Driving method and driving device of display panel and display device

Abstract

The embodiment of the invention discloses a driving method and driving device of a display panel and a display device. The driving method includes the following steps: using 2n rows of sub-pixels in a display panel to form a sub-pixel group, using sub-pixels of odd-numbered rows in the sub-pixel group to form a first sub-pixel group, and using sub-pixels of even-numbered rows to form a second sub-pixel group; for the sub-pixel group formed by the 2n rows of sub-pixels, first driving sub-pixels of the first sub-pixel group to be displayed; and then driving the sub-pixels of the second sub-pixel group to be displayed. The display panel includes a plurality of pixel units arranged in an array; each pixel unit includes at least sub-pixels of three colors, and the sub-pixels of each color include sub-pixels of a first type and sub-pixels of a second type; and the sub-pixels of the first type and the sub-pixels of a second type are arranged at intervals in a row direction and a line direction arranged along the pixel units, and data signals on the sub-pixels of the first type and the sub-pixels of the second type which are provided by a driving module have different levels. Through the technical scheme of the invention, the work efficiency 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
