Description

[0001] This application claims priority to and all benefits derived therefrom of Korean Patent Application No. 10-2024-0043080, filed on March 29, 2024, the contents of which are incorporated herein by reference in their entirety. Technical Field

[0002] This disclosure relates to display devices. Background Technology

[0003] With the development of an information-driven society, the demand for display devices is constantly increasing. Display devices can be liquid crystal displays, field emission displays, or light-emitting displays, etc. Light-emitting displays can include organic light-emitting displays that use organic light-emitting diodes as light-emitting elements, and inorganic light-emitting displays that use inorganic light-emitting diodes as light-emitting elements, etc.

[0004] For vehicles equipped with display devices, images displayed on the display device positioned in front of the driver or passenger may be projected onto the windshield at night. When this occurs, such images may obstruct the driver's view. Accordingly, it is desirable to control the viewing angle of the images displayed on the vehicle's display device. Furthermore, to protect privacy, it is desirable to control the viewing angle of the images displayed on the vehicle's display device so that the images displayed on the display device positioned in front of the driver are not seen by passengers.

[0042] Embodiments of the present disclosure will now be described more fully below with reference to the accompanying drawings, in which preferred embodiments of the invention are illustrated. However, the invention may be embodied in various forms and 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 scope of the invention to those skilled in the art.

[0043] It will also be understood that when a layer is referred to as being "on" another layer or substrate, it can be directly on that other layer or substrate, or an intervening layer may be present. Throughout the specification, the same reference numerals indicate the same parts.

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

[0045] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used herein, unless the context clearly indicates otherwise, the singular forms “a” and “the (described)” are intended to include the plural forms, which include “at least one”. “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, when used in this specification, the terms “comprising” or “including” and / or variations thereof indicate the presence of stated features, areas, integrals, steps, operations, elements, and / or components, but do not preclude 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 as illustrated in the accompanying drawings. It will be understood that, in addition to the orientations depicted in the drawings, relative terms are intended to include different orientations of the device. For example, if the device in one of the drawings is flipped, an element described as being “below” the other element will then be oriented “above” that other element. Thus, depending on the specific orientation of the drawing, the exemplary term “below” may encompass both “below” and “above” orientations. Similarly, if the device in one of the drawings is flipped, an element described as being “below” or “under” the other element will then be oriented “above” the other element. Thus, the exemplary terms “below” or “under” may include both “above” and “below” orientations.

[0047] Given the measurements discussed and the errors associated with the measurement of a particular quantity (i.e., limitations of the measurement system), the terms “approximately” or “about” as used herein include stated values ​​and mean within an acceptable range of deviation from that particular value as determined by one of ordinary skill in the art. For example, a term such as “approximately” may mean within one or more standard deviations, or within ±30%, ±20%, ±10%, ±5% of said value.

[0048] 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 (such as those defined in common dictionaries) shall be interpreted as having the same meaning as they have in the context of the relevant art and this disclosure, and shall not be interpreted in an idealized or overly formal sense unless expressly defined herein.

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

[0050] Figure 1 This is a perspective view illustrating an embodiment of a display device according to the present disclosure. Figure 2 This is a plan view illustrating an embodiment of a display device according to the present disclosure.

[0051] Reference Figures 1 to 2The display device 10 is used to display moving or still images. The display device 10 can be used as a display screen for portable electronic devices such as mobile phones, smartphones, tablet PCs (“PCs”), smartwatches, watch phones, mobile communication terminals, e-notebooks, e-books, portable multimedia players (“PMPs”), navigation devices, and ultra-mobile PCs (“UMPCs”), as well as for various products such as automobiles, televisions, laptops, monitors, billboards, and Internet of Things (“IoT”) devices.

[0052] In some embodiments where the display device 10 is used as a display screen for a vehicle, the display device 10 may be an in-vehicle display. An in-vehicle display can provide users with various service information such as convenience features and media information, as well as vehicle driving information and status information. When the display device 10 includes an input device such as a touch panel, the user can manipulate various features such as the vehicle's driving mode and convenience features through the display device 10.

[0053] Display device 10 may be one of organic light-emitting display devices, liquid crystal display devices, plasma display devices, field emission display devices, electrophoretic display devices, electrowetting display devices, quantum dot light-emitting display devices, and micro light-emitting diode (“LED”) display devices. In the following description, organic light-emitting display devices are described in embodiments of display device 10. However, it should be understood that this disclosure is not limited thereto.

[0054] In embodiments of this disclosure, the display device 10 may include a display panel 100, a display driving circuit 250, a circuit board 300, and a touch driving circuit 400.

[0055] The display panel 100 may include a plurality of pixels PX disposed in a first direction DR1 and a second direction DR2. When viewed from above, each of the pixels PX may have a quadrilateral shape, such as a rectangle, a square, or a rhombus. In an embodiment, for example, as shown in the accompanying drawings, each of the pixels PX may have a square shape when viewed from above. However, it should be understood that this disclosure is not limited thereto. Each of the pixels PX may have various shapes, such as other polygonal shapes, circular shapes, and elliptical shapes, when viewed from above.

[0056] In the accompanying drawings, the first direction DR1 and the second direction DR2 intersect each other as horizontal directions. In embodiments, for example, the first direction DR1 and the second direction DR2 may be perpendicular to each other. Additionally, for example, the third direction DR3 may intersect the first direction DR1 and the second direction DR2, and may be perpendicular to them. In this document, the side indicated by the arrows of each of the first to third directions DR1, DR2, and DR3 in the accompanying drawings may also be referred to as the first side, and the opposite side may also be referred to as the second side. Unless otherwise stated, each of the first to third directions DR1, DR2, and DR3 may comprise opposite sides. In this document, unless otherwise explicitly stated, the side indicated by the arrows of each of the first to third directions DR1, DR2, and DR3 may also be referred to as the first side, and the opposite side may also be referred to as the second side opposite to the first side. As used herein, the terms "on," "upper side," "above," "top," and "upper surface" refer to the side indicated by the arrow of the third direction DR3 as shown in the accompanying drawings. The terms “below,” “lower side,” “below,” “bottom,” and “lower surface” refer to the opposite side indicated by the arrow pointing from a third party to DR3, as shown in the attached figure.

[0057] The display panel 100 may include a main area MA and a protruding area PA that protrudes from one side of the main area MA.

[0058] The main region MA can be formed as, for example, a quadrilateral shape with a shorter side on a first direction DR1 and a longer side on a second direction DR2 intersecting the first direction DR1. Each of the corners where the shorter side on the first direction DR1 intersects the longer side on the second direction DR2 can be rounded with a predetermined curvature, or can be a right angle. When viewed from above, the shape of the display device 10 is not limited to a quadrilateral shape, but can be formed as other polygonal shapes, circular shapes, or elliptical shapes. The main region MA can be, but is not limited to, being flat. The main region MA may include curved portions formed at its left and right ends. The curved portions can have a constant curvature or a varying curvature.

[0059] The main region MA may include the display region DA, which forms pixels PX to display the image, and the non-display region NDA surrounding the display region DA.

[0060] In addition to the pixel PX, the scan lines, data lines, and power lines connected to the pixel PX can be set in the display area DA. When the main area MA includes a curved portion, the display area DA can be set in the curved portion. In this case, the image of the display panel 100 can also be seen on the curved portion.

[0061] The non-display area NDA can be defined as the area extending from the outer edge of the display area DA to the edge of the display panel 100. Within the non-display area NDA, a scan driver for applying scan signals to scan lines and a connection line for connecting data lines to the display drive circuit 250 can be provided.

[0062] The protruding region PA can protrude from one side of the main region MA. In an embodiment, for example, as... Figure 2 As shown, the protruding region PA can protrude from the lower side of the main region MA. The length of the protruding region PA in the first direction DR1 can be less than the length of the main region MA in the first direction DR1.

[0063] The prominent area PA may include a bending area BA and a pad area PDA. In this case, the pad area PDA may be located on one side of the bending area BA, and the main area MA may be located on the opposite side of the bending area BA. In an embodiment, for example, the pad area PDA may be located below the bending area BA, and the main area MA may be located above the bending area BA.

[0064] The display panel 100 can be flexible, allowing it to be bent, folded, rolled, or bent. Therefore, the display panel 100 can be bent in the third direction DR3 (i.e., the thickness direction) at the bending region BA. In this case, before the display panel 100 is bent, the surface of the pad region PDA of the display panel 100 faces upwards, and after the display panel 100 is bent, the surface of the pad region PDA of the display panel 100 faces downwards. As a result, since the pad region PDA is positioned below the main region MA, it can overlap with the main region MA.

[0065] The pads electrically connected to the display driver circuit 250 and the circuit board 300 can be set in the pad area of ​​the display panel 100 PDA.

[0066] The display driver circuit 250 outputs signals and voltages for driving the display panel 100. In one embodiment, the display driver circuit 250 can apply a data voltage to a data line. Alternatively, for example, the display driver circuit 250 can apply a power supply voltage to a power line and can apply a scan control signal to a scan driver. The display driver circuit 250 can be implemented as an integrated circuit (“IC”) and can be attached to the display panel 100 in the pad area of ​​the PDA using chip-on-glass (“COG”) technology, chip-on-plastic (“COP”) technology, or ultrasonic bonding. In another embodiment, for example, the display driver circuit 250 can be disposed (e.g., mounted) on a circuit board 300.

[0067] The pads may include display pads electrically connected to the display driver circuit 250 and touch pads electrically connected to the touch line.

[0068] The circuit board 300 can be attached to the pads using an anisotropic conductive film. In this way, the leads of the circuit board 300 can be electrically connected to the pads. The circuit board 300 can be a flexible printed circuit board, a rigid printed circuit board, or a flexible film such as a chip-on-film.

[0069] The touch driver circuit 400 can be connected to the touch sensor layer TSU of the display panel 100 (see reference). Figure 3 The touch electrode of the touch sensor layer (TSU). The touch driving circuit 400 applies a driving signal to the touch sensor layer (TSU) (see reference). Figure 3 The touch driving circuit 400 measures the capacitance of the touch electrodes. The driving signal can include driving pulses. The touch driving circuit 400 can not only determine whether a touch has been input based on capacitance, but also calculate the touch coordinates of the position where the touch was input.

[0070] The touch driver circuit 400 can be disposed on the circuit board 300. The touch driver circuit 400 can be implemented as an IC and can be disposed (e.g., mounted) on the circuit board 300.

[0071] According to this embodiment, the display panel 100 of the display device 10 may further include a light control layer (LCL).

[0072] The light control layer LCL can be directly disposed in the main area MA of the display panel 100. In an embodiment, for example, the light control layer LCL can be incorporated into the display panel 100 and can be directly disposed in the main area MA of the display panel 100. Since the light control layer LCL is incorporated into the display panel 100, the thickness and manufacturing cost of the display device 10 can be advantageously reduced compared to a display device in which a separate light control film is attached.

[0073] In some embodiments, the light control layer LCL may be disposed in the display area DA of the main area MA. The light control layer LCL can adjust the emission layer 172 (see reference) of the display panel 100. Figure 5 The angle of the emitted light.

[0074] However, it should be understood that the embodiments disclosed herein are not limited thereto. When viewed from above, the size of the light control layer LCL can be larger than the size of the display area DA. In this case, the light control layer LCL can overlap with both the display area DA and the non-display area NDA.

[0075] In some embodiments, the light control layer LCL may include an open area OA and a light-shielding area LSA.

[0076] In the open area (OA), a light-shielding film (LS) may not be required (see reference). Figure 6The open region OA can transmit light and can extend along the first direction DR1. (e.g.) Figure 1 and Figure 2 As shown, when viewed from above, the open area OA can have a quadrilateral shape, such as a rectangle, but this disclosure is not limited thereto. When viewed from above, the open area OA can also have a circular shape, an elliptical shape, or other polygonal shapes. In some embodiments, the shape of the open area OA may generally follow the shape of the display panel 100.

[0077] The light-shielding area LSA can be the remaining area of ​​the light control layer LCL, excluding the open area OA. A light-shielding film LS can be installed within the light-shielding area LSA (see reference). Figure 6 ).

[0078] In some embodiments, the light-shielding region LSA may extend along either the first direction DR1 or the second direction DR2. In embodiments, for example, as... Figure 1 As shown, the light-shielding region LSA may extend in the first direction DR1 and be arranged in the second direction DR2. In another embodiment, the light-shielding region LSA may extend in the second direction DR2 and be arranged in the first direction DR1. In yet another embodiment, some of the light-shielding regions LSA may extend in the first direction DR1 and be arranged in the second direction DR2, while others of the light-shielding regions LSA may extend in the second direction DR2 and be arranged in the first direction DR1.

[0079] According to the arrangement of the shading area LSA on the second direction DR2. Figure 1 In one embodiment, the viewing angle can be controlled in the second direction DR2. In another embodiment, in which the light-shielding region LSA is arranged in the first direction DR1, the viewing angle can be controlled in the first direction DR1. In the display device 10 according to this embodiment, the arrangement and shape of the open region OA and the light-shielding region LSA can be changed in various ways depending on the desired viewing angle control direction.

[0080] Although the open area OA surrounds the light-shielding area LSA in the accompanying drawings, this disclosure is not limited thereto. In some embodiments, the open area OA may include multiple open areas OA, and the multiple open areas OA may extend in the same direction as the light-shielding area LSA, such that the open areas OA and the light-shielding area LSA can be alternately arranged. In embodiments, for example, when such... Figure 1 As shown, when the light-shielding area LSA extends in the first direction DR1, multiple open areas OA can extend in the first direction DR1 and can be alternately set with the light-shielding area LSA in the second direction DR2.

[0081] The light control layer LCL may include an emission layer 172 (see reference) that blocks light from emitting from the display panel 100. Figure 5 The light-shielding film LS (reference) emits light. Figure 6 ) and the light-transmitting film LT (refer to) Figure 6 (See below for reference) Figure 6 The structure of the light control layer LCL is described in detail.

[0082] Figure 3 It is along Figure 2 A cross-sectional view of the display device taken by line X1-X1'.

[0083] Reference Figure 3 The display device 10 may include a display panel 100 in which a light control layer LCL is incorporated. The display panel 100 may include a substrate BS, a thin film transistor layer TFTL, an emissive material layer EML, a thin film encapsulation layer TFEL, a touch sensor layer TSU, and a light control layer LCL.

[0084] The substrate component BS may include a substrate. The substrate may include, or be composed of, an insulating material such as glass, quartz, and polymeric resin. In embodiments, the polymeric material may include polyethersulfone (“PES”), polyacrylate (“PA”), polyarylate (“PAR”), polyetherimide (“PEI”), polyethylene naphthalate (“PEN”), polyethylene terephthalate (“PET”), polyphenylene sulfide (“PPS”), polyallyl ester, polyimide (“PI”), polycarbonate, cellulose triacetate (“CAT”), cellulose acetate propionate (“CAP”), or any combination thereof. In alternative embodiments, the substrate may include a metallic material.

[0085] The substrate can be a rigid substrate or a flexible substrate that can be bent, folded, rolled, etc. When the substrate is a flexible substrate, it can include or be composed of PI, but is not limited to PI.

[0086] A thin-film transistor layer (TFTL) can be disposed on a substrate component (BS). Within the TFTL, scan lines, data lines, power supply lines, scan control lines, transmission lines connecting pads to data lines, and thin-film transistors in pixels (PX) can be formed. Each thin-film transistor may include a gate electrode, a semiconductor layer, a source electrode, and a drain electrode.

[0087] The thin-film transistor layer (TFTL) can be disposed in the display area (DA) and the non-display area (NDA). Specifically, the scan lines, data lines, power supply lines, and thin-film transistors in the pixels (PX) of the TFTL can be disposed in the display area (DA). The scan control lines and connection lines of the TFTL can be disposed in the non-display area (NDA).

[0088] An emissive material layer (EML) can be disposed on a thin-film transistor layer (TFTL). The EML (also known as the light-emitting element layer) can include light-emitting elements, each comprising a first light-emitting electrode, an emissive layer, and a second light-emitting electrode, as well as a diaphragm. The emissive layer can be an organic emissive layer comprising or composed of organic materials. The emissive layer can then include a hole transport layer, an organic light-emitting layer, and an electron transport layer. When an anode voltage is applied to the first light-emitting electrode and a cathode voltage is applied to the second light-emitting electrode through the thin-film transistors in the TFTL, holes and electrons move to the organic light-emitting layer through the hole transport layer and electron transport layer, respectively, causing them to recombine in the organic light-emitting layer to emit light. The EML can be disposed in the display area (DA).

[0089] A thin-film encapsulation layer (TFEL) can be disposed on the emitter material layer (EML). The TFEL prevents oxygen or moisture from penetrating into the EML. For this purpose, the TFEL may include at least one inorganic layer. The inorganic layer may be, but is not limited to, a silicon nitride layer, a silicon oxynitride layer, a silicon oxide layer, a titanium oxide layer, or an aluminum oxide layer. Additionally, the TFEL protects the EML from foreign matter such as dust. For this purpose, the TFEL may include at least one organic layer. The organic layer may include, but is not limited to, acrylic resin, epoxy resin, phenolic resin, polyamide resin, and PI resin, or a mixture thereof.

[0090] The thin-film encapsulation layer TFEL can be disposed in both the display area DA and the non-display area NDA. Specifically, the thin-film encapsulation layer TFEL can cover the emitter material layer EML in the display area DA, and can cover the thin-film transistor layer TFTL in the non-display area NDA.

[0091] The touch sensor layer TSU can be disposed on the thin film encapsulation layer TFEL. Since the touch sensor layer TSU is disposed directly on the thin film encapsulation layer TFEL, the thickness of the display device 10 can be reduced compared to a display device in which a separate touch panel including the touch sensor layer TSU is attached to the thin film encapsulation layer TFEL.

[0092] The touch sensor layer (TSU) may include touch electrodes for sensing a user's touch via capacitive sensing and touch lines for connecting pads to the touch electrodes. In embodiments, for example, the touch sensor layer (TSU) may sense a user's touch via self-capacitance sensing or mutual capacitance sensing.

[0093] The touch electrodes of the touch sensor layer (TSU) can be located in the touch sensor area that overlaps with the display area (DA). The touch lines of the touch sensor layer (TSU) can be located in the touch periphery area that overlaps with the non-display area (NDA).

[0094] The light control layer (LCL) can be disposed on the touch sensor layer (TSU). The light control layer (LCL) can be configured to overlap with the display area (DA). The light control layer (LCL) can absorb or block some of the light emitted from the emissive material layer (EML) that propagates outside a predetermined angle relative to the third direction (DR3). In other words, the light control layer (LCL) can control the viewing angle.

[0095] Although not shown in the accompanying drawings, the display device 10 may further include a cover window. The cover window may be further disposed on the light control layer LCL. The light control layer LCL and the cover window may be attached together by a transparent adhesive member such as an optically clear adhesive (“OCA”) film.

[0096] Figure 4 This is a view schematically illustrating an embodiment of a display device applied to a vehicle.

[0097] Reference Figure 4 For example, the display device 10 in the embodiments can be applied to a vehicle. The vehicle may include a body forming the exterior of the vehicle and an interior space defined by the body. The body may include a windshield W that protects the driver PS1 and passenger PS2 from external influences and allows the driver PS1 to see the exterior of the vehicle through it. As shown in the figures, the display device 10 can be provided within the interior space.

[0098] In some embodiments, the display device 10 may be placed on a dashboard provided within the interior space. In embodiments, for example, such as... Figure 4 As shown, the display device 10 can extend from the dashboard located in front of the driver's seat to the dashboard located in front of the passenger seat. In an embodiment, for example, the display device 10 may be a single large display connected from the dashboard located in front of the driver's seat to the dashboard located in front of the passenger seat.

[0099] In this configuration, the display device 10 may include a first display area DA1 disposed in front of the driver's seat and a second display area DA2 disposed in front of the passenger's seat. The first display area DA1 may be placed on the dashboard in front of the driver's seat and may provide speed information, etc., to the driver PS1, while the second display area DA2 may be placed on the dashboard in front of the passenger's seat and may provide entertainment information, etc., to the passenger PS2. Although not shown in the accompanying drawings, a third display area may be further included between the first display area DA1 and the second display area DA2.

[0100] In another embodiment, the display device 10 may be placed on each of the dashboard in front of the driver's seat and the dashboard in front of the passenger seat. In an embodiment, for example, a first display device may be placed on the dashboard in front of the driver's seat, and a second display device may be placed on the dashboard in front of the passenger seat.

[0101] The driver PS1 can identify (or see) the image on the display screen of the display device 10 by the light LGT0_1 emitted from the display device 10 in front of the driver's seat toward the driver PS1. A predetermined portion of the light LGT1 emitted from the display device 10 in front of the driver's seat may be reflected from the windshield W and provided to the driver PS1. When this occurs, the image projected onto the windshield W may obstruct the driver PS1's view. Conversely, in the display device 10 of the embodiment, by adjusting the viewing angle (especially the vertical viewing angle) of the front side (the side facing the driver PS1) of the light emitted from the display device 10, it is possible to prevent the predetermined light LGT1 emitted from the display device 10 in front of the driver's seat from being reflected from the windshield W and provided to the driver PS1.

[0102] Passenger PS2 can recognize (or see) the image on the display screen of display device 10 by the light LGT0_2 emitted from display device 10 in front of passenger seat toward passenger PS2. It should be noted that the predetermined light LGT2 emitted from display device 10 in front of passenger seat can be directed toward driver PS1. When this occurs, for reasons such as driving safety, driver PS1's view of display device 10 can be restricted. In the embodiment of display device 10, by adjusting the viewing angle (especially the horizontal viewing angle) of the front side (the side facing passenger PS2) of the light emitted from display device 10, it is possible to prevent the predetermined light LGT2 emitted from display device 10 in front of passenger seat from being provided to driver PS1.

[0103] Although the vertical viewing angle of the display device 10 in front of the driver's seat and the horizontal viewing angle of the display device 10 in front of the passenger seat are adjusted in the accompanying drawings, this disclosure is not limited thereto. In embodiments, for example, the horizontal viewing angle of the display device 10 in front of the driver's seat can be adjusted, while the vertical viewing angle of the display device 10 in front of the passenger seat can be adjusted. In another embodiment, the vertical and horizontal viewing angles of each of the display devices 10 in front of the driver's seat and the display devices 10 in front of the passenger seat can be adjusted.

[0104] The viewing angle can be adjusted by the light control layer (LCL). The viewing angle can be limited to a predetermined angular range by the light control layer (LCL). In embodiments, for example, the viewing angle relative to the normal can be equal to or less than 35°, where the normal is an imaginary line extending in a direction perpendicular to the display surface of the display device 10 and facing the driver PS1 or passenger PS2. In some embodiments, an angle equal to or less than 35° relative to the normal can be defined as an effective viewing angle, but this disclosure is not limited thereto.

[0110] The first buffer film BF1 is a film used to protect the first thin-film transistor ST1 and the emitter layer 172 from moisture that permeates through the first substrate SUB1 and the second substrate SUB2, which are susceptible to moisture penetration. The first buffer film BF1 may be composed of multiple inorganic films (also referred to as inorganic layers) stacked alternately on top of each other. In embodiments, for example, the first buffer film BF1 may be composed of a multilayer film in which multiple inorganic films of silicon nitride layer, silicon oxynitride layer, silicon oxide layer, titanium oxide layer and aluminum oxide layer are stacked alternately on top of each other, or a single layer of one of the inorganic films of silicon nitride layer, silicon oxynitride layer, silicon oxide layer, titanium oxide layer and aluminum oxide layer.

The second buffer film BF2 is a film used to protect the first thin-film transistor ST1 and the emitter layer 172 from moisture that permeates through the first substrate SUB1 and the second substrate SUB2, which are susceptible to moisture penetration. The second buffer film BF2 can be composed of multiple inorganic layers stacked alternately on top of each other. In embodiments, for example, the second buffer film BF2 can be composed of a multilayer in which multiple inorganic layers selected from silicon nitride, silicon oxynitride, silicon oxide, titanium oxide, and aluminum oxide are stacked alternately on top of each other, or a single layer of one of the inorganic layers selected from silicon nitride, silicon oxynitride, silicon oxide, titanium oxide, and aluminum oxide.

[0114] The first active layer ACT1 of the first thin-film transistor ST1 can be disposed on the second buffer film (also referred to as the second buffer layer) BF2. The first active layer ACT1 of the first thin-film transistor ST1 includes polycrystalline silicon (e.g., low-temperature polycrystalline silicon), monocrystalline silicon, amorphous silicon, or oxide semiconductor. Since the portions of the first active layer ACT1 of the first thin-film transistor ST1 that are not covered by the first gate insulator (also referred to as the first gate insulating layer) GI1 but are exposed are doped with impurities or ions, these portions can be conductive. Therefore, the first source electrode TS1 and the first drain electrode TD1 of the first active layer ACT1 of the first thin-film transistor ST1 can be formed.

The first capacitor electrode CAE1 can overlap with the first gate electrode TG1 of the first thin film transistor ST1 on the third-direction DR3. Since the first intermediate dielectric layer 141 has a predetermined dielectric constant, the capacitor can be formed by the first capacitor electrode CAE1, the first gate electrode TG1, and the first intermediate dielectric layer 141 disposed therebetween. The first capacitor electrode CAE1 can be composed of a single layer or multiple layers of one of molybdenum (Mo), aluminum (Al), chromium (Cr), gold (Au), titanium (Ti), nickel (Ni), neodymium (Nd), and copper (Cu) or any alloy thereof.

The first anode connection electrode ANDE1 can be composed of a single layer or multiple layers of one of molybdenum (Mo), aluminum (Al), chromium (Cr), gold (Au), titanium (Ti), nickel (Ni), neodymium (Nd) and copper (Cu) or any alloy thereof.

[0150] In some embodiments, the plurality of transmission regions EA may include a first transmission region EA1, a second transmission region EA2, and a third transmission region EA3. Although three types of transmission regions EA are included in the display area DA in the figures, this disclosure is not limited thereto. More or fewer types of transmission regions EA may be included.

[0151] The first emitting region EA1 can emit light of a first color, the second emitting region EA2 can emit light of a second color, and the third emitting region EA3 can emit light of a third color. The first color light can be light in the red wavelength range, the second color light can be light in the green wavelength range, and the third color light can be light in the blue wavelength range.

[0155] exist Figure 6 In the example shown, like Figure 1 Like the display device 10 in the embodiment, the open area OA and the light-shielding area LSA extend in the first direction DR1.

[0156] The emission area EA of the display area DA can overlap with the open area OA and the light-shielding area LSA on the third-direction DR3. In an embodiment, for example, the first to third emission areas EA1, EA2 and EA3 can overlap with the open area OA and the light-shielding area LSA.

In an embodiment, when the light emitted from the emission layer (DR3) propagates at a predetermined angle or smaller relative to the third direction (DR3), the light can be emitted to the outside. When the light emitted from the emission layer (DR3) propagates beyond the predetermined angle relative to the third direction (DR3), the light can be absorbed or blocked by the light-shielding film (LS) and cannot be emitted to the outside.

[0159] The light control layer LCL may include an intermediate layer OLD, a bottom light-transmitting film OPVX, a light-transmitting film LT, and a light-shielding film LS.

[0161] An intermediate OLD layer can be disposed between the bottom transparent OPVX and the organic film to enhance interfacial properties, allowing the bottom transparent OPVX to be easily deposited onto the organic film during the deposition process. In an embodiment, for example, when the bottom transparent OPVX is directly deposited on an organic film with interfacial properties different from those of the bottom transparent OPVX, the deposited particles may not easily deposit on the organic film. Conversely, when the intermediate OLD layer is disposed on the organic film, the deposited particles of the bottom transparent OPVX can be easily deposited on the intermediate OLD layer.

[0162] A bottom light-transmitting film OPVX can be disposed on the intermediate OLD layer. The bottom light-transmitting film OPVX can transmit light emitted from the emitting layer 172. The bottom light-transmitting film OPVX can include a transparent organic material. In embodiments, for example, the bottom light-transmitting film OPVX can include an organic film such as acrylic resin, epoxy resin, phenolic resin, polyamide resin, and PI resin.

In embodiments, for example, the light-transmitting film LT may comprise an organic film such as acrylic resin, epoxy resin, phenolic resin, polyamide resin, and PI resin.

[0164] The light-transmitting membrane LT can be installed in the open area OA. For example... Figure 6 As shown, the light-transmitting film LT can be alternately disposed with the light-shielding film LS in the second direction DR2. In another embodiment, the light-transmitting film LT can be alternately disposed with the light-shielding film LS in the first direction DR1.

[0165] The light-shielding film LS can absorb or block light emitted from the emitting layer 172. The light-shielding film LS may include light-blocking organic materials. In embodiments, for example, the light-shielding film LS may be a photosensitive resin capable of absorbing or blocking light, and may include organic black pigments such as carbon black or organic materials composed thereof.

[0166] The light-shielding film LS can be placed within the light-shielding area LSA. For example... Figure 6 As shown, the light-shielding film LS can be alternately disposed with the light-transmitting film LT in the second direction DR2. In another embodiment, the light-shielding film LS can be alternately disposed with the light-transmitting film LT in the first direction DR1.

[0167] In some embodiments, the light-transmitting film LT may include a first light-transmitting layer LT_L1, a second light-transmitting layer LT_L2, and a third light-transmitting layer LT_L3. The light-shielding film LS may include a first light-shielding layer LS_L1, a second light-shielding layer LS_L2, and a third light-shielding layer LS_L3.

[0168] The first light-transmitting layer LT_L1 can be disposed on the bottom light-transmitting film OPVX. The first light-shielding layer LS_L1 can be disposed on the first light-transmitting layer LT_L1. The second light-transmitting layer LT_L2 can be disposed on both the first light-shielding layer LS_L1 and the first light-transmitting layer LT_L1. The second light-shielding layer LS_L2 can be disposed on the second light-transmitting layer LT_L2. The third light-transmitting layer LT_L3 can be disposed on both the second light-shielding layer LS_L2 and the second light-transmitting layer LT_L2. The third light-shielding layer LS_L3 can be disposed on the third light-transmitting layer LT_L3.

[0169] Each of the first light-shielding layer LS_L1, the second light-shielding layer LS_L2, and the third light-shielding layer LS_L3 may include a plurality of light-shielding patterns spaced apart from each other in the first direction DR1 or the second direction DR2. In an embodiment, for example, when... Figure 6 As shown, when the light-shielding film LS is spaced apart in the second direction DR2, the multiple light-shielding patterns of each of the first light-shielding layer LS_L1, the second light-shielding layer LS_L2 and the third light-shielding layer LS_L3 can be spaced apart from each other in the second direction DR2.

[0170] The display device 10 may further include an outer coating OC. The outer coating OC may be disposed on the third light-shielding layer LS_L3 and the third light-transmitting layer LT_L3. The outer coating OC may include an organic film such as acrylic resin, epoxy resin, phenolic resin, polyamide resin and PI resin.

[0171] In some embodiments, the light-transmitting film LT can be formed via an inkjet printing process. The bottom light-transmitting film OPVX can be formed via a deposition process or a photolithography process. The light-transmitting film LT may comprise different materials from the bottom light-transmitting film OPVX. In embodiments, for example, the light-transmitting film LT may comprise ester compounds and phosphine oxide compounds. Specifically, the number of carbon atoms in the ester compounds may be equal to or less than 30. The bottom light-transmitting film OPVX may comprise propylene glycol methyl ether acetate, methacrylate-benzyl methacrylate copolymer, polyfunctional acrylates, and photoinitiators.

[0172] In some embodiments, similar to the bottom transparent film OPVX, the outer coating OC can be formed via a deposition process or a photolithography process. Like the bottom transparent film OPVX, the outer coating OC may include propylene glycol methyl ether acetate, methacrylate-benzyl methacrylate copolymer, multifunctional acrylate, and a photoinitiator.

[0173] Figure 8 This is a cross-sectional view showing an embodiment of the display area, non-display area, and protruding area of ​​a display panel.

[0174] Together Figure 1 and Figure 7 Reference Figure 8 The bottom transparent film OPVX and the middle layer OLD can extend not only in the display area DA, but also into the non-display area NDA or the protruding area PA.

[0175] In some embodiments, one end of the intermediate OLD layer may extend further from the display area DA toward the non-display area NDA or the protruding area PA than one end of the bottom light-transmitting film OPVX. That is, the end of the bottom light-transmitting film OPVX may be closer to the display area DA than the end of the intermediate OLD layer. The end of the bottom light-transmitting film OPVX may be closer to the encapsulation dam EDAM, which will be described later, than the end of the intermediate OLD layer.

[0176] The first light-transmitting layer LT_L1, the second light-transmitting layer LT_L2, and the third light-transmitting layer LT_L3 can extend not only into the display area DA, but also into the non-display area NDA or the protruding area PA.

[0177] Although, in the accompanying drawings, multiple light-shielding patterns of each of the first light-shielding layer LS_L1, the second light-shielding layer LS_L2, and the third light-shielding layer LS_L3 are also provided in the non-display area NDA or the protruding area PA, this disclosure is not limited thereto. In embodiments, for example, the multiple light-shielding patterns of each of the first light-shielding layer LS_L1, the second light-shielding layer LS_L2, and the third light-shielding layer LS_L3 may be provided only in the display area DA, and not in the non-display area NDA or the protruding area PA.

[0178] The display panel 100 may further include encapsulated dam EDAM and light-transmitting film dams ODAM1 and ODAM2.

[0179] The encapsulated dam EDAM can be positioned further into the display panel 100 than the transparent film dams ODAM1 and ODAM2. In an embodiment, for example, the encapsulated dam EDAM can be positioned closer to the display area DA than the transparent film dams ODAM1 and ODAM2.

[0180] Although in the accompanying drawings, the encapsulation dam EDAM is disposed in the display area DA and the non-display area NDA, and the light-transmitting film dams ODAM1 and ODAM2 are disposed in the non-display area NDA or the protruding area PA, this disclosure is not limited thereto. In another embodiment, both the encapsulation dam EDAM and the light-transmitting film dams ODAM1 and ODAM2 may be disposed in the non-display area NDA or the protruding area PA, or both may be disposed in the display area DA.

[0181] The encapsulation dam EDAM can be disposed on the substrate member BS. The encapsulation dam EDAM can be disposed below the bottom transparent film OPVX. The encapsulation dam EDAM can prevent the second encapsulation film TFE2 of the thin-film encapsulation layer TFEL from overflowing into or outside the non-display area NDA. Although the display panel 100 includes one encapsulation dam EDAM in the figures, this disclosure is not limited thereto. The display panel 100 may include two or more encapsulation dam EDAMs.

[0182] The encapsulated dam EDAM can have a structure in which multiple layers are stacked on top of each other. In some embodiments, at least one layer of the encapsulated dam EDAM and at least one of the first organic membrane 160, the second organic membrane 180 and the dam 190 may comprise the same material and may be disposed in the same layer.

[0183] The light-transmitting film dams ODAM1 and ODAM2 may be positioned further outward from the display panel 100 than the encapsulation dam EDAM. In an embodiment, for example, the light-transmitting film dams ODAM1 and ODAM2 may be positioned closer to the non-display area NDA or the protruding area PA than the encapsulation dam EDAM. The light-transmitting film dams ODAM1 and ODAM2 may be positioned further outward from the end of the bottom light-transmitting film OPVX. In an embodiment, for example, the light-transmitting film dams ODAM1 and ODAM2 may be positioned closer to the non-display area NDA or the protruding area PA than the end of the bottom light-transmitting film OPVX.

[0184] Light-transmitting film dams ODAM1 and ODAM2 can be disposed on the intermediate layer OLD. ODAM1 and ODAM2 prevent the light-transmitting film LT from overflowing into or outside the non-display area NDA. In some embodiments, light-transmitting film dams ODAM1 and ODAM2 may include a first light-transmitting film dam ODAM1 and a second light-transmitting film dam ODAM2. Although the display panel 100 includes two light-transmitting film dams ODAM1 and ODAM2 in the accompanying drawings, this disclosure is not limited thereto. The display panel 100 may include one, three, or more light-transmitting film dams.

[0185] The light-transmitting membrane dams ODAM1 and ODAM2 and the bottom light-transmitting membrane OPVX can comprise the same material and can be disposed in the same layer. In embodiments, for example, the light-transmitting membrane dams ODAM1 and ODAM2 can comprise propylene glycol methyl ether acetate, methacrylate-benzyl methacrylate copolymer, polyfunctional acrylate, and a photoinitiator. The light-transmitting membrane dams ODAM1 and ODAM2 can be formed together with the bottom light-transmitting membrane OPVX via the same process. In embodiments, for example, the light-transmitting membrane dams ODAM1 and ODAM2 can be formed together with the bottom light-transmitting membrane OPVX via a deposition process or a photolithography process.

[0186] In some embodiments, one end of the bottom transparent membrane OPVX, the first transparent membrane dam ODAM1, and the second transparent membrane dam ODAM2 may be spaced apart from each other.

[0187] According to this embodiment, the display device 10 may include stop members STP1, STP2, and STP3. Stop members STP1, STP2, and STP3 may be disposed below the light-transmitting film LT. In this embodiment, for example, stop members STP1, STP2, and STP3 may be disposed below the first light-transmitting layer LT_L1, the second light-transmitting layer LT_L2, and the third light-transmitting layer LT_L3, respectively.

[0188] The stop elements STP1, STP2, and STP3 may be features that prevent the light-transmitting film LT from overflowing. In an embodiment, for example, the end of the light-transmitting film LT may not extend beyond the ends of the stop elements STP1, STP2, and STP3. Specifically, the end of the light-transmitting film LT may coincide with the ends of the stop elements STP1, STP2, and STP3, or it may be further inward than the ends of the stop elements STP1, STP2, and STP3.

[0189] Due to the change in membrane quality caused by the breakage of the stop members STP1, STP2 and STP3 at their ends, and the surface tension of the light-transmitting membrane LT itself, the ends of the light-transmitting membrane LT disposed on the stop members STP1, STP2 and STP3 may not extend beyond the ends of the stop members STP1, STP2 and STP3.

[0190] The stop components STP1, STP2 and STP3 may include a first stop component STP1, a second stop component STP2 and a third stop component STP3.

[0191] The first stop element STP1 may be part of the bottom light-transmitting film OPVX. The first stop element STP1 may be the end of the bottom light-transmitting film OPVX adjacent to the light-transmitting film dams ODAM1 and ODAM2. The end of the first light-transmitting layer LT_L1 may be disposed on the first stop element STP1, and the first stop element STP1 may prevent the first light-transmitting layer LT_L1 from overflowing.

[0192] The end of the first light-transmitting layer LT_L1 may not extend beyond the end of the first stop member STP1. The end of the first light-transmitting layer LT_L1 may coincide with the end of the first stop member STP1, or it may be further inward than the end of the first stop member STP1.

[0193] The second stop element STP2 and the first light-shielding layer LS_L1 may contain the same material and may be disposed in the same layer. The second stop element STP2 may be formed using the same process as the first light-shielding layer LS_L1. The second stop element STP2 may be spaced apart from multiple light-shielding patterns of the first light-shielding layer LS_L1. The end of the second light-transmitting layer LT_L2 may be disposed on the second stop element STP2, and the second stop element STP2 may prevent the second light-transmitting layer LT_L2 from overflowing.

[0194] The end of the second light-transmitting layer LT_L2 may not extend beyond the end of the second stop member STP2. The end of the second light-transmitting layer LT_L2 may coincide with the end of the second stop member STP2, or may be further inward than the end of the second stop member STP2. The end of the second light-transmitting layer LT_L2 may protrude further outward than the end of the first light-transmitting layer LT_L1.

[0195] In some embodiments, the second stop member STP2 may be disposed on the intermediate layer OLD and the first light-transmitting membrane dam ODAM1. The second stop member STP2 may overlap with the first light-transmitting membrane dam ODAM1 on the third-direction DR3. The second stop member STP2 may cover at least a portion of the upper surface and at least a portion of the side surface of the first light-transmitting membrane dam ODAM1.

[0196] The third stop element STP3 and the second light-shielding layer LS_L2 may contain the same material and may be disposed in the same layer. The third stop element STP3 may be formed using the same process as the second light-shielding layer LS_L2. The third stop element STP3 may be spaced apart from multiple light-shielding patterns of the second light-shielding layer LS_L2. The end of the third light-transmitting layer LT_L3 may be disposed on the third stop element STP3, and the third stop element STP3 may prevent the third light-transmitting layer LT_L3 from overflowing.

[0197] The end of the third light-transmitting layer LT_L3 may not extend beyond the end of the third stop member STP3. The end of the third light-transmitting layer LT_L3 may coincide with the end of the third stop member STP3, or may be further inward than the end of the third stop member STP3. The end of the third light-transmitting layer LT_L3 may protrude further outward than the end of the second light-transmitting layer LT_L2.

[0198] In some embodiments, a third stop member STP3 may be disposed on the intermediate layer OLD and the second light-transmitting membrane dam ODAM2. The third stop member STP3 may overlap with the second light-transmitting membrane dam ODAM2 on a third-direction DR3. The third stop member STP3 may cover at least a portion of the upper surface and at least a portion of the side surface of the second light-transmitting membrane dam ODAM2.

[0199] Since the display device 10 according to this embodiment includes a first stop member STP1, a second stop member STP2, and a third stop member STP3 respectively disposed under the first light-transmitting layer LT_L1, the second light-transmitting layer LT_L2, and the third light-transmitting layer LT_L3, overflow of the first light-transmitting layer LT_L1, the second light-transmitting layer LT_L2, and the third light-transmitting layer LT_L3 can be prevented when the first light-transmitting layer LT_L1, the second light-transmitting layer LT_L2, and the third light-transmitting layer LT_L3 are formed by inkjet printing process.

[0200] As the number of light-shielding layers included in the light-shielding film LS increases and the overall thickness of the light control layer LCL increases, the viewing angle can be controlled more effectively. Correspondingly, the number of light-transmitting layers included in the light-transmitting film LT can also be increased.

[0201] The display device 10 according to this embodiment includes stop members STP1, STP2 and STP3 for preventing overflow of each light-transmitting layer included in the light-transmitting film LT, wherein the first stop member STP1 is formed as part of the bottom light-transmitting film OPVX, the second stop member STP2 is formed in the same process as the first light-shielding layer LS_L1, and the third stop member STP3 is formed in the same process as the second light-shielding layer LS_L2, thereby simplifying the process.

[0238] The display device 10 according to this embodiment includes stop members STP1, STP2 and STP3 for preventing overflow of each light-transmitting layer included in the light-transmitting film LT, wherein the first stop member STP1, the second stop member STP2 and the third stop member STP3 are respectively formed as part of the first bottom light-transmitting film OPVX1, the second bottom light-transmitting film OPVX2 and the third bottom light-transmitting film OPVX3, thereby simplifying the process.

[0239] Figure 11 This is a cross-sectional view showing another embodiment of the display area, non-display area, and protruding area of ​​the display panel.

[0240] Figure 11 The display device 10 in the embodiment and Figure 8 The difference in the display device 10 in the embodiments of the above is that the second stop member STP2 and the third stop member STP3 have different positions and shapes.

[0241] More specifically, as referenced above Figure 8 Like the display device 10 in the embodiments described, the second stop member STP2 and the third stop member STP3 may each include the same material as the first light-shielding layer LS_L1 and the second light-shielding layer LS_L2, may each be disposed in the same layer, and may each be formed by the same process.

[0242] The display device 10 according to this embodiment and Figure 8 The difference in the display device 10 in the embodiments of the above is that the second stop member STP2 and the third stop member STP3 can be disposed further inward than the light-transmitting film dams ODAM1 and ODAM2.

[0243] The second stop member STP2 and the third stop member STP3 may not overlap with the light-transmitting membrane dams ODAM1 and ODAM2 on the third-direction DR3. In some embodiments, the outer boundary of the end of each of the second stop member STP2 and the third stop member STP3 may coincide with the outer boundary of the end of the first stop member STP1. However, it should be understood that the embodiments of this disclosure are not limited thereto. The outer boundary of the end of each of the second stop member STP2 and the third stop member STP3 may be further inward than the outer boundary of the end of the first stop member STP1.

[0244] In the display device 10 according to this embodiment, the second stop member STP2 and the third stop member STP3 can be disposed further inward than the light-transmitting film dams ODAM1 and ODAM2, thereby reducing the size of the non-display area NDA or the protruding area PA. Accordingly, the size of the unused space can be reduced.

[0245] Figure 12This is a cross-sectional view illustrating another embodiment of the display area of ​​a display panel according to the present disclosure.

[0246] Figure 12 The display device 10 in the embodiment is the same as the one mentioned above. Figure 7 or Figure 9 The difference between the display device 10 in the embodiments described above and the one described above is that the former includes a first intermediate layer OLD1, a second intermediate layer OLD2 and a third intermediate layer OLD3.

[0247] More specifically, as referenced above Figure 9 Similar to the described display device 10, the display device 10 according to this embodiment may include a first bottom light-transmitting film OPVX1, a second bottom light-transmitting film OPVX2, and a third bottom light-transmitting film OPVX3.

[0248] It should be noted that, compared with the reference Figure 9 The display device 10 described is different. According to this embodiment, the display device 10 may include a first intermediate layer OLD1, a second intermediate layer OLD2 and a third intermediate layer OLD3.

[0249] The first intermediate layer OLD1 and the above reference Figure 7 and Figure 9 The intermediate layers OLD are described as substantially the same; therefore, redundant descriptions will be omitted. The second intermediate layer OLD2 and the third intermediate layer OLD3 may contain the same material as the first intermediate layer OLD1.

[0250] The second intermediate layer OLD2 can be disposed on the first light-transmitting layer LT_L1 and the first light-shielding layer LS_L1. The second intermediate layer OLD2 can be disposed between the first light-transmitting layer LT_L1 and the second bottom light-transmitting film OPVX2, and between the first light-shielding layer LS_L1 and the second bottom light-transmitting film OPVX2.

[0251] The third intermediate layer OLD3 can be disposed on the second light-transmitting layer LT_L2 and the second light-shielding layer LS_L2. The third intermediate layer OLD3 can be disposed between the second light-transmitting layer LT_L2 and the third bottom light-transmitting film OPVX3, and between the second light-shielding layer LS_L2 and the third bottom light-transmitting film OPVX3.

[0252] In the display device 10 according to this embodiment, a first intermediate layer OLD1 is disposed between a planarization film PAS and a first bottom transparent film OPVX1, a second intermediate layer OLD2 is disposed between a first transparent layer (also referred to as a first transparent layer) LT_L1 and a second bottom transparent film OPVX2, and a third intermediate layer OLD3 is disposed between the second transparent layer LT_L2 and the third bottom transparent film OPVX3. Accordingly, the interface characteristics can be increased so that during the deposition process of the first to third bottom transparent films OPVX1, OPVX2 and OPVX3, the first to third bottom transparent films OPVX1, OPVX2 and OPVX3 can be easily deposited on organic films such as the planarization film PAS, the first transparent layer LT_L1 and the second transparent layer LT_L2.

[0253] In concluding this detailed description, those skilled in the art will understand that many variations and modifications can be made to the preferred embodiments without substantially departing from the principles of this disclosure. Therefore, the preferred embodiments disclosed herein are used only in a general and descriptive sense and not for limiting purposes.
