Problems solved by technology
However, the data signals of point-to-point transmission are easily interfered by external signals (radio frequency signal lights) during the transmission process, causing the data driver to fail to decode the data packets, making the decoding of the data packets fail. At this time, the display device cannot display the current frame image and appears continuous Screen flickering and blurring, resulting in a decrease in the quality of the displayed image

Embodiment Construction
[0053]The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
[0054]For existing liquid crystal display devices, the timing controller sends a clock signal to the drive controller, so that the clock signal triggers the data signal stored in the drive controller to use the data signal to charge the thin film transistors included in the array substrate. The deflection direction of the liquid crystal is changed when the transistor is charged, thereby realizing the modulation of the light, so that the liquid ...

The invention discloses a data driver and its method, a timing controller and its method, a display control device and a display device, and relates to the field of display technology to suppress the problems of continuous flickering and blurry display screens caused by signal interference. The data driver includes: a data identification unit and a signal feedback unit; the timing controller includes a second judgment unit and a state adjustment unit. The state of the clock signal is fed back by the signal feedback unit, and the state of the clock signal is adjusted by the state adjustment unit so that the clock signal is in a non-interference state. The data driver and method, timing controller and method, display control device and display device provided by the invention are used in display control.
Description
Technical field[0001]The present invention relates to the field of display technology, in particular to a data driver and method, a timing controller and method, a display control device and a display device.Background technique[0002]The flat panel display devices currently on the market are generally divided into liquid crystal display devices and organic electroluminescence display devices. These flat panel display devices are relatively thin and light, have lower energy consumption and good display effects.[0003]Existing flat panel display devices are mostly based on array substrates to modulate light, so as to realize image display. When the array substrate modulates the light, the timing controller is used to send a clock signal to the data driver, and the clock signal triggers the data signal stored in the data driver, so that the triggered data signal can be used to send the data signal to the corresponding film included in the array substrate. The transistor is charged, so t...
