The device can be implemented in software and / or hardware, and the device can be configured in an electronic device, which can include but is not limited to a terminal, a server, etc.

[0032] As Figure 1 shown, the control method for the display screen includes:

[0033] S101: Obtain first display data, where the first display data is data to be correspondingly displayed in a first display area.

[0034] The display screen of the electronic device can be an Organic Light-Emitting Diode (OLED) display screen. The local display area corresponding to the under-screen camera device in the display screen of the electronic device can be referred to as the first display area. The display screen can specifically be the display screen of a smartphone, a smart TV with a camera module, a smart watch, etc. Corresponding to the first display area, the other display areas in the display screen except the first display area can be referred to as the second display area. As Figure 2 shown, Figure 2 It is a schematic diagram of a display area proposed in an embodiment of the present disclosure. The first display area can be the display area corresponding to the under-screen camera device in the electronic device, or the under-screen fingerprint recognition module display area, the under-screen physical button display area, etc., and there is no limitation thereto.

[0035] The data to be displayed in the first display area can be referred to as the first display data, and the first display data can be data containing display information such as color and saturation in the first display area.

[0036] When obtaining the first display data in the embodiments of the present disclosure, it may be to obtain a display image to be displayed in the overall display area in the background of the electronic device, disassemble the image data to be displayed in the first display area from the display image, and use the image data as the first display data. Alternatively, any other possible method may be used to obtain the first display data, and this is not limited.

[0037] S102: Perform compensation processing on the first display data to obtain target display data.

[0038] In the embodiments of the present disclosure, the display brightness requirement for the display screen may be referred to (the display brightness requirement may be determined by analyzing the configured display brightness value for the display screen, and this is not limited). The first display data is compensated according to the display brightness requirement, and the compensated display data is used as the target display data. That is to say, when the compensated target display data is correspondingly displayed in the first display area, the brightness situation when the first display area displays the target display data can meet the above-mentioned display brightness requirement.

[0039] When compensating the first display data in the embodiments of the present disclosure, it may be to use digital image processing technology to compensate the first display data according to the image information such as color and contrast of the display images in the first display area and the second display area, and compensate the image information in the first display area to make it have the same visual effect as the image information in the second display area, so as to obtain the target display data.

[0040] When compensating the first display data in the embodiments of the present disclosure, it may also be to use an image acquisition tool such as an optical sensor to obtain the information of the display image, compare the image information of the first display area and the second display area to obtain the difference information between the first display area and the second display area, monitor the difference information, and then compensate the first display data by means of a digital model or manual debugging until the difference information meets the image effect requirement, and use the compensated first display data as the target display data.

[0041] S103: Display the target display data in the first display area, where the first brightness information when the first display area displays the target display data meets the brightness condition.

[0042] Among them, the brightness information correspondingly displayed when the target display data is displayed in the first display area may be referred to as the first brightness information. The first brightness information may specifically be the brightness value, saturation, color, etc. when the target display data is displayed in the first display area, and this is not limited.

[0043] In the embodiments of the present disclosure, after compensating the first display data to obtain the target display data, the target display data can be displayed in the first display area. When the target display data is displayed in the first display area, the brightness information of the second display area can be obtained, and the first brightness information of the first display area can be adjusted so that the first brightness information meets the preset brightness condition. The brightness condition can be, for example, that when the target display data is displayed in the first display area, the brightness value difference from when the corresponding display data is displayed in the second display area is less than a preset brightness value or percentage, etc., and there is no limitation on this.

[0044] In this embodiment, by obtaining the first display data, which is the data to be correspondingly displayed in the first display area, and then compensating the first display data to obtain the target display data, and then displaying the target display data in the first display area. Among them, the first brightness information when the target display data is displayed in the first display area meets the brightness condition. Since the first display data is compensated in advance, the brightness information of the first display area meets the brightness requirement, so that the display data of the display area corresponding to the under-screen camera device can be compensated in advance to assist in enhancing the visual consistency of different display areas of the display screen, and then effectively optimize the overall display visual effect of the electronic device.

[0045] Figure 3 It is a schematic flowchart of a control method for a display screen proposed in another embodiment of the present disclosure.

[0046] Such as Figure 3 shown, the control method of the display screen includes:

[0047] S301: Obtain the data to be displayed, which is the data to be correspondingly displayed in the overall display area.

[0048] Among them, the data to be displayed can be video frame data, image data, text data, etc. to be displayed in the overall display area of the display screen, and there is no limitation on this.

[0049] In the embodiments of the present disclosure, when obtaining the data to be displayed, it can be the data to be displayed that is captured by the background server corresponding to the electronic device (for example, read from a database, received from other electronic devices, etc.) and is about to be transmitted to the display screen.

[0050] After obtaining the data to be displayed corresponding to the overall display area as described above, the corresponding data splitting can be performed on the data to be displayed to determine the first display data and the second display data.

[0051] S302: Analyze the data to be displayed to obtain the first display data and the second display data, where the second display data is the data to be correspondingly displayed in the second display area.

[0052] In the embodiments of the present disclosure, the first display data and the second display data may have the same or different encoding methods. When parsing the data to be displayed, the overall coordinates of the display screen can be determined, and the local coordinates corresponding to the first display area and the second display area in the overall coordinates can be determined respectively. According to the local coordinates, the data to be displayed can be disassembled accordingly to obtain the first display data and the second display data. Alternatively, the overall size data of the display screen and the local size data of the first display area corresponding to the under-screen camera device can also be used to divide the data to be displayed to obtain the first display data and the second display data, and there is no limitation on this.

[0053] S303: Perform compensation processing on the first display data to obtain the target display data.

[0054] For the description of S303, reference can be specifically made to the above embodiments, and details will not be repeated here.

[0055] In the embodiments of the present disclosure, the method of processing and displaying the data to be displayed can be as Figure 4 shown. Figure 4 FIG. 14 is a schematic diagram of the processing flow of the data to be displayed proposed in another embodiment of the present disclosure. Among them, the electronic device can obtain the data to be displayed from the wireless access point and transmit it to the driving integrated circuit of the display screen through the data interface. The driving integrated circuit parses the data to be displayed to obtain the first display data and the second display data, and performs optical compensation processing on the first display data accordingly to obtain the target display data, and then projects the target display data onto the first display area and projects the second display data onto the second display area to complete the display processing of the data to be displayed on the entire display screen. For details, reference can be made to the following embodiments.

[0056] S304: Display the target display data in the first display area and display the second display data in the second display area, where the brightness difference between the first brightness information and the second brightness information is less than the difference threshold, and the second brightness information is the brightness information when the second display data is displayed in the second display area.

[0057] Among them, the brightness and other information of the image included in the second display data displayed in the second display area can be referred to as the second brightness information. The second brightness information can specifically be the brightness value, saturation, color, etc. displayed correspondingly when the second display data is displayed in the second display area, and there is no limitation on this.

[0058] In the embodiments of the present disclosure, the threshold of the brightness difference between the first brightness information and the second brightness information can be preset. The threshold of the brightness difference can be referred to as the difference threshold. The difference threshold of the brightness difference can be the threshold value of the brightness difference that enables the first display area and the second display area to meet the visual effect display consistency.

[0059] Therefore, in the process of actual display control processing in the present disclosure embodiments, corresponding compensation data can be performed on the first display data according to the difference threshold, so that the first brightness information when the first display area displays the target display data after display compensation processing and the second brightness information when the second display area displays the second display data can have a brightness difference less than the difference threshold.

[0060] In the present disclosure embodiments, a difference threshold between the first brightness information and the second brightness information is preset in advance. After compensating the first display data, target display data that meets the difference threshold can be obtained, and then the target display data can be triggered to be displayed in the first display area, and the second display data can be displayed in the second display area.

[0061] For example, in an application scenario where the display screen is an Organic Light-Emitting Diode (OLED) panel, the preset difference threshold of the brightness difference is 5 nits. When the second brightness information of the second display area is measured to be 485 nits, the first brightness information of the first display area is 475 nits to 480 nits. At this time, it is determined that the first brightness information and the second brightness information do not meet the difference threshold of the brightness difference. After performing the compensation processing on the first display data in advance in the present disclosure embodiments to obtain the target display data, the brightness difference between the first brightness information when the target display data is displayed in the first display area and the second brightness information when the second display data is displayed in the second display area can be less than 5 nits, thus meeting the brightness display requirements of the display screen and making the visual display effect of the display screen meet the consistency.

[0062] In this embodiment, by obtaining the data to be displayed, which is the data to be correspondingly displayed in the overall display area, parsing the data to be displayed to obtain the first display data and the second display data, where the second display data is the data to be correspondingly displayed in the second display area, performing compensation processing on the first display data to obtain the target display data, displaying the target display data in the first display area, and displaying the second display data in the second display area. Among them, the brightness difference between the first brightness information and the second brightness information is less than the difference threshold, and the second brightness information is the brightness information when the second display data is displayed in the second display area. Since the data to be displayed is obtained and the first display data and the second display data are parsed, it can effectively assist in pre-compensating the first display data to be displayed in the first display area, and can timely ensure the consistency of the subsequent display visual effect of the display screen, facilitating the debugging and compensation of the brightness difference when displaying the corresponding display data in different display areas. Since the brightness difference between the first brightness information when the target display data is displayed in the first display area and the second brightness information when the second display data is displayed in the second display area is compared with the difference threshold, that is, the dimension of the brightness difference between different display areas is used to assist in measuring the pre-compensation processing effect of the first display data, it can effectively ensure that the pre-compensation processing method effectively meets the requirements of visual effect display consistency, can reasonably and effectively reduce the difference in the image display brightness dimension between the first display area and the second display area, optimize the overall display effect of the display screen, and improve the consistency of the overall visual display effect.

[0063] Figure 5 It is a schematic flowchart of the control method of the display screen proposed in another embodiment of the present disclosure.

[0064] As Figure 5 shown, the control method of the display screen includes:

[0065] S501: Obtain the first display data, where the first display data is the data to be correspondingly displayed in the first display area.

[0066] For the description of S501, reference can be specifically made to the above embodiment, which will not be elaborated here.

[0067] S502: Determine the brightness compensation coefficient.

[0068] Among them, the brightness compensation coefficient can be pre-calibrated and can be used as a reference when compensating the first display data.

[0069] In the embodiments of the present disclosure, the current brightness information of the first display area and the second display area can be detected respectively, and the brightness compensation coefficient can be determined from a plurality of pre-calibrated candidate compensation coefficients according to the brightness difference between the current brightness information of the first display area and the current brightness information of the second display area. Alternatively, any other possible method can be used to determine the brightness compensation coefficient, which is not limited herein.

[0070] Optionally, when determining the brightness compensation coefficient in the embodiments of the present disclosure, multiple gray scale values corresponding to the first display area can be determined, multiple gray scale levels to which the multiple gray scale values belong can be determined, and multiple brightness compensation coefficients corresponding to the multiple gray scale levels can be determined according to a preset relationship. The brightness compensation coefficient is used to perform brightness compensation on the display sub-areas corresponding to the corresponding gray scale values. The display sub-areas are local areas in the first display area. Since the distribution of the gray scale values in the first display area is referred to for assisting in determining the brightness compensation coefficient, the determined brightness compensation coefficient can be more accurate and more in line with the actual compensation scenario requirements. When the first display data is compensated with the brightness compensation coefficient determined according to the distribution of the gray scale values in the first display area, the visual display effect consistency of different display areas can be effectively guaranteed when the first display area displays the target display data after display compensation.

[0071] Among them, the gray scale change information between white and black in the first display area is pre-divided into several parts, and a value is set for each part (that is, quantization processing is performed on each part of the gray scale change information), and this value can be called a gray scale value.

[0072] For example, the gray scale values between pure white and pure black in the first display area can be set to 255 and 0 respectively, and the remaining gray scales are set with gray scale values according to the situation from white to black. At the same time, multiple adjacent gray scale values can be combined into the same gray scale level to represent the gray scale change in the first display area.

[0073] In the embodiments of the present disclosure, as Figure 6 shown, Figure 6 is a flowchart for calculating the brightness compensation coefficient proposed in another embodiment of the present disclosure. According to the gray scale values pre-set for the first display area, the first brightness information and the second brightness information in the case of the same gray scale value are compared to generate a brightness difference, and the brightness compensation coefficient is calculated from the brightness difference. Due to the differences in panel design and manufacturing processes between the first brightness area and the second brightness area, there may be a brightness difference between the first display area and the second display area in the case of the same gray scale value. For example, the overall brightness of the first display area is lower than that of the second display area. In order to eliminate the influence of this brightness difference on the display effect of the overall display screen, the brightness compensation coefficient can be set to compensate the brightness of different display areas in the case of the same gray scale value.

[0074] S503: Determine the initial compensation luminance value corresponding to the first display data.

[0075] In the embodiments of the present disclosure, when the display screen displays pure white or pure black, the luminance of the first display area and the second display area are respectively statistically analyzed, and the first display data is compensated according to the statistical results until the luminance of the first display area and the second display area meets the conditions. The compensated luminance value can be referred to as the initial compensation luminance value.

[0076] In the embodiments of the present disclosure, when determining the initial compensation luminance value, it can be determined according to the luminance difference between the first display data and the second display data under the same gray scale value, or the initial compensation luminance value corresponding to the first display data can be obtained through mathematical calculation based on the materials, processes, etc. of the first display area and the second display area, and there is no limitation thereto.

[0077] S504: Process the first display data according to the luminance compensation coefficient and the initial compensation luminance value to obtain the target display data.

[0078] In the embodiments of the present disclosure, the luminance difference between different display areas changes with the change of the gray scale value. For example, as Figure 7 shown, Figure 7 is a schematic diagram of the change of the luminance difference between different display areas with the change of the gray scale value proposed in another embodiment of the present disclosure. Due to the increase of the gray scale value, the luminance difference is inversely proportional to the change of the gray scale value. The gray scale level and the corresponding luminance compensation coefficient are preset, and then the first display data to be displayed in the first display area is compensated according to the preset relationship.

[0079] In the embodiments of the present disclosure, the first display data in the first display area can be compensated by the luminance compensation coefficient and the initial compensation luminance value, so that the visual effect of the display luminance of the compensated target display data in the first display area is consistent with the visual effect of the display luminance of the second display area.

[0080] Optionally, the brightness compensation coefficient and the initial compensation brightness value can be multiplied to obtain the target compensation brightness value; the brightness of the first display data is compensated according to the target compensation brightness value to obtain the target display data. Since the calculation is performed on the brightness compensation coefficient and the initial compensation brightness value, and the brightness of the first display data is compensated according to the calculation result, the difference between the brightness value of the first display data and the brightness value of the second display data under the same gray scale level is reduced. At the same time, the brightness compensation coefficient can calculate the brightness difference of different gray scale levels to obtain the compensated brightness value under different gray scale levels, so that the compensation processing logic for the first display data can effectively adapt to the personalized compensation requirements of different gray scale levels in the first display area, making the compensation processing logic more targeted and effectively improving the compensation processing effect.

[0081] In the embodiments of the present disclosure, as Figure 8 shown, Figure 8 FIG. is a schematic diagram of the target display data calculation process proposed in another embodiment of the present disclosure. In the optical compensation link, optical compensation is performed on the first display area to obtain the target display data. The calculation formula of the target display data can be "target display data = first display data + initial compensation brightness value × brightness compensation coefficient", which can effectively reduce the visual brightness difference caused by reasons such as panel design and manufacturing process, and effectively improve the convenience and applicability of the compensation process, improve the timeliness of the compensation process, avoid introducing display delay into the display process of the display screen by the compensation process, and ensure the coherence of the display.

[0082] S505: Display the target display data in the first display area, where the first brightness information when the target display data is displayed in the first display area satisfies the brightness condition.

[0083] For the description of S505, reference can be specifically made to the above embodiments and will not be elaborated here.

[0084] In this embodiment, by obtaining first display data, which is data to be correspondingly displayed in a first display area, determining a brightness compensation coefficient, determining an initial compensation brightness value corresponding to the first display data, processing the first display data according to the brightness compensation coefficient and the initial compensation brightness value to obtain target display data, and displaying the target display data in the first display area, wherein the first brightness information when the first display area displays the target display data meets the brightness condition. Since the calculation of the brightness compensation coefficient and the initial compensation brightness value is performed, and the brightness of the first display data is compensated according to the calculation result, the difference between the brightness value of the first display data and the brightness value of the second display data under the condition of the same gray scale level is reduced. At the same time, the brightness compensation coefficient can calculate the brightness difference of different gray scale levels to obtain the compensated brightness values under different gray scale level conditions, so that the compensation processing logic for the first display data can effectively adapt to the personalized compensation requirements of different gray scale levels in the first display area, making the compensation processing logic more targeted and effectively improving the compensation processing effect. Since the gray scale value distribution of the first display area is referred to for assisting in determining the brightness compensation coefficient, the determined brightness compensation coefficient can be more accurate and more in line with the actual compensation scenario requirements. When the first display data is compensated with the brightness compensation coefficient determined by referring to the gray scale value distribution of the first display area, it can effectively ensure the consistency of the visual display effects of different display areas when the first display area displays the compensated target display data. It can effectively reduce the visual brightness difference caused by reasons such as panel design and manufacturing process, while effectively improving the convenience and applicability of the compensation processing, enhancing the timeliness of the compensation processing, avoiding the introduction of display delay into the display processing flow of the display screen by the compensation processing flow, and ensuring the coherence of the display.

[0085] Figure 9 It is a schematic flowchart of a control method for a display screen proposed in another embodiment of the present disclosure.

[0086] As Figure 9 shown, the control method for the display screen includes:

[0087] S901: Perform sampling processing on the display screen of the display screen to obtain a sampled image.

[0088] Among them, the display screen can be an overall displayed image screen on the display screen, or it can also be a display screen in the sampled area of the display screen. The sampled area can be a pre-labeled area for sampling to obtain a sampled image, and there is no limitation on this.

[0089] When performing sampling processing on the display screen of the present disclosure embodiment, sampling areas can be selected in the display screen according to a certain sampling rule to generate a sampling image, or a part of the image displayed on the display screen can be randomly selected as the sampling image, and there is no limitation in this regard.

[0090] S902: According to the sampling image, determine a plurality of sampling brightness values and a plurality of sampling gray-scale values respectively corresponding to a plurality of pixel points of the display screen.

[0091] Among them, when selecting a plurality of pixel points of the sampling image, the brightness value and gray-scale value of the pixel points can be referred to as the sampling brightness value and sampling gray-scale value. For each of the plurality of pixel points collected during the sampling process, there can be a corresponding sampling brightness value and sampling gray-scale value, so as to obtain a plurality of sampling brightness values and a plurality of sampling gray-scale values respectively corresponding to a plurality of pixel points of the display screen.

[0092] In the present disclosure embodiment, when selecting a plurality of pixel points of the display screen, a certain proportion can be used to select a plurality of pixel points of the sampling image corresponding to the first display area and a plurality of pixel points of the sampling image corresponding to the second display area. After determining the pixel point positions, an image recognition tool or an image recognition algorithm can be used to measure a plurality of sampling brightness values and a plurality of sampling gray-scale values respectively corresponding to the plurality of pixel points.

[0093] S903: According to the plurality of sampling brightness values, determine the brightness difference information between the first display area and the second display area when the display screen displays the sampling image.

[0094] Among them, the data information used to represent the brightness difference between the first display area and the second display area in the sampling image can be referred to as the brightness difference information.

[0095] In the present disclosure embodiment, when determining the brightness difference information, it can be determined based on the plurality of sampling brightness values corresponding to the plurality of pixel points in different areas of the sampling image. The sampling brightness values of the plurality of pixel points with the same gray-scale value in different areas are compared to generate the brightness difference information of different display areas under the same gray-scale value.

[0096] S904: Perform level division on the plurality of sampling gray-scale values to obtain a plurality of gray-scale levels, and the plurality of gray-scale levels correspond to some of the sampling gray-scale values.

[0097] In the present disclosure embodiment, when dividing the plurality of gray-scale levels, the gray-scale values can be evenly divided into a plurality of gray-scale levels according to the magnitude distribution of the plurality of sampling gray-scale values, or the gray-scale values can be divided into a plurality of areas according to the actual display situation. There is no limitation on the number of gray-scale levels and the division of the gray-scale levels.

[0098] For example, according to the needs of the actual display effect, the gray scale values can be divided into five levels: "0 - 16", "16 - 32", "32 - 64", "64 - 128", and "128 - 255".

[0099] S905: Generate a plurality of brightness compensation coefficients respectively corresponding to a plurality of gray scale levels according to the brightness difference information.

[0100] In the embodiments of the present disclosure, as Figure 10 shown, Figure 10 is a schematic diagram of the brightness compensation coefficient proposed in another embodiment of the present disclosure. Since the brightness difference information between the first display area and the second display area is smaller in the case of high gray scale values and larger in the case of low gray scale values, the division of the gray scale levels has a large span in high gray scales and a small span in low gray scales. According to the differences in the brightness difference information at different gray scale levels, a plurality of brightness compensation coefficients respectively corresponding to a plurality of gray scale levels are determined.

[0101] S906: Generate a preset relationship according to a plurality of gray scale levels and a plurality of brightness compensation coefficients.

[0102] Among them, the relationship between the preset gray scale levels and the brightness compensation coefficients can be referred to as a preset relationship. According to the gray scale levels and the preset relationship, the brightness compensation coefficient at this gray scale level can be calculated.

[0103] In the embodiments of the present disclosure, a preset relationship between the gray scale levels and the brightness compensation coefficients can be generated according to the changes of a plurality of gray scale levels and a plurality of brightness compensation coefficients. For example, when the gray scale value increases, the brightness compensation coefficient decreases correspondingly. Mathematical formulas or models can also be used to describe the gray scale levels and a plurality of brightness compensation coefficients to generate a preset relationship, which is not limited herein.

[0104] S907: Obtain first display data, which is the data to be correspondingly displayed in the first display area.

[0105] For the description of S907, please refer to the above embodiments for details and will not be elaborated here.

[0106] S908: Determine the display sub - data to be displayed in the display sub - area.

[0107] Among them, the first display area can be divided to generate a plurality of sub - areas, which can be referred to as display sub - areas. The data to be displayed in the display sub - area can be referred to as display sub - data. The display sub - data can be part of the first display data. That is to say, according to the relative size relationship and relative spatial position relationship between each display sub - area and the first display area, the first display data can be correspondingly pixel - divided to obtain the display sub - data to be displayed in the display sub - area.

[0108] In the embodiments of the present disclosure, when dividing the first display area to obtain display sub-areas, the first display area can be evenly divided into multiple sub-areas, or the first display area can be divided according to actual display needs, and the first display data to be displayed in the first display area is divided into display sub-data corresponding to each display sub-area to obtain multiple display sub-data.

[0109] S909: Perform compensation processing on the display sub-data according to the brightness compensation coefficient corresponding to the display sub-area to obtain target display sub-data.

[0110] Among them, the display sub-data after optical compensation of the first display area can be referred to as target display sub-data.

[0111] In the embodiments of the present disclosure, the corresponding brightness compensation coefficient is determined according to the gray level of the pixel points in the display sub-area, and then the target display sub-data is generated according to the brightness compensation coefficient, the initial compensation brightness value corresponding to the display sub-area, and the display sub-data.

[0112] S910: Synthesize the multiple target display sub-data to obtain target display data.

[0113] In the embodiments of the present disclosure, the multiple target display sub-data are synthesized according to the division of the corresponding display sub-areas to generate the target display data corresponding to the first display area.

[0114] In the embodiments of the present disclosure, as Figure 11 shown, Figure 11 is a schematic diagram showing the change of the brightness difference of the compensated display area with the gray level in another embodiment of the present disclosure. In all gray level pictures with the brightness difference between the first display area and the second display area in the gray level value range of 0 to 255, the compensated brightness difference is relatively reduced and tends to be stable, improving the overall visual effect of the display screen.

[0115] S911: Display the target display data in the first display area, where the first brightness information when the first display area displays the target display data satisfies the brightness condition.

[0116] For the description of S911, specific reference can be made to the above embodiments, which will not be elaborated here.

[0117] In this embodiment, the display screen's display image is sampled to obtain a sampled image. Based on the sampled image, multiple sampled brightness values and multiple sampled gray-scale values corresponding to multiple pixel points of the display screen are determined. According to the multiple sampled brightness values, the brightness difference information between the first display area and the second display area when the display screen shows the sampled image is determined. The multiple sampled gray-scale values are classified into levels to obtain multiple gray-scale levels, and the multiple gray-scale levels correspond to some of the sampled gray-scale values. According to the brightness difference information, multiple brightness compensation coefficients corresponding to the multiple gray-scale levels are generated. Based on the multiple gray-scale levels and the multiple brightness compensation coefficients, a preset relationship is generated. Then, first display data is obtained. The first display data is the data to be correspondingly displayed in the first display area. After that, the display sub-data to be displayed in the display sub-area is determined. According to the brightness compensation coefficient corresponding to the display sub-area, the display sub-data is compensated to obtain the target display sub-data. According to the multiple target display sub-data, the target display data is synthesized, and the target display data is displayed in the first display area. Among them, the first brightness information when the target display data is displayed in the first display area meets the brightness condition. Since the display screen's display image is sampled to generate a sampled image, and the corresponding brightness difference information and gray-scale levels are determined based on the sampled image, the accuracy of determining the brightness difference information and gray-scale levels of the display screen is improved. At the same time, the brightness compensation coefficient is made more objective, and the accuracy of the brightness compensation coefficient in different gray-scale levels is improved. Then, a preset relationship is determined according to the multiple brightness compensation coefficients, and the use of the preset relationship enhances the convenience of determining the target display data. Since the first display data is divided into multiple display sub-areas, the data of the multiple display sub-areas is determined, and their brightness is compensated respectively, the pertinence of the brightness compensation in the first display area is improved, meeting the personalized compensation needs of different display sub-areas, effectively improving the compensation effect for each display sub-data, and further enhancing the matching of the visual display effects between the first display area and the second display area.
