[0021] In order to enable those skilled in the art to better understand the technical solutions in the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

It should also be understood that the term "and / or" used herein refers to and includes any or all possible combinations of one or more associated listed items.

[0023] It should be understood that although the terms first, second, third, etc. may be used in the present application to describe various information, these information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present application, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Depending on the context, the word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining".

[0024] The technical solutions in the embodiments of the present application are clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application. In the absence of conflict, the following embodiments and their technical features can be combined with each other.

[0025] The current active-matrix organic light-emitting diode (AMOLED) panels mainly include TFT devices and OLED devices. Thin-film transistors (TFT) have a hysteresis effect, that is, after a signal is input on the display, the response time of the display is longer than the change time of the signal, that is, the update speed of the display is slower than the change speed of the signal. When the organic light-emitting diode (OLED) is used as a pixel to display dynamic images, the mismatch between the response speed of the luminescent material and the refresh rate leads to the problem of ghosting when the AMOLED panel is displayed. In order to reduce the impact of these aspects, multiple scan pulses are currently used on the screen, such as the 3-scan pulse method or an integrated overdriver algorithm is developed in the display driver chip to improve the panel response time and improve the display ghosting problem. Since the frequency of the periodic charge / discharge state of the multiple scan pulse method is several times that of the conventional solution, the dynamic power consumption of the module, especially the driver chip, will be increased in real time during the display process. In addition, the current overdriver algorithm development (whether in DSI Command Mode or DSI Video Mode) has certain unnecessary power consumption losses because it must give compensation values ​​corresponding to display data in any application scenario. Therefore, the present application proposes a display data compensation method, a display unit, a controller and a computer storage medium to at least partially solve the above problems.

[0026] Figure 1 1 is a flowchart of the steps of a display data compensation method according to an embodiment of the present application. Figure 1 As shown, the display data compensation method includes the following steps:

[0027] Step 101: Obtain the data to be displayed of the current frame.

[0028] Step 102, compare the data to be displayed with the display data of the previous frame to obtain a comparison result, and determine whether the data to be displayed is the same as the display data of the previous frame according to the comparison result. If so, execute step 103, if not, execute step 104.

[0029] Step 103: Start the display compensation module to compensate the data to be displayed, obtain the compensated display data, and end the current process so that the display module performs display according to the compensated display data.

[0030] Step 104: close the display compensation module so that the display module performs display according to the data to be displayed.

[0031] In the display scenario, the data to be displayed can be obtained by drawing the image to be displayed by the application processor (AP). After the AP generates the data to be displayed, it will be sent to the display module for display. In this process, in order to solve the problem of ghosting, the data to be displayed will be compensated by the display compensation module, so that the display module has a better display effect when displaying according to the compensated data. In order to reduce the power consumption occupied by the display compensation module, before the display compensation module compensates the data to be displayed, the data to be displayed of the current frame can be obtained first, and the data to be displayed of the current frame can be compared with the display data of the previous frame to obtain a comparison result. If the comparison result indicates that the data to be displayed of the current frame has changed relative to the display data of the previous frame, the display compensation module is started to compensate for the data to be displayed. If the comparison result indicates that the data to be displayed of the current frame has not changed relative to the display data of the previous frame, the display compensation module is turned off to reduce the power consumption of the display compensation module.

[0032] Specifically, the process of obtaining the data to be displayed of the current frame may further include: obtaining the first row of display data included in the data to be displayed of the current frame in sequence row by row. Figure 2 As shown, the process of comparing the data to be displayed with the display data of the previous frame and obtaining the comparison result may also include the following steps:

[0033] Step 1021 : Compare the acquired first row of display data with the second row of display data corresponding to the row of display data in the previous frame of display data to obtain a row display data comparison result.

[0034] Step 1022 : Obtain a comparison result based on the comparison results of multiple rows of display data corresponding to the first row of display data in the data to be displayed in the current frame.

[0035] Step 1023 , judging whether the data to be displayed is the same as the display data of the previous frame according to the comparison result, if so, executing step 103 , if not, executing step 104 .

[0036] When the AP transmits data to be displayed, the data to be displayed is usually sent row by row. Therefore, in the process of comparing the data to be displayed in the current frame with the display data of the previous frame, the first row of display data obtained is first compared with the second row of display data corresponding to the row of display data in the display data of the previous frame, and then the first row of display data obtained subsequently is compared with the second row of display data corresponding to the row of display data in the display data of the previous frame, until all the data to be displayed are compared with the display data of the previous frame. Each time the first row of display data is compared, a row display data comparison result is obtained, and based on the multiple row display data comparison results obtained during the comparison process, a comparison result of the data to be displayed and the display data of the previous frame can be obtained. By comparing the row display data, the accuracy of the comparison can be improved.

[0037] Specifically, the display data compensation process may further include: when the first row of data to be displayed is acquired, performing a cyclic redundancy check on the received first row of data to be displayed, and storing the cyclic redundancy check result in a memory.

[0038] In order to facilitate comparison, a cyclic redundancy check (CRC) can be performed on the first line of received data to be displayed. The cyclic redundancy check method can be CRC16 or CRC32. After the cyclic redundancy check is completed, the result of each cyclic redundancy check is stored in a memory. The memory can be a Line buffer unit in a display chip.

[0039] Correspondingly, the acquired first row of display data is compared with the second row of display data corresponding to the row of display data in the previous frame of display data, and the process of obtaining the row display data comparison result may also include:

[0040] The cyclic redundancy check result corresponding to the first row of display data is compared with the cyclic redundancy check result corresponding to the second row of display data to obtain a row display data comparison result.

[0041] Since, in the process of receiving the display data of the previous frame, the display data of the first number of rows included in the display data of the previous frame have been respectively subjected to cyclic redundancy check and stored, therefore, when receiving the data to be displayed of the current frame and respectively conducting cyclic redundancy check on the display data of the first number of rows included in the data to be displayed of the current frame, the cyclic redundancy check result corresponding to the first row of display data can be compared with the cyclic redundancy check result corresponding to the second row of display data to obtain the row display data comparison result. By conducting cyclic redundancy check on the display data of the first number of rows, it is possible to facilitate the comparison of display data.

[0042] It should be noted that the first number of rows can be determined based on the data transmission time length of the data to be displayed from the receiving module to the display module. The specific determination method can be: firstly, the data transmission time length of the data to be displayed from the receiving module to the display module is obtained, then the second number of rows of row display data included in the data to be displayed is determined within the data transmission time length, and finally the first number of rows is determined based on the second number of rows, so that the first number of rows is less than the second number of rows.

[0043] Since it takes a certain data transmission time for the data to be displayed to be sent from the receiving module to the display module, and the comparison between the data to be displayed of the current frame and the display data of the previous frame is completed within the data transmission time, and then the compensation of the data to be displayed is completed, there is no need to delay the display of the display module. Therefore, the data transmission time is first determined, such as 10ms, and the number of rows of data to be displayed that can be obtained within the data transmission time is further calculated to determine the second row number. Therefore, the number of rows compared with the row display data included in the data to be displayed is controlled within the second row number, so as to ensure the normal display of the display module. The second row number is usually 5 rows, and the first row number is usually set to 1-3 rows.

[0044] Specifically, if the data to be displayed is different from the display data of the previous frame, the process of starting the display compensation module to compensate the data to be displayed may also include:

[0045] If the row display data comparison result indicates that the row display data of the first row is different from the corresponding row display data in the display data of the previous frame, the display compensation module is started to compensate the row display data of the first row.

[0046] The logic timing diagram of controlling the display compensation module to compensate the display data can be as follows: Figure 3 As shown, it can be seen that the logic of starting the display compensation module can be determined according to the comparison result of the row display data. In the N+4 frame, some row display data are the same as those in the N+3 frame, and some are different. Then, the display compensation module is controlled to be turned off in the same part, and the display compensation module is started in the different part, which can further reduce power consumption.

[0047] Figure 4 is a schematic diagram of a display unit according to an embodiment of the present application. Figure 4 As shown, the display unit 400 includes: an application processor 401 and a display driver chip 402 .

[0048] The application processor 401 is used to draw the image to be displayed to obtain the data to be displayed, and send the data to be displayed to the display driver chip 402 through the display interface transmitter 4011. The display driver chip 402 includes: a display interface receiving end 4021, a controller 600, a display compensation module 4022 and a display module 4023. The display interface receiving end 4021 is used to receive the data to be displayed. The controller 600 is used to execute the method in the above embodiment to control the startup and shutdown of the display compensation module 4022. The display compensation module 4022 is used to compensate the data to be displayed at startup and obtain the compensated display data so that the display module 4023 displays according to the compensated display data.

[0049] In the display scene, the data to be displayed can be obtained by the application processor 401 (AP) drawing the image to be displayed. After the application processor 401 generates the data to be displayed, it will be sent to the display driver chip 402 for display. In this process, in order to solve the problem of smearing, the display driver chip 402 will compensate the data to be displayed through the display compensation module 4022, so that the display module 4023 has a better display effect when displaying according to the compensated data. In order to reduce the power consumption occupied by the display compensation module 4022, the controller 600 can obtain the data to be displayed of the current frame before the display compensation module 4022 compensates the data to be displayed, and compare the data to be displayed of the current frame with the display data of the previous frame to obtain the comparison result. If the comparison result indicates that the data to be displayed of the current frame has changed relative to the display data of the previous frame, the display compensation module 4022 is started to compensate for the data to be displayed. If the comparison result indicates that the data to be displayed of the current frame has not changed relative to the display data of the previous frame, the display compensation module 4022 is turned off to reduce the power consumption of the display compensation module 4022.

[0050] Figure 5 is a schematic diagram of a display unit of another embodiment of the present application, such as Figure 5 As shown, the display unit 400 may further include: a memory 4024 .

[0051] The memory 4024 is used to store the cyclic redundancy check result obtained by the controller 600 performing the cyclic redundancy check on the received row display data of the first number of rows.

[0052] When the application processor 401 transmits the data to be displayed, the data to be displayed is usually sent row by row. Therefore, when the controller 600 compares the data to be displayed of the current frame with the display data of the previous frame, the first row of display data obtained is first compared with the second row of display data corresponding to the row of display data in the display data of the previous frame, and then the first row of display data obtained subsequently is compared with the second row of display data corresponding to the row of display data in the display data of the previous frame, until all the data to be displayed are compared with the display data of the previous frame. Each time the first row of display data is compared, a row display data comparison result is obtained. According to the multiple row display data comparison results obtained during the comparison process, the comparison result of the data to be displayed and the display data of the previous frame can be obtained. By comparing the row display data, the accuracy of the comparison can be improved.

[0053] In order to facilitate comparison, the controller 600 may perform a cyclic redundancy check (CRC) on the received first line of data to be displayed, and the cyclic redundancy check method may be CRC16 or CRC32. After completing the cyclic redundancy check, the controller 600 stores the result of each cyclic redundancy check in the memory 4024. The memory 4024 may be a line buffer unit in the display chip.

[0054] In this embodiment, a controller 600 is provided, such as Figure 6 As shown, the controller 600 may include: a processor 601, a communications interface 602, a memory 603, and a communication bus 604. Among them:
