[0037] The present disclosure will now be described more fully hereinafter with reference to the accompanying drawings, in which preferred embodiments of the invention are shown. However, the present invention may be implemented in different forms and should not be construed as limited to the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure will be thorough and complete and will fully convey the scope of the invention to those skilled in the art.

[0038] It will also be understood that when a layer is referred to as being “on” another layer or substrate, it can be directly on the other layer or substrate, or intervening layers may also be present. Like reference numerals refer to like components throughout the specification.

[0039] The display device according to various exemplary embodiments of the present disclosure can be used as a display screen for various devices for presenting videos or still images or a stereoscopic display device, and the various devices include portable electronic devices such as mobile communication terminals, smart phones, tablet PCs, smart watches, and navigation devices, as well as devices such as televisions, laptops, monitors, electronic billboards, and devices for the Internet of Things.

[0040] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. In the following description, an organic light-emitting display device will be described as an example of a display device. However, it is to be understood that the present disclosure is not limited thereto. Without departing from the scope of the present disclosure, the display device according to the exemplary embodiments of the present disclosure may also be applied to other display devices such as a liquid crystal display device and a field emission display device. Throughout the drawings, the same reference numerals represent the same elements.

[0041] Figure 1 is a plan view of a display device according to an exemplary embodiment of the present disclosure. Figure 2 is a cross-sectional view of a portion of a display device according to an exemplary embodiment of the present disclosure.

[0042] The organic light emitting display device 1 may include a display panel 10. The display panel 10 may include a flexible substrate including a flexible polymer material such as polyimide. Therefore, the display panel 10 may be bent, curved, folded, or rolled.

[0043] The display panel 10 may include a main region MR and a panel bending region BD connected to one side of the main region MR. The display panel 10 may further include a sub region SR connected to the panel bending region BD and overlapping the main region MR in a thickness direction.

[0044] The area of ​​the display panel 10 where an image is displayed is defined as a display area DA. The area of ​​the display panel 10 where an image is not displayed is defined as a non-display area NDA. The display area DA of the display panel 10 is disposed in the main region MR. Other areas except the display area DA serve as the non-display area NDA of the display panel 10. In an exemplary embodiment, an edge portion of the display area DA in the main region MR and the entire panel bending area BD and the entire sub-region SR may be the non-display area NDA. However, it is to be understood that the present disclosure is not limited thereto. The panel bending area BD and / or the sub-region SR may also include the display area DA.

[0045] When viewed from the top, the main region MR may have a shape generally similar to that of the organic light-emitting display device 1. The main region MR may be a flat region located in one plane. However, it is to be understood that the present disclosure is not limited thereto. In addition to the edge (side) connected to the panel bending region BD, at least one edge of the main region MR may be bent to form a curved surface or may be bent at a right angle.

[0046] The display area DA of the display panel 10 may be disposed at the center of the main region MR. The display area DA is defined as an area for displaying an image. The display area DA may also be used as an element for detecting an external environment. That is, the display area DA may be used as an area for displaying an image and may also be used as an area for identifying a user's touch input or fingerprint. In an exemplary embodiment, the display area DA may have a flat shape. However, it is to be understood that the present disclosure is not limited thereto. The display area DA may be at least partially bent. In this case, in addition to the edge (side) connected to the panel bending area BD, at least one edge of the display area DA in the main region MR may be bent to form a curved surface or may be bent at a right angle.

[0047] In an exemplary embodiment, the display area DA may have a rectangular shape. For example, the display area DA may have a rectangular shape having a shorter side extending in a first direction dr1 and a longer side extending in a second direction dr2 intersecting the first direction dr1. However, it is to be understood that the present disclosure is not limited thereto. The display area DA may have a polygonal shape, a circular shape, or an irregular shape. As used herein, for ease of explanation, the horizontal direction in the accompanying drawings is defined as the first direction dr1, and the direction intersecting the first direction dr1 is defined as the second direction dr2. That is, the second direction dr2 may represent the vertical direction in the accompanying drawings. It should be noted that the exemplary embodiments of the present disclosure are not limited by the directions defined above, and the first direction dr1 and the second direction dr2 may be any relative directions intersecting each other.

[0048] The display area DA may include a plurality of pixels. Each pixel may include an emission layer and a circuit layer for controlling the amount of light emitted from the emission layer. The circuit layer may include various lines, electrodes, and at least one transistor. The emission layer may include an organic light-emitting material. The emission layer may be sealed by an encapsulation layer. The construction of each pixel will be described in detail later.

[0049] The display area DA may include a plurality of touch sensing electrodes. The plurality of touch sensing electrodes may include a driving electrode and a sensing electrode. The driving electrode and the sensing electrode may be disposed on the same layer, but are not limited thereto. The driving electrode and the sensing electrode may be disposed on different layers. The plurality of touch sensing electrodes may be disposed on the encapsulation layers 131a, 131b, and 131c (see Fig. 9 The touch sensing electrodes will be described later.

[0050] The non-display area NDA is defined as an area that is disposed outside the display area DA and does not display an image. In an exemplary embodiment, the non-display area NDA may be disposed outside the display area DA to surround the display area DA. However, it is to be understood that the present disclosure is not limited thereto. The shape of the display area DA and the shape of the non-display area NDA may be relatively designed. In an exemplary embodiment, the non-display area NDA may have a flat shape. However, it is to be understood that the present disclosure is not limited thereto. The non-display area NDA may have a shape that is at least partially bent.

[0051] In the main region MR, the non-display area NDA may be located around the display area DA. In the main region MR, the non-display area NDA may extend from the outer boundary of the display area DA to the edge of the display panel 10. In the non-display area NDA of the main region MR, a signal line for applying a signal to the display area DA or a driving circuit may be provided. The outermost black matrix may be (but not limited to) provided in the non-display area NDA of the main region MR.

[0052] Although not shown in the drawings, a speaker module, a microphone module, a camera module, a sensor module, etc. may be disposed in the non-display area NDA. In an exemplary embodiment, the sensor module may include at least one of a brightness sensor, a proximity sensor, an infrared sensor, and an ultrasonic sensor.

[0053] The panel bending area BD is connected to the main area MR. For example, the panel bending area BD may be connected to the shorter side of the main area MR. The width of the panel bending area BD may be smaller than the width of the main area MR (the width of the shorter side). The portion where the main area MR and the panel bending area BD meet may be cut into an L shape.

[0054] In the panel bending area BD, the display panel 10 may be bent downward in the thickness direction, that is, have a curvature in a direction away from the display surface. Although the panel bending area BD may have a constant radius of curvature, the present disclosure is not limited thereto. The panel bending area BD may have different radii of curvature for different segments. When the display panel 10 is bent in the panel bending area BD, the surface of the display panel 10 is turned over. Specifically, the upward-facing surface of the display panel 10 may be bent so that it faces outward in the panel bending area BD and then faces downward.

[0055] The sub-region SR extends from the panel bending region BD. After the display device has been bent, the sub-region SR may extend in a direction parallel to the main region MR. The sub-region SR may overlap the main region MR in the thickness direction of the display panel 10. The sub-region SR may overlap the non-display area NDA at the edge of the main region MR, or may overlap the display area DA of the main region MR.

[0056] The width of the sub-region SR may be (but is not limited to) equal to the width of the panel bending region BD.

[0057] The driving chip 20 may be disposed on the sub-region SR of the display panel 10. The driving chip 20 may include an integrated circuit for driving the display panel 10. In an exemplary embodiment, the integrated circuit may be, but is not limited to, a data driving integrated circuit that generates and provides a data signal. The driving chip 20 may be mounted on the display panel 10 in the sub-region SR. The driving chip 20 is mounted on a surface of the display panel 10 that is a display surface. When the panel bending region BD is bent and turned over as described above, the driving chip 20 is mounted on a surface of the display panel 10 that faces downward in the thickness direction, so that the upper surface of the driving chip 20 may face downward.

[0058] The driving chip 20 may be attached to the display panel 10 through an anisotropic conductive film or attached to the display panel 10 through ultrasonic bonding. In the horizontal direction, the width of the driving chip 20 may be smaller than the width of the display panel 10. The driving chip 20 is disposed at the center of the sub-region SR in the horizontal direction, and the left and right edges of the driving chip 20 may be spaced apart from the left and right edges of the sub-region SR, respectively.

[0059] Pad unit PD (see Figure 3 ) may be formed at an end of the sub-region SR of the display panel 10, and the display driving substrate 30 may be connected to the pad unit PD. The display driving substrate 30 may be a flexible printed circuit board or a flexible printed circuit film.

[0060] The signal line may be disposed in the sub-region SR, the panel bending region BD, and the main region MR of the display panel 10. The signal line may extend from the pad unit PD in the sub-region SR to the main region MR via the panel bending region BD. Some signal lines (eg, power lines SP and touch lines TP (see Figure 6 )) may extend from the end of the pad unit PD in the sub-region SR to the panel bending region BD, and in turn extend to the main region MR without passing through the driving chip 20. Some other signal lines (e.g., data signal lines) among the signal lines may extend from the end of the pad unit PD to the panel bending region BD through the driving chip 20, and in turn extend to the main region MR.

[0061] To cover the relatively large entire main region MR, some signal lines may fan out from the sub-region SR and / or the panel bending region BD toward the main region MR. Some signal lines bypassing the driving chip 20 may extend along the outside of the signal lines passing through the driving chip 20.

[0062] The signal line passing through the panel bending area BD is bent together with the panel, so the signal line is subjected to bending stress. This bending stress may cause the signal line to break or disconnect. In order to prevent this, the signal line passing through the panel bending area BD may be formed of a more flexible material. In addition, the signal line passing through the panel bending area BD may have a multi-path structure in which a plurality of line layers are electrically connected to each other through contacts in a vertical direction, so that even when one line layer is disconnected, the signal can be transmitted through another line layer electrically connected thereto.

[0063] In the following description, for convenience of explanation, an edge portion 10a which is a part of the non-display area NDA of the display panel 10 and adjacent to the pad unit PD and a remaining portion 10b which is a remaining portion of the display area DA of the display panel 10 and the non-display area NDA are defined.

[0064] Figure 3 is shown in more detail Figure 1 FIG. 1 is a diagram showing a layout of an edge portion 10a of a display panel. Figure 4 yes Figure 3 An enlarged view of a portion of FF1. Figure 5 yes Figure 3 An enlarged view of a portion of FF2. Figure 6 is along Figure 4 A cross-sectional view taken along line I1-I1'. Figure 7 is along Figure 5 A cross-sectional view taken along line I2-I2'.

[0065] Reference Figures 3 to 7 The display panel 10 may include a plurality of touch lines TP, a plurality of power lines SP, and a plurality of data lines DP. Here, the same reference numeral may represent a line unit or a line of the line unit, for example, "TP" may represent a touch line unit or a touch line of the touch line unit.

[0066] The display panel 10 includes a base substrate 101, first line layers DP1_1 to DP1_10 disposed on the base substrate 101, a first line insulating layer 210 disposed on the first line layers DP1_1 to DP1_10, second line layers SP1_1 to SP1_11 disposed on the first line insulating layer 210, a second line insulating layer 220 disposed on the second line layers SP1_1 to SP1_11, third line layers TP1_1 to TP1_10 disposed on the second line insulating layer 220, and a third line insulating layer 230 disposed on the third line layers TP1_1 to TP1_10. A buffer layer or another insulating layer may also be disposed between the base substrate 101 and the first line layers DP1_1 to DP1_10.

[0067] Each of the touch lines TP, each of the power lines SP, and each of the data lines DP may extend from a corresponding pad terminal (e.g., a data pad terminal unit, a power pad terminal unit, and a touch pad terminal unit) included in the pad unit PD. The pad unit PD may be disposed near one edge of the display panel 10 in the second direction dr2. In an exemplary embodiment, the pad unit PD may be disposed at the outermost side in the second direction dr2 and may include a pad terminal connected to the touch line TP. In addition, the pad unit PD may include a pad terminal connected to the power line SP and a pad terminal connected to the data line DP toward the inside.

[0068] The plurality of signal lines extending from the pad terminals may generally extend in the second direction dr2. On the other hand, among the plurality of signal lines extending from the pad terminals, the touch line TP and the power line SP may be arranged to generally overlap each other and may extend in the second direction dr2. The touch line TP and the power line SP may be insulated from each other where they overlap each other. The touch line TP and the power line SP may overlap each other in the sub-region SR and the panel bending region BD of the display panel 10.

[0069] The pad terminals may be spaced apart from each other in the first direction dr1. The touch line TP and the power line SP may be parallel to each other where they extend from the pad terminals. In order to arrange the touch line TP and the power line SP so that they generally overlap each other, the touch line TP may include a portion bent toward the power line SP.

[0070] Specifically, the plurality of signal lines may include a first touch line unit TP1, which is disposed at one side in the first direction dr1 and is adjacent to the pad unit PD in the second direction dr2. The plurality of signal lines may include a first power line unit SP1, a data line unit DP, a second touch line unit TP2, and a second power line unit SP2, which are spaced apart from the first touch line unit TP1 in this order in the first direction dr1. The touch line unit TP may include a first touch line unit TP1 and a second touch line unit TP2; and the power line unit SP may include a first power line unit SP1 and a second power line unit SP2.

[0071] The pad terminals may be formed on the same layer. The signal lines may be electrically connected to the first line layers DP1_1 to DP1_10 to the third line layers TP1_1 to TP1_10 through the pad terminals and the contact holes. For example, the data lines DP may be connected to the first line layers DP1_1 to DP1_10 through the contact holes, the power lines SP may be connected to the second line layers SP1_1 to SP1_11 through the contact holes, and the touch lines TP may be connected to the third line layers TP1_1 to TP1_10 through the contact holes.

[0072] The first line layers DP1_1 to DP1_10 to the third line layers TP1_1 to TP1_10 are sequentially stacked from the base substrate 101, and an insulating layer may be included between every two line layers. In other exemplary embodiments, the first line layers DP1_1 to DP1_10 may be formed on the same layer as the pad terminals. In this case, the first line layers DP1_1 to DP1_10 may be directly connected to the pad terminals without passing through the contact holes.

[0073] The first touch line unit TP1 may include a portion overlapping the first power line unit SP1. The second touch line unit TP2 may include a portion overlapping the second power line unit SP2, and may continuously extend in the second direction dr2 to include a portion overlapping the common electrode CE disposed in the main region MR.

[0074] The lines of the touch line unit TP extending in the second direction dr2 may fan out at the locations where they overlap with the common electrode CE in the non-display area NDA. In each of the first touch line unit TP1 and the second touch line unit TP2, the number of lines TP1a and TP2a fanned out toward one side in the first direction dr1 may be equal to the number of lines TP1b and TP2b fanned out toward the opposite side in the first direction dr1, respectively.

[0075] exist Figure 4In the example shown in FIG. 1 , the first touch line unit TP1 includes the first touch line TP1_1 to the tenth touch line TP1_10, the touch line TP extends from each pad terminal in the second direction dr2, the touch line TP includes a portion bent so that the touch line TP overlaps the first power line unit SP1, and extends along the second direction dr2 at the overlap of the touch line TP and the first power line unit SP1. The touch line TP may extend along the second direction dr2 until it reaches the common electrode CE provided in the main region MR. The first touch line TP1_1 to the fifth touch line TP1_5 may extend beyond one edge of the common electrode CE to extend along the second direction dr2, and may fan out generally toward one side in the first direction dr1. The sixth touch line TP1_6 to the tenth touch line TP1_10 may extend beyond one edge of the common electrode CE to extend along the second direction dr2, and may fan out generally toward the opposite side in the first direction dr1. The distance TPW1 between the first touch line TP1_1 and one edge of the common electrode CE may be equal to the distance TPW2 between the tenth touch line TP1_10 and the edge of the common electrode CE. In an exemplary embodiment, the distance TPW1 and the distance TPW2 may be equal to or greater than 72 μm.

[0076] When the touch line unit TP fans out as described above, the distance between the edge of the common electrode CE and the fanned-out touch line unit TP may be reduced. Therefore, the dead zone of the organic light emitting display device 1 may be reduced.

[0077] The third line layers TP1_1 to TP1_10 may be made of indium tin oxide (ITO), indium zinc oxide (IZO), zinc oxide (ZnO), indium oxide (In 2 O 3 ), indium gallium oxide (IGO), aluminum zinc oxide (AZO), silver (Ag), magnesium (Mg), aluminum (Al), platinum (Pt), palladium (Pd), gold (Au), nickel (Ni), neodymium (Nd), iridium (Ir), chromium (Cr), calcium (Ca), silicon (Si), sodium (Na), tungsten (W), or a combination thereof. In an exemplary embodiment, the third line layers TP1_1 to TP1_10 may include corresponding touch line units TP.

[0078] The lines of the power line unit SP may extend from the respective pad terminals in the second direction dr2 in the sub region SR and the panel bending region BD, and may be electrically connected to the first pixel electrode 121 of each pixel in the main region MR (see FIG. Fig. 9 ) and the second pixel electrode 123 (see Fig. 9 ) to supply a voltage signal. The second pixel electrode 123 may be electrically connected to an electrode of the light emitting element.

[0079] The power line unit SP may overlap the touch line unit TP in a specific area, in which the power line layer SP may be disposed between the data line layer DP and the touch line layer TP. An insulating layer may be disposed between the data line layer DP, the power line layer SP, and the touch line layer TP so that they are insulated from each other. The power line unit SP may be used to reduce the influence of the noise signal generated in the data line DP on the touch line TP and the influence of the noise signal generated in the touch line TP on the data line DP.

[0080] The second line layers SP1_1 to SP1_11 may be formed of a suitable conductive material such as molybdenum (Mo), nickel (Ni), chromium (Cr), tungsten (W), silver (Ag), gold (Au), titanium (Ti), copper (Cu), aluminum (Al) and neodymium (μl-Nd) or an alloy thereof, and may be composed of a double layer including Mo / Al-μl-Nd, Mo / Al, Ti / Al, etc. and / or a multilayer structure such as Mo / Al / Mo, Mo / Al-μl-Nd / Mo, Ti / Al / Ti and Ti / Cu / Ti. In addition, the second line layers SP1_1 to SP1_11 may be formed of silver nanowires. In an exemplary embodiment, the second line layers SP1_1 to SP1_11 may include corresponding power line units SP. In an exemplary embodiment, when viewed from the top, the data line unit DP may be arranged closer to the inside than the touch line unit TP and the power line unit SP, that is, farther away from the edge of the display device 1. The data line unit DP may extend from the pad terminal in the second direction dr2, and the data line unit DP continuously extending in the second direction dr2 may fan out at a location where it overlaps with the common electrode CE in the non-display area NDA. The data line unit DP may include a portion overlapping the touch line unit TP and the power line unit SP at its fan-out location. In an exemplary embodiment, the data line unit DP may be disposed on the lowest layer, i.e., closer to the base substrate 101 than the touch line unit TP and the power line unit SP.

[0081] The data line DP may be electrically connected to a transistor of each pixel disposed in the display area DA to provide a data signal.

[0082] The data line unit DP may be formed as a single layer, a double layer, or a triple layer made of a conductive metal selected from the group consisting of aluminum (Al), copper (Cu), molybdenum (Mo), chromium (Cr), titanium (Ti), tungsten (W), molybdenum-tungsten (MoW), molybdenum-titanium (MoTi), and copper / molybdenum-titanium (Cu / MoTi). However, it is to be understood that the present disclosure is not limited thereto. The data line unit DP may be made of various metals or conductors.
