[0003] In the field of display technology, due to the influence of factors such as materials and manufacturing processes, the display screen may exhibit uneven brightness distribution, which is referred to as Mura phenomenon.

[0078] In order to make the purpose, technical solutions and advantages of the present application more clear, the following will further describe the embodiments of the present application in combination with the drawings.

[0079] It should be noted that the terms "first", "second", and the like in this application are used to distinguish similar objects, and do not necessarily indicate a specific order or a chronological sequence. It should be understood that the terms thus used can be interchanged under appropriate circumstances, so that the embodiments of the application described herein can be implemented in an order other than that illustrated or described herein. The implementation described in the following exemplary embodiments does not represent all implementations consistent with the present application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the present application as detailed in the appended claims.

[0080] In the field of display technology, due to the influence of factors such as materials, manufacturing processes, etc., the display screen appears uneven brightness distribution phenomenon, which is called Mura (mura) phenomenon. In the related art, the Mura phenomenon can be eliminated by Demura technology. Demura technology is based on Demura compensation algorithm, calculates the compensation data of each pixel point according to the brightness data of each pixel point on the display screen, and performs brightness compensation through the compensation data, so as to make the brightness of the display screen uniformly distributed.

[0081] However, since the darker or brighter the pixel point is, the greater the compensation required is, the above-mentioned technology is prone to over-compensation phenomenon, which causes the display screen to appear bright or dark areas, resulting in poor display effect and affecting the user's viewing experience. In view of this, the embodiments of the present application propose a brightness compensation method, which can avoid the over-compensation phenomenon, make the brightness of the display screen consistent, improve the display effect, and thus improve the user's viewing experience.

[0082] As shown in FIG. 1, FIG. 1 is a computer system schematic diagram of a brightness compensation method provided by an embodiment of the present application, which includes a terminal device 101 and a server 102. Wherein, the terminal device 101 is installed and runs with a client, and the server 102 is used to provide background service for the client. The brightness compensation method provided by the embodiments of the present application can be executed by the terminal device 101.

[0083] Optionally, the terminal device 101 can be any kind of electronic device product that can interact with the user through one or more ways such as keyboard, touchpad, remote controller, voice interaction or handwriting device, etc. For example, the terminal device 101 can be a smart phone, a tablet computer, a notebook computer, a desktop computer, a smart speaker, a smart watch, a PC (Personal Computer), a mobile phone, a PDA (Personal Digital Assistant), a wearable device, a PPC (Pocket PC), a smart car machine, a smart television, etc.

[0084] The terminal device 101 can be used to represent one of a plurality of terminal devices, and the embodiment is only used to illustrate the terminal device 101. Those skilled in the art can know that the number of the terminal device 101 can be more or less. For example, the terminal device 101 can be only one, or the terminal device 101 can be dozens or hundreds, or more, and the number and type of the terminal device 101 are not limited in the embodiment.

[0085] Those skilled in the art can understand that the terminal device 101 is only used for illustration, and other existing or future terminal devices, such as those applicable to the present application, should also be included in the protection scope of the present application, and are hereby incorporated by reference.

[0086] As shown in FIG. 2, FIG. 2 is a flowchart of a brightness compensation method provided by the embodiment, which can be applied to the computer system. In the following, the terminal device 101 performing the method of the embodiment can also be referred to as an electronic device. The method of the embodiment includes the following steps.

[0087] In step 201, original brightness data of a plurality of pixel points on the display screen is obtained.

[0088] The electronic device includes a display screen to display text, images and other information through the display screen. In the example, the display screen can be used to display a specified image, and the brightness of each pixel point on the specified image is the same. In theory, the brightness of each pixel point on the display screen is the same, but due to the influence of manufacturing process, material and other factors, the brightness distribution on the display screen is uneven, resulting in bright spots and dark blocks on the display screen. To this end, an industrial camera can be used to capture the display screen to obtain a captured image, and the captured image is input to the electronic device, so that the electronic device can obtain the original brightness data of each pixel point from the captured image. It can be understood that since the captured image is obtained by capturing the display screen displaying the specified image, the brightness data of any pixel point in the display screen region on the captured image is the original brightness data of the corresponding pixel point on the display screen.

[0089] In step 202, a first region to be adjusted on the display screen is determined according to the original brightness data of the plurality of pixel points.

[0090] It has been mentioned above that, due to the influence of manufacturing process, material and other factors, even if the display screen displays a specified image, the brightness on the display screen is still unevenly distributed, as shown in FIG. 3. The area indicated by reference numeral 301 has uneven brightness distribution, and the area outside reference numeral 301 also has uneven brightness distribution. For this reason, in the related art, compensation data of each pixel point on the display screen can be calculated according to the brightness data of each pixel point on the display screen based on the Demura compensation algorithm, and the brightness compensation is performed through the compensation data. However, this technology is prone to over-compensation, which causes the display screen to have bright areas or dark areas. As shown in FIG. 4, the area indicated by reference numeral 401 has a dark area, and the area indicated by reference numeral 402 has a bright area. After the brightness compensation, the display screen has bright spots and dark blocks, which leads to poor display effect and reduces the viewing experience of the user.

[0091] Based on the above reasons, the embodiment of the present application first determines a first area to be adjusted on the display screen according to the original brightness data of a plurality of pixel points, so as to adjust the original brightness data of the first area. Subsequently, the compensation data is determined based on the Demura compensation algorithm through the adjusted first area, and after the brightness compensation through the compensation data, the bright spots or dark blocks can be eliminated to improve the display effect.

[0092] The determination method of the first area is not limited here. For example, the electronic device can obtain the display screen image after the brightness compensation by using the related technology, determine the bright spot area or dark block area based on the display screen image, and the bright spot area or dark block area is the first area to be adjusted. The first area is at least one, for example, the dark block area indicated by reference numeral 401 is the first area, and the bright spot area indicated by reference numeral 402 is also the first area.

[0093] In a possible implementation, step 202 includes steps 2021 to 2023 (not shown in the figure).

[0094] In step 2021, reference brightness data is obtained, which is used to indicate the display brightness of the display screen.

[0095] Due to the influence of manufacturing process, material and other factors, the display brightness of different display screens is different, so that different display screens correspond to different reference brightness data. The electronic device can obtain the reference brightness data, and the obtaining method is not limited here. For example, the display screens of the same batch correspond to the same display brightness, and the reference brightness data of each display screen of the batch can be obtained through experimental verification, and the reference brightness data is input into the electronic device. Alternatively, the electronic device can calculate the reference brightness data according to the photographed image of the display screen.

[0096] Optionally, step 2021 comprises: determining a reference region on the display screen which is not located at the edge; and calculating the average value of the original brightness data of each pixel point on the reference region to obtain the reference brightness data.

[0097] In the embodiments of the present application, the electronic device can obtain at least one of the position data or the size data of the reference region to locate the size and position of the reference region on the display screen through the data. The shape of the reference region is not limited herein, for example, the reference region can be any shape such as a rectangle, a circle, an ellipse, a triangle, etc. Taking the shape of the reference region as a rectangle as an example, the electronic device can obtain the coordinate data of the diagonal vertex of the rectangle, or the electronic device can obtain the length, the width and the coordinate data of one vertex of the rectangle, etc. to locate the size and position of the reference region on the display screen. After the electronic device locates the reference region on the display screen, the original coordinate data of each pixel point on the reference region can be obtained, the average value of the original brightness data is calculated to obtain the reference brightness data.

[0098] Generally, after the brightness compensation is performed by using the related technology, the bright spot region or the dark block region is located at the edge of the display screen, and the brightness distribution of the non-edge region on the display screen is relatively uniform, such as the regions shown by the reference numerals 401 and 402. Based on this, the reference brightness data can be determined according to the reference region on the display screen which is not located at the edge, for example, according to the reference region located at the center of the display screen to improve the accuracy of the reference brightness data. Subsequently, the first region to be adjusted can be accurately determined based on the reference brightness data, so that the compensation data is determined based on the adjusted first region, and the first region is compensated by using the compensation data, which can prevent the first region from being over-compensated, thereby avoiding the bright spot or the dark block on the display screen.

[0099] Step 2022: calculating the first ratio between the original brightness data of the plurality of pixel points and the reference brightness data. That is, for any pixel point, the original brightness data of the pixel point is divided by the reference brightness data to obtain the first ratio of the pixel point. The first ratio can reflect the difference between the original brightness data of the pixel point and the reference brightness data, and the farther the first ratio is from 1, the greater the difference is.

[0100] Step 2023: determining the first region according to the first ratio of the plurality of pixel points.

[0101] Generally, when the brightness compensation is performed by using the related technology, the darker or brighter the pixel point is, the greater the compensation required is, and the over-compensation phenomenon is easy to occur, which leads to the bright region or the dark region on the display screen after the compensation. Based on this, the first region with a greater difference between the original brightness data and the reference brightness data is determined according to the first ratio of the pixel point in the embodiments of the present application, that is, the first region which is prone to over-compensation is determined, and the accuracy of the first region is higher.

[0102] Optionally, the step 2023 comprises: determining a plurality of target pixel points from the plurality of pixel points according to the first ratio of the plurality of pixel points, the first ratio of the target pixel points being greater than a first threshold or less than a second threshold, the first threshold being greater than the second threshold; and determining the first region according to the plurality of target pixel points, the first region comprising the target pixel points which are continuously distributed and are not less than a reference quantity.

[0103] For any pixel point, if the first ratio of the pixel point is greater than the first threshold, the pixel point is determined as a target pixel point; if the first ratio of the pixel point is less than the second threshold, the pixel point is determined as a target pixel point. The determination manner of the first threshold and the second threshold is not limited herein. Exemplarily, the first threshold and the second threshold are values set according to artificial experience, or the first threshold and the second threshold are values obtained through experimental verification. Generally, the first threshold is greater than 1, and the second threshold is less than 1, for example, the first threshold is 1.2, and the second threshold is 0.8.

[0104] It can be understood that on the display screen, the pixel points are arranged in M rows and N columns, and M and N are both positive integers, and any two target pixel points are adjacent or not adjacent. In the present example, it is assumed that the distance between two target pixel points is the minimum value of distance 1 and distance 2, wherein distance 1 is the number of pixel points between the two target pixel points in a row, and distance 2 is the number of pixel points between the two target pixel points in a column. The distance between two adjacent target pixel points is 0. Based on this, if the distance between two target pixel points is not greater than a distance threshold, the two target pixel points are continuously distributed. The distance threshold is a value input by a user or a randomly generated value, for example, the distance threshold is 0.

[0105] Each target pixel point can be traversed to determine a plurality of groups of continuously distributed target pixel points from the target pixel points. For any group of continuously distributed target pixel points, if the number of target pixel points is not less than a reference quantity, a first region is determined based on the group of continuously distributed target pixel points. The reference quantity can be a value set according to artificial experience, or the reference quantity is a value determined according to the number of pixel points on the display screen, for example, the reference quantity is 10% of the number of pixel points in a row (or a column) on the display screen.

[0106] It can be understood that, since the first ratio is a result of dividing the original luminance data by the reference luminance data. Therefore, if the first ratio is greater than the first threshold, it indicates that the original luminance data is greater than the reference luminance data, and since the target pixel point is bright, the target pixel point can be determined as a bright pixel point. In actual application, a first region can be determined for the bright pixel point, which can be referred to as a bright region. Correspondingly, if the first ratio is less than the second threshold, it indicates that the original luminance data is less than the reference luminance data, and since the target pixel point is dark, the target pixel point can be determined as a dark pixel point. In actual application, a first region can be determined for the dark pixel point, which can be referred to as a dark region. When determining the first region, the bright pixel point and the dark pixel point need to be traversed respectively, and optionally, the traversal is in order according to rows or columns.

[0107] Exemplarily, as shown in FIG. 5, when determining the bright region and the dark region to be adjusted, step 501 can be performed first, the display screen displaying a specified image is shot by an industrial camera to obtain original luminance data of each pixel point. Then step 502 is performed, the first ratio between the original luminance data of each pixel point and the average luminance data of the intermediate region is calculated. Then step 503 is performed, the bright pixel point with the first ratio greater than 1.2 and the dark pixel point with the first ratio less than 0.8 are found. After that, on one hand, step 504 is performed, the continuously distributed bright pixel points are found row by row (or column by column), and if the continuously distributed bright pixel points in a row (or a column) account for 10% of the number of pixel points in the row (or the column), the bright region is determined based on the continuously distributed bright pixel points. On the other hand, step 505 is performed, the continuously distributed dark pixel points are found row by row (or column by column), and if the continuously distributed dark pixel points in a row (or a column) account for 10% of the number of pixel points in the row (or the column), the dark region is determined based on the continuously distributed dark pixel points. The implementation manners of the above steps are described in the foregoing, and will not be described here again.

[0108] In actual application, after the luminance compensation, if there is over-compensation of individual pixel points on the display screen, in general, it does not affect the viewing experience of the user. Only when there is range over-compensation on the display screen, the viewing experience of the user will be affected. Based on this, the embodiment of the present application determines the first region, adjusts the luminance data of the first region, prevents over-compensation of the first region, that is, can reduce the number of pixel points that need to be adjusted, improves the adjustment efficiency, and also ensures the viewing experience of the user.

[0109] In step 203, the luminance data of the first region is adjusted according to a second region adjacent to the first region on the display screen, to obtain an adjusted first region, and the difference between the luminance data of the adjusted first region and the second region is less than the difference between the luminance data of the first region before adjustment and the second region.

[0110] In the embodiments of the present application, the second region includes at least one of the following: a plurality of columns of pixel points on the left side of the first region on the display screen; a plurality of columns of pixel points on the right side of the first region on the display screen; a plurality of rows of pixel points on the upper side of the first region on the display screen; and a plurality of rows of pixel points on the lower side of the first region on the display screen. The second region does not include the target pixel point. Since the target pixel point includes the bright pixel point and the dark pixel point, the pixel point that neither belongs to the bright pixel point nor belongs to the dark pixel point can be referred to as a normal pixel point. The second region includes a plurality of normal pixel points. By adjusting the luminance data of the first region through the second region, the luminance data of the bright pixel point and the luminance data of the dark pixel point can be close to the luminance data of the normal pixel point, so that the luminance data of the adjusted first region is close to the luminance data of the second region, and the difference between the luminance data of the first region and the luminance data of the second region is reduced.

[0111] There are various ways to adjust the luminance data of the first region according to the second region, for example, the luminance data of each pixel point in the first region can be adjusted pixel by pixel according to the second region. Alternatively, the luminance data of each pixel point in the first region can be adjusted cell by cell according to the second region to speed up the adjustment efficiency. The cell-by-cell adjustment method will be described in detail below, and other adjustment methods such as the pixel-by-pixel adjustment method will not be described herein.

[0112] In a possible implementation, the first region includes a plurality of first cells, and the second region includes a plurality of second cells, and each first cell has an adjacent second cell. In this example, step 203 includes steps 2031 to 2032 (not shown in the figure).

[0113] In step 2031, for any first cell, the luminance data of the first cell is adjusted according to the adjacent second cell to obtain an adjusted first cell.

[0114] The first cell and the second cell each include a plurality of pixel points, and the number of pixel points included in the first cell and the number of pixel points included in the second cell can be the same or different. For example, the first cell includes two rows and two columns of pixel points, and the second cell also includes two rows and two columns of pixel points, or the first cell includes one row or one column of pixel points, and the second cell includes one pixel point.

[0115] Each first unit is adjacent to at least one second unit, and any two first units can be adjacent to the same or different second units. For example, as shown in FIG. 6, a first unit includes a row of pixels in the first area, and a first unit as indicated by reference numeral 601 includes three pixels. A second unit includes pixels adjacent to the first unit in the second area, and a second unit as indicated by reference numeral 602 includes one pixel. The luminance data of the first unit can be adjusted according to the second unit adjacent to the first unit, so that the luminance data of the pixels in the first unit approaches the luminance data of the pixels in the second unit, thereby making the luminance data of the adjusted first unit approach the luminance data of the second unit, reducing the difference between the luminance data of the first unit and the second unit, and thereby avoiding overcompensation.

[0116] Optionally, the first unit includes at least one first pixel, and the second unit includes at least one second pixel. Step 2031 includes: calculating an average value of the original luminance data of each first pixel in any first unit to obtain first luminance data; calculating an average value of the original luminance data of each second pixel in the second unit adjacent to any first unit to obtain second luminance data; and determining the adjusted luminance data of each first pixel in the adjusted first unit according to a second ratio between the first luminance data and the second luminance data.

[0117] In the embodiments of the present application, the sum of the original luminance data of each first pixel in the first unit can be calculated, and the calculation result is divided by the number of first pixels in the first unit to obtain an average value, which is the first luminance data. Similarly, the sum of the original luminance data of each second pixel in the second unit adjacent to the first unit can be calculated, and the calculation result is divided by the number of second pixels in the second unit to obtain an average value, which is the second luminance data. The first luminance data is divided by the second luminance data to obtain the second ratio, and the adjusted luminance data of each first pixel is determined according to the second ratio to obtain the adjusted first unit.

[0118] Optionally, assuming that the first luminance data is A and the second luminance data is B, the adjusted luminance data of each first pixel point is determined according to A / B. It can be understood that any two first units correspond to the same or different first luminance data, and any two second units correspond to the same or different second luminance data. As shown in FIG. 6, one first unit includes one row of pixel points in the first region, and then from top to bottom, the first luminance data of each first pixel point is A1 to A2800 in turn. One second unit includes one row of pixel points in the second region, and then from top to bottom, the second luminance data of each second pixel point is B1 to B2800 in turn. Based on this, any two first units correspond to the same or different second ratios, so that the luminance data of the two adjusted first units can be the same or different. Since the first luminance data can reflect the average luminance of the first unit, and the second luminance data can reflect the average luminance of the second unit, by adjusting the first unit through the second ratio between the first luminance data and the second luminance data, the luminance difference between the first unit and the second unit can be reduced, thereby avoiding the phenomenon of overcompensation.

[0119] In an example embodiment, according to the second ratio between the first luminance data and the second luminance data, the adjusted luminance data of each first pixel point in the adjusted first unit is determined, including: according to the second ratio between the first luminance data and the second luminance data, the maximum second ratio and the minimum second ratio, the adjusted luminance data of each first pixel point in the adjusted first unit is determined. Wherein, the maximum second ratio is the maximum value of the second ratio corresponding to each first unit, and the minimum second ratio is the minimum value of the second ratio corresponding to each first unit.

[0120] In the embodiment of the application, the electronic device can determine the maximum second ratio and the minimum second ratio from the second ratio corresponding to each first unit. For any first unit, according to the maximum second ratio and the minimum second ratio, the second ratio between the first luminance data of the first unit and the second luminance data of the second unit adjacent to the first unit is adjusted to obtain the adjusted second ratio. According to the second luminance data and the adjusted second ratio, the adjusted luminance data of each first pixel point in the adjusted first unit is determined.

[0121] It can be understood that the maximum second ratio and the minimum second ratio can reflect the luminance difference of the first region itself, and therefore, adjusting the luminance data of the first region according to the maximum second ratio and the minimum second ratio can reduce the luminance difference of the first region, thereby avoiding the phenomenon of overcompensation.

[0122] In the embodiment of the application, the adjusted luminance data of the first pixel point can be determined according to the following implementation mode 1 or 2, and the implementation mode 1 and the implementation mode 2 are described in turn as follows.

[0123] In implementation 1, the first luminance data is greater than the second luminance data. The adjusted luminance data of each first pixel in the adjusted first unit is determined according to the second ratio between the first luminance data and the second luminance data, the maximum second ratio and the minimum second ratio, including: adjusting the second ratio between the first luminance data and the second luminance data according to the maximum second ratio and the minimum second ratio to obtain a first adjustment ratio; and determining the adjusted luminance data of each first pixel in the adjusted first unit according to the first adjustment ratio.

[0124] If the first luminance data is greater than the second luminance data, it means that the luminance of the first region is higher than that of the second region, i.e., the first region is a bright region. If the first region is directly compensated for luminance by using related technologies, overcompensation may occur, resulting in dark spots in the compensated first region. Based on this, in the embodiments of the present application, the second ratio between the first luminance data and the second luminance data is adjusted according to the maximum second ratio and the minimum second ratio, so that the adjusted luminance data of the first pixel determined according to the adjusted second ratio (i.e., the first adjustment ratio) is smaller, so that the compensation data determined based on the adjusted luminance data is smaller, and then the original luminance data compensated by the compensation data will not appear overcompensation phenomenon, avoiding dark spots in the compensated first region.

[0125] In actual application, the adjustment range of the second ratio can be determined according to the display effect of the display screen. That is, after adjusting the second ratio, the adjusted luminance data of each first pixel in the first unit is determined based on the adjusted second ratio, and the compensation data is determined based on the adjusted luminance data, so as to compensate the original luminance data according to the compensation data. If the compensated first region still has dark spots, it means that there is still overcompensation phenomenon, and then the adjustment range of the second ratio can be increased; on the contrary, if the compensated first region has bright spots, the adjustment range of the second ratio can be reduced. In this way, the above process can be repeated multiple times until the display effect of the display screen meets the requirements.

[0126] Optionally, a first difference between the maximum second ratio and the minimum second ratio can be calculated, and a second difference between the maximum second ratio and the second ratio of any first unit, or a second difference between the second ratio of any first unit and the minimum second ratio can be calculated. The second ratio of the first unit is adjusted according to the ratio between the second difference and the first difference. In actual application, the weight can be determined according to the display effect of the display screen, and the ratio between the second difference and the first difference is weighted based on the weight, and the second ratio of the first unit is adjusted according to the weighted ratio, so as to control the adjustment range of the second ratio by the weight.

[0127] Exemplarily, according to the first luminance data and the second luminance data, the maximum second ratio and the minimum second ratio are determined, and the second ratio between the first luminance data and the second luminance data is adjusted according to the maximum second ratio and the minimum second ratio to obtain a first adjustment ratio. The second ratio is reduced to obtain a first adjustment ratio. A represents the first luminance data, and B represents the second luminance data, The second ratio is represented by v1, and the weight is represented by w1. The maximum second ratio is represented by v1max. The minimum second ratio is represented by v1min. The second difference is represented by v1diff. The first difference is represented by w1diff. After the first adjustment ratio is obtained, the first adjustment ratio can be multiplied by the second luminance data to obtain adjusted first luminance data. The adjusted first luminance data can be used as the adjusted luminance data of each first pixel point. Alternatively, according to the ratio between the original luminance data and the first luminance data of each first pixel point, the adjusted luminance data of each first pixel point is determined based on the adjusted first luminance data, so that the ratio between the original luminance data and the first luminance data of any first pixel point is equal to the ratio between the adjusted luminance data of the first pixel point and the adjusted first luminance data.

[0128] In the implementation 2, the first luminance data is less than the second luminance data. According to the second ratio between the first luminance data and the second luminance data, the maximum second ratio, and the minimum second ratio, the adjusted luminance data of each first pixel point in the adjusted first unit is determined, including: according to the maximum second ratio and the minimum second ratio, the second ratio between the first luminance data and the second luminance data is increased to obtain a second adjustment ratio; and according to the second adjustment ratio, the adjusted luminance data of each first pixel point in the adjusted first unit is determined.

[0129] If the first luminance data is less than the second luminance data, it indicates that the luminance of the first region is lower than the luminance of the second region, i.e., the first region is a darkening region. If the first region is directly compensated for luminance by using related technologies, overcompensation may occur, resulting in bright spots in the compensated first region. Based on this, in the embodiments of the present application, according to the maximum second ratio and the minimum second ratio, the second ratio between the first luminance data and the second luminance data is increased, so that the adjusted luminance data of the first pixel point determined according to the increased second ratio (i.e., the second adjustment ratio) is larger, so that the compensation data determined based on the adjusted luminance data is smaller, and further, the original luminance data compensated by the compensation data does not appear overcompensation, avoiding bright spots in the compensated first region.

[0130] In practical applications, the increasing magnitude of the second ratio can be determined according to the display effect of the display screen. That is, after the second ratio is increased, the adjusted luminance data of each first pixel point in the first unit is determined based on the increased second ratio, and the compensation data is determined based on the adjusted luminance data, so as to compensate the original luminance data according to the compensation data. If bright spots still appear in the compensated first region, it means that there is still overcompensation, and the increasing magnitude of the second ratio can be increased; on the contrary, if dark spots appear in the compensated first region, the increasing magnitude of the second ratio can be decreased. In this way, the above process can be repeated multiple times until the display effect of the display screen meets the requirements.

[0131] Alternatively, a first difference between the maximum second ratio and the minimum second ratio can be calculated, and a second difference between the maximum second ratio and the second ratio of any first unit, or a second difference between the second ratio of any first unit and the minimum second ratio can be calculated. The second ratio of the first unit is increased according to the ratio between the second difference and the first difference. In practical applications, the weight can be determined according to the display effect of the display screen, the ratio between the second difference and the first difference is weighted based on the weight, and the second ratio of the first unit is increased according to the weighted ratio, so as to control the increasing magnitude of the second ratio by the weight.

[0132] Exemplarily, the second ratio of the first unit is increased by a second difference between the maximum second ratio and the minimum second ratio, and the second ratio of the first unit is increased by a ratio between the second difference and a first difference between the maximum second ratio and the minimum second ratio. The second ratio is increased to obtain a second adjusted ratio. Wherein, A represents the first luminance data, B represents the second luminance data, represents the second ratio, v2 is the weight, is the maximum second ratio, is the minimum second ratio. is the second difference, is the first difference. Wherein, v1 can be the same as or different from v2. After obtaining the second adjusted ratio, the second adjusted ratio can be multiplied by the second luminance data to obtain the adjusted first luminance data. The adjusted first luminance data can be used as the adjusted luminance data of each first pixel point. Alternatively, the adjusted luminance data of each first pixel point is determined based on the adjusted first luminance data according to the ratio between the original luminance data and the first luminance data of each first pixel point, so that the ratio between the original luminance data and the first luminance data of any first pixel point is equal to the ratio between the adjusted luminance data of the first pixel point and the adjusted first luminance data.

[0133] Step 2032, determining the adjusted first region according to the plurality of adjusted first units.

[0134] The process of adjusting the luminance data of the first region will be described in detail below in conjunction with FIG. 7.

[0135] Firstly, as shown in (1) of FIG. 7, the first region and the second region are adjacent, assuming that a first unit includes a row of pixel points in the first region, a second unit includes a row of pixel points in the second region, and there is an adjacent second unit for each first unit, then: a first first unit includes pixel points with original luminance data of 1300, 1200, 1300 in turn, and an adjacent second unit includes a pixel point with luminance data of 2400; a second first unit includes pixel points with original luminance data of 1300, 1200, 1300 in turn, and an adjacent second unit includes a pixel point with luminance data of 2405; and so on, which will not be described herein again.

[0136] Next, as shown in (2) of FIG. 7, the average value of the original luminance data of each pixel point in the first unit can be calculated to obtain first luminance data, such as the first luminance data of the first first unit and the second first unit is 1267, and so on.

[0137] Then, as shown in (3) of FIG. 7, for any first unit, assuming that the first luminance data is represented by parameter A and the second luminance data is represented by parameter B, then: the ratio A / B between the first luminance data and the second luminance data is calculated, and the minimum value (A / B)min and the maximum value (A / B)max are determined from each A / B. Since the first luminance data is less than the second luminance data, A / B can be adjusted according to (A / B)min, (A / B)max and weight v=0.3.

[0138] After that, as shown in (4) of FIG. 7, for any first unit, the adjusted A / B is multiplied by the second luminance data to obtain the adjusted first luminance data. As compared with (2) and (4) of FIG. 7, the adjusted first luminance data is closer to the second luminance data than the first luminance data. The adjusted first luminance data is the adjusted luminance data of each pixel point in the first unit.

[0139] In step 204, the compensation data of the plurality of pixel points is determined according to the adjusted first region and the remaining region on the display screen except the first region.

[0140] The compensation data of each pixel point on the display screen can be determined according to the adjusted luminance data of each pixel point in the adjusted first region and the original luminance data of each pixel point in the remaining region according to any compensation algorithm. The type of the compensation algorithm is not limited in the embodiments of the present application, and the compensation algorithm is exemplarily the Demura compensation algorithm, which will not be described herein again.

[0141] In the related art, as shown in (1) of FIG. 8, the electronic device can acquire the original brightness data of each pixel point through the industrial camera, and then calculate the compensation data of each pixel point according to the original brightness data of each pixel point using the Demura algorithm. In the embodiment of the present application, as shown in (2) of FIG. 8, the electronic device can acquire the original brightness data of each pixel point through the industrial camera. Then, the first region is identified according to the original brightness data of each pixel point, and a row of pixel points in the first region is taken as a first unit. The ratio between the average brightness data (i.e., the first brightness data) of the first unit and the brightness data (i.e., the second brightness data) of the adjacent pixel points is calculated. The ratio is adjusted according to the maximum value and the minimum value of the ratio, and the adjusted brightness data of each pixel point in the first region is determined according to the adjusted ratio. Then, the compensation data of each pixel point is calculated according to the adjusted brightness data of each pixel point in the first region and the original brightness data of each pixel point in the remaining region.

[0142] In step 205, the original brightness data of each pixel point is compensated based on the compensation data of each pixel point.

[0143] That is, for any pixel point, the original brightness data of the pixel point is compensated using the compensation data of the pixel point to obtain the compensated brightness data of the pixel point. Since the adjusted brightness data of the first region approaches the brightness data of the second region, the difference between the brightness data of the first region and the brightness data of the second region is reduced, thereby reducing the compensation data and avoiding the phenomenon of over-compensation, so as to avoid the occurrence of bright spots and dark blocks on the display screen. As shown in FIG. 9, after the display screen is compensated for brightness according to the method of the embodiment of the present application, no bright spots and dark blocks appear on the display screen, and the display effect is improved.

[0144] It should be noted that the information (including but not limited to user device information, user personal information, etc.), data (including but not limited to data for analysis, stored data, displayed data, etc.) and signals involved in the present application are all authorized by the user or fully authorized by all parties, and the collection, use and processing of related data need to comply with relevant laws, regulations and standards in relevant regions. For example, the original brightness data and the like involved in the present application are acquired under sufficient authorization.

[0145] The method can automatically identify the first area of the display screen, adjust the luminance data of the first area according to a second area adjacent to the first area on the display screen, reduce the difference in luminance data between the first area and the second area, and make the adjusted luminance data of the first area closer to the luminance data of the second area, thereby reducing the compensation required by each pixel point in the first area. Since the compensation of each pixel point in the first area is small, the original luminance data of the pixel point can be compensated by the compensation data of the pixel point, which can prevent overcompensation, reduce the possibility of bright spots and dark blocks on the display screen, improve the display effect, and improve the viewing experience of the user.

When the pressure sensor 1113 is arranged at the lower layer of the display screen 1105, the operable control on the UI interface can be controlled by the processor 1101 according to the pressure operation of the user to the display screen 1105. The operable control includes at least one of a button control, a scroll bar control, an icon control, and a menu control.

[0181] The optical sensor 1114 is used to collect the ambient light intensity. In an embodiment, the processor 1101 can control the display brightness of the display screen 1105 according to the ambient light intensity collected by the optical sensor 1114. Specifically, when the ambient light intensity is high, the display brightness of the display screen 1105 is increased; when the ambient light intensity is low, the display brightness of the display screen 1105 is decreased. In another embodiment, the processor 1101 can also dynamically adjust the shooting parameter of the camera assembly 1106 according to the ambient light intensity collected by the optical sensor 1114.

[0182] The proximity sensor 1115, also known as a distance sensor, is usually arranged at the front panel of the terminal device 1100. The proximity sensor 1115 is used to collect the distance between the user and the front of the terminal device 1100. In an embodiment, when the proximity sensor 1115 detects that the distance between the user and the front of the terminal device 1100 gradually decreases, the display screen 1105 is switched from the bright screen state to the off-screen state by the processor 1101; when the proximity sensor 1115 detects that the distance between the user and the front of the terminal device 1100 gradually increases, the display screen 1105 is switched from the off-screen state to the bright screen state by the processor 1101.
