Description
Technical Field
The invention relates to the technical field of display, in particular to a display panel driving method.
Background
Thin Film Transistors (TFTs) are the main driving elements in current liquid crystal display devices (L acquired crystal display, <tt transfer = L ">t L <t/t >t CD) and Active Matrix driven Organic electroluminescent display devices (Active Matrix Organic L light-Emitting Diode, AMO L ED), and directly relate to the display performance of the flat panel display devices.
Most of the existing liquid crystal displays in the market are backlight liquid crystal displays (lcds), which include a liquid crystal display panel and a backlight module (backlight module). The liquid crystal display panel operates on the principle that liquid crystal molecules are poured between a thin film Transistor Array (TFT Array Substrate) and a color filter (color filter, CF) Substrate, pixel voltage and common voltage are applied to the two substrates, and the rotation direction of the liquid crystal molecules is controlled by an electric field formed between the pixel voltage and the common voltage, so that light of a backlight module is transmitted out to generate a picture.
With the continuous pursuit of display quality, a liquid crystal display with a high refresh rate (e.g., 120HZ) and a high image quality (e.g., 8K) is inevitably a trend of later development, however, a liquid crystal panel with a high refresh rate and a high image quality inevitably causes an increase in load (loading) of a source driver, and when a data signal transmitted to a data line by the source driver is frequently switched between a low gray-scale voltage and a high gray-scale voltage in order to realize the alternation of brightness and darkness of pixels in adjacent rows, the temperature of the source driver is excessively high due to a large voltage difference between before and after the switching, so that the source driver is damaged and cannot normally operate; in addition, a large amount of current is consumed under a heavy-duty picture with alternating bright and dark, and power consumption is increased.
The method is characterized in that the display of a non-overloading picture cannot be changed, and meanwhile, considering the cost of the algorithm, no matter in a 1G1D structure (namely one scanning line corresponds to one row of sub-pixels and one data line corresponds to one column of sub-pixels) or a 1G1D + filp (turnover) structure (namely one scanning line corresponds to one row of sub-pixels and one data line adjacent to two columns of sub-pixels), the amplitude of data compensation is determined by the overloading degree of two adjacent data jumps on the same data line (for example, the data of the same data line is subjected to jump from 0 gray scale voltage to 255 gray scale voltage and then from 255 gray scale voltage to 0 gray scale voltage, and the two times are the most overloading jumps, so the amplitude of data compensation is the maximum), but the overloading picture data compensation method can modify some non-overloading pictures after error detection, but the overloading pictures bring important inspection for the development of L CD panel drive, so the overloading picture compensation method is difficult for developing the overloading picture.

Further, the luminance value compensation algorithm for the reloading frame increases the luminance value of the sub-pixel 20 with the luminance value less than or equal to the preset second luminance value in the reloading frame, so as to reduce the gray scale voltage jump degree of the data line, for example, before the luminance value compensation is not performed on the reloading frame, the gray scale voltage of the data line needs to jump from 255 gray scale voltage to 0 gray scale voltage, and after the luminance value compensation is performed, the gray scale voltage of the data line needs to jump from 255 gray scale voltage to 100 gray scale voltage.
Referring to fig. 2, a second embodiment of a display panel driving method according to the present invention includes the following steps:

however, the x-th frame of display image may be a non-overloaded image, which includes a "tian" shaped display image, that is, luminance values of a row of sub-pixels 20 and a column of sub-pixels 20 in the "tian" shaped display image are both greater than or equal to a preset first luminance value, and luminance values of the remaining sub-pixels 20 are both less than or equal to a preset second luminance value, wherein the first luminance value is greater than the second luminance value, so that there is a "cross" shaped bright line in the "tian" shaped display image, the whole image looks like a "tian" shape, and the "tian" shaped display image is an important inspection image in L CD panel drive development, rather than the overloaded image, and the prior art may perform error compensation on the "tian" shaped display image;
before the brightness value compensation is carried out through the heavy-load picture brightness value compensation algorithm, whether the x-th frame display picture of the display panel 10 is a heavy-load picture or not is judged through the picture detection algorithm, the x-th frame display picture is determined to be the heavy-load picture, the possibility that the x-th frame display picture is a display picture in a shape of a Chinese character 'tian' is eliminated, the brightness value compensation is carried out on the x + 1-th frame display picture, the phenomenon that the display of the non-heavy-load picture is changed due to the fact that the non-heavy-load picture is subjected to error compensation is prevented, and the compensation.
Specifically, the reloading frame is a display frame in which the luminance values of the sub-pixels 20 in the odd-numbered rows are all greater than or equal to a preset first luminance value and the luminance values of the sub-pixels 20 in the even-numbered rows are all less than or equal to a preset second luminance value, or the reloading frame is a display frame in which the luminance values of the sub-pixels 20 in the even-numbered rows are all greater than or equal to a preset first luminance value and the luminance values of the sub-pixels 20 in the odd-numbered rows are all less than or equal to a preset second luminance value, wherein the first luminance value is greater than the second luminance value.
Further, in the step S1', the frame detection algorithm determines whether the display frame x is a reloaded frame according to the luminance values of the sub-pixels 20 in the odd-numbered lines and the even-numbered lines of the display frame x.
Specifically, the heavy-load picture brightness value compensation algorithm performs brightness value compensation on the heavy-load picture, and converts the heavy-load picture into a light-load picture, so that the load of the source driver is reduced.
Further, the luminance value compensation algorithm for the reloading frame increases the luminance value of the sub-pixel 20 with the luminance value less than or equal to the preset second luminance value in the reloading frame, so as to reduce the gray scale voltage jump degree of the data line, for example, before the luminance value compensation is not performed on the reloading frame, the gray scale voltage of the data line needs to jump from 255 gray scale voltage to 0 gray scale voltage, and after the luminance value compensation is performed, the gray scale voltage of the data line needs to jump from 255 gray scale voltage to 100 gray scale voltage.
