Description

显示装置及其显示图像的方法 技术领域
本发明涉及显示技术领域，特别涉及一种显示装置及其显示图像的方法。
 背景技术
传统的TFT-LCD（Thin Film Transistor Liquid Crystal Display，薄膜晶体管液晶显示面板）中往往存在寄生电容Cgd，当栅极线（Gate line）上的电流/电压发生变化时，所述寄生电容Cgd上将会产生电容耦合（Feed Through）电压∆V，使得数据线（Data Line）上的电压进行极性反转时无法以公共电压值Vcom为中值进行对称，这会导致直流残留效应的出现。
在上述直流残留效应的影响下，若所述薄膜晶体管液晶显示面板中的液晶电容的两极板的电压大小长时间保持不变，那么液晶分子中残留的可移动离子会在同一方向的电场中聚集在液晶分子的同一侧，从而形成内电场。
当所述薄膜晶体管液晶显示面板所显示的图像（如图1所示）从高灰阶切换到低灰阶时，所述内电场与所述液晶电容的两极板间的电场相互抵消，使得液晶分子无法偏转到预定角度，最终会导致影像残留（Image Sticking）现象的出现，如图 2所示。
特别地，在用户使用手机、平板电脑、台式电脑等电子产品的过程中，由于上述电子产品的屏幕的部分区域有时会长时间显示一个静态画面，当画面切换时，上述电子产品的屏幕将产生人眼容易识别的影像残留现象。
为减少上述影像残留现象的出现，传统的技术方案是：对用于显示图像的灰阶电压进行非对称调整。
由于传统的显示面板的部分部件或材料的性质（例如，液晶材料的性质）具有时变性（随时间变化而变化的特性），因此，传统的显示面板的最佳公共电压值Vcom会随时间的变化而变化，传统的显示面板的上述部分部件或材料的性质要在开机后较长的时间才能稳定，在这段较长的时间中，如果保持Vcom等不变，那么传统的显示面板所显示的图像的闪烁值将处于不断变化的状态，如图3所示，这会使得所述影像残留现象的明显程度大大增加。
故，有必要提出一种新的技术方案，以解决上述技术问题。
