Problems solved by technology

However, the design of the existing technology often needs to add metal wiring or thin film transistor elements on the display panel to drive the sub-pixels, resulting in a reduction in the area of ​​the light-transmitting area and affecting the light transmittance of the panel.

Embodiment Construction

[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0022] An embodiment of the present invention provides a method for driving a display device. The method includes: dividing a frame of pre-display image into m frames of display images, and each pixel of the pre-display image corresponds to a preset gray scale voltage and a preset brightness;

[0023] In the same display frame of the m frames of display images, the difference between the driving voltage of at least one pixel unit and the corresponding preset gray scale voltage of every n pixel units on the display...

Abstract

The embodiment of the invention discloses a driving method of a display device and a display device. The method includes: dividing a frame of pre-display images into m frames of display images; in the same frame of display images, the driving voltage of at least one pixel unit among every n pixel units on the display panel and the corresponding preset gray scale voltage The polarity of the difference between the driving voltage of other pixel units and the difference between the corresponding preset gray-scale voltage is different; among the m driving voltages of the m-frame display screen of the same pixel unit, at least one is between the corresponding preset gray-scale voltage The polarity of the difference between the difference and other driving voltages and the corresponding preset grayscale voltage is different, and the average brightness of the same pixel unit in the m-frame display screen is equal to the preset brightness; the backlight brightness of each frame display screen in the m-frame display screen The product with the sum of the driving voltages of all the pixel units of the display panel is equal. The embodiments of the present invention improve the viewing angle deviation of the display device and improve the image display quality.

Description

technical field [0001] Embodiments of the present invention relate to liquid crystal display technology, and in particular, to a driving method of a display device and a display device. Background technique [0002] The current large-size LCD panels mostly use Vertical Alignment (VA) liquid crystal technology or In-Plane Switching (IPS) liquid crystal technology. Compared with IPS liquid crystal technology, VA liquid crystal technology has higher production efficiency and lower manufacturing cost. Cost advantage, but the VA liquid crystal display device has a viewing angle deviation at a large viewing angle, which affects the display effect. [0003] In the prior art, in order to solve the viewing angle deviation of the VA liquid crystal display device, each pixel unit of the display panel is usually divided into primary and secondary pixels, and different driving voltages are given to the primary and secondary pixels. However, the designs in the prior art often need to add...
