Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of display, in particular to a display brightness adjustment method and device, electronic equipment and storage medium. BACKGROUND

[0002] With the gradual diversification of people's life and work scenes, the application scenarios of large-size LCD (Liquid Crystal Display) are increasingly widespread. For large-size LCD, the first thing to consider is to solve the problem of viewing angle defects, so the compensation algorithm for large-size LCD viewing angle defects has emerged.

[0003] The principle of the known VAC (View Angle Compensation) algorithm is to replace the original gray scale value with two gray scales that are relatively high (H) and relatively low (L), to ensure that the viewing angle brightness and the gray scale relationship remain unchanged, and to correct the side viewing brightness and the gray scale relationship. The Vft (feedthrough voltage) influence caused by the coupling capacitance will make the pixel potential lower than the input data potential, because the positive / negative voltage will be pulled down by Vft, and the positive voltage is usually reduced and the negative voltage is increased. Different pixels have different Vft, although the input voltage is consistent, the final pixel voltage (Vp) is also inconsistent. Since the pixel brightness is determined by the common electrode and Vp, after applying the VAC algorithm, the positive and negative polarity brightness of different pixels in the minimum cycle will have differences and show a regular distribution. When the human eye shakes at a certain frequency, the shaking lines will be observed. SUMMARY

[0057] As Figure 1 The schematic diagram of a liquid crystal display panel of the prior Tri-gate architecture is shown, which includes a plurality of sub-pixels arranged in an array, the sub-pixels including red sub-pixels R, green sub-pixels G, and blue sub-pixels B, and in each column of sub-pixels, the red sub-pixels R, the green sub-pixels G, and the blue sub-pixels B are alternately and repeatedly arranged in sequence. By adopting the Tri-gate architecture, the number of scan lines can be increased by three times, and the number of data lines can be reduced to 1 / 3 of the original, thereby reducing the number of data lines of the source driver, and reducing the cost of the source driver.

[0058] Figure 2 And Figure 3Two VAC adjustment schemes of the current Tri-gate architecture liquid crystal display panel, wherein the display polarity includes positive polarity and negative polarity, the pixels in the same column maintain the same display polarity, the gray scale values of adjacent rows are different, and the arrangement modes of the polarities and the gray scale values of the pixels in different columns are different. Figure 2 HHLL pixel mapping is matched with +-+ polarity, Figure 3 HL pixel mapping is matched with ++- polarity, as shown in Figure 2 and Figure 3 As shown in the figure, the luminance of H+ is different from that of H-, that is, the gray scale values are the same, but the display polarities are different, so that the overall situation of one column of pixels being dark and one column of pixels being bright occurs, and when the human eye shakes at a certain frequency, the wobble lines are observed. In addition, HHLL matched with ++- or HL matched with +-+ will have other side effects such as crosstalk and flicker. It should be noted that the embodiments of the present application are also applicable to other pixel architecture liquid crystal display panels, such as Sigal-gate, Dual-gate, etc.

[0059] Please refer to Figure 4 The display luminance adjustment method provided in the embodiments of the present application includes steps S101-S104, and the details are as follows.

[0060] S101, obtaining the original gray scale value of a display panel to-be-displayed picture and the display polarity of each pixel in the display panel.

[0061] Specifically, the original gray scale value of a display panel to-be-displayed picture and the display polarity of each pixel in the display panel are obtained, the display polarity includes positive polarity and negative polarity, the pixels in the same column maintain the same display polarity, and the display polarities of adjacent column pixels can be the same or different. Figure 5 and Figure 8 For a certain to-be-displayed picture, the original gray scale values are all L96, and the difference is that Figure 5 in the middle, the display polarities of the pixels along the pixel row direction are +-+, that is, positive and negative are alternated, Figure 8 in the middle, the display polarities of the pixels along the pixel row direction are ++-.

[0062] S102, determining the first gray scale value and the second gray scale value after the original gray scale value is compensated for viewing angle based on a preset gray scale mapping table, and the original gray scale value is set between the first gray scale value and the second gray scale value.

[0063] Specifically, the first gray scale value and the second gray scale value after the original gray scale value is compensated for viewing angle are determined based on a preset gray scale mapping table, and the original gray scale value is set between the first gray scale value and the second gray scale value. The preset gray scale mapping table is determined based on the principle of constant luminance after compensation for viewing angle, and the gray scale values after compensation for each gray scale value are set in the gray scale mapping table.

[0064] In one embodiment, the step further comprises: S201, obtaining pixel brightness corresponding to each gray scale value of the display panel, and pixel brightness sum of two pixels of the same gray scale value; S202, determining compensation gray scale combination of the same gray scale value according to the pixel brightness and the pixel brightness sum; and S203, determining the gray scale mapping table according to the same gray scale value and the corresponding compensation gray scale combination.

[0065] Specifically, the pixel brightness corresponding to each gray scale value of the display panel is obtained, and the pixel brightness sum of two pixels of the same gray scale value is obtained, and the compensation gray scale combination of the same gray scale value is determined according to the pixel brightness and the pixel brightness sum. For example, the pixel brightness of gray scale L96 is obtained, and the pixel brightness sum of two pixels displaying gray scale L96 is obtained, the brightness of other arbitrary two compensation gray scales which are not gray scale L96 is integrated, and compared with the pixel brightness sum of two pixels displaying gray scale L96, if the same, the compensation gray scale combination is determined as the compensation gray scale of gray scale L96, if there are multiple compensation gray scale combinations, one of them is selected according to the requirement, for example, the compensation gray scale combination with the smallest difference from the original gray scale value is selected, and the compensation gray scales of each gray scale value are determined in turn to obtain the gray scale mapping table.

[0066] S103, determining arrangement information of the first gray scale value and the second gray scale value based on the display polarity of each pixel.

[0067] Specifically, the above-mentioned compensation gray scale value (the first gray scale value and the second gray scale value) of the original gray scale value is only determined based on the gray scale mapping table, but the position of the first gray scale value and the second gray scale value will affect the appearance of the wobble lines, and the distribution of the display polarity of each pixel is different, and the arrangement information of the corresponding first gray scale value and the second gray scale value is different.

[0068] In one embodiment, since the wobbling is caused by the difference in brightness of the same gray scale value under positive and negative polarity, the pixels in the same column remain the same display polarity, the display polarity of the pixels in different columns can be different, and in order to ensure the uniformity of the display brightness, in any viewing angle compensation scheme, the number of pixels corresponding to the first gray scale value and the second gray scale value is the same, the number of pixels corresponding to the first gray scale value under positive polarity and the first gray scale value under negative polarity is the same, the number of pixels corresponding to the second gray scale value under positive polarity and the second gray scale value under negative polarity is the same, so the embodiment actually adjusts the positions of the first gray scale value under positive polarity, the first gray scale value under negative polarity, the second gray scale value under positive polarity and the second gray scale value under negative polarity to balance the brightness, breaks the rule of one bright column and one dark column, and actually does not increase or decrease the number of pixels corresponding to the first gray scale value under positive polarity, the first gray scale value under negative polarity, the second gray scale value under positive polarity and the second gray scale value under negative polarity.

[0069] In the prior art VAC adjustment scheme, the gray scale values of the adjacent pixels in the same column are different, Figure 6 the current VAC adjustment scheme is adjusted to Figure 5 obtain a scheme, Figure 9 the current VAC adjustment scheme is adjusted to Figure 8 obtain a scheme, in order to avoid new brightness unevenness caused by the position adjustment of the first gray scale value under positive polarity, the first gray scale value under negative polarity, the second gray scale value under positive polarity and the second gray scale value under negative polarity, in the embodiment, the display polarities of any two target pixels in the same column are different, and there is one pixel between the two target pixels. Figure 7 the current VAC adjustment scheme is adjusted to Figure 5 obtain a scheme, Figure 10 the current VAC adjustment scheme is adjusted to Figure 8 obtain a scheme, that is, the display polarities of the pixels in the same column are no longer arranged alternately in positive and negative polarities, but are arranged alternately in the same display polarity two by two.

[0070] In one embodiment, the display polarity includes positive polarity and negative polarity, the arrangement information includes row arrangement information of the first gray scale value and the second gray scale value, and the row arrangement information is that the gray scale values displayed by the pixels under positive polarity and negative polarity in the same pixel row are different, that is, in the same row of pixels, the same gray scale value corresponds to the same display polarity as much as possible, so as to avoid the difference in brightness caused by the same gray scale value corresponding to different display polarities.

[0071] In one embodiment, step S103, determining the arrangement information of the first gray scale value and the second gray scale value based on the display polarity of each pixel, comprises: S301, if the display polarity of each pixel is that the positive polarity pixels and the negative polarity pixels are arranged alternately in the pixel row, the row arrangement information is that the first gray scale value and the second gray scale value are arranged alternately in the pixel row; S302, if the display polarity of each pixel is that the display polarity of any two target pixels is different in the pixel row, the gray scale values displayed by the two target pixels are different, and one pixel is arranged between the two target pixels.

[0072] Specifically, based on the current display panel, the display polarity of the pixels along the pixel row direction comprises two types of ++-- and +-+-. As shown in Figure 7 If the display polarity of each pixel is that the positive polarity pixels and the negative polarity pixels are arranged alternately in the pixel row, i.e. +-+ arrangement, the corresponding row arrangement information is that the first gray scale value and the second gray scale value are arranged alternately in the pixel row. As shown in Figure 10 If the display polarity of each pixel is that the display polarity of any two target pixels is different in the pixel row, i.e. ++-- arrangement, the gray scale values displayed by the two target pixels are different, and one pixel is arranged between the two target pixels.

[0073] S104, determining the display parameters of each pixel according to the display polarity, the first gray scale value, the second gray scale value and the arrangement information.

[0074] Specifically, the first gray scale value and the second gray scale value are arranged according to the determined arrangement information, and the display polarity of each first gray scale value and second gray scale value is set according to the display polarity, so as to determine the display parameters of each pixel in the display panel.

[0075] In one embodiment, this step comprises: S401, if the display polarity of each pixel is that the positive polarity pixels and the negative polarity pixels are arranged alternately in the pixel row, the display parameters of a first pixel unit are determined according to the display polarity, the first gray scale value L1, the second gray scale value L2 and the arrangement information, the first pixel unit comprises 2*4 pixels, and the display parameters of the first pixel unit are S402, the display parameters of the first pixel unit are arranged along the pixel row and the pixel column to obtain the display parameters of each pixel.

[0076] Specifically, as shown in Figure 7As shown, if the display polarity of each pixel is an alternating arrangement of positive and negative pixels in a pixel row (+-+- arrangement), then the final determined adjustment scheme retains the same display polarity for each pixel. Pixels in the same column still have the same display polarity, and positive and negative pixels in the pixel row are arranged alternately (+-+- arrangement). Based on the arrangement information, the first grayscale value L1 and the second grayscale value L2 in the pixel row are determined to be alternately arranged. The grayscale values ​​of two target pixels in a pixel column are different, thus determining the smallest repeating unit of the grayscale arrangement of the display panel. The first pixel unit contains 2*4 pixels, and the display parameters of the first pixel unit are... Then, the display parameters of the first pixel unit are arrayed along the pixel rows and columns to obtain the display parameters of each pixel. In addition, considering that different pixels have different color resist colors, including red, green and blue pixels, the smallest repeating unit contains 2*12 pixels based on the pixel arrangement rules.

[0077] In one embodiment, step S104, determining the display parameters of each pixel based on the display polarity, the first grayscale value, the second grayscale value, and the arrangement information, includes: S501, if the display polarity of each pixel is such that the display polarities of any two target pixels in a pixel row are different, then determining the display parameters of the second pixel unit based on the display polarity, the first grayscale value L1, the second grayscale value L2, and the arrangement information, wherein the second pixel unit contains 4*4 pixels, and the display parameters of the second pixel unit are... S502, the display parameters of the second pixel unit are arrayed along the pixel row and pixel column to obtain the display parameters of each pixel.

[0078] Specifically, such as Figure 10 As shown, if the display polarity of each pixel is such that the display polarities of any two target pixels in a pixel row are different (i.e., arranged in ++--), then the display polarity of each pixel in the final determined adjustment scheme remains unchanged. Pixels in the same column still have the same display polarity, and pixels with positive and negative polarities in a pixel row are arranged in ++--. Based on the arrangement information, the first grayscale value L1 and the second grayscale value L2 in the pixel row are determined to be arranged in ++--, the same as the display polarity. The grayscale values ​​of two target pixels in a pixel column are different, thus determining the smallest repeating unit of the grayscale arrangement of the display panel. The second pixel unit contains 4*4 pixels, and the display parameters of the second pixel unit are... Then, the display parameters of the second pixel unit are arrayed along the pixel rows and columns to obtain the display parameters of each pixel. In addition, considering that different pixels have different color resist colors, including red, green and blue pixels, the smallest repeating unit contains 4*12 pixels based on the pixel arrangement rules.

[0079] The embodiment does not increase or decrease the number of pixels corresponding to the positive first gray scale value, the negative first gray scale value, the positive second gray scale value and the negative second gray scale value relative to the existing VAC adjustment scheme, but adjusts the positions of the positive first gray scale value, the negative first gray scale value, the positive second gray scale value and the negative second gray scale value to balance the brightness, break the rule of one bright column and one dark column, and eliminate the wobble lines.
