[0002] In recent years, with the development of technology, display products that are smaller, lighter and have better performance are being produced. Until now, cathode ray tube televisions (CRTs) have been widely used as display devices due to their many advantages in terms of performance and price, but display devices that solve the problems of CRTs in terms of miniaturization and portability and have advantages such as miniaturization, light weight and low power consumption, such as plasma display devices, liquid crystal display devices and organic light emitting display devices, are attracting attention.

[0003] The electronic device including the display device is implemented as a mobile terminal such as a smartphone, but has the disadvantage that a touch screen panel for a touch input function and a patch antenna for a communication function must be separately provided.

[0031] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the drawings.

[0032] FIG. 1 is a block diagram illustrating a display device according to an embodiment of the present invention.

[0033] As shown in FIG. 1, the display device includes a display panel (DP), a scan driver (SCAN), a data driver (DATA), an emission control driver (EM), a control unit (CON), a touch antenna array (TA), a touch driver (TSP), and an antenna driver (RF).

[0034] The display panel (DP) includes a number of pixels for displaying an image. For example, the display panel (DP) includes n*m pixels (where n and m are integers greater than 1) located at each intersection of a scan line extending in a first direction (D1) and a data line extending in a second direction (D2) perpendicular to the first direction (D1). The pixel structure may be any of a variety of known structures, and detailed description thereof will be omitted.

[0035] The scan driver (SCAN) sequentially provides scan signals to the pixels via the scan lines based on a control signal received from the controller (CON).

[0036] The data driver (DATA) provides data signals to the pixels via the data lines based on a control signal received from the controller (CON).

[0037] The light emission control driver (EM) sequentially provides light emission control signals to the pixels via light emission control lines based on a control signal received from the controller (CON).

[0038] The control unit (CON) controls the scan driver (SCAN), the data driver (DATA), and the emission control driver (EM). The control unit (CON) generates the control signals to control the scan driver (SCAN), the data driver (DATA), and the emission control driver (EM).

[0039] The display device further includes a power supply unit (not shown) that supplies a first power supply voltage (ELVDD), a second power supply voltage (ELVSS), and an initialization voltage (VINT) to the display panel (DP).

[0040] The touch antenna array (TA) includes a touch electrode for touch input function and an antenna electrode for communication function, and further includes a touch wiring, a ground wiring, a power supply line and a shielding electrode.

[0041] The touch wiring is electrically connected to the touch electrode. The ground wiring is applied with a ground voltage or a constant voltage (SV). In one embodiment, the ground voltage or the constant voltage (SV) is the same as any one of the first power supply voltage (ELVDD), the second power supply voltage (ELVSS), and the initialization voltage (VINT).

[0042] The power supply line is electrically connected to the antenna electrode. The shielding electrode is electrically connected to the ground line and is disposed between the touch line and the power supply line. A detailed description of the touch antenna array (TA) will be provided later with reference to FIGS. 2 and 3.

[0043] The touch driver (TSP) transmits an electrical signal to the touch electrode or receives an electrical signal from the touch electrode to sense a user's touch.

[0044] The antenna driver (RF) transmits an electrical signal to the antenna electrode or receives an electrical signal from the antenna electrode to perform a function of transmitting and receiving communication.

[0045] Specifically, the antenna driver (RF) includes a radio frequency integrated circuit (RFIC) that supplies power to the antenna electrode. The RFIC includes a high power amplifier (HPA) and a low noise amplifier (LNA). Here, a transmission signal from the high power amplifier (HPA) is radiated through the antenna electrode, and a reception signal received through the antenna electrode is amplified by the low noise amplifier (LNA).

[0046] FIG. 2 is a plan view showing the touch antenna array (TA) of FIG.

[0047] 1 to 3, the touch antenna array (TA) of the display device includes a plurality of antenna electrodes 210 arranged in a display area (AA), and a touch electrode (TE) including a plurality of first touch electrodes (TE1) and a plurality of second touch electrodes (TE2). The touch antenna array (TA) includes a touch driver (TSP) for driving the touch electrode (TE) and an antenna driver (RF) for driving the antenna electrode 210, which are arranged in a non-display area (NAA). The touch antenna array (TA) further includes a power supply line 212, touch wiring including a first touch wiring (RXL) and a second touch wiring (TXL), a ground wiring, and a shielding electrode electrically connected to the ground wiring.

[0048] The display device includes the display area (AA) in which an image is displayed, and the non-display area (NAA) adjacent to the display area (AA) on a plane formed by a first direction (D1) and a second direction (D2) perpendicular to the first direction (D1). The display area (AA) is an area in which the pixels of the display panel (DP) are arranged to display an image and where a user can input by touch, and the non-display area (NAA) is an area in which an image is not displayed, and is either shielded by a light shielding part (not shown) or disposed on the back surface of the display area (AA) as in the embodiment of FIG. 18 described later.

[0049] The touch electrode (TE) includes the plurality of first touch electrodes (TE1) and the plurality of second touch electrodes (TE2). The first touch electrodes (TE1) extend along the first direction (D1) and are arranged in the second direction (D2). That is, the first touch electrodes (TE1) in the first direction (D1) are electrically connected to each other. The first touch electrodes (TE1) are electrically connected to the first touch wiring (RXL). The touch wiring is electrically connected to the touch driver (TSP).

[0050] The second touch electrodes (TE2) extend along the second direction (D2) and are arranged in the first direction (D1). That is, the second touch electrodes (TE2) in the second direction (D2) are electrically connected to each other. The second touch electrodes (TE2) are electrically connected to the second touch wiring (TXL).

[0051] Each island pattern constituting the first and second touch electrodes (TE1, TE2) may have a rectangular or regular polygonal shape (particularly a square, a regular pentagon, or a regular hexagon) or various other shapes, and at least two to four main sides are arranged parallel to or inclined with respect to a first direction (D1) and a second direction (D2) perpendicular to the first direction (D1).

[0052] The antenna electrode 210 is disposed adjacent to the non-display area (NAA) in the display area (AA). The antenna electrode 210 is disposed apart from the touch electrode (TE) on a plane so as not to overlap with the touch electrode (TE). The antenna electrode 210 is electrically connected to the power supply line 212. The power supply line 212 is electrically connected to the antenna driver (RF).

[0053] Each island pattern (radiation pattern) constituting the antenna electrode 210 may have a rectangular or regular polygonal shape (particularly a square, a regular pentagon, or a regular hexagon) or other various shapes, similar to the touch electrodes (TE1, TE2), and at least two to four main sides are arranged parallel to or inclined with respect to the first direction (D1) and the second direction (D2). The shape and size of each radiation pattern may be appropriately designed depending on the frequency range used by the antenna electrode.

[0054] For example, the antenna electrode 210 may have a repeating pattern in which the same island patterns are repeatedly arranged in one direction, and the first and second touch electrodes may have the same repeating pattern as the antenna electrode 210, which is composed of island patterns having the same shape and size as the island pattern of the antenna electrode 210. Each island pattern of the antenna electrode 210 may be a metal or other conductor in the shape of a lattice or mesh.

[0055] That is, most of the repeating patterns of a grid or mesh shape arranged in the display area (AA) constitute the touch electrode, and a part of the pattern shape adjacent to the non-display area (NAA) constitutes the antenna electrode 210.

[0056] The antenna electrode 210 is made of a conductive layer disposed between insulating layers. The conductive layer may include silver (Ag), gold (Au), copper (Cu), aluminum (Al), platinum (Pt), palladium (Pd), chromium (Cr), titanium (Ti), tungsten (W), niobium (Nb), tantalum (Ta), vanadium (V), iron (Fe), manganese (Mn), cobalt (Co), nickel (Ni), zinc (Zn), tin (Sn), or an alloy thereof. These may be used alone or in combination of two or more. The conductive layer may be formed using a transparent metal oxide such as indium tin oxide (ITO), indium zinc oxide (IZO), indium zinc tin oxide (ITZO), or zinc oxide (ZnOx).

[0057] When the antenna electrode is made of silver (Ag), it has the advantage that it has excellent transparency when made into a lattice or mesh shape, and also has excellent electrical properties such as the radiation characteristics of the antenna. In particular, silver (Ag) can be realized with the narrowest line width, and the lattice (or mesh) interval can be realized with the finest precision. Therefore, in the millimeter wave band of 28 GHz or 39 GHz frequency band, silver has the advantage that it is possible to design an antenna electrode and a feeder line with a narrow line width.

[0058] Meanwhile, the antenna electrode 210 and the power feed line 212 may be implemented in the form of a metal mesh. Here, the antenna electrode and the power feed line may be implemented in the form of an electrically connected metal mesh, and a dielectric region where the antenna electrode and the power feed line are not present may be implemented in the form of a metal mesh being removed. In another embodiment, the metal mesh is also disposed adjacent to the antenna electrode and the power feed line in the dielectric region to an extent that does not electrically affect the antenna electrode and the power feed line. The metal mesh disposed in such a dielectric region is not a region where a signal is transmitted or radiated, but it can improve the visibility of the display by being uniformly disposed over the entire region of the display.

[0059] Meanwhile, the shapes and arrangements of the touch electrode and the antenna electrode 210 may be variously changed as required.

[0060] The touch driver (TSP) is disposed in the non-display area (NAA). The touch driver (TSP) is configured as an integrated circuit directly mounted on the touch antenna array (TA), or a pad electrode is formed on the touch antenna array (TA) and the touch driver (TSP) is connected to another drive substrate by the pad electrode.

[0061] The antenna driving unit (RF) is disposed in the non-display area (NAA). The antenna driving unit (RF) is configured as an integrated circuit directly mounted on the touch antenna array (TA), or has a configuration in which a pad electrode is formed on the touch antenna array (TA) and the antenna driving unit (RF) is connected to another driving substrate by the pad electrode.

[0062] The touch wiring, the ground wiring, the power supply line 212, and the shielding electrode are disposed in the non-display area (NAA).

[0063] Meanwhile, in the illustrated example, it is described that one power feed line is connected to one antenna electrode, but two or more power feed lines may be connected to one antenna electrode to perform dual power feeding.

In the example shown in FIG. 13, the pattern is a square like the case of FIG. 1, but each side is inclined at about 45 degrees to the first and second directions (D1, D2), so it is called a "diamond shape". In addition, in the example shown in Figure 13, in each island-shaped unit pattern forming the first and second touch electrodes (TE), the lattice openings or meshes are all located corresponding to openings (OP) that approximately coincide with the light-emitting area, and in particular, the openings (OP) that approximately coincide with the light-emitting area are located at the center of each lattice opening or mesh.

The shielding electrode 122 is formed in the non-display area (NAA) to extend in the first direction (D1) along the power supply line 212 and overlap the power supply line 212.

Also, the interlayer insulating layer 320 is disposed on the gate insulating layer 310 to cover the gate pattern, with a uniform thickness, according to the profile of the gate pattern. The interlayer insulating layer 320 includes a silicon compound, a metal oxide, etc. Also, the interlayer insulating layer 320 has a multi-layer structure including a plurality of insulating layers. For example, the insulating layers may include different thicknesses or materials.

[0170] As shown in Figures 17 and 18, the display device includes a display panel (DP), a touch antenna array (TA), and a cover window (CW).

[0171] The display device includes a display area (AA) in which an image is displayed, and a non-display area (NAA) adjacent to the display area.

[0172] The display area (AA) includes a main display area (MA) and a first edge display area (EA1) and a second edge display area (EA2) adjacent to the main display area (MA). For example, the main display area (MA) has a rectangular shape extending along a first direction (D1) and a second direction (D2) perpendicular to the first direction (D1), and each of the first edge display area (EA1) and the second edge display area (EA2) extends along the second direction (D2) and is connected to the left and right sides of the main display area (MA) in the first direction (D1). The first edge display area (EA1) and the second edge display area (EA2) are curved in a third direction (D3) perpendicular to the first direction (D1) and the second direction (D2) to form a curved surface.

[0173] The display panel (DP) is a flexible display panel, for example a flexible organic light-emitting display panel.

[0174] The touch antenna array (TA) is disposed on the display panel (DP) and includes a touch electrode and an antenna electrode in the display area (AA). The antenna electrode is disposed in the first or second edge display area (EA1, EA2).

[0175] The touch antenna array (TA) includes ground lines, touch lines, shielding electrodes, and power lines in the non-display area (NAA).

[0176] The antenna driving unit (RF) is disposed in the non-display area (NAA). The antenna driving unit (RF) is configured as an integrated circuit directly mounted on the touch antenna array (TA), or a pad electrode is formed on the touch antenna array (TA) and the antenna driving unit (RF) is connected to another driving substrate by the pad electrode.

[0177] The cover window (CW) is attached on the touch antenna array (TA) using an adhesive layer (not shown). The cover window (CW) has curved edges to correspond to the curved surfaces of the first and second edge display areas (EA1, EA2). The cover window (CW) can form a part of the outer surface of an electronic device (e.g., a smartphone) including the display device.

[0178] In the first or second edge display area (EA1, EA2), a portion where the non-display area (NAA) and the display area (AA) are connected is folded so that the non-display area (NAA) is located behind the display area (AA). That is, edges of the display panel (DP) and the touch antenna array (TA) can be folded and located behind the display surface. Thus, the antenna driver (RF) is located behind the display surface of the display panel (DP).

[0179] FIG. 19 is a cross-sectional view of a first edge area (EA1) of a display device according to an embodiment of the present invention.

[0180] As shown in Fig. 19, the display device is substantially the same as the display device in Fig. 18, except that the touch antenna array (TA) is formed longer than the display panel (DP) and the edge of the touch antenna array (TA) is folded. Therefore, repeated description is omitted.

[0181] The display device includes a display panel (DP), a touch antenna array (TA), and a cover window (CW).

[0182] The edge of the touch antenna array (TA) where the antenna driver (RF) is disposed can be folded and positioned behind the display surface. Thus, the antenna driver (RF) is positioned behind the display surface of the display panel (DP). Here, the touch antenna array (TA) can include a base film (such as FIG. 9) that is larger than the substrate (300 in FIG. 15) of the display panel (DP).

[0183] FIG. 20 is a block diagram showing an electronic device according to an embodiment of the present invention.

[0184] As shown in FIG. 20, the electronic device 500 includes a processor 510, a memory device 520, a storage device 530, an input / output device 540, a power supply 550, and a display device 560. Here, the display device 560 corresponds to the display device of FIG. 1. The electronic device 500 further includes a plurality of ports for communicating with a video card, a sound card, a memory card, a USB device, or other systems. In one embodiment, the electronic device 500 may be embodied in a smartphone. However, this is merely an example, and the electronic device 500 is not limited thereto. For example, the electronic device 500 may be embodied in a television, a video phone, a smart pad, a smart watch, a tablet PC, a vehicle navigation system, a computer monitor, a notebook computer, a head mounted display (HMD), or the like.

[0185] The processor 510 performs a particular calculation or task. In an embodiment, the processor 510 is a microprocessor, a central processing unit (CPU), an application processor (AP), or the like. The processor 510 is coupled to other components via an address bus, a control bus, a data bus, or the like. In an embodiment, the processor 510 is also coupled to an expansion bus, such as a Peripheral Component Interconnect (PCI) bus. The memory device 520 may store data necessary for the operation of the electronic device 500. For example, the memory device 520 may include non-volatile memory devices, such as EPROM devices, EEPROM devices, flash memory devices, PRAM devices, ReRAM devices, Nano Floating Gate Memory (NFGM) devices, Polymer Random Access Memory (PoRAM) devices, Magnetic Random Access Memory (MRAM), Ferroelectric Random Access Memory (FeRAM) devices, and / or volatile memory devices, such as DRAM devices, SRAM devices, mobile DRAM devices, and the like. The storage device 530 includes a solid state drive (SSD), a hard disk drive (HDD), a CD-ROM, etc. The input / output device 540 includes input means such as a keyboard, a keypad, a touchpad, a touch screen, a mouse, etc., and output means such as a speaker, a printer, etc. The power supply 550 provides power required for the operation of the electronic device 500.

[0186] The display device 560 is connected to other components via the bus or other communication link. In an embodiment, the display device 560 is included in the input / output device 540. As described above, the display device 560 includes a display panel on which an image is displayed, and a touch antenna array disposed on the display panel. The touch antenna array includes a touch electrode and an antenna electrode, and performs a touch function and an antenna function. Here, a shielding electrode to which a ground voltage or a constant voltage is applied is disposed between a touch wiring electrically connected to the touch electrode and a power supply line electrically connected to the antenna electrode, so that a problem of signal distortion due to coupling capacitance between the touch wiring and the power supply line driven at different frequencies and voltages can be prevented.

[0187] However, since this has been described above, a duplicated explanation will be omitted. [Industrial Applicability]

[0188] The present invention can be applied to an organic light emitting display device and various electronic devices including the same, such as mobile phones, smartphones, video phones, smart pads, smart watches, tablet PCs, vehicle navigation systems, televisions, computer monitors, notebook computers, head mounted displays, etc.

[0189] Although the present invention has been described above with reference to exemplary embodiments, those skilled in the art will appreciate that various modifications and variations of the present invention may be made without departing from the spirit and scope of the present invention as set forth in the following claims.

[0190] According to one preferred embodiment, the following is true:

[0191] The background and issues of this case are as follows (i) to (vi).

[0192] (i) Mobile terminals such as smartphones, smart watches, and tablet PCs are provided with a display panel covering almost the entire front side. A touch screen is provided on the front side of the display panel by attaching a touch panel or the like.

[0193] The capacitive coupling method is the mainstream for this type of touch screen, and island-shaped unit patterns that make up the touch electrodes are arranged to almost completely fill the entire image display surface. These island-shaped unit patterns are connected by bridge sections in the X direction (left-right direction) to form the X-direction touch electrodes, and are connected by bridge sections in the Y direction (vertical direction) to form the Y-direction touch electrodes.

[0194] Island-shaped unit patterns constituting the X-direction touch electrodes and island-shaped unit patterns constituting the Y-direction touch electrodes are arranged in a staggered manner, and bridge portions of the X-direction touch electrodes and bridge portions of the Y-direction touch electrodes intersect with an insulating film sandwiched therebetween.

[0195] (ii) A metal casing is usually attached to the rear side of a mobile terminal. In order to make the mobile terminal thinner, it has been considered to place the antenna of the mobile terminal on the front side, instead of on the rear side covered by the metal casing (Patent Documents 1 to 4). For this purpose, it has been proposed to place an antenna electrode (conductive pattern forming an antenna) in the non-display area on the periphery of the display panel (Patent Documents 1 and 4), or to place an antenna electrode in the unit pattern array area of ​​the touch electrode (Patent Documents 2 to 3).

[0196] (iii) In recent years, in high-end mobile terminals and the like, the non-display area around the periphery of the display panel has been extremely narrowed or eliminated, leading to a trend toward bezel-less displays. To achieve this, for example, the non-display area around the periphery of the display panel is bent toward the rear side or folded back on the rear side. For this purpose, organic light-emitting display devices, which can be easily made into flexible display panels, are used.

[0197] (iv) However, if the antenna electrode is arranged in the display area by overlapping the touch electrode and the antenna electrode and then placing a thick insulating film between them, the sensitivity of the touch electrode may be reduced, and this is not preferable from the viewpoint of making mobile terminals thinner, lighter, and less expensive.

[0198] (v) On the other hand, in order to maintain high antenna sensitivity, it is preferable that the antenna electrode has a length equivalent to, for example, one of the long sides of the display panel and extends along the edge of the display panel.

[0199] (vi) When the length of the antenna electrode is increased as in (v) above, it is desirable to arrange a large number of power supply lines connecting the antenna electrode and the driving circuit in the peripheral non-display area and distribute them throughout the entire area to which the antenna electrode extends. However, since a large number of touch wirings connecting the touch electrodes and the driving circuits are arranged in the peripheral non-display area, a large number of power supply lines and a large number of touch wirings intersect at a large number of points, which causes undesirable coupling capacitance at these intersections.

[0200] According to a preferred embodiment, particularly based on the discovery of the above problems (iv) to (vi), the present invention is as follows: A1 to A4. Also, the present invention may be at least one of A5 to A8.

[0201] A1 Along the edge of the display area (AA in FIG. 2), for example, one or two rows of the island pattern of the touch electrode (TE) are omitted, and instead, an island pattern for the antenna electrode (210) is arranged. That is, in a straight line or L-shape, for example, over a range longer than the length of one short side of the display area (AA) and shorter than the combined length of one long side and one short side, particularly over a range roughly corresponding to the length of the long side of the display area (AA), the island pattern of the touch electrode (TE) is replaced with an island pattern of the antenna electrode (210), for example only in the outermost row. Therefore, the touch electrode (TE) and the antenna electrode (210) do not overlap except where the bridge portions intersect. In particular, the island pattern of the touch electrode (TE) and the island pattern of the antenna electrode (210) are isolated from each other in a plan view.

[0202] A2 Each island pattern constituting the antenna electrode can be made exactly the same as each island pattern constituting the touch electrode (210) in terms of shape, dimensions, openings, etc. The series of island patterns constituting the antenna electrode can be connected to each other by a bridge portion as appropriate. In addition to this, or instead of this, multiple power supply lines from a driving circuit for the antenna can be extended and connected to each of the series of island patterns.

[0203] A3 In the non-display area (NAA in FIG. 2) on the periphery of the display panel, at the point where the power supply line (212) for the antenna and the touch wiring (114; RXL) intersect, a shielding electrode ("122" in FIGS. 3 to 10 and 13 to 14; "202" in FIGS. 11 to 12) is arranged at a point sandwiched between them from above and below (in the thickness direction of the display panel).

[0204] A4: It is not preferable for the shielding electrode (122; 202) to be an electrically floating pattern, so it is connected to a wiring that supplies a constant voltage. For example, it is connected to the ground wiring (212) from the display panel with a touch screen. Alternatively, when the display panel is an organic light emitting display device, the high level power supply voltage line, the low level power supply voltage line, the initialization voltage line, and the like may be connected.

[0205] The shielding electrode (122; 202) overlapping the power feed line (212) for the A5 antenna is provided as a linear pattern extending along the power feed line (212) (FIG. 13). The width of the shielding electrode (122; 202) can be wider than the width of the power feed line (212) by an appropriate margin, for example, 1.1 to 5 times or 1.5 to 3 times the width of the power feed line (212).

[0206] A6 When the display panel is an organic light-emitting display device, in particular, the image display surface can be curved and extend to the edge surface (end surface) of the mobile terminal. In this case, the antenna electrode (210) is disposed in the region of this edge surface (FIGS. 17 to 18). Additionally, the non-display area (NAA) around the periphery of the display panel is folded back to the rear side of the display panel (FIG. 18).

[0207] A7 The antenna electrode 210 and the power supply line 212 may be formed on a separate elongated film and attached to the edge of the display panel with a touch screen. In particular, in the case of A6 above, the antenna electrode 210 may be located at the outer edge of the edge surface.

[0208] A8 Each island pattern of the antenna electrode (210) and the touch electrode (210) can be formed of a metal lattice or mesh. In this case, an opening for each pixel of the display panel can be arranged in the opening or cutout of each island pattern, and in the case of an organic light emitting display device, the light emitting area for each pixel can be located in the center of the opening or cutout.
