A driving method, driving device and display device of a display panel

Abstract

The embodiment of the invention discloses a driving method, a driving device and a display device of a display panel. The driving method comprises forming a sub-pixel group of 2n rows of sub-pixels in the display panel, forming a first sub-pixel group of odd-numbered rows of sub-pixels in the sub-pixel group, and forming a second sub-pixel group of even-numbered rows of sub-pixels; for 2n rows of sub-pixels A sub-pixel group composed of pixels first drives the pixels of the first sub-pixel group for display; then drives the sub-pixels of the second sub-pixel group for display; the display panel includes a plurality of pixel units arranged in an array; each pixel unit includes at least The sub-pixels of three colors, the sub-pixels of each color include first-type sub-pixels and second-type sub-pixels; the first-type sub-pixels and second-type sub-pixels are arranged at intervals along the row direction and column direction where the pixel units are arranged , the level of the data signal provided by the drive module is different. Through the technical scheme of the invention, the working frequency of the driving module and the power consumption of the driving module are reduced.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a driving method, a driving device and a display device of a display panel. Background technique [0002] With the development of liquid crystal display panels, large viewing angle and low cost have become important indicators for measuring liquid crystal display panels. Among the various technologies for reducing the cost of liquid crystal display panels, the tri-gate technology has been widely used due to its faster data transmission speed. Using the tri-gate technology can shorten the charging time of the pixel electrode to 1 of the original charging time. / 3, correspondingly, the operating frequency of the drive module that provides the data signal is tripled. [0003] For the realization of the wide viewing angle of the liquid crystal display panel, gamma correction is generally used to process the pixel units in the liquid crystal display panel....

AI Technical Summary

Problems solved by technology

[0004] Comprehensively realize the low-cost tri-gate technology and the gamma correction technology for wide viewing angle. The tri-gate technology itself has increased the operating frequency of the drive module. In addition, the gamma-corrected sub-pixel and its adjacent sub-pixels The level of the data signal is different, which greatly increases the level jump frequency of the data signal provided by the drive module, increases the power consumption of the drive module providing the data signal, and may even burn the drive module in severe cases
