The operations of the modules described below are performed according to the execution of the modules (eg, the movement detection module 552, the movement control module 551, and the display control module 553) stored in the memory 550 (processor ( 540) can be understood as the operation. At least some of the modules (eg, the movement detection module 552, the movement control module 551, and the display control module 553) stored in the memory 550 are software, firmware, or a combination of at least two of them.

For example, the modules may be in the form of applications, programs, computer codes, instructions, routines, or processes executable by the processor 540. can be implemented as Accordingly, when the modules (eg, the movement detection module 552, the movement control module 551, and the display control module 553) are executed by the processor 540, the modules (eg, the movement detection module 553) The module 552, movement control module 551, and display control module 553 may cause the processor 540 to perform operations associated with the modules (or functions that the modules may provide). Therefore, description that a specific module performs an operation below may be interpreted as the processor 540 performing the corresponding operation as the specific module is executed. Alternatively, the modules (eg, the movement detection module 552, the movement control module 551, and the display control module 553) may be implemented as part of a specific application. Alternatively, without being limited to what has been described and/or shown, each module may be implemented as separate hardware (eg, a processor and a control circuit) from the processor 540 . Meanwhile, at least some of the operations of the modules described below may be implemented as separate modules instead of corresponding modules.

First, an example of an operation of the processor 540 based on the movement control module 551 according to various embodiments will be described below.

According to various embodiments, the movement control module 551 may control the display 530 (or the first structure 401 or the first plate 411a) of the electronic device 200 to slide. For example, the movement control module 551 may control the display 530 to slide by rotating the roller 451 in one direction by driving the aforementioned movement device 510 (eg, a motor). . For example, when the movement control module 551 rotates the roller 451 in a first direction (eg, counterclockwise), the display 530 slides out and moves, and the roller 451 ) is rotated in the second direction (eg, clockwise), the display 530 slides in and moves, and after rotating the roller 451 in the first direction, it rotates in the second direction In this case, the display 530 may slide-out and then slide-in. According to the control of the movement control module 551, the distance at which the display 530 slides (eg, slide-out movement or slide-in movement) may be limited (eg, about 40 mm). For example, the maximum distance for the slide-out movement is the distance at which the first structure 401 is maximally exposed to the outside through the second structure 202 in a state where the first structure 401 is accommodated in the second structure 202. , which may be determined by at least one of the width of the first structure 401 and the width of the second structure 202 . Also, for example, the maximum distance of the slide-in movement is when the first structure 401 is maximally exposed to the outside through the second structure 202, and the first structure 401 extends to the second structure. 202, which may also be determined by at least one of the width of the first structure 401 or the width of the second structure 202. For example, as at least one of the width of the first structure 401 or the width of the second structure 202 is longer, the first structure 401 slides (for example, slides out or slides in). When the first structure 401 is guided (or supported) by the inner lower surface of the second structure 202, it can slide a longer distance. The movement control module 551 may control the slide movement of the display 530 based on the occurrence of a specific event causing the slide movement. For example, the specific event identifies the execution and/or driving of the designated app, and a user's input (eg, identifying selection of an icon, physical key identifying the pressing of). At this time, the movement control module 551 can determine the distance to move the display 530, and the distance to be moved is a full extension distance (about 40 mm), an extension to a size to be displayed in a 16:9 aspect ratio, or a half extension ( eg 20 mm).

According to various embodiments, the movement control module 551 slides the display 530 (or the first structure 401, or the first plate 111a) at a designated speed (eg, slides out, slides). movement) can be controlled. For example, the movement control module 551 moves the display 530 at a speed (eg, 40 mm/sec) moving at a maximum distance (eg, about 40 mm) for a predetermined time (eg, 1 sec), The rotational speed of the motor can be controlled at a pre-set rotational speed. The rotational speed of the motor may be variable. For example, the movement control module 551 determines values of parameters associated with content processing (eg, processor 540 load, processor 540 usage (or usage rate), memory (RAM) usage (or usage ratio)) The rotational speed of the motor can be controlled with the rotational speed determined based on .

According to various embodiments, the movement control module 551 may provide a specific signal to the movement device 510 (eg, a motor) to drive the motor. For example, the movement control module 551 may provide a PWM signal. At this time, the movement control module 551 may control the rotational speed of the motor by controlling the characteristics (eg, frequency and/or magnitude) of the PWM signal provided to the moving device 510 (eg, the motor). . For example, the rotational speed of the motor may be proportional to the frequency and magnitude of the PWM signal. Referring to FIG. 6 , the movement control module 551 receives power for controlling (or driving) a motor received from the power management module 575 (e.g., peak power (or peak current, or peak voltage) that can be provided from a battery). )) may receive information about the size of the The movement control module 551 transmits a PWM signal having characteristics (eg, frequency and/or magnitude) corresponding to the magnitude of the power through a driver (eg, motor driver) of the mobile device 510 to the mobile device 510. (e.g. motor). For example, the movement control module 551 may provide a PWM signal having a high frequency and/or a high magnitude in proportion to the power to the movement device 510 (eg, a motor).

Hereinafter, an example of an operation of the processor 540 based on the movement detection module 552 according to various embodiments will be described with reference to FIG. 6 .

According to various embodiments, the movement detection module 552 may identify a parameter value associated with slide movement based on a value obtained from the sensor 520 . For example, the parameters include a state (moving state) of the electronic device 200 related to the slide movement (eg, closed state, slide movement start, slide movement in progress, slide movement completion), and exposure to the outside of the display 530. It may include parameters associated with the area that has been identified. The parameter associated with the area exposed to the outside of the display 530 is the area of the area exposed to the outside of the display 530 (exposure area), the area of the area drawn into the area compared to the area exposed to the outside of the display 530. It may include the area ratio (exposure ratio), and the distance that the display 530 is drawn out and/or drawn in (movement distance). For example, when a value is generated from the sensor 520 as the display 530 slides, the movement detection module 552 determines the movement state of the electronic device 200 (eg, closed state, sliding movement start, sliding movement in progress). , Slide movement completion) may be obtained. The movement detection module 552 can identify the value of the parameter corresponding to the obtained value. In addition, for example, when a value is generated from the sensor 520 as the display 530 slides, the movement detection module 552 determines the value of the parameter related to the area exposed to the outside of the display 530 corresponding to the generated value. value can be obtained.

According to various embodiments, the movement detection module 552 periodically transmits a signal S to another module (eg, the display control module 553) based on periodically identifying a value of a parameter associated with slide movement. can For example, referring to 601 of FIG. 6 , the movement detection module 552 determines a parameter associated with slide movement based on a value obtained from at least one sensor 520 at a designated period (eg, a sensing period, ts). value can be identified. Accordingly, the movement detection module 552 may transfer the signal S to another module (eg, the display control module 553) at a designated sensing period ts. The reciprocal number (1/ts) of the sensing period ts may be defined as sensing resolution, and the lower the sensing period ts, the higher the sensing resolution.

In one embodiment, the signal S may be an interrupt. The interrupt may indicate that a value of a parameter associated with slide movement (eg, a movement state, an exposure area, an exposure ratio, and a movement distance) is changed. The module (e.g., the display control module 553) that receives the interrupt identifies that a parameter associated with slide movement is changed, identifies the value of the changed parameter, and identifies the value of the changed parameter in the sensing period (ts) for receiving the interrupt. Based on the value, an operation may be performed (eg, re-drawing, re-sizing, and/or frame data generation described later). For example, if the parameter is the movement distance and the motor is maintained at a specific speed after the slide movement event occurs, the number of interrupts generated from the time the slide movement event occurs (n), withdrawal as shown in [Equation 1] below And/or the value of the movement distance may be determined based on the pull-in speed (vs) and the sensing period (ts).

In another embodiment, the signal (S) may include the value of the parameter associated with the slide movement. The module (e.g., the display control module 553) that receives the signal (S) periodically identifies the value of the parameter included in the received signal (S), and performs an operation based on the identified value ( Example: re-drawing, re-sizing, and/or frame data generation described later). In this case, the rotational speed of the motor and the speed of withdrawal and/or retraction of the display 530 can be varied while the slide movement is in progress, and the module (eg, the display control module 553 and) is expressed in [Equation 1] described above. It is possible to identify the value of the parameter included in the signal other than

Meanwhile, signals S on the time axis shown in 601 of FIG. 6 may be described on an axis representing a number (eg, a Number axis).

Hereinafter, an example of an operation of the display control module 553 according to various embodiments will be described.

According to various embodiments, the display control module 553 may control the display 530 to display an image. The image may be understood in terms of screen, content, and/or views by those skilled in the art. Referring to FIG. 6 , the display control module 553 periodically stores at least one piece of data (eg, first to third frame data) for displaying an image in the memory 620, and periodically stores it in the memory 620. At least one stored data (eg, first to third frame data) may be controlled to be transferred to the display driver IC 630 . The memory 620 may be a frame buffer, implemented inside the processor 540, separately implemented outside the processor 540, or a component related to the display 530 (e.g., the display driver IC 630). , may be implemented inside the display 530). Data stored in the memory 620 may be defined as frame data. The frame data may include information on coordinates for each pixel and information on a color value for each pixel (eg, a color value for R(red)-G(gree)-B(blue)). It is not limited to a bar and may be implemented to include more information. The display driver IC 630 may control the display 530 to display an image based on data received from the memory. The operation of controlling the display 530 of the display driver IC 630 controls a gate line and a source line to generate a light emitting device (eg, organic light emitting diode (O-LED), or It includes an operation of controlling a back-light device) to output light corresponding to a color value included in data, and since this is a well-known technique, a detailed description thereof will be omitted.

According to various embodiments, the display control module 553 controls the display 530 to display an image (or screen, content, or views) at a specific period (or updates an image displayed on the display 530). can do. In one embodiment, the display control module 553 may control the display 530 to display an image at a cycle corresponding to a refresh rate set in the electronic device 200 . For example, referring to FIG. 6 , the re-drawing module 553a requests renewal of data (eg, a view or screen) for displaying an image to the applications (Apps) 610 at a cycle corresponding to the refresh rate. and acquires data (eg, views or screens) according to the update request from the applications 610, and data for displaying an image (eg, views or screens) based on the acquired data (eg, views or screens). The aforementioned frame data) may be periodically generated. The re-drawing module 553a may generate frame data corresponding to an image (or screen) by merging data (eg, views or screens) obtained from the applications 610 . The display control module 553 may store the generated frame data in the memory 620 and transfer the frame data stored in the memory to the display driver IC 630 at a cycle corresponding to the refresh rate. In another embodiment, the re-drawing module 553a uses the sensor 520 to display an image with a sensing period ts (or sensing resolution) that identifies a value of a parameter associated with an area exposed to the outside. (530) can be controlled. For example, if the applications 610 are applications capable of updating data (eg, views or screens) based on parameters, the re-drawing module 553a, referring to FIG. Based on receiving a signal in one sensing period (ts), the application 610 may periodically transmit parameter values and request renewal of data (eg, a view or screen). The applications 610 may periodically return data (eg, views or screens) having size properties corresponding to parameter values. The re-drawing module 553a may generate frame data by merging data (eg, views or screens) and store the generated frame data in the memory 610 . Also, for example, if the applications 610 are not applications capable of updating data (eg, views or screens) based on parameters, the re-drawing module 553a determines that the area of the data corresponds to the value of the parameter. As described above, the display control module 553 transmits data stored in the memory 620 by the re-drawing module 553a at a sensing period ts. It can be transferred to the display driver IC 630. The operation of obtaining data for displaying an image based on the operation of the re-drawing module 553a of the above-described display control module 553 and storing the acquired data in the memory 620 is a re-drawing operation. can be defined The re-drawing operation based on the period corresponding to the scan rate of the display control module 553 and the re-drawing operation based on the sensing period ts may be performed in parallel with each other, but the period corresponding to the scan rate is not limited thereto. The display control module 553 may perform a re-drawing operation when the sensing period ts is set to be the same as . Meanwhile, for example, the display control module 553 may include a surface flinger and a graphic HAL.

According to various embodiments, the display control module 553 may perform new data (eg, previous frame data) for displaying an image based on pre-stored data (eg, previous frame data) in the memory 620 instead of the above-described re-drawing operation. : new frame data) can be created. For example, the frame generation module 553b generates new frame data based on the frame data stored in the memory 620 to display an image for each period corresponding to the sensing period ts, and generates the new frame data. may be stored in the memory 620. Frame data generated based on the frame data may be defined as virtual frame data. The operation of the frame generating module 553b may be defined as a frame generating operation. The display control module 553 may control the stored virtual frame data to be transferred to the display driver IC 630. The operation of the frame generating module 553b may be performed to prevent deterioration of image display quality of the display 530 due to delay in drawing in and/or a re-drawing operation when the display 530 is drawn in. 602 of FIG. 6 represents frame data generated based on a re-drawing operation after a slide movement event has occurred, as a comparative example. Referring to 602 of FIG. 6 , as completion of the re-drawing operation is delayed after the slide movement event occurs, generation of frame data and display of an image based on the frame data are delayed (eg, tL from the time corresponding to the sensing period). may be delayed). Therefore, as the image is not updated at the time of sensing the length, an image of an area smaller than the area of the area of the display 530 exposed to the outside is displayed, so that a portion of the area where the image of the display 530 is not displayed is displayed by the user. A black-out may occur, and display quality may deteriorate. The above delay may occur as a process for a re-drawing operation is delayed based on an increase in system load based on driving of a motor. 603 of FIG. 6 represents virtual frame data generated based on a frame generation operation after a slide movement event has occurred. Referring to 603 of FIG. 6 , after the slide movement event occurs, virtual frame data is generated at the right time based on the frame generation operation, and an image corresponding to the area of the area exposed to the outside is displayed at the right time. Quality can be guaranteed. An operation of generating frame data based on the frame generating module 553b and a mode of using the frame data will be described later in detail.

Hereinafter, an example of an operation of the electronic device 200 according to various embodiments will be described.

According to various embodiments, the electronic device 200 (eg, the processor 540) generates a second image based on a part of the first image displayed on the display 530 at a first point in time while the display 530 is drawn in or out. An image may be displayed at a second viewpoint following the first viewpoint. A time interval between the first time point and the second time point may be a sensing period (ts).

According to various embodiments, the operations illustrated in FIG. 7 may be performed in various orders without being limited to the illustrated order. Also, according to various embodiments, more operations than the operations illustrated in FIG. 7 may be performed, or at least one operation less than that shown in FIG. 7 may be performed. Hereinafter, FIG. 7 will be described with reference to FIG. 8 .

8 is a diagram for explaining an example of an operation of displaying a next image based on a part of a previous image with a length sensing period ts of the electronic device 200 according to various embodiments.

According to various embodiments, the electronic device 200 may display a first image on a first area of the flexible display 530 in operation 701 . For example, the electronic device 200 may display images 811a and 821a on areas exposed to the outside of the display 530 as shown in 801a and 801b of FIG. 8 . The area exposed to the outside may be the first area A1 in a closed state or an area exposed to the outside while the display 530 is drawn out and/or drawn in. The processor 540 (eg, the display control module 553) acquires the first frame data 811b and 821b at a specific time point corresponding to the sensing period ts (eg, the first time point t1), and The first frame data 811b and 821b stored in 610 (eg, a buffer memory) may be transferred to the display driver IC 630 . The first frame data 811b and 821b may include information about coordinates of each pixel and information about a color value of each pixel. The number of pixels of the first frame data 811b and 821b may correspond to the area of the first region exposed to the outside of the display 530 at a specific time point (eg, the first time point t1). The display driver IC 630 may display the first images 811a and 821a on the display 530 based on the first frame data 811b and 821b. Since the operation of the display control module 553 is the same as described in FIGS. 5 and 6, a detailed description thereof will be omitted.

According to various embodiments, the electronic device 200 determines whether the stored second area is exposed in operation 703, and if it is determined that the second area is exposed, the electronic device 200 displays the first area of the flexible display 530 in operation 705. A second image based on a part of the first image may be displayed on the third area including the first area and the second area. For example, referring to FIG. 8 , an area accommodated inside the display 530 of the electronic device 200 is exposed to the outside over time based on the driving of the mobile device 510 (eg, a motor), The area of the region exposed to the outside of the display 530 may be expanded. As shown in 802b and 803b of FIG. 8 , the processor 540 (eg, the display control module 553) displays an image displayed at a previous time point for each time point corresponding to the sensing period ts after the first time point t1. Images 822a and 823a based on portions 821c and 822c of 821a and 822a may be displayed. For example, the processor 540 displays the second image 822a at the second time point t2 based on the part 821b of the first image 821a displayed at the first time point t1, and displays the second image 822a at the second time point t1. The second image 822c may be displayed at the third time point t3 based on the part 822c of the first image 822a displayed at (t2). Portions 821c, 822c of the image (eg, first image 821a or second image 822a) are displayed 530 on the image (eg, first image 821a or second image 822a). ) may be an area within a specified range from the boundary of the expansion direction (eg, the last y-axis pixel in the expansion direction). As described above with reference to FIG. 3 , the extension direction is the direction in which a part of the display 530 (or the first plate or the first structure) is moved or the area of the display 530 stored from a specific part of the display 530. It can be defined as the direction to the part exposed to the outside. Alternatively, the extension direction may be defined as a direction. Also, the designated range may be determined according to the expansion speed of the display 530 and/or the sensing period ts, which will be described later with reference to FIGS. 11 and 12 . For example, referring to 802b and 803b of FIG. 8 , the images 822a and 823a displayed on the display 530 at a specific point in time are the images 821a and 822a displayed at a previous point in time and a part 821c of the image. , 822c).

According to various embodiments, the electronic device 200 (eg, the processor 540) performs an operation of displaying an image of a view next to a specific view based on a part of an image of a specific view for each sensing period ts. The display quality of images can be guaranteed. For example, 802a and 803a of FIG. 8 are frame data 812b and 813b generated based on a re-drawing operation of the processor 540 and images based on the frame data 812b and 813b as a comparison example ( An example of the display 530 on which 811a and 812b) are displayed is shown. Referring to 802a and 803a of FIG. 8 , as the re-drawing operation of the processor 540 (eg, the display control module 553) is delayed while the display 530 is extended, the corresponding sensing period ts The frame data 812b and 813b may be generated (ie, the display of an image having an area corresponding to the changed area of the display 530 may be delayed) at a later time point than the time points. Accordingly, the processor 540 (eg, the display control module 553) may display an image of a previous view on an area exposed to the outside of the display 530 at a time corresponding to the sensing period. Since the area of the image from the previous view is smaller than the area of the area exposed to the outside from the current view, the images 811a and 812a may be displayed on a part of the display 530, but the image may not be displayed on the other part. The remaining part of the area where the image of the area exposed to the outside of the display 530 is not displayed by the user is viewed as black (B), and thus image display quality may be degraded. According to various embodiments, the processor 540 generates virtual frame data 822b and 823b based on the frame data 821b and 822b of a previous view, thereby corresponding to the changed area of the display 530. The display of the images 822b and 823b having an area equal to or less than 822b and 823b is not delayed, and thus image display quality can be guaranteed.

According to various embodiments, when it is determined that the second area is not exposed, the electronic device 200 may continuously display the first image on the first area of the display 530 .

Meanwhile, although the drawing operation of the display 530 of the electronic device 200 has been described as an example, an image may be displayed based on a part of an image of a previous view even in the case of a pulling operation. For example, the electronic device 200 may display an image including a part other than a part of the image of this view at the next view. The part of the excluded image may be an area within a specified range from a boundary in a direction opposite to a reduction direction on the image.

Hereinafter, an example of an operation of the electronic device 200 according to various embodiments will be described.

According to various embodiments, the electronic device 200 (eg, the processor 540) displays a previous image pre-stored in the memory 610 (eg, a buffer memory) while the display 530 is drawn or drawn. Second data for displaying the current image may be generated based on the first data (eg, frame data) for processing. As the electronic device 200 performs an operation of generating data stored in the memory 610, an image having an area corresponding to the changed area of the display 530 is displayed while the display 530 is drawn or drawn. There is no delay, so image display quality can be guaranteed.

For example, the processor 540 (eg, the display control module 553) may transfer the first frame data stored in the memory 610 to the display driver IC 630 at a first point in time. The display driver IC 630 may control an image to be displayed on the display 530 based on data. Since the operation of the display control module 553 has been described above with reference to FIGS. 5 and 6 , a detailed description thereof will be omitted.

According to various embodiments, the electronic device 200 determines whether the stored second area is exposed in operation 903, and when it is determined that the second area is exposed, in operation 905, the electronic device 200 determines whether the second area is exposed. Based on the second frame data, a second screen including a first screen and a part of the first screen may be displayed. For example, the processor 540 (eg, the display control module 553) displays second frame data generated based on first frame data pre-stored in the memory 610 at a second time point after the first time point. It can be transmitted to the driver IC 630. The second frame data may be transferred to the display driver IC 630 after being stored in the memory 610, or directly transferred to the display driver IC 630 without being stored in the memory 610. For example, the processor 540 may generate frame data corresponding to an increase in the area of the area exposed to the outside of the display 530 at a second time point based on a portion of the first frame data at the first time point. . Examples of the generating operation will be described later with reference to FIGS. 10A, 10B, and 10C. In addition, the execution timing of the operation of generating the second frame data may be determined according to a mode associated with generating the frame data of the electronic device 200, which will be described later with reference to FIGS. 14 to 19 . Having received the second frame data, the display driver IC 630 can control display of the second image on the display 530 based on the second frame data. Hereinafter, examples of an operation of generating second frame data based on first frame data of the electronic device 200 (eg, the processor 540) will be described.

The size (or the number of pixels) of the portion 1011a of the first frame data may be as large as the size corresponding to the increase in the area of the area exposed to the outside of the display 530 . In the electronic device 200, mapping information on the number of pixels and physical area (or physical length (eg, the length of drawing out and/or entering/output of the display 530)) is stored in advance, and the electronic device 200 ( Example: The processor 540 may identify a portion of the frame data 1011a having a size equal to the number of pixels corresponding to an increase in physical area (or an increase in length) based on the mapping information. As part of the operation of acquiring the part of the first frame data, the electronic device 200 identifies the position of the part of the frame data to be obtained based on the expansion direction, and determines the size (or section) of the part of the frame data to be obtained. can be identified, which will be described later in FIGS. 11 and 12. The electronic device 200 arranges the first frame data 1011 obtained from the origin (0,0) of pixel coordinates, and arranges the first frame data 1011 from the end (eg, X,0) of the extension direction of the arranged first frame data. By arranging part 1011a of one frame data, second frame data 1012 can be generated.

Second frame data 1022 including the frame data 1022a may be generated. For example, the electronic device 200 arranges all of the first frame data 1021 pre-stored in the memory 610 from the origin (0,0), and expands the first frame data 1021 to the first frame data 1021. Third frame data 1022a having a color value determined based on the color value of the first frame data 1021 from the end of (eg, (X,0)) to a designated part (eg, (X1,0)) of can be placed. The position and length (X1-X) of the third frame data 1022a are extended as the position and length of the part 1011a of the first frame data to be copied are identified in 1001 of FIG. 10A. Since it may be determined based on the direction, the sensing period (ts), and/or the expansion speed, a detailed description thereof will be omitted. For example, the electronic device 200 may determine an average value of color values of the first frame data 1021 as a color value of the third frame data 1022a. As another example, the electronic device 200 may determine the primary color value of the first frame data 1021 as the color value of the third frame data 1022a. The primary color value may be defined as an average of values of the largest number of color types among color types.
