[0029] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

[0030] Figure 1 is a view schematically showing a configuration of a display device 100 according to an embodiment of the present disclosure, Figure 2 It is schematically shown Figure 1 A plan view of the display panel, and Figure 3 is shown in the settings Figure 2 A magnified view of pixels in area A.

[0031] Reference Figures 1 to 3 , the display device 100 according to an embodiment of the present disclosure includes a display panel 110 , an optical module 120 , a panel driving unit 130 , an optical driving unit 140 , a controller 150 , and a memory 160 .

[0032] The display panel 110 includes a plurality of pixels and displays a color image. The display panel 110 may be implemented using an organic light emitting display panel, a liquid crystal display panel, a plasma display panel, a quantum dot light emitting display panel, or an electrophoretic display panel.

[0033] The display panel 110 may be divided into a display area DA where pixels are formed to display an image and a non-display area NDA where no image is displayed.

[0034] The non-display area NDA may be provided to surround the display area DA. A panel driving unit 130 supplying various kinds of signals to a plurality of signal lines in the display area DA and a link unit (not shown) configured to connect the panel driving unit 130 and the plurality of signal lines to each other may be formed in the non-display area NDA.

[0035] In the display area DA, a plurality of pixels are arranged to display an image. Figure 2 As shown in FIG, the display area DA includes a first display area DA1 and a second display area DA2.

[0036] The first display area DA1 is an area that does not overlap with the area CA in which the optical module 120 is disposed, and displays an image regardless of the operation of the optical module 120. The first display area DA1 may be formed to have a large size.

[0037] A plurality of first pixels P1, each of which includes at least two first sub-pixels SP1, may be disposed in the first display area DA1. Each of the plurality of first pixels P1 may include a light-emitting pixel. Specifically, each of the at least two first sub-pixels SP1 included in each first pixel P1 may be a light-emitting sub-pixel including a light-emitting device that emits light of a predetermined color. Each first pixel P1 may include at least two of a red sub-pixel configured to emit red light, a green sub-pixel configured to emit green light, and a blue sub-pixel configured to emit blue light. As an example, one of the first pixels P1 may include a red sub-pixel and a green sub-pixel, and an adjacent one of the first pixels P1 may include a blue sub-pixel and a green sub-pixel. As another example, each first pixel P1 may include a red sub-pixel, a green sub-pixel, and a blue sub-pixel.

[0038] The second display area DA2 overlaps with the area CA in which the optical module 120 is disposed, and an image to be displayed in the second display area DA2 may be determined according to whether the optical module 120 is operated. Specifically, when the optical module 120 is not operated, the second display area DA2 may display an image together with the first display area DA1. On the other hand, when the optical module 120 is operated, the second display area DA2 may not display an image or may display a black image. At this time, an image may be displayed in the first display area DA1.

[0039] The size, position, and shape of the second display area DA2 may be determined in consideration of the optical module 120. The second display area DA2 may be disposed at a position corresponding to the optical module 120. In addition, the second display area DA2 may be disposed to have a size including the area CA in which the optical module 120 is disposed.

[0040] A plurality of second pixels P2, each including at least two second sub-pixels SP2, may be disposed in the second display area DA2. In the second display area DA2, unlike the first display area DA1, the plurality of second pixels P2 may include light-emitting pixels and non-light-emitting pixels. Each light-emitting pixel may be a region including a light-emitting device for emitting light, and each non-light-emitting pixel may be a region that does not include a light-emitting device and transmits external light. That is, unlike the first display area DA1, a region that does not include a light-emitting device and transmits external light may be disposed in the second display area DA2.

[0041] Each of the at least two second sub-pixels SP2 included in each luminescent pixel among the second pixel P2 may be a luminescent sub-pixel including a light-emitting device that emits light of a predetermined color. Each luminescent pixel among the second pixel P2 may include at least two of a red sub-pixel configured to emit red light, a green sub-pixel configured to emit green light, and a blue sub-pixel configured to emit blue light. As an example, one of the luminescent pixels among the second pixel P2 may include a red sub-pixel and a green sub-pixel, and an adjacent one of the luminescent pixels among the second pixel P2 may include a blue sub-pixel and a green sub-pixel. As another example, each luminescent pixel among the second pixel P2 may include a red sub-pixel, a green sub-pixel, and a blue sub-pixel.

[0042] Each of the at least two second sub-pixels SP2 included in each non-light emitting pixel among the second pixels P2 may be a non-light emitting sub-pixel that includes a non-light emitting device and transmits external light.

[0043] As a result, the number of light-emitting sub-pixels disposed in the unit pixel area UPA of the second display area DA2 may be smaller than the number of light-emitting sub-pixels disposed in the unit pixel area UPA of the first display area DA1. Figure 3 As shown in , 4 light emitting sub-pixels may be disposed in the unit pixel area UPA of the second display area DA2 , and 16 light emitting sub-pixels may be disposed in the unit pixel area UPA of the first display area DA1 .

[0044] The transmittance of the second display area DA2 may be changed according to the number of light-emitting sub-pixels arranged in its unit pixel area UPA. In the case where the number of light-emitting sub-pixels arranged in the unit pixel area UPA increases, the brightness and resolution of the second display area DA2 may increase, while the transmittance of the second display area DA2 may decrease. On the other hand, in the case where the number of light-emitting sub-pixels arranged in the unit pixel area UPA decreases, the brightness and resolution of the second display area DA2 may decrease, while the transmittance of the second display area DA2 may increase. In the display panel 110 according to an embodiment of the present disclosure, the number of light-emitting sub-pixels may be determined in consideration of the brightness, resolution, and transmittance of the second display area DA2.

[0045] The transmittance and resolution of the first display area DA1 and the second display area DA2 described above may be different from each other. The first display area DA1 may have a first transmittance, and the second display area DA2 may have a second transmittance higher than the first transmittance. In addition, the first display area DA1 may have a first resolution, and the second display area DA2 may have a second resolution lower than the first resolution.

[0046] The optical module 120 may be disposed at the rear surface of the display panel 110. The optical module 120 may be disposed to overlap with the display area DA (especially the second display area DA2) of the display panel 110. The optical module 120 may include all components configured to use external light input through the display panel 110. For example, the optical module 120 may be a camera. However, the present disclosure is not limited thereto. The optical module 120 may be an ambient light sensor or a fingerprint sensor.

[0047] The panel driving unit 130 controls driving of the display panel 110 based on a control signal received from the controller 150. To this end, the panel driving unit 130 includes a gate driving unit and a data driving unit.

[0048] The gate driving unit generates a gate signal for driving a gate line of the display panel 110 in response to a gate control signal received from the controller 150. The gate driving unit supplies the generated gate signal to subpixels SP1 and SP2 of pixels P1 and P2 included in the display panel 110 via the gate line.

[0049] The data driving unit receives a data control signal and an image data signal from the controller 150. The data driving unit converts the digital image data signal into an analog image data signal in response to the data control signal received from the controller 150. The data driving unit supplies the converted image data signal to the sub-pixels SP1 and SP2 of the pixels P1 and P2 included in the display panel 110 via the data lines.

[0050] The optical driving unit 140 controls driving of the optical module 120 based on a control signal received from the controller 150 .

[0051] The memory 160 stores shape information of the second display area DA2. The shape information of the second display area DA2 includes position information indicating a start point of a boundary of the second display area, vertical length information of the second display area, and line-based direction information and width information.

[0052] The controller 150 uses the shape information of the second display area DA2 stored in the memory 160 to change the image displayed in at least one of the first display area DA1 and the second display area DA2 of the display panel 110. Specifically, the controller 150 may generate display area information and boundary information of each of a plurality of pixels using the shape information of the second display area DA2. The controller 150 may change the image displayed on the display panel 110 using at least one of the display area information and the boundary information of each of the plurality of pixels, and may perform control so that the corrected image is displayed on the display panel 110.

[0053] In the following, reference will be made to Figures 4 to 12 The shape information of the second display area DA2 stored in the memory 160 and the information generated by the controller 150 are described in more detail.

[0054] Figure 4 is a view showing the configuration of a memory and a controller. Figure 5A is a view illustrating a start point and a vertical length and direction information of a second display area when the second display area has a U-shape, Figure 5B is a view illustrating a start point and a vertical length and direction information of a second display area when the second display area has a circular shape, and Figure 6 is a view illustrating left boundary information and right boundary information. Figure 7is a view showing an example of a second display area having a U-shape, and Figure 8 It shows Figure 7 FIG. 4 is a view showing an example of shape information of the second display area. Fig. 9 is a view illustrating an edge region, and Fig.10 is a view showing an example of display area information of each of a plurality of sub-pixels. Fig.11 is a view showing an example of a boundary area and boundary information of each of a plurality of pixels, and Fig.12 is a view showing an example of a kernel.

[0055] Reference Figures 4 to 12 The memory 160 stores the shape information of the second display area DA2. The controller 150 changes an image displayed in at least one of the first display area DA1 and the second display area DA2 of the display panel 110 using the shape information of the second display area DA2 stored in the memory 160.

[0056] The shape information of the second display area DA2 may include position information of the starting point, vertical length information of the second display area DA2, left boundary information related to the left boundary located on the left side of the center axis C based on the second display area DA2, and right boundary information related to the right boundary located on the right side of the center axis C based on the second display area DA2.

[0057] The position information of the starting point may include an X-axis coordinate value and a Y-axis coordinate value at a specific point of the boundary of the second display area DA2. According to the shape of the second display area DA2, one or more starting points may be included.

[0058] As an example, Figure 5A As shown in , the second display area DA2 may have a U-shape. In the case where the second display area DA2 has a U-shape, a plurality of starting points may be set. The starting points may include a first starting point S1 located on the left side of the central axis C and a second starting point S2 located on the right side of the central axis C.

[0059] The position information of the first starting point S1 may include an X-axis value notch_s1x of the first starting point S1 and a Y-axis value notch_sy of the first starting point S1. The position information of the second starting point S2 may include an X-axis value notch_s2x of the second starting point S2 and a Y-axis value notch_sy of the second starting point S2. The Y-axis value of the first starting point S1 and the Y-axis value of the second starting point S2 may be the same as each other, and the X-axis value of the first starting point S1 and the X-axis value of the second starting point S2 may be different from each other. However, the present disclosure is not limited thereto. Both the Y-axis value and the X-axis value of the first starting point S1 and the second starting point S2 may be different from each other.

[0060] As another example, Figure 5B As shown in , the second display area DA2 may have a circular shape. In the case where the second display area DA2 has a circular shape, a single starting point may be set. The starting point may include a third starting point S3 located at the center axis C. The position information of the third starting point S3 may include an X-axis value circle_sx of the third starting point S3 and a Y-axis value circle_sy of the third starting point S3.

[0061] The vertical length information of the second display area DA2 may include the vertical length of the shape of the second display area DA2. The vertical length of the shape of the second display area DA2 may correspond to the difference between the minimum Y-axis value and the maximum Y-axis value among the coordinate values ​​of the plurality of points constituting the boundary of the second display area DA2. At this time, the Y-axis value of the starting point may be the minimum Y-axis value or the maximum Y-axis value.

[0062] As an example, in Figure 5A In the case where the second display area DA2 has a U-shape as shown in , the vertical length information of the second display area DA2 may include a maximum value notch_hei among vertical lengths between a plurality of points constituting the boundary of the second display area DA2 and the first starting point S1.

[0063] As another example, in Figure 5B In the case where the second display area DA2 has a circular shape as shown in , the vertical length information of the second display area DA2 may include a maximum value circle_hei among vertical lengths between a plurality of points constituting the boundary of the second display area DA2 and the third starting point S3.

[0064] The left boundary information, which is information about the left boundary located on the left side based on the central axis C of the second display area DA2, includes direction information and width information of each of a plurality of lines set within a vertical length from a starting point.

[0065] The left boundary information may include the direction information and width information of each of the first line to the nth line at the starting point. At this time, n may correspond to the vertical length of the second display area DA2. For example, the vertical length of the second display area DA2 may be 20, in which case the left boundary information may include the direction information and width information of each of the first line to the 20th line at the starting point.

[0066] The direction information included in the left boundary information may indicate a direction in which the left boundary located on the left side based on the central axis C of the second display area DA2 moves from the first line to the n-th line.

[0067] Specifically, in the case where the distance between the central axis C and the left boundary set at the previous line is equal to or less than the distance between the central axis C and the left boundary set at the relevant line, the direction information included in the left boundary information may have a first direction value. That is, in the case where the left boundary is parallel to the central axis C or becomes away from the central axis C, the direction information included in the left boundary information may have a first direction value.

[0068] For example, in Figure 5A In the case where the left boundary is parallel to the central axis C as shown in , the direction information included in the left boundary information may have a first direction value of 0. Alternatively, in the case where Figure 5B In the case where the left boundary shown in becomes distant from the central axis C, the direction information included in the left boundary information may have a first direction value of 0.

[0069] In the case where the distance between the central axis C and the left boundary set at the previous line is greater than the distance between the central axis C and the left boundary set at the relevant line, the direction information included in the left boundary information may have a second direction value. That is, in the case where the left boundary becomes close to the central axis C, the direction information included in the left boundary information may have a second direction value.

[0070] For example, in Figure 5A and Figure 5B In the case where the left boundary shown in becomes close to the central axis C, the direction information included in the left boundary information may have a second direction value of 1.

[0071] The width information included in the left boundary information may include the width of the left boundary at each of the first line to the nth line. At this time, the width may correspond to the number of pixels or sub-pixels set in the relevant line. The width of the left boundary at each of the first line to the nth line may be sequentially stored as the width information included in the left boundary information.

[0072] The right boundary information, which is information about the right boundary located on the right side based on the central axis C of the second display area DA2, includes direction information and width information of each of a plurality of lines set within a vertical length from a starting point.

[0073] The right boundary information may include direction information and width information of each of the first to n-th lines where the starting point is located. At this time, n may correspond to the vertical length of the second display area DA2.

[0074] The direction information included in the right boundary information may indicate a direction in which the right boundary located on the right side based on the central axis C of the second display area DA2 moves from the first line to the n-th line.

[0075] Specifically, in the case where the distance between the central axis C and the right boundary set at the previous line is equal to or less than the distance between the central axis C and the right boundary set at the relevant line, the direction information included in the right boundary information may have a first direction value. That is, in the case where the right boundary is parallel to the central axis C or becomes away from the central axis C, the direction information included in the right boundary information may have a first direction value.

[0076] For example, in Figure 5A In the case where the right boundary shown in FIG. 1 is parallel to the central axis C, the direction information included in the right boundary information may have a first direction value of 0. Alternatively, in the case where Figure 5B In the case where the right boundary shown in becomes away from the central axis C, the direction information included in the right boundary information may have a first direction value of 0.

[0077] In the case where the distance between the central axis C and the right boundary set at the previous line is greater than the distance between the central axis C and the right boundary set at the relevant line, the direction information included in the right boundary information may have a second direction value. That is, in the case where the right boundary becomes close to the central axis C, the direction information included in the right boundary information may have a second direction value.

[0078] For example, in Figure 5A and Figure 5B In the case where the right boundary shown in becomes close to the central axis C, the direction information included in the right boundary information may have a second direction value of 1.

[0079] The width information included in the right boundary information may include the width of the right boundary at each of the first line to the nth line. At this time, the width may correspond to the number of pixels or sub-pixels set in the relevant line. The width of the right boundary at each of the first line to the nth line may be sequentially stored as the width information included in the right boundary information.

[0080] Figure 5A and Figure 5B It is illustrated that the first direction value is 0 and the second direction value is 1. However, the present disclosure is not limited thereto. In another embodiment, the first direction value may be 1 and the second direction value may be 0.

[0081] The left and right boundary information can be Figure 6 While the structure shown in is stored in the memory 160, for example, the left boundary information and the right boundary information of each of the six lines can be stored as 8 bytes.

[0082] The direction information of each of the three consecutive lines can be stored as 1 byte. For example, in 1 byte among 8 bytes, the direction information line1 ld of the left boundary at the first line, the direction information line1 rd of the right boundary at the first line, the direction information line2 ld of the left boundary at the second line, the direction information line2 rd of the right boundary at the second line, the direction information line3 ld of the left boundary at the third line, and the direction information line3 rd of the right boundary at the third line can each be stored in sequence as 1 bit.

[0083] The width information of each of the three consecutive lines can be stored in 3 bytes. For example, in 3 bytes among the 8 bytes, the width information of the left border at the first line, the width information of the right border at the first line, the width information of the left border at the second line, the width information of the right border at the second line, the width information of the left border at the third line, and the width information of the right border at the third line can each be stored in 4 bits in sequence.

[0084] The direction information of each of the three lines after the previously stored line can be stored by 1 byte. For example, in 1 byte among 8 bytes, the direction information line4 1d of the left boundary at the fourth line, the direction information line4 rd of the right boundary at the fourth line, the direction information line5 1d of the left boundary at the fifth line, the direction information line5 rd of the right boundary at the fifth line, the direction information line6 1d of the left boundary at the sixth line, and the direction information line6 rd of the right boundary at the sixth line can each be stored by 1 bit.

[0085] The width information of each of the three lines after the previously stored line may be stored in 3 bytes. For example, in 3 bytes among the 8 bytes, the width information of the left border at the fourth line, the width information of the right border at the fourth line, the width information of the left border at the fifth line, the width information of the right border at the fifth line, the width information of the left border at the sixth line, and the width information of the right border at the sixth line may each be stored in 4 bits.

[0086] In the following, reference will be made to Figure 7 and Figure 8 Specific examples of the left boundary information and the right boundary information are described.

[0087] The second display area DA2 may have a U-shape, such as Figure 7 In this case, the starting point may include a first starting point S1 located on the left side of the central axis C and a second starting point S2 located on the right side of the central axis C.

[0088] Figure 7The shape information of the second display area DA2 shown in FIG. 4 may include direction information and width information of each of the first to n-th lines where the starting points S1 and S2 are located.

[0089] Since the left boundary at the first line line1 where the starting points S1 and S2 are located becomes close to the center axis C, the direction information of the left boundary at the first line line1 may have a second direction value, for example, 1. In addition, since the right boundary at the first line line1 becomes close to the center axis C, the direction information of the right boundary at the first line line1 may have a second direction value, for example, 1.

[0090] The width information of the left border at the first line line1 may indicate a horizontal distance between a leftmost border pixel of the first line line1 and a leftmost border pixel of a second line line2 located next to the first line line1. Since the horizontal distance between the leftmost border pixel of the first line line1 and the leftmost border pixel of the second line line2 corresponds to six pixels, the width information of the left border at the first line line1 may be 6.

[0091] The width information of the right boundary at the first line line1 may indicate a horizontal distance between the rightmost boundary pixel of the first line line1 and the rightmost boundary pixel of the second line line2 located next to the first line line1. Since the horizontal distance between the rightmost boundary pixel of the first line line1 and the rightmost boundary pixel of the second line line2 corresponds to five pixels, the width information of the right boundary at the first line line1 may be 5.

[0092] Based on the width information and direction information of the first line line1, it can be seen that the leftmost boundary pixel of the second line line2 is set at a position of the second line line2 that is six pixels shifted from the leftmost boundary pixel of the first line line1 toward the center axis C. In addition, it can be seen that the rightmost boundary pixel of the second line line2 is set at a position of the second line line2 that is five pixels shifted from the rightmost boundary pixel of the first line line1 toward the center axis C.

[0093] Since the left boundary at the second line line2 becomes close to the center axis C, the direction information of the left boundary at the second line line2 may have a second direction value of, for example, 1. In addition, since the right boundary at the second line line2 becomes close to the center axis C, the direction information of the right boundary at the second line line2 may have a second direction value of, for example, 1.

[0094] The width information of the left border at the second line line2 may indicate a horizontal distance between the leftmost border pixel of the second line line2 and the leftmost border pixel of the third line line3 located next to the second line line2. Since the horizontal distance between the leftmost border pixel of the second line line2 and the leftmost border pixel of the third line line3 corresponds to four pixels, the width information of the left border at the second line line2 may be 4.

[0095] The width information of the right boundary at the second line line2 may indicate a horizontal distance between the rightmost boundary pixel of the second line line2 and the rightmost boundary pixel of the third line line3 located next to the second line line2. Since the horizontal distance between the rightmost boundary pixel of the second line line2 and the rightmost boundary pixel of the third line line3 corresponds to three pixels, the width information of the right boundary at the second line line2 may be 3.

[0096] Based on the width information and direction information of the second line line2, it can be seen that the leftmost boundary pixel of the third line line3 is set at a position of the third line line3 that is moved four pixels from the leftmost boundary pixel of the second line line2 toward the center axis C. In addition, it can be seen that the rightmost boundary pixel of the third line line3 is set at a position of the third line line3 that is moved three pixels from the rightmost boundary pixel of the second line line2 toward the center axis C.

[0097] The direction information and width information of each of the third line line3 to the sixth line line6 may be set in the same manner as the direction information and width information described above. In an embodiment, when the distance between the boundary at the relevant line and the central axis C is equal to the distance between the boundary at the next line and the central axis C, the width information may be set to 0. For example, Figure 7 As shown in , the distance between the leftmost boundary pixel of the sixth line line6 and the central axis C may be equal to the distance between the leftmost boundary pixel of the seventh line line7 and the central axis C. In this case, since the horizontal distance between the leftmost boundary pixel of the seventh line line7 and the leftmost boundary pixel of the sixth line line6 is 0, the width information of the left boundary at the sixth line line6 may be set to 0.

[0098] The display device 100 according to the embodiment of the present disclosure may sequentially store the direction information and width information of each of the first to n-th lines in the order of lines in the memory 160. Since the direction information and width information of each of the first to n-th lines are sequentially stored in the order of lines, the display device 100 according to the embodiment of the present disclosure can easily acquire the boundary of the second display area based on only the position information and vertical length information of the starting point of the second display area and the direction information and width information of the lines.

[0099] Therefore, the display device 100 according to the embodiment of the present disclosure can minimize the amount of information stored in the memory 160, thereby using a small-capacity memory 160. In addition, the display device 100 according to the embodiment of the present disclosure can obtain the boundary of the second display area DA2 through simple calculation, thereby reducing the amount of calculation in the process of independently controlling the first display area DA1 and the second display area DA2.

[0100] In addition, in the display device 100 according to the embodiment of the present disclosure, it is sufficient to change only the shape information of the second display area DA2 stored in the memory 160, whereby the shape of the second display area DA2 can be easily changed.

[0101] Return to reference Figure 4 , the controller 150 generates display area information and boundary information using the shape information of the second display area DA2 stored in the memory 160. The controller 150 may correct an image displayed in at least one of the first display area DA1 and the second display area DA2 of the display panel 110 using the display area information and the boundary information, and may perform control so that the corrected image is displayed on the display panel 110.

[0102] To this end, the controller 150 may include a line counting unit 310 , a boundary pixel extraction unit 330 , a display area information generation unit 340 , a boundary information generation unit 350 , an image processing unit 360 , and a control unit 370 .

[0103] The line counting unit 310 may count line values ​​from the first line of the display panel 110 in which the plurality of pixels P are arranged one by one, and may provide the counted line values ​​to the boundary pixel extraction unit 330. The line counting unit 310 may determine whether the counted line values ​​correspond to the first line where the starting point is located using the position information of the starting point stored in the memory 160. When the line counting unit 310 determines that the counted line values ​​correspond to the first line where the starting point is located, the boundary pixel extraction unit 330 may retrieve the shape information of the second display area DA2 from the memory 160.

[0104] The boundary pixel extraction unit 330 may extract the leftmost boundary pixel and the rightmost boundary pixel from the relevant line using the position information of the starting point, the line-based direction information, and the width information stored in the memory 160. Here, the relevant line may be a line corresponding to the line value provided by the line counting unit 310. The leftmost boundary pixel may be a pixel disposed at the leftmost side of the relevant line among the second pixels P2 disposed in the second display area DA2. The rightmost boundary pixel may be a pixel disposed at the rightmost side of the relevant line among the second pixels P2 disposed in the second display area DA2.

[0105] The boundary pixel extraction unit 330 may extract the leftmost boundary pixel and the rightmost boundary pixel of each of the first line to the nth line where the starting point is located in the order of lines. The boundary pixel extraction unit 330 may extract the leftmost boundary pixel and the rightmost boundary pixel of the relevant line using the leftmost boundary pixel and the rightmost boundary pixel of the previous line, the direction information of the previous line, and the width information of the previous line.

[0106] Specifically, the line value corresponding to the first line where the starting point is located from the line counting unit 310 may be input to the boundary pixel extraction unit 330. Fig. 9 As shown in FIG. 1 , the boundary pixel extraction unit 330 may extract the leftmost boundary pixel BP1 and the rightmost boundary pixel BP2 of the first line using the position information of the starting point.

[0107] At this time, in the case where the second display area DA2 has a U-shape, the pixel disposed at a position corresponding to the first starting point S1 may be the leftmost boundary pixel BP1, and the pixel disposed at a position corresponding to the second starting point S2 may be the rightmost boundary pixel BP2. In addition, in the case where the second display area DA2 has a circular shape, Fig. 9 Unlike what is shown in FIG. 1 , the pixels disposed at the position corresponding to the starting point may be the leftmost boundary pixel BP1 and the rightmost boundary pixel BP2.

[0108] The line value corresponding to the second line disposed next to the first line from the line counting unit 310 may be input to the boundary pixel extraction unit 330. The boundary pixel extraction unit 330 may extract the leftmost boundary pixel BP3 and the rightmost boundary pixel BP4 of the second line using the leftmost boundary pixel BP1 and the rightmost boundary pixel BP2 of the first line, the direction information of the first line, and the width information of the first line.

[0109] In the case where the direction information of the left boundary of the first line has the first direction value, the leftmost boundary pixel BP3 of the second line may be a pixel disposed at a position of the second line moved from the leftmost boundary pixel BP1 of the first line in a direction opposite to the central axis C by a number corresponding to the width information of the left boundary of the first line. The Y-axis value of the leftmost boundary pixel BP3 of the second line may have a value higher by 1 than the Y-axis value of the leftmost boundary pixel BP1 of the first line, and the X-axis value of the leftmost boundary pixel BP3 of the second line may have a value obtained by subtracting a value corresponding to the width information of the left boundary of the first line from the X-axis value of the leftmost boundary pixel BP1 of the first line.

[0110] In the case where the direction information of the left boundary of the first line has the second direction value, the leftmost boundary pixel BP3 of the second line may be a pixel disposed at a position of the second line moved from the leftmost boundary pixel BP1 of the first line toward the central axis C by a number corresponding to the width information of the left boundary of the first line. The Y-axis value of the leftmost boundary pixel BP3 of the second line may have a value higher by 1 than the Y-axis value of the leftmost boundary pixel BP1 of the first line, and the X-axis value of the leftmost boundary pixel BP3 of the second line may have a value obtained by adding a value corresponding to the width information of the left boundary of the first line to the X-axis value of the leftmost boundary pixel BP1 of the first line.

[0111] In addition, in the case where the direction information of the right boundary of the first line has the first direction value, the rightmost boundary pixel BP4 of the second line may be a pixel disposed at a position of the second line moved from the rightmost boundary pixel BP2 of the first line in the direction opposite to the central axis C by the number corresponding to the width information of the right boundary of the first line. The Y-axis value of the rightmost boundary pixel BP4 of the second line may have a value higher by 1 than the Y-axis value of the rightmost boundary pixel BP2 of the first line, and the X-axis value of the rightmost boundary pixel BP4 of the second line may have a value obtained by adding the value corresponding to the width information of the right boundary of the first line to the X-axis value of the rightmost boundary pixel BP2 of the first line. In the case where the direction information of the right boundary of the first line has the second direction value, the rightmost boundary pixel BP4 of the second line may be a pixel disposed at a position of the second line moved from the rightmost boundary pixel BP2 of the first line toward the central axis C by the number corresponding to the width information of the right boundary of the first line. The Y-axis value of the rightmost boundary pixel BP4 of the second line may have a value that is 1 higher than the Y-axis value of the rightmost boundary pixel BP2 of the first line, and the X-axis value of the rightmost boundary pixel BP4 of the second line may have a value obtained by subtracting a value corresponding to the width information of the right boundary of the first line from the X-axis value of the rightmost boundary pixel BP2 of the first line.

[0112] As described above, the boundary pixel extraction unit 330 may extract the leftmost boundary pixel and the rightmost boundary pixel of each of the first to nth lines.

[0113] The display area information generating unit 340 may generate display area information of each of the plurality of pixels P using the leftmost boundary pixel and the rightmost boundary pixel of each line.

[0114] The display area information generation unit 340 may decide the leftmost boundary pixel, the rightmost boundary pixel, and the pixel disposed between the leftmost boundary pixel and the rightmost boundary pixel among the pixels disposed in the relevant line as the second pixel P2 disposed in the second display area DA2. The display area information generation unit 340 may decide the pixels other than the leftmost boundary pixel, the rightmost boundary pixel, and the pixel disposed between the leftmost boundary pixel and the rightmost boundary pixel among the pixels disposed in the relevant line as the first pixel P1 disposed in the first display area DA1.

[0115] The display area information generating unit 340 may set the display area information of each first sub-pixel SP1 included in the first pixel P1 to the first display area value. For example, the first display area value may be 0, such as Fig.10 as shown in .

[0116] The display area information generating unit 340 may set the display area information of each second sub-pixel SP2 included in the second pixel P2 to the second display area value or the third display area value. The display area information generating unit 340 may generate the display area information in a state where the second pixel P2 disposed in the second display area DA2 is divided into an emitting pixel and a non-emitting pixel.

[0117] In the case where the second pixel P2 is a light-emitting pixel, the display area information generating unit 340 may set the display area information of each second sub-pixel SP2 included in the light-emitting pixel to the second display area value. For example, the second display area value may be 1, such as Fig.10 as shown in .

[0118] In addition, when the second pixel P2 is a non-luminescent pixel, the display area information generating unit 340 may set the display area information of each second sub-pixel SP2 included in the non-luminescent pixel to the third display area value. For example, the third display area value may be 2, such as Fig.10 as shown in .

[0119] Fig.10It is illustrated that the second display area DA2 is divided into luminous pixels and non-luminous pixels in units of pixels. However, the present disclosure is not limited to this. The second display area DA2 can be divided into luminous sub-pixels and non-luminous sub-pixels in units of sub-pixels. Specifically, the plurality of second sub-pixels SP2 included in one second pixel P2 can all be luminous sub-pixels or non-luminous sub-pixels. Alternatively, some of the plurality of second sub-pixels SP2 included in one second pixel P2 can be luminous sub-pixels, and other second sub-pixels SP2 of the plurality of second sub-pixels SP2 can be non-luminous sub-pixels.

[0120] The boundary information generating unit 350 may generate boundary information of pixels disposed in the boundary area BA located within a predetermined range from the boundary B between the first display area DA1 and the second display area DA2 using the leftmost boundary pixel and the rightmost boundary pixel of each line.

[0121] like Fig.11 As shown in , the border area BA may include a plurality of first border areas BA1 arranged in the first display area DA1. For example, the first border area BA1 may include a 1-1 border area BA1-1 arranged adjacent to the border B in the first display area DA1, a 1-2 border area BA1-2 arranged adjacent to the 1-1 border area BA1-1 in the first display area DA1, and a 1-3 border area BA1-3 arranged adjacent to the 1-2 border area BA1-2 in the first display area DA1. At this time, the distance between the 1-2 border area BA1-2 and the border B may be greater than the distance between the 1-1 border area BA1-1 and the border B, and the distance between the 1-3 border area BA1-3 and the border B may be greater than the distance between the 1-2 border area BA1-2 and the border B.

[0122] Fig.11 It is shown that the first display area DA1 includes three boundary areas BA1-1, BA1-2 and BA1-3. However, the present disclosure is not limited thereto. The first display area DA1 may include two boundary areas, or may include one boundary area. Alternatively, the first display area DA1 may include four or more boundary areas.

[0123] like Fig.11As shown in , the border area BA may include a plurality of second border areas BA2 arranged in the second display area DA2. For example, the second border area BA2 may include a 2-1 border area BA2-1 arranged in the second display area DA2 to be adjacent to the border B, a 2-2 border area BA2-2 arranged in the second display area DA2 to be adjacent to the 2-1 border area BA2-1, and a 2-3 border area BA2-3 arranged in the second display area DA2 to be adjacent to the 2-2 border area BA2-2. At this time, the distance between the 2-2 border area BA2-2 and the border B may be greater than the distance between the 2-1 border area BA2-1 and the border B, and the distance between the 2-3 border area BA2-3 and the border B may be greater than the distance between the 2-2 border area BA2-2 and the border B.

[0124] Fig.11 It is shown that the second display area DA2 includes three boundary areas BA2-1, BA2-2 and BA2-3. However, the present disclosure is not limited thereto. The second display area DA2 may include two boundary areas, or may include one boundary area. Alternatively, the second display area DA2 may include four or more boundary areas.

[0125] The boundary information generating unit 350 may generate boundary information of each pixel disposed in the boundary area BA using a kernel K consisting of m rows and m columns (m is a natural number greater than 2). Fig.11 and Fig.12 As shown in , the kernel K will be described as consisting of seven rows and seven columns. However, the present disclosure is not limited thereto. The size of the kernel K may vary.

[0126] Reference Fig.11 and Fig.12 , the boundary information generation unit 350 may set each of the plurality of pixels P at the center of the kernel K. The boundary information generation unit 350 may determine the boundary value of the pixel CP set at the center of the kernel K based on the position in the kernel K where the boundary pixel is set. Here, the boundary pixels, which are pixels set adjacent to the first display area DA1 in the second display area DA2, may include the leftmost boundary pixel and the rightmost boundary pixel of each line. In addition, the boundary pixels may include pixels set between the leftmost boundary pixel and the rightmost boundary pixel of each of the first to nth lines.

[0127] The boundary information generating unit 350 may set the pixel CP in the central area of ​​the kernel K, and may confirm the position in the kernel K where the boundary pixel is set.

[0128] In the case where the kernel K consists of seven rows and seven columns, the kernel K may include a central region (0,0) and eight first regions (-1,-1), (0,-1), (1,-1), (1,0), (1,1), (0,1), (-1,1), and (-1,0) disposed adjacent to the central region around the central region. In addition, the kernel K may include 16 second regions (-2,-2), (-1,-2), (0,-2), (1,-2), (2,-2), (2,-1), (2,0), (2,1), (2,2), (1,2), (0,2), (-1,2), (-2,2), (-2,1), (-2,0), and (-2,-1) disposed adjacent to the first region around the first region. In addition, the kernel K may include 24 third regions (-3, -3), (-2, -3), (-1, -3), (0, -3), (1, -3), (2, -3), (2, -3), (3, -3), (3, -2), (3, -1), (3, 0), (3, 1), (3, 2), (3, 3), (2, 3), (1, 3), (0, 3), (-1, 3), (-2, 3), (-3, 3), (-3, 2), (-3, 1), (-3, 0), (-3, -1) and (-3, -2).

[0129] The boundary information generation unit 350 may determine whether the pixel CP set in the central area of ​​the kernel K is the first pixel P1 set in the first display area DA1 or the second pixel P2 set in the second display area DA2. In the case where the pixel CP set in the central area of ​​the kernel K is the first pixel P1 and the boundary pixel is set in any one of the 24 third areas of the kernel K, the boundary information generation unit 350 may set a first boundary value for the pixel CP set in the central area of ​​the kernel K. For example, the first boundary value may be 1.

[0130] The boundary information generating unit 350 may set the boundary information of each first pixel P1 disposed in the 1-3 boundary area BA1-3 to have a first boundary value of 1, for example. Fig.11 as shown in .

[0131] In the case where the pixel CP disposed in the central area of ​​the kernel K is the first pixel P1 and the boundary pixel is disposed in any one of the 16 second areas of the kernel K, the boundary information generating unit 350 may set a second boundary value for the pixel CP disposed in the central area of ​​the kernel K. For example, the second boundary value may be 2.

[0132] The boundary information generating unit 350 may set the boundary information of each first pixel P1 disposed in the 1-2 boundary area BA1-2 to have a second boundary value of, for example, 2, such as Fig.11 as shown in .

[0133] In the case where the pixel CP disposed in the central area of ​​the kernel K is the first pixel P1 and the boundary pixel is disposed in any one of the eight first areas of the kernel K, the boundary information generating unit 350 may set a third boundary value for the pixel CP disposed in the central area of ​​the kernel K. For example, the third boundary value may be 3.

[0134] The boundary information generating unit 350 may set the boundary information of each first pixel P1 disposed in the 1-1 boundary area BA1-1 to have a third boundary value of, for example, 3, such as Fig.11 as shown in .

[0135] In addition, when the pixel CP set in the central area of ​​the kernel K is the second pixel P2 and the boundary pixel is set in any one of the 8 first areas of the kernel K, the boundary information generating unit 350 may set a fourth boundary value for the pixel CP set in the central area of ​​the kernel K. For example, the fourth boundary value may be 4.

[0136] The boundary information generating unit 350 may set the boundary information of each second pixel P2 disposed in the 2-1 boundary area BA2-1 to have a fourth boundary value of, for example, 4, such as Fig.11 as shown in .

[0137] In the case where the pixel CP disposed in the central area of ​​the kernel K is the second pixel P2 and the boundary pixel is disposed in any one of the 16 second areas of the kernel K, the boundary information generating unit 350 may set a fifth boundary value for the pixel CP disposed in the central area of ​​the kernel K. For example, the fifth boundary value may be 5.

[0138] The boundary information generating unit 350 may set the boundary information of each second pixel P2 disposed in the 2-2 boundary area BA2-2 to have a fifth boundary value of, for example, 5, such as: Fig.11 as shown in .

[0139] In the case where the pixel CP disposed in the central area of ​​the kernel K is the second pixel P2 and the boundary pixel is disposed in any one of the 24 third areas of the kernel K, the boundary information generating unit 350 may set a sixth boundary value for the pixel P disposed in the central area of ​​the kernel K. For example, the sixth boundary value may be 6.

[0140] The boundary information generating unit 350 may set the boundary information of each second pixel P2 disposed in the 2-3 boundary area BA2-3 to have a sixth boundary value of, for example, 6, such as Fig.11 as shown in .

[0141] As a result, each pixel P disposed in the boundary area BA may have a boundary value that increases or decreases as the distance from the boundary pixel increases. In an embodiment, each first pixel P1 disposed in the first display area DA1 among the pixels P disposed in the boundary area BA may have a boundary value that decreases as the distance from the boundary pixel increases. Each second pixel P2 disposed in the second display area DA2 among the pixels P disposed in the boundary area BA may have a boundary value that increases as the distance from the boundary pixel increases.

[0142] In addition, each of the first pixel P1 and the second pixel P2 disposed in the region other than the boundary region may be set to a seventh boundary value. For example, the seventh boundary value may be zero.

[0143] The image processing unit 360 changes the image displayed on the display panel 110 using the display area information generated by the display area information generating unit 340 and the boundary information generated by the boundary information generating unit 350. The image processing unit 360 may change the image displayed in the boundary area BA, and may perform control so that the corrected image is displayed on the display panel 110.

[0144] In the following, reference will be made to Figures 13 to 15 An example of the image processing unit 360 is described in more detail.

[0145] Fig.13 It shows Figure 4 A view of an example of a configuration of an image processing unit, Fig.14 is a view showing an example of adjusting the brightness of an image by an image processing unit, and Fig.15 is a view showing another example of adjusting the brightness of an image by the image processing unit.

[0146] Reference Figures 13 to 15 The image processing unit 360 may include an image receiving unit 361 , a region determining unit 362 , and a brightness adjusting unit 363 .

[0147] The image receiving unit 361 receives image data from an external system. At this time, the received image data may include image data of the first display area DA1 and the second display area DA2.

[0148] The area decision unit 362 decides the image data of the boundary area BA among the received image data. Specifically, the area decision unit 362 may decide the image data of the boundary area BA among the received image data based on the boundary information generated by the boundary information generation unit 350.

[0149] The area decision unit 362 may determine the image data of pixels P whose respective boundary information has a value corresponding to the boundary area BA as the image data of the boundary area BA. For example, the area decision unit 362 may determine the image data of pixels P whose respective boundary information has a boundary value greater than 0 as the image data of the boundary area BA.

[0150] The area decision unit 362 may decide image data of each of a plurality of boundary areas BA among the received image data. The boundary area BA may include a first boundary area BA1 disposed adjacent to the boundary B in the first display area DA1 and a second boundary area BA2 disposed adjacent to the boundary B in the second display area DA2.

[0151] The region decision unit 362 may determine the image data of each of the first boundary region BA1 and the second boundary region BA2. The region decision unit 362 may determine the image data of the first pixel P1 whose respective boundary information has a value corresponding to the first boundary region BA1 as the image data of the first boundary region BA1. The region decision unit 362 may determine the image data of the second pixel P2 whose respective boundary information has a value corresponding to the second boundary region BA2 as the image data of the second boundary region BA2.

[0152] In addition, a plurality of first border areas BA1 may be set. For example, the first border area BA1 may include a 1-1 border area BA1-1 disposed adjacent to the border B in the first display area DA1, a 1-2 border area BA1-2 disposed adjacent to the 1-1 border area BA1-1 in the first display area DA1, and a 1-3 border area BA1-3 disposed adjacent to the 1-2 border area BA1-2 in the first display area DA1.

[0153] The region decision unit 362 may determine the image data of each of the plurality of first boundary regions BA1-1, BA1-2, and BA1-3. The region decision unit 362 may determine the image data of the first pixel P1 whose respective boundary information has a value corresponding to the 1-1 boundary region BA1-1 as the image data of the 1-1 boundary region BA1-1. For example, the region decision unit 362 may determine the image data of the first pixel P1 whose respective boundary information has a third boundary value as the image data of the 1-1 boundary region BA1-1.

[0154] The region decision unit 362 may determine the image data of the first pixel P1 whose respective boundary information has a value corresponding to the 1-2 boundary region BA1-2 as the image data of the 1-2 boundary region BA1-2. For example, the region decision unit 362 may determine the image data of the first pixel P1 whose respective boundary information has a second boundary value as the image data of the 1-2 boundary region BA1-2.

[0155] The region decision unit 362 may determine the image data of the first pixel P1 whose respective boundary information has a value corresponding to the 1-3 boundary region BA1-3 as the image data of the 1-3 boundary region BA1-3. For example, the region decision unit 362 may determine the image data of the first pixel P1 whose respective boundary information has a first boundary value as the image data of the 1-3 boundary region BA1-3.

[0156] In addition, a plurality of second border areas BA2 may be set. For example, the second border area BA2 may include a 2-1 border area BA2-1 set adjacent to the border B in the second display area DA2, a 2-2 border area BA2-2 set adjacent to the 2-1 border area BA2-1 in the second display area DA2, and a 2-3 border area BA2-3 set adjacent to the 2-2 border area BA2-2 in the second display area DA2.

[0157] The region decision unit 362 may determine the image data of each of the plurality of second boundary regions BA2-1, BA2-2, and BA2-3. The region decision unit 362 may determine the image data of the second pixels P2 whose respective boundary information has a value corresponding to the 2-1 boundary region BA2-1 as the image data of the 2-1 boundary region BA2-1. For example, the region decision unit 362 may determine the image data of the second pixels P2 whose respective boundary information has a fourth boundary value as the image data of the 2-1 boundary region BA2-1.

[0158] The region decision unit 362 may determine the image data of the second pixel P2 whose respective boundary information has a value corresponding to the 2-2 boundary region BA2-2 as the image data of the 2-2 boundary region BA2-2. For example, the region decision unit 362 may determine the image data of the second pixel P2 whose respective boundary information has a fifth boundary value as the image data of the 2-2 boundary region BA2-2.

[0159] The region decision unit 362 may determine the image data of the second pixel P2 whose respective boundary information has a value corresponding to the 2-3 boundary region BA2-3 as the image data of the 2-3 boundary region BA2-3. For example, the region decision unit 362 may determine the image data of the second pixel P2 whose respective boundary information has a sixth boundary value as the image data of the 2-3 boundary region BA2-3.

[0160] In addition, the area decision unit 362 may decide image data of an area other than the boundary area BA in the first display area DA1. The area decision unit 362 may decide image data of first pixels P1 whose respective display area information has a value corresponding to the first display area DA1 and whose respective boundary information is 0 as image data of an area other than the boundary area BA in the first display area DA1.

[0161] The area decision unit 362 may decide the image data of the area except the boundary area BA in the second display area DA2. The area decision unit 362 may decide the image data of the second pixels P2 whose respective display area information has a value corresponding to the second display area DA2 and whose respective boundary information is 0 as the image data of the area except the boundary area BA in the second display area DA2.

[0162] The brightness adjustment unit 363 adjusts the brightness of the received image data. Specifically, the brightness adjustment unit 363 may adjust the brightness of each of the area excluding the boundary area BA in the first display area DA1, the boundary area BA, and the area excluding the boundary area BA in the second display area DA2.

[0163] The brightness adjustment unit 363 may perform adjustment so that the brightness of the image data of the boundary area BA has a value between the brightness of the image data of the area other than the boundary area BA in the first display area DA1 and the brightness of the image data of the area other than the boundary area BA in the second display area DA2.

[0164] The brightness adjustment unit 363 may adjust the image data of the area other than the boundary area BA in the first display area DA1 to have a first brightness. The brightness adjustment unit 363 may adjust the image data of the area other than the boundary area BA in the second display area DA2 to have a second brightness different from the first brightness.

[0165] For example, the second brightness may be higher than the first brightness. Since the second display area DA2 includes non-luminescent pixels or non-luminescent sub-pixels, the resolution of the second display area DA2 is lower than the resolution of the first display area DA1. Therefore, the image data applied to the second pixel P2 disposed in the second display area DA2 may have a higher brightness than the image data applied to the first pixel P1 disposed in the first display area DA1.

[0166] In a case where the brightness of the first display area DA1 and the brightness of the second display area DA2 are different from each other, a lining phenomenon and color difference may occur at a boundary B between the first display area DA1 and the second display area DA2 due to the brightness difference between the first display area DA1 and the second display area DA2.

[0167] In the display device 100 according to an embodiment of the present disclosure, the brightness of the boundary area BA located within a predetermined range from the boundary B between the first display area DA1 and the second display area DA2 is adjusted, thereby preventing the lining phenomenon and color difference from occurring at the boundary B between the first display area DA1 and the second display area DA2.

[0168] To this end, the brightness adjustment unit 363 may perform adjustment so that the image data of the boundary area BA has a third brightness which is a value between the first brightness and the second brightness.

[0169] For example, in a case where the second brightness is higher than the first brightness, the third brightness may be higher than the first brightness and may be lower than the second brightness.

[0170] The brightness adjustment unit 363 can adjust the brightness of the image data of each of the first boundary area BA1 and the second boundary area BA2. Specifically, the brightness adjustment unit 363 can perform adjustment so that the brightness of the image data of the first pixel P1 set in the first boundary area BA1 and the brightness of the image data of the second pixel P2 set in the second boundary area BA2 are different from each other.

[0171] For example, in the case where the second brightness is higher than the first brightness, the brightness adjustment unit 363 may perform adjustment so that the brightness of the image data of the first pixel P1 disposed in the first boundary area BA1 is lower than the brightness of the image data of the second pixel P2 disposed in the second boundary area BA2. Therefore, the brightness of the image displayed on the display panel 110 may be gradually reduced in the direction from the second display area DA2 to the first display area DA1. In the display device 100 according to the embodiment of the present disclosure, the brightness does not change suddenly, but gradually changes from the second display area DA2 to the first display area DA1, thereby being able to prevent the lining phenomenon and color difference from occurring.

[0172] In addition, in the case where a plurality of first boundary areas BA1 are provided, the brightness adjustment unit 363 may adjust the brightness of the image data of each of the plurality of first boundary areas BA1-1, BA1-2, and BA1-3. Fig.14 and Fig.15 As shown in FIG. 1 , the brightness adjustment unit 363 may perform adjustment so that the brightness of the image data of each of the plurality of first boundary areas BA1 - 1 , BA1 - 2 , and BA1 - 3 gradually increases or decreases as the distance from the second display area DA2 decreases.

[0173] For example, when the second brightness is higher than the first brightness, the brightness adjustment unit 363 may perform adjustment so that the brightness of the image data of each of the plurality of first boundary areas BA1-1, BA1-2, and BA1-3 gradually increases as the distance from the second display area DA2 decreases.

[0174] In addition, in the case where a plurality of second boundary areas BA2 are provided, the brightness adjustment unit 363 may adjust the brightness of the image data of each of the plurality of second boundary areas BA2-1, BA2-2, and BA2-3. Fig.14 and Fig.15 As shown in , the brightness adjustment unit 363 may perform adjustment so that the brightness of the image data of each of the plurality of second boundary areas BA2-1, BA2-2, and BA2-3 gradually increases or decreases as the distance from the first display area DA1 decreases.

[0175] For example, when the second brightness is higher than the first brightness, the brightness adjustment unit 363 may perform adjustment so that the brightness of the image data of each of the plurality of second boundary areas BA2-1, BA2-2, and BA2-3 gradually decreases as the distance from the first display area DA1 decreases.

[0176] In the display device 100 according to the embodiment of the present disclosure, adjustment is performed so that the brightness of each of the plurality of boundary areas BA is gradually reduced or increased, thereby minimizing the brightness difference between the areas. Therefore, the display device 100 according to the embodiment of the present disclosure can prevent the lining phenomenon occurring between the first display area DA1 and the second display area DA2 having different resolutions from being recognized by the user. In addition, the display device 100 according to the embodiment of the present disclosure can prevent the color difference from occurring between the first display area DA1 and the second display area DA2 having different resolutions.

[0177] The brightness adjustment unit 363 may independently adjust the brightness of each of the plurality of first boundary areas BA1 and the plurality of second boundary areas BA2 .

[0178] In addition, the brightness adjustment unit 363 may perform adjustment so that the brightness changes according to the direction in which the boundary area BA is set based on the central area of ​​the second display area DA2. For example, the boundary area BA may include a left boundary area A1 set in the left direction D1 based on the central area of ​​the second display area DA2, a right boundary area A2 set in the right direction D2 based on the central area of ​​the second display area DA2, an upper boundary area A3 set in the upward direction D3 based on the central area of ​​the second display area DA2, and a lower boundary area A4 set in the downward direction D4 based on the central area of ​​the second display area DA2.

[0179] like Fig.15 As shown in the figure, the boundary area BA may also include an upper left boundary area A5 set in the upper left direction D5 based on the center area of ​​the second display area DA2, an upper right boundary area A6 set in the upper right direction D6 based on the center area of ​​the second display area DA2, a lower right boundary area A7 set in the lower right direction D7 based on the center area of ​​the second display area DA2, and a lower left boundary area A8 set in the lower left direction D8 based on the center area of ​​the second display area DA2.

[0180] Hereinafter, for convenience of description, the boundary area BA will be described as including a left boundary area A1, a right boundary area A2, an upper boundary area A3, and a lower boundary area A4. However, the present disclosure is not limited thereto.

[0181] The brightness adjustment unit 363 may independently adjust the brightness of the image data of the pixels P disposed in each of the left boundary area A1 , the right boundary area A2 , the upper boundary area A3 , and the lower boundary area A4 .

[0182] Specifically, the brightness adjustment unit 363 can perform adjustment so that the brightness value of the image data of each of the left boundary area A1, the right boundary area A2, the upper boundary area A3 and the lower boundary area A4 is between the first brightness of the image data of the area other than the boundary area BA in the first display area DA1 and the second brightness of the image data of the area other than the boundary area BA in the second display area DA2.

[0183] The brightness adjustment unit 363 may perform adjustment so that the image data of the left border area A1 has a fourth brightness, which is a value between the first brightness and the second brightness. The brightness adjustment unit 363 may perform adjustment so that the image data of the right border area A2 has a fifth brightness, which is a value between the first brightness and the second brightness. The brightness adjustment unit 363 may perform adjustment so that the image data of the upper border area A3 has a sixth brightness, which is a value between the first brightness and the second brightness. The brightness adjustment unit 363 may perform adjustment so that the image data of the lower border area A4 has a seventh brightness, which is a value between the first brightness and the second brightness.

[0184] Although each of the fourth brightness, the fifth brightness, the sixth brightness, and the seventh brightness has a value between the first brightness and the second brightness, they may all have different values, or some may have the same value and some may have different values. That is, the brightness adjustment unit 363 may independently adjust the brightness of the image data of each of the left boundary area A1, the right boundary area A2, the upper boundary area A3, and the lower boundary area A4.

[0185] More specifically, the brightness change value of each of the left boundary area A1, the right boundary area A2, the upper boundary area A3, and the lower boundary area A4 may be preset. A first brightness change value may be set for the left boundary area A1, a second brightness change value may be set for the right boundary area A2, a third brightness change value may be set for the upper boundary area A3, and a fourth brightness change value may be set for the lower boundary area A4.

[0186] At this time, the first brightness change value, the second brightness change value, the third brightness change value, and the fourth brightness change value may be determined in consideration of the pitch between the pixels P. The first brightness change value may be determined based on the pitch between one pixel P and the adjacent pixel P set in the left direction D1. The second brightness change value may be determined based on the pitch between one pixel P and the adjacent pixel P set in the right direction D2. The third brightness change value may be determined based on the pitch between one pixel P and the adjacent pixel P set in the upward direction D3. The fourth brightness change value may be determined based on the pitch between one pixel P and the adjacent pixel P set in the downward direction D4.

[0187] For example, the brightness change value may be proportional to the pitch between the pixels P. In the case where the pitch between the pixels P is large, the brightness change value may increase. On the other hand, in the case where the pitch between the pixels P is small, the brightness change value may decrease.

[0188] The brightness adjustment unit 363 may adjust the brightness of the image data of the pixels P disposed in the relevant boundary area BA by reflecting the brightness change value set for the relevant boundary area BA in the image data of the pixels P disposed in the relevant boundary area BA.

[0189] In addition, if Fig.14 and Fig.15 As shown in , each of the left border region A1, the right border region A2, the upper border region A3, and the lower border region A4 may be divided into a plurality of border regions. For example, each of the left border region A1, the right border region A2, the upper border region A3, and the lower border region A4 may include a first border region BA1 disposed adjacent to the border B in the first display region DA1 and a second border region BA2 disposed adjacent to the border B in the second display region DA2. At this time, a plurality of first border regions BA1 may be disposed, and a plurality of second border regions BA2 may also be disposed.

[0190] The brightness adjustment unit 363 may independently adjust the brightness of each of the plurality of first boundary areas BA1 and the plurality of second boundary areas BA2 as previously described. In this case, the brightness change value may include a plurality of values ​​for the plurality of first boundary areas BA1 and the plurality of second boundary areas BA2.

[0191] For example, each of the left boundary area A1, the right boundary area A2, the upper boundary area A3, and the lower boundary area A4 may include three first boundary areas BA1 and three second boundary areas BA2. At this time, the first brightness change value of the left boundary area A1 may include values ​​for the three first boundary areas BA1 and the three second boundary areas BA2, that is, six brightness change values. As a result, the brightness adjustment unit 363 may set 24 brightness change values ​​for the 24 boundary areas. The brightness adjustment unit 363 may use the set brightness change values ​​to adjust the brightness of the image data of each of the 24 boundary areas.

[0192] The control unit 370 performs control so that the corrected image is displayed on the display panel 110. To this end, the control unit 370 may generate a control signal for controlling the panel driving unit 130. The control unit 370 may generate a data control signal for a data driving unit of the panel driving unit 130 and a gate control signal for a gate driving unit of the panel driving unit 130. The control unit 370 may output the data control signal, the gate control signal, and the image data signal to the panel driving unit 130.

[0193] The control unit 370 may control the operation of the optical module 120. To this end, the control unit 370 may generate a control signal for controlling the optical driving unit 140, and may output the generated control signal to the optical driving unit 140.

[0194] As is apparent from the above description, it is possible to display an image even in an area arranged to overlap with a camera. Therefore, in the present disclosure, it is possible to provide a wide image display surface and prevent the image from being interrupted in an area where a camera is located.

[0195] In addition, according to the present disclosure, the shape information of the area set to overlap with the camera can be stored and the display area information and boundary information of each of the plurality of pixels can be acquired using the shape information. Therefore, in the present disclosure, even if the size, position, etc. of the camera are changed, it is sufficient to change only the shape information of the area set to overlap with the camera stored in the memory, thereby making it possible to easily change the shape of the area set to overlap with the camera.

[0196] In addition, according to the present disclosure, the boundary of the area set to overlap with the camera can be easily obtained based only on the position information and vertical length information of the starting point, the direction information of the line, and the width information of the area set to overlap with the camera. Therefore, in the present disclosure, the amount of information stored in the memory can be minimized, thereby enabling the use of a small-capacity memory.

[0197] In addition, according to the present disclosure, the boundary of the area set to overlap with the camera can be acquired by simple calculation, whereby the amount of calculation is low in the process of independently controlling the general display area and the display area set to overlap with the camera.

[0198] In addition, according to the present disclosure, adjustment is performed so that the brightness of each of the plurality of boundary regions is gradually reduced or increased, thereby minimizing the brightness difference between the regions. Therefore, in the present disclosure, the lining phenomenon occurring between display regions with different resolutions can be prevented from being recognized by the user.

[0199] In addition, according to the present disclosure, it is possible to prevent color difference from occurring between display areas having different resolutions.

[0200] It should be noted that the effects of the present disclosure are not limited to the above-mentioned effects, and other unmentioned effects will be clearly understood by those skilled in the art from the above description of the present disclosure.

[0201] Those skilled in the art will appreciate that the present disclosure may be embodied in specific forms other than those set forth herein without departing from the technical concept and essential characteristics of the present disclosure.

[0202] For example, the data driving device according to the present disclosure may be implemented in the form of an IC, and the function of the data driving device may be installed in the IC in the form of a program. In the case where the function of the data driving device according to the present disclosure is implemented as a program, the function of each component included in the data driving device may be implemented as a specific code, and the code for implementing the specific function may be implemented as a single program or a plurality of separate programs.

[0203] Therefore, the above embodiments are therefore to be understood as illustrative in all aspects and not restrictive. The scope of the present disclosure is defined by the appended claims rather than the specific description, and it is intended that all variations or modifications derived from the meaning, scope and equivalent concepts of the claims fall within the scope of the present disclosure.
