- a pixel is usually displayed together with the surrounding pixels.
- the target pixel is a pixel in a sunset image, but when displaying a sunset picture, the target pixel and nearby pixels jointly display a sunset area, and the brightness is low.
- the process of determining the regional compensation parameters can be started when the brightness difference between the target pixel and the overall picture exceeds a certain brightness difference threshold. After the process of determining the regional compensation parameters is started, the size of the specific regional compensation parameters can be determined based on the current color information of the target pixel.
- the visual effect will not be particularly obvious, so a larger area compensation parameter can be appropriately selected, so that when charging compensation is performed, even if the pixels of normal brightness are included in the display area, after the brightness is enhanced, there will be no large deviation in the visual effect.
- the brightness compensation of the target pixel needs to be performed according to the brightness difference.
- the brightness compensation at this time is to perform brightness compensation on the target display area. That is, the overall brightness compensation is performed on the target display area.
- the brightness of the target pixel is A
- the brightness of the overall picture is B.
- the brightness of the target display area can be displayed with brightness B. That is, according to the voltage corresponding to brightness B, the voltage compensation of the target display area can be performed.
- the voltage compensation method provided by the present application determines the pixel information of the target pixel point, and then determines a region compensation parameter according to the pixel information, thereby obtaining a target display region in a display panel. After that, voltage compensation is performed on the target display region. There is no need to perform voltage compensation on each pixel point individually, which reduces the calculation burden.
- the pixel information includes a first grayscale binding value of the target pixel point, and the regional compensation parameter corresponding to the target pixel point is determined according to the pixel information, including:
- the above embodiment provides a scheme for determining regional compensation parameters using pixel information including color information and brightness information.
- the present application embodiment also provides a scheme for determining regional compensation parameters using fewer parameters.
- binding grayscale values is the grayscale value set corresponding to the pixel row or pixel column. It can be understood that in a display panel, the pixel row or pixel column where a pixel point is located corresponds to a bound grayscale value, so that when displaying the picture, the grayscale value is determined according to the bound grayscale value.
- the preset matching rule can be to detect whether there is an adjacent, previous pixel column for the target pixel. If so, the target pixel has a matching target adjacent pixel. At this time, the grayscale value bound to the target adjacent pixel is obtained, and the bound grayscale value is the grayscale value bound to the pixel column where the target adjacent pixel is located.
- the first grayscale binding value of the target pixel can be the bound grayscale value of the pixel row or pixel column where the target pixel row is located. Afterwards, the first bound grayscale value is subtracted from the adjacent bound grayscale value.
- two difference thresholds can be pre-set, difference threshold a and difference threshold b.
- the area compensation parameter 1 may be a parameter with a range size of 3 ⁇ 5
- the area compensation parameter 2 may be a parameter with a range size of 3 ⁇ 17
- the area compensation parameter 3 may be a parameter with a range size of 5 ⁇ 33.
- determining whether there is a matching target adjacent pixel point for a target pixel point according to a preset matching rule includes:
- the embodiment of the present application also provides a matching rule for determining whether there is an adjacent, previous pixel row for the target pixel. Specifically, it can be detected whether there is an adjacent, previous pixel row for the target pixel. If so, the target pixel has a matching target adjacent pixel. At this time, the bound grayscale value of the target adjacent pixel is obtained. At this time, the bound grayscale value is the grayscale value bound to the pixel row where the target adjacent pixel is located. Afterwards, the first bound grayscale value is subtracted from the adjacent bound grayscale value. Similar to the above embodiment, two difference thresholds can still be pre-set in this embodiment, the difference threshold a and the difference threshold b.
- each pixel row corresponds to a pixel row identifier, and therefore, only the first pixel row does not have an adjacent previous pixel row. Therefore, when the acquired pixel row identifier represents the first pixel row, there is no adjacent previous pixel row, and other pixel row identifiers all have adjacent previous pixel rows.
- the method further includes:
- a preset reference binding grayscale value is obtained; and a region compensation parameter corresponding to the target pixel is determined according to a grayscale difference between the first binding grayscale value and the reference binding grayscale value.
- the center point of the region is determined; according to the center point of the region and the regional compensation parameter, the target display region is determined; and the brightness compensation is performed on the target pixel point in the target display region.
- the regional compensation parameter can be a regional compensation parameter that characterizes a rectangular area.
- the regional compensation parameters listed in the above embodiments can be 3 ⁇ 5, 3 ⁇ 17, and 5 ⁇ 33, etc.
- the coordinates of the target pixel point can still be used as the center point.
- the coordinates of the target pixel point can be (1010, 877).
- the corresponding enhancement weight can be set for each pixel in advance.
- the corresponding weight can be adjusted in advance according to the specifications of the display panel. For example: in a 4K display panel, the resolution is 3860 ⁇ 2160, so a corresponding weight can be set for each pixel at each coordinate.
- the coordinates corresponding to the target pixel are (1806, 1100)
- the pre-set weight corresponding to the coordinates are (1806, 1100)
- multiply the brightness value corresponding to the target pixel by the weight For example: assuming that the brightness of the target pixel is J, multiply the brightness J by the weight K corresponding to the coordinates (1806, 1100) to obtain the target brightness value.
- the target display area is then brightness compensated according to the charging voltage matching the target brightness value.
- the method of obtaining the target display area is the same as that in the above embodiment, and will not be described in detail here.
- the grayscale value of the target pixel is compensated according to a preset weight, including:
- the initial brightness value of the target pixel value can be multiplied by the weight to obtain the target brightness value.
- the brightness corresponding to the target pixel value is higher than the brightness of the entire picture.
- the target pixel can still be determined by determining the grayscale value bound between the pixel row where the target pixel is located and an adjacent pixel row before the pixel row. For example: when the first bound grayscale value of the pixel row where the target pixel is located is less than the second bound grayscale value of the adjacent previous pixel row, it proves that the brightness of the target pixel needs to be enhanced; if the first bound grayscale value of the pixel row where the target pixel is located is greater than the second bound grayscale value of the adjacent previous pixel row, it proves that the brightness of the target pixel needs to be reduced.
- the compensation voltage is obtained according to the target brightness value according to the above embodiment, and then the target display area is charged and compensated according to the compensation voltage, which will not be described in detail here.
- the voltage compensation scheme provided by the embodiment of the present application can be specifically summarized as follows: obtain a target pixel point, which can be any pixel point in the display panel. Determine the first binding grayscale value of the pixel row (column) where the target pixel point is located, and determine the binding grayscale value of the previous pixel row (column) adjacent to the pixel row where the target pixel point is located. If there is no adjacent pixel row, obtain a preset reference binding grayscale value, and use the binding grayscale value or reference binding grayscale value of the adjacent previous pixel row (column) as the second binding grayscale value. Then, calculate the size of the first binding grayscale value and the second binding grayscale value.
- a regional compensation parameter can also be determined based on the difference between the first bound grayscale value and the second bound grayscale value to determine a target display area, so that the brightness of each pixel in the target display area is increased or decreased according to the compensation voltage.
- Table 1 is a grayscale value table for grayscale value search of target pixel points
- Table 2 is a weight lookup table for weight search of target pixel points.
- the grayscale difference value is negatively correlated with the number of pixels in the display area corresponding to the area compensation parameter; or, the grayscale difference value is positively correlated with the number of areas in the display area corresponding to the area compensation parameter.
- the compensation area may also include a large number of pixels with large grayscale value differences.
- the grayscale value difference should be compensated to make the grayscale value difference smaller.
- unified brightness compensation will be performed, and the effect will be better. Therefore, the greater the grayscale value difference is, the smaller the regional compensation parameter is, which can avoid including a large number of pixels with large grayscale value differences in the compensation area, thereby alleviating the problem of poor brightness compensation.
- Table 3 below.
- Table 3 and Table 2 both represent display panels of the same specification. According to Table 3, assuming that there is a pixel point A (1, 1), at this time, according to any of the above embodiments, it is assumed that the regional compensation parameter corresponding to the grayscale difference A of pixel point A is 3 ⁇ 5. And, based on the position of (1, 1) in Table 2, the weight value of pixel point A can be obtained as 150%. At this time, an area with a size range of 3 ⁇ 5 can be determined based on the position of pixel point A, that is, the coordinate (1, 1). For example, the area with a value of 150% in all cells in Table 3 is the display area A of pixel point A, and the size of the display area A is 3 in length and 5 in width. At this time, for the voltage corresponding to the weight of 150%, the brightness compensation of the display area A can be performed.
- the coordinates of the pixel point B are (6, 1).
- the weight corresponding to the pixel point B is 130%, and based on any of the above embodiments, the grayscale difference B of the pixel point B is obtained.
- the grayscale difference B can correspond to a smaller regional compensation parameter, such as 2 ⁇ 3.
- the brightness compensation of the display area B can be performed by the voltage corresponding to the weight of 130%. It can be seen that the larger the grayscale difference value, the smaller the regional compensation parameter, and the fewer the number of pixels included in the display area corresponding to the regional compensation parameter.
- Table 3 can characterize a display panel after the display panel completes compensation.
- the regional compensation parameter can represent a one-dimensional parameter, such as a parameter that is positively correlated with the number of regional areas.
- a positive correlation function between the number of regional areas and the grayscale difference.
- the regional compensation parameter corresponding to the grayscale difference A of pixel point A is 2, and based on the position of (1, 1) in Table 2, the weight value of pixel point A can be obtained as 150%.
- the entire display panel can be divided into regions with a regional compensation parameter of 2 according to the position of pixel point A, that is, the coordinate (1, 1).
- the area with a 150% in all cells in Table 4 is the display area A of pixel point A, and the size of the display area A is 2 in length.
- the display area A can be brightness compensated.
- Table 5 and Table 2 also represent display panels of the same specifications.
- the grayscale difference A of pixel point A is obtained, and the grayscale difference A is input into the positive correlation function, assuming that the obtained area compensation parameter is 5.
- the weight value of pixel point A can be obtained as 150%.
- a 5-column compensation area can be determined based on the position of pixel point A, that is, the coordinate (1, 1). Such as the area of 150% in all cells in Table 5.
- the brightness compensation of the display area A can be performed.
- LOD is the brightness value of the target pixel, which is 4 in this embodiment
- Gain is the weight corresponding to the position of the target pixel, which is 100% in this embodiment.
- the target brightness value is still 4.
- data current line is the first binding grayscale value
- data pre line is the second binding grayscale value
- a and b are the difference thresholds between the previous row of data and the current data, which can be set according to the charging condition of the visual panel.
- Gain lut1, gain lut2, gain lut3 can also be set according to the specific situation, and are not limited here. Therefore, according to formula 2, the target display area corresponding to the target pixel point can be obtained. It should be noted that in the embodiment of the present application, after the target display area is voltage compensated, the pixel points in the target display area will no longer be used as another target pixel point to be compensated to determine whether voltage compensation is required.
- Table 6 represents the weight table used when the bound gray value of the previous row of the target pixel is greater than the bound gray value of the current row. Assuming that the bound gray value of the previous row of pixel A is greater than the bound gray value of the current row, find the coordinates of pixel A in Table 6. Assuming that the coordinates of pixel A are (1, 1), the weight value of pixel A is 150%. At this time, 150% is substituted into the above formula 1 to obtain the LOD final of pixel A.
- Table 7 can represent the weight table used when the bound gray value of the previous row of the target pixel is less than the bound gray value of the current row. Assuming that the bound gray value of the previous row of pixel A is greater than the bound gray value of the current row, find the coordinates of pixel A in Table 6. Assuming that the coordinates of pixel A are (1, 1), the weight value of pixel A is 150%. At this time, 90% is substituted into the above formula 1 to obtain the LOD final of pixel A.
