[0084] 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.

[0085] With the development of organic light-emitting diodes (OLED), OLED displays are widely used in mobile terminals for image display. However, due to the limitations of the OLED display manufacturing process, OLED displays are prone to uneven brightness (i.e., Mura). To address this problem, the DeMura data can be determined based on the DeMura technology in the related art to compensate for the Mura of the display data of the pixels in the display, that is, to remove the Mura of the OLED display.

[0086] However, since OLED displays usually emit light by directly stimulating the coating on the pixel color unit, screen burn-in may occur after long-term use. For example, if a user uses an application for a long time and there is an area in the display screen of the application that remains unchanged during the screen switching process, there is a high possibility that screen burn-in may occur in the unchanged area, that is, when other images are displayed, the area will leave a shadow-like background, resulting in a poor user experience.

[0087] To address this problem, the related art usually detects all pixels of the entire image of the OLED display screen based on the display driver chip DDIC or the application processor AP to achieve burn-in repair. However, the above-mentioned solution for detecting all pixels of the entire image of the OLED display screen requires continuous screenshots on the OLED display screen based on a preset time interval, and continuous weighted averaging of the screenshot content, which not only requires a large data storage and computing space, but also leads to increased system power consumption, which cannot meet actual application needs. Moreover, in the solution of implementing burn-in repair based on the application processor AP in the related art, since it is necessary to lower the grayscale value of the normal area (i.e., the non-burn-in area) to ensure the consistency of the display effect of the display screen, it will result in low compensation accuracy.

[0088] In view of this, the present disclosure provides the following data processing methods, devices, equipment and storage media to solve the above-mentioned deficiencies in the related art.

[0089] Figure 1 is a flow chart of a data processing method according to an exemplary embodiment; the method of this embodiment can be executed by a data processing device, and the data processing device can be configured in an electronic device, such as a server, a workstation, a personal computer, a mobile terminal (such as a mobile phone, a tablet computer, etc.), a wearable device (such as glasses, a watch, etc.), etc. Specifically, Figure 1 As shown, the method includes the following steps S101-S103:

[0090] In step S101, in response to detecting that an application interface of a target application is displayed on a display screen, display data of a target area in the application interface is counted to obtain a target statistical result.

[0091] In this embodiment, when the electronic device detects that an application interface of a target application is displayed on a display screen, it can count display data of a target area in the application interface to obtain a target statistical result.

[0092] The target area may be an area associated with display screen burn-in. For example, the target area may be an area where the target application remains unchanged during screen switching. In some embodiments, the target area may be determined based on the type of the target application.

[0093] For example, if the target application is a short video or live broadcast application, the target area may be at least one of the display areas such as "+" or "Home" in the application interface. If the target application is a shopping application, the target area may be at least one of the display areas such as "Message" or "Shopping Cart" in the application interface.

[0094] Exemplarily, counting the display data of the target area in the application interface may include counting at least one of the grayscale information of the target area, the backlight value of the current display screen, and the time, so as to obtain a target statistical result.

[0095] In some other embodiments, the above-mentioned method of counting the display data of the target area in the application interface can also refer to the following Figure 2 The illustrated embodiment will not be described in detail here.

[0096] In step S102, grayscale compensation data of the target area is determined based on the target statistical result.

[0097] In this embodiment, after the display data of the target area in the application interface is counted to obtain a target statistical result, the grayscale compensation data of the target area can be determined based on the target statistical result.

[0098] In some embodiments, the grayscale compensation data corresponding to the target statistical result may be determined based on a pre-constructed correspondence between the display data statistical result and the grayscale compensation data.

[0099] In some other embodiments, the above method of determining the grayscale compensation data of the target area based on the target statistical result can also refer to the following Figure 4A The illustrated embodiment will not be described in detail here.

[0100] In step S103 , DeMura target data is determined based on the pre-acquired DeMura raw data and the grayscale compensation data.

[0101] In this embodiment, after the grayscale compensation data of the target area is determined based on the target statistical result, the DeMura target data may be determined based on the pre-acquired DeMura original data and the grayscale compensation data.

[0102] In some embodiments, the electronic device can obtain the DeMura raw data from the storage space (e.g., screen Flash) associated with the display driver chip DDIC in response to detecting that the display screen is lit. Further, after the grayscale compensation data of the target area is determined based on the target statistical result, the DeMura target data can be determined based on the grayscale compensation data and the DeMura raw data obtained from the DDIC.

[0103] For example, the first compensation data corresponding to the target area in the DeMura original data can be superimposed with the grayscale compensation data, and the second compensation data corresponding to other areas in the DeMura original data can be retained to obtain the DeMura target data. It can be understood that the other areas refer to areas other than the target area.

[0104] In other embodiments, the electronic device may also write the DeMura target data into a storage space (e.g., screen Flash) associated with the display driver chip DDIC in response to obtaining the DeMura target data. Then, when it is subsequently detected that the display screen meets the set conditions, the DeMura target data may be obtained from the storage space to perform Mura compensation on the display data of the pixels in the display screen based on the DeMura target data.

[0105] It is worth noting that the above-mentioned setting conditions can be set based on the needs of the actual application scenario, and this embodiment does not limit this. For example, the electronic device can respond to detecting that the display screen is lit up next time (that is, the display screen is lit up again after being turned off), determine that the display screen meets the above-mentioned setting conditions, and then obtain the previously stored DeMura target data from the Flash for Mura compensation.

[0106] In some embodiments, the above steps S101-S103 can be implemented in the application processor AP to reduce the RAM occupation on the DDIC, and the subsequent Mura compensation based on the DeMura target data can be implemented on the DDIC to avoid the problem of low compensation accuracy caused by the solution of implementing burn-in repair based on the application processor AP, which can improve the compensation accuracy of the entire machine.

[0107] As can be seen from the above description, the method of this embodiment counts the display data of the target area in the application interface in response to detecting the application interface of the target application displayed on the display screen, obtains the target statistical result, and determines the grayscale compensation data of the target area based on the target statistical result, and then determines the DeMura target data based on the pre-acquired DeMura original data and the grayscale compensation data. Since the target area is an area associated with the display screen burn-in, it is easy to cause burn-in in the target area, and then by counting the display data of the target area in the application interface, and determining the grayscale compensation data of the target area based on the obtained target statistical result, and then determining the DeMura target data, it is possible to implement subsequent burn-in repair based on the data, and compared with the solution of storing and calculating all pixels of the entire image in the related art, it can save data storage and calculation space, and can reduce system power consumption, and implement burn-in repair by performing Mura compensation based on DeMura target data, which can be implemented in the display driver chip DDIC, and thus can avoid the problem of low compensation accuracy caused by the solution of implementing burn-in repair based on the application processor AP in the related art.

[0108] Figure 2 It is a flowchart showing how to count the display data of the target area in the application interface according to an exemplary embodiment of the present disclosure; based on the above embodiment, this embodiment uses how to count the display data of the target area in the application interface as an example to illustrate.

[0109] like Figure 2 As shown, the counting of display data of the target area in the application interface in the above step S101 may include the following steps S201-S203:

[0110] In step S201, in response to detecting that the screen brightness of the display screen changes, display information of the target area in the application interface of the target application currently displayed is recorded.

[0111] In this embodiment, the electronic device may record the display information of the target area in the application interface of the target application currently displayed when detecting that the screen brightness of the display screen changes.

[0112] In some embodiments, in response to detecting that the target application is started, the electronic device may record initial display information of the initial application interface of the target application currently displayed, and use the initial display information as the display information recorded for the first time.

[0113] That is to say, the display information recorded by the electronic device for the first time is the display information of the first application interface displayed after the target application is started, and the display information recorded each time thereafter may be the display information when the backlight brightness of the display changes.

[0114] In step S202, display data within at least one period is determined based on the display information. Display data within at least one period is determined based on the display information.

[0115] In this embodiment, in response to detecting a change in the screen brightness of the display screen, after recording the display information of the target area in the application interface of the target application currently displayed, the display data within at least one period can be determined based on the display information.

[0116] In some embodiments, the display data in each cycle can be determined based on the display information recorded twice adjacently. For example, assuming that N display information is currently recorded, namely, the first display information, the second display information, ..., the Nth display information, then the display data of the first cycle can be determined based on the first display information and the second display information, the display data of the second cycle can be determined based on the second display information and the third display information, ..., the display data of the N-1th cycle can be determined based on the N-1th display data and the Nth display data. Wherein, N is a positive integer greater than or equal to 2.

[0117] In some other embodiments, the above-mentioned method of determining the display data within at least one period based on the display information can also refer to the following Figure 3 The illustrated embodiment will not be described in detail here.

[0118] In step S203, the target statistical result is determined based on the display data in the at least one cycle.

[0119] In this embodiment, after display data within at least one cycle is determined based on the display information, the target statistical result may be determined based on the display data within the at least one cycle.

[0120] For example, the target statistical result may be obtained by performing a weighted sum operation on the display data in the at least one cycle. It is understandable that when the weights corresponding to the display data in each cycle are equal, the target statistical result may be the average value of the display data in the at least one cycle.

[0121] As can be seen from the above description, this embodiment records the display information of the target area in the application interface of the target application currently displayed in response to detecting a change in the screen brightness of the display screen, and determines the display data within at least one period based on the display information, and determines the target statistical result based on the display data within the at least one period, so as to accurately count the display data of the target area in the application interface. Moreover, since the display information of the target area in the application interface of the target application currently displayed is recorded when a change in the screen brightness of the display screen is detected, compared with the solution of continuously taking screenshots on the OLED display screen based on a preset time interval in the related art, the amount of data that needs to be counted can be greatly reduced, thereby further saving data storage and computing space.

[0122] Figure 3 It is a flowchart showing how to determine display data within at least one cycle based on the display information according to an exemplary embodiment of the present disclosure; this embodiment, based on the above embodiment, uses an example of how to determine display data within at least one cycle based on the display information to exemplify.

[0123] In this embodiment, the display information of two adjacent records may include the first grayscale information of the target area in the first application interface of the previous record, the first backlight value and the first display time of the display screen, and the current display time of the second application interface of the current record.

[0124] That is to say, each time the display information is recorded, the current grayscale information of the target area in the current application interface, the current backlight value of the display screen, and the current display time may be used. When the display data of the current cycle is subsequently determined based on the currently recorded display information and the display information recorded last time, only the first grayscale information of the target area in the first application interface recorded last time, the first backlight value of the display screen, the first display time, and the current display time may be used, without using the current grayscale information of the target area in the current application interface and the current backlight value of the display screen.

[0125] Specifically, Figure 3 As shown, the step S202 of determining the display data within at least one cycle based on the display information may include the following steps S301-S303:

[0126] In step S301, the maximum grayscale brightness of the current screen is determined based on the first backlight value and the fixed parameters of the display screen.

[0127] In this embodiment, when determining the display data of the current cycle, the current maximum grayscale brightness of the screen can be determined based on the first backlight value and the fixed parameters of the display screen, wherein the fixed parameters include the initial maximum backlight value and the initial maximum grayscale brightness.

[0128] For example, assuming that the first backlight value is DBV, the initial maximum backlight value is DBVmax, and the initial maximum grayscale brightness is Lvmax, the current maximum grayscale brightness Lv of the screen can be determined based on the following formula (3-1):

[0129] Lv=(DBV / DBVmax)*Lvmax; (3-1)

[0130] In step S302, a first grayscale brightness corresponding to the first grayscale information is determined based on the current maximum grayscale brightness of the screen and the first grayscale information.

[0131] In this embodiment, after the maximum grayscale brightness of the current screen is determined based on the first backlight value and the fixed parameters of the display screen, the first grayscale brightness corresponding to the first grayscale information can be determined based on the maximum grayscale brightness of the current screen and the first grayscale information.

[0132] For example, assuming that the first grayscale information is G, the first grayscale brightness LvG can be determined based on the following formula (3-2):

[0133] LvG=(G / 255)^2.2*Lv; (3-2)

[0134] In step S303, based on the first grayscale brightness, the first display time and the current display time, the brightness time of the first grayscale information is determined and used as display data in the current cycle.

[0135] In this embodiment, after the first grayscale brightness corresponding to the first grayscale information is determined based on the current maximum grayscale brightness of the screen and the first grayscale information, the brightness time of the first grayscale information can be determined based on the first grayscale brightness, the first display time and the current display time, and used as the display data in the current cycle.

[0136] For example, assuming that the first display time is t0 and the current display time is t1, the brightness time Lvdec_i of the first grayscale information can be determined based on the following formula (3-3) and used as the display data in the current cycle (eg, the i-th cycle):

[0137] Lvdec_i=LvG*(t1-t0); (3-3)

[0138] On this basis, the display data in each cycle can be calculated in the above manner to obtain the display data in N cycles, such as Lvdec_1, Lvdec_2, ..., Lvdec_N. Further, the target statistical result Lvdec can be determined based on the following formula (3-4):

[0139] Lvdec=(a1*Lvdec_1+a2*Lvdec_2+……+aN*Lvdec_N) / N; (3-4)

[0140] In the above formula, a1, a2, ..., aN are weights corresponding to the display data in the corresponding period.

[0141] As can be seen from the above description, this embodiment determines the maximum grayscale brightness of the current screen based on the first backlight value and the fixed parameters of the display screen, and determines the first grayscale brightness corresponding to the first grayscale information based on the maximum grayscale brightness of the current screen and the first grayscale information, and then determines the brightness time of the first grayscale information based on the first grayscale brightness, the first display time and the current display time, and uses it as the display data in the current cycle, so that the display data in the current cycle can be determined, and then the display data in at least one cycle can be determined in this way, laying a foundation for the subsequent determination of the target statistical result based on the display data in the at least one cycle, so that the grayscale compensation data of the target area can be determined based on the obtained target statistical result, and then the DeMura target data can be determined, so that the subsequent burn-in repair can be performed based on the data, saving data storage and computing space, and can reduce system power consumption and improve the compensation accuracy of the burn-in repair solution.

[0142] Figure 4A It is a flowchart showing how to determine the grayscale compensation data of the target area based on the target statistical results according to an exemplary embodiment of the present disclosure; based on the above embodiment, this embodiment uses an example of how to determine the grayscale compensation data of the target area based on the target statistical results.

[0143] like Figure 4A As shown, the above step S102 of determining the grayscale compensation data of the target area based on the target statistical result may include the following steps S401-S404:

[0144] In step S401, a target brightness decay time is determined based on the target statistical result and the initial maximum grayscale brightness of the display screen.

[0145] In this embodiment, after the display data of the target area in the application interface is counted to obtain a target statistical result, the target brightness decay time can be determined based on the target statistical result and the initial maximum grayscale brightness of the display screen.

[0146] For example, assuming that the target statistical result is Lvdec and the initial maximum grayscale brightness of the display is Lvmax, the target brightness decay time t can be determined based on the following formula (4-1):

[0147] t=Lvdec / Lvmax; (4-1)

[0148] In step S402, based on the pre-constructed correspondence between the brightness decay ratio and the brightness decay time, a target brightness decay ratio corresponding to the target brightness decay time is determined.

[0149] In this embodiment, after the target brightness decay time is determined based on the target statistical results and the initial maximum grayscale brightness of the display screen, the target brightness decay ratio corresponding to the target brightness decay time can be determined based on the pre-constructed correspondence between the brightness decay ratio and the brightness decay time.

[0150] For example, Figure 4B is a schematic diagram showing the corresponding relationship between the brightness decay ratio and the brightness decay time according to an exemplary embodiment of the present disclosure. Figure 4B As shown, the horizontal axis is the brightness decay time, in hours (h), and the vertical axis is the brightness decay ratio, in percentage (%). Furthermore, after the target brightness decay time t is determined based on the above formula (4-1), the corresponding brightness decay ratio r can be found based on the above corresponding relationship, that is, the target brightness decay time t corresponds to the vertical coordinate of the point on the curve.

[0151] In step S403, target grayscale information after grayscale compensation is determined based on the target attenuation ratio and the initial grayscale information.

[0152] In this embodiment, after determining the target brightness attenuation ratio corresponding to the target brightness attenuation time, the target grayscale information after grayscale compensation can be determined based on the target attenuation ratio and initial grayscale information. The initial grayscale information can be the grayscale information of the initial application interface of the target application.

[0153] For example, assuming that the initial grayscale information is G, the relationship between the initial grayscale G and the target grayscale information G1 can be expressed based on the following formula (4-2):

[0154] (G1 / 255)^2.2*r=(G / 255)^2.2; (4-2)

[0155] On this basis, the target grayscale information G1 can be determined based on the following formula (4-3):

[0156] G1=G*(1 / r)^(1 / 2.2); (4-3)

[0157] In step S404, the grayscale compensation data is determined based on the target grayscale information and the initial grayscale information.

[0158] In this embodiment, after the target grayscale information after grayscale compensation is determined based on the target attenuation ratio and the initial grayscale information, the grayscale compensation data may be determined based on the difference between the target grayscale information and the initial grayscale information.

[0159] That is to say, the grayscale compensation data can be determined based on the following formula (4-4):

[0160] Grayscale compensation data = G1-G; (4-4)

[0161] On this basis, the above-mentioned grayscale compensation data "G1-G" can be superimposed with the DeMura original data read from the storage space associated with DDIC (such as screen Flash) to obtain the final compensation data, that is, the DeMura target data, and written into the above-mentioned storage space to achieve subsequent compensation of the display data of the pixels in the display screen, thereby reducing the risk of screen burn-in of the display screen.

[0162] As can be seen from the above description, this embodiment determines the target brightness decay time based on the target statistical result and the initial maximum grayscale brightness of the display screen, and determines the target brightness decay ratio corresponding to the target brightness decay time based on the pre-established correspondence between the brightness decay ratio and the brightness decay time, and then determines the target grayscale information after grayscale compensation based on the target decay ratio and the initial grayscale information, and then determines the grayscale compensation data based on the target grayscale information and the initial grayscale information, so that the grayscale compensation data of the target area can be determined based on the target statistical result, and then the DeMura target data can be subsequently determined based on the grayscale compensation data, so that the subsequent burn-in repair based on the data can be realized, and compared with the solution of storing and calculating all pixels of the entire image in the related art, data storage and calculation space can be saved, and system power consumption can be reduced, and the burn-in repair is realized by performing Mura compensation based on the DeMura target data, which can be realized in the display driver chip DDIC, thereby avoiding the problem of low compensation accuracy caused by the solution of implementing burn-in repair based on the application processor AP in the related art.

[0163] Figure 5is a block diagram of a data processing device according to an exemplary embodiment of the present disclosure; the device of this embodiment can be configured in an electronic device with a display screen, such as a server, a workstation, a personal computer, a mobile terminal (such as a mobile phone, a tablet computer, etc.), a wearable device (such as glasses, a watch, etc.), etc. Specifically, Figure 5 As shown, the device may include: a display data statistics module 110, a compensation data determination module 120 and a target data determination module 130, wherein:

[0166] The target data determination module 130 is configured to determine DeMura target data based on the pre-acquired DeMura original data and the grayscale compensation data.

Since the target area is an area associated with the display screen burn-in, it is easy to cause burn-in in the target area, and then by counting the display data of the target area in the application interface, and determining the grayscale compensation data of the target area based on the obtained target statistical result, and then determining the DeMura target data, it is possible to implement subsequent burn-in repair based on the data, and compared with the solution of storing and calculating all pixels of the entire image in the related art, it can save data storage and calculation space, and can reduce system power consumption, and implement burn-in repair by performing Mura compensation based on DeMura target data, which can be implemented in the display driver chip DDIC, and thus can avoid the problem of low compensation accuracy caused by the solution of implementing burn-in repair based on the application processor AP in the related art.
