[0001] The following descriptions relate to an electronic device, method, and non-transitory computer-readable storage medium for stopping scanning for multi-frequency driving of a display panel.

[0002] An electronic device may include a display. The display may be used to display an image. The display may include a display panel and a display driving circuit. The display driving circuit may be configured to display the image obtained from a processor of the electronic device on the display panel. For example, the display driving circuit may be configured to control a source driver (or data driver) and a gate driver (or scan driver) of the electronic device to display the image on the display panel. For example, the display driving circuit may scan the image to be displayed on the display panel.

[0003] The above information may be provided as background art to aid in understanding the present disclosure. No claim or determination is made as to whether any of the above is applicable as prior art related to the present disclosure.

[0004] An electronic device is described. The electronic device may include at least one processor including a processing circuit. The electronic device may include a display including a display driving circuit and a display panel. The display driving circuit may be configured to scan a first image to be displayed on an active area of ​​the display panel. The display driving circuit may be configured to stop scanning the first image and scan a second image to be displayed on the active area in response to a second image received from the at least one processor before scanning of the first image is completed, thereby providing a first refresh rate for a portion of the active area in which a portion of the scanned first image is displayed and a second refresh rate for a remaining portion of the active area differently from each other until the second image is received.

[0005] A method is described. The method can be executed in an electronic device having at least one processor, a display driving circuit, and a display panel. The method can include an operation in which the display driving circuit scans a first image to be displayed on an active area of ​​the display panel. The method can include an operation in which the display driving circuit provides a first refresh rate for a portion of the active area in which a portion of the scanned first image is displayed and a second refresh rate for a remaining portion of the active area differently from each other by stopping scanning the first image and scanning a second image to be displayed on the active area in response to a second image received from the at least one processor before scanning of the first image is completed, until the second image is received.

[0006] A non-transitory computer-readable storage medium is described. The non-transitory computer-readable storage medium may store one or more programs. The one or more programs may include instructions that, when executed by an electronic device having at least one processor, a display driving circuit, and a display panel, cause the display driving circuit to scan a first image to be displayed on an active area of ​​the display panel. The one or more programs may include instructions that, when executed by the electronic device, cause the display driving circuit to stop scanning the first image and scan a second image to be displayed on the active area in response to a second image received from the at least one processor before scanning of the first image is completed, thereby providing a first refresh rate for a portion of the active area in which a portion of the scanned first image is displayed and a second refresh rate for a remaining portion of the active area differently from each other until the second image is received.

[0007] FIG. 1 illustrates an example of multi-frequency driving in which a display on a first area of ​​an active area of ​​a display panel is executed at a first refresh rate while a display on a second area of ​​the active area is executed at a second refresh rate higher than the first refresh rate.

[0008] Figure 2 is a simplified block diagram of an exemplary electronic device.

[0010] FIG. 5 illustrates an exemplary method for controlling a signal for a first mode in response to a second image received from at least one processor while scanning a first image, to stop scanning the first image and scan the second image.

[0011] FIGS. 6 and 7 illustrate an exemplary method for controlling a signal for a second mode in response to a second image received from at least one processor while scanning a first image, to stop scanning the first image and scan the second image.

[0012] FIG. 8 illustrates an exemplary method of stopping transmission of a first image and executing transmission of a second image according to a third mode in response to receiving a second image from at least one processor while scanning a first image, to stop scanning the first image and scan the second image.

[0014] FIG. 10 is a block diagram of an electronic device within a network environment according to various embodiments.

[0015] FIG. 11 is a block diagram of a display module according to various embodiments.

[0016] FIG. 1 illustrates an example of multi-frequency driving in which display on a first portion of an active area of ​​a display panel is executed at a first refresh rate while display on a second portion of the active 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 an active area (110) that is viewable from a front side of the electronic device (100). For example, the active area (110) may define at least a portion of the front side of the electronic device (100). For example, the active area (110) may be usable for displaying a screen viewable from the front side of the electronic device (100). For example, the active area (110) may be used for displaying a screen (190).

[0018] For example, a screen (190) displayed on an active area (110) may include a first portion (191), a second portion (192), and a third portion (193). For example, 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. For example, the first portion (191) of the screen (190) may be displayed on a first part (111) of the active area (110). For example, the second portion (192) of the screen (190) can be displayed on the second portion (112) of the active area (110) while the first portion (191) of the screen (190) is displayed on the first portion (111) of the active area (110). For example, the third portion (193) of the screen (190) can be displayed on the third portion (113) of the active area (110) while the first portion (191) of the screen (190) is displayed on the first portion (111) of the active area (110) and the second portion (192) of the screen (190) is displayed on the second portion (112) of the active area (110).

[0019] For example, the first portion (191) of the screen (190) may be used to provide the status of the electronic device (100). For example, the first portion (191) of the screen (190) may be an indicator area. The second portion (192) of the screen (190) and the third portion (193) of the screen (190) may be used to provide a user interface (or execution screen) of a software application. For example, the second portion (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. For example, the third portion (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. For example, 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] For example, 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). For example, 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] For example, 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. For convenience of explanation, below, it is assumed that the first reproduction rate is the same as the third reproduction rate, but this is merely exemplary. The explanations below are also applicable when the first reproduction rate is different from the third reproduction rate.

[0023] For example, the electronic device (100) may display a first area (191) of the screen (190) and a third area (193) of the screen (190) at the first refresh rate while displaying a second area (192) of the screen (190) at the second refresh rate, while displaying a first portion (111) of the active area (110) at the first refresh rate. For example, driving (or controlling) (or causing) the display to display a second portion (112) of the active area (110) at the second refresh rate while displaying a first portion (111) of the active area (100) at the first refresh rate may be referred to as multiple 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. For example, 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). For example, at least one processor (210) may include a CPU (211) and a DPU (212). For example, the CPU (211) may be used to generate (or obtain) an image to be displayed on a display panel (232). For example, the DPU (212) can be used to transmit an image to be displayed on a display panel (232) to the display driving circuit (231).

[0027] As a non-limiting example, at least one processor (210) may be implemented as a system on chip (SoC). As a non-limiting example, at least one processor (210) may comprise a processor assembly. For example, at least one processor (210) may comprise at least a portion of the processor (1020) of FIG. 10 or may correspond to at least a portion of the processor (1020) of FIG. 10. As a non-limiting example, at least one processor (210) may include a main processor (1021) (e.g., comprising a processing circuit) and a secondary processor (1023) (e.g., comprising a processing circuit) (e.g., a tiny core of a central processing unit (CPU)).

[0028] 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).

[0029] 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).

[0030] For example, 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. For example, the one or more software applications may include instructions executable by at least one processor (210). For example, the memory (220) may store instructions callable by an application programming interface (API). For example, the memory (220) may store instructions within a library.

[0031] For example, the memory (220) may include at least a portion of the memory (1030) of FIG. 10 or correspond to at least a portion of the memory (1030) of FIG. 10.

[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. For example, the display (230) may include at least a portion of the display module (1060) of FIGS. 10 and 11 or may correspond to at least a portion of the display module (1060) of FIGS. 10 and 11. For example, the display (230) may include a display driver circuit (231) (e.g., including at least a portion of the display driver IC (1130) of FIG. 11 or corresponding to at least a portion of the display driver IC (1130) of FIG. 11) and a display panel (232) (e.g., including at least a portion of the display (1110) of FIG. 11 or corresponding to at least a portion of the display (1110) of FIG. 11).

[0033] The display driving circuit (231) may be a hardware component of the electronic device (100) that can be used to display a screen (or one or more images) on the display panel (232) (or on an active area (e.g., active area (110)) of the display panel (232). For example, 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 the one or more images) using the data. As a non-limiting example, the display driving circuit (231) may include a graphic random access memory (GRAM) for at least temporarily storing an image to be displayed on the active area of ​​the display panel (232). For example, the GRAM may be used for a first mode, which will be exemplified below. For example, the GRAM may be used for a second mode, which will be exemplified below.

[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 that electrically and / or physically connect a display driving circuit (231) to at least one processor (210).

[0036] For example, the one or more interfaces may include a first interface (241). The first 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 driving circuit (231). As a non-limiting example, the first interface (241) may include a mobile industry processor interface (MIPI). As a non-limiting example, the first interface (241) may be operated (or driven) according to a first mode (e.g., a command mode of MIPI DSI (display serial interface)), a second mode (e.g., a video hybrid mode of MIPI DSI), a third mode (e.g., a video mode of MIPI DSI), and / or a fourth mode (e.g., an adaptive refresh panel (ARP) of MIPI DSI).

[0037] For example, the one or more interfaces may include a second interface (242). The second interface (242) may be a hardware component of the electronic device (100) available for a signal (e.g., a synchronization signal) (e.g., a tearing effect signal (TE) and / or a refresh window (RW) signal (or RW)) transmitted from the display driving circuit (231) to at least one processor (210). As a non-limiting example, the second interface (242) may include a serial peripheral interface (SPI), a universal asynchronous receiver / transmitter (UART), an inter-integrated circuit (I2C), or an improved inter-integrated circuit (I3C).

[0038] For example, the display driving circuit (231) may be configured to perform a scan for display on a part of the active area (e.g., the active area (110)) of the display panel (232) within one time interval for display on the display panel (232) and to refrain from (or bypass) (or skip) the scan for display on another part of the active area. For example, since the display driving circuit (231) is configured to perform the scan for display on the part of the active area (e.g., the first part of the active area or the second part of the active area) and to refrain from (or bypass) (or skip) the scan for display on the other part of the active area (e.g., the second part of the active area or the first part of the active area), the display (230) may 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 active area and to refrain from scanning for display on the other part of the active area according to the multi-frequency driving, the display driving circuit (231) can perform display on the second part of the active area according to a refresh rate that is distinct from the refresh rate for display on the first part of the active area. For example, since the display driving circuit (231) is configured to stop scanning an image to be displayed on the display panel (232), the display driving circuit (231) can perform display on the second part of the active area according to a refresh rate that is distinct from the refresh rate for display on the first part of the active area.For example, the display driving circuit (231) may provide a first refresh rate of the first part of the active area of ​​the display panel (232) and a second refresh rate of the second part of the active area differently for the multi-frequency driving. For example, the display driving circuit (231) may stop scanning the first image and scan the second image in response to a second image received from at least one processor (210) (or DPU (212)) while scanning the first image, in order to provide the first refresh rate and the second refresh rate differently. This operation is exemplified in the description of FIG. 3.

[0039] FIGS. 3 and 4 illustrate an exemplary method of stopping scanning a first image and scanning a second image in response to a second image received from at least one processor while scanning a first image.

[0040] Referring to FIG. 3, the display driving circuit (231) can scan a first image to be displayed on the display panel (232). As a non-limiting example, the size of the first image can correspond to the size of the active area (310) of the display panel (232). For example, the display driving circuit (231) can scan the first image received from at least one processor (210) (or DPU (212)). For example, the display driving circuit (231) can scan the first image stored in the GRAM.

[0041] For example, at least one processor (210) (or CPU (211)) may generate (301) (or acquire (301)) a second image following the first image before scanning the first image is completed. For example, the CPU (211) may provide (or transmit) the second image to the DPU (212). For example, the DPU (212) may acquire (or receive) the second image from the CPU (211). For example, the CPU (211) may store the second image in a memory (220) (e.g., a dynamic random access memory (DRAM)), and the DPU (212) may acquire the second image from the memory (220). For example, the DPU (212) may execute (302) transmitting the second image to the display driving circuit (231) via the first interface (241) before scanning the first image is completed. As a non-limiting example, transmitting the second image (302) may be executed from a start time (or start timing) of an emission period included within a time period for scanning the first image. As a non-limiting example, the size of the second image may correspond to the size of the active area.

[0042] For example, the display driving circuit (231) can receive the second image from at least one processor (210) (or DPU (212)) before scanning the first image is completed. For example, the reception of the second image can be started before scanning the first image is completed. For example, the display driving circuit (231) can stop (or cancel) (or terminate) (or cease) scanning the first image and scan the second image in response to the second image being received from at least one processor (210) before scanning the first image is completed.

[0043] For example, the second image may be received after scanning of the first image has begun. For example, the second image may be received while a portion of the first image has been scanned as indicated by arrow (303) (or while a remaining portion of the first image has not been scanned). For example, the display driver circuit (231) may cancel, skip, omit, bypass, or refrain from scanning the remaining portion of the first image as indicated by arrow (304) by stopping scanning of the first image in response to the second image. For example, the remaining portion of the first image may not be scanned by the display driver circuit (231) upon reception of the second image, unlike the portion of the first image that is scanned by the display driver circuit (231) prior to reception of the second image. For example, the display on a part (311) of the active area (310) may be performed by scanning the part of the first image, but the display on the remaining part (312) of the active area (310) may be canceled, skipped, omitted, bypassed, or avoided by skipping scanning the remaining part of the first image.

[0044] For example, the display driving circuit (231) can scan the second image as indicated by arrow (305) based on canceling, skipping, omitting, bypassing, or refraining from scanning the remaining portion of the first image. For example, the display driving circuit (231) can perform display (e.g., display on a portion (311) of the active area (310)) from a first position (307) of the active area (310) to a second position (306) by scanning the portion of the first image as indicated by arrow (303), and then perform display (e.g., display on the active area (310)) from a position (307) of the active area (310) by scanning the second image as indicated by arrow (305). For example, a portion of the second image displayed on a portion (311) of the active area (310) may be changed from the portion of the first image by scanning the portion of the first image as indicated by arrow (303) and scanning the second image as indicated by arrow (305), but a remaining portion of the second image displayed on a remaining portion (312) of the active area (310) may be changed from a portion of the image that was displayed on the remaining portion (312) of the active area (310) before scanning the first image (e.g., when scanning the first image is performed for repeated display of the first image as exemplified in the description of FIG. 4 , the portion of the image may be the remaining portion of the first image).

[0045] For example, since a portion of the second image is changed from the portion of the first image and the remaining portion of the second image is changed from the portion of the image (e.g., when scanning the first image is performed for repeated display of the first image as exemplified in the description of FIG. 4, the portion of the image may be the remaining portion of the first image), the first refresh rate of the portion (311) of the active area (310) may be different from the second refresh rate of the remaining portion (312) of the active area (310). For example, the first refresh rate may be higher than the second refresh rate. For example, the display driving circuit (231) may provide different first refresh rates for a portion (311) of the active area (310) on which the portion of the scanned first image is displayed and the second refresh rate for a remaining portion (312) of the active area (310) by receiving the second image from at least one processor (210) before scanning of the first image is completed, by stopping scanning of the first image and scanning the second image until the second image is received. As a non-limiting example, scanning of the second image by bypassing scanning of the remaining portion of the first image by receiving the second image from at least one processor (210) while scanning the first image may be activated based on executing a specified (or predetermined) (or preset) (or predefined) function within the electronic device (100). For example, the specified function may include performing a display on the display panel (232) for higher responsiveness.

[0046] For example, the display driver circuit (231) may perform operations to reduce afterimages and / or flickering that occur on the display panel (232) due to a rapid change in the refresh rate and / or a refresh rate lower than a reference refresh rate. For example, the display driver circuit (231) may perform repeated displays on the display panel (232) to reduce the afterimages and / or the flickering. For example, the display driver circuit (231) may scan an image to perform the repeated displays. For example, scanning the image to perform the repeated displays may be determined by the display driver circuit (231) and / or determined by the DPU (212). Scanning the image to perform the repeated displays may be stopped (or canceled) in response to an image received from at least one processor (210) (or DPU (212)). Such operations are exemplified in the description of FIG. 4.

[0047] Referring to FIG. 4, at least one processor (210) (or DPU (212)) may execute (400) transmitting a first image via a first interface (241). For example, the display driving circuit (231) may scan the first image to be displayed on the active area (310), as indicated by an arrow (401). For example, when the first image is received from at least one processor (210) (or DPU (212)) according to the first mode, the display driving circuit (231) may store the first image received from the at least one processor (210) in the GRAM, and scan the first image stored in the GRAM. For example, if the first image is received while activating the GRAM according to the second mode, the display driving circuit (231) may scan the first image received from at least one processor (210) and store the first image received from at least one processor (210) in the GRAM. For example, if the first image is received while deactivating the GRAM according to the second mode, the display driving circuit (231) may refrain from (or bypass) scanning the first image received from at least one processor (210) and storing the first image received from at least one processor (210) in the GRAM. For example, if the first image is received according to the third mode or the fourth mode, the display driving circuit (231) may scan the first image received from at least one processor (210).For example, the display driving circuit (231) can display a portion of the first image on a portion (311) of the active area (310) and a remaining portion (312) of the active area (310) by scanning the first image as indicated by the arrow (401).

[0048] For example, the display driving circuit (231) may scan the first image to perform the repeated display of the first image. For example, the display driving circuit (231) may scan the first image to perform the repeated display of the first image before the second image is received from at least one processor (210) via the first interface (241). For example, the display driving circuit (231) may scan the first image to reduce the afterimage and / or the flicker. For example, the display driving circuit (231) may perform the repeated display of the first image by scanning the first image stored in the GRAM according to the first mode. For example, the display driving circuit (231) may perform the repeated display of the first image by scanning the first image stored in the GRAM activated according to the second mode. For example, the display driving circuit (231) can perform the repeated display of the first image by scanning the first image received from at least one processor (210) (or DPU (212)) according to the second mode while deactivating the GRAM. For example, the display driving circuit (231) can perform the repeated display of the first image by scanning the first image received from at least one processor (210) (or DPU (212)) according to the third mode. For example, the display driving circuit (231) can perform the repeated display of the first image by scanning the first image received from at least one processor (210) (or DPU (212)) in response to a request transmitted from the display driving circuit (231) to at least one processor (210) (or DPU (212)) according to the fourth mode.

[0049] For example, at least one processor (210) (or CPU (211)) may generate (301) (or acquire (301)) a second image that is changed from (or subsequent to) the first image before scanning the first image for the repeated display of the first image is completed. For example, the CPU (211) may provide (or transmit) the second image to the DPU (212). For example, the DPU (212) may acquire (or receive) the second image from the CPU (211). For example, the CPU (211) may store the second image in the memory (220) (e.g., the DRAM), and the DPU (212) may acquire the second image from the memory (220). For example, the DPU (212) may execute (302) transmitting the second image to the display driving circuit (231) via the first interface (241) before scanning the first image for the repeated display of the first image is completed. As a non-limiting example, transmitting the second image (302) may be executed from the start time (or start timing) of the light-emitting period included within the time period for scanning the first image.

[0050] For example, the display driving circuit (231) can receive the second image from at least one processor (210) (or DPU (212)) before scanning of the first image is completed (or before the repeated display of the first image is completed). For example, the reception of the second image can be started before scanning of the first image is completed. For example, the display driving circuit (231) can, in response to the second image received from at least one processor (210) before scanning of the first image is completed to perform the repeated display of the first image, stop (or cancel) scanning of the first image and scan the second image. For example, the display driving circuit (231) may, based on receiving the second image from at least one processor (210) (or DPU (212)) according to the first mode before scanning of the first image is completed to perform the repeated display of the first image, stop scanning the first image in the GRAM, store the second image received from the at least one processor (210) in the GRAM, and scan the second image stored in the GRAM according to a 2Ch command received together with the second image.For example, the display driving circuit (231) may stop scanning the first image in the GRAM and scan the second image received from the at least one processor (210) based on receiving the second image from the at least one processor (210) (or the DPU (212)) according to the second mode before scanning the first image stored in the GRAM according to the second mode is completed to perform the repeated display of the first image, and may scan the second image received from the at least one processor (210) according to a vertical synchronization signal (VSS) packet received together with the second image. For example, the second image received from the at least one processor (210) may or may not be stored in the GRAM depending on whether the GRAM is activated for the second image. For example, at least one processor (210) (or DPU (212)) may stop transmitting the first image to the display driving circuit (231) according to the second mode to perform the repeated display of the first image while deactivating the GRAM according to the second mode, and transmit the second image together with a VSS packet for displaying the second image to the display driving circuit (231) according to the second mode. For example, the display driving circuit (231) may stop scanning the first image and scan the second image based on the VSS packet. For example, at least one processor (210) (or DPU (212)) may stop transmitting the first image to the display driving circuit (231) according to the third mode to perform the repeated display of the first image, and transmit the second image together with a VSS packet for displaying the second image to the display driving circuit (231) according to the third mode.For example, the display driving circuit (231) may stop scanning the first image and scan the second image based on the VSS packet. For example, at least one processor (210) (or DPU (212)) may stop transmitting the first image to the display driving circuit (231) according to the fourth mode to perform the repeated display of the first image based on a request from the display driving circuit (231), and transmit the second image together with the VSS packet for displaying the second image to the display driving circuit (231) according to the fourth mode. For example, the display driving circuit (231) may stop scanning the first image and scan the second image based on the VSS packet.

[0051] For example, the second image may be received after scanning of the first image has begun. For example, the second image may be received while a portion of the first image has been scanned as indicated by arrow (303) (or while a remaining portion of the first image has not been scanned). For example, the display driver circuit (231) may cancel, skip, omit, bypass, or refrain from scanning the remaining portion of the first image as indicated by arrow (304) by stopping scanning of the first image in response to the second image. For example, the remaining portion of the first image may not be scanned by the display driver circuit (231) upon reception of the second image, unlike the portion of the first image that is scanned by the display driver circuit (231) prior to reception of the second image. For example, displaying on a portion (311) of the active area (310) may be performed by scanning the portion of the first image, but displaying on a remaining portion (312) of the active area (310) may be canceled, skipped, omitted, bypassed, or avoided by skipping scanning the remaining portion of the first image.

[0052] For example, the display driving circuit (231) can scan the second image as indicated by arrow (305) based on canceling, skipping, omitting, bypassing, or refraining from scanning the remaining portion of the first image. For example, the display driving circuit (231) can perform display on a portion (311) of the active area (310) by scanning the portion of the first image as indicated by arrow (303), and then perform display on the active area (310) by scanning the second image as indicated by arrow (305). For example, the portion of the second image displayed on a portion (311) of the active area (310) by scanning the second image as indicated by arrow (305) can be changed from the portion of the first image that is re-displayed on a portion (311) of the active area (310) by scanning the portion of the first image as indicated by arrow (303). For example, the remaining part of the second image displayed on the remaining part (312) of the active area (310) by scanning the second image as indicated by arrow (305) can be changed from the remaining part of the first image displayed by scanning the first image as indicated by arrow (401) by canceling scanning the remaining part of the first image as indicated by arrow (304).For example, the display driving circuit (231) can change the portion of the first image (311) that is re-displayed on a portion of the active area (310) (e.g., the portion of the first image re-displayed by scanning the first image, as indicated by arrow (303)) and the remaining portion of the first image (312) that is maintained on a remaining portion of the active area (310) (e.g., the remaining portion of the first image that is maintained after being displayed by scanning the first image, as indicated by arrow (401)) to the second image by stopping scanning the first image and scanning the second image. As a non-limiting example, since the second image is changed from the first image, canceling scanning the remaining portion of the first image, as indicated by arrow (304), may be unnoticeable to a user of the electronic device (100).

[0053] For example, the display driving circuit (231) may provide a first refresh rate of a portion (311) of the active area (310) and a second refresh rate of a remaining portion (312) of the active area (310) differently from each other by performing repeated display of a portion of the scanned first image on a portion (311) of the active area (310) in response to the reception of the second image by stopping scanning the first image and scanning the second image until the second image is received. For example, the first refresh rate may correspond to a time interval from a start time (411) of the repeated display of the portion of the first image to a start time (412) of the display of the second image, and the second refresh rate may correspond to a time interval from a start time (413) of the display of the remaining portion of the first image to a start time (414) of the display of the remaining portion of the second image. For example, the first reproduction rate may be higher than the second reproduction rate.

[0054] Referring back to FIG. 2, at least one processor (210) (or DPU (212)), the display driver circuit (231), and the first interface (241) can operate for the first mode. For example, the display driver circuit (231) can use a signal (e.g., a TE (tearing effect) signal) transmitted to the at least one processor (210) via the second interface (242) for the first mode to inform (or indicate) the time of image transmission (e.g., image transmission from the at least one processor (210) to the display driver circuit (231) executed via the first interface (241). For example, the display driver circuit (231) can change the state of the signal from the first state to the second state while scanning the image so that the image transmission can be executed while scanning the image in the GRAM. For example, the display driving circuit (231) may change the state of the signal from the first state to the second state while scanning the first image within the GRAM such that receiving the second image from at least one processor (210) is performed while scanning the first image within the GRAM for repeated display of the first image. This operation is exemplified in the description of FIG. 5.

[0055] FIG. 5 illustrates an exemplary method for controlling a signal for a first mode in response to a second image received from at least one processor while scanning a first image, to stop scanning the first image and scan the second image.

[0056] Referring to FIG. 5, the display driving circuit (231) can change the state of a signal (500) transmitted from the display driving circuit (231) to at least one processor (210) from a first state to a second state, such as a state (501), to indicate a start time (521) of a light-emitting period (550) capable of receiving an image from at least one processor (210) according to the first mode. As a non-limiting example, the time duration (or time length) (551) of the light-emitting period (550) can be 1 / 240 (s) (second).

[0057] At least one processor (210) (or DPU (212)) may execute (400) transmitting a first image to the display driving circuit (231) through the first interface (241) according to the first mode from a start time (521) based on the change from the first state such as state (501). For example, the display driving circuit (231) may store the first image received from the at least one processor (210) through the first interface (241) in the GRAM, and scan the first image stored in the GRAM as indicated by arrow (401). For example, by scanning the first image as indicated by arrow (401), the display driving circuit (231) may display the first image on the active area of ​​the display panel (232) as indicated by state (561).

[0058] For example, the state of the signal (500) can be changed from the second state to the first state. For example, the display driving circuit (231) can change the state of the signal (500) from the second state to the first state to indicate the start time (522) of the light-emitting period (550) following the start time (521).

[0059] For example, the display driving circuit (231) may change the state of the signal (500) from the first state to the second state, such as state (502-1), while scanning the first image as indicated by arrow (401) (or while displaying the first image as indicated by state (561)), in order to indicate the start time (522) of the light-emitting section (550) according to the first mode. For example, the change from the first state, such as state (502-1), to the second state may indicate the start time (522) within the time interval of scanning the first image (e.g., the time interval from the start time (521) to the start time (523)) as the start time of image transmission.

[0060] As a non-limiting example, since performing the display of the first image as in state (561) does not perform repeated display of the first image, the display driving circuit (231) may refrain from (or bypass) (or skip) (or omit) changing the state of the signal (500) from the first state to the second state as in state (502-2) while scanning the first image as in arrow (401).

[0061] For example, when the change from the first state to the second state, such as state (502-1), is performed, the display driving circuit (231) can change the state of the signal (500) from the second state to the first state to indicate the start time (523) of the light-emitting section (550) following the start time (522).

[0062] For example, the display driving circuit (231) can change the state of the signal (500) from the first state to the second state, such as state (503), to indicate the start time (523) of the light-emitting section (550) according to the first mode. For example, the change from the first state to the second state, such as state (503), can indicate the start time (523), which is the time of image transmission after completing scanning the first image, as indicated by arrow (401). For example, the state of the signal (500) can be changed from the second state to the first state to indicate the start time (524) of the light-emitting section (550) following the start time (523).

[0063] For example, the display driving circuit (231) can change the state of the signal (500) from the first state to the second state, such as state (504), to indicate the start time (524) of the light-emitting section (550). For example, the state of the signal (500) can be changed from the second state to the first state to indicate the start time (525) of the light-emitting section (550) following the start time (524).

[0064] For example, the display driver circuit (231) can identify that the image transmission from the start time (524) indicated by the change from the first state such as state (504) to the second state is not performed. For example, the display driver circuit (231) can scan the first image in the GRAM from the start time (524) to perform repeated display of the first image on the active area based on the identification. For example, scanning the first image in the GRAM from the start time (524) can be performed from the start time (524) while the first image indicated such as state (561) is maintained on the active area. For example, the repeated display of the first image can be performed from the start time (524) by scanning the first image in the GRAM.

[0065] For example, the display driving circuit (231) may change the state of the signal (500) from the first state to the second state, such as state (505), while scanning the first image (or while performing the repeated display of the first image), to indicate a start time (525) of the light-emitting section (550). For example, the change from the first state to the second state, such as state (505), may indicate a start time (525) within a time interval of scanning the first image (e.g., a time interval from start time (524) to start time (526)) as a start time of image transmission.

[0066] For example, at least one processor (210) may generate (301) (or acquire (301)) a second image to be changed from (or subsequent to) the first image before scanning the first image for the repeated display of the first image is completed. For example, at least one processor (210) may transmit (302) the second image to the display driving circuit (231) via the first interface (241) according to the first mode from a start time (525) based on the change from the first state, such as state (505), to the second state. For example, transmitting (302) the second image from a start time (525) may be executed before scanning the first image from a start time (524) is completed. For example, the display driving circuit (231) may receive the second image from at least one processor (210) before scanning of the first image is completed from a start time (524). For example, the second image may be received while a portion of the first image has been scanned as indicated by arrow (303) (or while a remaining portion of the first image has not been scanned). For example, the display driving circuit (231) may cancel, skip, omit, bypass, or refrain from scanning the remaining portion of the first image as indicated by arrow (304) by stopping scanning of the first image in response to the second image received from a start time (525). For example, the remaining portion of the first image may not be scanned by the display driving circuit (231) upon the reception of the second image, unlike the portion of the first image that was scanned by the display driving circuit (231) prior to the reception of the second image.For example, displaying the part of the first image, such as in state (562), is performed by scanning the part of the first image, but displaying the remaining part of the first image may be canceled, skipped, omitted, bypassed, or avoided by skipping scanning the remaining part of the first image.

[0067] For example, the display driving circuit (231) can store the second image received from the start time (525) in the GRAM based on skipping scanning the remaining portion of the first image, and scan the second image stored in the GRAM as indicated by arrow (305). For example, the display driving circuit (231) can display the second image on the active area as indicated by state (563) by scanning the second image as indicated by arrow (305).

[0068] For example, the state of the signal (500) can be changed from the second state to the first state. For example, the display driving circuit (231) can change the state of the signal (500) from the second state to the first state to indicate the start time (526) of the light-emitting period (550) following the start time (525).

[0069] For example, the display driving circuit (231) may change the state of the signal (500) from the first state to the second state, such as state (506-1), while scanning the second image, such as arrow (305) (or while performing display of the second image, such as state (563)), to indicate the start time (526) of the light-emitting section (550) according to the first mode. For example, the change from the first state, such as state (506-1), to the second state may indicate the start time (526) within the time interval of scanning the second image (e.g., the time interval from start time (525) to start time (527)) as the start time of image transmission.

[0070] As a non-limiting example, since performing the display of the second image as in state (563) does not perform repeated display of the second image, the display driving circuit (231) may refrain from (or bypass) (or skip) (or omit) changing the state of the signal (500) from the first state to the second state as in state (506-2) while scanning the second image as in arrow (305).

[0071] For example, when the change from the first state to the second state, such as state (506-1), is performed, the display driving circuit (231) can change the state of the signal (500) from the second state to the first state to indicate the start time (527) of the light-emitting section (550) following the start time (526).

[0072] For example, the display driving circuit (231) can change the state of the signal (500) from the first state to the second state, such as state (507), to indicate the start time (527) of the light-emitting section (550) according to the first mode. For example, the state of the signal (500) can be changed from the second state to the first state to indicate the start time (not shown) of the light-emitting section (550) following the start time (527).

[0073] As described above, the electronic device (100) can support multi-frequency driving of the display (230) by controlling the signal (500) for the second image that can be received while scanning the first image.

[0074] Referring back to FIG. 2, at least one processor (210) (or DPU (212)), the display driver circuit (231), and the first interface (241) may operate for the second mode. For example, the display driver circuit (231) may use a signal (e.g., a RW signal or RW) transmitted to the at least one processor (210) via the second interface (242) for the second mode to inform (or indicate) whether image transmission from the at least one processor (210) running via the first interface (241) to the display driver circuit (231) is activated. For example, the display driver circuit (231) may change the state of the signal so that the image transmission may be executed while scanning an image stored in the GRAM that is activated according to the second mode. For example, the display driving circuit (231) can change the state of the signal such that receiving a second image from at least one processor (210) is performed while scanning the first image in the GRAM for repeated display of the first image. For example, the at least one processor (210) can recognize that the image transmission is activated based on identifying (or monitoring) (or recognizing) that the state of the signal is changing from the first state to the second state. For example, the at least one processor (210) can recognize that the image transmission is activated based on identifying the signal in the second state among the first state and the second state. Operations performed while the GRAM is activated according to the second mode are exemplified in the descriptions of FIGS. 6 and 7.

[0075] FIGS. 6 and 7 illustrate an exemplary method for controlling a signal for a second mode in response to a second image received from at least one processor while scanning a first image, to stop scanning the first image and scan the second image.

[0076] Referring to FIG. 6, the display driving circuit (231) may change the state of a signal (600) transmitted from the display driving circuit (231) to at least one processor (210) from a first state to a second state, such as a state (601), to indicate that image transmission from a start time (621) of a light-emitting section (550) capable of receiving an image from at least one processor (210) according to the second mode is activated. As a non-limiting example, the time length (551) of the light-emitting section (550) may be 1 / 240 (s).

[0077] At least one processor (210) (or DPU (212)) can identify whether the state of the signal (600) changes from the first state to the second state within a time interval (631) from time (641) to time (642) to identify whether the image transmission from the start time (621) is activated. For example, the time (641) may be a time prior to a reference time interval (619) from the start time (620) of the light-emitting section (550) prior to the start time (621), and the time (642) may be a time prior to the reference time interval (619) from the start time (621). For example, at least one processor (210) can identify that the image transmission from the start time (621) is activated based on identifying the change from the first state, such as state (601), to the second state within a time interval (631). For example, at least one processor (210) can execute (400) transmitting the first image to the display driver circuit (231) via the first interface (241) according to the second mode, based on identifying the change from the first state, such as state (601), to the second state within a time interval (631). For example, the display driver circuit (231) can display the first image on the active area of ​​the display panel (232) as in the state (661) by scanning the first image received from the at least one processor (210) via the first interface (241) as in the arrow (401). For example, the display driving circuit (231) can store the first image received from at least one processor (210) through the first interface (241) in the GRAM according to the second mode.

[0078] For example, the state of the signal (600) can be changed from the second state to the first state. For example, the display driving circuit (231) can change the state of the signal (600) from the second state to the first state to indicate whether image transmission from the start time (622) of the light-emitting section (550) following the start time (621) is activated.

[0079] For example, the display driving circuit (231) may change the state of the signal (600) from the first state to the second state, such as state (602-1), while scanning the first image, as indicated by arrow (401), to indicate that image transmission is activated from a start time (622) of a light-emitting period (550) capable of receiving an image from at least one processor (210) according to the second mode. For example, the change from the first state, such as state (602-1), to the second state may indicate that image transmission is activated while scanning the first image, as indicated by arrow (401).

[0080] As a non-limiting example, since performing the display of the first image as in state (661) does not perform repeated display of the first image, the display driving circuit (231) may refrain from (or bypass) (or skip) (or omit) changing the state of the signal (600) from the first state to the second state as in state (602-2) while scanning the first image as in arrow (401).

[0081] For example, at least one processor (210) (or DPU (212)) can identify whether the state of the signal (600) changes from the first state to the second state within a time interval (632) from time (642) to time (643) to identify whether the image transmission from the start time (622) is activated. For example, the time (643) can be a time prior to the reference time interval (619) from the start time (622). For example, at least one processor (210) can identify that the image transmission from the start time (622) is activated based on identifying the change from the first state, such as state (602-1), to the second state within the time interval (632). For example, at least one processor (210) may identify that the image transmission from the start time (622) is activated, but at least one processor (210) may not execute the image transmission from the start time (622) while scanning the first image, such as arrow (401). For another example, if the display driver circuit (231) maintains the state of the signal (600) in the first state, such as state (602-2), at least one processor (210) may identify that the image transmission from the start time (622) is deactivated based on not identifying the change from the first state to the second state within the time interval (632). For example, at least one processor (210) may not execute the image transmission from the start time (622) while scanning the first image, as indicated by arrow (401), based on identifying that the image transmission from the start time (622) is disabled.

[0082] For example, when the change from the first state to the second state, such as state (602-1), is performed, the display driving circuit (231) can change the state of the signal (600) from the second state to the first state to indicate whether image transmission from the start time (623) of the light-emitting section (550) following the start time (622) is activated.

[0083] For example, the display driving circuit (231) may change the state of the signal (600) from the first state to the second state, such as state (603), to indicate that image transmission is activated from the start time (623) of the light-emitting period (550) capable of receiving an image from at least one processor (210) according to the second mode. For example, the change from the first state to the second state, such as state (603), may indicate that image transmission is activated after completing scanning the first image, such as arrow (401).

[0084] For example, at least one processor (210) (or DPU (212)) can identify whether the state of the signal (600) changes from the first state to the second state within a time interval (633) from time (643) to time (644) to identify whether the image transmission from the start time (623) is activated. For example, the time (644) can be a time prior to the reference time interval (619) from the start time (623). For example, at least one processor (210) can identify that the image transmission from the start time (623) is activated based on identifying the change from the first state, such as state (603), to the second state within the time interval (633). For example, at least one processor (210) may identify that the image transmission from the start time (623) is activated, but at least one processor (210) may not execute the image transmission from the start time (623) after scanning the first image is completed, as indicated by arrow (401).

[0085] For example, the state of the signal (600) can be changed from the second state to the first state to indicate whether image transmission from the start time (624) of the light-emitting period (550) following the start time (623) is activated.

[0086] For example, the display driving circuit (231) can change the state of the signal (600) from the first state to the second state, such as state (604), to indicate that image transmission from the start time (624) of the light-emitting section (550) that can receive images from at least one processor (210) according to the second mode is activated. For example, the state of the signal (600) can change from the second state to the first state to indicate whether image transmission from the start time (625) of the light-emitting section (550) following the start time (624) is activated.

[0087] For example, at least one processor (210) (or DPU (212)) can identify whether the state of the signal (600) changes from the first state to the second state within a time interval (634) from time (644) to time (645) to identify whether the image transmission from the start time (624) is activated. For example, the time (645) can be a time prior to the reference time interval (619) from the start time (624). For example, at least one processor (210) can identify that the image transmission from the start time (624) is activated based on identifying the change from the first state, such as state (604), to the second state within the time interval (634). For example, at least one processor (210) may identify that the image transmission from the start time (624) is activated, but at least one processor (210) may not execute the image transmission from the start time (624).

[0088] For example, the display driving circuit (231) can identify that image transmission from the start time (624) is not performed. For example, the display driving circuit (231) can scan the first image in the GRAM from the start time (624) based on the identification to perform repeated display of the first image on the active area. For example, scanning the first image in the GRAM from the start time (624) can be performed from the start time (624) while the first image displayed as in the state (661) is maintained on the active area. For example, the repeated display of the first image can be performed from the start time (624) by scanning the first image in the GRAM.

[0089] For example, the display driving circuit (231) may change the state of the signal (600) from the first state to the second state, such as state (605), while scanning the first image (or while performing the repeated display of the first image) to indicate that image transmission from the start time (625) of the light-emitting section (550) is activated. For example, the change from the first state to the second state, such as state (605), may indicate that image transmission is activated while scanning the first image to perform the repeated display of the first image. For example, the state of the signal (600) may change from the second state to the first state to indicate whether image transmission from the start time (626) of the light-emitting section (550) following the start time (625) is activated.

[0090] For example, at least one processor (210) (or CPU (211)) can generate (301) (or acquire (301)) a second image to be changed from (or subsequent to) the first image before scanning the first image for the repeated display of the first image is completed. For example, at least one processor (210) (or DPU (212)) can identify whether the state of the signal (600) changes from the first state to the second state within a time interval (635) from a time (645) to a time (646) to identify whether transmitting the second image to the display driving circuit (231) via the first interface (241) from a start time (625) is activated. For example, the time (646) can be a time prior to the reference time interval (619) from the start time (625). For example, at least one processor (210) can identify that the image transmission from the start time (625) is activated based on identifying the change from the first state, such as state (605), to the second state within a time interval (635). For example, at least one processor (210) can execute transmitting (302) the second image to the display driving circuit (231) via the first interface (241) according to the second mode from the start time (625) based on identifying that the image transmission from the start time (625) is activated. For example, transmitting (302) the second image from the start time (625) can be executed before scanning of the first image from the start time (624) is completed. For example, the display driving circuit (231) can receive the second image from at least one processor (210) before scanning of the first image is completed from the start time (624).For example, the second image may be received while a portion of the first image has been scanned as indicated by arrow (303) (or while a remaining portion of the first image has not been scanned). For example, the display driver circuit (231) may cancel, skip, omit, bypass, or refrain from scanning the remaining portion of the first image as indicated by arrow (304) by stopping scanning the first image in response to the second image received from the start time (625). For example, the remaining portion of the first image may not be scanned by the display driver circuit (231) upon the reception of the second image, unlike the portion of the first image that was scanned by the display driver circuit (231) prior to the reception of the second image. For example, displaying the part of the first image, such as state (662), is performed by scanning the part of the first image, but displaying the remaining part of the first image may be canceled, skipped, omitted, bypassed, or avoided by skipping scanning the remaining part of the first image.

[0091] For example, the display driving circuit (231) may display the second image on the active area, such as in state (663), by scanning the second image received from the start time (625) as indicated by arrow (305), based on skipping scanning the remaining portion of the first image. For example, the display driving circuit (231) may or may not store the second image in the GRAM, depending on the type of command (not shown) received from at least one processor (210).

[0092] For example, the display driving circuit (231) may change the state of the signal (600) from the first state to the second state, such as state (606-1), while scanning the second image, as indicated by arrow (305), to indicate that image transmission is activated from a start time (626) of a light-emitting period (550) capable of receiving an image from at least one processor (210) according to the second mode. For example, the change from the first state, such as state (606-1), to the second state may indicate that image transmission is activated while scanning the second image, as indicated by arrow (305).

[0093] As a non-limiting example, since performing the display of the second image as in state (663) does not perform repeated display of the second image, the display driving circuit (231) may refrain from (or bypass) (or skip) (or omit) changing the state of the signal (600) from the first state to the second state as in state (606-2) while scanning the second image as in arrow (305).

[0094] For example, at least one processor (210) (or DPU (212)) can identify whether the state of the signal (600) changes from the first state to the second state within a time interval (636) from time (646) to time (647) to identify whether the image transmission from the start time (626) is activated. For example, the time (647) can be a time prior to the reference time interval (619) from the start time (626). For example, at least one processor (210) can identify that the image transmission from the start time (626) is activated based on identifying the change from the first state, such as state (606-1), to the second state within the time interval (636). For example, at least one processor (210) may identify that the image transmission from start time (626) is activated, but at least one processor (210) may not execute the image transmission from start time (626) while scanning the second image, such as arrow (305). For another example, if the display driver circuit (231) maintains the state of the signal (600) in the first state, such as state (606-2), at least one processor (210) may identify that the image transmission from start time (626) is deactivated based on not identifying the change from the first state to the second state within the time interval (636). For example, at least one processor (210) may not execute the image transmission from the start time (626) while scanning the second image, as indicated by arrow (305), based on identifying that the image transmission from the start time (626) is disabled.

[0095] For example, when the change from the first state to the second state, such as state (606-1), is performed, the display driving circuit (231) can change the state of the signal (600) from the second state to the first state to indicate whether image transmission from the start time (627) of the light-emitting section (550) following the start time (626) is activated.

[0096] For example, the display driving circuit (231) may change the state of the signal (600) from the first state to the second state, such as state (607), to indicate that image transmission is activated from the start time (627) of the light-emitting period (550) capable of receiving an image from at least one processor (210) according to the second mode. For example, the change from the first state, such as state (607), to the second state may indicate that image transmission is activated after completing scanning the second image, such as arrow (305).

[0097] For example, at least one processor (210) (or DPU (212)) can identify whether the state of the signal (600) changes from the first state to the second state within a time interval (637) from time (647) to time (648) to identify whether image transmission from the start time (627) is activated. For example, the time (648) can be a time prior to the reference time interval (619) from the start time (627). For example, at least one processor (210) can identify that the image transmission from the start time (627) is activated based on identifying the change from the first state, such as state (607), to the second state within the time interval (637).

[0098] As described above, the electronic device (100) can support multi-frequency driving of the display (230) by controlling the signal (600) for the second image that can be received while scanning the first image.

[0099] Referring to FIG. 7, at least one processor (210) (or DPU (212)) can identify whether a signal (600) is in the first state or the second state to determine whether image transmission can be performed according to the second mode, from the start time (721) of the light-emitting period (550), to the display driving circuit (231) via the first interface (241). As a non-limiting example, the time length (551) of the light-emitting period (550) can be 1 / 240 (s). For example, at least one processor (210) can, based on identifying the signal (600) in the second state, perform the transmission (400) of the first image to the display driving circuit (231) from the start time (721) according to the second mode, via the first interface (241).

[0100] For example, the display driving circuit (231) can change the state of the signal (600) from the second state to the first state in response to the first image received from the start time (721). For example, the display driving circuit (231) can display the first image on the active area of ​​the display panel (232) as in the state (761) by scanning the first image received from at least one processor (210) through the first interface (241) as indicated by arrow (401). For example, the display driving circuit (231) can store the first image received from at least one processor (210) through the first interface (241) in the GRAM according to the second mode. For example, the display driving circuit (231) can change the state of the signal (600) from the first state to the second state in response to completing scanning the first image as indicated by arrow (401). For example, the display driving circuit (231) can change the state of the signal (600) from the first state to the second state at the end time (751) of the active portion of the vertical synchronization signal for the first image. For example, the end time (751) may be before the time (743) exemplified below.

[0101] For example, at least one processor (210) (or DPU (212)) can identify whether a time interval (732) from time (742) to time (743) includes a time interval during which the signal (600) is within the second state to identify whether image transmission from a start time (723) of the light-emitting period (550) is activated. For example, time (742) can be a time prior to a reference time interval (719) (e.g., corresponding to the reference time interval (619)) from the start time (722) of the light-emitting period (550), and time (743) can be a time prior to the reference time interval (719) from the start time (723) of the light-emitting period (550). For example, at least one processor (210) can identify that the image transmission from the start time (723) is activated based on identifying that the time interval (732) includes the time interval during which the signal (600) is within the second state. For example, at least one processor (210) can identify that the image transmission from the start time (723) is activated, but at least one processor (210) can not execute the image transmission from the start time (723).

[0102] For example, at least one processor (210) (or DPU (212)) can identify whether a time interval (733) from time (743) to time (744) includes a time interval during which the signal (600) is within the second state to identify whether image transmission from the start time (724) of the light-emitting period (550) is activated. For example, the time (744) can be a time prior to the reference time interval (719) from the start time (724). For example, at least one processor (210) can identify that the image transmission from the start time (724) is activated based on identifying that the time interval (733) includes the time interval during which the signal (600) is within the second state. For example, at least one processor (210) may identify that the image transmission from the start time (724) is activated, but at least one processor (210) may not execute the image transmission from the start time (724).

[0103] For example, the display driving circuit (231) can identify that image transmission from the start time (724) is not performed. For example, the display driving circuit (231) can scan the first image in the GRAM from the start time (724) based on the identification to perform repeated display of the first image on the active area. For example, scanning the first image in the GRAM from the start time (724) can be performed from the start time (724) while the first image displayed as in the state (761) is maintained on the active area. For example, the repeated display of the first image can be performed from the start time (724) by scanning the first image in the GRAM.

[0104] For example, the display driving circuit (231) may maintain the state of the signal (600) in the second state while scanning the first image in the GRAM to perform the repeated display of the first image. For example, maintaining the state of the signal (600) in the second state may be performed to activate image transmission from the start time (725) of the light-emitting period (550). For example, the display driving circuit (231) may maintain the state of the signal (600) in the second state for multi-frequency driving of the display (230).

[0105] For example, at least one processor (210) (or CPU (211)) can generate (301) (or acquire (301)) a second image to be changed from (or subsequent to) the first image before scanning the first image for the repeated display of the first image is completed. For example, at least one processor (210) (or DPU (212)) can identify whether a time interval (734) from time (744) to time (745) includes the time interval during which the signal (600) is in the second state to identify whether transmitting the second image to the display driving circuit (231) via the first interface (241) from the start time (725) is activated. For example, time (745) can be a time prior to the reference time interval (719) from the start time (725). For example, at least one processor (210) can identify that the image transmission from the start time (725) is activated based on identifying that the time interval (734) includes the time interval during which the signal (600) is within the second state. For example, at least one processor (210) can execute transmitting (302) the second image to the display drive circuit (231) via the first interface (241) according to the second mode from the start time (725) based on identifying that the image transmission from the start time (725) is activated. For example, transmitting (302) the second image from the start time (725) can be executed before scanning of the first image from the start time (724) is completed. For example, the display driving circuit (231) can receive the second image from at least one processor (210) before scanning of the first image is completed from the start time (724).For example, the second image may be received while a portion of the first image has been scanned as indicated by arrow (303) (or while a remaining portion of the first image has not been scanned). For example, the display driver circuit (231) may cancel, skip, omit, bypass, or refrain from scanning the remaining portion of the first image as indicated by arrow (304) by stopping scanning the first image in response to the second image received from the start time (725). For example, the remaining portion of the first image may not be scanned by the display driver circuit (231) upon the reception of the second image, unlike the portion of the first image that was scanned by the display driver circuit (231) prior to the reception of the second image. For example, displaying the part of the first image, such as in state (762), is performed by scanning the part of the first image, but displaying the remaining part of the first image may be canceled, skipped, omitted, bypassed, or avoided by skipping scanning the remaining part of the first image.

[0106] For example, the display driving circuit (231) may display the second image on the active area, such as in state (763), by scanning the second image received from the start time (725) as indicated by arrow (305), based on skipping scanning the remaining portion of the first image. For example, the display driving circuit (231) may or may not store the second image in the GRAM, depending on the type of command (not shown) received from at least one processor (210).

[0107] For example, the display driving circuit (231) can change the state of the signal (600) from the second state to the first state in response to the second image received from the start time (725). For example, the display driving circuit (231) can change the state of the signal (600) from the second state to the first state to disable image transmission from at least one processor (210) to the display driving circuit (231) while scanning the second image, as indicated by arrow (305).

[0108] For example, the display driver circuit (231) can change the state of the signal (600) from the first state to the second state in response to completing scanning the second image as indicated by arrow (305). For example, the display driver circuit (231) can change the state of the signal (600) from the first state to the second state at an end time (752) of the active portion of the vertical synchronization signal for the second image. For example, the end time (752) can be before a time (747) that is before a reference time interval (719) from a start time (727) of the light-emitting period (550). For example, because the end time (752) is before time (747), the end time (752) can be included within the time interval (736) from time (746) to time (747). For example, the time (746) may be prior to a reference time interval from the start time (726) of the light-emitting section (550). For example, since the end time (752) is included within the time interval (736), at least one processor (210) may identify that image transmission from the start time (727) is activated. For example, at least one processor (210) may, when generating an image to be changed from the second image, transmit the image to be changed from the second image to the display driving circuit (231) through the first interface (241) according to the second mode from the start time (727) based on the identification.

[0109] As described above, the electronic device (100) can support multi-frequency driving of the display (230) by controlling the signal (600) for the second image that can be received while scanning the first image.

[0110] Referring back to FIG. 2, at least one processor (210) (or DPU (212)), display driver circuit (231), and first interface (241) may operate for the third mode or for the second mode within the state in which the GRAM is disabled. For example, the DPU (212) may, in response to an image acquired from the CPU (211) during image transmission from the DPU (212) to the display driver circuit (231) executed via the first interface (241), stop the image transmission for the third mode or the second mode within the state in which the GRAM is disabled. This operation is exemplified in the description of FIG. 8.

[0111] FIG. 8 illustrates an exemplary method of stopping transmission of a first image and executing transmission of a second image according to a third mode in response to receiving a second image from at least one processor while scanning a first image, to stop scanning the first image and scan the second image.

[0112] Referring to FIG. 8, the DPU (212) may transmit (400) the first image acquired from the CPU (211) to the display driving circuit (231) through the first interface (241), according to the third mode, from the start time (821) of the light-emitting section (550). As a non-limiting example, the time length (551) of the light-emitting section (550) may be 1 / 240 (s). The display driving circuit (231) may display the first image on the active area of ​​the display panel (232) as in the state (861) by scanning the first image received from the DPU (212) as indicated by the arrow (401).

[0113] For example, the DPU (212) may transmit (800) the first image obtained from the memory (220) (e.g., the DRAM)) to the display driving circuit (231) through the first interface (241), starting from the start time (822) of the light-emitting section (550), according to the third mode. For example, the DPU (212) may transmit (800) the first image to perform repeated display of the first image on the active area. The display driving circuit (231) may scan the first image received again from the DPU (212).

[0114] For example, the CPU (211) may generate (301) (or acquire (301)) a second image to be changed from (or subsequent to) the first image before scanning the first image for the repeated display of the first image is completed. For example, the CPU (211) may request the DPU (212) to transmit the second image to the display driving circuit (231) using a program stored in the memory (220). As a non-limiting example, the program may include a program included in a hardware abstraction layer (HAL) for controlling the display (230). As a non-limiting example, the program may include instructions executable by the CPU (211). For example, the DPU (212) can control the display driving circuit (231) to stop scanning the first image and scan the second image by executing (302) from the start time (823) of the light-emitting section (550) the step of stopping transmitting the first image in response to the request from the CPU (211) and transmitting the second image to the display driving circuit (231) through the first interface (241) according to the third mode. For example, the second image can be received in a state in which a portion of the first image has been scanned as indicated by arrow (303) (or a state in which a remaining portion of the first image has not been scanned). For example, the display driving circuit (231) can cancel, skip, omit, bypass, or refrain from scanning the remaining portion of the first image as indicated by arrow (304) by stopping scanning the first image in response to the second image received from the start time (823).For example, the remaining portion of the first image may not be scanned by the display driving circuit (231) upon reception of the second image, unlike the portion of the first image that is scanned by the display driving circuit (231) prior to reception of the second image. For example, displaying the portion of the first image, such as in state (862), is performed by scanning the portion of the first image, but displaying the remaining portion of the first image may be canceled, skipped, omitted, bypassed, or avoided by skipping scanning the remaining portion of the first image.

[0115] For example, the display driving circuit (231) can display the second image on the active area as in state (863) by scanning the second image received after the portion of the first image is received as indicated by arrow (305).

[0116] As described above, the electronic device (100) can support multi-frequency driving of the display (230) by using the DPU (212) to stop transmitting the first image and transmit the second image according to a request from the CPU (211) obtained while transmitting the first image.

[0117] Referring again to FIG. 2, at least one processor (210) (or DPU (212)), the display driver circuit (231), and the first interface (241) may operate for the fourth mode. For example, the DPU (212) may, in response to a request from the display driver circuit (231), stop transmitting the image in response to an image acquired from the CPU (211) during image transmission from the DPU (212) to the display driver circuit (231) executed via the first interface (241) for the fourth mode. This operation is exemplified in the description of FIG. 9.

[0118] FIG. 9 illustrates an exemplary method of stopping transmission of a first image and executing transmission of a second image according to a fourth mode in response to receiving a second image from at least one processor while scanning a first image, to stop scanning the first image and scan the second image.

[0119] Referring to FIG. 9, the DPU (212) may transmit (400) the first image acquired from the CPU (211) to the display driving circuit (231) through the first interface (241), according to the fourth mode, from the start time (921) of the light-emitting section (550). As a non-limiting example, the time length (551) of the light-emitting section (550) may be 1 / 240 (s). The display driving circuit (231) may display the first image on the active area of ​​the display panel (232) as in the state (961) by scanning the first image received from the DPU (212) as indicated by the arrow (401).

[0120] For example, the display driving circuit (231) may change the state of a signal (990) (e.g., a TE (tearing effect) signal) from the display driving circuit (231) to the at least one processor (210) from a first state to a second state, such as state (991), based on a command from at least one processor (210) or a decision of the display driving circuit (231). For example, the change from the first state to the second state, such as state (991), may be performed to request repeated display of the first image.

[0121] For example, in response to the change from the first state, such as state (991), to the second state, the DPU (212) may transmit (900) the first image acquired from the memory (220) (e.g., the DRAM)) to the display driver circuit (231) through the first interface (241), from the start time (922) of the light-emitting period (550), according to the fourth mode. For example, the DPU (212) may transmit (900) the first image to perform repeated display of the first image on the active area. For example, the display driver circuit (231) may change the state of the signal (990) from the second state to the first state, such as state (992), in response to the first image received from the DPU (212). For example, the display driving circuit (231) can scan the first image received again from the DPU (212).

[0122] For example, the CPU (211) may generate (301) (or acquire (301)) a second image to be changed from (or subsequent to) the first image before scanning the first image for the repeated display of the first image is completed. For example, the CPU (211) may request the DPU (212) to transmit the second image to the display driving circuit (231) using a program stored in the memory (220). As a non-limiting example, the program may include a program included in a hardware abstraction layer (HAL) for controlling the display (230). As a non-limiting example, the program may include instructions executable by the CPU (211). For example, the DPU (212) can control the display driving circuit (231) to stop scanning the first image and scan the second image by executing (302) from the start time (923) of the light-emitting section (550) the step of stopping transmitting the first image in response to the request from the CPU (211) and transmitting the second image to the display driving circuit (231) through the first interface (241) according to the fourth mode. For example, the second image can be received in a state in which a portion of the first image has been scanned as indicated by arrow (303) (or a state in which a remaining portion of the first image has not been scanned). For example, the display driving circuit (231) can cancel, skip, omit, bypass, or refrain from scanning the remaining portion of the first image as indicated by arrow (304) by stopping scanning the first image in response to the second image received from the start time (923).For example, the remaining portion of the first image may not be scanned by the display driving circuit (231) upon reception of the second image, unlike the portion of the first image that is scanned by the display driving circuit (231) prior to reception of the second image. For example, displaying the portion of the first image, such as in state (962), is performed by scanning the portion of the first image, but displaying the remaining portion of the first image may be canceled, skipped, omitted, bypassed, or avoided by skipping scanning the remaining portion of the first image.

[0123] For example, the display driving circuit (231) can display the second image on the active area as in state (963) by scanning the second image received after the portion of the first image is received as indicated by arrow (305).

[0124] As described above, the electronic device (100) can support multi-frequency driving of the display (230) by using the DPU (212) to stop transmitting the first image and transmit the second image in response to a request from the CPU (211) obtained while transmitting the first image in response to a request from the display driving circuit (231).

[0125] The above-exemplified operations can be executed within the electronic device (1001) exemplified in the descriptions of FIGS. 10 and 11.

Each of the external electronic devices (1002 or 1004) may be the same or a different type of device as the electronic device (1001). According to one embodiment, all or part of the operations executed in the electronic device (1001) may be executed in one or more of the external electronic devices (1002, 1004, or 1008). For example, when the electronic device (1001) is to perform a certain function or service automatically or in response to a request from a user or another device, the electronic device (1001) may, instead of or in addition to executing the function or service itself, request one or more external electronic devices to perform the function or at least a part of the service.

Referring to FIG. 11, the display module (1060) may include a display (1110) and a display driver IC (DDI) (1130) for controlling the display (1110). The DDI (1130) may include an interface module (1131), a memory (1133) (e.g., a buffer memory), an image processing module (1135), or a mapping module (1137). The DDI (1130) may receive image information including, for example, image data or an image control signal corresponding to a command for controlling the image data, from another component of the electronic device (1001) through the interface module (1131). For example, according to one embodiment, image information may be received from a processor (1020) (e.g., a main processor (1021) (e.g., an application processor) or an auxiliary processor (1023) (e.g., a graphics processing unit) that operates independently of the function of the main processor (1021).

For example, when the sensor module (1076) embedded in the display module (1060) 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 (1110). For another example, if the sensor module (1076) embedded in the display module (1060) 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 (1110). According to one embodiment, the touch sensor (1151) or the sensor module (1076) may be disposed between pixels of a pixel layer of the display (1110), or above or below the pixel layer.

[0161] The at least one processor may include a central processing unit (CPU) including a processing circuit and a display processing unit (DPU) including a processing circuit. The memory may store instructions that cause the DPU to control the display driving circuit to scan the first image by transmitting the first image to the display driving circuit based on a change in a state of a signal received from the display driving circuit according to an adaptive refresh panel (ARP) of a mobile industry processor interface (MIPI) display serial interface (DSI), and to control the display driving circuit to stop transmitting the first image to the display driving circuit and to transmit the second image to the display driving circuit in response to obtaining the second image from the CPU while transmitting the first image to the display driving circuit, thereby stopping scanning the first image and scanning the second image.

[0162] A method executed in an electronic device (e.g., electronic device (100)) having at least one processor (e.g., at least one processor (210)), a display driving circuit (e.g., a display driving circuit (231)), and a display panel (e.g., a display panel (232)), as described above, may include an operation in which the display driving circuit scans a first image to be displayed on an active area of ​​the display panel, and an operation in which the display driving circuit provides a first refresh rate for a portion of the active area in which a portion of the scanned first image is displayed and a second refresh rate for a remaining portion of the active area differently from each other by stopping scanning the first image and scanning a second image to be displayed on the active area in response to a second image received from the at least one processor before scanning of the first image is completed, until the second image is received.
