1 shows exemplary components of an electronic device according to one embodiment.

Referring to FIG. 1, the electronic device 101 includes the electronic device 1801 shown in FIG. 18, the electronic device 2000 shown in FIGS. 20A to 20D, and the electronic device shown in FIGS. 21A and 21B. It may be implemented as a device 2000.

The electronic device 101 may include a processor 120, a display driving circuit 130, and a display 140.

In one embodiment, processor 120 may include processor 1820 shown in FIG. 18 . The processor 120 may be operatively or operably coupled with or connected with the display driving circuit 130.

In one embodiment, the display driving circuit 130 may include the display driving circuit 1930 shown in FIG. 19 . The display driving circuit 130 may be operatively coupled or connected to the display 140 .

In one embodiment, display 140 may include display 1910 shown in FIG. 19 . The display 140 may be at least partially inserted into the housing of the electronic device 101. For example, display 140 may be a display that is at least partially rollable into the housing. The display 140 may be at least partially extracted from the housing. For example, the display 140 may be at least partially exposed outside the housing. For example, the display 140 may include a display region that is at least partially exposed outside the housing. For example, display 140 may provide a plurality of states depending on the entry into or withdrawal from the housing. For example, the area of the display area may be different within each of the plurality of states. For example, the plurality of states provided by display 140 can be illustrated through FIG. 2. FIG. 2 shows an example of a change in the area of a display area of a display of an electronic device according to an embodiment.

Referring to FIG. 2, the display 140 is in one (a) state among the plurality of states, in which a part of the display 140 is exposed and another part of the display 140 is exposed to the first housing 201 and the other part. The first state 210 inserted into the first housing 201 of the second housing 202 can be provided. In one embodiment, the first state 210 may be a state that provides a viewable area with a minimum area (or size). In one embodiment, the first state 210 may be a state in which the display 140 provides a display area with a minimum area. Within the first state 210, the display area having the minimum area may be referred to as the first area 220. Within the first state 210, the area of the display 140 retracted into the first housing 201 may be referred to as the second area 230. Within the first state 210, the first area 220 may be a viewable area. In the first state 210, the first area 220 may be an area exposed outside the first housing 201. Within the first state 210, the second area 230 may be a non-viewable area by inserting into the first housing 201. Within the first state 210, the second area 230 may be an area covered with the first housing 201 by being drawn into the first housing 201. For convenience of explanation, this document assumes that the first housing 201 and the second housing 202 are made of an opaque material, making it impossible to see when the second area 230 is inserted into the first housing 201. However, this is only an example, and at least a portion of the first housing 201 and/or the second housing 202 may be made of a transparent material. In this case, even when the second area 230 is inserted into the first housing 201, at least a portion of the second area 230 may be visible through the first housing 201. In this case, the second area 230 may not be visible when the user looks directly at the first area 220.

The display 140 may provide a second state 250 in which the display 140 is maximally exposed, as another state among the plurality of states. In one embodiment, the second state 250 may be a state in which the display 140 provides a viewable area having the maximum area (or size). The second state 250 may be a state in which the display 140 provides a display area with the maximum area. Within the second state 250, the first area 220 and the second area 230 may be visible areas. In the second state 250, the first area 220 and the second area 230 may be areas exposed outside the first housing 201.

Although not shown in FIG. 2 , the display 140 may provide an intermediate state between the first state 210 and the second state 250 . The intermediate state may mean a state in which a portion of the first region 220 and the second region 230 is exposed and the remaining portion of the second region 230 is retracted into the first housing 201 . Within the intermediate state, the portions of the first area 220 and the second area 230 may be visible areas. In the intermediate state, the portions of the first area 220 and the second area 230 may be areas exposed outside the first housing 201 . In the intermediate state, the remaining portion of the second area 230 may be an area that is not visible due to being drawn into the first housing 201 . In the intermediate state, the remaining portion of the second area 230 may be a display area that is hidden by the first housing 201 by being drawn into the first housing 201 .

Figure 2 shows an example in which the second housing 202 is moved or slid in the first direction 235 to change from the first state 210 to the second state 250, but this is for convenience of explanation. will be. For example, depending on the implementation or design of the electronic device 101, the first housing 201 may be configured to move in a second direction opposite to the first direction 235 for transitioning from state 210 to state 250. It can also be moved or slid to (237).

Meanwhile, the direction in which the display area extends when changing from the first state 210 to the second state 250 and the direction in which the display area shrinks when changing from the second state 250 to the first state 210 The direction may vary depending on the type of electronic device 101. For example, in portrait mode, the electronic device 101 displays the display area extending in a first horizontal direction or contracting in a second horizontal direction opposite to the first horizontal direction. It can be implemented as an electronic device 260 that includes a display 140. For another example, the electronic device 101 extends vertically in both directions when changing from the first state 210 to the second state 250 in the portrait mode and changes to the second state 250. It may be implemented as an electronic device 270 including a display 140 that provides the display area that is vertically reduced in both directions when the first state 210 is changed. For another example, in the portrait mode, the electronic device 101 extends horizontally in both directions when changing from the first state 210 to the second state 250 and changes to the second state ( It may be implemented as an electronic device 280 including a display 140 that provides the display area that shrinks horizontally in both directions when changing from 250) to the first state 210. However, it is not limited to this.

Referring again to FIG. 1, the area of the display area of the display 140 exposed outside the housing may change when changing from one of the plurality of states to another state. For example, the change in the area may cause a change in the viewing angle of the peripheral portion or periphery part within the display area. This change in viewing angle can be illustrated through FIG. 3 . FIG. 3 shows an example of a change in viewing angle according to a change in the area of a display area of a display of an electronic device, according to an embodiment.

Referring to FIG. 3, the area of the display area in state 210 is the first edge 301 of the display area and the first edge of the display area substantially parallel to the first edge 301 of the display area. The distance between the two edges 302 may correspond to 2p. For example, a position ( Viewing angle when looking at the display area in state 210 from a position 304 spaced apart by a distance d from 303 Is It can be. Meanwhile, the area of the display area in state 250 is the first edge 311 of the display area and the second edge of the display area substantially parallel to the first edge 311 of the display area ( 312) can correspond to the distance 2q between them. For example, the distance 2q may be longer than the distance 2p. For example, a position ( Viewing angle when looking at the display area in state 250 from a position 314 spaced apart by a distance d from 313) is the viewing angle different from It can be. For example, the viewing angle within state 210 and viewing angle within 250 Since are different from each other, when state 210 is changed to state 250 or state 250 is changed to state 210, the peak wavelength of at least a portion of the light emitted from at least a portion of the display area is can be changed. For example, the change in the peak wavelength can be illustrated through FIG. 4. FIG. 4 is a graph showing a change in peak wavelength according to a change in the area of a display area of a display of an electronic device according to an embodiment.

Referring to FIG. 4, the horizontal axis of the graph 400 represents the ratio of extension of the display area, and the vertical axis of the graph 400 represents the change in the peak wavelength. The unit of the horizontal axis of the graph 400 is percent (%), and the unit of the vertical axis of the graph 400 is nanometer (nm). For example, the ratio of 0% may indicate the display area in the first state 210 and the ratio of 100% may indicate the display area in the second state 250.

For example, line 410 in graph 400 represents a change in the peak wavelength of red light emitted from at least a portion of the display area while the first state 210 is changed to the second state 250. , the line 420 in the graph 400 represents a change in the peak wavelength of green light emitted from at least a portion of the display area while the first state 210 is changed to the second state 250, and the graph ( A line 430 within 400 indicates a change in the peak wavelength of blue light emitted from at least a portion of the display area while the first state 210 is changed to the second state 250. For example, as shown through lines 410 and 420, a change in the peak wavelength of the red light may cause a change in the peak wavelength of the green light while the first state 210 changes to the second state 250. greater than the change in the peak wavelength. For example, as shown through lines 410 and 430, a change in the peak wavelength of the red light causes the blue light to change while the first state 210 changes to the second state 250. greater than the change in the peak wavelength of light. For example, as shown through lines 420 and 430, a change in the peak wavelength of the green light causes the blue light to change while the first state 210 changes to the second state 250. greater than the change in the peak wavelength of light. For example, since the change in the peak wavelength of the red light, the change in the peak wavelength of the green light, and the change in the peak wavelength of the blue light are different from each other, color deviation may occur depending on the change in the area of the display area. It can happen. For example, the color deviation can be illustrated through FIG. 5. FIG. 5 illustrates an example color deviation caused by a change in the area of a display area of a display of an electronic device according to an embodiment.

Referring to FIG. 5, when the area of the display area is expanded by extending the display area, the peak wavelength of the red light as shown through line 410, line 420, and line 430 Because the change is greater than the change in the peak wavelength of the green light and the change in the peak wavelength of the blue light, and the change in the peak wavelength of the green light is greater than the change in the peak wavelength of the blue light, the edge portion of the display area ( 500) and other edge portions 511 of the display area may appear bluish, resulting in color deviation. For example, the color deviation may occur due to a microcavity effect caused by a change in the position of the edge portion 511 as the display area extends.

Referring again to FIG. 1, the electronic device 101 may perform operations to prevent such color deviation from occurring.

For example, the display driving circuit 130 of the electronic device 101 may determine that the area of the display area of the display 140 exposed outside the housing of the electronic device 101 is smaller than that of the display 140 inside the housing. It can be identified that it changes depending on the insertion or withdrawal of the display 140 from the housing. For example, the identification may be performed based on sensing data obtained through a sensor (not shown in FIG. 1) within the electronic device 101. For example, the sensor can be used to identify the area of the display area. For example, the sensor may detect a change in the magnetic field due to the insertion of the display 140 into or the withdrawal of the display 140 from the housing, the insertion of the display 140 into the housing or the withdrawal of the display 140 from the housing. At least one sensor for sensing a change in light intensity due to the display 140 being pulled out, and/or a change in resistance due to the display 140 being drawn into or pulled out of the housing. may include. In one embodiment, the sensing data may be provided to the processor 120 from the sensor. The processor 120 may provide the display driving circuit 130 with data indicating the area of the display area based on the sensing data. The display driving circuit 130 may identify that the area of the display area is changed based on the data obtained from the processor 120. In one embodiment, the sensing data may be provided to the display driving circuit 130 directly from the sensor. The display driving circuit 130 may identify that the area of the display area is changed based on the sensing data. However, it is not limited to this.

For example, display drive circuit 130 may, in response to identifying that the area of the display area has changed, determine the peak wavelength of at least a portion of the light emitted from at least a portion of the display area having the changed area. You can obtain data to change . For example, the display driving circuit 130 may acquire the data to compensate for color deviation as shown through FIG. 5 caused by the change in the area of the display area. there is. For example, the data may be configured to increase or decrease the peak wavelength of at least a portion of light emitted from at least a portion of the display area to prevent the color deviation from occurring. For example, the data may be illustrated through FIG. 6. FIG. 6 illustrates an example of data for changing the peak wavelength of at least a portion of light emitted from at least a portion of the display area, according to an embodiment.

Referring to FIG. 6, the display driving circuit 130 uses the data in order to compensate for the color deviation caused within the edge portion 500 and the edge portion 511 of the display area shown in FIG. 5. Data 600 can be obtained. For example, the data 600 may have the color difference within a partial area 610 corresponding to an edge portion 500 of the display area and a partial area 620 corresponding to an edge portion 511 of the display area. It may be an image with a color to compensate for. For example, the color of the partial region 610 and partial region 620 in the image may be a yellow-based color. However, it is not limited to this.

Referring again to FIG. 1, the display driving circuit 130 may change the first image obtained from the processor 120 into a second image based on the data. For example, the first image may be frame data provided from the processor 120 to the display driving circuit 130. For example, when displaying the first image without changing it based on the data, color deviation as shown in FIG. 5 may occur, so the display driving circuit 130 displays the first image based on the data. Thus, the first image can be changed to the second image. In one embodiment, the display driving circuit 130 may obtain the second image by combining the data and the first image. For example, the second image, which is a composite of the data and the first image, may be illustrated in FIG. 7 . FIG. 7 illustrates an example method of acquiring an image based on data for changing the peak wavelength of at least a portion of light emitted from at least a portion of a display area, according to an embodiment.

Referring to FIG. 7, the display driving circuit 130 generates a second image 720 based on the first image 700 and data 600 in which color deviation as shown in FIG. 5 can be seen. can be obtained. For example, because the data 600 is configured to change the peak wavelength, the second image 720 presents a completely white image, unlike the first image 700, which appears as a white image with color deviation. can be provided. For example, in one embodiment, the display driving circuit 130 may obtain the second image 720 by combining the first image 700 and data 600. In one embodiment, the second image 720 may include multiple layers. For example, the second image 720 may include a first layer including the first image 700 and a second layer below or above the first layer including data 600. However, it is not limited to this.

Meanwhile, referring again to FIG. 1, the display driving circuit 130 may obtain the data for changing the peak wavelength based on the changed area of the display area. For example, the data may be obtained differently depending on the changed area.

In one embodiment, the display driving circuit 130 sets the peak wavelength of at least a portion of the light emitted from at least a portion of the display region having a minimum area (e.g., the display region in the first state 210). first reference data for setting and second reference data for setting a peak wavelength of at least a portion of light emitted from at least a portion of the display area having a maximum area (e.g., the display area in the second state 250) can be saved. For example, the first reference data and the second reference data may be stored in a non-volatile memory within the display driving circuit 130. For example, the display driving circuit 130 may acquire the data based on performing interpolation between the first reference data and the second reference data based on the changed area. For example, the implementation of the interpolation can be illustrated through FIG. 8. FIG. 8 illustrates an example method of obtaining data for changing the peak wavelength of at least a portion of light emitted from at least a portion of a display area, according to an embodiment.

Referring to FIG. 8, the horizontal axis of the graph 800 represents the area of the display area, and the vertical axis of the graph 800 represents the peak wavelength of at least a portion of light emitted from at least a portion of the display area. For example, when the value of the horizontal axis of the graph 800 is 0, the value 810 of the vertical axis of the graph 800 is the value 810 in the first state 210 that provides the display area with the minimum area. Indicates the value within the first reference data for setting the peak wavelength. For example, when the value of the horizontal axis of the graph 800 is a, the value 820 of the vertical axis of the graph 800 is the value 820 in the second state 250 that provides the display area with the maximum area. Indicates the value within the second reference data for setting the peak wavelength. In one embodiment, the display driving circuit 130 includes the first reference data including a value 810 based on the changed area of the display area, represented by value b on the horizontal axis of the graph 800, and By performing interpolation between the second reference data including value 820, the data including value 830 can be obtained. Since the data is obtained through the interpolation between the first reference data and the second reference data performed based on the changed area, the data compensates for color deviation caused when displaying the first image. It can be used to do this. For example, the electronic device 101 may prevent color deviation from occurring due to the change in the area of the display area by changing the first image to the second image based on the data. .

Referring again to FIG. 1, the display driving circuit 130 emits light from not only the first reference data and the second reference data, but also from at least a portion of the display area having an area between the minimum area and the maximum area. Third reference data for setting the peak wavelength of at least part of the light may be further stored. For example, the third reference data may be stored in the non-volatile memory within the display driving circuit 130 along with the first reference data and the second reference data. For example, the display driving circuit 130 performs interpolation between the first reference data and the third reference data or interpolation between the third reference data and the second reference data according to the changed area. By doing so, the data can be obtained. For example, the interpolation performed further based on the third reference data can be illustrated through FIG. 9 . FIG. 9 illustrates an example method of obtaining data for changing the peak wavelength of at least a portion of light emitted from at least a portion of a display area, according to an embodiment.

Referring to FIG. 9, the horizontal axis of the graph 900 represents the area of the display area, and the vertical axis of the graph 900 represents the peak wavelength of at least part of the light emitted from at least part of the display area. For example, when the value of the horizontal axis of the graph 900 is 0, the value 910 of the vertical axis of the graph 900 is the peak within the first state 210 that provides the display area with the minimum area. Indicates the value within the first reference data for setting the wavelength. For example, when the value of the horizontal axis of the graph 900 is a, the value 920 of the vertical axis of the graph 900 is the value 920 in the second state 250 that provides the display area with the maximum area. Indicates the value within the second reference data for setting the peak wavelength. For example, when the value of the horizontal axis of the graph 900 is b, the value 930 of the vertical axis of the graph 900 is a third state that provides the display area having an area between the minimum area and the maximum area ( Example: represents a value in the third reference data for setting the peak wavelength in an intermediate state between the first state 210 and the second state 250. In one embodiment, the display driving circuit 130 includes the first reference data including a value 910 based on the changed area of the display area, represented by value c on the horizontal axis of the graph 900, and By performing interpolation between the third reference data including the value 930, the data including the value 940 can be obtained. Since the data including the value 940 is obtained through the interpolation between the first reference data and the third reference data performed based on the changed area, the data including the value 940 , the peak wavelength can be set more precisely than data (e.g., data including the value 945) obtained through interpolation between the first reference data and the second reference data executed based on the changed area. . In one embodiment, the display driving circuit 130 includes the third reference data including a value 930 based on the changed area of the display area, represented by the value d on the horizontal axis of the graph 900, and By performing interpolation between the second reference data including the value 920, the data including the value 950 can be obtained. Since the data including the value 950 is obtained through the interpolation between the third reference data and the second reference data performed based on the changed area, the data including the value 950 , the peak wavelength can be set more precisely than data (e.g., data including the value 955) obtained through interpolation between the first reference data and the second reference data executed based on the changed area.

Figure 9 shows an example in which the display driving circuit 130 stores the first to third reference data, but this is for convenience of explanation. For example, the display driving circuit 130 may perform the interpolation illustrated through FIG. 9 further using reference data to set the peak wavelength within a state providing each of four or more areas, thereby providing more precise The peak wavelength can be set accordingly.

Meanwhile, referring again to FIG. 1, the display driving circuit 130 is configured to change the peak wavelength of at least some of the light emitted from at least a portion of the display area according to the speed at which the area of the display area changes. Based on data, it may be identified whether to change the first image to the second image (and/or obtain the data). For example, the display driving circuit 130 may identify whether the speed at which the area of the display area changes while the display area is extended or contracted is greater than or equal to a reference speed. For example, the reference speed may be used to identify whether to perform changing the first image to the second image (and/or acquiring the data) based on the data. 101). For example, the reference speed may be a parameter that is compared to the speed to identify whether color deviations that may result from displaying the first image while the area is changing are not visible. In one embodiment, display driving circuit 130 changes the first image to the second image based on the data, based on identifying that the speed is less than the reference speed, and replaces the second image with the second image. It can be displayed. In one embodiment, display driving circuit 130 may refrain from changing the first image to the second image based on the data, based on identifying that the speed is above the reference speed. ) can be postponed. For example, the display driving circuit 130 may display the first image instead of displaying the second image under the condition that the speed is greater than or equal to the reference speed. For example, because the speed being greater than the reference speed may mean that the color deviation caused while displaying the first image is not visible, the display driving circuit 130 bypasses acquiring the data. Based on this, the first image can be displayed through the display 140. For example, identifying whether to execute changing the first image to the second image according to the speed can be illustrated in FIG. 10. FIG. 10 illustrates an example method of adaptively displaying an image according to the speed at which the area of the display area changes, according to one embodiment.

Referring to FIG. 10, the display driving circuit 130 may identify the speed at which the area changes based on the sensing data obtained from the sensor through the processor 120 or directly from the sensor. . For example, the display driving circuit 130 may display the second image changed based on the data from the first image within a state 1000 in which the display area is extended at a speed less than the reference speed. You can. For another example, the display driving circuit 130 displays the second image changed based on the data from the first image in a state 1010 in which the display area is reduced at a speed less than the reference speed. can do. For another example, the display driving circuit 130 may display the first image in a state 1020 in which the display area is extended at a speed greater than the reference speed. For example, within state 1020, display driver circuit 130 may refrain from obtaining the data and/or changing the first image to the second image based on the data. . For another example, the display driving circuit 130 may display the first image in a state 1030 in which the display area is reduced at a speed greater than the reference speed. For example, within state 1030, display driver circuit 130 may refrain from obtaining the data and/or changing the first image to the second image based on the data. .

In one embodiment, under conditions where the speed is greater than the reference speed, such as state 1020 and state 1030, the display driving circuit 130 may identify whether the change in the area of the display area is stopped. there is. For example, display drive circuit 130 may maintain displaying the first image while identifying that the change in area is maintained. For example, the display driving circuit 130 may change the first image to the second image based on the data and display the second image, based on identifying that the change in the area has stopped. You can. The electronic device 101 according to an embodiment acquires the data under the condition that the speed at which the area changes is greater than the reference speed and/or converts the first image to the second image based on the data. By refraining from, postponing, or bypassing the change to , power consumption due to acquisition of the data and/or acquisition of the second image can be reduced.

Meanwhile, referring again to FIG. 1, in one embodiment, the display area, unlike the display area in FIG. 3 which includes only a planar portion, includes a planar portion or a planar part and a curved portion extending from the planar portion. It may include (curved portion or curved part). For example, an edge portion of the display area may be implemented as the curved portion. When the display area includes the curved portion, the viewing angle at the curved portion located at the edge portion may be different from the viewing angle at the flat portion. The difference between the viewing angle in the curved portion and the viewing angle in the flat portion can be illustrated through FIG. 11. FIG. 11 shows an example of a viewing angle in a curved portion of a display area of a display of an electronic device according to an embodiment.

Referring to FIG. 11, the display area may include a curved portion 1100 located at the edge portion. The viewing angle at a location 1110 located within the curved portion 1100 is the viewing angle at a location 1120 located within the planar portion 1115. Unlike, + It can be. As shown in FIG. 11, since the viewing angle of the curved portion and the viewing angle of the flat portion are different from each other, the degree to which the peak wavelength of light emitted from the curved portion changes according to the change in the area of the display area varies from the flat portion. The peak wavelength of the emitted light may be different from the degree to which it changes depending on the change in the area of the display area. For example, the extent to which the peak wavelength of light emitted from the curved portion changes according to a change in the area of the display area (e.g., a wavelength change rate of 10% or more) is determined by the peak wavelength of the light emitted from the flat portion of the display area. It may be greater than the degree of change depending on the change in area of the region.

Meanwhile, referring again to FIG. 1, the curved portion may be changed into a flat portion according to the withdrawal of the display 140 from the housing (or extension of the display area), and the flat portion may be converted to a flat portion into the display inside the housing. Depending on the insertion of 140 (or reduction of the display area), it may be changed to a curved portion. For example, referring to FIG. 11 , the curved portion 1100 may be changed into the flat portion by moving in the direction 1130 according to the extension of the display area. Since the peak wavelength of at least a portion of the light emitted from the curved portion is different from the peak wavelength of at least a portion of the light emitted from the flat portion, color deviation occurs when the curved portion is changed into the flat portion as the display area is extended. Alternatively, color deviation may occur when the flat portion is changed to the curved portion as the display area is reduced. For example, this color deviation can be illustrated through the description of FIG. 12. FIG. 12 illustrates an example color deviation caused by a change in the peak wavelength of light emitted from a curved portion of the display area according to a change in the area of the display area of a display of an electronic device, according to an embodiment.

Referring to FIG. 12, in state 1210, a partial area 1220 of the display area located at an edge of the display area may be a curved portion. The partial area 1220 of the display area may change from the curved part to the flat part according to the change from the state 1210 to the state 1250. For example, since the peak wavelength of at least some of the light emitted from the curved portion is different from the peak wavelength of at least some of the light emitted from the planar portion, within at least a portion of the partial region 1220 within state 1250 Color deviation may occur. For example, due to a difference between the peak wavelength of at least a portion of the light emitted from the curved portion and the peak wavelength of at least a portion of the light emitted from the planar portion, the partial region 1220 within the state 1250 becomes yellowish. Color deviation may appear (yellowish). However, it is not limited to this.

Referring back to Figure 1, in one embodiment, the display driving circuit 130 changes from the curved portion to a flat portion upon withdrawal of the display 140 from the housing to prevent such color deviation from occurring. Data for compensating for color deviation caused within a partial area within the display area may be obtained. For example, the data may be illustrated through the description of FIG. 13. FIG. 13 illustrates an example of data for changing the peak wavelength of at least a portion of light emitted from a portion of a display area changed from a curved portion to a flat portion, according to an embodiment.

Referring to FIG. 13, the display driving circuit 130 changes from the curved portion to the flat portion as the partial region 1220 changes from state 1210 to state 1250 based on the sensing data. can be identified. In response to the identification, the display driving circuit 130 may obtain data 1300 to prevent color deviation from occurring within at least a portion of the partial area 1220 shown in FIG. 12 . For example, the data 1300 may be an image having a color for compensating for the color deviation within the partial region 1320 corresponding to the partial region 1220. However, it is not limited to this.

Referring back to Figure 1, in one embodiment, the display driving circuit 130 changes the peak wavelength of at least a portion of the light emitted from a portion of the display area that has changed from a curved portion to a flat portion or from a flat portion to a curved portion. In order to obtain data for processing, interpolation similar to the above interpolation illustrated through the description of FIG. 8 or FIG. 9 may be performed. For example, the display driving circuit 130 may have a maximum area and reference data for setting the peak wavelength of at least a portion of light emitted from at least a portion of a curved portion located within an edge portion of the display area having a minimum area. The data may be obtained by performing interpolation between reference data for setting a peak wavelength of at least a portion of light emitted from at least a portion of a curved portion located within an edge portion within the display region based on the changed area of the display region. You can. For example, reference data for setting the peak wavelength of at least a portion of light emitted from at least a portion of a curved portion located within an edge portion of the display area having a minimum area and located within an edge portion of the display area having a maximum area. A method of acquiring the data through interpolation between reference data to set the peak wavelength of at least a portion of the light emitted from at least a portion of the curved portion may be illustrated in FIG. 14 . FIG. 14 illustrates an example method of obtaining data for changing the peak wavelength of at least a portion of light emitted from a portion of a display area changed from a curved portion to a flat portion, according to an embodiment.

Referring to FIG. 14, the display driving circuit 130 includes reference data 1400 for setting the peak wavelength of at least a portion of light emitted from at least a portion of a curved portion located within an edge portion of the display area having the minimum area. can be saved. For example, the display driving circuit 130 may store reference data 1410 for setting the peak wavelength of at least a portion of light emitted from at least a portion of a curved portion located within an edge portion of the display area having the maximum area. You can. For example, the reference data 1400 and 1410 may be stored in a non-volatile memory within the display driving circuit 130. For example, the display driving circuit 130 may obtain data 1300 based on performing interpolation between reference data 1400 and reference data 1410 based on the changed area. You can. For example, the display driving circuit 130 may obtain data 1300 by performing interpolation between reference data 1400 and reference data 1410 according to the method illustrated through the description of FIG. 8 or FIG. 9. You can. However, it is not limited to this.

The operations of the display driving circuit 130 illustrated through the description of FIGS. 13 and 14 are inextricably linked with the operations of the display driving circuit 130 illustrated through the description of FIGS. 6 to 9. ) is not. For example, the operations of the display driving circuit 130 illustrated through the description of FIGS. 13 and 14 can be combined with the operations of the display driving circuit 130 illustrated through the description of FIGS. 6 to 9 .

Referring again to FIG. 1, the display driving circuit 130 includes data for compensating for color deviation caused by the change in the area of the display area when the display area includes the curved portion and the curved surface. The first image may be changed to the second image based on other data for compensating for color deviation caused within the partial area changed from the partial to the flat portion. For example, a method of changing the first image to the second image based on the data and the other data may be illustrated in FIG. 15. FIG. 15 shows data for changing the peak wavelength of at least a portion of light emitted from a portion of the display area changed from a curved portion to a flat portion, according to an embodiment, and light emitted from at least a portion of the display area according to a change in the area of the display area. A method of acquiring an image based on data for changing the peak wavelength of at least some of the light is shown.

For example, data 600 is data for setting or changing the peak wavelength of at least a portion of light emitted from at least a part of the display area according to the change in the area of the display area, and data 1300 is a curved surface Since the second image 1550 is data for setting or changing the peak wavelength of at least part of the light emitted from at least part of the display area according to the change from part to planar part, the second image 1550 appears as a white image with color deviation. Unlike the first image 1500, which is gray, a completely white image can be provided. For example, in one embodiment, the display driving circuit 130 may obtain the second image 1550 by combining the first image 1500, data 600, and data 1300. In one embodiment, the second image 1550 may include a plurality of layers. For example, the second image 1550 may include a first layer including the first image 1500, a second layer including data 600, and a third layer including data 1300. You can. For example, the first layer may be placed on the second layer and the third layer, and the second layer may be placed on the third layer or below the third layer. For another example, the second layer may be placed on the first layer and the third layer, and the first layer may be placed on the third layer or below the third layer. For another example, the third layer may be placed on the first layer and the second layer, and the first layer may be placed on the second layer or below the second layer. However, it is not limited to this.

In one embodiment, the display driving circuit 130 may include components for executing the operations described above. For example, the components within the display driving circuit 130 can be illustrated through FIG. 16. FIG. 16 illustrates example components of a display driving circuit of an electronic device according to an embodiment.

Referring to FIG. 16, the display driving circuit 130 may include a compensation logic unit 1600 and a memory 1650.

For example, the compensation area identification unit 1610 may identify the changed area of the display area, the location of the flat portion within the display area, and the location of the curved portion within the display area, based on the sensing data. there is.

For example, the compensation logic unit 1600 may determine the data (e.g., data 600) and the other data (e.g., data 1300) based on the result of the identification of the compensation area identification unit 1610. It may include a compensation map processing unit 1620 to obtain . For example, the compensation map processing unit 1620 stores reference data 1660 in memory 1650 (e.g., the first reference data including the value 810, as illustrated through the description of FIG. 8 and Interpolation performed using the second reference data including value 820 and other reference data 1670 (e.g., reference data 1400 and reference data 1410, as illustrated throughout the description of FIG. 14 ) The data and the other data can be respectively obtained through interpolation performed using . In one embodiment, the memory 1650 may be distinguished from a memory in the display driving circuit 130 that is configured to at least temporarily store an image (eg, the first image 1500) obtained from the processor 120.

For example, as shown in FIG. 15, the image synthesis unit 1630 may obtain the second image 1550 by combining the first image 1500, data 600, and data 1300. . The second image 1550 acquired by the image synthesis unit 1630 may be displayed through the display 140.

FIG. 16 shows an example in which the compensation logic unit 1600 is included in the display driving circuit 130, but the compensation logic unit 1600 may also be included in the processor 120. In this case, the display driving circuit 130 may display the second image 1550 obtained from the compensation logic unit 1600 in the processor 120 through the display 140. However, it is not limited to this.

The above descriptions illustrate identifying a change in the area of the display area, but this is for convenience of explanation. For example, the processor 120 and/or the display driving circuit 130 in the electronic device 101 may detect a change in the length of one edge of the display area instead of identifying a change in the area of the display area. It can also be identified. For example, the processor 120 and/or the display driver circuit 130 in the electronic device 101 may detect a movement of a reference point within the display 140 instead of identifying a change in the area of the display area. It can also be identified. In other words, various methods for identifying the extent to which the display area is extended or contracted may be used within the electronic device 101 to prevent the color deviation from occurring.

Referring to FIG. 17, in operation 1702, the processor 120 displays the display 140 exposed outside the housing (e.g., the first housing 201 and the second housing 202) of the electronic device 101. It can be seen that the area of the display area changes depending on the insertion of the display 140 into the housing or the withdrawal of the display 140 from the housing. For example, the processor 120 may obtain sensing data through a sensor for identifying the area of the display area and identify that the area is changed based on the sensing data.

FIG. 17 shows an example in which the processor 120 identifies a change in the area of the display area, but this is for convenience of explanation.

For example, the data may be obtained based on the changed area. For example, the data may be obtained differently depending on the changed area. For example, the data may be obtained to compensate for color deviations caused by the change in the area. However, it is not limited to this.

In one embodiment, the processor 120 may obtain the data through interpolation of reference data. For example, the processor 120 may provide first reference data for setting a peak wavelength of at least a portion of light emitted from at least a portion of the display area (e.g., first state 210) having a minimum area and a maximum area. Performing interpolation between second reference data for setting a peak wavelength of at least a portion of light emitted from at least a portion of the display area (e.g., second state 250), based on the changed area. Based on this, the data can be obtained. However, it is not limited to this.

In operation 1706, the processor 120 may acquire an image based on the acquired data. For example, the processor 120 prevents color deviation from occurring due to a change in viewing angle due to a difference in size between the display area before the area is changed and the display area with the changed area, Based on the data, the image can be obtained.

In operation 1708, the processor 120 may display the image through the display 140. For example, the processor 120 may display the image through the display 140 based on providing the image as frame data to the display driving circuit 130.

Although not shown in FIG. 17, when the display area includes a curved portion located within an edge portion, the processor 120 determines the viewing angle at the curved portion and the flat portion of the display area extending from the curved portion. Operations can be performed to prevent color deviation from occurring due to differences in viewing angles.

For example, the display area before the area is changed may include a first partial region that is a flat portion and a second partial region that is the curved portion extending from the planar portion and located within the edge portion before the area is changed. may include. The processor 120 compensates for color deviations caused within the second partial area changed from the curved portion to the planar portion upon withdrawal of the display 140 from the housing (or upon extension of the display area). Other data can be obtained to do this. For example, the other data may be data for changing the peak wavelength of at least a portion of light emitted from at least a portion of the second partial region. For example, the processor 120 may acquire the image based on the data and other data. The processor 120 may display the image through the display 140 based on providing the acquired data to the display driving circuit 130.

In one embodiment, processor 120 may obtain the other data based on performing interpolation of reference data. For example, the processor 120 may provide first reference data for setting the peak wavelength of at least a portion of the light emitted from the curved portion of the display area having the minimum area and emit light from the curved portion of the display area having the maximum area. The other data may be obtained by performing interpolation between second reference data for setting the peak wavelength of at least a portion of the light based on the changed area.

Although not shown in FIG. 17, the processor 120 displays the image based on the data and/or other data according to the speed at which the area changes (e.g., the speed at which the display area is extended or reduced). You can identify whether to acquire or not. For example, the processor 120 may identify whether the speed is greater than or equal to the reference speed. For example, processor 120 obtains the data and/or other data while identifying that the speed is below the reference speed, and obtains the image based on the data and/or the other data. can do. For example, the processor 120 may display the image by providing the image to the display driving circuit 130. For example, processor 120 may, based on identifying that the speed is above the reference speed, refrain from, postpone or bypass obtaining the data and/or the other data, and Other images can be acquired without the use of data. For example, content included in the other image may correspond to content included in the image. For example, the processor 120 may display the other image by providing the other image to the display driving circuit 130. For example, because the speed is greater than the reference speed, color deviations that occur within the display area of display 140 may not be visible while the other image is displayed through display 140.

The above descriptions illustrate identifying a change in the area of the display area, but this is for convenience of explanation. For example, the processor 120 and/or the display driving circuit 130 in the electronic device 101 may detect a change in the length of one edge of the display area instead of identifying a change in the area of the display area. It can also be identified. For example, the processor 120 and/or the display driving circuit 130 in the electronic device 101 may detect a movement of a reference point within the display 140 instead of identifying a change in the area of the display area. It can also be identified. In other words, various methods for identifying the extent to which the display area is extended or contracted may be used within the electronic device 101 to prevent the color deviation from occurring.
