[0075] The sixth pixel switching element T6 includes a control electrode to which an emission signal EM is applied, an input electrode connected to the third node N3, and an output electrode connected to the anode electrode of the organic light-emitting element OLED.

[0076] In one or more example embodiments, the sixth pixel switching element T6 may be a polysilicon thin-film transistor.

The control electrode of the seventh pixel switching element T7 may be a gate electrode, the input electrode of the seventh pixel switching element T7 may be a source electrode, and the output electrode of the seventh pixel switching element T7 may be a drain electrode.

[0079] Although the seventh pixel switching element T7 is an oxide thin-film transistor in the illustrated example embodiment, the inventive concept is not limited thereto. For example, the seventh pixel switching element T7 could be a polysilicon thin-film transistor. Although the seventh pixel switching element T7 is an N-type thin-film transistor in the illustrated example embodiment, the inventive concept is not limited thereto. For example, the seventh pixel switching element T7 could be a P-type thin-film transistor.

[0080] The storage capacitor CST includes a first electrode to which a high electrical voltage ELVDD is applied and a second electrode connected to a first node N1.

[0081] Organic light-emitting elements (OLEDs) include an anode electrode and a cathode electrode to which a low electrical voltage (ELVSS) is applied.

[0082] exist Figure 3 During the first duration DU1, the first node N1 and the storage capacitor CST are initialized in response to the data initialization gate signal GI (e.g., the data initialization gate signal GI is applied high to the control electrode of the fourth pixel switching element T4). During the second duration DU2, the threshold voltage |VTH| of the first pixel switching element T1 is compensated in response to the first data write gate signal GWP and the second data write gate signal GWN (e.g., the first data write gate signal GWP is applied low to the control electrode of the second pixel switching element T2, and the second data write gate signal GWN is applied high to the control electrode of the third pixel switching element T3), and the data voltage VDATA compensated for the threshold voltage |VTH| is written to the first node N1. During the third duration DU3, the anode electrode of the organic light-emitting element OLED is initialized in response to the organic light-emitting element initialization gate signal GB (e.g., the organic light-emitting element initialization gate signal GB is applied high to the control electrode of the seventh pixel switching element T7). During the fourth duration DU4, the organic light-emitting element OLED emits light in response to the emission signal EM (e.g., the emission signal EM is applied at a low level to the control electrode of the fifth pixel switching element T5 and the control electrode of the sixth pixel switching element T6), causing the display panel 100 to display an image.

[0083] Although in the illustrated example embodiment, the transmit-off duration of the transmit signal EM corresponds to the first to third durations (first duration DU1, second duration DU2, and third duration DU3), the inventive concept is not limited thereto. The transmit-off duration of the transmit signal EM may be configured to include the second duration DU2. In one or more example embodiments, the transmit-off duration of the transmit signal EM may be longer than the sum of the first to third durations DU1, DU2, and DU3.

[0084] During the first duration DU1, the data initialization gate signal GI can have an active level. For example, the active level of the data initialization gate signal GI can be a high level. When the data initialization gate signal GI has an active level, the fourth pixel switch element T4 is turned on, allowing the initialization voltage VI to be applied to the first node N1. The current stage's data initialization gate signal GI[N] can be generated based on the previous stage's scan signal SCAN[N-1].

[0085] During the second duration DU2, the first data write gate signal GWP and the second data write gate signal GWN can have active levels. For example, the active level of the first data write gate signal GWP can be low, and the active level of the second data write gate signal GWN can be high. When the first data write gate signal GWP and the second data write gate signal GWN have active levels, the second pixel switch element T2 and the third pixel switch element T3 are turned on. In addition, the first pixel switch element T1 is turned on in response to the initialization voltage VI. The first data write gate signal GWP[N] of the current stage can be generated based on the scan signal SCAN[N] of the current stage. The second data write gate signal GWN[N] of the current stage can be generated based on the scan signal SCAN[N] of the current stage.

[0086] The voltage generated by subtracting the absolute value |VTH| of the threshold voltage of the first pixel switching element T1 from the data voltage VDATA can be charged at the first node N1 along the path generated from the first pixel switching element to the third pixel switching element (i.e., the first pixel switching element T1, the second pixel switching element T2, and the third pixel switching element T3).

[0087] During the third duration DU3, the OLED initialization gate signal GB can have an active level. For example, the active level of the OLED initialization gate signal GB can be a high level. When the OLED initialization gate signal GB has an active level, the seventh pixel switch element T7 is turned on, allowing the initialization voltage VI to be applied to the anode electrode of the OLED. The current stage's OLED initialization gate signal GB[N] can be generated based on the next stage's scan signal SCAN[N+1].

[0088] During the fourth duration DU4, the transmitted signal EM can have an active level. The active level of the transmitted signal EM can be low. When the transmitted signal EM has an active level, the fifth pixel switch element T5 and the sixth pixel switch element T6 are turned on. In addition, the first pixel switch element T1 is turned on by the data voltage VDATA.

[0089] A driving current flows through the fifth pixel switching element T5, the first pixel switching element T1, and the sixth pixel switching element T6 to drive the organic light-emitting element (OLED). The intensity of the driving current can be determined by the level of the data voltage VDATA. The brightness of the OLED is determined by the intensity (e.g., magnitude) of the driving current applied to the OLED.

[0090] In the illustrated example embodiment, when the image displayed on the display panel 100 is a static image or when the display panel 100 operates in normally-on mode, the driving frequency of the display panel 100 can be reduced to lower power consumption. When all the switching elements of the pixels of the display panel 100 are polysilicon thin-film transistors, flicker may occur due to leakage current of the pixel switching elements in low-frequency driving mode. Therefore, oxide thin-film transistors can be used to design some of the pixel switching elements. In the illustrated example embodiment, the third pixel switching element T3, the fourth pixel switching element T4, and the seventh pixel switching element T7 can be oxide thin-film transistors. The first pixel switching element T1, the second pixel switching element T2, the fifth pixel switching element T5, and the sixth pixel switching element T6 can be polysilicon thin-film transistors. Therefore, in the illustrated embodiment, flicker can be reduced or prevented in low-frequency driving mode.

[0091] Although in the illustrated example embodiment, the second data write gate signal GWN is applied to the control electrode of the third pixel switching element T3, and the organic light-emitting element initialization gate signal GB is applied to the control electrode of the seventh pixel switching element T7, the inventive concept is not limited thereto. The control electrode of the third pixel switching element T3 may be connected to the control electrode of the seventh pixel switching element T7, and the second data write gate signal GWN may be applied to both the control electrodes of the third pixel switching element T3 and the seventh pixel switching element T7. Therefore, in one or more example embodiments, the separate organic light-emitting element initialization gate signal GB may be omitted.

In one or more example embodiments, the first pixel P14 and the third pixel P34 among the pixels arranged in the fourth pixel column of the display panel 100 can be connected to the seventh data line DL7, and the second pixel P24 and the fourth pixel P44 among the pixels arranged in the fourth pixel column can be connected to the eighth data line DL8.

[0098] A hole HL can be arranged in the effective area AA. The hole HL can be formed to correspond to the position of the camera module of the display device. In one or more example embodiments, the hole HL can overlap with the camera module of the display device. The hole HL can refer to a hole physically formed in the substrate of the display panel 100. In one or more example embodiments, only transparent elements are arranged in the hole HL.

[0099] The display panel 100 may include multiple gate layers GAT1, GAT2 and GAT3 and multiple source-drain layers SD1 and SD2. The multiple gate layers GAT1, GAT2 and GAT3 include gate patterns extending in a first direction D1, and the multiple source-drain layers SD1 and SD2 include source-drain patterns extending in a second direction D2.

[0100] The gate patterns of gate layers GAT1, GAT2, and GAT3, which do not pass through the region where the aperture HL is formed (e.g., the region including the aperture HL), extend linearly in the first direction D1. In one or more example embodiments, when in such... Figure 6 When viewed in the plan view shown, the gate patterns of the second gate layer GAT2 and the third gate layer GAT3, which do not pass through the region where the aperture HL is formed, overlap. In one or more example embodiments, the gate patterns of gate layers GAT1, GAT2, and GAT3, which pass through the region where the aperture HL is formed (i.e., through the region including the aperture HL and the region surrounding the aperture HL), extend linearly in the first direction D1 in the normal region where the aperture HL is not formed, and the gate patterns of gate layers GAT1, GAT2, and GAT3 curl or bend along the periphery (e.g., outer periphery) of the aperture HL in the region surrounding the aperture (i.e., the region surrounding the aperture HL). In one or more example embodiments, the region surrounding the aperture is adjacent to (e.g., directly adjacent to) the aperture HL. In one or more example embodiments, the region surrounding the aperture borders the aperture HL.

[0101] The source-drain patterns of source-drain layers SD1 and SD2 that do not pass through the region where the aperture HL is formed (e.g., the region including the aperture HL) extend linearly in the second direction D2. In one or more example embodiments, the source-drain patterns of source-drain layers SD1 and SD2 that pass through the region where the aperture HL is formed (i.e., the region including the aperture HL and the region surrounding the aperture HL) extend linearly in the second direction D2 in the normal region where the aperture HL is not formed, and the source-drain patterns of source-drain layers SD1 and SD2 curl or bend along the periphery of the aperture HL in the region surrounding the aperture (i.e., the region surrounding the aperture HL).

[0102] In one or more example embodiments, when from Figure 6 When viewed in the plan view shown in the embodiment, the first source-drain layer SD1 and the second source-drain layer SD2 can extend in the normal region along the second direction D2 and be alternately arranged along the first direction D1. In one or more example embodiments, when viewed from... Figure 6 When viewed in the plan view shown in the embodiment, the first gate layer GAT1 and the third gate layer GAT3 can extend in the normal region along the first direction D1 and be alternately arranged along the second direction D2. In one or more example embodiments, when viewed from... Figure 6When viewed in the plan view shown in the embodiment, the first gate layer GAT1 and the second gate layer GAT2 can extend in the normal region in the first direction D1 and be alternately arranged in the second direction D2.

[0103] The portion of the gate patterns of gate layers GAT1, GAT2, and GAT3, or the source-drain patterns of source-drain layers SD1 and SD2, that is curled or bent due to the via HL, can be defined as the area around the via.

[0104] Figure 7 It is shown in the diagram along Figure 6 The cross-sectional view of the display panel 100 taken by line A-A'. Figure 8 It is shown in the diagram along Figure 6 The cross-sectional view of the display panel 100 taken by line B-B'. Figure 9 It is shown in the diagram along Figure 6 The cross-sectional view of the display panel 100 taken by line C-C'.

[0105] Line A-A' represents the cross-sectional structure of source-drain layers SD1 and SD2 in the normal region where the via HL is not formed. Line B-B' represents the cross-sectional structure of gate layers GAT1, GAT2, and GAT3 in the normal region where the via HL is not formed. Line C-C' represents the cross-sectional structure of gate layers GAT1, GAT2, and GAT3, and source-drain layers SD1 and SD2 in the region surrounding the via (i.e., the region around the via HL).

[0106] refer to Figures 1 to 9 The display panel 100 includes: a substrate layer PI, a barrier layer BR disposed on the substrate layer PI, a first gate insulating layer GI1 disposed on the barrier layer BR, a first gate layer GAT1 disposed on the first gate insulating layer GI1, a second gate insulating layer GI2 disposed on the first gate layer GAT1 and / or the first gate insulating layer GI1, a second gate layer GAT2 disposed on the second gate insulating layer GI2, a first passivation layer ILD1 disposed on the second gate layer GAT2 and / or the second gate insulating layer GI2, and a first passivation layer ILD1 disposed on the first passivation layer ILD1. The third gate layer GAT3 on LD1, the second passivation layer ILD2 disposed on the third gate layer GAT3 and / or the first passivation layer ILD1, the first source-drain layer SD1 disposed on the second passivation layer ILD2, the first organic insulating layer VIA1 disposed on the first source-drain layer SD1 and / or the second passivation layer ILD2, the second source-drain layer SD2 disposed on the first organic insulating layer VIA1, and the second organic insulating layer VIA2 disposed on the second source-drain layer SD2 and / or the first organic insulating layer VIA1.

[0107] The substrate layer PI may include polyimide. The barrier layer BR may include inorganic materials. The thickness of the barrier layer BR may be between approximately 800 nm and approximately 900 nm.

[0108] The first gate insulating layer GI1 and the second gate insulating layer GI2 may comprise inorganic materials. The thickness of the first gate insulating layer GI1 may be approximately 150 nm. The thickness of the second gate insulating layer GI2 may be approximately 150 nm.

[0109] The first passivation layer ILD1 and the second passivation layer ILD2 may comprise inorganic materials. The thickness of the first passivation layer ILD1 and the thickness of the second passivation layer ILD2 may be greater than the thickness of the first gate insulating layer GI1 and the thickness of the second gate insulating layer GI2. The thickness of the first passivation layer ILD1 may be between approximately 400 nm and approximately 500 nm. The thickness of the second passivation layer ILD2 may be between approximately 400 nm and approximately 500 nm.

[0110] The first organic insulating layer VIA1 and the second organic insulating layer VIA2 may comprise organic insulating materials. The thickness of the first organic insulating layer VIA1 and the thickness of the second organic insulating layer VIA2 may be greater than the thickness of the first gate insulating layer GI1 and the thickness of the second gate insulating layer GI2. The thickness of the first organic insulating layer VIA1 and the thickness of the second organic insulating layer VIA2 may be greater than the thickness of the first passivation layer ILD1 and the thickness of the second passivation layer ILD2. The thickness of the first organic insulating layer VIA1 may be between approximately 1.5 μm and approximately 2 μm. The thickness of the second organic insulating layer VIA2 may be between approximately 1.5 μm and approximately 2 μm.

[0111] In an example embodiment, the first passivation layer ILD1 can be replaced by a third gate insulating layer. In this document, the third gate insulating layer may comprise an inorganic material. The thickness of the third gate insulating layer may be approximately 150 nm.

[0112] like Figure 7 As shown, in the normal region, the first source-drain layer SD1 and the second source-drain layer SD2 may not overlap in the thickness direction.

[0113] The first source-drain layer SD1 may include Figure 4 The pixel structure includes odd-numbered data lines DL1, DL3, DL5, and DL7. The second source-drain layer SD2 may include... Figure 4 The even-numbered data lines DL2, DL4, DL6, and DL8 in the pixel structure. In the normal region, the odd-numbered data lines DL1, DL3, DL5, and DL7 can not overlap with the even-numbered data lines DL2, DL4, DL6, and DL8, so that the first source-drain layer SD1 and the second source-drain layer SD2 can not overlap in the thickness direction in the normal region.

[0114] On the contrary, such as Figure 9As shown, in the region surrounding the aperture, the first source-drain layer SD1 and the second source-drain layer SD2 may overlap in the thickness direction. In the region surrounding the aperture, the first source-drain layer SD1 and the second source-drain layer SD2 are not connected to pixels. According to one or more example embodiments, the patterns on the first source-drain layer SD1 and the second source-drain layer SD2 are curled or bent in the region surrounding the aperture to bypass the aperture HL.

[0115] In the region surrounding the aperture, the first source-drain layer SD1 and the second source-drain layer SD2 can overlap in the thickness direction, thereby reducing the dead zone caused by (or defined by) the aperture HL.

[0116] The horizontal spacing of adjacent data lines on the first source-drain layer SD1 in the area surrounding the via can be smaller than the horizontal spacing of adjacent data lines on the first source-drain layer SD1 in the normal area. Similarly, the horizontal spacing of adjacent data lines on the second source-drain layer SD2 in the area surrounding the via can be smaller than the horizontal spacing of adjacent data lines on the second source-drain layer SD2 in the normal area. Therefore, the dead zone caused by the via HL can be further reduced in the area surrounding the via.

[0117] like Figure 8 As shown, in the normal region, the second gate layer GAT2 and the third gate layer GAT3 can overlap in the thickness direction, and in the normal region, the first gate layer GAT1 can not overlap with the second gate layer GAT2 and the third gate layer GAT3 in the thickness direction.

[0118] The first gate layer GAT1 may include outputting the P-type gate signal GWP to... Figure 2 The P-type gate line GWPL of the P-type transistor. The second gate layer GAT2 may include the back gate electrode of the P-type or N-type transistor and the connection line of the back gate electrode. The third gate layer GAT3 may include outputting the N-type gate signal GWN to Figure 2 The N-type gate line GWNL of the N-type transistor. In one or more example embodiments, the second gate layer GAT2 may include a memory electrode overlapping the first gate layer GAT1.

[0119] In the normal region, the first gate layer GAT1 and the second gate layer GAT2 can output gate signals with different waveforms. Therefore, it is desirable that the first gate layer GAT1 and the second gate layer GAT2 do not overlap in the thickness direction to prevent or reduce signal coupling. In other words, the first gate layer GAT1 and the second gate layer GAT2 can not overlap in the thickness direction to prevent or reduce the possibility of gate signal coupling.

[0120] On the contrary, such as Figure 9As shown, in the region surrounding the aperture, the first gate layer GAT1, the second gate layer GAT2, and the third gate layer GAT3 may overlap each other in the thickness direction. In the region surrounding the aperture, the patterns on the first gate layer GAT1, the second gate layer GAT2, and the third gate layer GAT3 are curled or bent to bypass the aperture HL.

[0121] In the region surrounding the aperture, the first gate layer GAT1, the second gate layer GAT2, and the third gate layer GAT3 can overlap each other in the thickness direction, thereby reducing the dead zone caused by the aperture HL.

[0122] The horizontal spacing of adjacent gate lines on the first gate layer GAT1 in the peri-hole region can be smaller than the horizontal spacing of adjacent gate lines on the first gate layer GAT1 in the normal region. The horizontal spacing of adjacent connection lines of the back gate electrode on the second gate layer GAT2 in the peri-hole region can be smaller than the horizontal spacing of adjacent connection lines of the back gate electrode on the second gate layer GAT2 in the normal region. The horizontal spacing of adjacent gate lines on the third gate layer GAT3 in the peri-hole region can be smaller than the horizontal spacing of adjacent gate lines on the third gate layer GAT3 in the normal region. Therefore, the dead zone caused by the via HL can be further reduced in the peri-hole region.

[0123] Furthermore, in the illustrated example embodiment, in the region surrounding the via, the first gate layer GAT1, the second gate layer GAT2, the third gate layer GAT3, the first source-drain layer SD1, and the second source-drain layer SD2 may overlap each other in the thickness direction. Therefore, the dead zone caused by the via HL can be further reduced in the region surrounding the via.

[0124] Despite Figure 9 As shown, the first gate layer GAT1, the second gate layer GAT2, the third gate layer GAT3, the first source-drain layer SD1, and the second source-drain layer SD2 may overlap each other in the thickness direction in the region around the via to reduce the dead zone caused by the via HL. However, in one or more example embodiments, one or more of the first gate layer GAT1, the second gate layer GAT2, the third gate layer GAT3, the first source-drain layer SD1, and the second source-drain layer SD2 may not overlap with other layers.

[0125] According to the example embodiment shown, when the hole HL is formed in the effective area AA of the display panel 100, and the patterns on the gate layers GAT1, GAT2 and GAT3 and the source-drain layers SD1 and SD2 bypass the hole HL in the area surrounding the hole, the patterns on the gate layers GAT1, GAT2 and GAT3 and the source-drain layers SD1 and SD2 overlap each other in the thickness direction, so that the dead zone adjacent to the area surrounding the hole can be reduced.

[0126] Figure 10This is a plan view illustrating a hole, a region surrounding the hole, and a normal region in a display panel according to an exemplary embodiment of the present invention. Figure 11 It is shown in the diagram along Figure 10 The cross-sectional view of the display panel is taken by line C-C'.

Figures 1 to 9 The display panel and display device including the previously described example embodiment are substantially the same, except for the layer structure of the display panel in the area surrounding the hole. Therefore, the same reference numerals will be used to refer to the same... Figures 1 to 9 The parts described in the previous example embodiments are the same or similar to the parts described above, and any repeated or redundant descriptions of the above elements may be omitted.

[0128] refer to Figures 1 to 5 , Figure 7 , Figure 8 , Figure 10 and Figure 11 The display device includes a display panel 100 and a display panel driver. The display panel driver includes a drive controller 200, a gate driver 300, a gamma reference voltage generator 400, a data driver 500, and a transmit driver 600.

[0129] The display panel 100 includes an effective area AA for displaying images and a peripheral area PA surrounding the effective area AA. An aperture HL can be arranged within the effective area AA. The aperture HL can be formed to correspond to the position of the camera module of the display device.

[0130] The display panel 100 may include multiple gate layers GAT1, GAT2 and GAT3 and multiple source-drain layers SD1 and SD2. The multiple gate layers GAT1, GAT2 and GAT3 include gate patterns extending in a first direction D1, and the multiple source-drain layers SD1 and SD2 include source-drain patterns extending in a second direction D2.

[0131] The display panel 100 includes: a substrate layer PI, a barrier layer BR disposed on the substrate layer PI, a first gate insulating layer GI1 disposed on the barrier layer BR, a first gate layer GAT1 disposed on the first gate insulating layer GI1, a second gate insulating layer GI2 disposed on the first gate layer GAT1 and / or the first gate insulating layer GI1, a second gate layer GAT2 disposed on the second gate insulating layer GI2, a first passivation layer ILD1 disposed on the second gate layer GAT2 and / or the second gate insulating layer GI2, a third gate layer GAT3 disposed on the first passivation layer ILD1, a second passivation layer ILD2 disposed on the third gate layer GAT3 and / or the first passivation layer ILD1, a first source-drain layer SD1 disposed on the second passivation layer ILD2, a first organic insulating layer VIA1 disposed on the first source-drain layer SD1 and / or the second passivation layer ILD2, a second source-drain layer SD2 disposed on the first organic insulating layer VIA1, and a second organic insulating layer VIA2 disposed on the second source-drain layer SD2 and / or the first organic insulating layer VIA1.

[0132] like Figure 11 As shown, the display panel 100 may further include a third organic insulating layer VIA3 disposed only in the area around the hole and disposed between the second gate insulating layer GI2 and the second gate layer GAT2.

[0133] The first organic insulating layer VIA1, the second organic insulating layer VIA2, and the third organic insulating layer VIA3 may comprise organic insulating materials. The thicknesses of the first organic insulating layer VIA1, the second organic insulating layer VIA2, and the third organic insulating layer VIA3 may be greater than the thicknesses of the first gate insulating layer GI1 and the second gate insulating layer GI2. The thicknesses of the first organic insulating layer VIA1, the second organic insulating layer VIA2, and the third organic insulating layer VIA3 may be greater than the thicknesses of the first passivation layer ILD1 and the second passivation layer ILD2. The thickness of the first organic insulating layer VIA1 may be between approximately 1.5 μm and approximately 2 μm. The thickness of the second organic insulating layer VIA2 may be between approximately 1.5 μm and approximately 2 μm. The thickness of the third organic insulating layer VIA3 may be between approximately 1.5 μm and approximately 2 μm.

[0134] In the illustrated example embodiment, in the region surrounding the via, the first gate layer GAT1, the second gate layer GAT2, the third gate layer GAT3, the first source-drain layer SD1, and the second source-drain layer SD2 may overlap each other in the thickness direction. Therefore, the dead zone caused by the via HL can be reduced in the region surrounding the via.

[0135] The first gate layer GAT1 and the second gate layer GAT2 can output gate signals with different waveforms. In this case, it is desirable to reduce or prevent coupling between the first gate layer GAT1 and the second gate layer GAT2. Therefore, when the first gate layer GAT1 and the second gate layer GAT2 overlap each other in the thickness direction, coupling between the first gate layer GAT1 and the second gate layer GAT2 can occur. Therefore, as... Figure 11 As shown, a third organic insulating layer VIA3 may be formed between the first gate layer GAT1 and the second gate layer GAT2, thereby preventing or reducing coupling between the first gate layer GAT1 and the second gate layer GAT2. In one or more example embodiments, the third organic insulating layer VIA3 has a thickness sufficient to prevent or substantially prevent coupling between the first gate layer GAT1 and the second gate layer GAT2.

[0136] According to the example embodiment shown, when the hole HL is formed in the effective area AA of the display panel 100, and the patterns on the gate layers GAT1, GAT2 and GAT3 and the source-drain layers SD1 and SD2 bypass the hole HL in the area surrounding the hole, the patterns on the gate layers GAT1, GAT2 and GAT3 and the source-drain layers SD1 and SD2 overlap each other in the thickness direction, so that the dead zone adjacent to the area surrounding the hole can be reduced.

[0137] Figure 12 This is a cross-sectional view illustrating the area around the hole in a display panel according to an exemplary embodiment of the present invention.

[0138] A display panel according to the example embodiment shown, and a display device including the display panel and reference. Figures 1 to 9 The display panel and display device including the previously described example embodiment are substantially the same or similar, except for the layer structure of the display panel in the area surrounding the aperture. Therefore, the same reference numerals will be used to refer to... Figures 1 to 9 The parts described in the previous example embodiments are the same or similar to the parts described above, and any repeated or redundant descriptions of the above elements may be omitted.

[0139] refer to Figures 1 to 8 as well as Figure 12 The display device includes a display panel 100 and a display panel driver. The display panel driver includes a drive controller 200, a gate driver 300, a gamma reference voltage generator 400, a data driver 500, and a transmit driver 600.

[0140] The display panel 100 includes an effective area AA for displaying images and a peripheral area PA surrounding the effective area AA. An aperture HL can be arranged within the effective area AA. The aperture HL can be formed to correspond to the position of the camera module of the display device.

[0141] The display panel 100 may include multiple gate layers GAT1, GAT2 and GAT3 and multiple source-drain layers SD1 and SD2. The multiple gate layers GAT1, GAT2 and GAT3 include gate patterns extending in a first direction D1, and the multiple source-drain layers SD1 and SD2 include source-drain patterns extending in a second direction D2.

[0142] The display panel 100 includes: a substrate layer PI, a barrier layer BR disposed on the substrate layer PI, a first gate insulating layer GI1 disposed on the barrier layer BR, a first gate layer GAT1 disposed on the first gate insulating layer GI1, a second gate insulating layer GI2 disposed on the first gate layer GAT1 and / or the first gate insulating layer GI1, a second gate layer GAT2 disposed on the second gate insulating layer GI2, a first passivation layer ILD1 disposed on the second gate layer GAT2 and / or the second gate insulating layer GI2, a third gate layer GAT3 disposed on the first passivation layer ILD1, a second passivation layer ILD2 disposed on the third gate layer GAT3 and / or the first passivation layer ILD1, a first source-drain layer SD1 disposed on the second passivation layer ILD2, a first organic insulating layer VIA1 disposed on the first source-drain layer SD1 and / or the second passivation layer ILD2, a second source-drain layer SD2 disposed on the first organic insulating layer VIA1, and a second organic insulating layer VIA2 disposed on the second source-drain layer SD2 and / or the first organic insulating layer VIA1.

[0143] like Figure 8 As shown, in the normal region, the second gate layer GAT2 can overlap with the third gate layer GAT3 in the thickness direction, and in the normal region, the first gate layer GAT1 can not overlap with the second gate layer GAT2 and the third gate layer GAT3 in the thickness direction.

[0144] like Figure 12 As shown, in the region around the aperture, the second gate layer GAT2 may overlap with the third gate layer GAT3 in the thickness direction, and in the region around the aperture, the first gate layer GAT1 may not overlap with the second gate layer GAT2 and the third gate layer GAT3 in the thickness direction.

[0145] In the illustrated example embodiment, the second gate layer GAT2, the third gate layer GAT3, the first source-drain layer SD1, and the second source-drain layer SD2 may overlap each other in the thickness direction in the region surrounding the hole. Therefore, the dead zone caused by the hole HL can be reduced in the region surrounding the hole.

[0146] The first gate layer GAT1 and the second gate layer GAT2 output gate signals with different waveforms. In this case, it is desirable to prevent or reduce coupling between the first gate layer GAT1 and the second gate layer GAT2. In the example embodiment shown, the patterns on the first gate layer GAT1 and the second gate layer GAT2 can be arranged alternately, such that the distance between the patterns on the first gate layer GAT1 and the patterns on the second gate layer GAT2 can be greater than [missing information]. Figure 9 The distance between the pattern on the first gate layer GAT1 and the pattern on the second gate layer GAT2 in the vertically overlapping structure is considered. Therefore, coupling between the first gate layer GAT1 and the second gate layer GAT2 can be prevented or reduced.

[0147] According to the example embodiment shown, when the hole HL is formed in the effective area AA of the display panel 100, and the patterns on the gate layers GAT1, GAT2 and GAT3 and the source-drain layers SD1 and SD2 bypass the hole HL in the area around the hole, a portion of the patterns on the gate layers GAT2 and GAT3 and the source-drain layers SD1 and SD2 overlap each other in the thickness direction, thereby reducing the dead zone adjacent to the area around the hole.

[0148] Figure 13 This is a conceptual diagram illustrating the pixel structure of a display panel according to an exemplary embodiment of the present invention. Figure 14 It is a diagram. Figure 13 A cross-sectional view of the area surrounding the holes in the display panel.

[0149] The display surface and display device including the display panel according to the example embodiment shown are referenced. Figures 1 to 9 The display panel and display device including the previously described example embodiment are substantially the same, except for the pixel structure of the display panel and the layer structure of the display panel in the area surrounding the holes. Therefore, the same reference numerals will be used to refer to the same... Figures 1 to 9 The parts described in the previous example embodiments are the same or similar to the parts described above, and any repeated or redundant descriptions of the above elements may be omitted.

[0150] refer to Figures 1 to 3 , Figure 5 , Figure 8 , Figure 13 and Figure 14 The display device includes a display panel 100 and a display panel driver. The display panel driver includes a drive controller 200, a gate driver 300, a gamma reference voltage generator 400, a data driver 500, and a transmit driver 600.

[0151] The display panel 100 includes an effective area AA for displaying images and a peripheral area PA surrounding the effective area AA. An aperture HL can be arranged within the effective area AA. The aperture HL can be formed to correspond to the position of the camera module of the display device.

[0152] The display panel 100 may include multiple gate layers GAT1, GAT2 and GAT3 and a source-drain layer SD1. The multiple gate layers GAT1, GAT2 and GAT3 include a gate pattern extending in a first direction D1, and the source-drain layer SD1 includes a source-drain pattern extending in a second direction D2.

[0153] The display panel 100 includes: a substrate layer PI, a barrier layer BR disposed on the substrate layer PI, a first gate insulating layer GI1 disposed on the barrier layer BR, a first gate layer GAT1 disposed on the first gate insulating layer GI1, a second gate insulating layer GI2 disposed on the first gate layer GAT1 and / or the first gate insulating layer GI1, a second gate layer GAT2 disposed on the second gate insulating layer GI2, a first passivation layer ILD1 disposed on the second gate layer GAT2 and / or the second gate insulating layer GI2, a third gate layer GAT3 disposed on the first passivation layer ILD1, a second passivation layer ILD2 disposed on the third gate layer GAT3 and / or the first passivation layer ILD1, a source-drain layer SD1 disposed on the second passivation layer ILD2, and an organic insulating layer VIA1 disposed on the source-drain layer SD1 and / or the second passivation layer ILD2.

[0154] like Figure 13 As shown, the display panel 100 includes a plurality of pixels arranged in a matrix.

[0155] In the example embodiment shown, pixels in a pixel column can be connected to a single data line adjacent to that pixel column.

[0156] For example, pixels P11, P21, P31, and P41 arranged in the first pixel column of the display panel 100 can be connected to the first data line DL1. For example, pixels P12, P22, P32, and P42 arranged in the second pixel column of the display panel 100 can be connected to the second data line DL2. For example, pixels P13, P23, P33, and P43 arranged in the third pixel column of the display panel 100 can be connected to the third data line DL3. For example, pixels P14, P24, P34, and P44 arranged in the fourth pixel column of the display panel 100 can be connected to the fourth data line DL4.

[0157] Figure 14 The source-drain layer SD1 may include a first data line DL1, a second data line DL2, a third data line DL3, and a fourth data line DL4.

[0158] In the illustrated example embodiment, the first gate layer GAT1, the second gate layer GAT2, the third gate layer GAT3, and the source-drain layer SD1 may overlap each other in the thickness direction in the region surrounding the via. Therefore, the dead zone caused by the via HL can be reduced in the region surrounding the via.

[0159] According to the example embodiment shown, when the hole HL is formed in the effective area AA of the display panel 100, and the patterns on the gate layers GAT1, GAT2 and GAT3 and the source-drain layer SD1 bypass the hole HL in the area surrounding the hole, the patterns on the gate layers GAT1, GAT2 and GAT3 and the source-drain layer SD1 overlap each other in the thickness direction, so that the dead zone adjacent to the area surrounding the hole can be reduced.

[0160] According to aspects of the exemplary embodiments of the inventive concept described above, the dead zone around the holes in the effective area of ​​the display panel can be reduced.
