Embodiment Construction

[0022] As shown in FIG. 1, which is a schematic diagram of a display device according to an embodiment of the present application. The display device 100 is vertically oriented

[0036]

[0038]

[0042] Specifically, when the data voltage of the sub-pixel from the previous frame to the current frame jumps from a positive polarity high grayscale (+H) to a negative

[0044] The display device of this embodiment compensates for the grayscale data of the sub-pixels that meet the preset compensation conditions to improve the

[0051] S103: The sub-pixel is displayed in the current frame according to the data voltage corresponding to the corrected grayscale data.

Abstract

The present application provides a display device and a display method thereof. The method includes: acquiring a change of gray-scale data of a sub-pixel between a current frame and a previous frame and the polarity of a data voltage of the sub-pixel between the current frame and the previous frame. When the gray-scale data of the sub-pixel changes between the current frame and the previous frame and the polarity of the data voltage of the sub-pixel between the current frame and the previous frame meets the preset compensation condition, then according to the sub-pixel The difference between the gray-scale data of the pixel in the current frame and the gray-scale data of the previous frame, the change of the polarity of the data voltage of the sub-pixel between the current frame and the previous frame, and the corresponding preset compensation data set determine the gray level. level compensation data, the preset compensation data set includes the preset difference value and the preset gray-level compensation data corresponding to the preset difference; according to the gray-level data of the sub-pixel in the current frame and the gray-level compensation data, determine the sub-pixel in the current frame. Correct the gray-scale data; the sub-pixels are displayed in the current frame according to the data voltage corresponding to the corrected gray-scale data.

Description

Display device and display method thereof technical field [0001] The present application relates to the field of display technology, and in particular, to a display device and a display method thereof. Background technique [0002] At present, for a data line connected to a column of sub-pixels and a row of sub-pixels to be connected to a scan line In the liquid crystal display device, when the grayscale data applied to each sub-pixel performs high and low grayscale switching between two adjacent frames, applying The polarities of the data voltages to the adjacent two columns of sub-pixels are opposite, and the polarity of the data voltages applied to each sub-pixel is When it is reversed once, that is, when driven by the time-domain Viewing Angle Control (VAC) algorithm, the liquid crystal display is When the setting is displayed, a shaking head pattern will appear. Therefore, it is necessary to propose a kind of technical scheme to solve the shaking head that exist...
