Abstract

The invention provides a display device and a driving method thereof. The display device comprises a first display panel, a second display panel and a driving circuit. The first display panel comprises a plurality of first pixel units capable of displaying colors, and each first pixel unit comprises a plurality of sub-pixel units. The second display panel is arranged on the light emitting side ofthe first display panel and comprises a plurality of second pixel units. The distribution density of the second pixel units is greater than that of the sub-pixel units. Therefore, the second display panel is arranged on the light emitting side of the first display panel, when the first display panel carries out image display, gray-scale dimming can be carried out on the second display panel. Therefore, contrast of the display image of the first display panel is changed, and the contrast of the display image of the display device is improved. In addition, the second display panel with the higher resolution ratio is arranged on the light emitting side of the first display panel, so that the fine and smooth degree of image display can be effectively improved, and the resolution ratio of the display device is improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device and a driving method thereof. Background technique [0002] In recent years, in order to improve the contrast of LCD products, Mini / Micro LED technology has received extensive attention and development. At present, Mini / Micro LED technology is mainly used in backlight technology. With Local Dimming technology, it can effectively improve the display contrast of LCD and greatly improve the effect of product display. However, the timing control of LED driving is a difficult problem in design. If the timing control is improper, it is easy to cause the LED lamp to burn out. [0003] Therefore, how to improve the contrast of the display screen of the display product is still an urgent problem to be solved by those skilled in the art. Contents of the invention [0004] The invention provides a display device and a driving method thereof to improve the contr...
