Embodiment Construction

[0014] In order to explain in detail the technical content, structural features, achieved goals and effects of the technical solution, the following will be described in detail in conjunction with specific embodiments and accompanying drawings.

[0015] see figure 1 , figure 1 It is a timing diagram of Demux, such as figure 1 As shown, the falling edge of Demux_R to the falling edge of Gate is the time for the Data Line that transmits sub-pixel R data in the Demux LCD screen to charge the Pixel electrode. Here, this time is named R-1. For the R sub-pixel, The charging time R-1 of the Data Line to the Pixel electrode is sufficient, so the display brightness of the R sub-pixel will not be affected; the falling edge of Demux_G to the falling edge of Gate is the Data for transmitting sub-pixel G data in the Demux LCD screen The charging time of Line to Pixel electrode, here this time is named G-1, for G sub-pixel, the charging time G-1 of Data Line to Pixel electrode is enough, ...

Abstract

A Demux driving method, comprising the steps of, in the enabling time domain of the gate drive line, being divided into the initial Demux driving stage of the first sub-pixel, the initial Demux driving stage of the second sub-pixel, and the Demux driving stage of the third sub-pixel The driving phase, the first sub-pixel's re-Demux driving phase, the second sub-pixel's re-Demux driving phase, the first sub-pixel's initial Demux driving phase and the first sub-pixel's re-Demux driving phase are located in the third sub-pixel The Demux driving stage of the second sub-pixel is set before and after the Demux driving stage of the second sub-pixel, and the Demux driving stage of the second sub-pixel is respectively set before and after the Demux driving stage of the third sub-pixel. Different from the existing technology, the above technical solution sets the time domain of the third sub-pixel in the middle of the secondary driving of other sub-pixels, thereby ensuring that the third sub-pixel has enough charging time, and finally achieves the solution to the insufficient charging of sub-pixels. question.

Description

technical field [0001] The invention relates to the field of Demux driving, in particular to a design of a Demux driving method. Background technique [0002] For LCD screens, the charging rate of the Demux LCD screen is not good, especially the charging rate of the blue sub-pixel B will be much lower than that of the ordinary one, which will affect the display effect of the Demux LCD screen. This solution is specially designed for this phenomenon. A problem of improving the sub-pixel charging rate. Contents of the invention [0003] Therefore, it is necessary to provide a new special timing sequence of Demux to avoid the color mixing problem. [0004] In order to achieve the above object, the inventor provides a Demux driving method, including the following steps, in the enable time domain of the gate drive line, it is divided into the initial Demux driving stage of the first sub-pixel, the initial Demux driving stage of the second sub-pixel The driving stage, the Demux...
