Embodiment Construction

[0041] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0042] The inventors of the present invention have found that the display unevenness such as stripes is likely to occur when the display panel is displaying due to the negligible influence of the parasitic capacitance when the data voltage is supplied to the display panel. Combine below figure 1 The specific embodiment shown in will explain in detail the reasons for the display unevenness.

[0043] Such as figure 1 As shown in , the display panel includes a plurality of pixel units arranged in multiple rows and columns, and each pixel unit includes three sub-pixel units ( figure 1 The sub-pixel unit 100, the sub-pixel unit 200 and the sub-pixel unit 300 are s...

Abstract

The present invention provides a driving method of a display panel. The display panel includes a plurality of sub data line groups, and each of the sub data line groups includes a plurality of sub data lines. The driving method includes providing a data signal for each of the sub data lines of each sub data line group, wherein among the sub data lines in the sub data line groups, the sub data linefirst receiving the data signal has the shortest data signal duration. The present invention also provides a driving circuit and a display device including the driving circuit. The display panel canbe made to emit light uniformly by the driving method.

Description

technical field [0001] The present invention relates to the field of display technology, in particular, to a driving method of a display panel, a driving circuit for executing the driving method, and a display device including the driving circuit. Background technique [0002] The display device includes a plurality of pixel units arranged in multiple rows and multiple columns. Each pixel unit includes a plurality of sub-pixel units. In order to simplify the structure, a multiplexer is usually used to provide data signals to sub-pixel units in different columns of the same column of pixel units. However, when displaying, the display screen is uneven and streaks are prone to appear. Therefore, how to prevent stripes from appearing during display has become an urgent technical problem in this field. Contents of the invention [0003] The object of the present invention is to provide a driving method of a display panel, a driving circuit for executing the driving method, a...
