Title
(EN) Display driving method and liquid crystal display device
(ZH) 显示驱动方法及液晶显示装置
Abstract
(EN)
The invention provides a display driving method and a liquid crystal display device. The display driving method includes the following steps: providing a liquid crystal display panel which includes multiple sub pixels arranged in an array, and setting every two adjacent sub pixels of the same color in the liquid crystal display panel as a display unit; acquiring the original gray scale value of each display unit, and processing the original gray scale value of each display unit to generate a first display gray scale value and a second display gray scale value of each display unit, wherein thefirst display gray scale value is larger than the second display gray scale value; and driving the two sub pixels in each display unit to display by the first display gray scale value and the second display gray scale value of each display unit, and making one of any two adjacent sub pixels in the liquid crystal display panel driven by the first display gray scale value of the corresponding display unit and the other driven by the second display gray scale value of the corresponding display unit. The chroma visual angle of the liquid crystal display panel can be improved.
