Problems solved by technology

[0006] During the actual use of the liquid crystal display device, there will be various interferences, which will cause glitches in the video data signal transmitted to the timing controller, or the sudden disappearance of the video data, resulting in abnormal display of the liquid crystal display device
The existing timing controller has limited ability to deal with abnormal video data, and the quality of the product is low

Embodiment Construction

[0032] In order to further illustrate the technical means adopted by the present invention and its effects, the following describes in detail in conjunction with preferred embodiments of the present invention and accompanying drawings.

[0033] see Figure 1 to Figure 3 , the present invention provides a timing controller, comprising a storage module 10, an enable signal regeneration module 20 electrically connected to the storage module 10, and a selection output electrically connected to the storage module 10 and the enable signal regeneration module 20 Module 30.

[0034] The storage module 10 receives the input enable signal de1 and the video data data data. The enabling signal regenerating module 20 receives the input enabling signal de1 , outputs the conversion enabling signal de2 to the storage module 10 and outputs the control signal ctrl to the selection output module 30 . The selection output module 30 accesses empty data data0.

[0035] see figure 2 and image...

Abstract

The invention provides a time sequence controller and a display device. The time sequence controller comprises a storage module, an enabling signal reproduction module and a selective output module. The time sequence controller detects an input enabling signal through using the enabling signal reproduction module, and produces a converted enabling signal the burr-free waveform to serve as a read enable of the storage module, thereby being capable of eliminating display picture anomalies brought by the existence of burrs of the input enabling signal. Meanwhile, if there is no effective video input within a preset time, the enabling signal reproduction module controls the selective output module to output empty data, thereby being capable of eliminating display picture anomalies caused by sudden disappearance of video data.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a timing controller and a display device. Background technique [0002] With the development of display technology, liquid crystal displays (Liquid Crystal Display, LCD) and other flat display devices are widely used in mobile phones, televisions, personal Various consumer electronic products such as digital assistants, digital cameras, notebook computers, and desktop computers have become the mainstream of display devices. [0003] Most of the liquid crystal displays currently on the market are backlight liquid crystal displays including a liquid crystal panel and a backlight module. The working principle of the liquid crystal panel is to pour liquid crystal molecules between the thin film transistor array substrate (Thin FilmTransistor Array Substrate, TFT Array Substrate) and the color filter substrate (Color Filter, CF), and apply a driving voltage on the two substrates to ...
