The AOD mode is mainly used in display screens such as organic light-emitting diodes (OLED) that can control each pixel individually. This screen can only light up some pixels in the off state. For example, when the display content is only a digital clock or a simple notification, only a few required pixels can be activated in AOD mode to achieve the purpose of reducing power consumption. This design not only allows users to view key information without waking up the screen, but also extends the battery life of the device, and is therefore widely welcomed.

[0063] In recent years, with the development of display technology and the continuous improvement of user needs, the application demand of Always On Display (AOD) mode has also increased. The AOD mode is mainly used in display screens such as organic light-emitting diodes (OLED) that can control each pixel individually. This screen can only light up some pixels in the off state. For example, when the display content is only a digital clock or a simple notification, only a few required pixels can be activated in AOD mode to achieve the purpose of reducing power consumption. This design not only allows users to view key information without waking up the screen, but also extends the battery life of the device, and is therefore widely welcomed.

[0064] At present, many display driver ICs (DDICs) have the design function of AOD mode. However, with the advancement of technology and the increase of user demand, the application requirements of display accuracy and diversity in AOD mode are gradually increasing. The existing display control scheme in AOD mode has become insufficient in some scenarios and cannot meet the display flexibility requirements, becoming a technical bottleneck.

[0065] In view of this, the present disclosure provides a method, apparatus, display device and electronic device for controlling screen-off display. The method for controlling screen-off display of the present disclosure obtains a preset gamma curve for other display modes in response to the screen-off display mode being turned on and the screen-off display function being turned on, replaces the original gamma curve for the screen-off display mode with the preset gamma curve as the target gamma curve, processes the image to be displayed based on the target gamma curve, obtains the processed image to be displayed and displays it in the screen-off display mode, and can allocate the gamma curve in other modes with better display effects to the screen-off display mode, so that the screen-off display mode can have higher display accuracy and achieve better display effects, so as to meet diverse application requirements, be more flexible and improve user experience.

[0066] Figure 1 A schematic diagram showing an application scenario according to an embodiment of the present disclosure is shown. Figure 1As shown, the off-screen display control system of the embodiment of the present disclosure can be deployed in a display device, and the display device can also include a display screen. In the application scenario of the present disclosure, the display screen can be an OLED display screen, etc. When the display device is in the off-screen state, the off-screen display mode (i.e., AOD mode) can be turned on to control the screen to display partial information such as clock, notification, weather information, etc. The off-screen display control system of the present disclosure can replace the gamma curve of the original AOD mode with the gamma curve used for other display modes when the AOD mode is turned on and the off-screen display function (hereinafter referred to as the full-aod function) is turned on, and the image to be displayed is processed based on these gamma curves used for other display modes to obtain the processed image to be displayed, so as to be displayed on the display screen.

[0067] Figure 2 FIG. 1 is a flowchart showing a method for controlling a screen-off display according to an embodiment of the present disclosure. The method can be used for a display device such as Figure 2 As shown, the method may include:

[0068] Step S201, in response to the screen-off display mode being turned on and the screen-off display function being turned on, obtaining a preset gamma curve for other display modes.

[0069] The AOD mode is the screen-off display mode. In AOD mode, the display device is in the screen-off state, but the display can still display some information, such as clock, notifications, weather information, etc., without waking up the entire display.

[0070] The screen-off display function is the full-aod function mentioned above. In AOD mode, users can choose whether to turn on the full-aod function.

[0071] The gamma curves used in other display modes may include gamma curves corresponding to different display areas, and may also include gamma curves corresponding to different frame rates.

[0072] See Table 1, which shows a schematic diagram of a gamma curve structure according to an embodiment of the present disclosure.

[0073] Table 1

[0074]

[0075] MEM1 area, MEM2 area and MEM3 area may represent different storage areas, which may be used to store display-related configuration information, such as a gamma curve for a specific display mode. Harea and L area may correspond to different display areas on the display screen.

[0076] ADD00-ADD03, ADD10-ADD13 may respectively represent gamma curves for normal display mode, wherein each set of gamma curves (eg ADD00 is a set of gamma curves) may include one or more gamma curves. ADD01-ADD03, ADD11-ADD13 may respectively correspond to different high frame rate display configurations (High frame rate 1-3).

[0077] ADD30~ADD32 can represent gamma curves for some uncommon but required display modes. ADD30 can represent the gamma curve for the screen-off display mode (aod in the table), ADD31 can represent the gamma curve for the fixed frame rate display mode (fps in the table), and ADD32 can represent the gamma curve for the virtual reality display mode (Vr in the table) or the high dynamic range display mode (hdr in the table).

[0078] In the embodiment of the present disclosure, the preset gamma curve for other display modes may be the gamma curve for normal display mode in the above table. That is, when the full-aod function is turned on, a set of unused gamma curves among ADD00-ADD03, ADD10-ADD13 may be obtained as the preset gamma curve, and which set of gamma curves to obtain as the preset gamma curve may be preset by the user as needed.

[0079] The preset gamma curve can be associated with any display area, for example, a set of gamma curves corresponding to the H area or a set of gamma curves corresponding to the L area. The preset gamma curve can also be associated with any frame rate, for example, a set of gamma curves corresponding to the High frame rates 1-3.

[0080] The number of gamma curves included in the preset gamma curve (such as any one of ADD00~ADD03, ADD10~ADD13) is usually greater than the number of gamma curves included in the gamma curve used for the AOD mode (i.e., the original gamma curve, such as the above-mentioned ADD30). For example, ADD30 may only include 4 to 6 gamma curves, while any one of ADD00~ADD03, ADD10~ADD13 may include 10 to 14 gamma curves. In the embodiment of the present disclosure, by replacing the original gamma curve with the preset gamma curve at the beginning of the full-aod function, a better display effect can be achieved in the screen-off display mode.

[0081] In step S201, you can:

[0082] In response to the screen-off display mode being turned on and the screen-off display function being turned on, an address of a preset gamma curve is obtained from a register; and based on the address of the preset gamma curve, the preset gamma curve is addressed and obtained.

[0083] The address of the preset gamma curve may be a physical address of the preset gamma curve in a memory, and the address of the preset gamma curve may be stored in a register.

[0084] Step S202: replacing the original gamma curve used for the screen-off display mode with a preset gamma curve as a target gamma curve.

[0085] The method may further include:

[0086] In response to the screen-off display mode being turned on and the screen-off display function being turned off, an original gamma curve for the screen-off display mode is acquired; and the original gamma curve is used as a target gamma curve.

[0087] That is to say, when the screen-off display mode is turned on, the user can still choose to turn off the full-aod function as needed, so that the original gamma curve can be used to process the image to be displayed.

[0088] See also Figure 3 , shows a schematic diagram of the design of a screen-off display control system according to an embodiment of the present disclosure. Figure 3 As shown, it may include a register, a full-aod enable module and three selectors (Mux0, Mux1 and Mux2). Among them, the register can be used to store the full-aod-mod signal value and the address of the preset gamma curve, and the full-aod-mod signal can be used to control whether to turn on the screen display function. When the full-aod-mod signal value is 1, it means that the screen display function is turned on, and when the full-aod-mod signal value is 0, it means that the screen display function is turned off.

[0089] by Figure 3 Taking the structure shown as an example, in step S201, the screen-off display mode is turned on, that is, the aod_en signal value input to the full-aod enable module is 1, and the screen-off display function is turned on, that is, the full-aod-mod signal value transmitted by the register is also 1. At this time, the full-aod_en signal output by the full-aod enable module is 1. When full-aod_en=1, Mux0 can select the address of the preset gamma curve stored in the register as output, and obtain the preset gamma curve from the memory as the target gamma curve.

[0090] When the aod_en signal value input to the full-aod enable module is 1, and the full-aod-mod signal value passed by the register is 0, it means that the user chooses not to use the screen-off display function when the screen-off display mode is turned on. At this time, the full-aod_en signal output by the full-aod enable module is 0. When full-aod_en=0, Mux0 can select the address of the original gamma curve originally input from other modules as the output, and obtain the original gamma curve from the memory as the target gamma curve.

[0091] Step S203 , processing the image to be displayed based on the target gamma curve to obtain a processed image to be displayed.

[0092] For example, the brightness of the image to be displayed may be adjusted based on the target gamma curve, and the adjustment method may be implemented based on the existing technology, so as to obtain a processed image to be displayed.

[0093] Among them, the processed image to be displayed can be used to display in the screen-off display mode.

[0094] According to an embodiment of the present disclosure, in response to the screen-off display mode being turned on and the screen-off display function being turned on, a preset gamma curve for other display modes is obtained, and the original gamma curve for the screen-off display mode is replaced with the preset gamma curve as the target gamma curve, and the image to be displayed is processed based on the target gamma curve to obtain the processed image to be displayed in the screen-off display mode. This can achieve the allocation of gamma curves in other modes with better display effects to the screen-off display mode, so that the screen-off display mode can have higher display accuracy and achieve better display effects, so as to meet diverse application requirements, be more flexible, and enhance user experience.

[0095] In step S203, it is also possible to:

[0096] The image to be displayed is processed based on the target gamma curve and the target pulse width modulation parameters to obtain a processed image to be displayed.

[0097] Among them, in response to the screen-off display mode being turned on and the pulse width modulation (PWM) function being turned on, the target pulse width modulation parameters are the preset pulse width modulation parameters for other display modes; in response to the screen-off display mode being turned on and the pulse width modulation function being turned off, the target pulse width modulation parameters are the pulse width modulation parameters for the screen-off display mode.

[0098] The user can set whether to turn on the pulse width modulation function as needed. The target pulse width modulation parameters may include duty cycle, frequency, etc. After adjusting the brightness of the image to be displayed based on the target gamma curve, the brightness, pixel state, etc. of the image to be displayed can be further fine-tuned based on the target pulse width modulation parameters. The specific process of adjusting using the target pulse width modulation parameters can be implemented based on existing technology.

[0099] See also Figure 3 , the control signal pre-stored in the register can be used to control whether to turn on the pulse width modulation function (its design can refer to the screen-off display function). When the pulse width modulation function is indicated to be turned on, Mux1 can select the address of the preset pulse width modulation parameters for other display modes (the preset pulse width modulation parameters in the figure) as the address output of the target pulse width modulation parameters; when the pulse width modulation function is indicated to be turned off, Mux1 can select the address of the pulse width modulation parameters for the screen-off display mode (the original pulse width modulation parameters in the figure) as the address output of the target pulse width modulation parameters. Based on the address of the target pulse width modulation parameters, the target pulse width modulation parameters can be addressed from the memory. Thereby, the screen-off display scheme disclosed in the present invention can be made more flexible, and a better screen-off display effect can be obtained when the pulse width modulation function is turned on.

[0100] In step S203, it is also possible to:

[0101] The image to be displayed is processed based on the target gamma curve and the target pixel interface control parameter to obtain a processed image to be displayed.

[0102] Among them, in response to the screen-off display mode being turned on and the pixel interface control (Pixel Interface Controller, PIC) function being turned on, the target pixel interface control parameters are the preset pixel interface control parameters for other display modes; in response to the screen-off display mode being turned on and the pixel interface control function being turned off, the target pixel interface control parameters are the pixel interface control parameters for the screen-off display mode.

[0103] The user can set whether to turn on the pixel interface control function as needed. The target pixel interface control parameters may include pixel switch status, pixel brightness, color information, etc. After adjusting the brightness of the image to be displayed based on the target gamma curve, the display effect of each pixel in the image to be displayed can be further fine-tuned based on the target pixel interface control parameters. The specific process of adjusting using the target pixel interface control parameters can be implemented based on existing technology.

[0104] See also Figure 3, the control signal pre-stored in the register can be used to control whether to turn on the pixel interface control function (its design can refer to the screen-off display function). When the pixel interface control function is indicated to be turned on, Mux2 can select the address of the preset pixel interface control parameters for other display modes (the preset pixel interface control parameters in the figure) as the address output of the target pulse width modulation parameters; when the pixel interface control function is indicated to be turned off, Mux2 can select the address of the pixel interface control parameters for the screen-off display mode (the original pixel interface control parameters in the figure) as the address output of the target pixel interface control parameters. Based on the address of the target pixel interface control parameters, the target pixel interface control parameters can be addressed from the memory. Thereby, the screen-off display scheme disclosed in the present invention can be made more flexible, and a better screen-off display effect can be obtained when the pixel interface control function is turned on.

[0105] The image to be displayed can also be processed based on the target gamma curve, the target pixel interface control parameter and the target pulse width modulation parameter to obtain a processed image to be displayed. At this time, it can be determined whether the screen off display function, the pulse width modulation function and the pixel interface control function are turned on in the screen off display mode, and the processing of the image to be displayed can be realized based on the above method.
