Problems solved by technology

[0005] Originally, the reset signal was used to insert a black screen to solve the problem of motion blur caused by the hold-type display, but under the condition of increasing the screen update rate, the charging time will be shorter Facing the limit, even if the charging time of the image data is barely extended, the charging time of the reset signal will be insufficient, resulting in invalid charging, and then the target value of the reset signal cannot be reached, and the simulated pulse display (impulse type display) will be discounted, and the phenomenon of dynamic afterimages cannot be effectively improved

Embodiment Construction

[0060] image 3 It is a display device according to an embodiment of the present invention. The display device includes a computing unit 301 , a data reorganization unit 302 , a timing controller 303 and a display panel 304 . The operation of the above-mentioned components will be briefly described below. The calculation unit 301 generates reset data RD according to the input image signal DATA1 and a count relationship related to a plurality of image segments (to be described later). Wherein, the reset data RD can be all black, all white or any single grayscale image data. The data reorganization unit 302 is used for receiving the input image signal DATA1 and the reset data RD, and performing data reorganization on the input image signal DATA1 and the reset data RD to generate the image signal DATA2. The timing controller 303 receives the image signal DATA2 to generate a plurality of control signals CS, and the timing controller 303 transmits the above-mentioned plurality o...

Abstract

The invention provides a display device and a driving method of the display panel. Each line of data wire in the display panel is provided with two sub-data wires. The driving method of the invention comprises the steps as follows: firstly, an input image signal is divided into a plurality of image sections; each image section is provided with display data of pixels which are coupled with two adjacent lines of scanning wires; subsequently, every K image sections are divided into a group; then, a reset data is inserted into the image section of each group so as to form an image signal. The display data of the first group is written in by K times according to a first starting waveform; after a given time of the first starting waveform, the scanning wire corresponding to the first group is driven simultaneously according to a second starting waveform; the reset data is output to the first sub-data wire and the second sub-data wire.

Description

technical field [0001] The present invention relates to a display device and a method for driving a display panel thereof, and in particular to a liquid crystal display device and a method for driving a display panel thereof. Background technique [0002] In order to meet the demand for image quality in the LCD TV market, the application of liquid crystal display panels is gradually moving towards high resolution, impulse system and high frame rate specifications. However, each of the above specifications will affect the charging time which is already a margin, please refer to the following instructions. [0003] figure 1 It is a block diagram of a known double frame rate display system. The display panel 101 of this system is divided into upper and lower halves, and the gate drivers 102, 103 on the left and right sides of the display panel 101 are used to drive the scan lines (not shown) in the display panel 101 to further turn on The pixels (pixels) coupled by the scan ...
