DETAILED DESCRIPTION

(17) The present disclosure relates generally to a display device. More particularly, to a display device with increased antenna efficiency. Specifically, embodiments of the present disclosure provide shielding around antenna components to direct the energy transmitted to/from the antenna and to protect the antenna from interference.

(18) With mobile devices becoming smaller, the space used for electronic modules is becoming smaller as well. Additionally, as these devices provide more complex and powerful features, the quantity of electronic modules used in the devices increases to maintain an acceptable performance level. As the electronic modules become more compressed within a device, noise from some components can interfere with the operation of radio antennas.

(19) Accordingly, embodiments of the present disclosure include a display panel, an active area, a peripheral area, an input sensor, and a pattern layer. The active area and the peripheral area are adjacent to the active area. The input sensor is disposed on the display panel and includes a plurality of detection electrodes and a first pattern. The pattern layer is disposed on the input sensor and includes a second pattern overlapping the first pattern when viewed on a plane. Any one of the first and second patterns transmits and receives a signal. The other pattern of the first and second patterns includes a shielding component that shields or reflects a signal provided from one pattern. A transmission component transmits the signal.

(20) Additional embodiments of the present disclosure use the shielding component to shield or reflect a signal from an antenna pattern. The transmission component may transmit a signal provided by the antenna pattern. An additional pattern may shield or reflect a portion of the signal and transmit another portion of the signal. The additional pattern may modify the signal provided from the antenna pattern. The modified signal may improve antenna gain and directivity of the antenna signal of the display device. As a result, the present disclosure provides the display device with improved antenna efficiency.

(21) In this specification, when the present disclosure mentions that a component (or, an area, a layer, a component, etc.) is referred to as being “on”, “connected to” or “combined to” another component, this means that the component may be directly on, connected to, or combined to the other component or a third component therebetween may be present.

(22) Like reference numerals refer to like elements. Additionally, in the drawings, the thicknesses, proportions, and dimensions of components are exaggerated for effective description. “And/or” includes all of one or more combinations defined by related components.

(23) It will be understood that the terms “first” and “second” are used herein to describe various components but these components should not be limited by these terms. The above terms are used to distinguish one component from another. For example, a first component may be referred to as a second component and vice versa without departing from the scope of the inventive concept. The terms of a singular form may include plural forms unless otherwise specified.

(24) Additionally or alternatively, terms such as “below”, “the lower side”, “on”, and “the upper side” are used to describe a relationship of configurations shown in the drawing. The terms are described as a relative concept based on a direction shown in the drawing.

(25) Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as terms commonly understood by those skilled in the art to which this invention belongs. In general, the terms defined in the dictionary should be considered to have the same meaning as the contextual meaning of the related art, and, unless clearly defined herein, should not be understood abnormally or with an excessively formal meaning.

(26) In various embodiments of the inventive concept, the term “include,” “comprise,” “including,” or “comprising,” specifies a property, a region, a fixed number, a step, a process, an element and/or a component but does not exclude other properties, regions, fixed numbers, steps, processes, elements and/or components.

(62) The input detection unit ISL may obtain information on an external input from a change in capacitance between the plurality of first detection electrodes TE1 and the plurality of second detection electrodes TE2.

(63) The plurality of first detection electrodes TE1 may be disposed on the base insulating layer BS2. Each of the plurality of first detection electrodes TE1 may extend along the first direction DR1 and may be arranged along the second direction DR2. Each of the plurality of first detection electrodes TE1 may include a plurality of first detection patterns SP1 and a plurality of first connection patterns BP1.

(67) The plurality of antenna patterns ANT may be disposed in the second active area IS-AA2, and the plurality of antenna pads ANP may be disposed in the peripheral area IS-NAA. The plurality of antenna lines ANL may electrically connect the plurality of antenna patterns ANT and the plurality of antenna pads ANP. The first pattern PT1 (see FIG. 2) may be a plurality of antenna patterns ANT.

(68) The plurality of antenna patterns ANT may be disposed on the same layer as the plurality of detection electrodes TE1 and TE2. For example, the plurality of antenna patterns ANT may be disposed on the base insulating layer BS2.

(69) The plurality of antenna patterns ANT may include the same material as the plurality of detection electrodes TE1 and TE2. The plurality of antenna patterns ANT may be formed through the same process as the plurality of detection electrodes TE1 and TE2. For example, the plurality of detection electrodes TE1 and TE2 and the plurality of antenna patterns ANT may include a carbon nanotube, a metal and/or metal alloy, or a composite material thereof, and may have a single-layer or multi-layer structure. However, this is an example.

(70) Therefore, the plurality of antenna patterns ANT, according to an embodiment of the inventive concept, may include a different material than the plurality of detection electrodes TE1 and TE2 and may be formed through a separate process. For example, the plurality of detection electrodes TE1 and TE2 may have a multi-layer structure where titanium (Ti), aluminum (Al), and titanium (Ti) are sequentially stacked, and the plurality of antenna patterns ANT may include carbon nanotubes, metal and/or metal alloys, or composite materials thereof, and may have a single layer or multi-layer structure. For example, the metal material may be silver (Ag), copper (Cu), aluminum (Al), gold (Au), or platinum (Pt), but is not limited thereto.

(71) When viewed on a plane, the plurality of antenna patterns ANT may overlap the active area DP-AA (see FIG. 3) of the display panel DP (see FIG. 3). The plurality of antenna patterns ANT may have a mesh structure so that the image IM (see FIG. 1) provided in the active area DP-AA (see FIG. 3) can be transmitted. The mesh structure may mean a structure where a plurality of openings are defined in a given layer.

(74) The input sensor IS may further include at least one ground electrode disposed under the base insulating layer BS2. However, this is exemplary and the ground electrode, according to an embodiment of the inventive concept, is not limited thereto. For example, the ground electrode according to an embodiment of the inventive concept may be a component of the configuration of the display panel DP (see FIG. 3).

(75) FIG. 5 is an enlarged plan view of area AA′ of FIG. 4 according to an embodiment of the inventive concept.

(78) The dummy pattern DMP may be disposed in the dummy area DMA between the first active area IS-AA1 and the antenna area ANA. As the dummy pattern DMP is disposed, a difference in reflectance between a portion where the antenna pattern ANT is disposed and a portion where the antenna pattern ANT is not disposed may be decreased. Therefore, the antenna pattern ANT may be prevented from being viewed from the outside. Additionally or alternatively, each of the reflectance and transmittance of the dummy area DMA may be different from each of the reflectance and transmittance of the first active area IS-AA1 and the antenna area ANA when the dummy pattern DMP is not disposed. However, as the dummy pattern DMP is disposed, a difference between the reflectance and a difference between the transmittance may be decreased. As a result, a phenomenon where a specific boundary such as a boundary between the antenna pattern ANT and the second detection pattern SP2, or a boundary between the antenna pattern ANT and the second connection pattern BP2 is viewed, may be prevented.

(79) The antenna pattern ANT may have a first width ANT-L in the first direction DR1. The first width ANT-L of the antenna pattern ANT may have a value of ½ of the wavelength of the frequency of the signal transmitted and received by the antenna pattern ANT. However, this is exemplary and the first width ANT-L of the antenna pattern ANT, according to an embodiment of the inventive concept, is not limited thereto. For example, the first width ANT-L of the antenna pattern ANT may have a value of ¼ of the wavelength of the frequency of the signal transmitted and received by the antenna pattern ANT.

(80) The antenna pattern ANT may have a second width ANT-W in the second direction DR2. The second width ANT-W of the antenna pattern ANT may be the same as the first width ANT-L of the antenna pattern ANT. However, this is exemplary and the first width ANT-L of the antenna pattern ANT and the second width ANT-W of the antenna pattern ANT according to an embodiment of the inventive concept are not limited thereto.
