[0005] A method is provided. The method can be executed in an electronic device including at least one processor, a display driving circuit, and a display panel. The method can include an operation of transmitting data including a first image to be displayed on a display area of ​​the display panel from the at least one processor to the display driving circuit. The method can include an operation of generating, by the at least one processor, a second image to be displayed on a first portion of the display area while the first image is displayed on the display area. The method can include an operation of identifying, by the at least one processor, a portion of the first image displayed on a second portion of the display area adjacent to the first portion of the display area.

[0014] FIG. 12 is a block diagram of a display module according to various embodiments.

[0015] Figure 13 is a schematic diagram of an exemplary AI (artificial intelligence) system.

[0016] FIG. 1 illustrates an example of multi-frequency driving in which display on a first part of a display area of ​​a display panel is executed at a first refresh rate while display on a second part of the display area is executed at a second refresh rate higher than the first refresh rate.

[0017] Referring to FIG. 1, an electronic device (100) may include a display (e.g., display (230) of FIG. 2). The display may include a display panel (e.g., display panel (232) of FIG. 2). The display panel may include a display area (110) (or active area (110)) that is viewable from a front side of the electronic device (100). The display area (110) may define at least a portion of the front side of the electronic device (100). The display area (110) may be usable for displaying a screen viewable from the front side of the electronic device (100). For example, the display area (110) may be used for displaying a screen (190).

[0018] A screen (190) displayed on a display area (110) may include a first portion (191), a second portion (192), and a third portion (193). The first portion (191) of the screen (190), the second portion (192) of the screen (190), and the third portion (193) of the screen (190) may be displayed simultaneously at one (a) timing or within one (a) time interval. The first portion (191) of the screen (190) may be displayed on the first portion (111) of the display area (110). The second portion (192) of the screen (190) may be displayed on the second portion (112) of the display area (110) while the first portion (191) of the screen (190) is displayed on the first portion (111) of the display area (110). The third part (193) of the screen (190) can be displayed on the third part (113) of the display area (110) while the first part (191) of the screen (190) is displayed on the first part (111) of the display area (110) and the second part (192) of the screen (190) is displayed on the second part (112) of the display area (110).

[0019] For example, the first part (191) of the screen (190) may be used to provide the status of the electronic device (100). The first part (191) of the screen (190) may be an indicator area. For example, the second part (192) of the screen (190) and the third part (193) of the screen (190) may be used to provide a user interface (or execution screen) of a software application. The second part (192) of the screen (190) may represent a sub-region of the user interface that provides one or more contents whose status changes (over time) independently (or regardless) of whether a user input for the electronic device (100) is received. The third part (193) of the screen (190) may represent a sub-region of the user interface that provides one or more contents whose status changes on the condition that a user input for the electronic device (100) is received. The second portion (192) of the screen (190) may represent a sub-region of the user interface that is used to provide one or more other contents whose state changes more frequently than one or more contents provided within the third portion (193) of the screen (190). As a non-limiting example, the second portion (192) of the screen (190) may represent a sub-region of the user interface that provides a moving picture that is being played, and the third portion (193) of the screen (190) may represent a sub-region of the user interface that provides visual information (e.g., still images, text, characters, graphical objects, and / or visual objects) related to the moving picture.

[0020] For example, a processor (e.g., at least one processor (210) of FIG. 2) (e.g., including a processing circuit) of an electronic device (100), which is a hardware component of the electronic device (100), may obtain an image provided through a first portion (191) of a screen (190) in response to an event that causes a change in a state of the electronic device (100). For example, the processor may obtain (or generate) one or more images provided through a second portion (192) of the screen (190) and a third portion (193) of the screen (190) using the software application. As a non-limiting example, the processor may use the software application to (newly (or additionally)) generate (or acquire) one or more images to be provided through the second portion (192) of the screen (190) every first period, and may use the software application to (newly (or additionally)) generate (or acquire) one or more images to be provided through the third portion (193) of the screen (190) every second period, which is longer than the first period. As a non-limiting example, the processor may use the software application to periodically acquire one or more images to be provided through the second portion (192) of the screen (190) independently of whether a user input is received with respect to the user interface, and may use the software application to acquire one or more images to be provided through the third portion (193) of the screen (190) on the condition that a user input is received with respect to the user interface.

[0021] The state of the second part (192) of the screen (190) may change more frequently than the state of the first part (191) of the screen (190) and the state of the third part (193) of the screen (190). The state of the second part (192) of the screen (190) may change while the states of the first part (191) of the screen (190) and the third part (193) of the screen (190) are maintained.

[0022] Since the speed of change of the state of the second part (192) of the screen (190) is faster than the speed of change of the state of the first part (191) of the screen (190) and the speed of change of the state of the third part (193) of the screen (190), the second refresh rate suitable for providing the second part (192) of the screen (190) may be higher than the first refresh rate suitable for providing the first part (191) of the screen (190) and the third refresh rate suitable for providing the third part (193) of the screen (190). As a non-limiting example, since the second refresh rate is higher than the first refresh rate and the third refresh rate, performing display on the first area (191) of the screen (190) at the first refresh rate and performing display on the third area (193) of the screen (190) at the third refresh rate while performing display on the second area (192) of the screen (190) at the second refresh rate can be utilized within the electronic device (100) to reduce power consumption. For example, the electronic device (100) can display the second area (192) of the screen (190) at the second refresh rate while displaying the first area (191) of the screen (190) at the first refresh rate and displaying the third area (193) of the screen (190) at the third refresh rate, using less power than the power consumed by providing the screen (190) at the second refresh rate. As a non-limiting example, the third playback rate may be different from the first playback rate. As a non-limiting example, the third playback rate may be the same as the first playback rate.

[0023] The electronic device (100) may perform display on a second part (112) of the display area (110) at the second refresh rate while performing display on a first part (111) of the display area (110) at the first refresh rate to display a second part (112) of the display area (110) at the second refresh rate while displaying a first area (191) of the screen (190) and a third area (193) of the screen (190) at the first refresh rate, in order to display a second part (192) of the screen (190) at the second refresh rate. For example, driving (or controlling) (or causing) the display (or the display panel) to perform display on a second part (112) of the display area (110) at the second refresh rate while performing display on a first part (111) of the display area (110) at the first refresh rate may be referred to as multi-frequency driving. For example, the electronic device (100) may include components (e.g., hardware components) for the multi-frequency driving. The components are exemplified in the description of FIG. 2.

[0024] Figure 2 is a simplified block diagram of an exemplary electronic device.

[0025] Referring to FIG. 2, the electronic device (100) may include at least one processor (210), memory (220), and display (230).

[0026] At least one processor (210) may be a hardware component of the electronic device (100) that is available to execute (or perform) at least some of the operations exemplified in the above and below descriptions. At least one processor (210) may include processing circuitry or processing integrated circuitry. For example, at least one processor (210) may include a central processing unit (CPU) (e.g., including processing circuitry), a graphics processing unit (GPU) (e.g., including processing circuitry), and / or a display processing unit (DPU) (e.g., including processing circuitry). At least one processor (210) may be implemented as a system on chip (SoC). At least one processor (210) may comprise a processor assembly. At least one processor (210) may include at least a portion of the processor (1120) of FIG. 11 or may correspond to at least a portion of the processor (1120) of FIG. 11.

[0027] The memory (220) may include one or more storage media (or one or more storage devices). For example, the memory (220) may comprise a memory assembly comprising one or more storage media. For example, the one or more storage media may include a hard drive, flash memory, permanent memory such as read-only memory (ROM), semi-permanent memory such as random access memory (RAM), any other suitable type of storage (or storage assembly), or any combination thereof. The memory (220) may include a cache memory, which is one or more different types of memory used to temporarily store data for a function or feature of the electronic device (100). As a non-limiting example, the cache memory may be included within at least one processor (210).

[0028] The memory (220) may be fixedly embedded within the electronic device (100) or incorporated into one or more suitably types of components (e.g., a subscriber identity module (SIM) card and / or a secure digital (SD) card) that can be repeatedly inserted into and removed from the electronic device (100).

[0029] The memory (220) may store one or more software applications, such as an operating system (or system software application), a firmware software application, a driver software application, a plug-in (e.g., add-in, add-on, and / or applet) software application, and / or any other suitable software applications. The one or more software applications may include instructions executable by at least one processor (210). The memory (220) may store instructions callable by an application programming interface (API). The memory (220) may store instructions within a library.

[0030] The memory (220) may include at least a portion of the memory (1130) of FIG. 11 or correspond to at least a portion of the memory (1130) of FIG. 11.

[0031] At least one processor (210) and memory (220) may be described as a host processor.

[0032] The display (230) may be a hardware component of the electronic device (100) that is available to perform at least some of the operations exemplified in the above and below descriptions. The display (230) may include at least a portion of the display module (1160) of FIGS. 11 and 12 or may correspond to at least a portion of the display module (1160) of FIGS. 11 and 12. The display (230) may include a display driver circuit (231) (e.g., including at least a portion of the display driver IC (1230) of FIG. 12 or corresponding to at least a portion of the display driver IC (1230) of FIG. 12) and a display panel (232) (e.g., including at least a portion of the display (1210) of FIG. 12 or corresponding to at least a portion of the display (1210) of FIG. 12).

[0033] The display driving circuit (231) may be a hardware component of an electronic device (100) that can be used to display a screen (or one or more images) on a display panel (232) (or on a display area (e.g., a display area (110)) of the display panel (232). The display driving circuit (231) may be configured to receive data (e.g., frame data) from at least one processor (210) and control the display panel (232) to display the screen (or one or more images) using the data. The display driving circuit (231) may be described as a display peripheral (231).

[0034] The display panel (232) may be a hardware component of an electronic device (100) that is available to display a screen (or one or more images). For example, the display panel (232) may be configured to display the screen (or one or more images) under the control of a display driving circuit (231).

[0035] The electronic device (100) may include one or more interfaces (or one or more paths) that electrically and / or physically connect the display driving circuit (231) to at least one processor (210).

[0036] The one or more interfaces (or the one or more paths) may include an interface (241) (or path (241)). The interface (241) may be a hardware component of the electronic device (100) that is available for data (e.g., frame data) transmitted from at least one processor (210) to the display driver circuit (231). As a non-limiting example, the interface (241) may include a mobile industry processor interface (MIPI). As a non-limiting example, the interface (241) may be operated (or driven) for a command mode of the MIPI display serial interface (DSI) (or according to a command mode of the MIPI DSI). The display driver circuit (231) connected to the interface (241) used for the command mode may include a graphic random access memory (GRAM). As a non-limiting example, the interface (241) may be operated (or driven) for a video mode of MIPI DSI (or according to a video mode of MIPI DSI). The display driver circuit (231) connected to the interface (241) used for the video mode may not include a GRAM. As a non-limiting example, the interface (241) may be operated (or driven) for a video hybrid mode (or according to a video hybrid mode). The display driver circuit (231) connected to the interface (241) used for the video hybrid mode may include a GRAM. As a non-limiting example, the interface (241) may be operated (or driven) according to an adaptive refresh panel (ARP) of MIPI DSI. The display driver circuit (231) connected to the interface (241) used for the ARP may not include a GRAM.

[0037] The display driving circuit (231) may be configured to perform a scan for display on a part of the display area (e.g., display area (110)) of the display panel (232) and to refrain from (or bypass) (or skip) a scan for display on another part of the display area within one time interval for display on the display panel (232). Since the display driving circuit (231) is configured to perform the scan for display on the part of the display area (e.g., the first part of the display area) and to refrain from scanning for display on the other part of the display area (e.g., the second part of the active area), the display (230) (or the display driving circuit (231)) can support the multi-frequency driving. For example, as illustrated in the description of FIG. 1, since the display driving circuit (231) is configured to perform the scan for display on the part of the display area and to refrain from scanning for display on the other part of the display area according to the multi-frequency driving, the display driving circuit (231) can perform display on the second part of the display area according to a refresh rate that is different from the refresh rate for display on the first part of the display area.

[0038] For example, the display driving circuit (231) may display a first image received from the at least one processor according to a first refresh rate on the first part of the display area of ​​the display panel (232), while displaying a second image received from the at least one processor according to a second refresh rate different from the first refresh rate on the second part of the display area.

[0039] The first refresh rate may be described as a refresh rate targeted (or identified) (or recognized) (or scheduled) by at least one processor (210) for an image to be displayed on the first portion of the display area. The first refresh rate may correspond to a time interval scheduled by the at least one processor (210) to transmit the image to be displayed on the first portion of the display area from the at least one processor (210) to the display driving circuit (231) via the interface (241). The first refresh rate may correspond to a time period during which the first image is maintained on the display panel (232).

[0040] The second refresh rate may be described as a refresh rate targeted (or identified) (or recognized) (or scheduled) by at least one processor (210) for an image displayed on the second portion of the display area. The second refresh rate may correspond to a time interval scheduled by the at least one processor (210) to transmit the image displayed on the second portion of the display area from the at least one processor (210) to the display driving circuit (231) via the interface (241). The second refresh rate may correspond to a time period during which the second image is maintained on the display panel (232).

[0041] The display driving circuit (231) can perform display on a first part of the display panel (232) (or a first part of the display area of ​​the display panel (232)) using data received from at least one processor (210) (or a processor (e.g., DPU)) based on the first refresh rate, and can perform display on a second part of the display panel (232) (or a second part of the display area) using data received from at least one processor (210) (or a processor (e.g., DPU)) based on the second refresh rate.

[0042] The display driver circuit (231) may perform processing on the image before performing a scan on the image to be displayed on the display area. The processing may include local processing, image processing, and / or pixel processing. As a non-limiting example, the processing may be performed at least in part using the AI ​​system described with reference to FIG. 13. For example, the processing may include adjusting the viewing angle of at least a portion of the image for user privacy. For example, the processing may include performing local tone mapping with respect to a portion of the display area. The local tone mapping may be performed by the display driver circuit (231) using position information provided to the display driver circuit (231) from at least one processor (210) (e.g., position information of a portion of the display area to which the local tone mapping will be applied). For example, the processing may include decompressing compressed data (e.g., including the image) by at least one processor (210) to improve the quality of the image displayed on the display area.

[0043] For example, at least one processor (210) can encode data including the image and transmit the encoded data to the display driver circuit (231) via the interface (241). Encoding the data may include compressing the data for the quality of the image. Compressing the data may be described as display stream compression (DSC). The display driver circuit (231) can receive the encoded data from the at least one processor (210) via the interface (241). The display driver circuit (231) can perform the processing based on decoding the encoded data. The display driver circuit (231) can display the image on the display area based on performing a scan on the image included in the decoded data.

[0044] At least one processor (210) (or the DPU) can transmit data including a first image to be displayed on the display area to the display driving circuit (231) via the interface (241). The data including the first image can be encoded by the at least one processor (210). The display driving circuit (231) can receive the encoded data from the at least one processor (210) via the interface (241). The display driving circuit (231) can decode the encoded data. The display driving circuit (231) can display the first image on the display area based on performing a scan on the first image included in the decoded data.

[0045] At least one processor (210) (or the CPU) may generate (or obtain) a second image to be displayed on a first portion (e.g., a second portion (112) of the display area (110)) of the display area while the first image is displayed on the display area (e.g., the display area (110)). As a non-limiting example, the second image may be generated (or obtained) via a software application in a memory (220) executed by the at least one processor (210). The at least one processor (210) may perform encoding (or processing) with respect to the second image to change a first portion of the first image displayed on the first portion (e.g., the second portion (112) of the display area (110)) of the display area according to multi-frequency driving, and to maintain a second portion of the first image, which is different from the first portion of the first image, on the display area (e.g., the display area (110)). For example, at least one processor (210) (or the DPU) may identify, for the encoding, a portion of the first image displayed on a second portion of the display area relative to the first portion of the display area where the second image is to be displayed. At least one processor (210) (or the DPU) may encode data including the portion of the first image and the second image, and transmit the encoded data to the display driving circuit (231) via the interface (241).

[0046] The display driving circuit (231) can receive the encoded data from at least one processor (210) via the interface (241). The display driving circuit (231) can decode the encoded data. The display driving circuit (231) can, based on performing a scan on the part of the first image and the second image included in the decoded data, display the part of the first image again, change the first part of the first image to the second image, and maintain the other part of the first image. Since the part of the first image is displayed again (or additionally scanned) differently from the other part of the first image according to performing a scan on the part of the first image and the second image, a difference may occur between the visibility of the part of the first image and the visibility of the other part of the first image. The above difference can be more easily recognized by a user when the content provided through the part of the first image and the content provided through the other part of the first image are identical. The above difference is explained with reference to FIG. 3.

[0047] Figure 3 illustrates an example of position information of a first part of a display area.

[0048] Referring to FIG. 3, at least one processor (210) can encode data including a first image (310) and transmit the encoded data to a display driving circuit (231) via an interface (241). The display driving circuit (231) can receive the encoded data from the display driving circuit (231) via the interface (241). The display driving circuit (231) can display the first image (310) on the display area based on decoding the encoded data and performing a scan on the first image (310) included in the decoded data.

[0049] The first image (310) displayed on the display area may include a first portion (311) displayed on a first part of the display area, and a second portion (312) different from the first portion (311) of the first image (310). The first portion (311) of the first image (310) displayed on the display area may be at least partially surrounded by a third portion (313) of the first image (310).

[0050] At least one processor (210) can obtain a second image (320) to be displayed on the first portion of the display area while the first image (310) is displayed on the display area according to the scan for the first image (310). The at least one processor (210) can identify a third portion (313) of the first image (310) displayed on the second portion of the display area related to the first portion of the display area for encoding data to be transmitted to the display driving circuit (231) in relation to the second image (320). The at least one processor (210) can perform the encoding using a third image (330) including the third portion (313) of the first image (310) and the second image (320). At least one processor (210) can transmit the data, which includes a third image (330) and is encoded by the at least one processor (210), to the display driving circuit (231) via the interface (241).

[0051] The display driving circuit (231) can receive the data from at least one processor (210) via the interface (241). The display driving circuit (231) can decode the data. The display driving circuit (231) can perform a scan on a third image (330) included in the decoded data (e.g., including a third part (313) of the first image (310) and a second image (320). The third part (313) of the first image (310) can be displayed again according to the scan on the third image (330). The second image (320) can be changed from the first part (311) of the first image (310) according to the scan on the third image (330). The fourth part (314) of the first image (310) may be maintained on the display area, unlike the third part (313) of the first image (310) which is re-displayed according to the scan for the third image (330).

[0052] As a non-limiting example, the content provided by the third portion (313) of the first image (310) may be identical to the content provided by the fourth portion (314) of the first image (310) and different from the content provided by the second image (320). The content provided by the third portion (313) of the first image (310) may be identical to the content provided by the fourth portion (314) of the first image (310), but because the third portion (313) of the first image (310) is re-displayed according to the scan for the third image (330), unlike the fourth portion (314) of the first image (310), a difference may occur between the visibility of the third portion (313) of the first image (310) and the visibility of the fourth portion (314) of the first image (310). For example, the content provided by the third part (313) of the first image (310) and the content provided by the fourth part (314) of the first image (310) may have a first color (e.g., white), and the content provided by the second image (320) may have a second color (e.g., black). Both the content provided by the third part (313) of the first image (313) and the content provided by the fourth part (314) of the first image (314) have the first color, but since the third part (313) of the first image (310) is re-displayed according to the scan for the third image (330), unlike the fourth part (314) of the first image (310), a color difference between the third part (313) of the first image (313) and the fourth part (314) of the first image (314) may occur on the display area. This color difference may be perceived by the user at the boundary (331) between the third part (313) of the first image (310) (or the third image (330)) and the fourth part (314) of the first image (310) (and / or around the boundary (331)).The above color difference perceived by the user may reduce the quality of the service provided through the display (230).

[0053] The display driving circuit (231) may perform a scan on the second image (320) (instead of performing a scan on the third image (330)) to reduce the color difference perceived by the user. Since the second image (320) is an image that is generated (or newly generated) (or additionally generated) while the first image (310) is displayed on the display area, the content provided by the second image (320) may be visually different from the content provided by the third portion (313) of the first image (310). For example, the content provided by the third portion (313) of the first image (310) may have the first color, while the content provided by the second image (320) may have the second color. For example, since the content provided by the second image (320) is visually different from the content provided by the third portion (313) of the first image (310), differences in visual characteristics that occur at the boundary (321) between the third portion (313) of the first image (310) and the second image (320) upon scanning the second image (320) may not be perceived by the user. For example, the difference may be unnoticeable to the user.

[0054] A scan for the second image (320) may be performed based on identifying the second image (320) included in the third image (330). At least one processor (210) may transmit first position information of the first part of the display area where the second image (320) is to be displayed, to the display driving circuit (231), to cause (or control) (or assist) the display driving circuit (231) to identify the second image (320) included in the third image (330). At least one processor (210) may transmit the first position information to the display driving circuit (231), to cause (or control) the display driving circuit (231) to perform the scan for the second image (320).

[0055] The first position information may be distinguished from second position information of a portion (340) of the display area corresponding to a third image (330) transmitted from at least one processor (210) to the display driving circuit (231). The first position information may indicate a position of a scan to be performed by the display driving circuit (231), and the second position information may indicate a position at which an image in the data transmitted from at least one processor (210) is to be displayed. The first position information may indicate a position of an image to be displayed on the display area, and the second position information may indicate a position of an image transmitted from at least one processor (210) to the display driving circuit (231) via an interface (241).

[0056] For example, the first position information may indicate a start position of the first part of the display area and an end position of the first part of the display area. As a non-limiting example, the first position information may include data of a position of an upper left corner (333) of the first part of the display area corresponding to the start position (e.g., panel refresh start column (PRSC) and panel refresh start row (PRSR)) and data of a position of a lower right corner (334) of the first part of the display area corresponding to the end position (e.g., panel refresh end column (PREC) and panel refresh end row (PRER)).

[0057] For example, the second location information may indicate a start position of a part (340) of the display area and an end position of the part (340) of the display area. As a non-limiting example, the second location information may include data of a position of an upper left corner (341) of a part (340) of the display area corresponding to the start position (e.g., a start column address (SC) and a start page address (SP)) and data of a position of a lower right corner (342) of a part (340) of the display area corresponding to the end position (e.g., an end column address (EC) and an end page address (EP)).

[0058] The first location information may be transmitted from at least one processor (210) to the display driving circuit (231) before transmitting the data including the third image (330) from at least one processor (210) to the display driving circuit (231). For example, the first location information may be transmitted at a time point (or timing) prior to a reference time from a start time point (or start timing) of a vertical synchronization signal (e.g., the second vertical synchronization signal below) for transmitting the data including the third image (330). For example, the first location information may be transmitted from at least one processor (210) to the display driving circuit (231) via a front porch portion of the first vertical synchronization signal prior to the second vertical synchronization signal. The first location information may be included in a command transmitted from at least one processor (210) to the display driving circuit (231).

[0059] The second location information may be transmitted from at least one processor (210) to the display driving circuit (231) before transmitting the data including the third image (330) from at least one processor (210) to the display driving circuit (231). For example, the second location information may be transmitted at a time point (or timing) prior to a reference time from a start time point (or start timing) of a vertical synchronization signal (e.g., the second vertical synchronization signal below) for transmitting the data including the third image (330). For example, the second location information may be transmitted from at least one processor (210) to the display driving circuit (231) via a front porch portion of a first vertical synchronization signal prior to the second vertical synchronization signal. The second location information may be included in a command transmitted from at least one processor (210) to the display driving circuit (231).

[0060] The first location information may be transmitted through the interface (241). The second location information may be transmitted through the interface (241). However, the present invention is not limited thereto. The first location information may be transmitted from at least one processor (210) to the display driving circuit (231) through another interface distinct from the interface (241). The second location information may be transmitted from at least one processor (210) to the display driving circuit (231) through the other interface.

[0061] Transmitting the second position information from at least one processor (210) to the display driving circuit (231) may be performed under a condition that the position of at least a portion of the display area related to the image transmission from at least one processor (210) to the display driving circuit (231) changes. For example, when the position of at least a portion of the display area related to the image transmission is maintained, transmitting the second position information may not be performed independently of the change in the position of at least a portion of the display area related to the scan performed for display. For example, when the position of at least a portion of the display area related to the image transmission changes, transmitting the second position information may be performed.

[0062] The use of the first location information and the use of the second location information are explained with reference to FIGS. 4 to 6.

[0063] FIG. 4 illustrates first position information of a first part of a display area for operation of a display driving circuit performed using a GRAM (graphic random access memory), and second position information of a third part of a display area including the first part of the display area and the second part of the display area.

[0064] Referring to FIG. 4, the electronic device (100) may include a display host (400). The display host (400) may include a CPU (401) (or CPU / GPU (401)), a DPU (402), and a memory (220). At least one processor (210) may include a CPU (401) and a DPU (402).

[0065] The display driving circuit (231) can display a first image (310) on the display area. The CPU (401) can generate a second image (320) while the first image (310) is displayed on the display area. The CPU (401) can store (411) the second image (320) in the memory (220). The CPU (401) can transmit (412) (or provide) the first location information of the first part of the display area where the second image (320) is to be displayed to the DPU (402).

[0066] The DPU (402) can acquire (413) (or identify) data to be input to the encoder (403) using the first position information from the CPU (401). Acquiring (413) data to be input to the encoder (403) using the first position information is described with reference to FIG. 5.

[0067] Figure 5 illustrates identifying a portion of the first image.

[0068] Referring to FIG. 5, the memory (220) may include a storage area for transmitting images from at least one processor (210) to the display driving circuit (231). The storage area may be divided (or segmented) into a plurality of areas (500), each corresponding to a unit of encoding performed via the encoder (403). The plurality of regions (500) may include a first region (500-1), a second region (500-2), a third region (500-3), a fourth region (500-4), a fifth region (500-5), a sixth region (500-6), a seventh region (500-7), an eighth region (500-8), a ninth region (500-9), a tenth region (500-10), an eleventh region (500-11), a twelfth region (500-12), a thirteenth region (500-13), and a fourteenth region (500-14).

[0069] The DPU (402) can identify that a first part (510-1) of an area (510) within the storage area corresponding to the first location information of the first part of the display area where the second image (320) is to be displayed is included in a fifth area (500-5), a second part (510-2) of the area (510) is included in a sixth area (500-6), a third part (510-3) of the area (510) is included in a seventh area (500-7), and a fourth part (510-4) of the area (510) is included in an eighth area (500-8). Based on the above identification, the DPU (402) can obtain data (491) including a third image (330) including a third part (313) of the first image (310) and a second image (320) from the fifth area (500-5), the sixth area (500-6), the seventh area (500-7), and the eighth area (500-8) of the storage area of ​​the memory (220).

[0070] Referring again to FIG. 4, the DPU (402) may input data (491) to the encoder (403) based on obtaining (413) data (491) including a third image (330). The DPU (402) may perform encoding on the data (491) using the encoder (403) to obtain encoded data (492) (414). As a non-limiting example, the encoded data (492) may include a compressed third image (330).

[0071] The DPU (402) may transmit (415) encoded data (492) to the display driver circuit (231) via a transmission interface (441) (e.g., including a transmission circuit) within the DPU (402) connected to the interface (241). Transmitting (415) encoded data (492) may be performed based on transmitting (421) the second location information to the transmission interface (441). As a non-limiting example, the DPU (402) may transmit (416) the first location information to the display driver circuit (231) before transmitting (415) the encoded data (492). As a non-limiting example, the DPU (402) may transmit (415) the second location information to the display driver circuit (231).

[0072] The display driving circuit (231) can receive encoded data (492) (or data corresponding to the encoded data (492)) from the DPU (402) via a receiving interface (442) (e.g., including a receiving circuit) within the display driving circuit (231) connected to the interface (241). As a non-limiting example, the display driving circuit (231) can receive the first location information and / or the second location information from the DPU (402) via the receiving interface (442).

[0073] The display driving circuit (231) can perform (426) storing the encoded data (492) in the GRAM (404) within the display driving circuit (231). As a non-limiting example, the display driving circuit (231) operating for the command mode can identify, using the second position information, a location within the GRAM (404) where the encoded data (492) is to be stored, and, based on the identification, store (426) the encoded data (492) in the GRAM (404). As a non-limiting example, the display driving circuit (231) operating for the video hybrid mode can identify, using the second position information, a location within the GRAM (404) where the encoded data (492) is to be stored, and, based on the identification, store (426) the encoded data (492) in the GRAM (404). As a non-limiting example, the display driving circuit (231) operating for the video hybrid mode may, without using the second location information, identify a location within the GRAM (404) where the encoded data (492) is to be stored based on the time (or time interval) at which the encoded data (492) is received from the DPU (402), and, based on the identification, store (426) the encoded data (492) in the GRAM (404).

[0074] The display driving circuit (231) can obtain (417) encoded data (492) (or data corresponding to the encoded data (492)) (or a compressed third image (330)) from the GRAM (404). As a non-limiting example, the display driving circuit (231) can obtain (417) encoded data (492) using the second location information. The encoded data (492) obtained from the GRAM (404) can be data to be input to the decoder (405).

[0075] The display driving circuit (231) can input encoded data (492) to the decoder (405). The display driving circuit (231) can obtain data (491) (or decoded data) (418) by performing decoding on the encoded data (492) using the decoder (405). As a non-limiting example, the data (491) obtained by the display driving circuit (231) can include a decompressed third image (330), unlike the encoded data (492).

[0076] The display driving circuit (231) can acquire (419) (or identify) a second image (320) included in a third image (330) in the data (491) using the first location information. The display driving circuit (231) can perform a scan (420) on the second image (320) with respect to the first part of the display area. Based on the scan (420), the display driving circuit (231) can change the first part (311) of the first image (310) to the second image (320). Based on the scan (420), the display driving circuit (231) can maintain a second part (312) of the first image (310) that is different from the first part (311) of the first image (310) on the display area.

[0077] FIG. 6 illustrates first position information and second position information for operation of a display driving circuit performed without using GRAM.

[0078] Referring to FIG. 6, the electronic device (100) may include a display host (400). The display host (400) may include a CPU (401) (or CPU / GPU (401)), a DPU (402), and a memory (220). At least one processor (210) may include a CPU (401) and a DPU (402).

[0079] The display driving circuit (231) can display a first image (310) on the display area. The CPU (401) can generate a second image (320) while the first image (310) is displayed on the display area. The CPU (401) can store (411) the second image (320) in the memory (220). The CPU (401) can transmit (412) (or provide) the first location information of the first part of the display area where the second image (320) is to be displayed to the DPU (402).

[0080] The DPU (402) may acquire (413) (or identify) data to be input to the encoder (403) using the first position information from the CPU (401). The DPU (402) may input the data (491) to the encoder (403) based on the acquisition (413) of data (491) including a third part (313) of the first image (310) and a third image (330) including the second image (320). The DPU (402) may acquire (414) encoded data (492) by performing encoding on the data (491) using the encoder (403). As a non-limiting example, the encoded data (492) may include a compressed third image (330).

[0081] The DPU (402) may transmit (415) encoded data (492) to the display driver circuit (231) via a transmission interface (441) (e.g., including a transmission circuit) within the DPU (402) connected to the interface (241). Transmitting (415) encoded data (492) may be performed based on transmitting (421) the second location information to the transmission interface (441). As a non-limiting example, the DPU (402) may transmit (416) the first location information to the display driver circuit (231) before transmitting (415) the encoded data (492). As a non-limiting example, the DPU (402) may transmit (415) the second location information to the display driver circuit (231).

[0082] The display driving circuit (231) can receive encoded data (492) (or data corresponding to the encoded data (492)) from the DPU (402) via a receiving interface (442) (e.g., including a receiving circuit) within the display driving circuit (231) connected to the interface (241). As a non-limiting example, the display driving circuit (231) can receive the first location information and / or the second location information from the DPU (402) via the receiving interface (442).

[0083] The display driving circuit (231) can input (517) (or transmit) (or provide) encoded data (492) to the decoder (405). As a non-limiting example, inputting (517) encoded data (492) to the decoder (492) can be performed according to the second position information.

[0084] The display driving circuit (231) can input encoded data (492) to the decoder (405). The display driving circuit (231) can perform decoding on the encoded data (492) using the decoder (405) to obtain data (491) (or decoded data) (518). As a non-limiting example, the data (491) obtained by the display driving circuit (231) can include a decompressed third image (330), unlike the encoded data (492).

[0085] The display driving circuit (231) can acquire (519) (or identify) a second image (320) included in a third image (330) in the data (491) using the first location information. The display driving circuit (231) can perform a scan (520) on the second image (320) with respect to the first part of the display area. Based on the scan (520), the display driving circuit (231) can change the first part (311) of the first image (310) to the second image (320). Based on the scan (520), the display driving circuit (231) can maintain a second part (312) of the first image (310) that is different from the first part (311) of the first image (310) on the display area.

[0086] The descriptions made with respect to encoding performed by at least one processor (210) and decoding performed by the display driver circuit (231) are merely exemplary. The descriptions may be applied equally or similarly with respect to area processing.

[0087] For example, when the display driving circuit (231) uses the GRAM, at least one processor (210) can transmit data including a first image to be displayed on a display area of ​​a display panel (232) from the at least one processor (210) to the display driving circuit (231). The at least one processor (210) can generate a second image to be displayed on a first part of the display area while the first image is displayed on the display area. The at least one processor (210) can identify a second part of the display area adjacent to the first part of the display area to perform area processing with respect to the second image. The at least one processor (210) can transmit data including location information of the first part of the display area, location information of the second part of the display area, and the second image from the at least one processor (210) to the display driving circuit (231). The display driving circuit (231) can receive the data including the position information of the first part of the display area, the position information of the second part of the display area, and the second image from at least one processor (210). The display driving circuit (231) can store the data including the second image in the GRAM using the position information of the first part of the display area. The display driving circuit (231) can obtain the second data and the first part of the first image displayed on the second part of the display area from the GRAM using the position information of the first part of the display area and the position information of the second part of the display area.The display driving circuit (231) can perform the region processing with respect to the first part of the first image and the second image, and perform a scan on the second image on which the region processing has been performed.

[0088] For example, when the display driving circuit (231) does not use the GRAM, at least one processor (210) may transmit data including a first image to be displayed on a display area of ​​the display panel (232) from the at least one processor (210) to the display driving circuit (231). The at least one processor (210) may generate a second image to be displayed on a first portion of the display area while the first image is displayed on the display area. The at least one processor (210) may identify a portion of the first image displayed on a second portion of the display area adjacent to the first portion of the display area to perform region processing with respect to the second image. The at least one processor (210) may transmit data including location information of the first portion of the display area (e.g., corresponding to the first location information) and a third image including the portion of the first image and the second image from the at least one processor (210) to the display driving circuit (231). The display driving circuit (231) can receive the data including the position information of the first part of the display area and the third image from at least one processor (210). The display driving circuit (231) can identify the position information of the third part of the display area corresponding to the third image according to the time at which the data is received, and perform the region processing with respect to the third image. The display driving circuit (231) can obtain the second image from the third image on which the region processing has been performed. The display driving circuit (231) can perform a scan on the second image on which the region processing has been performed.

[0089] Transmitting the first location information and / or the second location information from at least one processor (210) to the display driving circuit (231) may be optional. The display driving circuit (231) may identify the first location information and / or the second location information according to a time (or time interval) (or timing) (or point in time) at which data including at least a portion of an image is received from at least one processor (210) via the interface (241). In other words, identifying the first location information and the second location information may be implemented in various ways. Transmitting an image from at least one processor (210) to the display driving circuit (231), which is performed in relation to the first location information and the second location information, is described with reference to FIGS. 7 to 10.

[0090] Figures 7 to 10 illustrate transmission of a second image performed in relation to first location information and second location information.

[0091] Referring to FIG. 7, at least one processor (210) and a display driving circuit (231) may operate for the video mode, the video hybrid mode, and / or the ARP.

[0092] The display panel (232) may have a horizontal direction (791) and a vertical direction (792). The display driving circuit (231) may sequentially perform scans in the horizontal direction (791) for display on the display area of ​​the display panel (232). The scans in the horizontal direction (791) may be sequentially performed in the vertical direction (792). For example, the display area of ​​the display panel (232) may include a first horizontal line and a second horizontal line extending in the horizontal direction (791), respectively. The first horizontal line and the second horizontal line may be arranged in the vertical direction (792). For example, the display driving circuit (231) may perform the scans sequentially performed in the vertical direction (792) by performing a scan in relation to the second horizontal line based on performing a scan in relation to the first horizontal line.

[0093] At least one processor (210) can generate a second image (772) to be displayed on a portion (780) of the display area while displaying a first image on the display area, such as in a state (700). At least one processor (210) can generate a third image (773) including a first portion (771) of the first image displayed on a portion (781) of the display area that at least partially surrounds the portion (780) of the display area, and the second image (772). At least one processor (210) can transmit data including the third image (773) to the display driving circuit (231) via the interface (241).

[0094] The display driving circuit (231) can receive the data including the third image (773) from at least one processor (210) via the interface (241). The data including the third image (773) can be received via a vertical synchronization signal (710). The vertical synchronization signal (710) can include a vertical front porch portion (711), a vertical active portion (712), and a vertical back porch portion (713). Since the time at which the data including the third image (773) is received from at least one processor (210) according to the video mode, the video hybrid mode, and / or the ARP corresponds to a position (e.g., the second position information) of a part (782) of the display area (e.g., including a part (780) of the display area and a part (781) of the display area) related to the third image (773), the display driving circuit (231) can identify the second position information according to a position of a blank region (714) (e.g., a blanking or low power period (BLLP)) within a vertical active part (712) of the vertical synchronization signal (710) (or a position of a data region (715) within a vertical active part (712) of the vertical synchronization signal (710) corresponding to the third image (773). For example, the display driving circuit (231) can identify the second position information by counting horizontal lines within the display area corresponding to the blank area (714).

[0095] As a non-limiting example, unlike the second location information recognized according to the blank area (714), the first location information used to perform the scan may not be recognized by the display driving circuit (231). Since the first location information, unlike the second location information, is unknown to the display driving circuit (231), at least one processor (210) may provide the first location information to the display driving circuit (231). The display driving circuit (231) may identify a second image (772) to be displayed on a portion (780) of the display area based on the first location information, through the data area (716) of the vertical active portion (712) of the vertical synchronization signal (710). The display driving circuit (231) can change a second part (774) of the first image on a part (780) of the display area to a second image (772), such as in state (750), by performing a scan on the second image (772) with respect to a part (780) of the display area based on the identification.

[0096] As a non-limiting example, when the first location information is identical to the second location information (or when the first part (771) of the first image does not exist), the display driving circuit (231) can perform a scan according to the identified second location information.

[0097] Referring to FIG. 8, at least one processor (210) and a display driving circuit (231) may operate for the video mode, the video hybrid mode, and / or the ARP.

[0098] The display panel (232) may have a horizontal direction (791) and a vertical direction (792). The display driving circuit (231) may sequentially perform scans in the horizontal direction (791) for display on the display area of ​​the display panel (232). The scans in the horizontal direction (791) may be sequentially performed in the vertical direction (792). For example, the display area of ​​the display panel (232) may include a first horizontal line and a second horizontal line extending in the horizontal direction (791), respectively. The first horizontal line and the second horizontal line may be arranged in the vertical direction (792). For example, the display driving circuit (231) may perform the scans sequentially performed in the vertical direction (792) by performing a scan in relation to the second horizontal line based on performing a scan in relation to the first horizontal line.

[0099] The display driving circuit (231) can perform a scan with respect to a portion of one horizontal line. The display driving circuit (231) can perform a scan with respect to a portion of one horizontal line and refrain from performing a scan with respect to another portion of the horizontal line. For example, the display driving circuit (231) can perform a scan (861) with respect to a portion of a horizontal line (865), which is one of the horizontal lines of the display area of ​​the display panel (232), perform a skip scan (862) with respect to another portion of the horizontal line (865), and perform a scan (863) with respect to a portion of a horizontal line (866), which is another horizontal line of the horizontal lines.

[0100] At least one processor (210) can generate a second image (872) to be displayed on a portion (880) of the display area while displaying a first image on the display area, such as in a state (800). At least one processor (210) can generate a third image (873) including a first portion (871) of the first image displayed on a portion (881) of the display area next to the portion (880) of the display area, and the second image (872). At least one processor (210) can transmit data including the third image (873) to the display driving circuit (231) via the interface (241). The transmission of the data can be a full line transmission.

[0101] The display driving circuit (231) can receive the data including the third image (873) from at least one processor (210) via the interface (241). A portion of the data including the third image (873) corresponding to the horizontal line (865) can be received via a horizontal synchronization signal (810). The horizontal synchronization signal (810) can include a horizontal front porch portion (811), a horizontal active portion (812), a horizontal back porch portion (813), and a blank portion (814). Since the time at which the part of the data including the third image (873) is received from at least one processor (210) according to the video mode, the video hybrid mode, and / or the ARP corresponds to a position (e.g., the second position information) of a part (882) of the display area (e.g., including a part (880) of the display area and a part (881) of the display area) related to the third image (873), the display driving circuit (231) can identify the second position information according to the position of the blank part (814) of the horizontal synchronization signal (810) (or the position of the horizontal active part (812) of the horizontal synchronization signal (810) corresponding to the third image (873). For example, the display driving circuit (231) can identify the second position information by counting a pixel clock according to the blank part (814).

[0102] As a non-limiting example, unlike the second position information recognized according to the blank portion (814), the first position information used to perform the scan may not be recognized by the display driving circuit (231). Since the first position information, unlike the second position information, is unknown to the display driving circuit (231), at least one processor (210) may provide the first position information to the display driving circuit (231). The display driving circuit (231) may identify a second image (872) to be displayed on a portion (880) of the display area through a data area (816) of a horizontal active portion (812) of a horizontal synchronization signal (810) based on the first position information. The display driving circuit (231) can change the second part (874) of the first image on the part (880) of the display area to the second image (872), such as in the state (850), by performing a scan on the second image (872) with respect to the part (880) of the display area based on the identification.

[0103] As a non-limiting example, when the first location information is identical to the second location information (or when the first part (871) of the first image does not exist), the display driving circuit (231) can perform a scan according to the identified second location information.

[0104] Referring to FIG. 9, at least one processor (210) and a display driving circuit (231) may operate for the video mode, the video hybrid mode, and / or the ARP.

[0105] The display panel (232) may have a horizontal direction (791) and a vertical direction (792). The display driving circuit (231) may sequentially perform scans in the horizontal direction (791) for display on the display area of ​​the display panel (232). The scans in the horizontal direction (791) may be sequentially performed in the vertical direction (792). For example, the display area of ​​the display panel (232) may include a first horizontal line and a second horizontal line extending in the horizontal direction (791), respectively. The first horizontal line and the second horizontal line may be arranged in the vertical direction (792). For example, the display driving circuit (231) may perform the scans sequentially performed in the vertical direction (792) by performing a scan in relation to the second horizontal line based on performing a scan in relation to the first horizontal line.

[0106] The display driving circuit (231) may perform a scan with respect to a portion of a horizontal line. The display driving circuit (231) may perform a scan with respect to a portion of a horizontal line and refrain from performing a scan with respect to another portion of the horizontal line.

[0107] At least one processor (210) may generate a second image (972) to be displayed on a portion (980) of the display area while displaying a first image on the display area, such as in a state (900). At least one processor (210) may generate a third image (973) including a first portion (971) of the first image displayed on a portion (981) of the display area next to the portion (980) of the display area, and the second image (972). At least one processor (210) may transmit data including the third image (973) to the display driving circuit (231) via the interface (241). The transmission of the data may be partial line transmission. The partial line transmission may be performed in a non-burst mode (or according to the non-burst mode). The above non-burst mode can be described as a mode in which pixel clock timing corresponds to horizontal position information.

[0108] The display driving circuit (231) can receive the data including the third image (973) from at least one processor (210) via the interface (241). A portion of the data including the third image (973) corresponding to the horizontal line (965) can be received via a horizontal synchronization signal (910). The horizontal synchronization signal (910) can include a horizontal front porch portion (911), a horizontal active portion (912), a horizontal back porch portion (913), and a blank portion (914). Since the time at which the part of the data including the third image (973) is received from at least one processor (210) according to the video mode, the video hybrid mode, and / or the ARP corresponds to a position (e.g., the second position information) of a part (982) of the display area (e.g., including a part (980) of the display area and a part (981) of the display area) related to the third image (973) according to the non-burst mode, the display driving circuit (231) can identify the second position information according to a position of a blank region (917) (e.g., a blanking or low power period (BLLP)) within a horizontal active part (912) of a horizontal synchronization signal (910) (or a position of a data region (915) within a horizontal active part (912) of a horizontal synchronization signal (910) corresponding to the third image (973). For example, the display driving circuit (231) can identify the second location information by counting pixel clocks according to the blank area (914).

[0109] As a non-limiting example, unlike the second location information recognized according to the blank area (914), the first location information used to perform the scan may not be recognized by the display driving circuit (231). Since the first location information, unlike the second location information, is unknown to the display driving circuit (231), at least one processor (210) may provide the first location information to the display driving circuit (231). The display driving circuit (231) may identify a second image (972) to be displayed on a portion (980) of the display area based on the first location information, through the data area (916) of the horizontal active portion (912) of the horizontal synchronization signal (910). The display driving circuit (231) can change a second part (974) of the first image on a part (980) of the display area to a second image (972), such as in state (950), by performing a scan on the second image (972) with respect to a part (980) of the display area based on the identification.

[0110] As a non-limiting example, when the first location information is identical to the second location information (or when the first part (971) of the first image does not exist), the display driving circuit (231) can perform a scan according to the identified second location information.

[0111] Referring to FIG. 10, at least one processor (210) and a display driving circuit (231) may operate for the video mode, the video hybrid mode, and / or the ARP.

[0112] The display panel (232) may have a horizontal direction (791) and a vertical direction (792). The display driving circuit (231) may sequentially perform scans in the horizontal direction (791) for display on the display area of ​​the display panel (232). The scans in the horizontal direction (791) may be sequentially performed in the vertical direction (792). For example, the display area of ​​the display panel (232) may include a first horizontal line and a second horizontal line extending in the horizontal direction (791), respectively. The first horizontal line and the second horizontal line may be arranged in the vertical direction (792). For example, the display driving circuit (231) may perform the scans sequentially performed in the vertical direction (792) by performing a scan in relation to the second horizontal line based on performing a scan in relation to the first horizontal line.

[0113] The display driving circuit (231) may perform a scan with respect to a portion of a horizontal line. The display driving circuit (231) may perform a scan with respect to a portion of a horizontal line and refrain from performing a scan with respect to another portion of the horizontal line.

[0114] At least one processor (210) may generate a second image (972) to be displayed on a portion (980) of the display area while displaying a first image on the display area, such as in a state (900). At least one processor (210) may generate a third image (973) including a first portion (971) of the first image displayed on a portion (981) of the display area next to the portion (980) of the display area, and the second image (972). At least one processor (210) may transmit data including the third image (973) to the display driving circuit (231) via the interface (241). The transmission of the data may be a partial line transmission. The partial line transmission may be performed within (or according to) a burst mode. The burst mode may be described as a mode in which pixel clock timing does not correspond to horizontal position information.

[0115] The display driving circuit (231) can receive the data including the third image (973) from at least one processor (210) via the interface (241). A portion of the data including the third image (973) corresponding to the horizontal line (965) can be received via a horizontal synchronization signal (910). The horizontal synchronization signal (910) can include a horizontal front porch portion (911), a horizontal active portion (912), a horizontal back porch portion (913), and a blank portion (914). Since the time at which the portion of the data including the third image (973) is received from at least one processor (210) according to the video mode, the video hybrid mode, and / or the ARP does not correspond to a position (e.g., the second position information) of a portion (982) of the display area (e.g., including a portion (980) of the display area and a portion (981) of the display area) related to the third image (973) according to the burst mode, the at least one processor (210) may transmit the second position information to the display driving circuit (231) before the horizontal synchronization signal (910). The second position information may be transmitted to indicate a position of the portion (980) of the display area corresponding to a data area (1015) within a horizontal active portion (912) of the horizontal synchronization signal (910).

[0116] The display driving circuit (231) can use the second position information to identify that the third image (973) acquired through the data area (1015) within the horizontal active portion (912) corresponds to a portion (982) of the display area.

[0117] At least one processor (210) can provide the first position information to the display driving circuit (231). The first position information can be transmitted (or provided) before the horizontal synchronization signal (910). The display driving circuit (231) can identify a second image (972) to be displayed on a portion (980) of the display area through a data region (1016) of a horizontal active portion (912) of the horizontal synchronization signal (910) based on the first position information. The display driving circuit (231) can change the second portion (974) of the first image on the portion (980) of the display area to the second image (972) by performing a scan for the second image (972) with respect to the portion (980) of the display area based on the identification, such as in the state (950).

[0118] As a non-limiting example, the display driving circuit (231) may be in a state for lower power consumption through the blank area (1017) of the horizontal active portion (912) of the horizontal synchronization signal (910) and / or the blank area (914) of the horizontal synchronization signal (910). Since the blank area (1017) and the blank area (914) of the horizontal synchronization signal (910) are continuous according to the burst mode, the display driving circuit (231) may reduce power consumption for display on the display panel (232) through the burst mode.

[0119] The operations described above can be executed within the electronic device (1101) of FIGS. 11 and 12.

[0142] FIG. 12 is a block diagram (1200) of a display module (1160) according to various embodiments. Referring to FIG. 12, the display module (1160) may include a display (1210) and a display driver IC (DDI) (1230) for controlling the display (1210). The DDI (1230) may include an interface module (1231), a memory (1233) (e.g., a buffer memory), an image processing module (1235), or a mapping module (1237). The DDI (1230) may receive, for example, image information including image data or an image control signal corresponding to a command for controlling the image data, from another component of the electronic device (1101) through the interface module (1231). For example, according to one embodiment, image information may be received from a processor (1120) (e.g., a main processor (1121) (e.g., an application processor) or an auxiliary processor (1123) (e.g., a graphics processing unit) that operates independently of the function of the main processor (1121). The DDI (1230) may communicate with a touch circuit (1250) or a sensor module (1176) through the interface module (1231). In addition, the DDI (1230) may store at least a part of the received image information in the memory (1233), for example, in units of frames. The image processing module (1235) may, for example, perform preprocessing or postprocessing (e.g., resolution, brightness, or size adjustment) on at least a part of the image data based on at least a characteristic of the image data or a characteristic of the display (1210). The mapping module (1237) may output a voltage value or a value corresponding to the image data preprocessed or postprocessed through the image processing module (1235). Current values ​​can be generated.According to one embodiment, the generation of voltage values ​​or current values ​​may be performed at least in part based on, for example, properties of pixels of the display (1210) (e.g., arrangement of pixels (RGB stripe or pentile structure), or size of each sub-pixel). At least some pixels of the display (1210) may be driven at least in part based on, for example, the voltage values ​​or current values, so that visual information (e.g., text, images, or icons) corresponding to the image data may be displayed through the display (1210).

[0143] According to one embodiment, the display module (1160) may further include a touch circuit (1250). The touch circuit (1250) may include a touch sensor (1251) and a touch sensor IC (1253) for controlling the touch sensor (1251). The touch sensor IC (1253) may control the touch sensor (1251) to detect, for example, a touch input or a hovering input for a specific location of the display (1210). For example, the touch sensor IC (1253) may detect the touch input or the hovering input by measuring a change in a signal (e.g., voltage, light quantity, resistance, or charge quantity) for a specific location of the display (1210). The touch sensor IC (1253) may provide information (e.g., location, area, pressure, or time) regarding the detected touch input or hovering input to the processor (1120). According to one embodiment, at least a portion of the touch circuit (1250) (e.g., touch sensor IC (1253)) may be included as part of the display driver IC (1230), or as part of the display (1210), or as part of another component (e.g., auxiliary processor (1123)) disposed external to the display module (1160).

[0144] According to one embodiment, the display module (1160) may further include at least one sensor (e.g., a fingerprint sensor, an iris sensor, a pressure sensor, or an illuminance sensor) of the sensor module (1176), or a control circuit therefor. In this case, the at least one sensor or the control circuit therefor may be embedded in a part of the display module (1160) (e.g., the display (1210) or the DDI (1230)) or a part of the touch circuit (1250). For example, when the sensor module (1176) embedded in the display module (1160) includes a biometric sensor (e.g., a fingerprint sensor), the biometric sensor may obtain biometric information (e.g., a fingerprint image) associated with a touch input through a part of the display (1210). For another example, if the sensor module (1176) embedded in the display module (1160) includes a pressure sensor, the pressure sensor may obtain pressure information associated with a touch input through a portion or the entire area of ​​the display (1210). According to one embodiment, the touch sensor (1251) or the sensor module (1176) may be disposed between pixels of a pixel layer of the display (1210), or above or below the pixel layer.

[0145] Some of the operations described above may be executed (or performed) by an AI (artificial intelligence) system as described with reference to FIG. 13.

[0146] Figure 13 is a schematic diagram of an exemplary AI system.

[0147] Referring to FIG. 13, the AI ​​system (1300) may include an input / output interface (1310), an AI (artificial intelligence) framework (1320), a generative AI model (1330), an application / service component (1380), and / or a knowledge repository (1390).

[0148] The input / output interface (1310) can receive input. The input can include user input and / or data acquired or generated by an electronic device (e.g., the electronic device (100) or the electronic device (1101) described above). The data can include images, videos, and / or sensor data generated by at least one processor (e.g., at least one processor (210) or processor (1120)) of the electronic device (e.g., illuminance data around the electronic device acquired from a sensor or sensor hub (e.g., a coprocessor (1123), posture data (or orientation data) of the electronic device, temperature inside the electronic device (e.g., temperature of the display (230) or temperature of the at least one processor (210)), size information of a display area of ​​the display (230), and / or images acquired through an image sensor (e.g., included in a camera module (1180)) of the electronic device). The user input may include natural language, touch data obtained through touch circuitry included within the display panel (232) (e.g., used to identify input from a finger and / or a stylus), images displayed (and / or to be displayed) on the display panel (232), and / or video. As a non-limiting example, the user input may be received by the input / output interface (1310) together with context information. The context information may be described as additional information obtained in connection with the user input. The context information may relate to a state when the user input is received (e.g., including a state of the electronic device and / or a state surrounding the electronic device (e.g., a user state)). For example, the context information may include information about one or more software applications running within the electronic device when the user input is received.For example, the contextual information may include information about the location of the electronic device (or the location of the user of the electronic device) at the time the user input is received. For example, the user input may be integrated with the contextual information. For example, the user input integrated with the contextual information may be received by the input / output interface (1310).

[0149] The input / output interface (1310) can transmit (or provide) output. The output may include a result (or result information) generated or acquired by the AI ​​system (1300) based at least in part on the input. The format of the output may vary. For example, the output may include natural language. For example, the output may include content (e.g., including media content and / or multimedia content). For example, the output may include an action related to a user of the electronic device. For example, the output may have a format according to a user setting of the electronic device.

[0150] The input / output interface (1310) can be described as a user query / response interface (1310).

[0151] The AI ​​framework (1320) can be used to obtain information (or data) about the input from the input / output interface (1310) and control one or more components related to the AI ​​system (1300) using the obtained information.

[0152] For example, the prompt design component (1321) within the AI ​​framework (1320) can use the acquired information to generate or obtain a prompt for a generative AI model (1330) (e.g., including a large language model (LLM) or a large multimodal model (LMM)). For example, the prompt design component (1321) can be described as an AI component that uses a learning algorithm and / or a neural network to provide enhanced prompts over time. For example, the prompt design component (1321) can use the acquired information to access a knowledge component (e.g., a knowledge repository (1390)) that includes user preference data, a prompt library, and / or prompt examples to generate or obtain a prompt. The generated prompt can be provided to the generative AI model (1330) (e.g., including an LLM or LMM).

[0153] For example, the API / plugin management component (1322) within the AI ​​framework (1320) may be utilized to support communication for additional information requested (or induced) in connection with the prompt provided (or to be provided) to the generative AI model (1330). For example, the API / plugin management component (1322) may be utilized to create or establish channels for communication with various data sources (e.g., knowledge repositories (1390)). For example, the API / plugin management component (1322) may support access to at least some of the data sources. For example, the API / plugin management component (1322) may be utilized to request another component (e.g., an application / service component (1380)) to perform feedback (or response) according to the prompt. As a non-limiting example, information obtained (or generated) through the API / plugin management component (1322) may be provided to the prompt design component (1321) for the purpose of generating a prompt. As a non-limiting example, information obtained (or generated) through the API / plugin management component (1322) may be provided to the generative AI model (1330).

[0154] For example, the improvement component (1323) within the AI ​​framework (1320) can at least partially tune (or adjust) (or change) the result (e.g., content) obtained (or output) from the generative AI model (1330). For example, the improvement component (1323) can determine or verify whether the content obtained from the generative AI model (1330) is related to the input. For example, the improvement component (1323) can determine or verify whether the content obtained from the generative AI model (1330) contains biased content. For example, the improvement component (1323) can determine or verify whether the content obtained from the generative AI model (1330) contains harmful content. For example, the improvement component (1323) can support or assist in performing additional processing to improve the content obtained from the generative AI model (1330). For example, the improvement component (1323) may support providing hints to the user to improve the content.

[0155] A generative AI model (1330) can be described as an artificial intelligence neural network that generates feedback in response to a prompt. For example, the feedback may include additional data and / or information related to the prompt, but relative to the prompt. For example, the feedback may include new content related to the prompt. For example, the generative AI model (1330) may include a model that generates images and / or a model that generates language. For example, the model that generates images may include a generative adversarial network (GAN) and / or a variational autoencoder (VAE). For example, the model that generates images may include a diffusion-based generative model (e.g., a transformer VAE). For example, the model that generates language may include CHAT-GPT 3 and / or CHAT-GPT 4. For example, a generative AI model (1330) may include an LMM that generates the feedback by recognizing text, images, and / or speech.

[0156] As a non-limiting example, the AI ​​framework (1320) and / or the generative AI model (1330) may be included within an AI module (e.g., including a processing circuit) within the electronic device. For example, the AI ​​module may be operatively coupled with at least one processor of the electronic device (e.g., at least one processor (210) or processor (1120)). For example, the AI ​​module may be operatively coupled with a display driving circuit of the electronic device (e.g., a display driving circuit (231) or a DDI (1230)). For example, the AI ​​module may be operatively coupled with a sensor hub of the electronic device for one or more sensors within the electronic device.
