[0049] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0050] In an exemplary embodiment of the present disclosure, in order to overcome the problem of inconsistent visual effects of screen display before and after screen replacement in the related art, a screen display method is provided, including: after the first screen of the electronic device is removed and replaced with the second screen, obtaining an image to be displayed; obtaining first compensation data and second compensation data, the first compensation data is used to compensate for the display abnormality of the second screen caused by aging of the first screen, and the second compensation data is used to compensate for the display abnormality of the second screen caused by the production process of the second screen; based on the first compensation data and the second compensation data, adjusting the brightness parameters of the image to be displayed to obtain a target image; displaying the target image. This method can ensure that the visual effect of the display of the first screen of the electronic device before and after the screen is replaced is consistent with the visual effect of the display of the second screen, and the visual effect of the display of all pixels of the second screen is consistent, thereby improving the user experience.

[0051] In an exemplary embodiment of the present disclosure, a screen display method is provided, which is applied to an electronic device. Figure 1 is a flow chart of a screen display method according to an exemplary embodiment. Figure 1 As shown, the following steps are included:

[0052] Step S101: after a first screen of an electronic device is removed and replaced with a second screen, an image to be displayed is acquired.

[0053] Optionally, the electronic device includes a smart phone, a tablet, a laptop, a display, a smart screen, a smart TV, a smart wearable device, an IoT device, a smart car machine, and other devices with a display panel, wherein the display panel may be an LED display panel, including various types of organic light-emitting diode (OLED) display panels, such as active-matrix OLED (AMOLED) display panels and passive-matrix OLED (PMOLED) display panels, and also other types of LED display panels; the display panel may also be a display panel using other display technologies, and its display effect may change with the increase of usage time. In some embodiments, the display panel may also be referred to as a screen.

[0054] The first screen is the original screen of the electronic device that has been used for a period of time, and the second screen is a new screen that has not been used since leaving the factory. The first screen of the electronic device is removed and replaced with the second screen. After replacing with the second screen, the image to be displayed is any image that needs to be displayed after the electronic device is turned on, such as an image corresponding to any user interface, any picture in the wallpaper, or any frame in the video.

[0055] Step S102, obtaining first compensation data and second compensation data, the first compensation data being used to compensate for display abnormality of the second screen caused by aging of the first screen, and the second compensation data being used to compensate for display abnormality of the second screen caused by the production process of the second screen.

[0056] After the first screen of the electronic device is removed and replaced with the second screen, the display anomaly of the second screen includes two aspects: the first aspect is that the visual effect displayed on the second screen is inconsistent with the visual effect displayed on the first screen. As the screen is used for a longer period of time, the light-emitting device in the screen will continue to age, which will cause the overall display brightness of the screen to be low. Since the first screen is aged more seriously after being used for a period of time, and the second screen that has not been used after leaving the factory does not age, the overall display brightness of the first screen is lower than the overall display brightness of the second screen, resulting in the visual effect displayed on the second screen after the screen is replaced being inconsistent with the visual effect displayed on the first screen before the screen is replaced; the second aspect is the display defects of the second screen itself. In the production process of the second screen, the instability of factors such as manufacturing materials and process flow will cause the second screen to have display defects, such as uneven display brightness of the second screen, that is, the visual effects displayed by all pixels in the second screen are inconsistent. The first compensation data is used to solve the display anomaly of the second screen caused by the above-mentioned first aspect, that is, to compensate for the display anomaly of the second screen caused by the aging of the first screen, and the second compensation data is used to solve the display anomaly of the second screen caused by the above-mentioned second aspect, that is, to compensate for the display anomaly of the second screen caused by the production process of the second screen. In some implementations, if the second screen itself does not have display defects caused by the production process, the second compensation data is empty data.

[0057] The maintenance personnel may directly input the first compensation data and the second compensation data into the electronic device after replacing the second screen, or may input a method for obtaining the first compensation data and the second compensation data into the electronic device after replacing the second screen, and instruct the first screen of the electronic device to be removed and replaced with the second screen through a preset instruction. When the electronic device detects the preset instruction, it respectively obtains the first compensation data and the second compensation data through the received acquisition method, for example, the acquisition method includes requesting a cloud server or calculating through a preset calculation method.

[0058] Step S103: adjusting the brightness parameter of the image to be displayed based on the first compensation data and the second compensation data to obtain a target image.

[0059] By compensating the brightness parameters of each pixel of the image to be displayed, compensation for the second screen is achieved to eliminate the display anomaly of the second screen. For example, the brightness of the preset pixel of the image to be displayed is 15 nits, the preset pixel is displayed at a preset position on the screen, the first screen includes a first pixel, the second screen includes a second pixel, the relative position of the first pixel in the first screen is the same as the relative position of the second pixel in the second screen, both are preset positions, when the image to be displayed is displayed before the first screen is removed, the display brightness when the preset pixel is displayed through the first pixel of the first screen is 10nit, and when the second screen displays the image to be displayed, the display brightness when the preset pixel is displayed through the second pixel of the second screen is 15nit, at this time, in order to ensure that the display effect of the second screen is consistent with that of the first screen, the brightness of the preset pixel of the image to be displayed can be adjusted to 10nit. For another example, the brightness of the first preset pixel point of the image to be displayed and the second preset pixel point of the image to be displayed are both 15nit, the first preset pixel point is displayed at the first position of the second screen, and the display brightness at the first position is 13nit, the second preset pixel point is displayed at the second position of the second screen, and the display brightness at the second position is 15nit. At this time, in order to ensure consistent display effects at all positions of the second screen, the brightness of the first preset pixel point can be adjusted to 17nit or the brightness of the second preset pixel point can be adjusted to 13nit.

[0060] The brightness parameter of each pixel of the image to be displayed is a parameter that affects the brightness of each pixel of the image to be displayed. In some embodiments, the display parameter is a grayscale value or a three-primary color component value (i.e., R value, G value, and B value), and the grayscale value or the three-primary color component value is positively correlated with the brightness. The larger the grayscale value or the larger the three-primary color component value, the brighter the image. In some embodiments, the image to be displayed is gray-scaled to obtain the grayscale value of each pixel of the image to be displayed, and the grayscale value of each pixel of the image to be displayed is adjusted according to the first compensation data and the second compensation data, and the adjusted image to be displayed is the target image. In some embodiments, the three-primary color component value of each pixel of the image to be displayed is obtained, and the three-primary color component value of each pixel of the image to be displayed is adjusted according to the first compensation data and the second compensation data, and the adjusted image to be displayed is the target image.

[0061] When adjusting according to the first compensation data, ensure that the display brightness of the image to be displayed through the second screen is the same as the display brightness of the image to be displayed through the first screen, and the first compensation data corresponding to each pixel of the image to be displayed is the same; when adjusting according to the second compensation data, ensure that the display brightness of different pixel points of the second screen is the same, and the second compensation data corresponding to each pixel point of the image to be displayed may be the same or different, and is determined according to the display brightness difference of different pixel points of the second screen. If the display brightness of two different pixel points of the second screen is the same, then the corresponding second compensation data is the same; if the display brightness of two different pixel points of the second screen is different, then the corresponding second compensation data is different.

[0062] Step S104: display the target image.

[0063] The target image is displayed through the second screen, and the visual effect at this time is consistent with the visual effect when the image to be displayed is displayed through the first screen before the first screen is removed, and the visual effects of all pixels of the screen are consistent at this time.

[0064] It should be noted that the first compensation data and the second compensation data are both initial compensation data of the second screen, that is, compensation data when the second screen is just replaced. After using the first compensation data and the second compensation data for compensation, the compensation data is continuously adjusted based on the first compensation data and the second compensation data according to the actual display effect of the second screen and the increase in the use time of the second screen. In an example, the first compensation data can be called Deburn in compensation data, for example, the first compensation data is the initial bin file of Deburn in, and the second compensation data can be called Demura compensation data, for example, the second compensation data is the initial bin file of Demura.

[0065] In one example, Figure 2 is a schematic diagram showing a display effect according to an exemplary embodiment. Figure 2 As shown, Figure 2 Figure a in the figure represents the display effect in the related art. The first figure is the display effect of the electronic device just out of the factory. At this time, the first device uses the first screen. The second figure is the display effect of the electronic device after a period of use. At this time, the first device still uses the first screen, but due to the aging of the light-emitting device in the screen, the display brightness of the first screen decreases. The third figure is the display effect after the first screen of the electronic device is removed and replaced with the second screen. At this time, since the second screen has not aged, the display brightness of the second screen is higher than the display brightness of the first screen in the second figure when it is not removed, resulting in the display effect of the second screen in the third figure being inconsistent with the display effect of the first screen in the second figure when it is not removed, affecting the user experience; Figure 2Figure b in the figure represents the display effect in the embodiment of the present disclosure. The first figure is the display effect of the electronic device just out of the factory. At this time, the first device is using the first screen. The second figure is the display effect of the electronic device after being used for a period of time. At this time, the first device is still using the first screen, but due to the aging of the light-emitting device in the screen, the display brightness of the first screen is reduced. The third figure is the display effect after the first screen of the electronic device is removed and replaced with the second screen. At this time, the second screen is compensated by the first compensation data, so that the display brightness of the second screen is the same as the display brightness when the first screen is not removed in the second figure, that is, the display effect of replacing with the second screen in the third figure is consistent with the display effect when the first screen is not removed in the second figure.

[0066] In an exemplary embodiment of the present disclosure, first compensation data and second compensation data are obtained, and based on the first compensation data and the second compensation data, brightness parameters of the image to be displayed are adjusted to obtain a target image and display the target image. The first compensation data can be used to compensate for display abnormalities of the second screen caused by aging of the first screen, and the second compensation data can be used to compensate for display abnormalities of the second screen caused by the production process of the second screen. This method can ensure that the visual effect of the display of the first screen of the electronic device before and after screen replacement is consistent with the visual effect of the display of the second screen, and that the visual effects of the display of all pixels of the second screen are consistent, thereby avoiding the problem of inconsistent visual effects of the screen display before and after screen replacement due to not considering the aging problem of the screen before screen replacement in the related art, or the problem of inconsistent visual effects displayed in different display areas of the same screen due to not considering the screen production process, thereby improving user experience.

[0067] In an exemplary embodiment of the present disclosure, a screen display method is provided, which is applied to an electronic device. Figure 3 is a flow chart of a screen display method according to an exemplary embodiment. Figure 3 As shown, the following steps are included:

[0068] Step S301: After the first screen of the electronic device is removed and replaced with the second screen, an image to be displayed is obtained.

[0069] The specific implementation of step S301 refers to step S101 and will not be described in detail here.

[0070] Step S302, obtaining first compensation data and second compensation parameters, the first compensation data being used to compensate for display abnormality of the second screen caused by aging of the first screen, and the second compensation data being used to compensate for display abnormality of the second screen caused by production of the second screen.

[0071] The specific implementation of step S302 refers to step S102 and will not be described in detail here.

[0072] In some implementations, the first compensation data is obtained by:

[0073] Acquire third compensation data, where the third compensation data is used to compensate for display abnormality of the first screen caused by screen aging before the first screen is removed;

[0074] Based on the statistical value of the third compensation data, the first compensation data is determined.

[0075] Before the first screen was removed, it had been used for a period of time. Since the usage time of different display areas in the first screen may be different, the aging degree of different display areas is different, and the display brightness of different display areas is different, resulting in abnormal display of the first screen. In order to solve this problem, the first screen needs to be compensated to ensure that the display effect of all pixels of the first screen is consistent. The third compensation data is the data used to compensate for the display abnormality of the first screen caused by screen aging. The third compensation data corresponding to each pixel of the first screen may be the same or different, and it is determined according to the actual needs of the first screen, and the first compensation data is determined according to the statistical value of the third compensation data corresponding to all pixels of the first screen.

[0076] In one example, an average value of the third compensation data associated with all pixels of the image to be displayed is used as the first compensation data.

[0077] In another example, the maximum value of the third compensation data associated with all pixels of the image to be displayed is used as the first compensation data.

[0078] In another example, the median value of the third compensation data associated with all pixels of the image to be displayed is used as the first compensation data.

[0079] In some embodiments, the method for obtaining the first compensation data is performed by an electronic device, and before the first screen of the electronic device is removed, the third compensation data is saved in the electronic device, and after the electronic device is replaced with the second screen, the third compensation data is read, and after the first compensation data is calculated based on the third compensation data, the third compensation data is deleted, and the first compensation data is used for compensation. In some embodiments, the method for obtaining the first compensation data is performed by other electronic devices, and before the first screen of the electronic device is removed, the other electronic device reads back the third compensation data from the electronic device, and calculates the first compensation data based on the third compensation data, and after the electronic device is replaced with the second screen, the third compensation data in the electronic device is deleted, and the other electronic device imports the first compensation data into the electronic device, and the electronic device uses the first compensation data for compensation.

[0080] In some implementations, the second compensation data is obtained by:

[0081] Based on the screen identifier of the second screen, second compensation data associated with the second screen is acquired.

[0082] The screen identifier of the second screen is information that can uniquely identify the second screen, which can be called Panel ID. The second compensation data of different screens may be the same or different. Therefore, in order to ensure the display effect of the second screen, the second compensation data corresponding to the second screen is obtained according to the screen identifier of the second screen.

[0083] In one example, the second compensation data associated with the second screen is obtained by the following steps:

[0084] Sending a screen identifier of the second screen to a cloud server, wherein the cloud server stores a mapping relationship between the screen identifier of the second screen and the second compensation data;

[0085] Second compensation data sent by the cloud server is received, wherein the second compensation data is generated based on a display brightness difference between different pixel points of the second screen.

[0086] When the second screen is produced and shipped, the second screen is photographed by a preset acquisition device, and the acquired image is analyzed to determine the display brightness difference of different pixels of the second screen. According to the display brightness difference of different pixels of the second screen, the second compensation data corresponding to the second screen is generated. For example, the brightness of the pixels with higher display brightness can be lowered, and the screen identifier of the second screen and the second compensation data corresponding to the second screen are sent to the cloud server for storage. After the electronic device is replaced with the second screen, it sends the screen identifier of the second screen to the cloud server. The cloud server sends the second compensation data to the electronic device according to the mapping relationship between the stored screen identifier of the second screen and the second compensation data. The electronic device then receives the second compensation data sent by the cloud server and saves the second compensation data.

[0087] Step S303: determining screen calibration data based on the first compensation data, where the screen calibration data is used to calibrate the chromaticity of the second screen.

[0088] Since the screen calibration data will be different when the first compensation data is different, the screen calibration data is generated according to the first compensation data. The screen calibration data is used to calibrate the chromaticity of the second screen, and the calibrated chromaticity is the preset chromaticity. Based on the first compensation data, the screen calibration data is generated so that the calibrated chromaticity is adjusted to the preset chromaticity.

[0089] Step S304: adjusting the chromaticity parameters of the image to be displayed based on the screen calibration data to obtain a calibrated image.

[0090] The chromaticity parameter represents the parameter that affects the chromaticity of each pixel of the image to be displayed. For example, the chromaticity parameter is the chromaticity value of the point corresponding to the chromaticity coordinate of each pixel in the chromaticity diagram. Based on the screen calibration data, the chromaticity parameter of the image to be displayed is adjusted so that the chromaticity of the calibrated image is the preset chromaticity.

[0091] Step S305 , adjusting the brightness parameters of the calibrated image to be displayed based on the first compensation data and the second compensation data to obtain a target image.

[0092] After acquiring the calibrated image to be displayed, the brightness parameter of the calibrated image to be displayed is adjusted by using the first compensation data and the second compensation data to obtain a target image.

[0093] Step S306: display the target image.

[0094] In some embodiments, the first chip adjusts the brightness parameters of the image to be displayed based on the first compensation data to obtain an intermediate image, the intermediate image is sent to the second chip through the first chip, the second chip adjusts the brightness parameters of the intermediate image based on the second compensation data to obtain a target image, and the target image is displayed through the second chip, wherein the storage capacity of the second chip is smaller than the storage capacity of the first chip.

[0095] In some embodiments, the first chip adjusts the brightness parameters of the image to be displayed based on the first compensation data and the second compensation data to obtain a target image, sends the target image to the second chip through the first chip, and displays the target image through the second chip, wherein the storage capacity of the second chip is smaller than the storage capacity of the first chip.

[0096] The first chip is an application chip (Application Processor Integrated Circuit, APIC), which can also be called an application data processor (Application Processor Data Processing Unit, AP DPU), and the second chip is a display driver chip (Display Driver Integrated Circuit, DDIC). The storage capacity of the second chip is smaller than the storage capacity of the first chip. When the second compensation data is stored in the first chip, more compensation values ​​can be stored, which makes it more flexible when compensating the second screen, making the compensation effect of the second screen smoother and optimizing the display effect of the second screen.

[0097] In one example, the screen display method is applied to an electronic device, the electronic device includes an AP DPU and a DDIC, Figure 4 is a flow chart of a screen display method according to an exemplary embodiment. Figure 4 As shown, the AP DPU includes a DSPP module and a Deburn in module, and the DDIC includes a Demura module. The image to be processed is input into the DSPP module, and the DSPP module calibrates the chromaticity parameters of the image to be processed according to the screen calibration data, and outputs the calibrated image to be processed; the calibrated image to be processed is input into the Deburn in module, and the Deburn in module adjusts the brightness parameters of the calibrated image to be processed according to the first compensation data, and outputs an intermediate image; the intermediate image is sent to the Demura module of the DDIC, and the Demura module adjusts the brightness parameters of the intermediate image according to the second compensation data, and outputs the target image; and the target image is displayed through the DDIC.

[0098] In another example, the screen display method is applied to an electronic device, the electronic device includes an AP DPU and a DDIC, Figure 5 is a flow chart of a screen display method according to an exemplary embodiment. Figure 5 As shown, the AP DPU includes a DSPP module, a Deburn in module and a Demura module. The image to be processed is input into the DSPP module, and the DSPP module calibrates the chromaticity parameters of the image to be processed according to the screen calibration data, and outputs the calibrated image to be processed; the calibrated image to be processed is input into the Deburn in module, and the Deburn in module adjusts the brightness parameters of the calibrated image to be processed according to the first compensation data, and outputs an intermediate image; the intermediate image is input into the Demura module, and the Demura module adjusts the brightness parameters of the intermediate image according to the second compensation data, and outputs the target image; and the target image is displayed through the DDIC.
