Description
Technical Field
The present invention relates to the field of display technologies, and in particular, to a display mode setting method for a liquid crystal panel and a liquid crystal panel.
Background
With the development of Display technology, flat panel Display devices such as Liquid Crystal Displays (LCDs) have advantages of high image quality, power saving, thin body, and wide application range, and thus are widely used in various consumer electronics products such as mobile phones, televisions, personal digital assistants, digital cameras, notebook computers, and desktop computers, and become the mainstream of Display devices.
In the conventional liquid crystal display panel, due to factors such as driving and characteristics of the liquid crystal display panel, displayed white field color coordinates are different to different degrees. For the white field color coordinate difference of the liquid crystal display device, if corresponding white balance adjustment is not performed, the color display effects of different liquid crystal display panels can be greatly different. Therefore, in the production process of the liquid crystal display panel, white balance tracking correction is usually performed, and white balance adjustment is performed on the liquid crystal panels through the white balance lookup table so that the colors displayed by each liquid crystal panel tend to be consistent.
The response speed of liquid crystal has been a problem of the liquid crystal panel that needs to be improved due to the liquid crystal characteristics of the liquid crystal panel. In order to improve the display effect of dynamic images and reduce the dynamic smear phenomenon and response time, the liquid crystal panel often adopts an overdrive technique to shorten the liquid crystal rotation time, so that the display images are quickly converted into target images. In order to realize overdrive, an overdrive lookup table needs to be preset, so that an overdrive gray scale can be found from the overdrive lookup table according to a source gray scale and a target gray scale, and then the liquid crystal is driven to turn over by a driving voltage corresponding to the overdrive gray scale, so that the overdrive is realized.
The response time is crucial to the effect of the display screen playing dynamic pictures. For example, for a live football match or a wonderful fighting picture, a faster response time may be required to obtain a better playing effect. Whereas for some common dramas only a normal response time effect may be required. In fact, when the liquid crystal panel leaves the factory, the response time is fixed, and the response time type cannot be selected according to the content of the video during playing, so as to achieve a better playing effect.

Detailed Description
As shown in table one below, which is a table of response times from different gray levels to different gray levels (17 × 17), the response times corresponding to gray level changes between 17 gray levels, such as 0, 16 … … 240, 255, etc., are shown, and the unit of the response time may be milliseconds. As can be seen from Table one, the response times from 0 to 255 are 11.38 milliseconds and from 0 to 240 are 6.771 milliseconds, with the two response times being very different. Therefore, if the highest gray scale of the panel is set to 240 gray scales, the response time can be increased as a whole, and the highest gray scale displayed by the liquid crystal panel can be changed from 255 to 240 gray scales by setting the white balance. The pixels of the liquid crystal panel are composed of three sub-pixels of RGB, i.e., red, green and blue. Therefore, the response time of the RGB three color sub-pixels are also different respectively. Therefore, the invention can respectively set different response time effects aiming at the RGB three-color sub-pixels, and provides a design method with adjustable response time, which can select different response time modes according to the content of the played video.
