Embodiment Construction

[0038] figure 1 It is a system diagram of a display device according to an embodiment of the present invention. Please refer to figure 1 , in this embodiment, the display device 100 includes a timing controller 110 , a source driver 120 , a scan driver 130 and a display panel 140 . The timing controller 110 receives the display frame signal FDP and is coupled to the source driver 120 and the scan driver 130 . The timing controller 110 provides display data DDP to the source driver 120 according to the received display signal FDP, and provides an output enable signal OE to the scan driver according to the timing of the received display signal FDP. The source driver 120 receives the display data DDP provided by the timing controller 110 to provide a plurality of pixel voltages VP1-VPn to the display panel 140, wherein n is a positive integer. The scan driver 130 receives the output enable signal OE provided by the timing controller 110 to provide a plurality of scan signals G...

Abstract

A display device and a method for driving a display panel thereof. The timing controller of the display device judges whether the display picture signal is a special picture displaying the first gray scale value and the second gray scale value. When the display frame signal is a special frame displaying the first grayscale value and the second grayscale value, the timing controller adjusts multiple enable times of multiple scan signals to control multiple pixels to display the same brightness. When the display image signal is not a special image displaying the first grayscale value and the second grayscale value, the timing controller adjusts the enabling times of the scanning signals to be exactly the same.

Description

technical field [0001] The present invention relates to a display device and its display panel driving method, and in particular to a liquid crystal display device and its liquid crystal display panel driving method. Background technique [0002] With the great progress of optoelectronic technology and semiconductor components, flat panel display devices (flat panel displays), such as liquid crystal display devices (Liquid Crystal Display, LCD), have been rapidly developed and applied to various electronic products. Due to the many advantages of the liquid crystal display device, such as low power consumption, no radiation and high space utilization, the liquid crystal display device has become a mainstream product in the market. [0003] Moreover, with the improvement of the image quality or the improvement of the performance of the display device, the layout of the display panel is also continuously improved. However, when the layout of the display panel changes, the driv...
