Embodiment Construction

[0028] The present invention provides a flat panel display and its driving method. By changing the order of low grayscale values ​​and high grayscale values ​​in the super pulse driving method, the flat panel display can not only maintain the overall average brightness of the pixels in the super pulse driving mode, but also It can also solve the problem of image screen flickering.

[0029] refer to figure 1 , which is a block diagram of a flat panel display according to a preferred embodiment of the present invention. The flat panel display 100 , such as a liquid crystal display, includes a pixel array 110 , a data driving unit 120 and a scanning driving unit 130 . The pixel array 110 has a plurality of pixels (not shown), and these pixels at least include first pixels and second pixels. The first pixel and the second pixel may or may not be adjacent to each other. The data driving unit 120 is used to drive the pixels, and the scan driving unit 130 is used to enable the pix...

Abstract

The invention relates to a two-dimensional display and a drive method thereof. The two-dimensional display is provided with a plurality of pixels which at least comprise a first pixel and a second pixel. The drive method for the two-dimensional display comprises the following steps of: driving the first pixel according to a first grey value in a first subframe period of a frame period and drivingthe second pixel according to a second grey value; and driving the first pixel according to a third grey value in a second subframe period of the frame period and driving the second pixel according to a fourth grey value, wherein the first grey value is less than the third grey value; the average value of the first grey value and the third grey value is equal to a first target grey value; the second grey value is more than the fourth grey value; and the average value of the second grey value and the fourth grey value is equal to a second target grey value.

Description

technical field [0001] The present invention relates to a flat display and its driving method, and in particular to a flat display capable of solving the flickering problem of image frames and its driving method. Background technique [0002] For liquid crystal displays, solving the problem of motion blur caused by adopting a hold type driving method has been a subject that various companies have been striving for in recent years. Among them, the impulse-driving method is a solution that has been developed for many years. [0003] The pulse driving method is to periodically insert a black picture during each frame period of the dynamic image, so it can effectively reduce the time for the image of the previous frame period to stay in the human eye, thereby alleviating the blurring problem of the dynamic image. However, due to the insertion of a black screen, the light transmission time during each frame period is shortened, so the pulse-driven liquid crystal display, althoug...
