[0042] The technical solutions in the embodiments of the present application will be described clearly below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art belong to the scope of protection of the present application.

[0043] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally a class and do not limit the number of objects, for example, the first object can be one or more. In addition, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / ", generally indicates that the objects before and after are in a "or" relationship.

[0044] The image processing method provided by the embodiments of the present application will be described in detail below in combination with the drawings, specific embodiments and application scenarios.

[0045] As shown in FIG. 1, the present application provides an image processing method applied to a display driving chip, the method comprising:

[0046] Step 101: performing light-emitting life attenuation DBI compensation processing on first image data sent by an application processor to obtain compensated first image data, wherein the first image data comprises first image display parameters.

[0047] Optionally, the first image display parameters comprise color, number, brightness, gray scale and / or resolution of pixels, etc.

[0048] Here, the display driving chip can perform DBI compensation processing on the first image data based on the DBI algorithm in the related art.

[0049] Step 102: updating and storing usage information of a display screen according to the compensated first image data, wherein the usage information of the display screen comprises display duration of the display screen in a target display scenario, and the target display scenario is determined according to the first image display parameters.

[0050] For example, the above-mentioned usage information of the display screen is the duration of displaying an image corresponding to the gray scale and brightness of the first image display parameters based on the temperature, humidity and other conditions of the environment where the display screen is located.

[0051] Optionally, the target display scenario can be determined based on the temperature of the display screen, in addition to the first image display parameter. That is, the target display scenario is determined by one or more of the color, number, brightness, gray scale, resolution of the pixels, and / or the temperature of the display screen. The parameter used to determine the display scenario can be described as a display screen aging factor. That is, the display screen aging factor can include the parameter determined based on the first image display parameter, and the display screen aging factor can also include other parameters that can describe the usage state of the display screen, which is not limited in the embodiments of the present application.

[0052] The display driving chip determines the usage time length in different display scenarios based on the display parameters of the compensated different image data and stores the same.

[0053] Since the image data compensated by the display driving chip is directly transmitted to the display screen, the DBI compensation will not be changed by other display algorithms inside the driving chip, that is, the image data compensated by DBI will not be changed again. Therefore, DBI compensation based on the image data compensated by the driving chip can effectively ensure the accuracy of the statistical usage information of the display screen.

[0054] Step 103: Every interval of the first time length, the stored usage information of the display screen is transferred to the remote memory outside the display screen module.

[0055] Optionally, the remote memory outside the display screen module includes at least one of the memory of the application processor and the memory of the mainboard.

[0056] The first time length can be pre-agreed or pre-set, and the first time length can also be determined according to the transfer operation input by the user, for example, in the case of receiving the transfer operation of the user, the stored usage information of the display screen is transferred to the memory of the application processor.

[0057] Optionally, if the transfer of the usage information of the display screen is interrupted due to objective reasons such as power failure or active reasons such as user active operation, the transfer of the usage information of the display screen is performed again after the electronic device is restarted.

[0058] By timely transferring the stored usage information of the display screen to the remote memory outside the display screen module, sufficient storage space can be ensured for the display driving chip to store the usage information of the display screen when the DBI algorithm is executed, so that the display driving chip can continuously perform DBI compensation processing on the image data.

[0059] Step 104: obtaining the display screen state information sent by the application processor, the display screen state information being obtained based on the usage information of the display screen, and the display screen state information being used to indicate the aging degree of the display screen. Optionally, after the application processor obtains the usage information of the display screen from the remote memory other than the display screen module, the application processor can convert the usage information into the display screen state information based on a preset model. For example, the parameters corresponding to the target display scene and the usage time are input into the preset model, and the display screen state information output by the model is obtained. The preset model can be obtained based on the training of the historical usage information of the display screen and the display screen state information. The preset model is a model used to represent the association between the usage information of the display screen and the display screen state information.

[0060] Optionally, after the application processor obtains the usage information of the display screen, the application processor can obtain the display screen state information based on the cumulative or statistical algorithm.

[0061] As an optional implementation manner, the aging degree of the display screen can be represented by the current value.

[0062] Step 105: performing DBI compensation processing on the second image data sent by the application processor according to the display screen state information, and outputting the compensated second image data.

[0063] The DBI compensation processing in the embodiments of the present application can include maintaining the brightness of the display screen at the initial brightness, which can be understood as the display brightness when the display screen is used for the first time or the display brightness when the display screen is used last time; or unifying the brightness of each pixel in the display screen to the same brightness, such as brightening the brightness of part of the pixels in the display screen or reducing the brightness of part of the pixels.

[0064] Through the DBI compensation processing, the related parameters (such as brightness and / or color) of each pixel position in the display screen are compensated to the target level, so as to avoid the problems such as screen burn-in or display color deviation, and the target level can be determined based on the initial brightness of the display screen.

[0065] Optionally, the longer the display screen is used, the more serious the aging of the display screen is, and the image data at the position with serious aging can be compensated by DBI compensation processing. The gray scale range that can be compensated can be calculated by a data mapping algorithm. For example, taking 8-bit color depth (i.e. 0-255 gray scale) as an example, the algorithm can first compress and map 0-255 gray scale to 0-200 gray scale, so the gray scale between 201-255 can be used for DBI gray scale compensation, and the compensated data is output to the display panel. For another example, a pixel position of the display screen originally displays 220 gray scale, which is mapped to 192 gray scale by the mapping algorithm, and according to the display screen state information, it is known that the aging of the pixel position is serious, so the 192 gray scale is modified to 255 gray scale, so as to reduce the influence of the aging of the display screen on the display effect.

[0066] Optionally, in the compensation scheme in the embodiment of the application, the application processor (AP) outputs data with 8-bit or 10-bit bit depth, the DDIC receives the data and processes it to 12-bit bit depth for DBI compensation processing, and finally outputs it through Gamma voltage. In the compensation scheme of AP DBI, the compensation is 8-bit DBI compensation, which can only compensate within 0-255 gray scale, and the compensated data is transmitted after compression. The 12-bit compensation scheme in the embodiment of the application has higher compensation accuracy, and can output gray scale values above 255 gray scale to the display panel after DBI compensation.

[0067] In the embodiment of the present application, based on the transmission speed of the communication protocol, the image data transmitted by the AP to the DDIC is 10-bit image data. After the DDIC receives the 10-bit image data transmitted by the AP, since display effect processing needs to be performed, the 10-bit image data needs to be converted into 12-bit image data through a dithering algorithm, and DBI compensation is performed based on the 12-bit image data, so that the DDIC can achieve a compensation accuracy of up to 12 bits. In the embodiment of the present application, the display driving chip performs DBI compensation processing on the first image data sent by the application processor, and updates and stores the display time of the display screen in the target display scene according to the compensated first image data; the display driving chip stores the stored information in the remote memory outside the display screen module every first time interval, and obtains the display screen state information returned by the application processor for indicating the aging degree of the display screen, and performs DBI compensation processing on the second image data sent by the application processor based on the aging degree of the display screen. In this scheme, by periodically storing the use information of the display screen in the remote memory outside the display screen module, the display driving chip can have sufficient storage space to store the use information of the display screen, so that the display driving chip can continuously perform DBI compensation processing on the image data.

[0068] Optionally, after the display screen state information sent by the application processor is obtained, the method further includes:

[0069] obtaining a target instruction sent by the application processor, the target instruction being used to instruct to clear the use information of the display screen stored by the display driving chip;

[0070] clearing the use information of the display screen stored by the display driving chip according to the target instruction, and updating and storing the use information of the display screen according to the image data compensated by the display driving chip again.

[0071] In the embodiment of the present application, after the application processor obtains the use information of the display screen, the application processor sends a target instruction to the display driving chip, so that the display driving chip obtains that the application processor has obtained the use information of the display screen, and clears the stored use information of the display screen in time, reserving storage space for storing the use information of the display screen subsequently.

[0072] Optionally, the updating and storing of the use information of the display screen include:

[0073] storing the updated use information of the display screen to the static random access memory (SRAM) of the display driving chip;

[0074] The use information of the display screen stored in the static random access memory is transferred to the memory chip of the display screen module every second time length.

[0075] Optionally, the memory chip of the display screen module is a memory of the display screen module.

[0076] Optionally, the memory of the display screen module includes a memory chip in the display screen module, which can also be described as a flash memory chip (Flash IC).

[0077] In the embodiments of the present application, the use information of the display screen obtained by statistics is temporarily stored in the SRAM, and the use information of the display screen stored in the SRAM is transferred to the memory of the display screen module every second time length, and then the use information of the display screen stored in the memory of the display screen module is transferred to the remote memory outside the display screen module, such as the memory of the application processor, so as to avoid the phenomenon of insufficient memory in the process of statistics of the use information of the display screen.

[0078] Optionally, the use information of the display screen stored is transferred to the remote memory outside the display screen module every first time length, including:

[0079] The use information of the display screen stored is transferred to the remote memory outside the display screen module every first time length in a target time window.

[0080] The target time window is a time period in which the application processor does not send data to the display driving chip.

[0081] As shown in FIG. 2, the vertical blanking period (VBP) refers to the blank time between the upper and lower two image frames on the screen in the display data transmission, which is used for resetting the scanning or performing other necessary operations. The vertical front porch (VFP) refers to the upper blank time of each row of image in the display data transmission, which is used for allowing the screen electron beam to start scanning again and preparing to display the image data of the next row. The above-mentioned target time window is the time period corresponding to the VBP.

[0082] In the embodiments of the present application, the use information of the display screen is counted at the output end of the DDIC, and then temporarily stored in the memory of the display screen module. The use information of the display screen accumulated in the memory of the display screen module is read back by the application program from the memory of the display screen module at regular intervals, and the use information read back is uploaded to the remote memory outside the display screen module in the time period in which the application processor does not send data to the display driving chip.

[0083] Here, by transmitting the use information of the display screen in the time period when the application processor does not transmit data to the display driving chip, interference of signal transmission can be effectively avoided, and normal use of the application processor to transmit data to the display driving chip will not be affected.

[0084] Optionally, the first time length is a time length for transmitting M image frames, and the second time length is a time length for transmitting N image frames, where M and N are integers, and M is greater than N.

[0085] For example, the first time length is a time length for transmitting 100 image frames, and the second time length is a time length for transmitting 50 image frames. The use information of the display screen is temporarily stored in the storage chip of the display screen module every 50 image frames, and the use information of the display screen accumulated in the storage chip of the display screen module is transmitted to the memory of the application processor every 100 image frames. Here, the first time length and the second time length are set with the transmission time corresponding to the image frame as the granularity, so that the first time length and the second time length have a smaller interval time granularity, that is, the subsequent DDIC compensates the display effect of the display screen based on the use information in a shorter time, so that the DBI compensation of the DDIC has a more accurate compensation effect. In addition, by setting the first time length to be greater than the second time length, the display driving chip can have sufficient storage space to store the use information of the display screen, and frequent transmission of data to the application processor can be avoided, and the power consumption of data transmission can be reduced.

[0086] In the above scheme of the embodiment of the application, as shown in FIG. 3, the accumulated use information of the display screen is first temporarily stored in the SRAM of the DBI by the accumulation module of the DDIC, and then written into the memory of the display screen module, read by the AP at regular intervals, and further migrated to the remote memory outside the display screen module. The use information of the display screen in the remote memory outside the display screen module is converted in format by the decoder to obtain display screen state information, which can be represented by a current parameter, and the display screen state information is transmitted to the DDIC. The DBI algorithm in the DDIC compensates the aging of the display screen based on the above display screen state information at a bit depth of 10+2=12.

[0087] The above image processing method will be described in detail in combination with specific embodiments.

[0088] In the embodiment of the present application, as shown in FIG. 4, the SRAM of the DDIC is configured for display uneven compensation (De-Mura, DMR) and DBI, and the accumulation module temporarily stores the accumulated display screen usage information in the SRAM of the DBI every 30 minutes, and further stores in the memory of the display screen module. After the interval time reaches the user-set 30 days (30*24h=720h), the DDIC first transfers the accumulated information temporarily stored in the memory of the display screen module to the SRAM of the DDIC through the serial peripheral interface (Serial Peripheral Interface, SPI) protocol, and the AP further migrates the accumulated information transferred to the SRAM to the memory of the motherboard through the mobile industry processor interface (Mobile Industry Processor Interface, MIPI) protocol. That is, the migration process of the accumulated information is: the memory of the display screen module→SRAM→the memory of the motherboard.

[0089] After the memory of the motherboard correctly acquires the usage information of the display screen, the AP issues a target instruction to the DDIC, and the DDIC clears the usage information stored in the memory of the display screen module, and marks a new accumulation starting point in the memory of the display screen module, and starts the next round of usage information accumulation. In the data transfer process, if an abnormal power failure or other sudden situation interruption occurs, the data migration can be performed again at the next restart.

[0090] The usage information of the display screen in the memory of the motherboard is converted in format by the decoder to obtain display screen state information, which can be represented by a current parameter, and the display screen state information is transmitted to the DDIC, and the DBI algorithm in the DDIC compensates the aging effect of the display screen based on the above display screen state information at 10+2=12bit depth.

[0091] In the embodiment, the usage information temporarily stored in the memory of the display screen module is read back by the AP regularly every 30 days and migrated to the memory of the motherboard. In the data transfer process, the data is unidirectional transmission, and there is no signal interference problem, and the frequency of transferring data is low, which will not increase the power consumption.

[0092] In the embodiment of the present application, as shown in FIG. 5, the SRAM of the DDIC is configured for the DMR, the overdriving compensation (ODC) and the DBI, and the accumulation module temporarily stores the accumulated usage information of the display screen in the SRAM of the DBI every 50 frame image frame transmission time interval, and further writes the accumulated usage information into the Flash IC memory. After the interval time reaches the user-set 100 frame image frame transmission time, the DDIC first transfers the temporarily stored accumulated information in the memory of the display screen module to the SRAM of the DDIC through the SPI protocol, and the AP further migrates the accumulated information transferred to the SRAM to the memory of the mainboard through the MIPI protocol. That is, the migration process of the accumulated information is: the memory of the display screen module→the SRAM→the memory of the mainboard.

[0093] After the memory of the mainboard correctly acquires the usage information of the display screen, the AP issues a target instruction to the DDIC, the DDIC clears the usage information stored in the memory of the display screen module, and marks a new accumulation starting point in the memory of the display screen module, and starts the next round of usage information accumulation. In the data transfer process, if an abnormal power failure or other sudden situation interruption occurs, the data migration can be performed again at the next restart.

[0094] The usage information of the display screen in the memory of the mainboard is converted in format by the decoder to obtain display screen state information, which can be represented by a current parameter, and the display screen state information is transmitted to the DDIC, and the DBI algorithm in the DDIC compensates the aging of the display screen based on the above display screen state information at 10+2=12 bit depth.

[0095] In the embodiment, the first time length and the second time length have a small interval time granularity, that is, the subsequent DDIC performs DBI compensation on the display effect of the usage information in a short time on the display screen, so that the DBI compensation of the DDIC can have a more accurate compensation effect.

[0096] As shown in FIG. 6, the embodiment of the present application also provides an image processing method applied to an application processor, and the method comprises:

[0097] Step 601: acquiring the usage information of the display screen transferred by the display driving chip every interval of the first time length, wherein the usage information of the display screen comprises a display time length of the display screen in a target display scene, and the target display scene is determined according to a first image display parameter in compensated first image data.

[0098] Optionally, the first image display parameter includes color, number, brightness, gray scale, resolution and / or the like of pixels.

[0099] For example, the usage information of the display screen is a time length during which the display screen displays an image in the gray scale and brightness corresponding to the first image display parameter based on temperature, humidity and / or the like of an environment in which the display screen is located.

[0100] Optionally, the target display scenario is determined based on the first image display parameter and the temperature of the display screen. That is, the target display scenario is determined by color, number, brightness, gray scale, resolution of pixels and / or the temperature of the display screen. The parameter used to determine the display scenario can be described as a display screen aging factor. Of course, the display screen aging factor can also include other parameters, which are not limited in the embodiments of the present application.

[0101] Step 602: obtaining display screen state information according to the usage information of the display screen, the display screen state information being used to indicate an aging degree of the display screen.

[0102] Optionally, after the application processor obtains the usage information of the display screen, the usage information can be converted into the display screen state information based on a preset model. For example, the parameter corresponding to the target display scenario and the time length of use are input into the preset model, and the display screen state information output by the model is obtained.

[0103] As an optional implementation manner, the aging degree of the display screen can be represented by a current value.

[0104] Step 603: sending the display screen state information to the display driving chip.

[0105] In the embodiments of the present application, the application processor obtains the usage information of the display screen stored by the display driving chip every first time length; obtains the display screen state information according to the usage information of the display screen, the display screen state information being used to indicate the aging degree of the display screen; and sends the display screen state information to the display driving chip, so that the display driving chip can perform DBI compensation based on the display screen state information. The application processor obtaining the usage information of the display screen stored by the display driving chip every first time length can ensure that the display driving chip has sufficient storage space to store the usage information of the display screen, so that the display driving chip can continuously perform DBI compensation processing on the image data.

[0106] Optionally, obtaining the display screen state information according to the usage information of the display screen includes:

[0107] The usage information of the display screen is format-converted to obtain display screen usage information in a target format that can be recognized by both the display driving chip and the application processor.

[0108] According to the display screen usage information in the target format, display screen state information is obtained, the display screen state information including a target current value indicating the aging degree of the display screen, wherein the display time length of the display screen under a target display scenario is positively correlated with the aging degree of the display screen.

[0109] In the embodiments of the present application, the application processor converts the usage information of the display screen through a translator into a format that can be recognized by both the display driving chip and the application processor, and obtains a target current value indicating the aging degree of the display screen based on the converted usage information, so as to enable the DDIC to perform DBI compensation processing based on the target current value.

[0110] Optionally, the display driving chip stores the usage information of the display screen every first time interval, and the method further comprises:
