Problems solved by technology

However, the existing liquid crystal display does not take into account the polarity of the driving voltage of the display panel in response to the abnormal image data, which causes the brightness of a part of the display area of ​​the display panel to change instantaneously, resulting in flicker.

Embodiment Construction

[0010] figure 1 is a schematic diagram of a display device according to an embodiment of the present invention. like figure 1 As shown, the display device 100 includes a display panel 110 , a timing controller 120 , a gate driver 130 and a source driver 140 . Wherein, the display device 100 may be, for example, a liquid crystal display (LCD). In addition, the gate driver 130 is electrically connected to the display panel 110 and the timing controller 120 , and the source driver 140 is electrically connected to the display panel 110 and the timing controller 120 .

[0011] The timing controller 120 includes a receiver 121 , and the receiver 121 can generate image data D and a data enable signal DE in response to data and commands from a graphics processing unit (GPU for short). The timing controller 120 can output the image data D to the source driver 140 according to the data enable signal DE. Moreover, the timing controller 120 can also generate a control signal of the ga...

Abstract

A display device includes a display panel and a timing controller is provided. In a first sub-period of the first display period, the display device updates a picture of a first display area in the display panel according to the first polarity control signal. During a second sub-period of the first display period, the display device stops updating a screen of a second display area in the display panel in response to an abnormal event. The time schedule controller divides the second display period into a third sub-period and a fourth sub-period according to the time proportion. And in the thirdsub-period, the display equipment updates the picture of the first display area or stops updating the picture of the first display area according to the second polarity control signal. In the fourthsub-period, the display device updates the picture of the second display area according to the first polarity control signal.

Description

technical field [0001] The present invention relates to a display device, and in particular to a display device including a timing controller. Background technique [0002] For a liquid crystal display (LCD), the electrostatic discharge (ESD for short) phenomenon in the natural environment often interferes with the timing controller in the liquid crystal display. For example, when an ESD event occurs, the timing controller will output abnormal image data, which will cause an abnormal image on the liquid crystal display. In order to avoid the above situation, the existing liquid crystal display does not update the display panel according to abnormal image data. However, the existing liquid crystal display does not take into account the polarity of the driving voltage of the display panel in response to the abnormal image data, which results in the phenomenon of flicker due to the instantaneous change of the brightness of a part of the display area of ​​the display panel. C...
