Description

Technical Field

[0001] The present invention relates to the technical field of pure color picture display of liquid crystal display screens, and in particular to a driving method and circuit of a liquid crystal display panel. Background Art

[0002] If the liquid crystal molecules are always working under a certain fixed voltage, the characteristics of the liquid crystal molecules will solidify. After canceling this fixed voltage, the liquid crystal molecules can no longer respond to other external voltages. Therefore, AC voltage is used to drive the liquid crystal molecules to work in liquid crystal display technology. However, the use of AC voltage alone will cause the display screen to flicker. In order to solve the problem of screen flicker, the driving methods used by existing liquid crystal display panels mainly include point flipping, column flipping, row flipping, etc., so as to achieve the opposite polarity of the driving voltages of adjacent pixels, and use the spatial fusion of the optical response waveforms of adjacent pixels to suppress screen flicker.

[0003] The triple gate driving method is also called the triple-rate driving method. It is a technology used to reduce the number of display driver chips. In the triple gate driving architecture, the red, green and blue sub-pixels are arranged vertically, which is equivalent to sharing one data line for every three columns of sub-pixels. Each row of sub-pixels corresponds to three gate lines. Compared with the traditional sigal-gate architecture, the number of data lines is reduced to one third and the number of gates is increased three times. Although fewer data lines are used, this driving method has the problem of high power consumption when displaying pure color images (i.e. displaying red images / green images / blue images), which reduces battery life.

DETAILED DESCRIPTION

[0019] The following will be combined with the accompanying drawings in the invention to clearly and completely describe the technical solutions in the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, other embodiments obtained by ordinary technicians in this field without creative work are all within the scope of protection of the present invention.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0024] The existing Triple gate driver architecture, such as Figure 1-3 , Figure 1 This is a schematic diagram of the timing of pure color screen driving in the prior art solution. Figure 2 is a schematic diagram of the polarity of the nth frame in the prior art solution, Figure 3 This is the polarity diagram of the n+1th frame in the prior art solution; when displaying a pure color image, the power consumption is high, which affects the battery life of the product. Due to the unique driving method of triple gate, the power consumption of a pure color image is high within a frame. The reason is that the data line undergoes multiple high-level pulses within a frame. Take the red image as an example, that is, G1 is turned on, the data line outputs a high level, G2 is turned on, the data line becomes a low level, G3 is turned on, the data line is still a low level, G4 is turned on, and the data line becomes a high level again, that is, when the M+3th row (M is 0, 1, 2, 3, etc.), the data line is a high level, and the other rows are low levels. Obviously, it has been in the process of high-level pulse conversion within a frame, resulting in high power consumption of the red image.
