Technical Field

[0002] Traditional cathode ray tube (CRT) televisions have been widely used in display devices due to their performance and price.

[0044] In the following sections, embodiments of the inventive concept will be explained in detail with reference to the accompanying drawings.
[0045] Figure 1 This is a plan view illustrating a display device according to an embodiment of the concept of the present invention.
[0046] refer to Figure 1 The display device may include a display area DA and a peripheral area PA that is a non-display area and adjacent to the display area DA.
[0047] The display area DA is an area configured to display an image and can be set on a plane provided by a first direction D1 and a second direction D2 that is substantially perpendicular to the first direction D1.
[0048] A display device may include a plurality of pixels for displaying an image in a display area DA. For example, a display device may include n*m pixels (where n and m are integers greater than 1) located at the intersection of a scan line extending in a first direction D1 and a data line extending in a second direction D2. Various known structures can be applied to the structure of the pixels.
[0049] The display area DA may include a touch area TA and a non-touch area AA surrounding the touch area TA. (Touch electrodes - see below) Figure 5 The TE (touch electrode) can be set in the touch area TA so that the user's touch input can be detected. The touch electrode may not be formed in the non-touch area AA.
[0050] The peripheral region PA may at least partially surround the display region DA and may not display an image. In this case, the circuitry and wiring for driving the pixels of the display region DA can be located in the peripheral region PA.
[0051] Figure 2 It is a diagram. Figure 1 An enlarged view of part A in the display device. Figure 3 It is a diagram. Figure 2 An enlarged view of the antenna electrodes in the display device, and Figure 4 It is a diagram. Figure 2 The diagram shows the shapes of the lattice patterns in the touch area, the third area, the second area, and the first area of the display device.
[0052] refer to Figures 1 to 4 The display device may include a touch area TA, a non-touch area AA, and a peripheral area PA.
[0053] The non-touch area AA may include a first area AA1, a second area AA2, and a third area AA3. The first area AA1, the second area AA2, and the third area AA3 may be sequentially set from the peripheral area PA to the touch area TA. In other words, the first area AA1 may be set between the peripheral area PA and the second area AA2, the second area AA2 may be set between the first area AA1 and the third area AA3, and the third area AA3 may be set between the second area AA2 and the touch area TA.
[0054] Antenna electrode ATE and first dummy pattern DM1 can be disposed in first region AA1. Antenna electrode ATE can be used for communication functions and can be connected to feed line ATL disposed in peripheral region PA. Feed line ATL can be connected to an external antenna driving unit via external connection electrode disposed in peripheral region PA, or electrically connected to the antenna driving unit disposed in peripheral region PA.
[0055] The antenna electrode ATE may include a lattice pattern. For example, the lattice pattern may include a quadrilateral shape with four sides of substantially the same length. For example, the lattice pattern may have multiple rhomboid shapes arranged along a first direction D1 and a second direction D2 substantially perpendicular to the first direction D1. For example, the lattice pattern may have long rhomboid shapes in the second direction (i.e., the longitudinal direction) D2. For example, the rhomboid shapes of the lattice pattern may have lengths different from their widths.
[0056] The rhombus shape may have a first height H1 and a first width W1, and may have a first linewidth d1. For example, the first width W1 may be approximately 130 μm (micrometers), the first height H1 may be approximately 260 μm, and the first linewidth d1 may be from approximately 1 μm to approximately 2.5 μm.
[0057] The quadrilateral shape of the lattice pattern of the antenna electrode ATE can form a vertex angle a1 of less than 90 degrees. For example, the vertex angle a1 can be approximately 53 degrees. The quadrilateral shape can also have another vertex angle b1, which can be approximately 127 degrees.
[0058] Multiple antenna electrodes (ATEs) can be spaced apart from each other. In this case, beamforming can be achieved by changing the phase of the signal applied to each antenna electrode.
[0059] The feed line ATL can be electrically connected to the antenna electrode ATE. The feed line ATL can also be electrically connected to the antenna drive unit.
[0060] The antenna driving unit can perform transmission and reception communication functions by transmitting electrical signals to or receiving electrical signals from the antenna electrode ATE.
[0061] For example, the antenna driving unit may include a radio frequency integrated circuit (RFIC) configured to feed power to the antenna electrode ATE. The RFIC may include a high-power amplifier (HPA) and a low-noise amplifier (LNA). The transmitted signal can be transmitted through the high-power amplifier (HPA) and transmitted to the antenna electrode ATE. The transmitted signal can be radiated via the antenna electrode ATE, and the received signal received via the antenna electrode can be amplified by the low-noise amplifier (LNA).
[0062] Since the first dummy pattern DM1 is disposed adjacent to the antenna electrode ATE, the first dummy pattern DM1 can have the same lattice pattern shape as the antenna electrode ATE. For example, the lattice pattern of the antenna electrode ATE can be smaller than the lattice pattern of the first dummy pattern DM1 or the same as the lattice pattern of the first dummy pattern DM1.
[0063] The first dummy pattern DM1 can be spaced apart from the antenna electrode ATE. For example, the lattice pattern can be continuous in the first region AA1 and can have a shape cut at the edge of the antenna electrode ATE (see [reference]). Figure 3 (CUT in the diagram). In addition, multiple cutouts can be formed inside the first dummy pattern DM1.
[0064] The first quadrilateral shape of the lattice pattern of the first dummy pattern DM1 can have a vertex angle of less than 90 degrees. For example, the first quadrilateral shape can be formed with a first vertex angle a1 greater than or equal to the vertex angle ATE of the antenna electrode. The first quadrilateral shape can have another vertex angle.
[0065] The first dummy pattern DM1 may have a first linewidth. The first linewidth d1 of the lattice pattern of the antenna electrode ATE may be less than or equal to the first linewidth of the first dummy pattern DM1.
[0066] Even within the first region AA1, the first dummy pattern DM1 can vary in size and shape. For example, as the first dummy pattern DM1 moves closer to the second region AA2, the size of the lattice pattern can increase, the first vertices can increase, and the first linewidth can gradually increase. For example, the portion of the first dummy pattern DM1 closest to the second region AA2 can have a larger size, a larger first vertices, and a larger first linewidth than the portion of the first dummy pattern DM1 furthest from the second region AA2. For example, the openings in the lattice pattern of the first dummy pattern DM1 can become larger.
[0067] The second dummy pattern DM2 can be set in the second area AA2.
[0068] The second dummy pattern DM2 may include a lattice pattern having a size or shape different from that of the first dummy pattern DM1. For example, the lattice pattern may include a quadrilateral shape with four sides having substantially the same length. In other words, the lattice pattern may have multiple rhomboid shapes arranged along a first direction D1 and a second direction D2. For example, the lattice pattern may have a long rhomboid shape in the longitudinal direction D2. The rhomboid shape may have a second height H2 greater than the first height of the first quadrilateral shape of the first dummy pattern DM1 and a second width W2 greater than the first width of the first quadrilateral shape of the first dummy pattern DM1.
[0069] The second quadrilateral shape of the lattice pattern of the second dummy pattern DM2 may include a vertex angle less than 90 degrees. For example, the second quadrilateral shape may be formed with a second vertex angle a2 that is greater than the first vertex angle of the first dummy pattern DM1. The second dummy pattern DM2 may have a second linewidth d2 that is greater than the first linewidth of the first dummy pattern DM1. The second quadrilateral shape may have another vertex angle b2.
[0070] Even within the second region AA2, the second dummy pattern DM2 can vary in size and shape. For example, as the second dummy pattern DM2 moves closer to the third region AA3, the size of the lattice pattern can increase, the second vertex angle a2 can increase, and the second linewidth d2 can gradually increase.
[0071] The third dummy pattern DM3 can be set in the third area AA3.
[0072] The third dummy pattern DM3 may include a lattice pattern having a size or shape different from that of the second dummy pattern DM2. For example, the lattice pattern may include a quadrilateral shape with four sides having substantially the same length. For example, the lattice pattern may have multiple rhomboid shapes arranged along a first direction D1 and a second direction D2. For example, the lattice pattern may have long rhomboid shapes in the longitudinal direction D2. The rhomboid shapes may have a third height H3 greater than the second height H2 of the second dummy pattern DM2 and a third width W3 greater than the second width W2 of the second dummy pattern DM2.
[0073] The third quadrilateral shape of the lattice pattern of the third dummy pattern DM3 may include a vertex angle less than 90 degrees. For example, the third quadrilateral shape may be formed with a third vertex angle a3 that is greater than the second vertex angle a2 of the second dummy pattern DM2. The third dummy pattern DM3 may have a third linewidth d3 that is greater than the second linewidth d2 of the second dummy pattern DM2. The third quadrilateral shape may have another vertex angle b3.
[0074] Even within the third region AA3, the third dummy pattern DM3 can vary in size and shape. For example, as the third dummy pattern DM3 moves closer to the touch region TA, the size of the lattice pattern can increase, the third vertex a3 can increase, and the third linewidth d3 can gradually increase.
[0075] A touch electrode TE can be disposed in the touch area TA. The touch electrode TE may include a lattice pattern having a size or shape different from the lattice pattern of the third dummy pattern DM3. For example, the lattice pattern may be formed of a quadrilateral shape. For example, the quadrilateral is arranged in a rhombus shape and may have a size of approximately 3.9 mm in the diagonal direction. The rhombus shape may have a height HT greater than the third height H3 of the third dummy pattern DM3 and a width WT greater than the third width W3 of the third dummy pattern DM3.
[0076] For example, the lattice pattern of the touch electrode TE can be greater than or equal to the lattice pattern of the third dummy pattern DM3. The linewidth dT of the lattice pattern of the touch electrode TE can be greater than or equal to the third linewidth d3 of the third dummy pattern DM3. The quadrilateral shape of the lattice pattern of the touch electrode TE can include vertices with angles less than 90 degrees. For example, the quadrilateral shape can be formed with a vertices aT greater than the third vertices a3 of the third dummy pattern DM3. The quadrilateral shape can have another vertices bT.
[0077] In other words, the size of the lattice pattern can increase from the first region AA1 to the third region AA3, and a dummy pattern DM containing a lattice pattern with gradually changing sizes can be positioned between the antenna electrode ATE and the touch region TA, where the lattice pattern has a very small size compared to the lattice pattern of the touch electrode TE. Furthermore, in embodiments of the present invention, the density of the dummy pattern DM can gradually increase in the direction from the touch region TA to the antenna electrode ATE. Additionally, the dummy pattern DM can be configured to have a shape that gradually increases in size in the direction from the antenna electrode ATE to the touch region TA. Accordingly, the problem of visually perceptible blemishes by the user due to the size difference between the lattice patterns of the touch electrode TE and the antenna electrode ATE can be solved (or, for example, mitigated).
[0078] In addition, from the first region AA1 to the third region AA3, only the size and shape of the lattice pattern can be changed and the linewidth can be the same, or only the size can be changed and the shape and linewidth can be the same.
[0079] Figure 5 It is a diagram. Figure 2 Cross-sectional views of the touch area, the third area, and the first area in a display device.

[0081] The substrate 100 may comprise transparent or opaque materials. For example, the substrate 100 may be a flexible substrate. For example, the substrate 100 may comprise a quartz substrate, a synthetic quartz substrate, a calcium fluoride substrate, a fluorine-doped (F-doped) quartz substrate, a soda-lime glass substrate, an alkali-free glass substrate, etc. Alternatively, the substrate 100 may be formed of a transparent resin substrate. For example, a transparent resin substrate that can be used for the substrate 100 may include a polyimide substrate as an example. In this case, the polyimide substrate may include a first polyimide layer, a barrier film layer, a second polyimide layer, etc.
[0082] A buffer layer 110 may be disposed on the substrate 100. The buffer layer 110 can prevent metal atoms or impurities from diffusing from the substrate 100 to the thin-film transistors TFTs, TFT1, and TFT3, and can control the rate of heat transfer, so that the active pattern ACT is acquired substantially uniformly during the crystallization process for forming the active pattern ACT of the thin-film transistors. Additionally, when the surface of the substrate 100 is non-uniform or uneven, the buffer layer 110 can improve the flatness of the surface of the substrate 100. Depending on the type of substrate 100, at least two buffer layers may be provided on the substrate 100, or the buffer layer 110 may not be disposed on the substrate 100. For example, the buffer layer 110 may comprise organic and / or inorganic materials.
[0083] The active pattern ACT of the thin-film transistor (TFT) can be disposed on the buffer layer 110. For example, the active pattern ACT can include metal-oxide-semiconductor, inorganic semiconductor (such as amorphous silicon), polycrystalline silicon, organic semiconductor, etc. The active pattern ACT can have a source region, a drain region, and a channel region between the source and drain regions.

For example, the insulating layers may have different thicknesses or comprise different materials. However, the inventive concept is not limited thereto, and for example, the first insulating layer 120 may be a single-layer structure.
[0085] The gate pattern, including the gate electrode GE, can be disposed on the first insulating layer 120. The gate pattern can be configured to overlap with the channel region of the active pattern ACT. The gate electrode GE can include, for example, a metal, an alloy, a metal nitride, a conductive metal oxide, a transparent conductive material, etc.
[0086] The second insulating layer 130 may be disposed on the gate pattern. The second insulating layer 130 may include, for example, silicon compounds, metal oxides, etc. Alternatively, the second insulating layer 130 may have a multilayer structure comprising multiple insulating layers. For example, the insulating layers may have different thicknesses or comprise different materials. However, the inventive concept is not limited thereto, and for example, the second insulating layer 130 may be a single-layer structure.
[0087] Data patterns, including the source electrode SE and drain electrode DE of a thin-film transistor (TFT), can be disposed on a second insulating layer 130. The source electrode SE can be connected to the source region of the active pattern ACT via contact holes formed in the first insulating layer 120 and the second insulating layer 130 by removing a first portion of the first insulating layer 120 and the second insulating layer 130, and the drain electrode DE can be connected to the drain region of the active pattern ACT via contact holes formed in the first insulating layer 120 and the second insulating layer 130 by removing a second portion of the first insulating layer 120 and the second insulating layer 130. The data pattern can include, for example, metals, alloys, metal nitrides, conductive metal oxides, transparent conductive materials, etc. The above materials can be used alone or in combination. In embodiments of the inventive concept, the data pattern can have a multilayer structure comprising multiple metal layers. For example, the metal layers can have different thicknesses and / or comprise different materials.
[0088] A thin-film transistor (TFT) can be disposed in the touch area TA, a first TFT1 can be disposed in the first area AA1, and a third TFT3 can be disposed in the third area AA3. Although the TFT has been described as having a top-gate structure, the configuration of the present invention is not limited thereto. For example, the TFT can have a bottom-gate structure, a dual-gate structure, etc.
[0089] A via insulating layer VIA can be disposed on the second insulating layer 130 and the data pattern. For example, the via insulating layer VIA can be configured to have a relatively thick thickness. In this case, the via insulating layer VIA can have a substantially flat upper surface. To achieve the flat upper surface of the via insulating layer VIA as described above, a planarization process can be added to the via insulating layer VIA. Alternatively, the via insulating layer VIA can be configured to have a substantially uniform thickness along the contour of the data pattern on the second insulating layer 130. The via insulating layer VIA can be formed from, for example, organic or inorganic materials. In embodiments of the inventive concept, the via insulating layer VIA may include organic materials. For example, the via insulating layer VIA may include photoresist, polyacrylate resin, polyimide resin, polyamide resin, siloxane resin, acrylic resin, epoxy resin, etc.
[0090] The first electrode 181 can be disposed on the via insulating layer VIA. The first electrode 181 can be electrically connected to the thin-film transistor (TFT) via a contact hole in the via insulating layer VIA formed by removing a portion of the via insulating layer VIA. The first electrode 181 can include, for example, a metal, an alloy, a metal nitride, a conductive metal oxide, a transparent conductive material, etc. The above materials can be used alone or in combination. In embodiments of the inventive concept, the first electrode 181 can have a multilayer structure comprising multiple metal layers. For example, the metal layers can have different thicknesses or comprise different materials. However, the inventive concept is not limited thereto. For example, the first electrode 181 can be a single-layer structure.
[0091] A pixel defining layer (PDL) can be disposed on the via insulating layer (VIA). For example, the pixel defining layer (PDL) may include an opening that can expose a portion of the upper surface of the first electrode 181 while covering both sides of the first electrode 181. The pixel defining layer (PDL) may be formed of an organic or inorganic material. In embodiments of the present invention, the pixel defining layer (PDL) may include an organic material.
[0092] A light-emitting layer 182 can be disposed on the pixel-defining layer PDL and the first electrode 181. The light-emitting layer 182 can be formed using a light-emitting material capable of emitting colored light (such as red, green, and blue light), and each sub-pixel including the light-emitting material can emit red, green, or blue light. Alternatively, the light-emitting layer 182 can be formed by laminating multiple light-emitting materials capable of generating different colors of light, such as red, green, and blue light, so that white light can be emitted. In this case, a color filter can be disposed on the light-emitting layer 182 disposed on the first electrode 181. The color filter can include at least one of a red color filter, a green color filter, and a blue color filter. Alternatively, the color filter can also include a yellow color filter, a cyan color filter, and a magenta color filter. The color filter can include a photosensitive resin or a colored photoresist.

In embodiments of the inventive concept, the second electrode 183 may have a multilayer structure comprising multiple layers. For example, the metal layers may have different thicknesses and / or comprise different materials. However, the inventive concept is not limited thereto, and for example, the second electrode 182 may be a single-layer structure.
[0094] The light-emitting structure 180 can be disposed in the touch area TA, the first light-emitting structure 180a can be disposed in the first area AA1, and the third light-emitting structure 180c can be disposed in the third area AA3.
[0095] The thin-film encapsulation layer TFE can be configured to cover the light-emitting structure 180, the first light-emitting structure 180a, and the third light-emitting structure 180c. The thin-film encapsulation layer TFE may include at least one alternately laminated inorganic and organic layers. For example, the thin-film encapsulation layer TFE may include a first inorganic layer, an organic layer on the first inorganic layer, and a second inorganic layer on the organic layer. The thin-film encapsulation layer TFE can prevent the light-emitting layer 182 from deteriorating due to the penetration of moisture, oxygen, etc. In addition, the thin-film encapsulation layer TFE can also protect the internal structure from external impacts. Furthermore, the thin-film encapsulation layer TFE can increase flatness.
[0096] The touch electrode TE, the third dummy pattern DM3, and the antenna electrode ATE can be disposed on the thin-film encapsulation layer TFE.
[0097] The antenna electrode ATE, the third dummy pattern DM3, and the touch electrode TE can each be formed of, for example, silver (Ag), aluminum, copper, or an alloy. In embodiments of the present invention, the antenna electrode ATE, the third dummy pattern DM3, and the touch electrode TE can be formed as a transparent conductive layer.
[0098] The optical layer OP can be disposed on a thin-film encapsulation layer TFE on which antenna electrodes ATE, a third dummy pattern DM3, and touch electrodes TE are disposed. For example, the optical layer OP can be a polarizer configured to reduce external light reflection. The optical layer OP can be implemented in the form of a film and can be bonded to the antenna layer using a pressure-sensitive adhesive (PSA).
[0099] The cover window (CW) can be mounted on the optical layer (OP). The cover window (CW) can be bonded to the optical layer (OP) using an adhesive film. The cover window (CW) can form part of the outer surface of an electronic device, including a display device (such as a smartphone).
[0100] Despite Figure 5 The second dummy pattern set in the second region and the first dummy pattern set in the first region are not illustrated, but the first dummy pattern and the second dummy pattern can be configured to have a cross-sectional shape similar to the third dummy pattern DM3 set in the third region AA3, so their detailed description can be omitted.
[0101] Figure 6 This is an enlarged view illustrating the antenna electrodes in a display device according to an embodiment of the present invention, and Figures 7A to 7H This is a diagram illustrating examples of internal dummy patterns formed on antenna electrodes and dummy patterns in display devices according to embodiments of the present invention.
[0102] refer to Figure 6 Display devices and Figures 1 to 5 The display devices are essentially the same, except that the internal dummy pattern (IDM) is set in a lattice pattern. For example, the internal dummy pattern (IDM) can be located in a predetermined position within the lattice pattern. Therefore, repeated descriptions can be omitted.
[0103] The display device may include antenna electrodes ATE and dummy pattern DM1.
[0104] Antenna electrodes (ATE) can be directly formed on the thin-film encapsulation layer of the display device (see [reference]). Figure 5 The TFE (transfer element) can be attached, or it can be attached in the form of a film. In this case, the interference pattern visible to the user can be formed by the repetition period of the pixel structure constituting the pixel and the period of the lattice pattern of the antenna electrode ATE and the dummy pattern DM.
[0105] When pixel structures and lattice patterns overlap, high-frequency components that are invisible in each pattern of pixel structures and lattice patterns can generate patterns of low-frequency components that are noticeable to the user, thus forming a moiré pattern.
[0106] According to this embodiment, as shown in the figure, the internal dummy pattern IDM can be set in the lattice pattern, thereby affecting the high-frequency components and reducing the recognition of the moiré pattern.
[0107] Therefore, according to this embodiment, although the antenna electrode ATE and the like are formed using a metal mesh with high reflectivity, such as silver, the user's ability to identify blemishes can be reduced due to the gradual size variation of the dummy pattern DM and the setting of the internal dummy pattern IDM. For example, the internal dummy patterns IDM can be spaced apart from each other.
[0108] Figures 7A to 7H Examples of various shapes and arrangements of internal dummy patterns (IDMs) set in the lattice pattern or dummy pattern DM of the antenna electrode ATE are shown. For example, the internal dummy patterns (IDMs) can have different shapes from each other (see [reference]). Figure 7B or Figure 7F IDMa and IDMb in (the context of IDMa and IDMb).
[0109] refer to Figure 7A The internal dummy pattern IDM can extend in the first direction D1 and can be set in the lattice pattern of the dummy pattern DM and / or the antenna electrode ATE.

For example, the first internal dummy pattern IDMa can have two adjacent patterns extending in the first direction D1, and the second internal dummy pattern IDMb can be a single pattern extending in the first direction D1.
[0111] refer to Figure 7C and Figure 7D The internal dummy pattern IDM can be disposed in the lattice pattern of the dummy pattern DM and / or the antenna electrode ATE, and can extend in a direction intersecting the first direction D1 and the second direction D2 (e.g., a diagonal direction). For example, the internal dummy pattern IDM can be disposed in each opening of the lattice pattern of the dummy pattern DM and / or the antenna electrode ATE.
[0112] refer to Figures 7E to 7HInternal dummy pattern (IDM) can extend in various directions and have various shapes and configurations. For example, an internal dummy pattern (IDM) can extend in multiple directions and can include gaps or openings.

[0115] The display area DA may include a main display area MDA and a first edge display area EA1 and a second edge display area EA2 adjacent to the main display area MDA. For example, the main display area MDA may have a quadrilateral shape extending along a first direction D1 and a second direction D2 substantially perpendicular to the first direction D1. The first edge display area EA1 and the second edge display area EA2 may extend along the second direction D2 and may be respectively connected to the right and left sides of the main display area MDA in the first direction D1.

[0116] Antenna electrode ATE can be set in the first region AA1. Dummy pattern DM can be set in the first region AA1 to the third region AA3. Touch electrode TE can be set in the touch region TA.
[0117] like Figure 9 As shown, the peripheral region PA can be bent to lie on the rear surface of the first edge display region EA1, and a drive unit 20 configured to drive the display device can be connected to the peripheral region PA. The drive unit 20 may include an RFIC configured to feed power to the antenna electrode ATE.
[0118] Figure 10 This is a cross-sectional view illustrating an embodiment of a display device according to the present invention.
[0119] refer to Figure 10 Display devices and Figure 8 and Figure 9The display devices are essentially the same, except that the touch area TA extends into a portion of the curved part of the display device. Therefore, repeated descriptions can be omitted.
