The data may be received from a time different from times corresponding to the second refresh rate.

[0010] 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.

[0011] Figure 2 is a simplified block diagram of an exemplary electronic device.

[0012] Figures 3 and 4 illustrate an exemplary method for requesting data for an image to be displayed on a portion of an active area while performing multi-frequency driving of a display panel.

[0013] FIG. 5 is a block diagram of an electronic device within a network environment according to various embodiments.

[0014] FIG. 6 is a block diagram of a display module according to various embodiments.

[0015] 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.

[0016] 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).

[0017] 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).

[0018] 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.

[0019] 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.

[0020] 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.

[0021] 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.

[0022] 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 multi-frequency driving. For example, the electronic device (100) may include components (e.g., hardware components) for the multi-frequency driving. The components are exemplified in the description of FIG. 2.

[0023] Figure 2 is a simplified block diagram of an exemplary electronic device.

[0024] Referring to FIG. 2, the electronic device (100) may include at least one processor (210), memory (220), and display (230).

[0025] 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). 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 include at least a portion of the processor (520) of FIG. 5 or may correspond to at least a portion of the processor (520) of FIG. 5.

[0026] 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).

[0027] 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).

[0028] 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.

[0029] For example, the memory (220) may include at least a portion of the memory (530) of FIG. 5 or may correspond to at least a portion of the memory (530) of FIG. 5.

[0030] 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 (560) of FIGS. 5 and 6 or may correspond to at least a portion of the display module (560) of FIGS. 5 and 6. For example, the display (230) may include a display driver circuit (231) (e.g., including at least a portion of the display driver IC (630) of FIG. 6 or corresponding to at least a portion of the display driver IC (630) of FIG. 6) and a display panel (232) (e.g., including at least a portion of the display (610) of FIG. 6 or corresponding to at least a portion of the display (610) of FIG. 6).

[0031] The display driving circuit (231) may be a hardware component of the electronic device (100) that is available 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 (202) may be configured to receive data (e.g., frame data) from at least one processor (210) and control the display panel (232) to display the screen (or one or more images) using the data.

[0032] 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).

[0033] 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).

[0034] 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 an adaptive refresh panel (ARP) of a MIPI display serial interface (DSI). For example, the display driving circuit (231) operated (driven) according to the ARP can display the image on the active area of ​​the display panel (232) by scanning the image received from the at least one processor (210) without using the memory (e.g., the memory configured to at least temporarily store frame data (e.g., graphic random access memory (GRAM))) within the display driving circuit (231). As a non-limiting example, the at least one processor (210) may not execute determining (or identifying) (or confirming) whether to (re)transmit the image for repeated display of the image according to the ARP. For example, for the ARP, the display driving circuit (231) displays the image without using the memory within the display driving circuit (231) and the at least one processor (210) refrains from determining whether to transmit the image for repeated display, so that the display driving circuit (231) can display the image on the display panel (232) according to the ARP. A request to perform can be transmitted to at least one processor (210).For example, the display driving circuit (231) may change the state of a signal (e.g., a TE (tearing effect) signal) transmitted from the display driving circuit (231) to at least one processor (210) in order to transmit the request according to the ARP. Changing the state of the signal will be illustrated in more detail within the description of FIGS. 3 and 4.

[0035] 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) that is available for a signal (e.g., a synchronization signal) (e.g., a tearing effect signal (TE)) 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).

[0036] For example, the one or more interfaces may include a third interface (243). The third interface (243) may be a hardware component of the electronic device (100) that is available for information to be transmitted from the display driving circuit (231) to at least one processor (210). As a non-limiting example, the third interface (243) may include SPI, UART, I2C, or I2C.

[0037] 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) a 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 a 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 displaying the part of the active area and to refrain from scanning for displaying the other part of the active area according to the multi-frequency driving, the display driving circuit (231) can perform displaying the second part of the active area according to a refresh rate that is different from the refresh rate for displaying the first part of the active area.

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

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

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

[0041] For example, the display driving circuit (231) can display data received from at least one processor (210) (or a processor (e.g., DPU)) based on the first refresh rate on a first portion of the display panel (232) (or a first portion of the active area of ​​the display panel (232), and can display data received from at least one processor (210) (or a processor (e.g., DPU)) based on the second refresh rate on a second portion of the display panel (232) (or a second portion of the active area). For example, the display driving circuit (231) can transmit a request for data to be displayed on the second portion of the display panel (232) to the at least one processor (210). For example, the display driving circuit (231) may display, on the second portion of the display panel (232), data received from at least one processor (210) in association with the request from a time point other than the time points corresponding to the second refresh rate. For example, the request may be transmitted from the display driving circuit (231) to the at least one processor (210) according to the ARP. For example, the request may be transmitted from the display driving circuit (231) to the at least one processor (210) independently of receiving data for the first portion of the display panel (232) from the at least one processor (210) based on the first refresh rate.

[0042] For example, since the first refresh rate may correspond to the time that the first image is maintained on the display panel (232), an afterimage may occur on the first portion of the active area when the first refresh rate is lower than the reference refresh rate. For example, since the second refresh rate may correspond to the time that the second image is maintained on the display panel (232), an afterimage may occur on the second portion of the active area when the second refresh rate is lower than the reference refresh rate.

[0043] For example, the first refresh rate may be changed from a third refresh rate that is different from the first refresh rate. For example, the third refresh rate may be higher or lower than the first refresh rate. For example, the third refresh rate may correspond to a time interval between displays on the first portion of the active area performed by the display driving circuit (231) before (or immediately before) the first refresh rate is used for display on the first portion of the active area. For example, when a difference value between the first refresh rate and the third refresh rate is higher than a threshold value, flickering may occur on the first portion of the active area due to displaying the image received according to the first refresh rate on the first portion of the active area.

[0044] For example, the second refresh rate may be changed from a fourth refresh rate that is different from the second refresh rate. For example, the fourth refresh rate may be higher or lower than the second refresh rate. For example, the fourth refresh rate may correspond to a time interval between displays on the second portion of the active area performed by the display driving circuit (231) before (or immediately before) the second refresh rate is used for display on the second portion of the active area. For example, when a difference value between the second refresh rate and the fourth refresh rate is higher than a threshold value, flickering may occur on the second portion of the active area due to displaying the image received according to the second refresh rate on the first portion of the active area.

[0045] For example, the display driving circuit (231) may display a first image received from at least one processor (210) according to the first refresh rate on the first portion of the active area, while displaying a second image received from at least one processor (210) according to the second refresh rate on the second portion of the active area. For example, the display driving circuit (231) may request data to be displayed on the second portion of the active area according to the second refresh rate, from the at least one processor (210), while the first image is maintained on the first portion of the active area and the second image is maintained on the second portion of the active area. For example, requesting the data may be executed by the display driving circuit (231) to reduce the afterimage and / or the flicker. As a non-limiting example, requesting the data may be executed by the display driver circuit (231) to perform repeated display of the second image on the second portion of the active area. For example, the display driver circuit (231) may receive the data transmitted from at least one processor (210) in response to the request via the first interface (241). For example, the display driver circuit (231) may use the data received from at least one processor (210) via the first interface (241) to perform the repeated display of the second image on the second portion of the active area to reduce the afterimage and / or the flicker. For example, the repeated display of the second image may be performed while the first image is maintained on the first portion of the active area.As a non-limiting example, the refresh rate on the second portion of the active area may be higher than the second refresh rate, depending on the repeated display of the second image. These operations are described in more detail in the descriptions of FIGS. 3 and 4.

[0046] Figures 3 and 4 illustrate an exemplary method for requesting data for an image to be displayed on a portion of an active area while performing multi-frequency driving of a display panel.

[0047] Referring to FIG. 3, at least one processor (210) may transmit at least one command (303) for multi-frequency driving to the display driving circuit (231) via the first interface (241). For example, the at least one command (303) may include a command (301) and a command (302). For example, the command (301) may indicate enabling the multi-frequency driving. For example, the command (302) may indicate a configuration of the multi-frequency driving. As a non-limiting example, the command (302) may indicate a method of dividing the active area for the multi-frequency driving. For example, the command (302) may indicate that, for the multi-frequency driving, the active area is divided into a first area of ​​the active area (or a first part of the active area), a second area of ​​the active area (or a second part of the active area), a third area of ​​the active area (or a third part of the active area), a fourth area of ​​the active area (or a fourth part of the active area), and a fifth area of ​​the active area (or a fifth part of the active area). For example, the command (302) may include location information of the first area of ​​the active area, location information of the second area of ​​the active area, location information of the third area of ​​the active area, location information of the fourth area of ​​the active area, and location information of the fifth area of ​​the active area.As a non-limiting example, the command (302) may include information about a refresh rate (e.g., scheduled by at least one processor (210)) for an image displayed on the first area of ​​the active area (or information about a frame interval for display on the first area of ​​the active area), information about a refresh rate (e.g., scheduled by at least one processor (210)) for an image displayed on the second area of ​​the active area (or information about a frame interval for display on the second area of ​​the active area), information about a refresh rate (e.g., scheduled by at least one processor (210)) for an image displayed on the third area of ​​the active area (or information about a frame interval for display on the third area of ​​the active area), information about a refresh rate (e.g., scheduled by at least one processor (210)) for an image displayed on the fourth area of ​​the active area (or information about a frame interval for display on the fourth area of ​​the active area), and information about the It may include information about a refresh rate for an image displayed on the fifth region (e.g., a refresh rate scheduled by at least one processor (210)) (or information about a frame interval for display on the fifth region of the active area).

[0048] For example, at least one processor (210) may transmit a vertical synchronization signal (VSS) packet (304-1) to the display driving circuit (231) via the first interface (241) to indicate a start time (341) of a vertical synchronization signal (e.g., corresponding to one of the start times of a light-emitting period (390) capable of executing image transmission). For example, at least one processor (210) may, after transmitting a VSS packet (304-1), (sequentially) transmit an image (311) to be displayed on the first area of ​​the active area, an image (312) to be displayed on the second area of ​​the active area, an image (313) to be displayed on the third area of ​​the active area, an image (314) to be displayed on the fourth area of ​​the active area, and an image (315) to be displayed on the fifth area of ​​the active area to the display driving circuit (231) via the first interface (241).

[0049] For example, the display driving circuit (231) may perform a scan based on a start time (341) using images (311), (312), (313), (314), and (315) received (sequentially) from at least one processor (210) via the first interface (241), thereby displaying the image (311) on the first area of ​​the active area, displaying the image (312) on the second area of ​​the active area, displaying the image (313) on the third area of ​​the active area, displaying the image (314) on the fourth area of ​​the active area, and displaying the image (315) on the fifth area of ​​the active area.

[0050] For example, the display driving circuit (231) may request data (361) to be displayed on the first region of the active region and the fourth region of the active region among the first region of the active region, the second region of the active region, the third region of the active region, the fourth region of the active region, and the fifth region of the active region, from at least one processor (210), according to a refresh rate (e.g., scheduled by at least one processor (210)) for the image (311) displayed on the first region of the active region and a refresh rate (e.g., scheduled by at least one processor (210)) for the image (314) displayed on the fourth region of the active region while the image (311), the image (312), the image (313), the image (314), and the image (315) are maintained on the active region. For example, the display driving circuit (231) may request data (361) from at least one processor (210) based on a length of time that the image (311) is maintained on the first region of the active region and a length of time that the image (314) is maintained on the fourth region of the active region while the images (311), (312), (313), (314), and (315) are maintained on the active region. For example, the display driving circuit (231) may request data (361) from at least one processor (210) based on a frame interval for display on the first region of the active region and a frame interval for display on the fourth region of the active region while the images (311), (312), (313), (314), and (315) are maintained on the active region.For example, the frame interval for display on the first region of the active area may represent the shortest time interval of image transmission for display on the first region of the active area. For example, the frame interval for display on the fourth region of the active area may represent the shortest time interval of image transmission for display on the fourth region of the active area. For example, the display driving circuit (231) may request data (361) from at least one processor (210) based on a difference between a refresh rate used for display on the first region of the active region before the refresh rate for image (311) and the refresh rate for image (311) while images (311), (312), (313), (314), and (315) are maintained on the active region, and a difference between a refresh rate used for display on the fourth region of the active region before the refresh rate for image (314) and the refresh rate for image (314). As a non-limiting example, the data (361) may include information about the first region of the active region and the fourth region of the active region.

[0051] As a non-limiting example, requesting data (361) may be performed via the first interface (241) within the porch portion of the vertical synchronization signal. As a non-limiting example, requesting data (361) may be performed via the third interface (243). As a non-limiting example, requesting data (361) may also be performed via the second interface (242). For example, requesting data (361) may be performed to reduce afterimages and / or flickering that may occur on the first region of the active area and the fourth region of the active area. As a non-limiting example, data (361) may be requested to at least one processor (210) for repeated display of image (311) and repeated display of image (314).

[0052] For example, the request may include changing the state of a signal (e.g., the TE signal) transmitted from the display driver circuit (231) to at least one processor (210) via the second interface (242). For example, the display driver circuit (231) may change the state of the signal from a first state to a second state different from the first state, such as state (351), for the request. For example, the second state may indicate a request for an image to be displayed on the display panel (232) (or the active area), unlike the first state.

[0053] For example, at least one processor (210) may receive the request from the display driving circuit (231). For example, at least one processor (210) may generate (or obtain) a command (305-1) for multi-frequency driving based on (or in response to) the request. As a non-limiting example, the command (305-1) may indicate a location (e.g., the first region of the active area) at which an image (316) to be transmitted from the at least one processor (210) is to be displayed and a location (e.g., the fourth region of the active area) at which an image (317) to be transmitted from the at least one processor (210) is to be displayed. For example, at least one processor (210) may transmit the command (305-1) to the display driving circuit (231) via the first interface (241). For example, the display driving circuit (231) can receive a command (305-1) from at least one processor (210).

[0054] For example, at least one processor (210) may transmit, to the display driving circuit (231), a VSS packet (304-2) to indicate a start time (342) of a vertical synchronization signal for displaying images (316) and images (317) (e.g., corresponding to a start time of one of the start times of the light-emitting sections (390) capable of executing image transmission). For example, the VSS packet (304-2) may be transmitted for display on a portion of the active area (e.g., display on the first area and the fourth area), unlike the VSS packet (304-1) that is transmitted for display on the active area. For example, the VSS packet (304-2) may be transmitted for changing an image displayed on a portion of the active area. For example, the display driver circuit (231) may change the state of the signal from the second state to the first state, such as state (352), based on (or in response to) a VSS packet (304-2) received from at least one processor (210). For example, the change from the second state to the first state may be performed for one or more images (e.g., image (316) and image (317)) to be received after the VSS packet (304-2).

[0055] For example, at least one processor (210) may transmit data (e.g., data (361)) including an image (316) to be displayed on the first region of the active area and an image (317) to be displayed on the fourth region of the active area, to the display driving circuit (231) via the first interface (241), after transmitting the VSS packet (304-2). For example, the image (316) may be transmitted for a time duration corresponding to the first region of the active area, and the image (317) may be transmitted for a time duration corresponding to the fourth region of the active area. For example, the at least one processor (210) may support multi-frequency driving of the display (230) by transmitting the image (316) and the image (317) and not transmitting the image to be displayed on the second region of the active area, the image to be displayed on the third region of the active area, and the image to be displayed on the fifth region of the active area. For example, image (316) may be identical to image (311) or may be at least partially different from image (311). For example, image (317) may be identical to image (314) or may be at least partially different from image (314).

[0056] For example, the display driving circuit (231) can display an image (316) on the first region of the active area and display an image (317) on the fourth region of the active area, while the images (312), (313), and (315) are maintained on the active area, using the data received from at least one processor (210) via the first interface (241). For example, when the image (316) is identical to the image (311) and the image (317) is identical to the image (314), the display driving circuit (231) can perform repeated display on the first region of the active area and repeated display on the fourth region of the active area, while the images (312), (313), and (315) are maintained on the active area, using the data received from at least one processor (210) via the first interface (241). As a non-limiting example, the display driving circuit (231) may recognize that the data received from at least one processor (210) is to be used to perform the repeated display on the first area of ​​the active area and the repeated display on the fourth area of ​​the active area by performing a CRC (cyclic redundancy check) on the data, and based on the recognition, may perform the repeated display on the first area of ​​the active area and the repeated display on the fourth area of ​​the active area. For example, the display driving circuit (231) may perform a scan based on a start time (342) using the image (316) and the image (317), thereby displaying the image (316) on the first area of ​​the active area and displaying the image (317) on the fourth area of ​​the active area.

[0057] For example, the display driving circuit (231) may request data (362) to be displayed on the second region of the active region and the third region of the active region among the first region of the active region, the second region of the active region, the third region of the active region, the fourth region of the active region, and the fifth region of the active region, from at least one processor (210), according to a refresh rate (e.g., scheduled by at least one processor (210)) for the image (312) displayed on the second region of the active region and a refresh rate (e.g., scheduled by at least one processor (210)) for the image (313) displayed on the third region of the active region while the image (316), the image (312), the image (313), the image (317), and the image (315) are maintained on the active region. For example, the display driving circuit (231) may request data (362) from at least one processor (210) based on a length of time that the image (312) is maintained on the second region of the active region and a length of time that the image (313) is maintained on the third region of the active region while the images (316), (312), (313), (317), and (315) are maintained on the active region. For example, the display driving circuit (231) may request data (362) from at least one processor (210) based on a frame interval for display on the second region of the active region and a frame interval for display on the third region of the active region while the images (316), (312), (313), (317), and (315) are maintained on the active region.For example, the frame interval for display on the second region of the active area may represent the shortest time interval of image transmission for display on the second region of the active area. For example, the frame interval for display on the third region of the active area may represent the shortest time interval of image transmission for display on the third region of the active area. For example, the display driving circuit (231) may request data (362) from at least one processor (210) based on a difference between a refresh rate used for display on the second region of the active region and the refresh rate for the image (312) prior to the refresh rate for the image (312), and a difference between a refresh rate used for display on the third region of the active region and the refresh rate for the image (313) prior to the refresh rate for the image (313), while the images (316), (312), (313), (317), and (315) are maintained on the active region. As a non-limiting example, the data (362) may include information about the second region of the active region and the third region of the active region.

[0058] As a non-limiting example, requesting data (362) may be performed via the first interface (241) within the porch portion of the vertical synchronization signal. As a non-limiting example, requesting data (362) may be performed via the third interface (243). As a non-limiting example, requesting data (362) may also be performed via the second interface (242). For example, requesting data (362) may be performed to reduce afterimages and / or flickering that may occur on the second region of the active region and the third region of the active region. As a non-limiting example, data (362) may be requested to at least one processor (210) for repeated display of image (312) and repeated display of image (313).

[0059] For example, the request may include changing the state of a signal (e.g., the TE signal) transmitted from the display driver circuit (231) to at least one processor (210) via the second interface (242). For example, the display driver circuit (231) may change the state of the signal from a first state to a second state, such as state (353), for the request. For example, the time for performing the change from the first state to the second state, such as state (353), may be determined based on a state of at least one processor (210) (e.g., the time of a previous image transmission executed by the at least one processor (210). As a non-limiting example, the display driving circuit (231) may determine a time for changing the state of the signal from the first state to the second state, and perform the change from the first state to the second state from the determined time, such as state (353), to reduce a delay in processing according to the request that occurs due to a decrease in the operating frequency of at least one processor (210).

[0060] For example, at least one processor (210) may receive the request from the display driving circuit (231). For example, at least one processor (210) may generate (or obtain) a command (305-2) for multi-frequency driving based on (or in response to) the request. As a non-limiting example, the command (305-2) may indicate a location (e.g., the second region of the active area) at which an image (318) to be transmitted from the at least one processor (210) is to be displayed and a location (e.g., the third region of the active area) at which an image (319) to be transmitted from the at least one processor (210) is to be displayed. For example, at least one processor (210) may transmit the command (305-2) to the display driving circuit (231) via the first interface (241). For example, the display driving circuit (231) can receive a command (305-2) from at least one processor (210).

[0061] For example, at least one processor (210) may transmit, to the display driving circuit (231), a VSS packet (304-3) via the first interface (241) to indicate a start time (343) of a vertical synchronization signal for displaying images (318) and images (319) (e.g., corresponding to a start time of one of the start times of the light-emitting period (390) in which image transmission can be executed). For example, the VSS packet (304-3) may be transmitted for display on a portion of the active area (e.g., display on the second area and the third area), unlike the VSS packet (304-1) which is transmitted for display on the active area. For example, the VSS packet (304-3) may be transmitted to change an image displayed on a portion of the active area. For example, the display driver circuit (231) may change the state of the signal from the second state to the first state, such as state (354), based on (or in response to) a VSS packet (304-3) received from at least one processor (210). For example, the change from the second state to the first state may be performed for one or more images (e.g., image (318) and image (319)) to be received after the VSS packet (304-3).

[0062] For example, at least one processor (210) may transmit data (e.g., data (362)) including an image (318) to be displayed on the second region of the active area and an image (319) to be displayed on the third region of the active area, to the display driving circuit (231) via the first interface (241), after transmitting the VSS packet (304-3). For example, the image (318) may be transmitted for a time length corresponding to the second region of the active area, and the image (319) may be transmitted for a time length corresponding to the third region of the active area. For example, the at least one processor (210) may support multi-frequency driving of the display (230) by transmitting the image (318) and the image (319) and not transmitting the image to be displayed on the first region of the active area, the image to be displayed on the fourth region of the active area, and the image to be displayed on the fifth region of the active area. For example, image (318) may be identical to image (312) or may be at least partially different from image (312). For example, image (319) may be identical to image (313) or may be at least partially different from image (313).

[0063] For example, the display driving circuit (231) can perform, using the data received from at least one processor (210) via the first interface (241), displaying an image (318) on the second region of the active area and displaying an image (319) on the third region of the active area while the images (316), (317), and (315) are maintained on the active area. For example, when the image (318) is identical to the image (312) and the image (319) is identical to the image (313), the display driving circuit (231) can perform, using the data received from at least one processor (210) via the first interface (241), repeated display on the second region of the active area and repeated display on the third region of the active area while the images (316), (317), and (315) are maintained on the active area. As a non-limiting example, the display driving circuit (231) may recognize that the data received from at least one processor (210) is to be used to perform the repeated display on the second area of ​​the active area and the repeated display on the third area of ​​the active area by performing a CRC (cyclic redundancy check) on the data, and based on the recognition, may perform the repeated display on the second area of ​​the active area and the repeated display on the third area of ​​the active area. For example, the display driving circuit (231) may perform a scan based on a start time (343) using the image (318) and the image (319), thereby displaying the image (318) on the second area of ​​the active area and displaying the image (319) on the third area of ​​the active area.

[0064] For example, the display driving circuit (231) may request data (363) to be displayed on the fifth region of the active region among the first region of the active region, the second region of the active region, the third region of the active region, the fourth region of the active region, and the fifth region of the active region, from at least one processor (210), according to a refresh rate (e.g., scheduled by at least one processor (210)) of the image (315) displayed on the fifth region of the active region while the image (316), the image (318), the image (319), the image (317), and the image (315) are maintained on the active region. For example, the display driving circuit (231) may request data (363) from at least one processor (210) based on a length of time that the image (315) is maintained on the fifth region of the active area while the images (316), (318), (319), (317), and (315) are maintained on the active area. For example, the display driving circuit (231) may request data (363) from at least one processor (210) based on a frame interval for display on the fifth region of the active area while the images (316), (318), (319), (317), and (315) are maintained on the active area. For example, the frame interval for display on the fifth region of the active area may represent a shortest time interval of image transmission for display on the fifth region of the active area.For example, the display driving circuit (231) may request data (363) from at least one processor (210) based on a difference between a refresh rate used for display on the fifth region of the active region prior to the refresh rate for image (315) and the refresh rate for image (315) while the image (316), image (318), image (319), image (317), and image (315) are maintained on the active region. As a non-limiting example, the data (363) may include information about the fifth region of the active region.

[0065] As a non-limiting example, requesting data (363) may be performed via the first interface (241) within the porch portion of the vertical synchronization signal. As a non-limiting example, requesting data (363) may be performed via the third interface (243). As a non-limiting example, requesting data (363) may also be performed via the second interface (242). For example, requesting data (363) may be performed to reduce afterimages and / or flickering that may occur on the fifth region of the active area. As a non-limiting example, data (363) may be requested to at least one processor (210) for repeated display of the image (315).

[0066] For example, the request may include changing the state of a signal (e.g., the TE signal) transmitted from the display driver circuit (231) to at least one processor (210) via the second interface (242). For example, the display driver circuit (231) may change the state of the signal from a first state to a second state, such as state (355), for the request. For example, the time for performing the change from the first state to the second state, such as state (355), may be determined based on a state of at least one processor (210) (e.g., the time of a previous image transmission executed by the at least one processor (210). As a non-limiting example, the display driving circuit (231) may determine a time for changing the state of the signal from the first state to the second state, and perform the change from the first state to the second state from the determined time, such as state (355), to reduce a delay in processing according to the request that occurs due to a decrease in the operating frequency of at least one processor (210).

[0067] For example, at least one processor (210) may receive the request from the display driving circuit (231). For example, at least one processor (210) may generate (or obtain) a command (305-3) for multi-frequency driving based on (or in response to) the request. As a non-limiting example, the command (305-3) may indicate a location (e.g., the fifth region of the active area) where the image (320) to be transmitted from the at least one processor (210) is to be displayed. For example, at least one processor (210) may transmit the command (305-3) to the display driving circuit (231) via the first interface (241). For example, the display driving circuit (231) may receive the command (305-3) from the at least one processor (210).

[0068] For example, at least one processor (210) may transmit, to the display driving circuit (231), a VSS packet (304-4) via the first interface (241) to indicate a start time (345) of a vertical synchronization signal for displaying an image (320) (e.g., corresponding to a start time of one of the start times of the light-emitting section (390) capable of executing image transmission). For example, the VSS packet (304-4) may be transmitted for display on a portion of the active area (e.g., display on the fifth area), unlike the VSS packet (304-1) that is transmitted for display on the active area. For example, the VSS packet (304-4) may be transmitted for changing an image displayed on a portion of the active area. For example, the display driver circuit (231) may change the state of the signal from the second state to the first state, such as state (356), based on (or in response to) a VSS packet (304-4) received from at least one processor (210). For example, the change from the second state to the first state may be performed for one or more images (e.g., image (320)) to be received after the VSS packet (304-4).

[0069] For example, at least one processor (210) may transmit data (e.g., data (363)) including an image (320) to be displayed on the fifth region of the active area, to the display driving circuit (231) via the first interface (241), after transmitting the VSS packet (304-4). For example, the image (320) may be transmitted for a length of time corresponding to the fifth region of the active area. For example, at least one processor (210) may support multi-frequency driving of the display (230) by transmitting the image (320) and not transmitting the image to be displayed on the first region of the active area, the image to be displayed on the second region of the active area, the image to be displayed on the third region of the active area, and the image to be displayed on the fourth region. For example, the image (320) may be identical to the image (315) or may be at least partially different from the image (315).

[0070] For example, the display driving circuit (231) can display an image (320) on the fifth region of the active area while the images (316), (318), (319), and (317) are maintained on the active area by using the data received from at least one processor (210) via the first interface (241). For example, when the image (320) is identical to the image (315), the display driving circuit (231) can perform repeated display on the fifth region of the active area while the images (316), (318), (319), and (317) are maintained on the active area by using the data received from at least one processor (210) via the first interface (241). As a non-limiting example, the display driving circuit (231) may recognize that the data received from at least one processor (210) is to be used to perform the repeated display on the fifth region of the active area by performing a CRC (cyclic redundancy check) on the data, and may perform the repeated display on the fifth region of the active area based on the recognition. For example, the display driving circuit (231) may display the image (320) on the fifth region of the active area by performing a scan based on a start time (345) using the image (320).

[0071] For example, the display driving circuit (231) may request data (364) to be displayed on the second region of the active region, the third region of the active region, the fourth region of the active region, and the fifth region of the active region from at least one processor (210), according to a refresh rate (e.g., scheduled by at least one processor (210)) of an image (318) displayed on the second region of the active region, a refresh rate (e.g., scheduled by at least one processor (210)) of an image (319) displayed on the third region of the active region, and a refresh rate (e.g., scheduled by at least one processor (210)) of an image (320) displayed on the fifth region of the active region, while the image (316), the image (318), the image (319), the image (317), and the image (320) are maintained on the active region. For example, the display driving circuit (231) may request data (364) from at least one processor (210) based on a length of time that the image (318) is maintained on the second region of the active region, a length of time that the image (319) is maintained on the third region of the active region, and a length of time that the image (320) is maintained on the fifth region of the active region while the image (316), the image (318), the image (319), the image (317), and the image (320) are maintained on the active region.For example, the display driving circuit (231) may request data (364) from at least one processor (210) based on a frame interval for display on the second area of ​​the active area, a frame interval for display on the third area of ​​the active area, and a frame interval for display on the fifth area of ​​the active area while the image (316), the image (318), the image (319), the image (317), and the image (320) are maintained on the active area. For example, the display driving circuit (231) may request data (364) from at least one processor (210) based on a difference between a refresh rate for image (312) and a refresh rate for image (318), a difference between a refresh rate for image (313) and a refresh rate for image (319), and a difference between a refresh rate for image (315) and a refresh rate for image (320) while images (316), (318), (319), (317), and (320) are maintained on the active area. As a non-limiting example, the data (364) may include information about the second area of ​​the active area, the third area of ​​the active area, and the fifth area of ​​the active area.

[0072] As a non-limiting example, requesting data (364) may be performed via a first interface (241) within the porch portion of the vertical synchronization signal. As a non-limiting example, requesting data (364) may be performed via a third interface (243). As a non-limiting example, requesting data (364) may also be performed via a second interface (242). For example, requesting data (364) may be performed to reduce afterimages and / or flickering that may occur on the second region of the active region, the third region of the active region, and the fifth region of the active region. As a non-limiting example, data (364) may be requested to at least one processor (210) for repeated display of image (318), repeated display of image (319), and repeated display of image (320).

[0073] For example, the request may include changing the state of a signal (e.g., the TE signal) transmitted from the display driver circuit (231) to at least one processor (210) via the second interface (242). For example, the request may be ignored by the at least one processor (210). For example, the at least one processor (210) may transmit a command (306) to the display driver circuit (231) via the first interface (241) before the display driver circuit (231) changes the state of the signal from the first state to the second state for the request. For example, the command (306) may indicate disabling the multi-frequency driving.

[0074] For example, at least one processor (210) may transmit, to the display driving circuit (231) via the first interface (241), a VSS packet (304-5) to indicate a start time (346) of a vertical synchronization signal (e.g., corresponding to a start time of one of the start times of the light-emitting section (390) capable of executing image transmission). For example, after transmitting the VSS packet (304-5), the at least one processor (210) may transmit, to the display driving circuit (231) via the first interface (241), an image (321) to be displayed on the active area.

[0075] For example, the display driving circuit (231) can display the image (321) on the active area by performing a scan based on a start time (346) using an image (321) received from at least one processor (210) through the first interface (241).

[0076] As described above, the electronic device (100) can reduce the afterimage and / or flicker that may occur while supporting multi-frequency driving of the display (230) by using a request from the display driving circuit (231).

[0077] Referring to FIG. 4, at least one processor (210) may transmit at least one command (303) for multi-frequency driving to the display driving circuit (231) via the first interface (241). For example, the at least one command (303) may include a command (301) and a command (302). For example, the command (301) may indicate activating the multi-frequency driving. For example, the command (302) may indicate a configuration of the multi-frequency driving. As a non-limiting example, the command (302) may indicate a method of dividing the active area for the multi-frequency driving. For example, the command (302) may indicate that, for the multi-frequency driving, the active area is divided into a first area of ​​the active area (or a first part of the active area), a second area of ​​the active area (or a second part of the active area), a third area of ​​the active area (or a third part of the active area), a fourth area of ​​the active area (or a fourth part of the active area), and a fifth area of ​​the active area (or a fifth part of the active area). For example, the command (302) may include location information of the first area of ​​the active area, location information of the second area of ​​the active area, location information of the third area of ​​the active area, location information of the fourth area of ​​the active area, and location information of the fifth area of ​​the active area.As a non-limiting example, the command (302) may include information about a refresh rate (e.g., scheduled by at least one processor (210)) for an image displayed on the first area of ​​the active area, information about a refresh rate (e.g., scheduled by at least one processor (210)) for an image displayed on the second area of ​​the active area, information about a refresh rate (e.g., scheduled by at least one processor (210)) for an image displayed on the third area of ​​the active area, information about a refresh rate (e.g., scheduled by at least one processor (210)) for an image displayed on the fourth area of ​​the active area, and information about a refresh rate (e.g., scheduled by at least one processor (210)) for an image displayed on the fifth area of ​​the active area.

[0078] For example, at least one processor (210) may transmit a vertical synchronization signal (VSS) packet (304-6) to the display driving circuit (231) via the first interface (241) to indicate a start time (441) of a vertical synchronization signal (e.g., corresponding to a start time of one of the start times of an emission period (390) in which image transmission can be executed). For example, at least one processor (210) may, after transmitting a VSS packet (304-6), (sequentially) transmit an image (411) to be displayed on the first area of ​​the active area, an image (412) to be displayed on the second area of ​​the active area, an image (413) to be displayed on the third area of ​​the active area, an image (414) to be displayed on the fourth area of ​​the active area, and an image (415) to be displayed on the fifth area of ​​the active area to the display driving circuit (231) via the first interface (241).

[0079] For example, the display driving circuit (231) may perform a scan based on a start time (441) using images (411), (412), (413), (414), and (415) received (sequentially) from at least one processor (210) via the first interface (241), thereby displaying the image (411) on the first area of ​​the active area, displaying the image (412) on the second area of ​​the active area, displaying the image (413) on the third area of ​​the active area, displaying the image (414) on the fourth area of ​​the active area, and displaying the image (415) on the fifth area of ​​the active area.

[0080] For example, at least one processor (210) can generate (or obtain) an image (416) to be displayed on the second region of the active region and an image (417) to be displayed on the third region of the active region while the images (411), (412), (413), (414), and (415) are maintained on the active region. For example, at least one processor (210) can generate (or obtain) a command (305-4) based on (or in response to) generating (or obtaining) the images (416) and (417). As a non-limiting example, the command (305-4) may indicate a location (e.g., the second region of the active area) at which an image (e.g., image (416)) to be transmitted from at least one processor (210) is to be displayed and a location (e.g., the third region of the active area) at which an image (e.g., image (417)) to be transmitted from at least one processor (210) is to be displayed. For example, the at least one processor (210) may transmit the command (305-4) to the display driver circuit (231) via the first interface (241). For example, the display driver circuit (231) may receive the command (305-4) from the at least one processor (210).

[0081] For example, at least one processor (210) may transmit, to the display driving circuit (231), a VSS packet (304-7) via the first interface (241) to indicate a start time (443) of a vertical synchronization signal for displaying images (416) and images (417) (e.g., corresponding to a start time of one of the start times of the light-emitting sections (390) capable of executing image transmission). For example, the VSS packet (304-7) may be transmitted for display on a portion of the active area (e.g., display on the second area and the third area), unlike the VSS packet (304-6) which is transmitted for display on the active area. For example, the VSS packet (304-7) may be transmitted to change an image displayed on a portion of the active area. For example, at least one processor (210) may transmit data including an image (416) and an image (417) to be displayed on the second region of the active area and the third region of the active area, to the display driving circuit (231) via the first interface (241), after transmitting the VSS packet (304-7). For example, the image (416) may be transmitted for a time length corresponding to the second region of the active area, and the image (417) may be transmitted for a time length corresponding to the third region of the active area. For example, the at least one processor (210) may support multi-frequency driving of the display (230) by transmitting the image (416) and the image (417) and not transmitting the image to be displayed on the first region of the active area, the image to be displayed on the fourth region of the active area, and the image to be displayed on the fifth region of the active area. For example, image (416) may be identical to image (412) or may be at least partially different from image (412).For example, image (417) may be identical to image (413) or may be at least partially different from image (413).

[0082] For example, the display driving circuit (231) may display an image (416) on the second region of the active region and display an image (417) on the third region of the active region while the image (411), the image (414), and the image (415) are maintained on the active region, using the data received from at least one processor (210) via the first interface (241). Displaying the image (416) on the second region of the active region and displaying the image (417) on the third region of the active region may be performed based on a start time (443).

[0083] For example, the display driving circuit (231) may, while the image (411), the image (416), the image (417), the image (414), and the image (415) are maintained on the active area, according to a refresh rate (e.g., scheduled by at least one processor (210)) of the image (411) displayed on the first area of ​​the active area, a refresh rate (e.g., scheduled by at least one processor (210)) of the image (416) displayed on the second area of ​​the active area, and a refresh rate (e.g., scheduled by at least one processor (210)) of the image (417) displayed on the third area of ​​the active area, data (461) to be displayed on the first area of ​​the active area, the second area of ​​the active area, the third area of ​​the active area, the fourth area of ​​the active area, and the fifth area of ​​the active area, At least one processor (210) may be requested. For example, the display driving circuit (231) may request data (461) from at least one processor (210) based on the length of time that the image (411) is maintained, the length of time that the image (416) is maintained, and the length of time that the image (417) is maintained while the image (411), the image (416), the image (417), the image (414), and the image (415) are maintained on the active area.For example, the display driving circuit (231) may request data (461) from at least one processor (210) based on a frame interval for display on the first area of ​​the active area, a frame interval for display on the second area of ​​the active area, and a frame interval for display on the third area of ​​the active area while the images (411), (416), (417), (414), and (415) are maintained on the active area. The frame interval for display on the first area of ​​the active area may represent a shortest time interval for image transmission for display on the first area of ​​the active area. The frame interval for display on the second area of ​​the active area may represent a shortest time interval for image transmission for display on the second area of ​​the active area. The frame interval for display on the third area of ​​the active area may represent a shortest time interval for image transmission for display on the third area of ​​the active area. For example, the display driving circuit (231) may request data (461) from at least one processor (210) based on a difference between a refresh rate used for display on the first region of the active region prior to the refresh rate for image (411) and the refresh rate for image (411), a difference between a refresh rate for image (412) and the refresh rate for image (416), and a difference between a refresh rate for image (413) and the refresh rate for image (417) while images (411), (416), (417), (414), and (415) are maintained on the active region.

[0084] As a non-limiting example, requesting data (461) may be performed via a first interface (241) within the porch portion of the vertical synchronization signal. As a non-limiting example, requesting data (461) may be performed via a third interface (243). As a non-limiting example, requesting data (461) may also be performed via a second interface (242). For example, requesting data (461) may be performed to reduce afterimages and / or flickering that may occur on the first region of the active area, the second region of the active area, and the third region of the active area. As a non-limiting example, data (461) may be requested to at least one processor (210) for repeated display of image (411), image (416), and image (417).

[0085] For example, the request may include changing the state of a signal (e.g., the TE signal) transmitted from the display driving circuit (231) to at least one processor (210) via the second interface (242). For example, the display driving circuit (231) may change the state of the signal from a first state to a second state, such as state (451), for the request.

[0086] For example, at least one processor (210) may receive the request from the display driving circuit (231). For example, at least one processor (210) may generate (or obtain) an image (418) while the image (411), the image (416), the image (417), the image (414), and the image (415) are maintained on the active area. For example, at least one processor (210) may generate (or obtain) a command (305-5) for multi-frequency driving based on receiving the request and generating the image (418). As a non-limiting example, the command (305-5) may indicate where the images (e.g., the image (411), the image (416), the image (417), and the image (418)) to be transmitted from the at least one processor (210) are to be displayed. For example, the command (305-5) may indicate the display position of one or more images (e.g., image (411), image (416), and image (417)) generated by at least one processor (210) as well as the display position of one or more images (e.g., image (418)) generated by at least one processor (210) according to the request from the display driving circuit (231). For example, at least one processor (210) may transmit the command (305-5) to the display driving circuit (231) via the first interface (241). For example, the display driving circuit (231) may receive the command (305-5) from at least one processor (210).

[0087] For example, at least one processor (210) can transmit, to the display driving circuit (231), a VSS packet (304-8) via the first interface (241) to indicate a start time (444) of a vertical synchronization signal for displaying images (411), (416), (417), and (418) (e.g., corresponding to a start time of one of the start times of the light-emitting sections (390) capable of executing image transmission). For example, the VSS packet (304-8) can be transmitted for display on a portion of the active area (e.g., display on the first area, the second area, the third area, and the fifth area), unlike the VSS packet (304-6) which is transmitted for display on the active area. For example, the VSS packet (304-8) can be transmitted for changing an image displayed on a portion of the active area. For example, the display driver circuit (231) may change the state of the signal from the second state to the first state, such as state (452), based on (or in response to) a VSS packet (304-8) received from at least one processor (210). For example, the change from the second state to the first state may be performed for one or more images (e.g., image (411), image (416), image (417), and image (418)) to be received after the VSS packet (304-8).

[0088] For example, at least one processor (210), after transmitting the VSS packet (304-8), may transmit data including an image (411) to be re-displayed on the first area of ​​the active area, an image (416) to be re-displayed on the second area of ​​the active area, an image (417) to be re-displayed on the third area of ​​the active area, and an image (418) to be displayed on the fifth area of ​​the active area, to the display driving circuit (231) via the first interface (241). For example, the image (411) may be transmitted for a time length corresponding to the first area of ​​the active area, the image (416) may be transmitted for a time length corresponding to the second area of ​​the active area, the image (417) may be transmitted for a time length corresponding to the third area of ​​the active area, and the image (418) may be transmitted for a time length corresponding to the fifth area of ​​the active area. For example, at least one processor (210) can support multi-frequency driving of the display (230) by transmitting image (411), image (416), image (417), and image (418) and not transmitting an image to be displayed on the fourth region of the active area.

[0089] For example, the display driving circuit (231) can perform repeated display of an image (411) on the first area of ​​the active area, repeated display of an image (416) on the second area of ​​the active area, repeated display of an image (417) on the third area of ​​the active area, and repeated display of an image (418) on the fifth area of ​​the active area, while the image (414) is maintained on the fourth area of ​​the active area, using the data received from at least one processor (210) via the first interface (241). As a non-limiting example, the display driving circuit (231) may recognize that the data received from at least one processor (210) is to be used to perform the repeated display on the first area of ​​the active area, the repeated display on the second area of ​​the active area, and the repeated display on the third area of ​​the active area by performing a CRC (cyclic redundancy check) on the data, and based on the recognition, may perform the repeated display on the first area of ​​the active area, the repeated display on the second area of ​​the active area, and the repeated display on the third area of ​​the active area. For example, the display driving circuit (231) can perform a scan based on a start time (444) using the image (411), the image (416), the image (417), and the image (418), thereby performing the repeated display of the image (411) on the first area of ​​the active area, the repeated display of the image (416) on the second area of ​​the active area, the repeated display of the image (417) on the third area of ​​the active area, and the display of the image (418) on the fifth area of ​​the active area.

[0090] As described above, the electronic device (100) may perform multi-frequency driving of the display (230) by including at least one processor (210) that transmits one or more images and one or more additionally (or newly) generated images to the display driving circuit (231) based on the request transmitted from the display driving circuit (231) to reduce the afterimage and / or the flicker.

[0091] The above-exemplified operations may also be executed by the electronic device (501) illustrated in the description of FIGS. 5 and 6.

[0092] FIG. 5 is a block diagram of an electronic device (501) within a network environment (500) according to various embodiments. Referring to FIG. 5, in the network environment (500), the electronic device (501) may communicate with the electronic device (502) via a first network (598) (e.g., a short-range wireless communication network), or may communicate with at least one of the electronic device (504) or the server (508) via a second network (599) (e.g., a long-range wireless communication network). In one embodiment, the electronic device (501) may communicate with the electronic device (504) via the server (508). According to one embodiment, the electronic device (501) may include a processor (520), a memory (530), an input module (550), an audio output module (555), a display module (560), an audio module (570), a sensor module (576), an interface (577), a connection terminal (578), a haptic module (579), a camera module (580), a power management module (588), a battery (589), a communication module (590), a subscriber identification module (596), or an antenna module (597). In some embodiments, the electronic device (501) may omit at least one of these components (e.g., the connection terminal (578)), or may have one or more other components added. In some embodiments, some of these components (e.g., the sensor module (576), the camera module (580), or the antenna module (597)) may be integrated into one component (e.g., the display module (560)).

[0093] The processor (520) may, for example, execute software (e.g., a program (540)) to control at least one other component (e.g., a hardware or software component) of the electronic device (501) connected to the processor (520) and perform various data processing or operations. According to one embodiment, as at least a part of the data processing or operations, the processor (520) may store commands or data received from other components (e.g., a sensor module (576) or a communication module (590)) in a volatile memory (532), process the commands or data stored in the volatile memory (532), and store result data in a non-volatile memory (534). According to one embodiment, the processor (520) may include a main processor (521) (e.g., a central processing unit or an application processor) or an auxiliary processor (523) (e.g., a graphics processing unit, a neural processing unit (NPU), an image signal processor, a sensor hub processor, or a communication processor) that can operate independently or together with the main processor (521). For example, when the electronic device (501) includes the main processor (521) and the auxiliary processor (523), the auxiliary processor (523) may be configured to use less power than the main processor (521) or to be specialized for a given function. The auxiliary processor (523) may be implemented separately from the main processor (521) or as a part thereof.

[0094] The auxiliary processor (523) may control at least a portion of functions or states associated with at least one component (e.g., a display module (560), a sensor module (576), or a communication module (590)) of the electronic device (501), for example, on behalf of the main processor (521) while the main processor (521) is in an inactive (e.g., sleep) state, or together with the main processor (521) while the main processor (521) is in an active (e.g., application execution) state. In one embodiment, the auxiliary processor (523) (e.g., an image signal processor or a communication processor) may be implemented as a part of another functionally related component (e.g., a camera module (580) or a communication module (590)). In one embodiment, the auxiliary processor (523) (e.g., a neural network processing unit) may include a hardware structure specialized for processing artificial intelligence models. The artificial intelligence models may be generated through machine learning. This learning can be performed, for example, on the electronic device (501) itself where the artificial intelligence model is executed, or can be performed through a separate server (e.g., server (508)). The learning algorithm can include, for example, supervised learning, unsupervised learning, semi-supervised learning, or reinforcement learning, but is not limited to the examples described above. The artificial intelligence model can include multiple artificial neural network layers.The artificial neural network may be one of a deep neural network (DNN), a convolutional neural network (CNN), a recurrent neural network (RNN), a restricted Boltzmann machine (RBM), a deep belief network (DBN), a bidirectional recurrent deep neural network (BRDNN), a deep Q-network, or a combination of two or more of the above, but is not limited to the examples described above. In addition to, or alternatively to, a hardware structure, an artificial intelligence model may include a software structure.

[0095] The memory (530) can store various data used by at least one component (e.g., the processor (520) or the sensor module (576)) of the electronic device (501). The data can include, for example, software (e.g., the program (540)) and input data or output data for commands related thereto. The memory (530) can include a volatile memory (532) or a non-volatile memory (534).

[0096] The program (540) may be stored as software in the memory (530) and may include, for example, an operating system (542), middleware (544), or an application (546).

[0097] The input module (550) can receive commands or data to be used in a component of the electronic device (501) (e.g., a processor (520)) from an external source (e.g., a user) of the electronic device (501).
