Technical Field

[0001] This invention relates to a display device. Background Technology

[0002] With the development of the information society, the demand for display devices for displaying images has increased in many forms. For example, display devices are used in a variety of electronic devices such as smartphones, digital cameras, laptops, navigation devices, and smart TVs.

[0003] Display devices may include antennas for transmitting and receiving radio electromagnetic waves for wireless communication. For example, a display device may include antennas for fourth-generation (4G) mobile communication and fifth-generation (5G) mobile communication, such as Long Term Evolution (LTE). Therefore, the frequency bands of the radio electromagnetic waves transmitted and received vary depending on the communication technology, and the shape or length of the antenna can differ according to the frequency band of the radio electromagnetic waves. Thus, display devices require antennas tailored to the frequency bands of the radio electromagnetic waves. Summary of the Invention

[0005] The technical problems of this invention are not limited to those mentioned above, and other technical problems not mentioned can be clearly understood by those skilled in the art through the following description.

[0006] A display device according to one embodiment for solving the above-mentioned technical problems includes: a substrate; a display layer disposed on the substrate and including a light-emitting element; a sensor electrode layer disposed on the display layer and including sensor electrodes and sensor wiring connected to the sensor electrodes; and a circuit board including sensor circuit wiring electrically connected to the sensor wiring and wireless signal wiring forming a coupling capacitor with the sensor circuit wiring.

[0008] A display device according to another embodiment for solving the above-mentioned technical problems includes: sensor electrodes disposed on a substrate; sensor wiring electrically connected to the sensor electrodes; wireless signal wiring forming a coupling capacitor with the sensor wiring; and an antenna driving circuit electrically connected to the wireless signal wiring. The antenna driving circuit receives a coupling signal of a wireless received signal received by the sensor electrodes through the wireless signal wiring, selects a portion of the sensor electrodes as antenna electrodes according to the coupling signal, and outputs a wireless transmitted signal to the antenna electrodes.

[0009] Specific details of other embodiments are included in the detailed description and accompanying drawings.

[0010] The display device according to an embodiment includes a wireless signal connection section having a coupling capacitor that provides touch sensing signals and wireless reception signals from sensor electrodes to a touch driving circuit and an antenna driving circuit. This allows not only the sensor electrodes to sense a user's touch, but also to perform mobile communication. In other words, the sensor electrodes used for sensing touch can be used as an antenna.

[0011] According to the display device of the embodiment, the antenna driving circuit can use a first antenna electrode to receive a first wireless reception signal and transmit a first wireless transmission signal. Furthermore, the antenna driving circuit can use a second antenna electrode to receive a second wireless reception signal and transmit a second wireless transmission signal. That is, a portion of the sensor electrodes used for sensing touch can be used as a first antenna, and another portion can be used as a second antenna for transmitting and receiving electromagnetic waves at a different frequency than the first antenna.

[0068] References and Appendix Figure 1 The advantages and features of the invention, as well as the methods for achieving them, will become clear from the detailed embodiments described below. However, the invention can take many different forms and is not limited to the embodiments disclosed below. These embodiments are provided only to complete the disclosure of the invention and to fully inform those skilled in the art of the invention of its scope. The invention is defined only by the scope of the claims.

[0069] The reference to elements or layers being "on" other elements or layers includes situations where they are immediately above or adjacent to other elements, or where other layers or elements are sandwiched in between. Throughout this specification, the same reference numerals refer to the same constituent elements. The shapes, sizes, proportions, angles, quantities, etc., disclosed in the drawings used to illustrate embodiments are exemplary, and therefore the invention is not limited to the illustrated matters.

[0070] Although terms such as "first," "second," etc., are used to describe various constituent elements, these constituent elements are clearly not limited to these terms. These terms are only used to distinguish one constituent element from another. Therefore, the "first constituent element" mentioned below can obviously also be a "second constituent element" within the technical concept of this invention.

[0071] The various features of the multiple embodiments of the present invention can be partially or completely combined or integrated with each other, and can be linked and driven in various ways in terms of technology. Each embodiment can be implemented independently of each other, or can be implemented together in a related relationship.

[0072] The specific embodiments will now be described with reference to the accompanying drawings.

[0073] Figure 1 This is a perspective view showing a display device according to an embodiment. Figure 2 This is an exploded perspective view showing a display device according to an embodiment.

[0074] For ease of explanation, Figure 1 and Figure 2 The illustration shows a scenario where the display device 10 according to one embodiment is used in a smartphone, but it is not limited thereto. The display device 10 according to one embodiment can be a portable electronic device such as a mobile phone, smartphone, tablet personal computer, mobile communication terminal, e-notebook, e-reader, portable multimedia player (PMP), navigator, ultra-portable mobile PC (UMPC), etc. Alternatively, the display device 10 according to one embodiment can be a display unit of a television, laptop computer, monitor, billboard, or Internet of Things (IoT). Alternatively, the display device 10 according to one embodiment can be a wearable device such as a smartwatch, watch phone, glasses display, or head-mounted display (HMD). Alternatively, the display device 10 according to one embodiment may be a car dashboard, a car center fascia, a center information display (CID) arranged on the car's control panel, an interior mirror display that replaces the vehicle's side mirrors, or a display arranged on the back of the front seats as a rear seat entertainment device for the vehicle.

[0075] Reference Figure 1 and Figure 2 According to one embodiment, the display device 10 includes a cover window 100, a display panel 300, a display circuit board 310, a display driving circuit 320, a touch driving circuit 330, an antenna driving circuit 340, a bracket 600, a main circuit board 700, a battery 790, and a lower cover 900.

[0076] In this specification, the first direction (X-axis direction) refers to the direction of the short side of the display device 10, such as the horizontal direction of the display device 10. The second direction (Y-axis direction) refers to the direction of the long side of the display device 10, such as the vertical direction of the display device 10. The third direction (Z-axis direction) can be the thickness direction of the display device 10.

[0077] The display device 10 can be configured as a rectangular planar shape. For example, as Figure 1 As shown, the display device 10 can be a rectangular planar shape having a short side in a first direction (X-axis direction) and a long side in a second direction (Y-axis direction). The corner where the short side in the first direction (X-axis direction) and the long side in the second direction (Y-axis direction) meet can be formed as an arc with a predetermined curvature or as a right angle. The planar shape of the display device 10 is not limited to a rectangle, and can be formed as other polygons, circles, or ellipses.

[0078] The display device 10 may include a first region DRA1 and a second region DRA2 extending from the left and right sides of the first region DRA1. The first region DRA1 may be formed flat or curved. The second region DRA2 may be formed flat or curved. When both the first region DRA1 and the second region DRA2 are curved, the curvature of the first region DRA1 and the curvature of the second region DRA2 may be different. When the first region DRA1 is curved, it may have a constant curvature or a varying curvature. When the second region DRA2 is curved, it may have a constant curvature or a varying curvature. When both the first region DRA1 and the second region DRA2 are flat, the angle formed by the first region DRA1 and the second region DRA2 may be an obtuse angle.

[0079] exist Figure 1 The example illustrates the scenario where the second region DRA2 extends from the left and right sides of the first region DRA1, but it is not limited to this. That is, the second region DRA2 may extend only from one of the left or right sides of the first region DRA1. Alternatively, the second region DRA2 may extend not only from the left or right sides of the first region DRA1, but also from at least one of the upper or lower sides. Alternatively, the second region DRA2 may be omitted, and the display device 10 may include only the first region DRA1.

[0080] The cover window 100 can be arranged on the upper part of the display panel 300 in a manner that covers the upper surface of the display panel 300. The cover window 100 can serve to protect the upper surface of the display panel 300.

[0081] The cover window 100 may be made of a transparent material and may include glass or plastic. For example, the cover window 100 may include ultra-thin glass (UTG) with a thickness of less than 0.1 mm. The cover window 100 may include a transparent polyimide film.

[0082] The covering window 100 may include a light-transmitting portion DA100 and a light-blocking portion NDA100. The light-blocking portion NDA100 may include a pattern layer on which a predetermined pattern is formed.

[0083] The display panel 300 can be arranged at the bottom of the overlay window 100. The display panel 300 can be arranged in a first area DRA1 and a second area DRA2. Users can view the image on the display panel 300 in the first area DRA1 and the second area DRA2.

[0084] Display panel 300 can be a light-emitting display panel that includes a light-emitting element. For example, display panel 300 can be an organic light-emitting display panel that uses an organic light-emitting diode (OLED) including an organic light-emitting layer, an ultra-small light-emitting diode (LED) display panel that uses a micro LED, a quantum dot light-emitting display panel that uses a quantum dot light-emitting element including a quantum dot light-emitting layer, or an inorganic light-emitting display panel that uses an inorganic light-emitting element that includes an inorganic semiconductor.

[0085] The display panel 300 can be a rigid display panel that is rigid and not easily bent, or a flexible display panel that is flexible and can be easily bent, folded, or rolled. For example, the display panel 300 can be a foldable display panel that can be folded and unfolded, a curved display panel with a curved display surface, a bent display panel with a curved area outside the display surface, a rollable display panel that can be rolled and unfolded, and a stretchable display panel that can be extended.

[0086] Alternatively, the display panel 300 can be a transparent display panel that allows objects or backgrounds arranged below the display panel 300 to be seen from the top of the display panel 300. Alternatively, the display panel 300 can be a reflective display panel that reflects objects or backgrounds above the display panel 300.

[0087] like Figure 2As shown, the display panel 300 may include a main region MA and a sub-region SBA protruding from one side of the main region MA.

[0088] The main area MA may include a display area DA for displaying the image and a non-display area NDA surrounding the display area DA. The display area DA may occupy most of the main area MA. The display area DA may be located in the center of the main area MA. The non-display area NDA may be the outer area of ​​the display area DA. The non-display area NDA may be defined as the edge area of ​​the display panel 300.

[0089] The subregion SBA can protrude from one side of the main region MA along the second direction (Y-axis direction). For example... Figure 2 As shown, the length of the sub-region SBA in the first direction (X-axis direction) can be less than the length of the main region MA in the first direction (X-axis direction), and the length of the sub-region SBA in the second direction (Y-axis direction) can be less than the length of the main region MA in the second direction (Y-axis direction), but it is not limited to these. The sub-region SBA can be curved and can be arranged on the lower surface of the display panel 300 as shown in Figure 5. The sub-region SBA can overlap with the main region MA in the third direction (Z-axis direction).

[0090] A display circuit board 310 may be attached to a sub-region SBA of the display panel 300. The display circuit board 310 may be attached to the display pad of the sub-region SBA of the display panel 300 using a low-resistance, high-reliability material such as anisotropic conductive film or self-assembly anisotropic conductive paste (SAP). The display circuit board 310 may be a flexible printed circuit board (FPCB), a rigid printed circuit board (PCB), or a composite printed circuit board including both rigid and flexible printed circuit boards. The display circuit board 310 may have characteristics that minimize path loss of transmitted and received wireless signals.

[0091] The display driving circuit 320 can be arranged on a sub-region SBA of the display panel 300. The display driving circuit 320 can receive control signals and power supply voltage, and generate and output signals and voltages for driving the display panel 300. The display driving circuit 320 can be formed as an integrated circuit (IC).

[0092] Touch driving circuit 330 and antenna driving circuit 340 can be arranged on display circuit board 310. Each of touch driving circuit 330 and antenna driving circuit 340 can be formed as an integrated circuit. Alternatively, touch driving circuit 330 and antenna driving circuit 340 can be integrated into a single integrated circuit. Each of touch driving circuit 330 and antenna driving circuit 340 can be attached to display circuit board 310. Alternatively, antenna driving circuit 340 can be arranged on main circuit board 700 instead of display circuit board 310.

[0093] The touch driving circuit 330 is electrically connected to the sensor electrodes of the sensor electrode layer of the display panel 300 via the display circuit board 310. Therefore, it can output touch driving signals to each of the sensor electrodes and sense the voltage charging in the self-capacitance of each sensor electrode. The touch driving circuit 330 generates touch data based on the changes in the sensed electrical signals at each sensor electrode and transmits it to the main processor 710. The main processor 710 calculates the touch coordinates of the touch occurrence by analyzing the touch data. Touch can include contact touch and proximity touch. Contact touch refers to a person's finger or pen directly contacting the covering window 100 arranged on the sensor electrode layer. Proximity touch refers to a person's finger or pen being close to but spaced apart from the covering window 100, similar to hovering.

[0094] The antenna driving circuit 340 can be electrically connected to the sensor electrodes of the sensor electrode layer of the display panel 300 via the wireless signal connection unit RFC, thus enabling it to transmit wireless signals to each of the sensor electrodes and receive wireless signals from each of the sensor electrodes. The wireless signal connection unit RFC can be as follows: Figure 6 As shown, it is arranged on the display circuit board 310, or as... Figure 30 It is arranged on the display panel 300 as shown.

[0095] The antenna driving circuit 340 can change the phase of the wireless received signal and amplify its amplitude before transmitting it to the mobile communication module 720 of the main circuit board 700. Furthermore, the antenna driving circuit 340 can change the phase of the wireless transmitted signal transmitted from the mobile communication module 720 of the main circuit board 700 and amplify its amplitude before transmitting it to each of the sensor electrodes. Alternatively, the antenna driving circuit 340 and the mobile communication module 720 of the main circuit board 700 can be integrated into each other.

[0096] A power supply unit for supplying driving voltage to the display pixels of the display panel 300 and the display driving circuit 320 can be additionally arranged on the display circuit board 310. Alternatively, the power supply unit can be integrated with the display driving circuit 320, in which case the display driving circuit 320 and the power supply unit can be formed as an integrated circuit.

[0097] A support bracket 600 for supporting the display panel 300 may be arranged at the lower part of the display panel 300. The support bracket 600 may be made of plastic, metal, or both plastic and metal. The support bracket 600 may have a first camera hole CMH1 for inserting the camera device 731, a battery hole BH for arranging the battery 790, and a cable hole CAH for the cable 314 connected to the display circuit board 310 to pass through.

[0098] The main circuit board 700 and the battery 790 can be arranged at the lower part of the bracket 600. The main circuit board 700 can be a printed circuit board or a flexible printed circuit board.

[0099] The main circuit board 700 may include a main processor 710, a mobile communication module 720, a camera device 731, an accelerometer sensor 740, a gyroscope sensor 750, a proximity sensor 760, and a main connector 711. The main processor 710 may be formed as an integrated circuit. The camera device 731 may be arranged on both the upper and lower surfaces of the main circuit board 700, and each of the main processor 710, mobile communication module 720, accelerometer sensor 740, gyroscope sensor 750, proximity sensor 760, and main connector 711 may be arranged on one of the upper and lower surfaces of the main circuit board 700.

[0100] The main processor 710 can control all functions of the display device 10. For example, the main processor 710 can output digital video data to the display driver circuit 320 via the display circuit board 310, causing the display panel 300 to display an image. Furthermore, the main processor 710 receives touch data from the touch driver circuit 330. The main processor 710 can determine whether an object is touching the device based on the touch data and execute operations corresponding to direct or near-touch. For example, the main processor 710 can calculate the touch coordinates of an object by analyzing the touch data, and then run the application indicated by the icon touched by the object or execute an operation. Furthermore, the main processor 710 can determine the degree of tilt and rotation direction of the display device 10 based on acceleration data from the accelerometer 740 and angular velocity data from the gyroscope sensor 750, and can determine whether an object such as a human finger is near the display panel 300 via the proximity sensor 760. Finally, the main processor 710 can output touch coordinate data, including touch coordinate information, to the antenna driver circuit 340. Furthermore, the main processor 710 can output acceleration data from the accelerometer 740 and angular velocity data from the gyroscope sensor 750 to the antenna drive circuit 340. The main processor 710 can be an application processor, a central processing unit, or a system chip constructed using integrated circuits.

[0101] The mobile communication module 722 transmits and receives radio signals with at least one of a base station, an external terminal, and a server on a mobile communication network built according to technical standards or communication methods used for mobile communication (e.g., Global System for Mobile communication (GSM), Code Division Multi Access (CDMA), Code Division Multi Access 2000 (CDMA2000), Enhanced Voice-Data Optimized or Enhanced Voice-Data Only (EV-DO), Wideband CDMA (WCDMA), High Speed ​​Downlink Packet Access (HSDPA), High Speed ​​Uplink Packet Access (HSUPA), Long Term Evolution (LTE), Long Term Evolution-Advanced (LTE-A), 5G, etc.). The radio signals may include audio call signals, video call signals, or data in various formats depending on the transmission and reception of text / multimedia messages.

[0102] Camera device 731 processes still or moving image frames acquired by an image sensor in camera mode and outputs them to main processor 710. Camera device 731 may include at least one of a camera sensor (e.g., CCD, CMOS, etc.), a light sensor (or an image sensor), and a laser sensor.

[0103] Accelerometer 740 can sense acceleration in a first direction (X-axis), a second direction (Y-axis), and a third direction (Z-axis). Accelerometer 740 can output acceleration data, including acceleration information in the first direction (X-axis), the second direction (Y-axis), and the third direction (Z-axis), to main processor 710.

[0104] The gyroscope sensor 750 can sense angular velocities in a first direction (X-axis), a second direction (Y-axis), and a third direction (Z-axis). The gyroscope sensor 750 can output angular velocity data, including angular velocity information in the first direction (X-axis), the second direction (Y-axis), and the third direction (Z-axis), to the main processor 710.

[0105] The proximity sensor 760 is a sensor used to sense whether an object is close to the front of the display device 10. The proximity sensor 760 may include a light source that outputs light and a light receiver that receives light reflected by the object. The proximity sensor 760 can determine whether an object is close to the front of the display device 10 based on the amount of light reflected by the object. The proximity sensor 760 can generate proximity sensor data based on the presence of an object close to the front of the display device 10 and output it to the main processor 710.

[0106] The main processor 710 can be connected to a cable 314 that passes through the cable hole CAH of the bracket 600, thereby allowing the main circuit board 700 to be electrically connected to the display circuit board 310.

[0107] The lower cover 900 can be disposed below the main circuit board 700 and the battery 790. The lower cover 900 can be fastened to the bracket 600 for fixation. The lower cover 900 can form the lower surface appearance of the display device 10. The lower cover 900 can include plastic, metal, or both plastic and metal.

[0108] A second camera aperture CMH2 may be formed on the lower cover 900 to expose the lower surface of the camera device 731. The position of the camera device 731 and the positions of the corresponding first camera aperture CMH1 and second camera aperture CMH2 are not limited to... Figure 2 The example shown.

[0109] Figure 3 and Figure 4 This is a plan view showing a display panel according to one embodiment. Figure 3 A plan view of the display panel 300 is shown with the sub-region SBA unfolded without bending. Figure 4 A plan view of the display panel 300 is shown with the sub-region SBA bent toward the lower surface of the display panel 300.

[0110] Reference Figure 3 and Figure 4 The display panel 300 may include a main area MA and a sub-area SBA. The main area MA may include a display area DA in which display pixels are arranged and the image is displayed, and a non-display area NDA surrounding the display area DA and not displaying the image.

[0111] The subregion SBA can protrude from one side of the main region MA in a second direction (Y-axis direction). For example... Figure 3As shown, the length of the sub-region SBA in the first direction (X-axis direction) can be less than the length of the main region MA in the first direction (X-axis direction), and the length of the sub-region SBA in the second direction (Y-axis direction) can be less than the length of the main region MA in the second direction (Y-axis direction), but is not limited thereto. The sub-region SBA can be curved and can be arranged on the lower surface of the display panel 300. The sub-region SBA can overlap with the main region MA in a third direction (Z-axis direction), which is the thickness direction of the display panel 300.

[0112] A display circuit board 310 and a display driving circuit 320 may be arranged in the sub-region SBA. The display circuit board 310 may be arranged on a pad arranged on one side of the sub-region SBA. The display circuit board 310 may be attached to the pad of the sub-region SBA using an anisotropic conductive film.

[0113] In addition, Figure 3 The example illustrates that the display driving circuit 320 is arranged on the display panel 300, and the touch driving circuit 330 and antenna driving circuit 340 are arranged on the display circuit board 310; however, this is not a limitation. For example, the display driving circuit 320, touch driving circuit 330, and antenna driving circuit 340 can all be arranged on the display circuit board 310. Or, as... Figure 36 and Figure 37 As shown, the display driving circuit 320 can be arranged on the display panel 300, the touch driving circuit 330 can be arranged on the display circuit board 310, and the antenna driving circuit 340 can be arranged on the antenna circuit board 360. Alternatively, the display driving circuit 320 and the touch driving circuit 330 can be arranged on the display circuit board 310, and the antenna driving circuit 340 can be arranged on the antenna circuit board 360. Alternatively, the touch driving circuit 330 can be arranged on the display circuit board 310, and the display driving circuit 320 and the antenna driving circuit 340 can be arranged on the antenna circuit board 360.

[0114] Figure 5a It shows along Figure 4 A cross-sectional view of the overlay window and display panel according to one embodiment, taken along line A-A'. Figure 4 Same, Figure 5a A cross-sectional view of the display panel 300 is shown with the sub-region SBA bent and arranged on the lower surface of the display panel 300.

[0115] Reference Figure 5a The display panel 300 may include a substrate SUB, a display layer DISL, a sensor electrode layer SENL, a polarizing film PF, and a lower cover PB.

[0116] Substrate Substrates (SUBs) can be made of insulating materials such as glass, quartz, and polymer resin. Substrate Substrates (SUBs) can be rigid substrates or flexible substrates that can be bent, folded, or rolled.

[0117] A display layer DISL can be disposed on the main region MA of the substrate SUB. The display layer DISL can be a layer that includes display pixels to display an image. Furthermore, the display layer DISL can be a layer that includes sensor pixels to sense light incident from the outside. The display layer DISL may include a thin-film transistor layer on which thin-film transistors are formed, a light-emitting element layer on which light-emitting elements are formed, and an encapsulation layer for encapsulating the light-emitting element layer.

[0118] In the display area DA of the display layer DISL, not only display pixels can be arranged, but also scan lines, data lines, power lines, etc., connected to the display pixels can be arranged. In the non-display area NDA of the display layer DISL, scan driver units and fan-out lines can be arranged. Scan lines can be connected to the scan driver unit, and fan-out lines can connect data lines to the display driver circuit 320.

[0119] A sensor electrode layer (SENL) can be disposed on the display layer (DISL). The sensor electrode layer (SENL) may include sensor electrodes and is a layer for sensing touch.

[0120] The sensor electrode layer (SENL) may include a touch sensing area and a touch surrounding area. The touch sensing area is the region where sensor electrodes are arranged to sense touch input. The touch surrounding area is the region without sensor electrodes and may be arranged to surround the touch sensing area. The touch surrounding area may extend from the outside of the touch sensing area to the edge of the display panel 300. Sensor electrodes and sensor wiring may be arranged in the touch sensing area. A pad may be arranged in the touch surrounding area.

[0121] The touch sensing area of ​​the sensor electrode layer SENL can be substantially the same as the display area DA of the display panel 300. The touch surrounding area of ​​the sensor electrode layer SENL can be substantially the same as the non-display area NDA of the display panel 300.

[0122] A polarizing film PF can be disposed on the sensor electrode layer SENL. The polarizing film PF may include a first base film, a phase retardation film, a linear polarizing plate, and a second base film stacked sequentially. Each of the first base film and the second base film may be a tri-acetyl-cellulose film, and the phase retardation film may include at least one of a quarter-wave plate and a half-wave plate.

[0123] Alternatively, the sensor electrode layer SENL and the polarizing film PF can be formed as a single unit. In this case, the sensor electrode layer SENL can be disposed between the first base film and the phase retardation film.

[0124] A cover window 100 may be arranged on the polarizing film PF. The cover window 100 may be attached to the polarizing film PF by a transparent adhesive component such as an optically clear adhesive film (OCA).

[0125] A lower panel cover PB may be disposed on the lower part of the display panel 300. The lower panel cover PB can be attached to the lower part of the display panel 300 by means of an adhesive component. The adhesive component may be a pressure-sensitive adhesive (PSA). The lower panel cover PB may include at least one of the following: a light-blocking component for absorbing light incident from the outside, a cushioning component for absorbing impacts from the outside, and a heat dissipation component for effectively releasing heat from the display panel 300.

[0126] A light-blocking component may be disposed at the lower part of the display panel 300. The light-blocking component blocks the transmission of light, thereby preventing components disposed below the light-blocking component (e.g., display circuit board 310, etc.) from being seen from the upper part of the display panel 300. The light-blocking component may include a light-absorbing material such as black pigment or black dye.

[0127] A buffer component can be positioned below the light-blocking component. The buffer component absorbs external impacts to prevent damage to the display panel 300. The buffer component can be configured as a single layer or multiple layers. For example, the buffer component can be formed using polymer resins such as polyurethane, polycarbonate, polypropylene, and polyethylene, or can include elastic materials such as rubber, polyurethane-based materials, or foamed acrylic materials.

[0128] The heat dissipation component can be arranged below the buffer component. The heat dissipation component may include a first heat dissipation layer containing graphite or carbon nanotubes, and a second heat dissipation layer formed using a thin metal film such as copper, nickel, ferrite, or silver that can shield electromagnetic waves and has excellent thermal conductivity.

[0129] The sub-region SBA of the substrate SUB is flexible and can therefore be disposed on the lower surface of the display panel 300. The sub-region SBA of the substrate SUB can be attached to the lower surface of the lower cover PB of the panel via an adhesive layer 391. The adhesive layer 391 can be a pressure-sensitive adhesive.

[0130] Figure 5b This is a cross-sectional view showing the overlay window and display panel according to yet another embodiment.

[0131] See Figure 5b The display panel 300 may include a first substrate SUB1, a display layer DISL, an adhesive component SEAL, a second substrate SUB2, a sensor electrode layer SENL, a polarizing film PF, and a lower cover PB.

[0132] The adhesive component SEAL can bond the first substrate SUB1 and the second substrate SUB2. The adhesive component SEAL can be arranged at the edges of the first substrate SUB1 and the second substrate SUB2 in a manner that surrounds the display layer DISL. The adhesive component SEAL can be a frit adhesive layer, a UV-curable resin, or a thermosetting resin, but is not limited to these.

[0133] The second substrate SUB2 can be made of insulating materials such as glass, quartz, and polymer resin. The second substrate SUB2 can be a rigid substrate or a flexible substrate that can be bent, folded, or rolled.

[0134] A sensor electrode layer SENL may be disposed on the second substrate SUB2. The sensor electrode layer SENL may include sensor electrodes. The sensor electrode layer SENL may be a layer for sensing touch using the sensor electrodes.

[0135] A polarizing film PF can be disposed on the sensor electrode layer SENL. Alternatively, the sensor electrode layer SENL and the polarizing film PF can be formed as one unit.

[0136] The touch circuit board 350 can be attached to the upper surface of the second substrate SUB2 using a low-resistance, high-reliability material such as anisotropic conductive film or self-assembly anisotropic conductive paste (SAP). The touch circuit board 350 is flexible and can be positioned below the display panel 300. The touch circuit board 350 can be connected to the connector 351 of the display circuit board 310. Therefore, the touch circuit board 350 can be electrically connected to the touch driving circuit 330 and the antenna driving circuit 340.

[0137] The sensor electrode layer SENL can be as follows Figure 5a As shown, it is arranged on the display layer DISL or as Figure 5b As shown, it is arranged on the second substrate SUB2. Hereinafter, for ease of explanation, the case where the sensor electrode layer SENL is arranged on the display layer DISL will be mainly described.

[0138] Figure 6 This is a layout diagram showing the sensor electrode layer of a display device according to an embodiment.

[0139] Reference Figure 6 The sensor electrode layer SENL may include sensor electrodes SE and sensor wiring SL, and is driven by a self-capacitance method that senses the voltage charged in the self-capacitance of each of the sensor electrodes SE.

[0140] The sensor electrodes SE can be electrically isolated from each other. The sensor electrodes SE can be arranged spaced apart from each other. The sensor electrodes SE can be arranged in a matrix in a first direction (X-axis direction) and a second direction (Y-axis direction).

[0141] Sensor electrodes SE can be connected one-to-one to sensor wiring SL. Sensor wiring SL can be connected one-to-one to sensor pad TP. That is, one of the sensor wiring SL can connect one of the sensor electrodes SE to one of the sensor pad TP.

[0142] The sensor electrode SE is illustrated as having a quadrilateral planar shape, but is not limited to this. For use as an antenna for 5G mobile communication, the length of the sensor electrode SE in the first direction (X-axis direction) and the length in the second direction (Y-axis direction) can be approximately 2.5 mm to 4.5 mm, respectively. The lengths of the sensor electrode SE in the first direction (X-axis direction) and the second direction (Y-axis direction) can vary depending on the frequency band used for transmission and reception and the material of the sensor electrode SE.

[0143] Each of the sensor electrodes SE can be connected to the sensor wiring SL at the sensor contact SCNT. Figure 6The example illustrates a scenario where each of the sensor electrodes SE is connected to the sensor wiring SL via a single sensor contact SCNT, but it is not limited to this. Each of the sensor electrodes SE can be connected to the sensor wiring SL via multiple sensor contacts SCNT.

[0144] The sensor wiring SL can extend along a second direction (Y-axis direction). The sensor wiring SL can overlap with at least one sensor electrode SE in a third direction (Z-axis direction).

[0145] Grounding voltage can be applied to the first grounding wiring GRL1 and the second grounding wiring GRL2. The second grounding wiring GRL2 can be arranged in the sensor periphery area TPA on the left outer side and the upper side of the sensor periphery area TPA of the sensor area TSA. The first grounding wiring GRL1 can be arranged in the sensor periphery area TPA on the right side of the sensor area TSA.

[0146] The sensor pad region SPA, on which the sensor pad TP is disposed, can be disposed at one end of the sub-region SBA. The sensor pad TP can be connected one-to-one to the bumps of the bump region BP of the display circuit board 310. The sensor pad TP can be electrically connected to the bumps of the display circuit board 310 using an anisotropic conductive film.

[0147] The display circuit board 310 may include a wireless signal connection unit RFC. The wireless signal connection unit RFC can provide touch sensing signals and wireless receiving signals from the sensor electrodes SE to the touch driving circuit 330 and the antenna driving circuit 340.

[0148] like Figure 6 The sensor electrodes SE are electrically connected to the touch driving circuit 330 and antenna driving circuit 340 of the display circuit board 310 via sensor wiring SL, sensor pad TP, bumps in the bump area BP, and wireless signal connection portion RFC. Therefore, the touch driving circuit 330 can apply a touch driving signal to each of the sensor electrodes SE and sense the voltage charging in the self-capacitance of each of the sensor electrodes SE. Furthermore, the antenna driving circuit 340 can sense the wireless receiving signal received by each of the sensor electrodes SE and transmit a wireless transmitting signal to the sensor electrode SE, thereby transmitting a wireless signal.

[0149] As a result, since the wireless signal connection unit RFC, which provides the touch sensing signal and wireless reception signal of the sensor electrode SE to the touch driving circuit 330 and the antenna driving circuit 340, is included, not only can the user's touch be sensed using the sensor electrode SE, but mobile communication can also be performed using the sensor electrode SE. That is, the sensor electrode used for sensing touch can be used as an antenna.

[0150] Furthermore, the antenna drive circuit 340 does not output wireless transmission signals to all sensor electrodes SE, but instead selects the antenna electrode ASE from the sensor electrodes SE and outputs wireless transmission signals to the antenna electrode ASE. This will be discussed later in conjunction with... Figure 9 The wireless signal transmission and reception method of the antenna drive circuit 340 is described.

[0151] Figure 7 It shows in detail Figure 6 Circuit diagram of the wireless signal connection section.

[0152] Reference Figure 7 The display circuit board 310 may include sensor circuit wiring SLP1 to SLPn, wireless signal wiring RFL1 to RFLn, and coupling capacitors Crf1 to Crfn for the wireless signal connection part RFC.

[0153] One end of each of the sensor circuit wirings SLP1 to SLPn can be connected to Figure 6 One end of the bump in the bump area BP is connected to the touch driving circuit 330. The sensor circuit wiring SLP1 to SLPn is connected to the pad TP of the display panel 300 through the bump, so it can be electrically connected to the sensor electrode SE and sensor wiring SL of the display panel 300.

[0154] One end of each of the wireless signal wirings RFL1 to RFLn can be connected to one of the coupling capacitors Crf1 to Crfn, and the other end can be connected to the antenna drive circuit 340.

[0155] Each of the coupling capacitors Crf1 to Crfn can be a capacitor formed by overlapping or adjacent wiring arrangements, or a capacitor formed as a separate physical circuit element. One electrode of each of the coupling capacitors Crf1 to Crfn can be connected to one of the wireless signal wirings RFL1 to RFLn, and the other electrode can be connected to one of the sensor circuit wirings SLP1 to SLPn. For example, the first coupling capacitor Crf1 can be formed between the first wireless signal wiring RFL1 and the first sensor circuit wiring SLP1. The second coupling capacitor Crf2 can be formed between the second wireless signal wiring RFL2 and the second sensor circuit wiring SLP2. The (n-1)th coupling capacitor Crfn-1 can be formed between the (n-1)th wireless signal wiring RFLn-1 and the (n-1)th sensor circuit wiring SLPn-1. The nth coupling capacitor Crfn can be formed between the nth wireless signal wiring RFLn and the nth sensor circuit wiring SLPn.

[0156] The touch sensing signal and wireless receiving signal of the sensor electrodes SE, which are electrically connected to the sensor circuit wirings SLP1 to SLPn, can be coupled to the wireless signal wirings RFL1 to RFLn through coupling capacitors Crf1 to Crfn. Accordingly, even if the antenna driving circuit 340 is not directly connected to the sensor circuit wirings SLP1 to SLPn, it can still receive the touch sensing signal and wireless receiving signal of the sensor electrodes SE.

[0157] Furthermore, the wireless transmission signals from the wireless signal wirings RFL1 to RFLn output from the antenna drive circuit 340 can be coupled to the sensor circuit wirings SLP1 to SLPn via coupling capacitors Crf1 to Crfn. Therefore, even if the sensor circuit wirings SLP1 to SLPn are not directly connected to the antenna drive circuit 340, the wireless transmission signals can still be transmitted to the sensor electrodes SE.

[0158] like Figure 7 As shown, by forming coupling capacitors Crf1 to Crfn between the sensor circuit wiring SLP1 to SLPn and the wireless signal wiring RFL1 to RFLn, the signal of the sensor circuit wiring SLP1 to SLPn can be coupled to the wireless signal wiring RFL1 to RFLn through the coupling capacitors Crf1 to Crfn, and the signal of the wireless signal wiring RFL1 to RFLn can be coupled to the sensor circuit wiring SLP1 to SLPn through the coupling capacitors Crf1 to Crfn.

[0159] Figure 8 This is a diagram illustrating an example of the frequencies of touch drive signals and touch sensing signals applied to sensor electrodes according to an embodiment, as well as the frequencies of wireless transmission signals and wireless reception signals.

[0160] Reference Figure 8 The touch driving signal and touch sensing signal have frequencies of approximately 50–500 kHz. In contrast, the wireless transmission and reception signals used in fifth-generation mobile communications such as 5G can have frequencies of 3–100 GHz. That is, the touch driving signal and touch sensing signal have frequencies below 1 MHz, while the wireless transmission and reception signals used in fifth-generation mobile communications can have frequencies above 1 GHz. Therefore, the touch driving circuit 330, which transmits and receives touch driving signals and touch sensing signals with frequencies below 1 MHz, and the antenna driving circuit 340, which transmits and receives wireless transmission and reception signals with frequencies above 1 GHz, can achieve frequency division duplex.

[0161] The touch driving circuit 330 may include a low-pass filter that allows only signals with frequencies below 1 MHz from the signals received from the sensor circuit wirings SLP1 to SLPn to pass through, or a band-pass filter that filters only the desired frequency band. In this case, due to the attenuation of wireless transmission and reception signals with frequencies above 1 GHz, the touch driving circuit 330 can stably receive touch sensing signals with frequencies below 1 MHz.

[0162] Furthermore, the antenna driving circuit 340 may include a high-pass filter that only allows signals with frequencies above 1 MHz from the signals received from the wireless signal wiring RFL1 to RFLn to pass through, or a band-pass filter that only filters the desired frequency band. In this case, due to the attenuation of touch driving signals and touch sensing signals with frequencies below 1 MHz, the antenna driving circuit 340 can stably receive wireless received signals with frequencies above 1 MHz.

[0163] The antenna drive circuit 340 can perform the function of selecting the antenna electrode ASE for transmitting and receiving electromagnetic waves from the sensor electrode SE. In this case, the antenna drive circuit 340 can select the antenna electrode ASE from the sensor electrode SE by taking into account factors such as receiving sensitivity, the position of the sensor electrode SE, and the tilt angle of the display device 10. (See below for reference.) Figures 9 to 18 The method for the antenna drive circuit 340 to select the antenna electrode ASE from the sensor electrode SE is described in detail.

[0164] Figure 9 This is a flowchart illustrating a wireless signal transmission and reception method according to an embodiment.

[0165] Reference Figure 9 First, the antenna drive circuit 340 receives wireless reception signals from the sensor electrode SE. Figure 9 (S101).

[0166] The wireless received signal from the sensor electrode SE can be transmitted to the sensor circuit wirings SLP1 to SLPn on the display circuit board 310 via the sensor wiring SL and sensor pad TP. The wireless received signal from the sensor circuit wirings SLP1 to SLPn can be coupled to the wireless signal wirings RFL1 to RFLn via coupling capacitors Crf1 to Crfn. The antenna drive circuit 340 can receive the wireless received signal coupled to the wireless signal wirings RFL1 to RFLn.

[0167] Second, the antenna drive circuit 340 outputs the wireless received signal from the antenna electrode ASE to the mobile communication module. Figure 9 (S102).

[0168] Before performing wireless communication, as in step S103, the antenna driving circuit 340 can pre-set the antenna electrode ASE, which will be used as an antenna, in the sensor electrode SE. The antenna electrode ASE can be an electrode that transmits electromagnetic waves according to a wireless transmission signal and receives electromagnetic waves according to a wireless reception signal. Therefore, the sensor electrode SE can be defined as an electrode that receives a touch drive signal for touch sensing, and the antenna electrode ASE can be defined as an electrode that not only receives a touch drive signal for touch sensing but also transmits electromagnetic waves by receiving wireless transmission signals for mobile communication.

[0169] The sensor region TSA can include I×J sensor electrodes SE, and a portion of the sensor electrodes SE functions as antenna electrodes ASE. For example, as Figure 10 and Figure 11 As shown, the sensor electrode SE can include P × Q antenna electrodes ASE (where P is a positive integer less than 1 and Q is a positive integer less than J). For example, as... Figure 10 As shown, the sensor area TSA can include 8×10 sensor electrodes SE, and among the sensor electrodes SE, 4×4 sensor electrodes SE serve as antenna electrodes ASE.

[0170] Or, such as Figures 12 to 14 As shown, the sensor electrode SE may include multiple sub-antenna electrode groups SAG1 to SAG4. Each of the multiple sub-antenna electrode groups SAG1 to SAG4 may include multiple antenna electrodes ASE.

[0171] like Figure 10 As shown, the antenna driving circuit 340 can change the frequency of each of the wireless received signals of the antenna electrode ASE and amplify the amplitude before outputting it to the mobile communication module 720. The antenna driving circuit 340 can also change the phase of each of the wireless received signals of the antenna electrode ASE.

[0172] Third, the antenna drive circuit 340 analyzes the wireless received signal and selects the antenna electrode ASE. Figure 9 (S103).

[0173] The antenna driving circuit 340 can analyze the wireless received signals of all sensor electrodes SE to select the antenna electrode ASE to be used as the antenna. For example, the antenna driving circuit 340 can select the antenna electrode ASE by considering the receiving sensitivity or quality of the wireless received signals of all sensor electrodes SE. It can be considered that the higher the receiving sensitivity of the wireless received signal, the more suitable the location is for communication with an external base station. Therefore, the antenna driving circuit 340 can select the sensor electrode SE that receives a wireless received signal with higher receiving sensitivity as the antenna electrode ASE. A wireless received signal with higher receiving sensitivity indicates a relatively strong wireless received signal.

[0174] Fourth, output wireless transmission signals to the antenna electrode ASE. Figure 9 (S104).

[0175] like Figure 10 As shown, the antenna driving circuit 340 can receive wireless transmission signals from the mobile communication module 720, change the frequency of the wireless transmission signals, and output them to the selected antenna electrode ASE. Therefore, electromagnetic waves can be transmitted to an external base station through the selected antenna electrode ASE.

[0176] like Figure 9 As shown, the antenna driving circuit 340 can select the sensor electrode SE with the best receiving sensitivity from the sensor electrode SE as the antenna electrode ASE and use it as an antenna to transmit electromagnetic waves, thereby improving the antenna performance of the display device 10.

[0177] in addition, Figure 9 The example illustrates the scenario where the antenna driving circuit 340 continuously and repeatedly executes steps S101 to S104, but it is not limited to this. For example, step S103 may be executed only if the mobile communication module 720 or the antenna driving circuit 340 determines that the sensitivity or quality of the wireless received signal received through the antenna electrode ASE is low, thereby selecting the antenna electrode ASE to be used as the antenna.

[0178] The following, combined with Figures 10 to 14 An example of the sensor electrode SE and the antenna electrode ASE will be described. Figures 10 to 14 This is an example diagram showing the antenna electrode ASE selected from the sensor electrode SE as described in step S103 in order to improve the sensitivity or quality of wireless received signals.

[0179] Figure 10 This is a layout diagram showing the sensor electrodes and antenna electrodes according to one embodiment.

[0180] exist Figure 10For ease of explanation, an example is given of the sensor region TSA including 8 × 10 sensor electrodes SE, but it is not limited to this case.

[0181] Reference Figure 10 The sensor electrodes SE can be arranged in a matrix in a first direction (X-axis direction) and a second direction (Y-axis direction). In the first direction (X-axis direction), I (I is a positive integer) sensor electrodes SE can be neatly arranged, and in the second direction (Y-axis direction), J (J is a positive integer) sensor electrodes SE can be neatly arranged. For example, as... Figure 10 As shown, in the first direction (X-axis direction), 8 sensor electrodes SE can be neatly arranged, and in the second direction (Y-axis direction), 10 sensor electrodes SE can be neatly arranged.

[0182] The sensor electrode SE may include P × Q antenna electrodes ASE. The antenna electrodes ASE can be arranged in a matrix configuration in a first direction (X-axis direction) and a second direction (Y-axis direction). In the first direction (X-axis direction), P antenna electrodes ASE can be neatly arranged, and in the second direction (Y-axis direction), Q antenna electrodes ASE can be neatly arranged. For example, as... Figure 10 As shown, in the first direction (X-axis direction), the four antenna electrodes ASE can be neatly arranged, and in the second direction (Y-axis direction), the four antenna electrodes ASE can be neatly arranged.

[0183] In this specification, the sensor electrode SE can be defined as an electrode that receives touch drive signals for touch sensing, and the antenna electrode ASE can be defined as an electrode that not only receives touch drive signals for touch sensing but also receives wireless transmission signals for mobile communication to transmit electromagnetic waves.

[0184] The antenna electrode ASE can be arranged in the center of one side of the sensor region TSA. For example, the antenna electrode ASE can be arranged in the center of the upper side of the sensor region TSA. That is, a portion of the sensor electrodes SE arranged at the uppermost side of the sensor region TSA can be selected as the antenna electrode ASE.

[0185] like Figure 10 As shown, when P×Q antenna electrodes ASE are continuously arranged in the first direction (X-axis direction) and the second direction (Y-axis direction), the intensity of the electromagnetic wave emitted by the antenna electrodes ASE can be relatively large, and the electromagnetic wave can be emitted in a predetermined direction. Therefore, Figure 10 The embodiment is advantageous when the location of an external base station is known and the display device 10 emits electromagnetic waves in the direction of the external base station.

[0186] Figure 11 This is a layout diagram showing the sensor electrodes and antenna electrodes according to yet another embodiment.

[0187] Figure 11 Implementation examples and Figure 10 The difference in the embodiments is that the antenna electrode ASE is arranged adjacent to one side of the sensor region TSA, but none of the sensor electrodes SE arranged on the far side of the sensor region TSA are selected as antenna electrodes ASE.

[0188] Reference Figure 11 The antenna electrode ASE can be arranged adjacent to the lower side of the sensor region TSA, but none of the sensor electrodes SE arranged at the bottom of the sensor region TSA are selected as antenna electrodes ASE.

[0189] Alternatively, the antenna electrode ASE can be arranged closer to the central region of the sensor region TSA than to the four sides of the sensor region TSA.

[0190] Figure 12 This is a layout diagram showing the sensor electrodes and antenna electrodes according to yet another embodiment.

[0191] Figure 12 Implementation examples and Figure 10 The difference in the embodiments is that the sensor electrode SE includes multiple sub-antenna electrode groups SAG1 to SAG4.

[0192] Reference Figure 12 The sensor electrode SE may include multiple sub-antenna electrode groups SAG1 to SAG4. Each of the multiple sub-antenna electrode groups SAG1 to SAG4 may include R×S (R is a positive integer less than 1, and S is a positive integer less than J) antenna electrodes ASE. R represents the number of antenna electrodes ASE arranged along the first direction (X-axis direction), and S represents the number of antenna electrodes ASE arranged along the second direction (Y-axis direction). For example, as... Figure 12 As shown, each of the multiple sub-antenna electrode groups SAG1 to SAG4 may include 2×2 antenna electrodes ASE.

[0193] Multiple sub-antenna electrode groups SAG1 to SAG4 can be arranged spaced apart from each other. For example, multiple sub-antenna electrode groups SAG1 to SAG4 can be arranged at the corners of the sensor region TSA. For example, the first sub-antenna electrode group SAG1 can be arranged at the corner where the upper and left sides of the sensor region TSA meet, the second sub-antenna electrode group SAG2 can be arranged at the corner where the upper and right sides of the sensor region TSA meet, the third sub-antenna electrode group SAG3 can be arranged at the corner where the lower and left sides of the sensor region TSA meet, and the fourth sub-antenna electrode group SAG4 can be arranged at the corner where the lower and right sides of the sensor region TSA meet.

[0194] like Figure 12As shown, when multiple sub-antenna electrode groups SAG1 to SAG4 are respectively arranged at the corners of the sensor region TSA, electromagnetic waves emitted by the multiple sub-antenna electrode groups SAG1 to SAG4 can be emitted in multiple directions. Therefore, Figure 12 The embodiment is advantageous when the location of the external base station is unknown and the display device 10 emits electromagnetic waves in multiple directions.

[0195] Figure 13 This is a layout diagram showing the sensor electrodes and antenna electrodes according to yet another embodiment.

[0196] Figure 13 Implementation examples and Figure 12 The difference in the embodiments is that the multiple sub-antenna electrode groups SAG1 to SAG4 extend longer in one direction.

[0197] Reference Figure 13 The antenna electrodes ASE of each of the multiple sub-antenna electrode groups SAG1 to SAG4 can be arranged along the second direction (Y-axis direction). For example, as Figure 13 As shown, each of the plurality of sub-antenna electrode groups SAG1 to SAG4 may include 1×4 antenna electrodes ASE. In this case, sensor electrodes SE may be arranged between adjacent sub-antenna electrode groups in the first direction (X-axis direction). For example, 1×4 sensor electrodes SE may be arranged between the first sub-antenna electrode group SAG1 and the second sub-antenna electrode group SAG2.

[0198] Alternatively, the antenna electrodes ASE of each of the multiple sub-antenna electrode groups SAG1 to SAG4 can be arranged along a first direction (X-axis direction). In this case, the sensor electrode SE can be arranged between adjacent sub-antenna electrode groups in the second direction (Y-axis direction) of the multiple sub-antenna electrode groups SAG1 to SAG4.

[0199] like Figure 13 As shown, with each of the multiple sub-antenna electrode groups SAG1 to SAG4 extending relatively long in one direction, and the sensor electrode SE arranged at each of the multiple sub-antenna electrode groups SAG1 to SAG4, electromagnetic waves can be received over a wider area. Therefore, Figure 13 This embodiment is advantageous when the location of the external base station is unknown and the display device 10 needs to receive electromagnetic waves over a wider area.

[0200] Figure 14 This is a layout diagram showing the sensor electrodes and antenna electrodes according to yet another embodiment.

[0201] Figure 14 Implementation examples and Figure 10The difference in the embodiments is that the antenna electrodes ASE are arranged spaced apart from each other.

[0202] Reference Figure 14 At least one sensor electrode SE may be arranged between adjacent antenna electrodes ASE in the first direction (X-axis direction). Furthermore, at least one sensor electrode SE may be arranged between adjacent antenna electrodes ASE in the second direction (Y-axis direction).

[0203] like Figure 14 As shown, when the antenna electrodes (ASE) are arranged spaced apart from each other, electromagnetic waves can be received over a wider area. Therefore, Figure 14 This embodiment is advantageous when the location of the external base station is unknown and the display device 10 needs to receive electromagnetic waves over a wider area.

[0204] Figure 15 This is a flowchart illustrating a wireless signal transceiver method according to yet another embodiment.

[0205] Figure 15 Implementation examples and Figure 9 The difference in the embodiment is that step S203 analyzes not only the wireless received signal of the sensor electrode SE, but also the touch coordinate data to select the antenna electrode ASE.

[0206] Reference Figure 15 When selecting an antenna electrode ASE, the antenna driving circuit 340 can exclude sensor electrodes SE where a touch has occurred based on the touch coordinate information from the touch coordinate data. If a person or object is located on a sensor electrode SE where a touch has occurred, the emitted electromagnetic waves may be absorbed or reflected by the person or object, potentially degrading the antenna's performance. Therefore, the antenna driving circuit 340 can exclude sensor electrodes SE where a touch has occurred and select an antenna electrode ASE by considering the receiving sensitivity of the wireless receiving signal of the remaining sensor electrodes SE.

[0207] Figure 16 This is a flowchart illustrating a wireless signal transceiver method according to yet another embodiment.

[0208] Figure 16 Implementation examples and Figure 9 The difference in the embodiment is that step S303 analyzes not only the wireless received signal of the sensor electrode SE, but also the acceleration data of the accelerometer 740 and the angular velocity data of the gyroscope sensor 750 to select the antenna electrode ASE.

[0209] Reference Figure 16When selecting an antenna electrode ASE, the antenna drive circuit 340 can determine the tilt and rotation direction of the display device 10 based on the acceleration data from the accelerometer 740 and the angular velocity data from the gyroscope 750. The antenna drive circuit 340 can exclude sensor electrodes SE arranged near the ground from the sensor electrodes SE based on the tilt and rotation direction of the display device 10. Electromagnetic waves emitted from sensor electrodes SE arranged near the ground are absorbed or reflected by the ground, potentially degrading antenna performance. Therefore, the antenna drive circuit 340 can select an antenna electrode ASE by excluding sensor electrodes SE arranged near the ground and considering the receiving sensitivity of the wireless receiving signal of the remaining sensor electrodes SE.

[0210] Alternatively, the antenna driving circuit 340 can select a sensor electrode SE positioned at a relatively high position from the sensor electrodes SE as a candidate sensor electrode SE based on the tilt and rotation direction of the display device 10. Electromagnetic waves emitted by the sensor electrode SE positioned at a higher position can be emitted stably due to the absence of interfering structures. Therefore, the antenna driving circuit 340 can select the antenna electrode SE by considering the receiving sensitivity of the wireless signal of the candidate sensor electrode SE.

[0211] Figure 17 This is a flowchart illustrating a wireless signal transceiver method according to yet another embodiment. Figure 18 This is a layout diagram showing the first antenna electrode and the second antenna electrode according to one embodiment.

[0212] Reference Figure 17 and Figure 18 First, receive a first wireless signal and a second wireless signal from the sensor electrode SE. Figure 17 (S401).

[0213] The first and second wireless received signals from the sensor electrode SE can be transmitted to the sensor circuit wirings SLP1-SLPn on the display circuit board 310 via the sensor wiring SL and the sensor pad TP. The first and second wireless received signals from the sensor circuit wirings SLP1-SLPn can be coupled to the wireless signal wirings RFL1-RFLn via coupling capacitors Crf1-Crfn. The antenna drive circuit 340 can receive the first and second wireless received signals coupled to the wireless signal wirings RFL1-RFLn.

[0214] The first wireless received signal can be a signal with a frequency of approximately 5 to 30 GHz, and the second wireless received signal can be a signal with a frequency of approximately 30 to 70 GHz. Since the frequencies of the first and second wireless received signals are distinguished, the antenna drive circuit 340 for transmitting and receiving the first and second wireless received signals can implement frequency division duplex (FDM). In this case, the display device 10 may include a first mobile communication module 720 for receiving the first wireless received signal and transmitting a first wireless transmitted signal, and a second mobile communication module 721 for receiving the second wireless received signal and transmitting a second wireless transmitted signal.

[0215] Second, the first wireless received signal of the first antenna electrode ASE1 is output to the first mobile communication module 720. Figure 17 (S402).

[0216] Before performing wireless communication, as in step S404, the antenna driving circuit 340 can pre-set the first antenna electrode ASE1, which will be used as the first antenna, in the sensor electrode SE. For example, as... Figure 18 As shown, the sensor electrode SE may include a first antenna electrode ASE1 located at the left and upper corners of the sensor region TSA and at the right and upper corners. The location of the first antenna electrode ASE1 is not limited to... Figure 18 As shown. For example, the first antenna electrode ASE1 can be as follows: Figure 10 As shown, it is arranged in the center of one side of the sensor area TSA, or as... Figure 11 The antenna electrode ASE1 is arranged adjacent to the central region of the sensor area TSA, as shown. Alternatively, the first antenna electrode ASE1 can be arranged as follows: Figure 13 The diagram shows sub-antenna electrode groups that extend elongatedly along one direction. Alternatively, the first antenna electrode ASE1 can be as follows: Figure 14 The areas shown are arranged separately from each other.

[0217] like Figure 18 As shown, the antenna driving circuit 340 can change the frequency of each of the first wireless received signals of the first antenna electrode ASE1 and amplify the amplitude before outputting it to the first mobile communication module 720.

[0218] Third, the second wireless receiving signal of the second antenna electrode ASE2 is output to the second mobile communication module 721. Figure 17 (S403).

[0219] Before performing wireless communication, as in step S404, the antenna driving circuit 340 can pre-set the second antenna electrode ASE2, which will be used as the second antenna, in the sensor electrode SE. For example, as... Figure 18As shown, the sensor electrode SE may include a second antenna electrode ASE2 located at the left and lower corners of the sensor region TSA and at the right and lower corners. The location of the second antenna electrode ASE2 is not limited to... Figure 18 As shown. For example, the second antenna electrode ASE2 can be as follows: Figure 10 As shown, it is arranged in the center of one side of the sensor area TSA, or as... Figure 11 The electrode is arranged adjacent to the central region of the sensor area TSA, as shown. Alternatively, the second antenna electrode ASE2 can be arranged as follows: Figure 13 The diagram shows sub-antenna electrode groups that extend elongated along one direction. Alternatively, the second antenna electrode ASE2 can be as follows: Figure 14 The areas shown are arranged separately from each other.

[0220] like Figure 18 As shown, the antenna driving circuit 340 can change the phase of each of the second wireless received signals of the second antenna electrode ASE2 and amplify the amplitude before outputting it to the second mobile communication module 721.

[0221] Fourth, the first antenna electrode ASE1 is selected based on the analysis of the first wireless received signal, and the second antenna electrode ASE2 is selected based on the analysis of the second wireless received signal. Figure 17 (S404).

[0222] The antenna driving circuit 340 can analyze the wireless received signals of all sensor electrodes SE to select the first antenna electrode ASE1 to be used as the first antenna and the second antenna electrode ASE2 to be used as the second antenna. For example, the antenna driving circuit 340 can select the first antenna electrode ASE1 and the second antenna electrode ASE2 by taking into account the receiving sensitivity of the wireless received signals of all sensor electrodes SE.

[0223] Fifth, output the first wireless transmission signal to the first antenna electrode ASE1 and output the second wireless transmission signal to the second antenna electrode ASE2. Figure 17 (S405).

[0224] like Figure 18 As shown, the antenna driving circuit 340 can receive a first wireless transmission signal from the first mobile communication module 720, change the phase of the first wireless transmission signal, amplify its amplitude, and output it to the selected first antenna electrode ASE1. Therefore, the first wireless transmission signal can be transmitted to an external base station through the selected first antenna electrode ASE1.

[0225] And, as Figure 18As shown, the antenna driving circuit 340 can receive the second wireless transmission signal from the second mobile communication module 721, change the phase of the second wireless transmission signal, amplify its amplitude, and output it to the second antenna electrode ASE2. Therefore, the second wireless transmission signal can be transmitted to an external base station through the selected second antenna electrode ASE2.

[0226] like Figure 17 and Figure 18 As shown, the antenna driving circuit 340 can receive a first wireless reception signal and transmit a first wireless transmission signal using the first antenna electrode ASE1. Furthermore, the antenna driving circuit 340 can receive a second wireless reception signal and transmit a second wireless transmission signal using the second antenna electrode ASE2. That is, a portion of the sensor electrodes used for sensing touch can be used as a first antenna, and another portion can be used as a second antenna for transmitting and receiving electromagnetic waves at frequencies different from the first antenna.

[0227] Figure 19 It is shown Figure 6 This is a layout diagram of an example of sensor wiring, sensor electrodes, and sensor contacts. Figure 20 It shows along Figure 19 The I-I' section is a cross-sectional view of an example of a display panel.

[0228] For ease of explanation, Figure 19 and Figure 20 The diagram only shows one sensor electrode SE and one sensor wiring SL.

[0229] Reference Figure 19 and Figure 20 The sensor electrode SE can be connected to the sensor wiring SL through the sensor contact SCNT.

[0230] A display layer DISL, comprising a thin-film transistor layer (TFTL), a light-emitting element layer (EML), and a packaging layer (TFEL), can be disposed on the substrate SUB. A sensor electrode layer SENL, comprising sensor electrodes (SE), is disposed on the display layer DISL.

[0231] A first buffer film BF1 may be disposed on one side of the substrate SUB, and a second buffer film BF2 may be disposed on the first buffer film BF1. The first buffer film BF1 and the second buffer film BF2 are disposed on one side of the substrate SUB to protect the thin-film transistors of the thin-film transistor layer (TFTL) and the light-emitting layer 172 of the light-emitting element layer (EML) from moisture permeating through the moisture-permeable substrate SUB. The buffer films may comprise multiple inorganic films stacked alternately. For example, each of the first buffer film BF1 and the second buffer film BF2 may be formed using a multilayer film of one or more inorganic films, such as silicon nitride, silicon oxynitride, silicon oxide, titanium oxide, and aluminum oxide, stacked alternately. At least one of the first buffer film BF1 and the second buffer film BF2 may be omitted.

[0232] A light-blocking layer BML can be disposed on the first buffer film BF1. The light-blocking layer BML can be formed as a single layer or multiple layers made of one or an alloy of molybdenum (Mo), aluminum (Al), chromium (Cr), gold (Au), titanium (Ti), nickel (Ni), neodymium (Nd) and copper (Cu). Alternatively, the light-blocking layer BML can be an organic film including black pigment.

[0233] An active layer ACT, comprising a thin-film transistor ST for displaying pixels, can be disposed on the second buffer film BF2. The active layer ACT may comprise polycrystalline silicon, monocrystalline silicon, low-temperature polycrystalline silicon, amorphous silicon, or oxide semiconductor material. When the active layer ACT comprises polycrystalline silicon or oxide semiconductor material, the regions in the active layer ACT doped with ions may be conductive regions.

[0234] The active layer ACT can overlap with the light-blocking layer BML in the third direction (Z-axis direction). Since the light incident through the substrate SUB can be blocked by the light-blocking layer BML, leakage current can be prevented from flowing through each of the active layers ACT by means of the light incident through the substrate SUB.

[0235] A gate insulating film 130 may be formed on the active layer ACT of the thin-film transistor ST. The gate insulating film 130 may be formed using an inorganic film (e.g., a silicon nitride layer, a silicon oxynitride layer, a silicon oxide layer, a titanium oxide layer, or an aluminum oxide layer).

[0236] The gate electrode G of the thin-film transistor ST can be disposed on the gate insulating film 130. The gate electrode G of the thin-film transistor ST can overlap with the active layer ACT in the third direction (Z-axis direction). The portion of the active layer ACT that overlaps with the gate electrode G in the third direction (Z-axis direction) can be the channel region CHA. The gate electrode G of the thin-film transistor ST can be formed as a single layer or multiple layers using one of molybdenum (Mo), aluminum (Al), chromium (Cr), gold (Au), titanium (Ti), nickel (Ni), neodymium (Nd), and copper (Cu) or their alloys.

[0237] A first interlayer insulating film 141 may be disposed on the gate electrode G of the thin-film transistor ST. The first interlayer insulating film 141 may be formed using an inorganic film (e.g., a silicon nitride layer, a silicon oxynitride layer, a silicon oxide layer, a titanium oxide layer, or an aluminum oxide layer). The first interlayer insulating film 141 may include multiple inorganic films.

[0238] An electrode CE of a capacitor can be disposed on the first interlayer insulating film 141. The electrode CE of the capacitor can overlap with the gate electrode G of the thin-film transistor ST in the third direction (Z-axis direction). The electrode CE of the capacitor can be formed as a single layer or multiple layers made of one or an alloy of molybdenum (Mo), aluminum (Al), chromium (Cr), gold (Au), titanium (Ti), nickel (Ni), neodymium (Nd) and copper (Cu).

[0239] A second interlayer insulating film 142 may be disposed on one electrode CE of the capacitor. The second interlayer insulating film 142 may be formed using an inorganic film (e.g., a silicon nitride layer, a silicon oxynitride layer, a silicon oxide layer, a titanium oxide layer, or an aluminum oxide layer). The second interlayer insulating film 142 may include multiple inorganic films.

[0240] The first electrode S and the second electrode D of the thin-film transistor ST can be arranged on the second interlayer insulating film 142. The first electrode S and the second electrode D of the thin-film transistor ST can be formed as a single layer or multiple layers using one of molybdenum (Mo), aluminum (Al), chromium (Cr), gold (Au), titanium (Ti), nickel (Ni), neodymium (Nd) and copper (Cu) or their alloys.

[0241] The first electrode S of the thin-film transistor ST can be connected to a first conductive region COA1 disposed on one side of the channel region CHA of the active layer ACT through a contact hole that penetrates the gate insulating film 130, the first interlayer insulating film 141, and the second interlayer insulating film 142. The second electrode D of the thin-film transistor ST can be connected to a second conductive region COA2 disposed on the other side of the channel region CHA of the active layer ACT through a contact hole that penetrates the gate insulating film 130, the first interlayer insulating film 141, and the second interlayer insulating film 142.

[0242] A first organic film 150 for planarizing the step difference generated by the thin-film transistor ST can be disposed on the first electrode S and the second electrode D. The first organic film 150 can be formed using organic films such as acrylic resin, epoxy resin, phenolic resin, polyamide resin, and polyimide resin.

[0243] A first connection electrode ANDE1 may be disposed on the first organic film 150. The first connection electrode ANDE1 can be connected to the second electrode D of the thin-film transistor ST through a contact hole penetrating the first organic film 150. The first connection electrode ANDE1 may be formed as a single layer or multiple layers using one of molybdenum (Mo), aluminum (Al), chromium (Cr), gold (Au), titanium (Ti), nickel (Ni), neodymium (Nd) and copper (Cu) or their alloys.

[0244] A second organic film 160 may be disposed on the first connecting electrode ANDE1. The second organic film 160 may be formed using organic films such as acrylic resin, epoxy resin, phenolic resin, polyamide resin, and polyimide resin.

[0245] A light-emitting element layer (EML) is disposed on the thin-film transistor layer (TFTL). The light-emitting element layer (EML) may include light-emitting elements 170 and 180.

[0246] Each of the light-emitting elements 170 may include a first light-emitting electrode 171, a light-emitting layer 172, and a second light-emitting electrode 173.

[0247] The first light-emitting electrode 171 can be formed on the second organic film 160. The first light-emitting electrode 171 can be connected to the first connecting electrode ANDE1 through a contact hole penetrating the second organic film 160.

[0248] In the top emission structure that emits light from the light-emitting layer 172 toward the second light-emitting electrode 173, the first light-emitting electrode 171 can be formed as a single layer of molybdenum (Mo), titanium (Ti), copper (Cu), or aluminum (Al), or, to improve reflectivity, it can be formed as a stacked structure of aluminum and titanium (Ti / Al / Ti), a stacked structure of aluminum and indium tin oxide (ITO) (ITO / Al / ITO), an APC alloy, or a stacked structure of APC alloy and ITO (ITO / APC / ITO). The APC alloy is an alloy of silver (Ag), palladium (Pd), and copper (Cu).

[0249] The dam 180 serves to define the light-emitting region EA of the display pixel. The light-emitting region EA represents the area where the first light-emitting electrode 171, the light-emitting layer 172, and the second light-emitting electrode 173 are stacked sequentially, and holes from the first light-emitting electrode 171 and electrons from the second light-emitting electrode 173 combine with each other in the light-emitting layer 172 to emit light. In this case, the first light-emitting electrode 171 can be an anode electrode, and the second light-emitting electrode 173 can be a cathode electrode.

[0250] The dam 180 can be formed as a portion of the first light-emitting electrode 171 exposed on the second organic film 160. The dam 180 can cover the edge portion of the first light-emitting electrode 171. The dam 180 can be disposed in a contact hole penetrating the second organic film 160. Accordingly, the contact hole penetrating the second organic film 160 can be filled by the dam 180. The dam 180 can be formed using organic films such as acrylic resin, epoxy resin, phenolic resin, polyamide resin, and polyimide resin.

[0251] A light-emitting layer 172 is formed on the first light-emitting electrode 171. The light-emitting layer 172 may include an organic material to emit light of a predetermined color. For example, the light-emitting layer 172 may include a hole transport layer, an organic material layer, and an electron transport layer. The organic material layer may include a host and a dopant. The organic material layer may include a material that emits predetermined light and may be formed using phosphorescent or fluorescent materials.

[0252] For example, the first emitting region RE (referencing) that emits light of the first color. Figure 43The organic material layer of the luminescent layer 172 may include a host material and a phosphorescent material as a dopant. The host material includes carbazole biphenyl (CBP) or 1,3-bis(carbazol-9-yl)benzene (mCP). The phosphorescent material includes one or more selected from bis(1-phenylisoquinoline)acetylacetonate iridium (PIQIr(acac): bis(1-phenylisoquinoline)acetylacetonate iridium, bis(1-phenylquinoline)acetylacetonate iridium (PQIr(acac): bis(1-phenylquinoline)acetylacetonate iridium, tris(1-phenylquinoline)iridium (PQIr): tris(1-phenylquinoline)iridium, and octaethylporphyrinplatinum (PtOEP). Alternatively, the organic material layer of the luminescent layer 172 of the first luminescent region RE may include a fluorescent material containing PBD:Eu(DBM)3(Phen) or perylene as a dopant material, but is not limited thereto.

[0253] The second luminescent region GE (refer to) emits light of the second color. Figure 43 The organic material layer of the luminescent layer 172 may include a host material and a phosphorescent material as a dopant, wherein the host material includes CBP or mCP, and the phosphorescent material includes Ir(ppy)3 (tris(2-phenylpyridine)iridium). Alternatively, the organic material layer of the luminescent layer 172 of the second luminescent region GE, which emits light of a second color, may include a fluorescent material containing tris(8-hydroxyquinolino)aluminum as a dopant, but is not limited thereto.

[0254] The third emitting region BE (refer to) emits light of the third color. Figure 43 The organic material layer of the light-emitting layer 172 may include a host material and a phosphorescent material as a dopant material. The host material may include CBP or mCP, and the phosphorescent material may include (4,6-F2ppy)2Irpic or L2BD111, but is not limited thereto.

[0255] The second light-emitting electrode 173 is formed on the light-emitting layer 172. The second light-emitting electrode 173 may be formed to cover the light-emitting layer 172. The second light-emitting electrode 173 may be a common layer formed together with the display pixels. A capping layer may be formed on the second light-emitting electrode 173.

[0256] In the upper light-emitting structure, the second light-emitting electrode 173 may include a transparent conductive material (TCO) such as ITO or IZO that allows light to pass through, or a semi-transmissive conductive material such as magnesium (Mg), silver (Ag), or an alloy of magnesium (Mg) and silver (Ag). When the second light-emitting electrode 173 is formed using a semi-transmissive conductive material, the light extraction efficiency can be improved through a microcavity.

[0257] An encapsulation layer TFEL can be formed on the light-emitting element layer EML. The encapsulation layer TFEL may include at least one inorganic film to prevent oxygen or moisture from penetrating into the light-emitting element layer EML. Furthermore, the encapsulation layer TFEL may include at least one organic film to protect the light-emitting element layer EML from foreign matter such as dust.

[0258] Alternatively, a substrate can be disposed on the light-emitting element layer (EML) instead of the encapsulation layer (TFEL), and the space between the EML and the substrate can be either empty in a vacuum state or filled with a filling film. The filling film can be an epoxy filling film or a silicone filling film.

[0259] A sensor electrode layer SENL is arranged on the encapsulation layer TFEL. The sensor electrode layer SENL may include a third buffer film BF3, sensor wiring SL, sensor electrode SE, a first sensor insulating film TINS1, and a second sensor insulating film TINS2.

[0260] A third buffer film BF3 may be disposed on the encapsulation layer TFEL. The third buffer film BF3 may include at least one inorganic film. For example, the third buffer film BF3 may be formed by a multilayer film consisting of one or more inorganic films, such as silicon nitride, silicon oxynitride, silicon oxide, titanium oxide, and aluminum oxide, stacked alternately. The third buffer film BF3 may be omitted.

[0261] Sensor wiring SL can be arranged on the third buffer film BF3. Sensor wiring SL may not overlap with the light-emitting area EA. Sensor wiring SL can be formed as a single layer of molybdenum (Mo), titanium (Ti), copper (Cu), or aluminum (Al), or it can be formed as a stacked structure of aluminum and titanium (Ti / Al / Ti), a stacked structure of aluminum and ITO (ITO / Al / ITO), an APC alloy, or a stacked structure of APC alloy and ITO (ITO / APC / ITO).

[0262] A first sensor insulating film TINS1 can be arranged on the sensor wiring SL. The first sensor insulating film TINS1 can be formed using an inorganic film (e.g., a silicon nitride layer, a silicon oxynitride layer, a silicon oxide layer, a titanium oxide layer, or an aluminum oxide layer).

[0263] Sensor electrodes SE can be arranged on the first sensor insulating film TINS1. The sensor electrodes SE can be connected to the sensor wiring SL through the sensor contact SCNT. The sensor contact SCNT can be a region that penetrates the first sensor insulating film TINS1 and exposes the sensor wiring SL. The sensor electrodes SE can be formed using a transparent conductive material (TCO) that allows light to pass through, such as ITO or IZO.

[0264] A second sensor insulating film TINS2 may be disposed on the sensor electrode SE. The second sensor insulating film TINS2 may include at least one of an inorganic film and an organic film. The inorganic film may be a silicon nitride layer, a silicon oxynitride layer, a silicon oxide layer, a titanium oxide layer, or an aluminum oxide layer. The organic film may be an acrylic resin, an epoxy resin, a phenolic resin, a polyamide resin, or a polyimide resin.

[0265] Figure 21 It is shown Figure 6 This is another example of the layout diagram of sensor wiring, sensor electrodes, and sensor contacts. Figure 22 It shows along Figure 21 The I-I' section is a cross-sectional view of an example of a display panel.

[0266] Figure 21 and Figure 22 Implementation examples and Figure 19 and Figure 20 The difference in the embodiment is that the area of ​​the sensor contact portion SCNT that connects the sensor electrode SE and the sensor wiring SL is increased.

[0267] Figure 21and Figure 22 The lengths W21 of the sensor contact portion SCNT in the second direction (Y-axis direction) and W22 of the first direction (X-axis direction) can be respectively compared to Figure 19 and Figure 20 The sensor contact portion SCNT shown has a length W11 in the second direction (Y-axis direction) and a length W12 in the first direction (X-axis direction). Therefore, Figure 21 and Figure 22 The area of ​​the sensor contact portion SCNT shown can be greater than [the area of ​​the sensor contact portion SCNT shown]. Figure 19 and Figure 20 The area of ​​the sensor contact portion SCNT is shown. Increasing the area of ​​the sensor contact portion SCNT can reduce the contact resistance between the sensor electrode SE and the sensor wiring SL.

[0268] Since the longer the sensor wiring SL, the higher its resistance, the sensor contact portion SCNT of the sensor electrode SE connected to the relatively long sensor wiring SL can be formed with a larger area, while the sensor contact portion SCNT of the sensor electrode SE connected to the relatively short sensor wiring SL can be formed with a smaller area. This reduces the resistance difference between the sensor wirings SL.

[0269] Figure 23 It shows along Figure 21 Another example of a cross-sectional view of a display panel, taken from I-I'.

[0270] Figure 23 Implementation examples and Figure 22 The difference in the embodiment is that the electrode CAPE is arranged on the sensor electrode SE at the sensor contact SCNT.

[0271] Reference Figure 23 The capping electrode (CAPE) can be arranged on the sensor electrode (SE) in a manner that fills the sensor contact portion (SCNT). The area of ​​the capping electrode (CAPE) can be larger than the area of ​​the sensor contact portion (SCNT). The capping electrode (CAPE) does not need to overlap with the light-emitting area (EA). The capping electrode (CAPE) can include molybdenum (Mo), titanium (Ti), copper (Cu), or aluminum (Al).

[0272] Furthermore, when a portion of the sensor electrode SE disposed on the sensor wiring SL is removed from the sensor contact portion SCNT, the cover electrode CAPE can be directly connected to the sensor wiring SL. In this case, if the cover electrode CAPE comprises a low-resistivity material, the contact resistance between the sensor wiring SL and the sensor electrode SE can be reduced.

[0273] like Figure 23As shown, when the cover electrode CAPE is arranged on the sensor contact portion SCNT, the contact resistance between the sensor electrode SE and the sensor wiring SL can be reduced.

[0274] Furthermore, since the resistance of the sensor wiring SL is higher the longer it is, a cover electrode CAPE can be arranged at the sensor contact portion SCNT of the sensor electrode SE connected to the relatively long sensor wiring SL, while no cover electrode CAPE is arranged at the sensor contact portion SCNT of the sensor electrode SE connected to the relatively short sensor wiring SL. In this case, the resistance difference between the sensor wirings SL can be reduced.

[0275] Figure 24 It is shown Figure 6 This is another example of the layout diagram of sensor wiring, sensor electrodes, and sensor contacts.

[0276] Figure 24 Implementation examples and Figure 19 The difference in the embodiment is that the sensor contact portion SCNT is tilted at a first angle θ1 relative to the first direction (X-axis direction). The first angle θ1 can be an acute angle.

[0277] Figure 25 This is a layout diagram showing an example of sensor electrodes arranged in a row and sensor wiring connected thereto. Figures 26a to 26c It is along Figure 25 A cross-sectional view of an example of the display panel, taken from sections II-II', III-III', and IV-IV'.

[0278] For ease of explanation, Figure 25 The example only shows the first sensor electrode SE1, the second sensor electrode SE2, and the third sensor electrode SE3 arranged adjacent to each other in the second direction (Y-axis direction).

[0279] Reference Figure 25 and Figures 26a to 26c The first sensor electrode SE1 can be arranged at the top among the first sensor electrode SE1, the second sensor electrode SE2, and the third sensor electrode SE3, and the third sensor electrode SE3 can be arranged at the bottom among the first sensor electrode SE1, the second sensor electrode SE2, and the third sensor electrode SE3.

[0280] The first sensor electrode SE1 can be connected to the first sensor wiring SL1 via the first sensor contact SCNT1. The second sensor electrode SE2 can be connected to the second sensor wiring SL2 via the second sensor contact SCNT2. The third sensor electrode SE3 can be connected to the third sensor wiring SL3 via the third sensor contact SCNT3.

[0281] The first sensor wiring SL1, the second sensor wiring SL2, and the third sensor wiring SL3 can extend along the second direction (Y-axis direction). The first sensor wiring SL1, the second sensor wiring SL2, and the third sensor wiring SL3 can be connected to the pad TP arranged below the third sensor electrode SE3. Therefore, the length of the third sensor wiring SL3, which is arranged at the bottom among the first sensor electrodes SE1, the second sensor electrode SE2, and the third sensor electrode SE3, can be the shortest, and the length of the first sensor wiring SL1, which is arranged at the top among the first sensor electrodes SE1, the second sensor electrode SE2, and the third sensor electrode SE3, can be the longest.

[0282] Since the first sensor wiring SL1 is the longest and the third sensor wiring SL3 is the shortest, the resistance of the first sensor wiring SL1 can be the largest, and the resistance of the third sensor wiring SL3 can be the smallest. Figures 26a to 26c As shown, the width W1 of the first sensor wiring SL1 can be greater than the width W2 of the second sensor wiring SL2, and the width W2 of the second sensor wiring SL2 can be greater than the width W3 of the third sensor wiring SL3. In this case, the resistance difference between the first sensor wiring SL1, the second sensor wiring SL2, and the third sensor wiring SL3 can be reduced.

[0283] Figure 27 This is a layout diagram showing an example of sensor electrodes arranged in a row and sensor wiring connected thereto.

[0284] Figure 27 Implementation examples and Figure 25 The difference in the embodiments is that the width of the first sensor wiring SL1 and the width of the second sensor wiring SL2 gradually increase from the bottom to the top.

[0285] Reference Figure 27 The width of the overlap between the first sensor electrode SE1 and the third sensor electrode SE3 in the third direction (Z-axis direction) can be smaller than the width of the overlap between the first sensor electrode SE1 and the second sensor electrode SE2 in the third direction (Z-axis direction). Similarly, the width of the overlap between the first sensor electrode SE1 and the second sensor electrode SE2 in the third direction (Z-axis direction) can be smaller than the width of the overlap between the first sensor electrode SE1 and the first sensor electrode SE1 in the third direction (Z-axis direction).

[0286] The width of the overlap between the second sensor electrode SE2 and the third sensor electrode SE3 in the third direction (Z-axis direction) can be smaller than the width of the overlap between the second sensor electrode SE2 and the second sensor electrode SE2 in the third direction (Z-axis direction).

[0287] The overlap widths of the first sensor electrode SE1 with the third sensor electrode SE3 in the third direction (Z-axis direction), the overlap widths of the second sensor electrode SE2 with the third sensor electrode SE3 in the third direction (Z-axis direction), and the overlap widths of the third sensor electrode SE3 with the third sensor electrode SE3 in the third direction (Z-axis direction) can be substantially the same. The overlap widths of the first sensor electrode SE1 with the second sensor electrode SE2 in the third direction (Z-axis direction) and the overlap widths of the second sensor electrode SE2 with the second sensor electrode SE2 in the third direction (Z-axis direction) can also be substantially the same.

[0288] like Figure 27 As shown, when the width of the first sensor wiring SL1 and the width of the second sensor wiring SL2 gradually increase from the bottom to the top, the resistance difference between the first sensor wiring SL1, the second sensor wiring SL2 and the third sensor wiring SL3 can be reduced.

[0289] Figure 28 This is another example of a layout diagram showing sensor electrodes arranged in a row and sensor wiring connected thereto.

[0290] Figure 28 Implementation examples and Figure 25 The difference in the embodiments is that the second sensor wiring SL2 and the third sensor wiring SL3 have a curved shape including multiple bends.

[0291] Reference Figure 28 The second sensor wiring SL2 may have a curved shape including multiple bends between the second sensor electrode SE2 and the third sensor electrode SE3. The third sensor wiring SL3 may have a curved shape including multiple bends on the underside of the third sensor electrode SE3. For example, the second sensor wiring SL2 and the third sensor wiring SL3 may extend in one direction and then bend in another direction intersecting that direction, and then extend in the opposite direction of that direction and bend in another direction. The second sensor wiring SL2 may also have a curved shape including multiple bends on the underside of the third sensor electrode SE3.

[0292] like Figure 28 As shown, when the second sensor wiring SL2 and the third sensor wiring SL3 have a curved shape including multiple bends, the resistance difference between the first sensor wiring SL1, the second sensor wiring SL2, and the third sensor wiring SL3 can be reduced.

[0293] Figure 29 This is a layout diagram showing the sensor electrode layer of a display device according to an embodiment.

[0294] Figure 29 Implementation examples and Figure 6 The difference in the embodiment is that it includes multiple sub-grounding wires SGL connected to the second grounding wire GRL2.

[0295] Reference Figure 29 Multiple sub-grounding wires SGL can extend along the second direction (Y-axis direction). Multiple sub-grounding wires SGL can be connected to the second grounding wire GRL2 in the area TPA around the sensor, but are not limited to this. Multiple sub-grounding wires SGL can also be electrically floated without being connected to the second grounding wire GRL2.

[0296] Multiple sub-grounding wires SGL can be arranged parallel to the sensor wires SL in a second direction (Y-axis direction). Multiple sub-grounding wires SGL can be electrically isolated from the sensor wires SL. Multiple sub-grounding wires SGL can be arranged separately from the sensor wires SL. Each of the multiple sub-grounding wires SGL can overlap with at least one sensor electrode SE.

[0297] like Figure 29 As shown, this can prevent the area without sensor wiring SL from being identified by the user due to the difference in the number of sensor wiring SLs between the area without sensor wiring SL and the area with sensor wiring SL, thus preventing a decrease in image quality.

[0298] Figure 30 This is a layout diagram showing the sensor electrode layer of a display device according to yet another embodiment.

[0299] Figure 30 Implementation examples and Figure 6 The difference in the embodiment is that the wireless signal connection part RFC is arranged on the display panel 300.

[0300] Reference Figure 30 The wireless signal connection unit (RFC) can be arranged adjacent to the sensor pad area (SPA). For example, the RFC can be arranged above the sensor pad area (SPA). However, the arrangement of the RFC is not limited to this; it can be arranged adjacent to the sensor area (TSA). Alternatively, the RFC can be arranged throughout the entire space between the sensor pad area (SPA) and the sensor area (TSA). Or, the RFC can also be arranged within the sensor area (TSA).

[0301] The wireless signal connection unit RFC may include wireless signal wiring RFL. The wireless signal wiring RFL can be connected one-to-one to the sensor pad TP of the sensor pad area SPA. Therefore, the wireless signal wiring RFL can be electrically connected to the antenna drive circuit 340 of the display circuit board 310.

[0302] Figure 31 It is shown Figure 30 A layout diagram of an example of a wireless signal connection unit. Figure 32 It shows along Figure 31 A cross-sectional view of an example of a display panel, taken at V-V'.

[0303] Reference Figure 31 and Figure 32 The wireless signal wiring RFL1-RFLn and the sensor wiring SL1-SLn can extend along a second direction (Y-axis direction). The wireless signal wiring RFL1-RFLn and the sensor wiring SL1-SLn can be arranged alternately in a first direction (X-axis direction). Sensor wiring can be arranged between adjacent wireless signal wiring in the first direction (X-axis direction), and wireless signal wiring can be arranged between adjacent sensor wiring in the first direction (X-axis direction).

[0304] Since the wireless signal wiring RFL1~RFLn and the sensor wiring SL1~SLn are arranged parallel to each other, therefore... Figure 32 As shown, coupling capacitors Crf1 to Crfn corresponding to the edge capacitance can be formed between the wireless signal wiring RFL1 to RFLn and the sensor wiring SL1 to SLn.

[0305] For example, such as Figure 31 As shown, a first coupling capacitor Crf1 can be formed between the first wireless signal wiring RFL1 and the first sensor wiring SL1, and a second coupling capacitor Crf2 can be formed between the second wireless signal wiring RFL2 and the second sensor wiring SL2. In this case, the distance between the first wireless signal wiring RFL1 and the first sensor wiring SL1 can be smaller than the distance between the first wireless signal wiring RFL1 and the second sensor wiring SL2.

[0306] Furthermore, an (n-1)th coupling capacitor Crfn-1 can be formed between the (n-1)th wireless signal wiring RFLn-1 and the (n-1)th sensor wiring SLn-1, and an nth coupling capacitor Crfn can be formed between the nth wireless signal wiring RFLn and the nth sensor wiring SLn. In this case, the distance between the (n-1)th wireless signal wiring RFLn-1 and the (n-1)th sensor wiring SLn-1 can be less than the distance between the (n-1)th wireless signal wiring RFLn-1 and the nth sensor wiring SLn.

[0307] The capacitance of the first coupling capacitor Crf1 can be proportional to the parallel lengths of the first sensor wiring SL1 and the first wireless signal wiring RFL1. The larger the capacitance of the first coupling capacitor Crf1, the greater the signal coupling between the first sensor wiring SL1 and the first wireless signal wiring RFL1 caused by the first coupling capacitor Crf1. Therefore, the parallel lengths of the first sensor wiring SL1 and the first wireless signal wiring RFL1 can be designed taking into account the capacitance of the first coupling capacitor Crf1.

[0308] The first sensor wiring SL1 and the first wireless signal wiring RFL1 can be arranged on the same layer and formed using the same material. For example, the sensor wirings SL1 to SLn can be arranged as follows: Figure 20 As shown, in the sensor region, TSA is arranged on the third buffer membrane BF3; conversely, it can be arranged as follows: Figure 32 As shown, the sensor pad region SPA and the wireless signal connection portion RCF in the sensor surrounding area TPA can be arranged on the gate insulating film 130. In this case, the first sensor wiring SL1 and the first wireless signal wiring RFL1 can be arranged as follows: Figure 32 As shown, it is arranged on the gate insulating film 130 and can be utilized with Figure 20 The gate electrode G of the thin-film transistor ST shown is formed of the same material. Alternatively, the first sensor wiring SL1 and the first wireless signal wiring RFL1 can be arranged on the first interlayer insulating film 141, and utilize the same material as... Figure 20 The capacitor shown has one electrode CE made of the same material. Alternatively, the first sensor wiring SL1 and the first wireless signal wiring RFL1 can be arranged on the second buffer film BF2, and utilize the same material as... Figure 20 The active layer ACT of the thin-film transistor ST shown is formed of the same material. Alternatively, the first sensor wiring SL1 and the first wireless signal wiring RFL1 can be arranged on the first buffer film BF1, and utilize the same material as... Figure 20 The light-blocking layer BML shown is formed of the same material.

[0309] like Figure 31 and Figure 32 As shown, since the wireless signal wiring RFL1~RFLn and the sensor wiring SL1~SLn are arranged parallel to each other, therefore... Figure 32 As shown, coupling capacitors Crf1 to Crfn, corresponding to the edge capacitance, can be formed between the wireless signal wirings RFL1 to RFLn and the sensor wirings SL1 to SLn. Therefore, the signal from the sensor wirings SL1 to SLn can be coupled to the wireless signal wirings RFL1 to RFLn through the coupling capacitors Crf1 to Crfn. Furthermore, the signal from the wireless signal wirings RFL1 to RFLn can be coupled to the sensor wirings SL1 to SLn through the coupling capacitors Crf1 to Crfn.

[0310] Figure 33 It is shown Figure 30 A layout diagram of an example of a wireless signal connection unit. Figure 34 It shows along Figure 33 The VI-VI' section view is a cross-sectional view of an example of the display panel.

[0311] Figure 33 and Figure 34 Implementation examples and Figure 31 and Figure 32 The difference in the embodiments is that the wireless signal wiring RFL1~RFLn and the sensor wiring SL1~SLn overlap in the third direction (Z-axis direction) to form coupling capacitors Crf1~Crfn.

[0312] Reference Figure 33 and Figure 34 Because the wireless signal wiring RFL1~RFLn overlaps with the sensor wiring SL1~SLn in the third direction (Z-axis direction), therefore... Figure 34 As shown, coupling capacitors Crf1 to Crfn can be formed between the wireless signal wiring RFL1 to RFLn and the sensor wiring SL1 to SLn.

[0313] For example, such as Figure 33 As shown, a first coupling capacitor Crf1 can be formed between the first wireless signal wiring RFL1 and the first sensor wiring SL1, and a second coupling capacitor Crf2 can be formed between the second wireless signal wiring RFL2 and the second sensor wiring SL2. Furthermore, an (n-1)th coupling capacitor Crfn-1 can be formed between the (n-1)th wireless signal wiring RFLn-1 and the (n-1)th sensor wiring SLn-1, and an nth coupling capacitor Crfn can be formed between the nth wireless signal wiring RFLn and the nth sensor wiring SLn.

[0314] The capacitance of the first coupling capacitor Crf1 is proportional to the overlap area of ​​the first sensor wiring SL1 and the first wireless signal wiring RFL1. The larger the capacitance of the first coupling capacitor Crf1, the greater the signal coupling between the first sensor wiring SL1 and the first wireless signal wiring RFL1 caused by the first coupling capacitor Crf1. Therefore, the overlap area of ​​the first sensor wiring SL1 and the first wireless signal wiring RFL1 can be designed taking into account the capacitance of the first coupling capacitor Crf1.

[0315] The first sensor wiring SL1 and the first wireless signal wiring RFL1 can be arranged on different layers and formed using different materials. For example, the sensor wirings SL1 to SLn can be arranged as follows: Figure 20As shown, in the sensor region, TSA is arranged on the third buffer membrane BF3; conversely, it can be arranged as follows: Figure 32 As shown, the sensor pad region SPA and the wireless signal connection portion RCF in the sensor surrounding area TPA can be arranged on the gate insulating film 130. In this case, the first sensor wiring SL1 can utilize... Figure 20 The thin-film transistor ST shown is formed of the same material as its gate electrode G, and the first wireless signal wiring RFL1 can be formed as follows: Figure 34 As shown, it is arranged on the first interlayer insulating film 141, and utilizes with Figure 20 The capacitor shown has one electrode CE made of the same material. Alternatively, the first wireless signal wiring RFL1 can be arranged on the second buffer film BF2, and utilize the same material as... Figure 20 The active layer ACT of the thin-film transistor ST shown is formed of the same material. Alternatively, the first wireless signal wiring RFL1 can be arranged on the first buffer film BF1 and utilize the same material as... Figure 20 The light-blocking layer BML shown is formed of the same material.

[0316] like Figure 33 and Figure 34 As shown, since the wireless signal wiring RFL1~RFLn overlaps with the sensor wiring SL1~SLn in the third direction (Z-axis direction), therefore... Figure 34 As shown, coupling capacitors Crf1 to Crfn can be formed between the wireless signal wirings RFL1 to RFLn and the sensor wirings SL1 to SLn. Therefore, the signal from the sensor wirings SL1 to SLn can be coupled to the wireless signal wirings RFL1 to RFLn through the coupling capacitors Crf1 to Crfn. Furthermore, the signal from the wireless signal wirings RFL1 to RFLn can be coupled to the sensor wirings SL1 to SLn through the coupling capacitors Crf1 to Crfn.

[0317] Figure 35 This is a layout diagram showing the sensor electrode layer of a display device according to yet another embodiment.

[0318] Figure 35 Implementation examples and Figure 30 The difference in the embodiment is that the sensor wiring SL does not overlap with any of the sensor electrodes SE in the third direction (Z-axis direction).

[0319] Reference Figure 35 The sensor wiring SL can be arranged on one side of the sensor electrode SE. The sensor wiring SL and the sensor electrode SE can be arranged in the same layer and can be formed using the same material. For example, the sensor wiring SL and the sensor electrode SE can be arranged in... Figure 20 The third buffer membrane BF3 is shown.

[0320] Figure 36 This is a layout diagram showing the sensor electrode layer of a display device according to yet another embodiment.

[0321] Figure 36 Implementation examples and Figure 35 The difference in the embodiment is that the sensor wiring SL is connected to the first sensor pad TP1 of the first sensor pad area SPA1 arranged on one side in the sensor pad areas SPA1 and SPA2, and the wireless signal wiring RFL of the wireless signal connection part RFC is connected to the second sensor pad TP2 of the second sensor pad area SPA2 arranged on the other side in the sensor pad areas SPA1 and SPA2.

[0322] Reference Figure 36 The sensor wiring SL can be connected to the first sensor pad TP1 of the first sensor pad area SPA1 located on the left side of the sensor pad areas SPA1 and SPA2. The first sensor pad TP1 of the first sensor pad area SPA1 can be electrically connected to the first bump of the first bump area BP1 of the display circuit board 310 through an anisotropic conductive film. Accordingly, the sensor wiring SL can be electrically connected to the touch driving circuit 330 of the display circuit board 310.

[0323] The wireless signal wiring RFL of the wireless signal connection unit RFC can be connected to the second sensor pad TP2 of the second sensor pad area SPA2 located on the right side of the sensor pad areas SPA1 and SPA2. The second sensor pad TP2 of the second sensor pad area SPA2 can be electrically connected to the second bump of the second bump area BP2 of the antenna circuit board 360 through an anisotropic conductive film. Accordingly, the wireless signal wiring RFL can be electrically connected to the antenna drive circuit 340 of the antenna circuit board 360.

[0324] like Figure 36 As shown, by placing a first sensor pad region SPA1, including a first sensor pad TP1 connected to sensor wiring SL, on one side of sensor pad regions SPA1 and SPA2, and placing a second sensor pad region SPA2, including a second sensor pad TP2 connected to wireless signal wiring RFL, on the other side of sensor pad regions SPA1 and SPA2, the first sensor pad region SPA1 and the second sensor pad region SPA2 can be connected to different circuit boards. Therefore, the touch driving circuit 330 and the antenna driving circuit 340 can be arranged on different circuit boards.

[0325] Figure 37 This is a layout diagram showing the sensor electrode layer of a display device according to yet another embodiment.

[0326] Figure 37 Implementation examples and Figure 6The difference in the embodiment is that separate antenna electrodes ASE1 and ASE2 are arranged between the sensor electrodes SE.

[0327] Reference Figure 37 The first antenna electrode ASE1 can be arranged between four sensor electrodes SE that are adjacent to each other in the first direction (X-axis direction) and the second direction (Y-axis direction). The first antenna electrode ASE1 can have a cross-shaped planar shape. The first antenna electrode ASE1 can be connected to the first wireless signal wiring RFL1.

[0328] The second antenna electrode ASE2 can extend along a second direction (Y-axis direction). The second antenna electrode ASE2 can be arranged between the sensor electrode SE arranged in the k-th column (k is a positive integer) and the sensor electrode SE arranged in the (k+1)-th column. The second antenna electrode ASE2 can have a planar shape, such as a rod. The second antenna electrode ASE2 can be connected to the second wireless signal wiring RFL2.

[0329] The first wireless signal wiring RFL1 and the second wireless signal wiring RFL2 can be connected to the second sensor pad TP2 of the second sensor pad region SPA2 arranged on the upper side of the display panel 300. The second sensor pad TP2 of the second sensor pad region SPA2 can be electrically connected to the second bump of the second bump region BP2 of the antenna circuit board 360 through an anisotropic conductive film. Accordingly, the wireless signal wiring RFL can be electrically connected to the antenna driving circuit 340 of the antenna circuit board 360.

[0330] like Figure 37 As shown, when separate antenna electrodes ASE1 and ASE2 are arranged between the sensor electrodes SE, the wireless signal connection section RFC can be omitted.

[0331] Furthermore, the wireless signal wirings RFL1 and RFL2 connected to the antenna electrodes ASE1 and ASE2 can be connected to the second sensor pad TP2 of the second sensor pad area SPA2 arranged on the upper side of the display panel 300. The second sensor pad TP2 can be electrically connected to the second bump of the second bump area BP2 of the antenna circuit board 360 on which the antenna driving circuit 340 is arranged. Therefore, the touch driving circuit 330 and the antenna driving circuit 340 can be arranged on different circuit boards.

[0332] Figure 38 This is a layout diagram showing the sensor electrode layer of a display device according to yet another embodiment.

[0333] Figure 38 Implementation examples and Figure 35 The difference in the embodiments is that the area of ​​the sensor electrode SE decreases from the upper side to the lower side of the sensor region TSA.

[0334] refer to Figure 38 The number of sensor wirings SL increases from the top to the bottom of the sensor region TSA. Therefore, by making the area of ​​the sensor electrode SE decrease from the top to the bottom of the sensor region TSA, sufficient space can be ensured for arranging the sensor wirings SL. Furthermore, since the resistance of the sensor wiring SL connected to the sensor electrode SE arranged on the top of the sensor region TSA is greater than the resistance of the sensor wiring SL connected to the sensor electrode SE arranged on the bottom of the sensor region TSA, the area of ​​the sensor electrode SE can increase from the bottom to the top of the sensor region TSA.

[0335] Figure 39 This is a layout diagram showing the sensor electrode layer of a display device according to yet another embodiment.

[0336] Figure 39 Implementation examples and Figure 38 The difference in the embodiments is that the area of ​​each of the sensor electrodes SE in the sensor region TSA is substantially the same, and the sensor electrodes SE adjacent to the upper side of the sensor region TSA include a protective pattern PPE.

[0337] Reference Figure 39 When considering the resistance of the sensor wiring SL, the area of ​​the sensor electrode SE preferably increases from the lower side to the upper side of the sensor region TSA. However, if the area of ​​the sensor electrode SE is larger than the area required for 5G communication, it may be difficult to perform normal functions as an antenna. Therefore, instead of making the area of ​​the sensor electrode SE increase from the lower side to the upper side of the sensor region TSA, a protective pattern PPE can be included on at least one side of the sensor electrode SE.

[0338] exist Figure 39 The example illustrates a scenario where the protective pattern PPE is arranged on both sides of the sensor electrode SE, but it is not limited to this. Furthermore, in... Figure 39 The example illustrates that the protective pattern PPE is formed in the shape of a "┐" that is bent at least once, but it is not limited to this.

[0339] The protective pattern PPE can be electrically floated or connected to the second grounding wiring GRL2 to receive the grounding voltage. In this case, since the static electricity applied to the sensor electrode SE can be discharged to the protective pattern PPE, the sensor electrode SE can be protected from the effects of static electricity.

[0340] Figure 40 This is a layout diagram showing the sensor electrode layer of a display device according to yet another embodiment.

[0341] Figure 40 Implementation examples and Figure 6The difference in the embodiment is that the display device 10 includes a switching circuit section SWC instead of a wireless signal connection section RFC.

[0342] exist Figure 40 The example illustrates a scenario where the switching circuit section (SWC) is arranged on the display circuit board 310, but it is not limited to this. The switching circuit section (SWC) can be arranged as follows: Figure 30 As shown, it is arranged on the display panel 300. In this case, the switching circuit section SWC can be arranged in the space between the sensor pad area SPA and the sensor area TSA.

[0343] Figure 41a It is shown Figure 40 A circuit diagram of an example of a switching circuit section.

[0344] Figure 41a Implementation examples and Figure 7 The difference in the embodiment is that a switching circuit section SWC is arranged instead of a wireless signal connection section RFC.

[0345] Reference Figure 41a The display circuit board 310 may include sensor circuit wiring SLP1 to SLPn, wireless signal wiring RFL1 to RFLn, sensor connection wiring SLC1 to SLCn, and switching elements SW1 to SWn of the switching circuit section SWC.

[0346] One end of each of the sensor circuit wirings SLP1 to SLPn can be connected to Figure 6 One end of the bump in the bump area BP is connected to one of the bumps, and the other end is connected to one of the switching elements SW1 to SWn. Since the sensor circuit wiring SLP1 to SLPn is connected to the pad TP of the display panel 300 through the bumps, it can be electrically connected to the sensor electrode SE and the sensor wiring SL of the display panel 300.

[0347] One end of each of the wireless signal wirings RFL1 to RFLn can be connected to one of the switching elements SW1 to SWn, and the other end can be connected to the antenna drive circuit 340.

[0348] One end of each of the sensor connection wires SLC1 to SLCn can be connected to one of the switching elements SW1 to SWn, and the other end can be connected to the touch driving circuit 330.

[0349] Each of the switching elements SW1 to SWn can connect one of the sensor circuit wirings SLP1 to SLPn to one of the sensor connection wirings SLC1 to SLCn, or to one of the wireless signal wirings RFL1 to RFLn, according to the switch control signal SCC. The switch control signal SCC can be output from the touch driving circuit 330. The switch control signal SCC can be output from the antenna driving circuit 340.

[0350] For example, the first switching element SW1 can connect the first sensor circuit wiring SLP1 to one of the first sensor connection wiring SLC1 and the first wireless signal wiring RFL1 according to the switching control signal SCC. The second switching element SW2 can connect the second sensor circuit wiring SLP2 to one of the second sensor connection wiring SLC2 and the second wireless signal wiring RFL2 according to the switching control signal SCC. The (n-1)th switching element SWn-1 can connect the (n-1)th sensor circuit wiring SLPn-1 to one of the (n-1)th sensor connection wiring SLCn-1 and the (n-1)th wireless signal wiring RFLn-1 according to the switching control signal SCC. The nth switching element SWn can connect the nth sensor circuit wiring SLPn to one of the nth sensor connection wiring SLCn and the nth wireless signal wiring RFLn according to the switching control signal SCC.

[0351] like Figure 41a As shown, when the sensor circuit wirings SLP1~SLPn are connected to the sensor connection wirings SLC1~SLCn via switching elements SW1~SWn, the sensor electrode SE can be electrically connected to the touch driving circuit 330. Furthermore, when the sensor circuit wirings SLP1~SLPn are connected to the wireless signal wirings RFL1~RFLn via switching elements SW1~SWn, the sensor electrode SE can be electrically connected to the antenna driving circuit 340. Therefore, the touch driving circuit 330 and the antenna driving circuit 340 can achieve frequency division duplex.

[0352] Figure 41b It is shown Figure 40 A circuit diagram of an example of a switching circuit section.

[0353] Figure 41b Implementation examples and Figure 41a The difference in the embodiments is that each of the switching elements SW1 to SWn connects one of the sensor circuit wirings SLP1 to SLPn to one of the sensor connection wirings SLC1 to SLCn, one of the wireless signal wirings RFL1 to RFLn, or one of the disconnect terminals STER according to the switching control signal SCC.

[0354] likeFigure 41b As shown, when the sensor circuit wirings SLP1~SLPn are connected to the sensor connection wirings SLC1~SLCn via switching elements SW1~SWn, the sensor electrode SE can be electrically connected to the touch driving circuit 330. Furthermore, when the sensor circuit wirings SLP1~SLPn are connected to the wireless signal wirings RFL1~RFLn via switching elements SW1~SWn, the sensor electrode SE can be electrically connected to the antenna driving circuit 340. Moreover, when the sensor circuit wirings SLP1~SLPn are connected to the disconnect terminal STER via switching elements SW1~SWn, the sensor circuit wirings SLP1~SLPn, the wireless signal wirings RFL1~RFLn, and the sensor connection wirings SLC1~SLCn can be electrically disconnected from each other.

[0355] Figure 42 This is a cross-sectional view showing a display device according to yet another embodiment. Figure 43 It is shown Figure 42 This is a layout diagram of an example of sensor wiring, sensor electrodes, and sensor contacts. Figure 44 It shows along Figure 43 A cross-sectional view of an example of the display panel captured by IX-IX'.

[0356] Reference Figures 42 to 44 The sensor electrode SE1 and sensor wiring SL1 can have a grid structure or a mesh structure on the plane. The sensor electrode SE1 and sensor wiring SL1 can be non-overlapping with the light-emitting area EA, thus preventing the light emitted from the light-emitting area EA from being covered by the sensor electrode SE1 and thus reducing the brightness of the light.

[0357] The sensor electrode SE1 and sensor wiring SL1 can extend along the fourth direction DR4 and the fifth direction DR5. The fourth direction DR4 can be tilted at an angle of approximately 45° relative to the first direction (X-axis direction), but is not limited to this. The fifth direction DR5 can be tilted at an angle of approximately 45° relative to the second direction (Y-axis direction), but is not limited to this.

[0358] Sensor electrode SE1 can be connected to sensor wiring SL1 via sensor contact SCNT1. Sensor wiring SL1 can be arranged on the third buffer film BF3, and sensor electrode SE1 can be arranged on the first sensor insulating film TINS1. Sensor contact SCNT1 can be a hole that penetrates the first sensor insulating film TINS1 and exposes sensor wiring SL1. Each of sensor electrode SE1 and sensor wiring SL1 can be formed as a single layer of molybdenum (Mo), titanium (Ti), copper (Cu), or aluminum (Al), or can be formed as a laminated structure of aluminum and titanium (Ti / Al / Ti), a laminated structure of aluminum and ITO (ITO / Al / ITO), an APC alloy, or a laminated structure of APC alloy and ITO (ITO / APC / ITO).

[0359] The emitting region EA can include a first emitting region RE, a second emitting region GE, and a third emitting region BE. Each of the first emitting regions RE can be an area that emits light of a first color, each of the second emitting regions GE can be an area that emits light of a second color, and each of the third emitting regions BE can be an area that emits light of a third color. For example, the first color can be red, the second color can be green, and the third color can be blue, but it is not limited to these.

[0360] Examples are given where each of the first luminous region RE, the second luminous region GE, and the third luminous region BE has a rhomboid or rectangular planar shape, but these are not limited to. Each of the first luminous region RE, the second luminous region GE, and the third luminous region BE can have a planar shape other than a quadrilateral, such as a polygon, a circle, or an ellipse. Furthermore, examples are given where the third luminous region BE has the largest area and the second luminous region GE has the smallest area, but these are not limited to.

[0361] A first luminous region RE, two second luminous regions GE, and a third luminous region BE can be defined as a luminous group EG used to represent white tones. That is, white tones can be represented by a combination of light emitted from a first luminous region RE, light emitted from the two second luminous regions GE, and light emitted from a third luminous region BE.

[0362] The second luminous region GE can be arranged in odd-numbered rows. The second luminous regions GE can be neatly arranged along the first direction (X-axis direction) in each of the odd-numbered rows. In each of the odd-numbered rows, among the adjacent second luminous regions GE in the first direction (X-axis direction), one can have a long side of the fourth direction DR4 and a short side of the fifth direction DR5; conversely, the other can have a long side of the fifth direction DR5 and a short side of the fourth direction DR4. The fourth direction DR4 can be the direction between the first direction (X-axis direction) and the second direction (Y-axis direction), and the fifth direction DR5 is the direction that intersects with the fourth direction DR4.

[0363] The first luminous region RE and the third luminous region BE can be arranged in even-numbered rows. The first luminous region RE and the third luminous region BE can be arranged neatly along the first direction (X-axis direction) in each even-numbered row. The first luminous region RE and the third luminous region BE can be arranged alternately in each even-numbered row.

[0369] The first side portion SS1 of the display panel 300 can extend from the first side of the front portion PS. For example, as Figure 45 As shown, the first side portion SS1 can extend from the left side of the front portion PS. The first side portion SS1 can bend at a first curvature line. The first curvature line can be the boundary between the front portion PS and the first side portion SS1. The first side portion SS1 can be the left side face of the display panel 300.

[0370] The second side portion SS2 of the display panel 300 can extend from the second side of the front portion PS.

[0375] The third corner portion CS3 of the display panel 300 can extend from the third corner where the second and fourth sides of the front part PS meet. The third corner portion CS3 can be arranged between the second side part SS2 and the fourth side part SS4.

[0379] Figure 46 and Figure 47 This is a perspective view showing a display device according to yet another embodiment. Figure 46 and Figure 47 The example illustrates that the display device 10 is a foldable display device that folds in a first direction (X-axis direction).

[0380] Reference Figure 46 and Figure 47 The display device 10 can be maintained in both a folded and unfolded state. The display device 10 can be folded in an in-folding manner with the front side facing inwards. When the display device 10 is bent or folded in an in-folding manner, the front sides of the display device 10 can be arranged to face each other. Alternatively, the display device 10 can be folded in an out-folding manner with the front side facing outwards. When the display device 10 is bent or folded in an out-folding manner, the back sides of the display device 10 can be arranged to face each other.

[0381] The first non-foldable region NFA1 can be located on one side of the foldable region FDA, such as the right side. The second non-foldable region NFA2 can be located on the other side of the foldable region FDA, such as the left side.

[0382] The first fold line FOL1 and the second fold line FOL2 can extend along the second direction (Y-axis direction), and the display device 10 is folded along the first direction (X-axis direction). Accordingly, the length of the display device 10 in the first direction (X-axis direction) can be reduced to about half, so that the user can easily carry the display device 10.

[0383] Furthermore, the extension directions of the first fold line FOL1 and the second fold line FOL2 are not limited to the second direction (Y-axis direction). For example, the first fold line FOL1 and the second fold line FOL2 can extend along the first direction (X-axis direction), and the display device 10 can be folded along the second direction (Y-axis direction). In this case, the length of the display device 10 in the second direction (Y-axis direction) can be reduced to approximately half. Alternatively, the first fold line FOL1 and the second fold line FOL2 can extend along a diagonal direction of the display device 10 between the first direction (X-axis direction) and the second direction (Y-axis direction). In this case, the display device 10 can be folded into a triangular shape.

[0384] When the first fold line FOL1 and the second fold line FOL2 extend along the second direction (Y-axis direction), the length of the folded region FDA in the first direction (X-axis direction) can be less than the length of the folded region FDA in the second direction (Y-axis direction). Furthermore, the length of the first non-folded region NFA1 in the first direction (X-axis direction) can be greater than the length of the folded region FDA in the first direction (X-axis direction). The length of the second non-folded region NFA2 in the first direction (X-axis direction) can be greater than the length of the folded region FDA in the first direction (X-axis direction).

[0385] The display device 10 may include a first display area DA1, a second display area DA2, a first non-display area NDA1, and a second non-display area NDA2. The first display area DA1 and the first non-display area NDA1 may be arranged on the upper surface of the display device 10. The first display area DA1 and the first non-display area NDA1 may overlap with the folding area FDA, the first non-folding area NFA1, and the second non-folding area NFA2. Therefore, when the display device 10 is unfolded, an image can be displayed on the upper surface of the folding area FDA, the first non-folding area NFA1, and the second non-folding area NFA2 of the display device 10.

[0386] The second display area DA2 and the second non-display area NDA2 can be arranged on the lower surface of the display device 10. The second display area DA2 and the second non-display area NDA2 can overlap with the second non-folding area NFA2. Therefore, when the display device 10 is folded, an image can be displayed on the lower surface of the second non-folding area NFA2 of the display device 10.

[0387] Figure 48 and Figure 49 This is a perspective view showing a display device according to yet another embodiment. Figure 48 and Figure 49 The example illustrates that the display device 10 is a foldable display device that folds in a second direction (Y-axis direction).

[0388] Reference Figure 48 and Figure 49 The display device 10 can be maintained in both a folded and unfolded state. The display device 10 can be folded in an in-folding manner with the front side facing inwards. When the display device 10 is bent or folded in an in-folding manner, the front sides of the display device 10 can be arranged to face each other. Alternatively, the display device 10 can be folded in an out-folding manner with the front side facing outwards. When the display device 10 is bent or folded in an out-folding manner, the back sides of the display device 10 can be arranged to face each other.

[0389] The display device 10 may include a foldable region FDA, a first non-foldable region NFA1, and a second non-foldable region NFA2. The foldable region FDA may be the area of ​​the display device 10 that is folded, and the first non-foldable region NFA1 and the second non-foldable region NFA2 are the areas of the display device 10 that are not folded.

[0390] The first non-folded region NFA1 can be arranged on one side of the folded region FDA, such as the lower side. The second non-folded region NFA2 can be arranged on the other side of the folded region FDA, such as the upper side. The folded region FDA can be a region that is curved at a predetermined curvature along the first fold line FOL1 and the second fold line FOL2. Therefore, the first fold line FOL1 can be the boundary between the folded region FDA and the first non-folded region NFA1, and the second fold line FOL2 can be the boundary between the folded region FDA and the second non-folded region NFA2.

[0391] like Figure 48 and Figure 49 As shown, the first fold line FOL1 and the second fold line FOL2 can extend along the first direction (X-axis direction), and the display device 10 is folded along the second direction (Y-axis direction). Accordingly, the length of the display device 10 in the second direction (Y-axis direction) can be reduced to about half, so that the user can easily carry the display device 10.

[0392] Furthermore, the extension directions of the first fold line FOL1 and the second fold line FOL2 are not limited to the first direction (X-axis direction). For example, the first fold line FOL1 and the second fold line FOL2 can extend along the second direction (Y-axis direction), and the display device 10 folds along the first direction (X-axis direction). In this case, the length of the display device 10 in the first direction (X-axis direction) can be reduced to approximately half. Alternatively, the first fold line FOL1 and the second fold line FOL2 can extend along a diagonal direction of the display device 10 between the first direction (X-axis direction) and the second direction (Y-axis direction). In this case, the display device 10 can be folded into a triangular shape.

[0393] like Figure 48 and Figure 49 As shown, when the first fold line FOL1 and the second fold line FOL2 extend along the first direction (X-axis direction), the length of the folded region FDA in the second direction (Y-axis direction) can be less than the length of the first direction (X-axis direction). Furthermore, the length of the first non-folded region NFA1 in the second direction (Y-axis direction) can be greater than the length of the folded region FDA in the second direction (Y-axis direction). The length of the second non-folded region NFA2 in the second direction (Y-axis direction) can be greater than the length of the folded region FDA in the second direction (Y-axis direction).

[0394] The first display area DA1 can be arranged on the upper surface of the display device 10. Figure 48 and Figure 49 The example illustrates a scenario where each of the first display area DA1 and the first non-display area NDA1 overlaps with the folded area FDA, the first non-folded area NFA1, and the second non-folded area NFA2; however, it is not limited to this. For example, each of the display area DA and the non-display area NDA may overlap with at least one of the folded area FDA, the first non-folded area NFA1, and the second non-folded area NFA2.

[0395] The second display area DA2 and the second non-display area NDA2 can be arranged on the lower surface of the display device 10. The second display area DA2 and the second non-display area NDA2 can overlap with the second non-folding area NFA2. Therefore, when the display device 10 is folded, an image can be displayed on the lower surface of the second non-folding area NFA2 of the display device 10.

Therefore, the embodiments described above should be understood in all respects as illustrative and not limiting.
