述像素只有灰阶发生变化时，通过灰阶补偿数据表计算所述灰阶补偿值；当所述像素的极性以及灰阶均发生变化时，通过极性补偿数据表计算所述灰阶补偿值，再对所述像素进行灰阶补偿，从而在不改变像素充电时间的情况下，使像素达到相应的显示画素电压，提升了显示面板像素的充电速率以及显示亮度的均一性，有效解决显示面板存在因信号传输线延迟导致显示亮度不均的问题。
综上所述，虽然本揭示以优选实施例揭露如上，但上述优选实施例并非用以限制本揭示，本领域的普通技术人员，在不脱离本揭示的精神和范围内，均可作各种更动与润饰，因此本揭示的保护范围以权利要求界定的范围为基准。
