[0058] In the following description, exemplary embodiments will be illustrated in more detail with reference to the accompanying drawings, in which the same reference numerals consistently denote the same elements. However, this disclosure may be implemented in a variety of different forms and should not be construed as being limited to the embodiments shown herein. Rather, these embodiments are provided as examples so that this disclosure will be thorough and complete, and will fully convey to those skilled in the art the aspects and features of this disclosure. Therefore, processes (handlings or procedures), elements (factors), and techniques unnecessary for those skilled in the art to fully understand the aspects and features of this disclosure may not be described. Unless otherwise indicated, the same reference numerals denote the same elements throughout the drawings and textual description, and therefore their description need not be repeated.

[0059] In the accompanying drawings, for clarity, the relative dimensions of elements, layers, and regions may be exaggerated and / or simplified. For ease of interpretation, spatial relative terms such as “below,” “under,” “below,” “below,” “above,” “above,” etc., are used herein to describe the relationship between one element or feature shown in the figures and another (other) element or feature. It will be understood that spatial relative terms are intended to encompass different orientations of the device in use or operation other than those described in the figures. For example, if the device in the figures is flipped, an element described as “below” or “below” or “below” other elements or features would then be positioned “above” said other elements or features. Thus, the example terms “below” and “below” can encompass both above and below orientations. The device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), and the spatial relative descriptive terms used herein should be interpreted accordingly.

[0060] It will be understood that although the terms “first,” “second,” “third,” etc., may be used herein to describe various elements, components, regions, layers, and / or portions, these elements, components, regions, layers, and / or portions should not be limited by these terms. These terms are used to distinguish one element, component, region, layer, or portion from another element, component, region, layer, or portion. Therefore, without departing from the spirit and scope of this disclosure, the first element, component, region, layer, or portion described below may be referred to as a second element, component, region, layer, or portion.

[0061] It will be understood that when an element or layer is referred to as being "on," "connected to," or "bonded to" another element or layer, the element or layer may be directly on, directly connected to, or directly bonded to the other element or layer, or there may be one or more intermediate elements or intermediate layers. Furthermore, it will be understood that when an element or layer is referred to as being "between" two elements or layers, the element or layer may be the only element or only layer between the two elements or layers, or there may be one or more intermediate elements or intermediate layers.

[0062] The terminology used herein is for the purpose of describing particular embodiments and is not intended to be limiting of this disclosure. As used herein, unless the context clearly indicates otherwise, the singular forms “a” and “an” are also intended to include the plural forms. It will also be understood that when the terms “comprising,” “including,” and “having,” and variations thereof are used in this specification, they indicate the presence of the stated features, integrals, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or groups thereof. As used herein, the term “and / or” includes any and all combinations of one or more of the associated listed items. When a statement such as “at least one of…” follows a list of elements, it modifies the entire list of elements without modifying any individual elements within that list.

[0063] As used herein, the terms “basically,” “approximately,” and similar terms are used as approximate terms rather than as terms of degree, and are intended to account for inherent deviations in measurements or calculations that will be recognized by those skilled in the art. Furthermore, when describing embodiments of this disclosure, the use of “may” indicates “one or more embodiments of this disclosure.” As used herein, the term “use” and variations thereof may be considered synonymous with the term “utilize” and variations thereof, respectively. Additionally, the term “exemplary” is intended to indicate an example or illustration.

[0064] Unless otherwise defined, 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 also be understood that terms (such as those defined in a general dictionary) shall be interpreted as having the same meaning as they have in the relevant field and / or the context of this specification, and shall not be interpreted in an idealized or overly formal sense, unless expressly defined herein.

[0066] As used herein, a display (e.g., display 1) is a device for displaying moving images or still images and can be used as a display screen for various products, such as for various portable electronic devices and / or for various display devices. Examples of such portable electronic devices may include mobile phones, smartphones, tablet PCs, smartwatches, watch phones, mobile communication terminals, e-notebooks, e-book readers, portable multimedia players (PMPs), navigation systems, and / or ultra-mobile PCs, etc. Examples of such display devices may include televisions, laptop PCs, monitors, advertising panels, and / or Internet of Things (IoT) devices, etc. In an exemplary embodiment, display 1 may be a display for a vehicle (e.g., an automotive display), but this disclosure is not limited thereto.

[0067] Reference Figures 1 to 7 Display 1 may have a rectangular shape in a plan view. As used herein, a plan view may refer to a view viewed from a direction perpendicular or substantially perpendicular (e.g., or orthogonal) to the top surface of the associated component, element, layer, area, and / or region, etc. (e.g., the top surface of display 1). When a rectangular shape is applied as the planar shape of display 1 (e.g., the shape when viewed from a plan view), display 1 may include a plurality of long side edges extending along a first direction DR1 and a plurality of short side edges extending along a second direction DR2 intersecting the first direction DR1. The corners where the long side edges connect (e.g., touch or intersect) with the short side edges may have, for example, a rectangular shape. Figure 1 The angular shape shown is not limited to this, and one or more of the corners may have a rounded shape. However, the present disclosure is not limited to a rectangular shape as the planar shape of the display 1, and in some embodiments, the planar shape of the display 1 may include any suitable or desired shape, such as a square shape, a circular shape, an elliptical shape and / or other polygonal shapes.

[0068] In a plan view, display 1 may include: a display area DA, located at the center of display 1 (e.g., in or on the center of display 1); and a non-display area NA, located around the display area DA (e.g., in or on the periphery of the display area DA). For example, in some embodiments, the non-display area NA may surround the display area DA (e.g., around the periphery of the display area DA). The non-display area NA may be a border area where no image is displayed. The display area DA may be an area comprising multiple pixels and displaying an image.

[0069] The planar shape of the display area DA (e.g., the shape when viewed from a plan view) may be the same as or substantially the same as the shape of the display 1 (e.g., planar shape) (e.g., generally equal to or substantially similar to the shape of the display 1). In other words, in an embodiment, the planar shape of the display area DA may be a rectangular shape with angular corners. In this case, the non-display area NA may be positioned (e.g., continuously positioned) along each of the plurality of long and short edges of the display area DA at the edge region (e.g., border region) of the display 1, but this disclosure is not limited thereto. For example, in various embodiments, the non-display area NA may be provided along only one long edge, one short edge, one long edge and one short edge, two long edges and / or two short edges of the display 1 (e.g., provided in only one long edge, one short edge, one long edge and one short edge, two long edges and / or two short edges of the display 1, or provided on only one long edge, one short edge, one long edge and one short edge, two long edges and / or two short edges of the display 1).

[0070] The display 1 includes a display panel 100 and a cover window 600 disposed on the display panel 100 to cover and protect the display panel 100. The display panel 100 may include a display member 200, a viewing angle control member 300 disposed on the display member 200, a touch member 400 disposed on the viewing angle control member 300, and an optical film 500 disposed on the touch member 400.

[0071] The touch component 400 and the optical film 500 can be bonded to each other via a first optically transparent adhesive component AM1 disposed therebetween, and the optical film 500 and the cover window 600 can be bonded to each other via a second optically transparent adhesive component AM2 disposed therebetween. In other words, the first optically transparent adhesive component AM1 can connect the touch component 400 and the optical film 500 to each other (e.g., or attach the touch component 400 and the optical film 500 to each other), and the second optically transparent adhesive component AM2 can connect the optical film 500 and the cover window 600 to each other (e.g., or attach the optical film 500 and the cover window 600 to each other). Each of the first optically transparent adhesive component AM1 and the second optically transparent adhesive component AM2 may include an optically transparent adhesive film, an optically transparent adhesive tape, and / or an optically transparent resin, etc.

[0072] Display panel 100 is a panel that displays an image based on an input data signal. For example, in an embodiment, display panel 100 may include an organic light-emitting display panel. However, although the organic light-emitting display panel is described as a non-limiting example of display panel 100 in the following embodiments, this disclosure is not limited thereto, and as those skilled in the art will appreciate, any other suitable type of display panel (such as liquid crystal display (LCD) panels, quantum dot organic light-emitting diode (QD-OLED) display panels, QD-LCD panels, quantum nano-light-emitting diode (LED) panels, and / or micro LED panels, etc.) may be used as display panel 100.

[0073] The display area DA of the display component 200 includes multiple pixels. Each pixel may include a light-emitting layer and a circuit layer for controlling the amount of light emitted by the light-emitting layer. The circuit layer may include display wiring, display electrodes, and at least one transistor. The light-emitting layer may include an organic light-emitting material. The light-emitting layer may be sealed by an encapsulation film. The encapsulation film can prevent or substantially prevent moisture or other substances from penetrating (e.g., flowing in from the outside) into the light-emitting layer by sealing the light-emitting layer. The encapsulation film may include a single-layer inorganic film or a multi ... organic film, which is formed by alternately stacking inorganic films and organic films.

[0074] The non-display area NA of the display component 200 may include drive wiring connected to the display wiring of the pixels and pads (or “solder pads”) for the drive wiring (e.g., drive wiring pads). As described in more detail below, one or more external components (such as driver chips and / or printed circuit boards (PCBs) may be mounted on the drive wiring pads.

[0075] The thin-film encapsulation layer 270 may be disposed on the upper part of the display member 200 (e.g., on the uppermost part of the display member 200). For example, the thin-film encapsulation layer 270 may be disposed on the light-emitting element of the display member 200 and may cover the light-emitting element. The thin-film encapsulation layer 270 may include (or may be) a laminated film formed by alternately stacking inorganic and organic films. For example, the thin-film encapsulation layer 270 may include a first inorganic encapsulation film 271 (see reference) stacked sequentially. Figure 5 ), organic encapsulation film 272 (reference) Figure 5 ) and the second inorganic encapsulation film 273 (refer to) Figure 5 ).

[0076] In the following text, the components of display component 200 other than the thin film encapsulation layer 270 may be referred to as the lower display component DM.

[0077] A more detailed description of the display component 200 will be given below.

[0078] Touch member 400 may be disposed on display member 200. Touch member 400 may sense touch pressure. Touch member 400 may be disposed inside display panel 100 in the form of a touch layer. However, this disclosure is not limited thereto, and although the following embodiments are described by way of example in which touch member 400 is disposed inside display panel 100, as those skilled in the art will understand, touch member 400 may be disposed as a separate panel or film and attached to display panel 100.

[0079] A more detailed description of the touch component 400 will be given below.

[0080] Optical film 500 may be disposed on touch member 400. Optical film 500 may include multiple laminated films. For example, optical film 500 may include a lower protective film disposed on touch member 400, a phase retardation film disposed on the lower protective film, a polarization layer disposed on the phase retardation film, and an upper protective film disposed on the polarization layer.

[0081] The upper and lower protective films protect the polarization layer and phase retardation film from external moisture and / or foreign substances. The upper and lower protective films may include organic insulating materials.

[0082] Phase retardation films can shift the phase of light. For example, a phase retardation film may include (or may be) a λ / 4 (e.g., quarter-wavelength) phase retardation film. Phase retardation films may include birefringent films containing polymers, alignment films of liquid polymers, and / or films containing alignment layers of liquid polymers, etc.

[0083] The polarizing layer can selectively transmit light. For example, the polarizing layer may include (or may be) a linear polarizing layer. The polarizing layer may include (or may be) a polyvinyl alcohol (PVA) film. The polarizing layer can be manufactured by elongating the PVA film in a desired direction (e.g., in one direction or in the elongation direction) and then adsorbing iodine (I) and / or dichroic dyes therein. In this case, the polarizing layer may have an absorption axis in the elongation direction and a transmission axis in a direction perpendicular or substantially perpendicular (or orthogonal) to the absorption axis. Therefore, linearly polarized light (e.g., only linearly polarized light) incident on the polarizing layer is emitted in a direction parallel or substantially parallel to the transmission axis.

[0084] A cover window 600 is disposed above the display panel 100 (e.g., on the display panel 100). The cover window 600 is disposed above the display panel 100 to protect the display panel 100 while transmitting light emitted from the display panel 100. The cover window 600 may include glass or the like.

[0085] The cover window 600 may be configured to overlap with the display panel 100 and may cover the entire surface of the display panel 100. In some embodiments, the cover window 600 may be larger than the display panel 100. For example, in some embodiments, the cover window 600 may protrude further outward from the two short sides of the display 1 than the display panel 100.

[0086] The viewing angle control component 300 can be positioned between the display component 200 and the touch component 400. For example... Figure 3 As shown, the viewing angle control member 300 may include a light-transmitting pattern 310 and a viewing angle control pattern 350 disposed between adjacent light-transmitting patterns 310 in the light-transmitting pattern 310.

[0087] The translucent pattern 310 can transmit light emitted by the light-emitting element to allow the user to perceive the light. The translucent pattern 310 may include a transparent material. The transparent material may include, for example, a resin and / or a transparent photosensitive material. The resin may include, for example, polyethylene terephthalate (PET), polyacrylate, polyimide (PI), and / or polycarbonate (PC). The transparent photosensitive material may include (or may be), for example, a photoresist. According to an embodiment, the translucent pattern 310 may include a photoresist.

[0088] The viewing angle control pattern 350 can adjust the viewing angle (e.g., a specific viewing angle) to prevent or substantially prevent light emitted by the light-emitting element from being emitted at an angle larger than a desired angle (e.g., a specific angle or a threshold angle) that can be identified by the user. For example, the viewing angle control pattern 350 can adjust the viewing angle (e.g., a specific viewing angle) by reflecting a first ray L1 emitted from the light-emitting element. The viewing angle control pattern 350 may include light-blocking materials and / or reflective materials. Light-blocking materials may include a variety of suitable materials, such as dark pigments (e.g., black and / or gray pigments), dark dyes (e.g., black and / or gray dyes), carbon black, and / or photoresists. Reflective materials may include a variety of suitable materials, such as metallic materials (e.g., aluminum (Al) and / or silver (Ag)).

[0089] Each pixel of display 1 may include a light-emitting area PA and a non-emitting area PB, wherein the non-emitting area PB is located at the periphery of the light-emitting area PA (e.g., on the periphery of the light-emitting area PA) (e.g., or adjacent to the light-emitting area PA). The light-emitting area PA and the non-emitting area PB may be divided by a light-blocking member 610, which will be described in more detail below. The light-blocking member 610 may be disposed on the bottom surface of the cover window 600.

The spaced-apart first touch bridge electrodes CP1 may partially expose the top surface of the first touch insulating layer 410. The first touch bridge electrodes CP1 of the first touch conductive layer 420 may be stacked with a black matrix and a pixel defining film PDL.

The region divided by the plurality of second sensing lines SPL2 may also be superimposed with light-emitting regions LA1, LA2, and LA3 disposed at each pixel (e.g., in or on each pixel). In an embodiment, the region divided by the plurality of first sensing lines SPL1 and the region divided by the plurality of second sensing lines SPL2 may have a rhombus shape. As used herein, taking into account the processing and / or the arrangement shape of the sensing lines, a rhombus shape includes not only shapes that are the same as or substantially the same as a rhombus shape, but also shapes that are similar to a rhombus shape.

[0122] Multiple first sensing lines SPL1 can be electrically insulated from multiple second sensing lines SPL2. In an embodiment, the multiple first sensing lines SPL1 and multiple second sensing lines SPL2 can be disposed in the same or substantially the same layer (e.g., on the same or substantially the same layer). In this case, multiple first touch bridge electrodes CP1 and multiple second touch bridge electrodes CP2 are disposed in different layers from each other (e.g., on different layers from each other) and can be electrically insulated from each other.

[0123] The second touch bridge electrode CP2 and the sensing electrode of the second touch conductive layer 440 can be stacked with the black matrix and the pixel defining film PDL. Therefore, it is possible to prevent or substantially prevent the user from recognizing the second touch bridge electrode CP2 and the sensing electrode.

[0124] The third touch insulating layer 450 may be disposed on the second touch conductive layer 440. The third touch insulating layer 450 may include inorganic or organic materials.

[0125] In some embodiments, the electrodes included in the first touch conductive layer 420 and the electrodes included in the second touch conductive layer 440 may be opposite each other.

[0126] In some embodiments, the first touch conductive layer 420 may include first sensing electrodes IE1_1 to IE1_8 and a first touch bridge electrode CP1, and the second touch conductive layer 440 may include second sensing electrodes IE2_1 to IE2_4 and a second touch bridge electrode CP2.

[0128] For convenience, the following can be mainly described below: The first touch conductive layer 420 includes a first touch bridge electrode CP1 that electrically connects adjacent first sensing electrodes among the first sensing electrodes IE1_1 to IE1_8 to each other; the second touch conductive layer 440 includes a plurality of first sensing electrodes IE1_1 to IE1_8, a plurality of second sensing electrodes IE2_1 to IE2_4, and a second touch bridge electrode CP2 that electrically connects adjacent second sensing electrodes among the second sensing electrodes IE2_1 to IE2_4 to each other.

For example, the conductive material may include a low-resistance metal (such as Ag, Al, Cr and / or Ni, etc.), or the conductive material may include conductive nanomaterials (such as silver nanowires and / or carbon nanotubes, etc.).

[0130] Reference Figure 7 The viewing angle control pattern 350 can have a conical shape. In other words, the viewing angle control pattern 350 can have a trapezoidal shape, wherein the width of the base surface of the trapezoidal shape is greater than the width of its top surface.

[0131] The top surface of the viewing angle control pattern 350 may be aligned with the top surface of the light-transmitting pattern 310. However, this disclosure is not limited thereto; the top surface of the viewing angle control pattern 350 may protrude upward from the top surface of the light-transmitting pattern 310, or may be recessed downward from the top surface of the light-transmitting pattern 310 (e.g., or may be lower than the top surface of the light-transmitting pattern 310). The top surface of the viewing angle control pattern 350 may have a linear shape.

[0133] The height h of the viewing angle control pattern 350 can be equal to or substantially equal to approximately two or three times the pitch P of the viewing angle control pattern 350. When the viewing angle control pattern 350 has a conical shape, the first tilt angle θ1 formed between the side surface of the viewing angle control pattern 350 and the top surface of the thin film encapsulation layer 270 can be an obtuse angle. For example, the first tilt angle θ1 can be equal to or substantially equal to approximately 91° to approximately 110°.

[0134] The height h of the viewing angle control pattern 350 can be larger than the first width W1 of the luminous areas LA1, LA2 and LA3 of each pixel.

[0135] In the display 1 according to the embodiment, since the viewing angle control member 300 including the viewing angle control pattern 350 is embedded in the display panel 100, the distance between the light-emitting element ED of each of the pixels PX1, PX2 and PX3 and the viewing angle control pattern 350 can be reduced, thereby adjusting (e.g., adjusting more easily) the viewing angle.

[0136] Furthermore, since the viewing angle control member 300 is disposed on the top surface of the thin film encapsulation layer 270 of the display panel 100 (for example, directly disposed on the top surface of the thin film encapsulation layer 270 of the display panel 100) without the use of adhesives or the like, the transmission loss of light emitted by the light-emitting element ED of the display panel 100 can be prevented or substantially prevented in advance.

[0137] Furthermore, the viewing angle control pattern 350 of the viewing angle control member 300 can be arranged so that it does not overlap with the light emission areas LA1, LA2 and LA3 of the adjacent pixels PX1, PX2 and PX3, thereby preventing or substantially preventing light loss in advance.

[0141] When the viewing angle control pattern 350_1 has an inverted conical shape, a second tilt angle θ2 can be formed between the side surface of the viewing angle control pattern 350_1 and the top surface of the thin film encapsulation layer 270. In this case, the second tilt angle θ2 can be an acute angle. For example, the second tilt angle θ2 can be equal to or substantially equal to approximately 85° to approximately 89°.

The resin may include, for example, PET, polyacrylate, PI, and / or PC. The transparent photosensitive material may include, for example, a photoresist.

[0166] Then, the light-transmitting material 310b_1 in the area where the mask M is not positioned is developed and removed, and the light-transmitting material 310a in the area where the mask M is positioned is baked, so that it can form Figure 18 The light-transmitting pattern 310c_1 has an opening formed in it, allowing the top surface of the thin-film encapsulation layer 270 to be exposed. The light-transmitting pattern 310c_1 can be combined with the above-mentioned...
