Embodiment Construction

[0056] 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 reset unit 110 , a timing controller 120 , a source driver 130 , a gate driver 140 and a display panel 150 . The reset unit 110 receives a data enable signal DE and a clock signal CLK. The timing controller 120 receives the data enable signal DE and the clock signal CLK and is coupled to the reset unit 110 . The source driver 130 is coupled to the timing controller 120 and the display panel 150 . The gate driver 140 is coupled to the timing controller 120 and the display panel 150 .

[0057]In this embodiment, the display panel 150 is an example of a dual gate display panel, that is, each pixel column (not shown) of the display panel 150 corresponds to two scanning lines (not shown). At this time, the source driver 130 will separately capture the odd pixel data and the even pixel da...

Abstract

The invention relates to a display device, which comprises a display panel, a resetting unit, a time sequence controller and a source driver, wherein the resetting unit is used for receiving a data enabling signal and a frequency signal, counting according to the frequency signal when the data enabling signal indicates enabling and generating a resetting signal when counting to a default value; the time sequence controller is coupled with the resetting unit and is used for outputting at least one internal frequency signal and at least one control signal and carrying out resetting according tothe resetting signal; and the source driver is coupled with the display panel and the time sequence controller to output a plurality of pixel voltages to the display panel according to the internal frequency signal and the control signal.

Description

technical field [0001] The present invention relates to a display device and its operating method, and in particular to a display device with a reset unit and its operating method. Background technique [0002] With the development of high technology, video products, especially digital video or image devices have become common products in daily life. At present, the most attention-grabbing display is a flat-panel display developed in conjunction with optoelectronic technology and semiconductor manufacturing technology, such as a liquid crystal display (Liquid Crystal Display, LCD). Due to the advantages of low-voltage operation, no radiation scattering, light weight, and small size, liquid crystal displays have become the main subject of display research in recent years. [0003] Generally speaking, there are certain regulations on the power sequence when the liquid crystal display is turned on and off, but in some operating states of the liquid crystal display, the power s...
