[0042] The invention will now be described more fully below with reference to the accompanying drawings, in which various embodiments are illustrated. However, the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided to make this disclosure exhaustive and thorough, and will fully convey the scope of the invention to those skilled in the art. Throughout the text, the same reference numerals refer to the same elements.

[0043] What will be understood is that when an element is referred to as being "on" another element, it can be directly on the other element, or there can be an intermediate element between the two. Conversely, when an element is referred to as being "directly" on another element, there is no intermediate element.

[0044] It will be understood that while the terms “first,” “second,” “third,” etc., may be used herein to describe various elements, components, regions, layers, and / or parts, these elements, components, regions, layers, and / or parts should not be limited by these terms. These terms are used only to distinguish one element, component, region, layer, or part from another. Therefore, “first element,” “first component,” “first region,” “first layer,” or “first part” discussed below may be referred to as a second element, second component, second region, second layer, or second part without departing from the teachings of this document.

[0045] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. The singular forms “a” and “the (described)” as used herein are intended to include the plural forms (including “at least one”) unless the context clearly indicates otherwise. “Or” means “and / or”. As used herein, the term “and / or” includes any and all combinations of one or more of the associated listed items. It will be further understood that the terms “comprising” and / or “including” as used in this specification indicate the presence of the stated features, areas, integrals, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, areas, integrals, steps, operations, elements, components, and / or groups thereof.

[0046] Furthermore, relative terms such as “below” or “bottom” and “above” or “top” may be used herein to describe the relationship between one element and another(s) as shown in the accompanying drawings. It will be understood that, in addition to the orientations shown in the drawings, relative terms are intended to also include different orientations of the device. For example, if a device in one of the drawings is flipped, an element described as being “below” the other element will be oriented to be “above” the other element. Thus, depending on the specific orientation of the drawing, the exemplary term “below” can encompass both “below” and “above” orientations. Similarly, if a device in one of the drawings is flipped, an element described as being “below” or “under” the other element will be oriented to be “above” the other element. Thus, the exemplary terms “below” and “under” can encompass both “above” and “below” orientations.

[0047] Unless otherwise specified, all terms used herein (including technical and scientific terms) shall have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure pertains. It will be further understood that terms defined, for example, in common dictionaries should be interpreted as having meanings consistent with their meanings in the relevant field and in the context of this disclosure, and shall not be interpreted in an idealized or overly formal sense unless expressly defined herein.

[0048] In this document, embodiments are described with reference to cross-sectional views, which are schematic illustrations of rationalized embodiments. Therefore, variations in the illustrated shapes can be expected due to, for example, manufacturing techniques and / or tolerances. Consequently, the embodiments described herein should not be construed as limited to the specific shapes of the regions illustrated herein, but will include deviations in shape due to, for example, manufacturing processes. For example, regions illustrated or described as flat may generally have rough and / or non-linear characteristics. Furthermore, illustrated sharp corners may be rounded. Therefore, the regions illustrated in the figures are substantially schematic, and their shapes are not intended to illustrate the precise shapes of the regions and are not intended to limit the scope of the claims.

[0049] In the following, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0050] Figure 1 The figure shows a plan view of a display device according to an embodiment; and Figure 2 The diagram shows Figure 1 A magnified view of the outer perimeter of the opening area of ​​the display device.

[0051] Reference Figure 1 and Figure 2 An embodiment of the display device 10 may include a display area DA, an opening area HA, an opening peripheral area HPA, and a peripheral area PA.

[0052] Multiple pixels can be arranged in a display area DA to display an image. The display area DA can be arranged on a plane defined by a first direction D1 and a second direction D2, and can have a rectangular shape when viewed from a plan view in a direction perpendicular to the first direction D1 and the second direction D2 or in the thickness direction of the display device 10. In an embodiment, as... Figure 1 As shown, the display area DA may have rounded corners, but the embodiments are not limited to this, and alternatively, the shape of the display area DA may be modified in various ways to one of a variety of shapes.

[0053] The peripheral region PA can surround the display region DA and is a non-display area within it where no image is displayed.

[0054] The opening region HA can be surrounded by the opening perimeter region HPA. The opening region HA is the area for mounting optical modules and allows light to pass through it. For example, in one embodiment, a circular hole through the substrate can be defined in the opening region HA, or a transparent window can be arranged in the opening region HA.

[0055] The aperture perimeter area (HPA) can surround the aperture area (HA) and can be surrounded by the display area (DA). The aperture perimeter area (HPA) is a non-display area, and signal lines, etc., can be arranged within the aperture perimeter area (HPA).

The loop antenna electrode 150 can extend along the peripheral region HPA and can have a C-shape to surround the opening region HA. A first wiring 152 can be connected to one end of the loop antenna electrode 150. A second wiring 154 can be connected to the opposite end of the loop antenna electrode 150. The first wiring 152 and the second wiring 154 can extend to the peripheral region PA by passing through the display region DA.

[0057] An external driver (not shown) may be arranged or provided in the peripheral area PA. In an embodiment, the driver may include a radio frequency integrated circuit (“RFIC”) configured to feed power to the loop antenna electrode 150 via a first wiring 152 and a second wiring 154. The RFIC may include a high-power amplifier (“HPA”) and a low-noise amplifier (“LNA”). In such an embodiment, transmitted signals via the HPA may be radiated through the loop antenna electrode 150, and received signals received through the loop antenna electrode 150 may be amplified by the LNA. In an embodiment, the driver may be implemented on an external circuit board electrically connected to the peripheral area PA.

[0058] In such an embodiment, the loop antenna electrode 150 has a C-shape and opposing ends that are respectively connected to the wiring, but the embodiment is not limited thereto. For example, in an alternative embodiment, the loop antenna electrode may have an O-shape and may be connected to a single wiring.

[0059] An optical module (not shown) may be arranged in or overlap with the opening region HA. For example, in one embodiment, the optical module may include a camera module for capturing (or identifying) an image of an object, a face recognition sensor module for detecting a user's face, a pupil recognition sensor module for detecting a user's pupils, an accelerometer module and a geomagnetic sensor module for determining the motion of the display device 10, a proximity sensor module and an infrared sensor module for detecting proximity relative to the front of the display device 10, and an illuminance sensor module for measuring the brightness of external (ambient) light (e.g., when placed in a pocket or bag).

[0060] Figure 3 The diagram shows Figure 2 A cross-sectional view of the display area and the outer perimeter of the opening of the display device.

For example, in one embodiment, the substrate 100 may include at least one selected from quartz substrates, synthetic quartz substrates, calcium fluoride substrates, fluorine-doped quartz substrates (F-doped quartz substrates), soda-lime glass substrates, and non-alkali glass substrates. In an embodiment, the substrate 100 may be configured as a flexible transparent resin substrate. In such embodiments, the transparent resin substrate that can be used as the substrate 100 includes, for example, a polyimide substrate.

[0063] A buffer layer 110 may be disposed above the substrate 100. The buffer layer 110 can prevent metal atoms or impurities from diffusing from the substrate 100 into the active pattern ACT, and can control the heat transfer rate during the crystallization process used to form the active pattern ACT to obtain a substantially uniform active pattern ACT.

[0064] The active pattern ACT of a thin-film transistor (TFT) can be disposed on a buffer layer 110 in the display area DA. In embodiments, the active pattern ACT may comprise amorphous silicon or polycrystalline silicon.

[0070] A source / drain conductive layer may be disposed on the second insulating layer 130. The source / drain conductive layer may include the source electrode SE and drain electrode DE of a thin-film transistor (TFT). The source / drain conductive layer may further include a shielding electrode GND disposed in the opening peripheral region HPA. The source / drain conductive layer may include at least one material selected from metals, alloys, metal nitrides, conductive metal oxides, and transparent conductive materials, or may be formed using at least one material selected from metals, alloys, metal nitrides, conductive metal oxides, and transparent conductive materials.

[0071] Each of the source electrode SE and the drain electrode DE can be electrically connected to the active pattern ACT through a contact hole defined or formed through the second insulating layer 130 and the first insulating layer 120.

[0072] The shielding electrode GND can overlap with the signal line SL in the thickness direction of the substrate 100 in a planar view. A ground voltage or a constant voltage can be applied to the shielding electrode GND. The shielding electrode GND can be arranged between the loop antenna electrode 150 and the signal line SL (which will be described in more detail later) to prevent electrical effects between the loop antenna electrode 150 and the signal line SL, thereby effectively preventing faults caused by electrical effects.

[0073] The via insulating layer VIA can be disposed on a second insulating layer 130 on which an active / drain conductive layer is disposed. The via insulating layer VIA can have a single-layer structure or a multilayer structure comprising at least two insulating layers. In embodiments, the via insulating layer VIA can, for example, comprise organic materials such as photoresists, acrylic resins, polyimide resins, polyamide resins, and siloxane resins, or can be formed using organic materials such as photoresists, acrylic resins, polyimide resins, polyamide resins, and siloxane resins. In alternative embodiments, the via insulating layer VIA can comprise inorganic materials such as silicon compounds, metals, and metal oxides, or can be formed using inorganic materials such as silicon compounds, metals, and metal oxides.

[0074] The light-emitting structure 180 may include a first electrode 181, a light-emitting layer 182, and a second electrode 183.

[0075] The first electrode 181 can be disposed on the through-hole insulating layer VIA.

[0076] A pixel defining layer (PDL) can be disposed on a via insulating layer (VIA) on which the first electrode 181 is disposed. The pixel defining layer (PDL) can include at least one material selected from organic and inorganic materials, or can be formed using at least one material selected from organic and inorganic materials. For example, in one embodiment, the pixel defining layer (PDL) can be formed using at least one material selected from photoresist, polyacrylic resin, polyimide resin, acrylic resin, and silicon compound. In an embodiment, the pixel defining layer (PDL) can be etched to form an opening that partially exposes the first electrode 181. The light-emitting and non-light-emitting areas of the display device 10 can be defined by the opening in the pixel defining layer (PDL). For example, the portion where the opening of the pixel defining layer (PDL) is located can correspond to the light-emitting area, and the portion of the pixel defining layer (PDL) adjacent to the opening can correspond to the non-light-emitting area.

[0077] The light-emitting layer 182 can be disposed on a first electrode 181 exposed through an opening in the pixel-defining layer (PDL).

In an embodiment, the light-emitting layer 182 can have a multilayer structure including an organic light-emitting layer, a hole injection layer, a hole transport layer, an electron transport layer, and an electron injection layer. In an alternative embodiment, the layers of the light-emitting layer 182 other than the organic light-emitting layer (e.g., the hole injection layer, hole transport layer, electron transport layer, and electron injection layer) can be collectively formed to correspond to a plurality of pixels. The organic light-emitting layer of the light-emitting layer 182 can include at least one material selected from light-emitting materials for generating light of different colors, such as red, green, and blue, corresponding to each pixel of the display device 10, or can be formed by using at least one material selected from light-emitting materials for generating light of different colors, such as red, green, and blue, corresponding to each pixel of the display device 10. In one embodiment, the organic light-emitting layer 182 may have a structure in which multiple light-emitting materials for emitting different colors of light, such as red, green, and blue, are stacked to emit white light. In such an embodiment, the light-emitting structures may be collectively configured to correspond to pixels, and pixels may be classified into pixels of different colors based on their corresponding color filter layers.

[0078] The second electrode 183 can be disposed on the pixel defining layer (PDL) and the light-emitting layer 182. In embodiments, depending on the light emission scheme of the display device 10, the second electrode 183 may include a transmissive material or a reflective material. For example, in one embodiment, the second electrode 183 may include at least one material selected from aluminum, aluminum alloys, aluminum nitride, silver, silver alloys, tungsten, tungsten nitride, copper, copper alloys, nickel, chromium, chromium nitride, molybdenum, molybdenum alloys, titanium, titanium nitride, platinum, tantalum, tantalum nitride, neodymium, scandium, strontium ruthenium oxide, zinc oxide, indium tin oxide, tin oxide, indium oxide, gallium oxide, indium zinc oxide, and combinations thereof. In embodiments, the second electrode 183 may have a single-layer structure or a multi-layer structure including a metal film, an alloy film, a metal nitride film, a conductive metal oxide film, and / or a transparent conductive material film.

[0079] A thin-film encapsulation layer (TFE) can be disposed on the second electrode 183. The TFE prevents moisture and oxygen from penetrating through it from the outside. The TFE may include organic and inorganic layers. The organic and inorganic layers may be stacked alternately (or repeatedly). For example, in one embodiment, the TFE may include a first inorganic layer, a second inorganic layer, and an organic layer disposed between the first and second inorganic layers, but the embodiment is not limited thereto. In an alternative embodiment, a sealing substrate may be provided instead of the thin-film encapsulation layer to prevent external air and moisture from penetrating into the display device 10.

[0080] A transparent electrode layer can be disposed on a thin-film encapsulation layer (TFE). The transparent electrode layer may include a touch electrode (TE) disposed in the display area (DA) and a loop antenna electrode (150) disposed in the opening periphery area (HPA). The transparent electrode layer may include a transparent conductive material. For example, in one embodiment, the transparent electrode layer may include materials selected from indium zinc oxide (“IZO”), indium tin zinc oxide (“ITZO”), and zinc oxide (ZnO). x At least one of the following materials: indium tin oxide (“ITO”) and indium tin oxide (“ITO”).

[0081] The transparent electrode layer may further include a first wiring and a second wiring connected to the loop antenna electrode 150 (see...). Figure 2 (152 and 154).

[0082] The optical layer OP can be disposed on a thin-film encapsulation layer TFE on which a transparent electrode layer is disposed. The optical layer OP can be, for example, a polarizer for reducing the reflection of external light. The optical layer OP can be implemented in the form of a film and can be attached using a pressure-sensitive adhesive (“PSA”).

[0083] The cover window (CW) can be disposed on the optical layer (OP). In one embodiment, the cover window CW may include a glass window. In an alternative embodiment, the cover window CW may be a transparent flexible film such as ultrathin glass and transparent polyimide. The cover window CW can be attached to the optical layer (OP) using a PSA or similar method.

[0084] In embodiments, as described above, the signal line SL may be arranged or formed in the gate conductive layer, and the shielding electrode GND may be arranged or formed in the same layer as the source / drain conductive layer; however, embodiments are not limited thereto. For example, in an alternative embodiment, the signal line SL may be arranged or formed in the same layer as the source / drain conductive layer, or may be defined or formed with the source / drain conductive layer by separate or different conductive layers. For example, in an alternative embodiment, the shielding electrode GND may be formed in the same layer as the first electrode 181, or may be defined or formed with the first electrode 181 by separate or different conductive layers. In such embodiments, the loop antenna electrode 150 may be defined or formed by another conductive layer.

[0131] Touchscreen 290 can refer to a display device used to display various applications (e.g., calling, data transmission, broadcasting, and photography) that can be performed by control unit 210 and to provide a user interface suitable for the application. Touchscreen 290 can receive touch gestures (or actions) performed by a user's body (e.g., a finger including the thumb) or a detectable input device (e.g., a stylus). The user interface may include predetermined touch areas, soft keys, and soft menus. Touchscreen 290 can transmit electronic signals corresponding to touch gestures input through the user interface to touchscreen controller 295. In such embodiments, touchscreen 290 can detect continuous touch actions and can transmit electronic signals corresponding to continuous or discontinuous touch actions to touchscreen controller 295.

Utilizing the same methods described above... Figure 8 The same reference numerals are used to label the embodiments of the electronic devices shown.

[0152] In an embodiment, the electronic device may include a display device 10 for displaying images, a front camera module 20, a circuit board 30, a rear camera module 40, a container 50, and a loop antenna 300.

[0155] Figure 13 The figure shows an exploded perspective view of an electronic device according to another alternative embodiment, and Figure 14 It shows Figure 13 Rear view of a portion of the rear camera module of the electronic device.

[0156] Apart from the fact that the loop antenna 300 is adjacent to the rear camera module 40, Figure 13 and Figure 14 The embodiments of the electronic devices shown are similar to Figure 8 The embodiments of the electronic devices are basically the same. Utilizing the same methods described above... Figure 8 The same reference numerals are used to label the embodiments of the electronic devices shown. Figure 13 and Figure 14 The same or similar elements shown herein, and any repeated detailed descriptions thereof will be omitted or simplified below.

[0157] In an embodiment, the electronic device may include a display device 10 for displaying images, a front camera module 20, a circuit board 30, a rear camera module 40, a container 50, and a loop antenna 300.

[0158] The rear camera module 40 can be disposed on the bottom surface of the container 50 (i.e., the rear surface of the electronics). The loop antenna 300 can be disposed within the container 50 and can extend along the surface (e.g., the side surface) of the rear camera module 40. A first wiring 310 and a second wiring 320 can be connected to one end and the opposite end of the loop antenna 300, respectively.

[0159] In embodiments of the present invention, the loop antenna of the electronic device or the loop antenna electrode embedded in the display device can be implemented as an antenna for fourth-generation (4G) communication services, and can also be implemented as an antenna for fifth-generation (5G) communication services.

[0160] In such embodiments, frequencies of 2 GHz or lower are primarily used for 4G mobile communications, while, unlike 4G Long Term Evolution (“LTE”), approximately 28 GHz or 39 GHz (ultra) high-frequency bands are used for 5G mobile communications. Low-frequency bands have long wavelengths and therefore wide coverage, but communications using low-frequency bands have relatively narrow bandwidths and therefore low transmission rates. In this context, high-frequency bands have short wavelengths and therefore narrow coverage, but communications using high-frequency bands have relatively wide bandwidths and therefore high transmission rates. Furthermore, the coverage limitations of communications using high-frequency bands can be mitigated to some extent by utilizing the high linear propagation characteristics of (ultra) high-frequency bands and array antennas, etc. Therefore, 5G mobile communications can address capacity shortages by increasing capacity, providing users with a variety of communication services, and offering mobile internet technology and machine-to-machine (“M2M”) technology.

[0161] If conventional printed antennas implemented on a circuit board or conventional chip antennas arranged on a circuit board are used as antennas for 5G mobile communications, the performance of the 5G mobile communication antenna may be degraded. In particular, printed antennas or chip antennas have considerable losses in 5G frequency bands (e.g., 28GHz or 39GHz bands).

[0162] In embodiments of the invention, the display device or electronic device includes a loop antenna or loop antenna electrodes arranged in a space-saving manner. Therefore, in such embodiments, antenna elements can be arranged on the front, side, and / or rear surfaces of the electronic device to be oriented in various directions, and thus the performance of the antenna elements can be improved.

[0163] Embodiments of the present invention can be applied to display devices and electronic devices including such display devices, such as smartphones, cellular phones, video phones, smart panels, smartwatches, tablet computers, car navigation systems, televisions, computer monitors, laptop computers, head-mounted display (HMD) devices, etc.

[0164] This invention should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the invention to those skilled in the art.

[0165] Although the invention has been specifically shown and described with reference to embodiments thereof, those skilled in the art will understand that various changes in form and detail may be made therein without departing from the spirit and scope of the disclosure as defined by the appended claims.
