[0054] According to an embodiment, the direction perpendicular to the front surface corresponds to the thickness direction DR3 of the display device EA (hereinafter, referred to as the third direction DR3). In this embodiment, the front surface (or upper surface) and the rear surface (or lower surface) of each member are defined with reference to the direction in which the image IM is displayed.

[0060] In the present embodiment, the active area AA is an area where the image IM is displayed and is also an area where the external input TC is detected. However, this is a non-limiting example, and the area where the image IM is displayed in the active area AA and the area where the external input TC is detected in the active area AA may be separated from each other, and the display panel EP is not limited to any one embodiment.

[0062] In an embodiment, a flat display panel EP is assembled, wherein the active area AA and the peripheral area NAA face the window member WM. However, this is a non-limiting example, and a portion of the peripheral area NAA of the display panel EP may be bent. According to an embodiment, a portion of the peripheral area NAA is bent backward toward the rear surface of the display device EA, which reduces the border area BZA at the front surface of the display device EA. According to another embodiment, the display panel EP is assembled in a state where a portion of the active area AA is bent. Optionally, in the display panel EP according to another embodiment of the inventive concept, the peripheral area NAA is omitted.

[0063] According to an embodiment, the edge of the hole area HA is surrounded by the active area AA. In a plane, the hole area HA is spaced apart from the peripheral area NAA, and the active area AA is interposed therebetween.

[0064] According to the embodiment, the hole area HA where the module hole MH is formed penetrates the display panel EP in the third direction DR3. Therefore, the module hole MH is surrounded by the active area AA on a plane.

[0065] According to an embodiment of the inventive concept, at least one module hole MH is formed on the display panel EP. The module hole MH is a through hole that connects the front surface of the display panel EP to the rear surface. The component overlapped with the module hole MH disposed on the rear surface of the display panel EP can be viewed through the module hole MH from the front surface of the display panel EP. On the other hand, in the embodiment, although the module hole MH is shown as having a cylindrical shape extending in the third direction DR3, the shape of the module hole MH is not limited thereto, and the module hole MH may have various other shapes such as a polygonal column, an elliptical column, a cone, etc., without being limited to any one embodiment.

The image IM displayed by the active area AA of the display panel EP can be viewed from the outside through the transmission area TA.

[0069] According to an embodiment, the bezel area BZA has a low light transmittance compared to the transmission area TA. The bezel area BZA determines the shape of the transmission area TA. The bezel area BZA is adjacent to the transmission area TA and may surround the transmission area TA.

[0070] According to an embodiment, the bezel area BZA has a predetermined color. The bezel area BZA covers the peripheral area NAA of the display panel EP to prevent the peripheral area NAA from being visible outside. On the other hand, this is an example, and in the window member WM according to an embodiment of the inventive concept, the bezel area BZA may be omitted.

[0071] According to an embodiment, the case member BM may be combined with the window member WM. The case member BM provides a rear surface of the display device EA. The case member BM combined with the window member WM defines an internal space.

[0072] According to an embodiment, the shell member BM includes a high-hardness material. For example, the shell member BM includes a plurality of frames or plates made of glass, plastic, or metal. The shell member BM stably protects the structure of the display device EA accommodated in the internal space from external impact.

Some modules may not be mounted on the main board but may be electrically connected to the main board through a flexible circuit board.

[0076] According to an embodiment, the control module CM controls the overall operation of the display device EA. The control module CM may be a microprocessor. For example, the control module CM activates or deactivates the display panel EP. The control module CM controls other modules such as the image input module IIM or the audio input module AIM based on a touch signal received from the display panel EP.

[0077] According to an embodiment, the wireless communication module TM uses a Bluetooth or Wi-Fi line to send / receive a wireless signal to / from another terminal. The wireless communication module TM uses a general communication line to send / receive a voice signal. The wireless communication module TM includes: a transmitting unit TM1 that modulates and transmits a signal; and a receiving unit TM2 that demodulates the received signal.

[0078] According to an embodiment, the image input module IIM processes an image signal and converts it into image data that can be displayed on the display panel EP.

[0079] According to an embodiment, the external interface IF is used as an interface for an external charger, a wired / wireless data port, or a card slot such as a memory card, a SIM / UIM card, or the like.

[0080] According to an embodiment, the second electronic module EM2 includes an audio output module AOM, a light emitting module LM, a light receiving module LRM and a camera module CMM. The module can be directly mounted on the main board, or mounted on a separate substrate and electrically connected to the display panel EP or the first electronic module EM1 through a connector.

[0081] According to an embodiment, the audio output module AOM converts audio data received from the wireless communication module TM or converts audio data stored in the memory MM and outputs the audio data as sound.

[0082] According to an embodiment, the light emitting module LM generates and outputs light. The light emitting module LM outputs infrared light. The light emitting module LM includes an LED element. The light receiving module LRM detects the infrared light. When infrared light of a predetermined frequency or higher is detected, the light receiving module LRM is activated. The light receiving module LRM includes a CMOS sensor. After the infrared light generated by the light emitting module LM is emitted, the infrared light is reflected by an external object such as a user's finger or face, and the reflected infrared light is incident on the light receiving module LRM. The camera module CMM captures an image of the outside.

[0083] According to an embodiment, Figure 2 The electronic module EM shown in the figure receives an external input TC transmitted through the module hole MH, or can provide an output through the module hole MH. The electronic module EM can be any one of the modules in the first electronic module EM1 and the second electronic module EM2. For example, the electronic module EM can be a camera, a speaker, or a detection sensor of light or heat. The electronic module EM can detect an external object through the module hole MH or output a sound signal such as voice through the module hole MH. According to an embodiment, the remaining components of the first electronic module EM1 and the second electronic module EM2 can be arranged at different positions. However, this is an example, and the electronic module EM can include a plurality of modules constituting the first electronic module EM1 and the second electronic module EM2, without being limited to any one embodiment. In addition, the display device EA according to an embodiment of the inventive concept further includes a transparent member arranged between the electronic module EM and the display panel EP. The transparent member is an optically transparent film that transmits the external input TC to the electronic module EM through the module hole MH. The transparent member can be attached to the rear surface of the display panel EP, or can be arranged between the display panel EP and the electronic module EM without a separate adhesive layer. The display device EA according to an embodiment of the inventive concept can have various structures, without being limited to any one embodiment.

[0084] According to an embodiment, the display panel EP includes a module hole MH, so that a separate space for the electronic module EM outside the peripheral area NAA can be omitted. In addition, by forming the module hole MH in the hole area HA surrounded by the active area AA, the electronic module EM overlaps the transmissive area TA instead of the frame area BZA. Therefore, the area of ​​the frame area BZA is reduced, and a display device EA with a narrow frame can be implemented. In addition, when the electronic module EM is accommodated in the module hole MH, a thinner display device EA can be implemented.

[0142] According to an embodiment, the driving signal line CL and the initialization voltage line VIN are disposed on the same layer and simultaneously formed by the same process. However, this is an example, and the driving signal line CL and the initialization voltage line VIN may be independently formed by separate processes without being limited to any one embodiment.

[0143] According to an embodiment, the dams DM1 and DM2 are disposed in the peripheral area NAA. When the organic layer OL of the sealing layer DP-E is formed, the dams DM1 and DM2 prevent the organic layer OL from flowing out from the active area AA toward the edge of the display panel EP in the second direction DR2. The dams DM1 and DM2 are disposed adjacent to at least one side of the active area AA. The dams DM1 and DM2 surround the active area AA on a plane.

[0144] According to an embodiment, the first dam portion DM1 is disposed closer to the active area AA than the second dam portion DM2. The first dam portion DM1 overlaps the power line E-VSS.

[0145] In an embodiment, the first dam DM1 includes the same material as the fourth insulating layer 40 and is formed simultaneously with the fourth insulating layer 40 through one mask. Therefore, a separate process for forming the first dam DM1 may be omitted, which simplifies the process and reduces the process cost.

[0146] According to an embodiment, the second dam portion DM2 is disposed at the outer side of the first dam portion DM1. The second dam portion DM2 covers a portion of the power line E-VSS.

The first layer DM2-L1 is formed simultaneously with the third insulating layer 30, and the second layer DM2-L2 is formed simultaneously with the fourth insulating layer 40. Therefore, the second dam portion DM2 can be easily formed without requiring an additional process.

[0147] In the embodiment, the connection electrode E-CNT partially overlaps the first layer DM2-L1 of the second dam portion DM2. The end of the connection electrode E-CNT is inserted between the first layer DM2-L1 and the second layer DM2-L2.

[0157] According to an embodiment, the sensing touch lines RX1 to RX5 and the transmission touch lines TX1 to TX4 form a touch capacitor. The input detection unit ISU detects a touch input coordinate based on a change amount of the touch capacitor.

[0158] According to an embodiment, one end of each of the sensing lines RL1 to RL5 is connected to one end of each of the sensing touch lines RX1 to RX5. The other end of each of the sensing lines RL1 to RL5 is connected to the touch pad TPD. The sensing lines RL1 to RL5 transmit the sensing signals received from the sensing touch lines RX1 to RX5 to the touch driving chip through the touch pad TPD.

[0159] According to an embodiment, one end of each of the first to fourth transmission lines TL1 to TL4 of the transmission lines TL1 to TL8 is connected to one end of each of the transmission touch lines TX1 to TX4. The other end of each of the first to fourth transmission lines TL1 to TL4 may be connected to the touch pad TPD.

[0164] Figure 7 is along Figure 2 A cross-sectional view taken along line II-II'. Figure 8 and Fig. 9 yes Figure 2 Plan view of area XX' in . Figure 7 corresponds substantially to a cross-sectional view of region XX'. Figure 8 and Fig. 9In FIG. 1 , all components of the display panel EP are not shown. Specifically, Figure 8 Some of the pixels PX and signal lines are shown, Fig. 9 The input detection unit ISU (see Figure 6 ). In the following, reference will be made to Figures 7 to 9 Embodiments of the inventive concept are described.

[0165] According to an embodiment, the hole area HA is surrounded by the active area AA in a plane. Figure 7 and Figure 8 , for ease of explanation, the hole area HA is shown by a dotted line. The pixels PX are spaced apart from the module hole MH, and some of the pixels PX disposed adjacent to the hole area HA are disposed along an edge of the hole area HA.

[0166] Reference Figure 7 According to an embodiment, the module hole MH is formed in the hole area HA. ​​The module hole MH is formed at the center of the hole area HA. ​​The module hole MH is a through hole that penetrates the display panel EP. The module hole MH penetrates the base substrate BSS (see FIG. Figure 5 ). Specifically, the module hole MH penetrates the structure disposed in the hole area HA in the layer disposed on the front surface of the base substrate BSS. Therefore, the first insulating layer 10, the second insulating layer 20, the third insulating layer 30, the fourth insulating layer 40, the first inorganic layer 10L1 and the second inorganic layer 10L2 extending to the hole area HA are penetrated to form the side surface of the module hole MH.

[0167] In addition, the display panel EP according to the present embodiment further includes a recessed pattern GV formed in the hole area HA. ​​The recessed pattern GV is formed along the edge of the module hole MH. Figure 8 , is shown as a closed loop surrounding the module hole MH and having a shape similar to that of the module hole MH. However, this is an example. The recessed pattern GV may have a shape different from that of the module hole MH (such as a polygon, an ellipse, or a closed curve including at least a portion of a circle), or have a shape including a plurality of partially disconnected patterns, but the shape of the recessed pattern GV is not limited to any one embodiment.

[0168] According to an embodiment, the recessed pattern GV is formed by removing some components of the display panel EP to form a recessed pattern in the front surface of the display panel EP. On the other hand, unlike the module hole MH, the recessed pattern GV does not penetrate the display panel EP. Therefore, the rear surface of the base substrate BSS overlaps with the recessed pattern GV and is not opened by the recessed pattern GV.

[0169] According to an embodiment, the recessed pattern GV penetrates into the base layer BS and penetrates the remaining components. In an embodiment, the recessed pattern GV is formed by connecting a through portion formed in the auxiliary layer BL and a recessed portion formed in the base layer BS. The inner surface of the recessed pattern GV is covered by the first inorganic layer IOL1 and the second inorganic layer IOL2.

[0170] On the other hand, according to an embodiment, the recessed pattern GV has an undercut shape including a tip portion TP protruding inward. In an embodiment, the tip portion TP is a portion of the auxiliary layer BL that protrudes further toward the other side of the recessed pattern GV than the base layer BS. On the other hand, if the tip portion TP is formed in the recessed pattern GV, the display panel EP according to an embodiment of the inventive concept may have various layer structures and is not limited to any one embodiment.

[0171] According to an embodiment, the display panel EP further includes a predetermined organic pattern EL-P disposed in the recessed pattern GV. The organic pattern EL-P includes the same material as that of the control layer EL. Optionally, the organic pattern EL-P further includes the same material as that of the second electrode E2. The organic pattern EL-P may have a single-layer structure or a multi-layer structure.

[0172] According to an embodiment, the organic pattern EL-P is disposed in the recessed pattern GV, which is spaced apart from the control layer EL and the second electrode E2. The organic pattern EL-P is covered by the first inorganic layer IOL1 and is not exposed to the outside.

[0173] According to an embodiment, the recessed pattern GV destroys the continuity of the control layer EL extending from the side surface of the module hole MH to the active area AA. The control layer EL is disconnected in the area overlapping with the recessed pattern GV. The control layer EL can be a path for the movement of external contamination such as moisture or air. Moisture or air may be introduced through a path extending from a layer exposed by the module hole MH (such as the control layer EL), pass through the hole area HA and enter the active area AA. The path is blocked by the recessed pattern GV. Therefore, the reliability of the display panel EP having the module hole MH can be improved.

[0174] In addition, in the display panel EP according to the embodiment of the inventive concept, a plurality of recessed patterns GV may be provided spaced apart from each other in a radial direction with respect to the center of the module hole MH, and a portion of the organic layer OL extends to fill a portion of the recessed pattern GV. Alternatively, in the display panel EP according to the embodiment of the inventive concept, the recessed pattern GV may be omitted, and the recessed pattern GV is not limited to any one embodiment.

[0175] According to the embodiment, as described above, the pixel PX and the input detection unit ISU are disposed spaced apart from the module hole MH on the plane. Figure 8and Fig. 9 The module hole MH and the pixels PX and the input sensing unit ISU around the module hole MH are described.

[0176] Refer again Figure 7 According to an embodiment, a routing area RA is further defined in the hole area HA. ​​The routing area RA is located outside the module hole MH. Specifically, the routing area RA is outside the recessed pattern GV. The routing area RA surrounds the module hole MH and the recessed pattern GV.

[0177] Reference Figure 8 According to an embodiment, the pixels PX are arranged around the hole area HA. ​​Some pixels PX are arranged along the edge of the hole area HA. ​​The pixels PX are spaced apart from the module hole MH on a plane.

[0178] According to an embodiment, a plurality of signal lines SL1, SL2, SL3, and SL4 connected to the pixel PX are disposed in the hole area HA. ​​The signal lines SL1, SL2, SL3, and SL4 are connected to the pixel PX through the routing area RA. For ease of explanation, Figure 8 A first signal line SL1 , a second signal line SL2 , a third signal line SL3 , and a fourth signal line SL4 among a plurality of signal lines connected to the pixel PX are shown.

[0179] According to an embodiment, in the active area AA, the first signal line SL1 extends along the first direction DR1. The first signal line SL1 is connected to the pixels PX arranged in the same column along the first direction DR1. The first signal line SL1 corresponds to the data line 16 (see Figure 4 ).

[0180] According to an embodiment, in the routing area RA, the first signal line SL1 has a meander shape. Figure 8 The first signal line SL1 is shown to form a semicircular shape in the routing area RA along the outlines of the module hole MH and the recess pattern GV.

[0181] According to an embodiment, some of the pixels PX connected to the first signal line SL1 are arranged on the upper side of the module hole MH, and other of the pixels PX connected to the first signal line SL1 are arranged on the lower side of the module hole MH. Therefore, even if some pixels PX around the module hole MH are omitted, the pixels PX in the same column connected to the first signal line SL1 receive data signals through the same line.

[0182] According to an embodiment, in the active area AA, the second signal line SL2 extends along the second direction DR2. The second signal line SL2 is connected to the pixels PX arranged in the same row along the second direction DR2. The second signal line SL2 corresponds to the first scan line 14 (see Figure 4 ).

[0184] In the routing area RA, some of the pixels PX connected to the second signal line SL2 are arranged on the left side of the module hole MH, while other pixels PX connected to the second signal line SL2 are arranged on the right side of the module hole MH. Therefore, even if some pixels PX around the module hole MH are omitted, the pixels PX in the same row connected to the second signal line SL2 are still turned on / off by substantially the same gate signal.

Figure 4 As described, the sensing touch sensor unit SP2, the transmission touch sensor unit SP1, and the second connection part CP2 are arranged on the same layer, and the first connection part CP1 is arranged on another layer. Since the second connection part CP2 and the first connection part CP1 are arranged on different layers, they can be electrically insulated even if they cross each other on the plane. The second connection part CP2 is directly connected to the sensing touch sensor unit SP2, and the first connection part CP1 is connected to the transmission touch sensor unit SP1 through the contact hole CH1.

[0193] Furthermore, in the present embodiment, some of the sensing touch sensor units SP2 and the transmitting touch sensor units SP1 are disconnected due to the module hole MH.

[0194] According to an embodiment, some of the transmission touch sensor units SP1 are divided into upper and lower parts around the module hole MA.

However, embodiments of the inventive concept are not limited thereto, and the second bridge line BL2 and the first bridge line BL1 may be formed by the first mesh line MSL1 and the second mesh line MSL2.

Therefore, even if the module hole MH is formed in the active area AA, the display panel EP can provide stable driving of the active area AA.

[0202] Furthermore, by arranging the bridge lines BL1 and BL2 in the routing area RA in the hole area HA, the quality of an image displayed by the pixel PX can be maintained, and the bridge lines BL1 and BL2 are not externally visible, which can improve the display quality.
