Abstract
Description
Technical Field
[0001] The present invention relates to a display device and an electronic device including the same, and more particularly, to a display device including a wiring hybrid structure to improve demultiplexing coupling and prevent data mapping errors, and an electronic device including the same. Background Art
[0002] Generally, a display device includes a display panel and a display panel driving unit. The display panel displays an image based on an input image, and includes a plurality of gate lines, a plurality of data lines, and a plurality of pixels. The display panel driving unit includes: a gate driving unit that provides a gate signal to the plurality of gate lines; a data driving unit that provides a data voltage to the data lines; and a driving control unit that controls the gate driving unit and the data driving unit.
[0003] The display panel driving unit may include a demultiplexer circuit that separates R-G data of the data driving unit into R data and G data, and separates B-G data of the data driving unit into B data and G data. In a display device including the demultiplexer circuit, the display quality may be degraded due to coupling between a data line that outputs R data or B data and a data line that outputs G data.
[0004] Moreover, in order to reduce the dead space of the display device, the data driving unit may be formed into a border reduction structure (BRS) capable of cross-outputting a data voltage applied to a data line at the center of the display panel and a data voltage applied to a data line at the edge of the display panel. In this case, a horizontal wiring for transmitting the data voltage to the edge data line may be additionally provided, and the display quality may be degraded due to the coupling between such horizontal wiring and the data line.
[0005] Furthermore, in order to reduce the dead space of the display device, the position of the demultiplexer circuit is moved toward the integrated circuit side of the data driving unit. In this case, the number of floating lines on the display panel further increases, resulting in more coupling and further degrading the display quality.
[0006] Moreover, in the case where the output of the data driving unit of the prior art is directly connected to the data line of the display panel due to the movement of the demultiplexer circuit, data mapping errors may occur in which R data or B data is applied to a G pixel, or G data is applied to an R pixel or a B pixel.

[0048] 100: Display panel; 200: Drive control unit; 300: Gate drive unit; 400: Gamma reference voltage generation unit; 500: Data drive unit Detailed Description of the Invention
[0049] Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.
[0050] Figure 1 is a block diagram of a display device showing an embodiment of the present invention.
[0051] Referring to Figure 1 , the display device includes a display panel 100 and a display panel drive unit. The display panel drive unit includes: a drive control unit 200, a gate drive unit 300, a gamma reference voltage generation unit 400, and a data drive unit 500.
[0052] For example, the drive control unit 200 and the data drive unit 500 may be integrally formed. For example, the drive control unit 200, the gamma reference voltage generation unit 400, and the data drive unit 500 may be integrally formed. A drive module obtained by integrally forming at least the drive control unit 200 and the data drive unit 500 may be referred to as a timing controller embedded data driver (TED).
[0053] The display panel 100 includes: a display unit AA for displaying an image; and a peripheral unit PA disposed adjacent to the display unit AA.
[0054] The display panel 100 includes: a plurality of gate lines GL, a plurality of data lines DL, and a plurality of pixels P electrically connected to the gate lines GL and the data lines DL, respectively. The gate lines GL may extend in a first direction D1, and the data lines DL extend in a second direction D2 intersecting the first direction D1.
[0055] The driving control unit 200 receives input image data IMG and an input control signal CONT from an external device. For example, the input image data IMG may include red image data, green image data, and blue image data. The input image data IMG may include white image data. The input image data IMG may include magenta image data, yellow image data, and cyan image data. The input control signal CONT may include a main clock signal and a data enable signal. The input control signal CONT may further include a vertical synchronization signal and a horizontal synchronization signal.
[0056] The driving control unit 200 generates a first control signal CONT1, a second control signal CONT2, a third control signal CONT3, and a data signal DATA based on the input image data IMG and the input control signal CONT.
[0057] The driving control unit 200 generates the first control signal CONT1 for controlling the operation of the gate driving unit 300 based on the input control signal CONT and outputs it to the gate driving unit 300. The first control signal CONT1 may include a vertical start signal and a gate clock signal.
[0058] The driving control unit 200 generates the second control signal CONT2 for controlling the operation of the data driving unit 500 based on the input control signal CONT and outputs it to the data driving unit 500. The second control signal CONT2 may include a horizontal start signal and a load signal.
[0059] The driving control unit 200 generates a data signal DATA based on the input image data IMG. The driving control unit 200 outputs the data signal DATA to the data driving unit 500.
[0060] The driving control unit 200 generates the third control signal CONT3 for controlling the operation of the gamma reference voltage generation unit 400 based on the input control signal CONT and outputs it to the gamma reference voltage generation unit 400.
[0061] The gate driving unit 300 generates a gate signal for driving the gate line GL in response to the first control signal CONT1 received from the driving control unit 200. The gate driving unit 300 outputs the gate signal to the gate line GL. For example, the gate driving unit 300 may sequentially output the gate signal to the gate line GL. For example, the gate driving unit 300 may be mounted on the peripheral portion PA of the display panel 100. For example, the gate driving unit 300 may be integrated into the peripheral portion PA of the display panel 100.
[0062] The gamma reference voltage generation unit 400 generates a gamma reference voltage VGREF in response to the third control signal CONT3 received from the driving control unit 200. The gamma reference voltage generation unit 400 provides the gamma reference voltage VGREF to the data driving unit 500. The gamma reference voltage VGREF has a value corresponding to each data signal DATA.
[0063] In an embodiment of the present invention, the gamma reference voltage generation unit 400 may be configured within the driving control unit 200 or within the data driving unit 500.
[0064] The data driving unit 500 receives the second control signal CONT2 and the data signal DATA from the driving control unit 200, and receives the gamma reference voltage VGREF from the gamma reference voltage generation unit 400. The data driving unit 500 transforms the data signal DATA into an analog data voltage by using the gamma reference voltage VGREF. The data driving unit 500 outputs the data voltage to the data line DL.
[0065] Figure 2 is a conceptual diagram showing Figure 1 the display panel 100 and the data driving unit 500.
[0066] Referring to Figure 1 and Figure 2 the display panel 100 may include the display portion AA and the peripheral portion PA. The peripheral portion PA of the display panel 100 may be connected to the bending area BDA. The bending area BDA may include a bending line BL that bends toward the back surface of the display panel 100. The bending area BDA may be configured between the display panel 100 and the data driving unit 500.
[0067] The data driving unit 500 may be formed in the form of a data driving chip DIC. The data driving chip DIC may be configured in the integrated circuit area ICA of the data driving unit 500.
[0068] The display device may further include a demultiplexer circuit DXA. The demultiplexer circuit DXA may be disposed between the integrated circuit area ICA and the bending area BDA.
[0069] The display panel 100 may be disposed on a first side of the bending line BL, and the demultiplexer circuit DXA and the integrated circuit area ICA may be disposed on a second side of the bending line BL. The demultiplexer circuit DXA and the integrated circuit area ICA may be bent toward the back surface of the display panel 100. In this embodiment, since the demultiplexer circuit DXA is bent toward the back surface of the display panel 100, compared with the case where the demultiplexer circuit DXA is disposed in the peripheral area PA of the display panel 100, the invalid space of the display device can be reduced.
[0070] The data driving unit 500 may be formed into a boundary reduction structure capable of cross-outputting data voltages applied to data lines (e.g., DL3, DL4) in the central portion of the display panel 100 and data voltages applied to data lines DL1, DL2 at the edge of the display panel 100. The display panel 100 may further include lateral wirings BRS1, BRS2 for transmitting data voltages to the data lines DL1, DL2 at the edge.
[0071] Figure 3 FIG. is an illustration showing an example where coupling occurs in a demultiplexer switch structure.
[0072] Refer to Figures 1 to 3 , Figure 3 The CLA of may represent a switching signal of a first switch of the demultiplexer circuit DXA, and the CLB represents a switching signal of a second switch of the demultiplexer circuit DXA. In Figure 3 it is illustrated that the CLA outputs data of green pixels and the CLB outputs data of red and blue pixels. Differently, it may also be that the CLA outputs data of red and blue pixels and the CLB outputs data of green pixels.
[0073] According to an embodiment, the timing GW ON of turning on the gate signal may be synchronized with the timing when the CLA remains low level and high level, and may be synchronized with the timing when the CLB changes from high level to low level or from low level to high level. Thus, when the display panel 100 displays a zebra pattern, in the first GW ON timing, the brightness of the green pixels becomes brighter due to coupling (represented by a dotted line), and there may be a problem that the image becomes greenish.
[0074] As described above, when the data output path synchronized with the CLA and the data output path synchronized with the CLB are arranged adjacent to each other, a problem of reduced display quality due to coupling may occur.
[0075] Figure 4 is a table showing Figure 1 the output amplifiers of the data driver unit 500 and data mapping. Figure 5 is a diagram showing Figure 1 the data lines, border reduction horizontal lines, border reduction vertical lines, and power supply connection lines of the display panel 100. Figure 6 is a diagram showing Figure 1 the light-emitting area of the display panel 100.
[0076] Figure 7A is a conceptual diagram showing Figure 1 the output amplifiers, demultiplexer circuit, wiring hybrid structure of the data driver unit 500, and the display panel 100. Figure 7B is a conceptual diagram that magnifies and shows Figure 7A the wiring hybrid structure.
[0077] Referring to Figures 1 to 7B , the display device includes: a data driver unit 500, a demultiplexer circuit DXA, a wiring hybrid structure, and a display panel 100. In this embodiment, a 4-bundle structure in which the demultiplexer switch has a structure of A-A-B-B-B-B-A-A is shown. In Figures 4 to 7B , a case where the CLA corresponds to the data of the red and blue pixels and the CLB corresponds to the data of the green pixels is illustrated. As shown in the PDB region of Figure 7A , the demultiplexer switch structure can be repeated in units of "A-A-B-B-B-B-A-A" (for example, 200A-201A-201B-200B-199B-202B-202A-199A). If a case where the demultiplexer switch structure is repeated more than twice in units of "A-A-B-B-B-B-A-A" is illustrated, the demultiplexer switch structure may be "A-A-B-B-B-B-A-A-A-A-B-B-B-B-A-A…". In this case, if the initial starting part and the terminating part are removed, the data corresponding to the CLA (R data or B data) will be continuously arranged four by four, and the data corresponding to the CLB (G data) will be continuously arranged four by four. Therefore, the possibility of reduced image quality due to coupling between the data corresponding to the CLA and the data corresponding to the CLB is relatively reduced.
[0078] For example, the data driver unit 500 includes first to fourth output amplifiers Y1, Y2, Y3, and Y4.
[0079] The demultiplexer circuit DXA can divide the first to fourth output amplifiers Y1, Y2, Y3, and Y4 into first to eighth output lines through a demultiplexer switch.
[0080] For example, the first, fourth, fifth, and eighth output lines of the demultiplexer circuit DXA can be activated by a first switch signal CLA, and the second, third, sixth, and seventh output lines of the demultiplexer circuit are activated by a second switch signal CLB.
[0081] When configured as described above, Figure 7A data corresponding to CLA will be continuously configured two by two and data corresponding to CLB will be continuously configured two by two (e.g., 201A - 201B - 200B - 200A - 202A - 202B - 199B - 199A). When the order of the third data at the input end of the demultiplexer circuit DXA is 1, 2, 3, 4, 5, 6, 7, 8, the order of the fourth data at the output end of the demultiplexer circuit DXA can be 1, 2, 4, 3, 5, 6, 8, 7.
[0082] The wiring hybrid structure is connected to the demultiplexer circuit DXA. The display panel 100 includes data lines connected to the wiring hybrid structure.
[0083] In this embodiment, when the order of the first data at the input end PDA of the wiring hybrid structure is 1, 2, 3, 4, 5, 6, 7, 8, the order of the second data at the output end PDB of the wiring hybrid structure is 4, 1, 2, 3, 7, 6, 5, 8.
[0084] Referring to Figure 4 , the first output amplifier Y1 can be an amplifier that alternately outputs B data and G data. The second output amplifier Y2 can be an amplifier that alternately outputs R data and G data.
[0085] In Figure 5 , the display panel 100 can include: a dummy area DA, a boundary reduction area BA, a normal - boundary reduction area NBA, and a normal area NA. A dummy data line DM can be configured in the dummy area DA. In this embodiment, although the case where one dummy data line DM is configured in the dummy area DA is illustrated, the present invention is not limited thereto.
[0086] In the boundary reduction area BA, the 1A data line to the 200A data line and the 1B data line to the 200B data line can be configured. In this embodiment, although the case where 400 data lines are configured in the boundary reduction area BA is illustrated, the present invention is not limited thereto.
[0087] The 1st A data line to the 200th A data line and the 1st B data line to the 200th B data line within the boundary reduction region BA can receive data through the boundary reduction horizontal line BRSA and the boundary reduction vertical line BRSB.
[0088] Two power supply access lines EOA can be arranged between two adjacent data lines within the boundary reduction region BA. Also, between two other adjacent data lines within the boundary reduction region BA, the power supply access line EOA may not be arranged. For example, the power supply access line EOA may not be arranged between the 1st A data line and the 1st B data line. On the other hand, two power supply access lines EOA can be arranged between the 1st B data line and the 2nd B data line. The power supply access line EOA can be a wiring for applying a low power supply voltage to the pixel.
[0089] The 201st A data line to the 400th A data line and the 201st B data line to the 400th B data line can be arranged in the normal-boundary reduction region NBA. In this embodiment, although the case where 400 data lines are arranged in the normal-boundary reduction region NBA is illustrated, the present invention is not limited thereto. The data lines within the normal-boundary reduction region NBA can receive data directly from the data driving unit 500 without passing through the boundary reduction horizontal line BRSA and the boundary reduction vertical line BRSB. The boundary reduction horizontal line BRSA is arranged within the normal-boundary reduction region NBA, so that data can be transmitted to the boundary reduction region BA through the boundary reduction vertical line BRSB.
[0090] In the normal-boundary reduction region NBA, a part of the power supply access line EOA can be used as the boundary reduction horizontal line BRSA. When a part of the power supply access line EOA is used as the boundary reduction horizontal line BRSA, the part of the power supply access line EOA used as the boundary reduction horizontal line BRSA and the part of the power supply access line EOA not used as the boundary reduction horizontal line BRSA can be insulated from each other. The part of the power supply access line EOA used as the boundary reduction horizontal line BRSA cannot function to apply a low power supply voltage to the pixel, and the part of the power supply access line EOA not used as the boundary reduction horizontal line BRSA can function to apply a low power supply voltage to the pixel.
[0091] In the normal region NA, the 401A data line to the 540A data line and the 401B data line to the 540B data line can be configured. In this embodiment, although a case where 280 data lines are configured in the normal region NA is illustrated, the present invention is not limited thereto. The data lines in the normal region NA can directly receive data from the data driving unit 500 without passing through the boundary reduction horizontal line BRSA and the boundary reduction vertical line BRSB. And, the boundary reduction horizontal line BRSA may not be configured in the normal region NA. That is, in the normal region NA, the power supply access line EOA can only be used to apply the low power supply voltage.
[0092] Figure 5 The display panel 100 shown in [reference] can correspond to half of the entire display area, and the display panel 100 can be line-symmetric with respect to the center line CL.
[0093] Refer to Figure 5 , the display panel 100 can include a first power supply access line, a 1A data line 1A, a 1B data line 1B, a second power supply access line, a third power supply access line, a 2B data line 2B, a 2A data line 2A, and a fourth power supply access line, which are arranged in sequence.
[0094] First color data can be applied to the 1A data line 1A, second color data can be applied to the 1B data line 1B and the 2B data line 2B, and third color data can be applied to the 2A data line 2A. For example, the first color data can be blue data, the second color data is green data, and the third color data is red data.
[0095] As Figure 6 shown, the display panel 100 can include: a first color first light-emitting region B11, a second color first light-emitting region G11, a third color first light-emitting region R11, a second color second light-emitting region G12, a third color second light-emitting region R21, a second color third light-emitting region G21, a first color second light-emitting region B21, and a second color fourth light-emitting region G22.
[0096] Refer to together Figure 6 and Figure 7A , Figure 7A The 1A data line 1A of [reference] can be a line for applying first color data (for example, blue data), which is connected to Figure 6 the first color first light-emitting region B11 of [reference] and Figure 6 the first color second light-emitting region B21 of [reference]. Figure 7A The 1B data line 1B of [reference] can be a line for applying second color data (for example, green data), which is connected to Figure 6 the second color first light-emitting region G11 of [reference] andFigure 6 is connected to the second-color third light-emitting region G21. Figure 7A The 2B data line 2B can be a line for applying second-color data (e.g., green data), which is connected to Figure 6 the second-color second light-emitting region G12 and Figure 6 the second-color fourth light-emitting region G22. Figure 7A The 2A data line 2A can be a line for applying third-color data (e.g., red data), which is connected to Figure 6 the third-color first light-emitting region R11 and Figure 6 the third-color third light-emitting region R22.
[0097] Although not shown, Figure 6 the first-color third light-emitting region B12 can be arranged adjacent to Figure 7A the 2A data line 2A, and is connected to the 3A data line for applying first-color data (e.g., blue data).
[0098] And, Figure 6 the third-color second light-emitting region R21 can be connected to Figure 7A the dummy data line DM.
[0099] For example, the second-color first light-emitting region G11 and the second-color second light-emitting region G12 can be arranged in the 1-1 row, the first-color first light-emitting region B11 and the third-color first light-emitting region R11 are arranged in the 1-2 row adjacent to the 1-1 row, the second-color third light-emitting region G21 and the second-color fourth light-emitting region G22 are arranged in the 2-1 row adjacent to the 1-2 row, and the third-color second light-emitting region R21 and the first-color second light-emitting region B21 are arranged in the 2-2 row adjacent to the 2-1 row.
[0100] Among them, four pixels of G11, B11, G21, and R11 can be arranged in a diamond shape. Similarly, four pixels of G12, R11, G22, and B12 can also be arranged in a diamond shape. Similarly, four pixels of R11, G21, B21, and G22 can also be arranged in a diamond shape.
[0101] A part of the output data of the data driving unit 500 can be normal data NORMAL directly applied to the data line DL of the display panel 100, and a part of the output data of the data driving unit 500 is boundary reduction data BRS applied to the data line DL of the display panel 100 through the boundary reduction vertical line BRSB.
[0102] For example, when the order of the first data of the input end PDA of the wiring hybrid structure is 1, 2, 3, 4, 5, 6, 7, 8, the first data with the order of 1, 2, 5, 6 (e.g., Figure 7A 201A, 201B, 202A, 202B) can be the normal data NORMAL, and the first data with the order of 3, 4, 7, 8 (e.g., Figure 7A 200B, 200A, 199B, 199A) is the boundary reduction data BRS.
[0103] In this embodiment, the data corresponding to the 1st to 200th data lines can be the boundary reduction data BRS. On the other hand, the data corresponding to the 201st to 540th data lines is the normal data NORMAL.
[0104] As Figure 7B shown, the input end PDA of the wiring hybrid structure may include the 1st to 8th A pads A1 to A8 arranged in sequence, and the output end PDB of the wiring hybrid structure includes the 1st to 8th B pads B1 to B8 arranged in sequence.
[0105] Among them, the 1st A pad A1 can be connected to the 2nd B pad B2, the 2nd A pad A2 is connected to the 3rd B pad B3, the 3rd A pad A3 is connected to the 4th B pad B4, the 4th A pad A4 is connected to the 1st B pad B1, the 5th A pad A5 is connected to the 7th B pad B7, the 6th A pad A6 is connected to the 6th B pad B6, the 7th A pad A7 is connected to the 5th B pad B5, and the 8th A pad A8 is connected to the 8th B pad B8. Through the wiring hybrid structure as described above, when the order of the first data of the input end PDA of the wiring hybrid structure is 1, 2, 3, 4, 5, 6, 7, 8, the order of the second data of the output end PDB of the wiring hybrid structure can be 4, 1, 2, 3, 7, 6, 5, 8.
[0106] Previously, the data corresponding to CLA was continuously configured in two and the data corresponding to CLB was continuously configured in two (201A - 201B - 200B - 200A - 202A - 202B - 199B - 199A). However, through the wiring hybrid structure, from Figure 7A it can be changed to the data corresponding to CLA being continuously configured in four and the data corresponding to CLB being continuously configured in four (200A - 201A - 201B - 200B - 199B - 202B - 202A - 199A). That is, the 4 - bundle structure can be implemented by using the wiring hybrid structure, and the data mapping error in the 4 - bundle structure can be prevented by using the wiring hybrid structure.
[0107] Figure 8 It is a conceptual diagram of an output amplifier, a demultiplexer circuit, and a display panel 100 of a data driver unit 500 that outputs dummy data to a dummy data line DM of the display panel 100 for Figure 1 .
[0108] Referring to Figures 1 to 8 , the data driver unit 500 may further include: an (N + 1)th output amplifier (for example, Y401), an (N + 2)th output amplifier (for example, Y402), an (N + 3)th output amplifier (for example, Y403), an (N + 4)th output amplifier (for example, Y404), an (N + 5)th output amplifier (for example, Y405), an (N + 6)th output amplifier (for example, Y406), an (N + 7)th output amplifier (for example, Y407), and an (N + 8)th output amplifier (for example, Y408). Among them, the (N + 1)th output amplifier (for example, Y401) may be an output amplifier that outputs blue data and green data, the (N + 2)th output amplifier (for example, Y402) is an output amplifier that outputs red data and green data, the (N + 3)th output amplifier (for example, Y403) is an output amplifier that outputs red data and green data, the (N + 4)th output amplifier (for example, Y404) is an output amplifier that outputs blue data and green data, the (N + 5)th output amplifier (for example, Y405) is an output amplifier that outputs blue data and green data, the (N + 6)th output amplifier (for example, Y406) is an output amplifier that outputs red data and green data, the (N + 7)th output amplifier (for example, Y407) is an output amplifier that outputs red data and green data, and the (N + 8)th output amplifier (for example, Y408) is an output amplifier that outputs blue data and green data.
[0109] For example, in the normal area NA, a 401A data line to a 540A data line and a 401B data line to a 540B data line may be arranged.
[0110] For example, the (N + 1)th output amplifier (for example, Y401) may output data for the (N + 1)A data line (for example, the 401A data line) and the (N + 1)B data line (for example, the 401B data line), and the (N + 2)th output amplifier (for example, Y402) may output data for the dummy data line DM.
[0111] That is, the (N + 1)th output amplifier (for example, Y401) may be used for outputting normal data to the normal area NA, and the (N + 2)th output amplifier (for example, Y402) is used for outputting data of the dummy data line DM.
[0112] Moreover, the (N + 3)th output amplifier (e.g., Y403), the (N + 4)th output amplifier (e.g., Y404), and the (N + 5)th output amplifier (e.g., Y405) may not be activated. In this embodiment, the dummy data line DM is connected to the red pixels and corresponds to the boundary reduction data BRS. Therefore, in order to output the boundary reduction data BRS of the red color to the dummy data line DM, an output amplifier group with four units can be used (including a first amplifier for outputting blue normal data and green normal data, a second amplifier for outputting red boundary reduction data and green boundary reduction data, a third amplifier for outputting red normal data and green normal data, and a fourth amplifier for outputting blue boundary reduction data and green boundary reduction data). Thus, in order to output the red boundary reduction data to the dummy data line DM connected to the red pixels, the (N + 2)th output amplifier (e.g., Y402) is activated. On the other hand, the (N + 3)th output amplifier (e.g., Y403), the (N + 4)th output amplifier (e.g., Y404), and the (N + 5)th output amplifier (e.g., Y405) may not be activated.
[0113] The dummy data can be applied to the dummy data line DM via a boundary reduction vertical line configured between the 400A data line and the 401A data line and a boundary reduction horizontal line connected thereto.
[0114] Moreover, the (N + 6)th output amplifier (e.g., Y406) can output the data of the (N + 2)A data line (e.g., the 402A data line) and the (N + 2)B data line (e.g., the 402B data line), the (N + 7)th output amplifier (e.g., Y407) outputs the data of the (N + 3)A data line (e.g., the 403A data line) and the (N + 3)B data line (e.g., the 403B data line), and the (N + 8)th output amplifier (e.g., Y408) outputs the data of the (N + 4)A data line (e.g., the 404A data line) and the (N + 4)B data line (e.g., the 404B data line). The (N + 6)th output amplifier (e.g., Y406), the (N + 7)th output amplifier (e.g., Y407), and the (N + 8)th output amplifier (e.g., Y408) can all output normal data.
[0115] According to this embodiment, since it includes a demultiplexer switch structure supporting 4-wire bundles and a wiring mixing structure for preventing data mapping errors, the demultiplexing coupling can be improved and data mapping errors can be prevented.
[0116] Moreover, in the case of an integrated circuit without a data driving unit 500 and a change in the active area of the display panel 100, a demultiplexer switch structure supporting 4-wire bundles can be supported.
[0117] Moreover, since the data driving unit 500 is configured to have a boundary reduction structure that can cross-output the data voltages applied to the data lines in the central portion of the display panel 100 and the data voltages applied to the data lines at the edges of the display panel, the invalid space of the display device can be reduced.
[0118] Moreover, since the demultiplexer circuit is disposed adjacent to the integrated circuit region on the second side of the curved line, the invalid space of the display device can be further reduced.
[0119] Moreover, by including the configuration of the data driving unit 500 for applying dummy data to the dummy data line DM, appropriate data can be applied to the dummy data line.
[0120] Figure 9 FIG. is a conceptual diagram showing an output amplifier, a demultiplexer circuit, and the display panel 100 of the data driving unit 500 for outputting dummy data to the dummy data line DM of the display panel 100 of a display device according to an embodiment of the present invention.
[0121] The display device according to the present embodiment is substantially the same as the display device Figures 1 to 8 except for the output amplifier, the demultiplexer circuit, and the structure of the display panel of the data driving unit for outputting dummy data. Therefore, the same reference numerals will be used for the same or similar parts, and redundant descriptions will be omitted.
[0122] Refer to Figures 1 to 7B and Figure 9 , the display device includes: a data driving unit 500, a demultiplexer circuit DXA, a wiring hybrid structure, and a display panel 100. In the present embodiment, a 4-bundle structure in which the demultiplexer switch has a structure of A-A-B-B-B-B-A-A is shown. Figures 4 to 7B illustrates a case where CLA corresponds to the data of red and blue pixels, and CLB corresponds to the data of green pixels. As Figure 7AAs shown in the PDB region, the demultiplexer switch structure can be repeated in units of "A-A-B-B-B-B-A-A" (e.g., 200A-201A-201B-200B-199B-202B-202A-199A). If the illustrated demultiplexer switch structure is repeated more than twice in units of "A-A-B-B-B-B-A-A", then the demultiplexer switch structure can be "A-A-B-B-B-B-A-A-A-A-B-B-B-B-A-A…". In this case, if the initial starting part and the terminating part are removed, four data corresponding to CLA (R data or B data) are continuously configured, and four data corresponding to CLB (G data) are continuously configured. Therefore, the possibility of image quality degradation caused by coupling between the data corresponding to CLA and the data corresponding to CLB is relatively reduced.
[0123] For example, the data driver unit 500 includes first to fourth output amplifiers Y1, Y2, Y3, and Y4.
[0124] The demultiplexer circuit DXA can distribute the first to fourth output amplifiers Y1, Y2, Y3, and Y4 to first to eighth output lines through a demultiplexer switch.
[0125] For example, the first, fourth, fifth, and eighth output lines of the demultiplexer circuit DXA are activated by a first switch signal CLA, and the second, third, sixth, and seventh output lines of the demultiplexer circuit are activated by a second switch signal CLB.
[0126] When configured as described above, Figure 7A two data corresponding to CLA and two data corresponding to CLB are continuously configured (e.g., 201A-201B-200B-200A-202A-202B-199B-199A). When the order of the third data at the input end of the demultiplexer circuit DXA is 1, 2, 3, 4, 5, 6, 7, 8, the order of the fourth data at the output end of the demultiplexer circuit DXA can be 1, 2, 4, 3, 5, 6, 8, 7.
[0127] The wiring hybrid structure is connected to the demultiplexer circuit DXA. The display panel 100 includes data lines connected to the wiring hybrid structure.
[0128] In this embodiment, when the order of the first data at the input end PDA of the wiring hybrid structure is 1, 2, 3, 4, 5, 6, 7, 8, the order of the second data at the output end PDB of the wiring hybrid structure is 4, 1, 2, 3, 7, 6, 5, 8.
[0129] The data driving unit 500 may further include: an (N + 1)th output amplifier (e.g., Y401), an (N + 2)th output amplifier (e.g., Y402), an (N + 3)th output amplifier (e.g., Y403), an (N + 4)th output amplifier (e.g., Y404), an (N + 5)th output amplifier (e.g., Y405), an (N + 6)th output amplifier (e.g., Y406), an (N + 7)th output amplifier (e.g., Y407), and an (N + 8)th output amplifier (e.g., Y408). Among them, the (N + 1)th output amplifier (e.g., Y401) may be an output amplifier that outputs blue data and green data, the (N + 2)th output amplifier (e.g., Y402) is an output amplifier that outputs red data and green data, the (N + 3)th output amplifier (e.g., Y403) is an output amplifier that outputs red data and green data, the (N + 4)th output amplifier (e.g., Y404) is an output amplifier that outputs blue data and green data, the (N + 5)th output amplifier (e.g., Y405) is an output amplifier that outputs blue data and green data, the (N + 6)th output amplifier (e.g., Y406) is an output amplifier that outputs red data and green data, the (N + 7)th output amplifier (e.g., Y407) is an output amplifier that outputs red data and green data, and the (N + 8)th output amplifier (e.g., Y408) is an output amplifier that outputs blue data and green data.
[0130] For example, in the normal region NA, a 401A data line to a 540A data line and a 401B to a 540B data line may be configured.
[0131] For example, the (N + 5)th output amplifier (e.g., Y405) may output data for the (N + 1)A data line (e.g., the 401A data line) and the (N + 1)B data line (e.g., the 401B data line), and the (N + 2)th output amplifier (e.g., Y402) may output data for the dummy data line DM.
[0132] That is, the (N + 5)th output amplifier (e.g., Y405) may be used for outputting normal data to the normal region NA, and the (N + 2)th output amplifier (e.g., Y402) is used for outputting data of the dummy data line DM.
[0133] Moreover, the (N + 1)th output amplifier (e.g., Y401), the (N + 3)th output amplifier (e.g., Y403), and the (N + 4)th output amplifier (e.g., Y404) may not be activated. In this embodiment, the dummy data line DM is connected to the red pixels and corresponds to the boundary reduction data BRS. Therefore, in order to output the boundary reduction data BRS of the red color to the dummy data line DM, an output amplifier group with four units can be used (including a first amplifier for outputting blue normal data and green normal data, a second amplifier for outputting red boundary reduction data and green boundary reduction data, a third amplifier for outputting red normal data and green normal data, and a fourth amplifier for outputting blue boundary reduction data and green boundary reduction data). Thus, in order to output the red boundary reduction data to the dummy data line DM connected to the red pixels, the (N + 2)th output amplifier (e.g., Y402) is activated, while on the other hand, the (N + 1)th output amplifier (e.g., Y401), the (N + 3)th output amplifier (e.g., Y403), and the (N + 4)th output amplifier (e.g., Y404) may not be activated.
[0134] The dummy data can be applied to the dummy data line DM via a boundary reduction vertical line configured between the 400A data line and the 401A data line and a boundary reduction horizontal line connected thereto.
[0135] Moreover, the (N + 6)th output amplifier (e.g., Y406) can output the data of the (N + 2)A data line (e.g., the 402A data line) and the (N + 2)B data line (e.g., the 402B data line), the (N + 7)th output amplifier (e.g., Y407) outputs the data of the (N + 3)A data line (e.g., the 403A data line) and the (N + 3)B data line (e.g., the 403B data line), and the (N + 8)th output amplifier (e.g., Y408) outputs the data of the (N + 4)A data line (e.g., the 404A data line) and the (N + 4)B data line (e.g., the 404B data line). The (N + 6)th output amplifier (e.g., Y406), the (N + 7)th output amplifier (e.g., Y407), and the (N + 8)th output amplifier (e.g., Y408) can all output normal data.
[0136] According to this embodiment, since it includes a demultiplexer switch structure that supports 4-wire bundles and a wiring mixing structure for preventing data mapping errors, the demultiplexing coupling can be improved and data mapping errors can be prevented.
[0137] Moreover, without changing the integrated circuit of the data driving unit 500 and the active area of the display panel 100, a demultiplexer switch structure that supports 4-wire bundles can be supported.
[0138] In addition, since the data driving unit 500 is configured to have a boundary reduction structure that can cross-output the data voltage applied to the data lines in the central portion of the display panel 100 and the data voltage applied to the data lines at the edge of the display panel, the ineffective space of the display device can be reduced.
[0139] In addition, since the demultiplexer circuit is disposed adjacent to the integrated circuit region on the second side of the curved line, the ineffective space of the display device can be further reduced.
[0140] In addition, by including a configuration of the data driving unit 500 for applying dummy data to the dummy data lines DM, appropriate data can be applied to the dummy data lines.
[0141] Figure 10 is a block diagram of an electronic device showing an embodiment of the present invention. Figure 11 shows Figure 10 An example in which the electronic device is implemented by a smartphone.
[0142] Referring to Figure 10 and Figure 11 , the electronic device 1000 may include: a processor 1010, a memory device 1020, a storage device 1030, an input / output device 1040, a power supply device 1050, and a display device 1060. At this time, the display device 1060 may be Figure 1 the display device. In addition, the electronic device 1000 may further include various ports that can communicate with a graphics card, a sound card, a memory card, a USB device, etc., or communicate with other systems.
[0143] According to an embodiment, as Figure 11 shown, the electronic device 1000 may be implemented by a smartphone. However, this is merely illustrative, and the electronic device 1000 is not limited thereto. For example, the electronic device 1000 may be implemented as a mobile phone, a video phone, a smart tablet, a smart watch, a tablet PC, a vehicle navigation, a computer monitor, a notebook, a head-mounted display device, etc.
[0144] The processor 1010 may perform specific calculations or tasks. According to an embodiment, the processor 1010 may be a microprocessor, a central processing unit, an application processor, etc. The processor 1010 may be connected to other components through an address bus, a control bus, a data bus, etc. According to an embodiment, the processor 1010 may also be connected to an expansion bus such as a Peripheral Component Interconnect (PCI) bus.
[0145] The processor 1010 may output the input image data IMG and the input control signal CONT to Figure 1 the driving control unit 200 thereof.
[0146] The memory device 1020 may store data required for the operation of the electronic device 1000. For example, the memory device 1020 may include non-volatile memory devices such as an Erasable Programmable Read-Only Memory (EPROM) device, an Electrically Erasable Programmable Read-Only Memory (EEPROM) device, a flash memory device, a Phase Change Random Access Memory (PRAM) device, a Resistance Random Access Memory (RRAM) device, a Nano Floating Gate Memory (NFGM) device, a Polymer Random Access Memory (PoRAM) device, a Magnetic Random Access Memory (MRAM), a Ferroelectric Random Access Memory (FRAM) device, etc. and / or volatile memory devices such as a Dynamic Random Access Memory (DRAM) device, a Static Random Access Memory (SRAM) device, a mobile DRAM device, etc.

The power supply device 1050 may supply power required for the operation of the electronic device 1000. The display device 1060 may be connected to other components via the bus or other communication links.
[0148] Figure 12 is a block diagram of an electronic device 101 showing an embodiment of the present invention.
[0149] Refer toFigures 1 to 12 The electronic device 101 outputs various information through the display module 140 within the operating system. When the processor 110 runs the application programs stored in the memory 120, the display module 140 provides the application program information to the user through the display panel 141.
[0150] The processor 110 obtains external inputs through the input module 130 or the sensing module 161 and runs the application programs corresponding to the external inputs. For example, in the case where the user selects the camera icon displayed on the display panel 141, the processor 110 obtains the user input through the input sensor 161-2 and activates the camera module 171. The processor 110 transfers the video data corresponding to the captured image obtained through the camera module 171 to the display module 140. The display module 140 may display the image corresponding to the captured image through the display panel 141.
[0151] As another example, in the case where personal information authentication is performed in the display module 140, the fingerprint sensor 161-1 obtains the input fingerprint information as input data. The processor 110 compares the input data obtained through the fingerprint sensor 161-1 with the authentication data stored in the memory 120 and runs the application program according to the comparison result. The display module 140 may display the information that runs according to the logic of the application program through the display panel 141.
[0152] As another example, in the case where the music stream icon displayed on the display module 140 is selected, the processor 110 obtains the user input through the input sensor 161-2 and activates the music stream application program stored in the memory 120.
