Embodiment Construction

[0058] In order to further illustrate the technical means adopted by the present invention and its effects, the following describes in detail in conjunction with preferred embodiments of the present invention and accompanying drawings.

[0059] see figure 1 , the present invention provides a display driving method, comprising the following steps:

[0060] Step S1, such as figure 2 or as image 3 As shown, a display panel is provided, and the display panel is an HG2D display panel.

[0061] Specifically, the display panel includes a plurality of scanning lines 10, a plurality of data lines 20, and a plurality of sub-pixels 30, the plurality of sub-pixels 30 are arranged in an array, and corresponding to each row of sub-pixels 30 is provided a row of sub-pixels electrically connected to the row. The scanning line 10 of the pixel 30 is provided with two data lines 20 corresponding to each column of sub-pixels 30;

[0062] Every two adjacent rows of sub-pixels 30 constitute a...

Abstract

The invention provides a display driving method and a display panel. The display driving method comprises the following steps: step S1, providing a display panel; s2, obtaining the original gray level of each sub-pixel in the current frame of image; s3, judging whether the current frame of picture is a heavy-load picture or not according to the original gray level of each sub-pixel; and if yes, converting the original gray level of each sub-pixel in the current frame of image according to a preset heavy-load conversion algorithm to obtain a corrected gray level of each sub-pixel, and driving each sub-pixel to display the image by using the corrected gray level, otherwise, directly driving each sub-pixel to display the image by using the original gray level. By converting the original gray scale of each sub-pixel under the heavy-load picture into the correction gray scale, the driving load can be reduced, the overhigh temperature of the driving chip caused by the heavy-load picture is avoided, and the display quality is ensured.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display driving method and a display device. Background technique [0002] With the development of display technology, liquid crystal displays (Liquid Crystal Display, LCD) and other flat display devices are widely used in mobile phones, televisions, personal Various consumer electronic products such as digital assistants, digital cameras, notebook computers, and desktop computers have become the mainstream of display devices. [0003] The liquid crystal display panel includes a plurality of sub-pixels arranged in an array, each sub-pixel is electrically connected to a thin film transistor (TFT), the gate (Gate) of the TFT is connected to the gate scanning line in the horizontal direction, and the drain (Drain ) is connected to the data line in the vertical direction, and the source (Source) is connected to the pixel electrode. Applying sufficient voltage on the gate...
