Description

[0001] Cross-reference to related applications

[0002] This application claims priority to Korean Patent Application No. 10-2024-0177422, filed in Korea on December 3, 2024, the entire contents of which are incorporated herein by reference as if fully set forth herein. Technical Field

[0003] This disclosure relates to electronic devices, and more specifically, to display devices. Background Technology

[0004] With advancements in display technology, display devices can offer additional functions beyond image display, such as image capture and sensing capabilities. To provide these functions, display devices may include optical and electronic components, such as lenses and sensors for detecting images.

[0005] In order to receive light passing through the front surface of the display device, it is desirable to place such optical electronics in an area of ​​the display device where the incident light passing through the front surface can be increasingly received and detected. Therefore, in such a display, the optical electronics can be located at the front of the display device, allowing the optical electronics to be effectively exposed to incident light. To mount the optical electronics in the display device in this configuration, the bezel area of ​​the display device can be increased, or recesses or holes can be formed in the display area of ​​the relevant display panel.

[0006] According to this configuration, when the display device includes optical electronics (such as lenses, sensors, etc.) for receiving or detecting light incident through the front surface and performing the intended function, the size of the front bezel of the display device may increase, or it may significantly limit the design of the front of the display device. Furthermore, in configurations where the display device includes optical electronics, the image quality produced by the display device may be degraded due to the structure in which the optical electronics are arranged within the display device.

[0007] Therefore, there is a need for display devices with an improved light-transmitting structure that allows optical electronics positioned below or at the bottom of the display panel to effectively receive light without being visible in front of the display. Summary of the Invention

[0034] In the following description of examples or embodiments of this disclosure, reference will be made to the accompanying drawings, which illustrate specific examples or embodiments that may be implemented. The same reference numerals and symbols may be used to denote the same or similar components, even when these components are shown in different drawings. The advantages and features of this disclosure and its implementation methods will be elucidated by the following exemplary embodiments described with reference to the accompanying drawings. However, this disclosure may be embodied in different forms and should not be construed as limited to the exemplary embodiments set forth herein. Rather, these exemplary embodiments are provided so that this disclosure may be sufficiently comprehensive and complete to assist those skilled in the art in fully understanding the scope of this disclosure. Furthermore, the scope of protection of this disclosure is defined by the claims and their equivalents. In the following description, detailed descriptions of relevant known functions or configurations may be omitted where such detailed descriptions might unnecessarily obscure aspects of this disclosure. The shapes, dimensions, ratios, angles, quantities, etc., shown in the drawings for describing various exemplary embodiments of this disclosure are given by way of example only. Therefore, this disclosure is not limited to the illustrations in the drawings. Terms used herein, such as “including,” “having,” “comprising,” “forming,” “of,” and “formed by,” are generally intended to allow for the addition of additional components unless used with the term “only.” As used herein, the singular form is intended to include the plural form unless the context clearly indicates otherwise.

[0035] Terms such as “first,” “second,” “A,” “B,” “(A),” or “(B)” may be used herein to describe elements of this disclosure. These terms are used only to distinguish one element from another. For example, without departing from the scope of this disclosure, a first element may be referred to as a second element, and similarly, a second element may be referred to as a first element.

[0036] When referring to the first element as "connected or linked to," "in contact with," or "overlapping" with the second element, it should be interpreted as meaning that not only can the first element be "directly connected or linked to," "directly in contact with," or "directly overlapping" with the second element, but also that a third element can be "inserted" between the first and second elements, or that the first and second elements can be "connected or linked," "in contact with," or "overlapping" with each other via a fourth element. Here, the second element can be included in at least one of two or more elements that are "connected or linked," "in contact with," or "overlapping" with each other.

[0037] When describing positional relationships, such as using terms like "above," "over," "below," "above," "below," "beside," or "immediately following" to describe the positional relationship between two components, one or more other components may be positioned between the two components unless more restrictive terms such as "immediately," "directly," or "nearly" are used. For example, when placing one element or layer "above" another element or layer, a third element or layer may be inserted in between. Furthermore, the terms "left," "right," "top," "bottom," "down," "up," "above," and "below" refer to any frame of reference.

[0038] Furthermore, when referring to any size, relative size, etc., it should be understood that even without a specific description, the numerical values ​​or corresponding information (e.g., levels, ranges, etc.) of an element or feature include tolerances or error ranges that may be caused by a variety of factors (e.g., process factors, internal or external influences, noise, etc.). Moreover, the term "may" fully encompasses all the meanings of the term "capable". Features of the various embodiments of this disclosure may be combined or integrated with each other in part or in whole, and may be linked and operated in a variety of technically diverse ways, and the embodiments may be implemented independently or in relation to each other.

[0039] In the following description, several exemplary aspects of this disclosure are described in detail with reference to the accompanying drawings. Regarding the reference numerals for elements in the various drawings, the same elements may be shown in other drawings, and similar reference numerals may refer to similar elements unless otherwise stated. The same or similar elements may be represented by the same reference numerals, even if they are depicted in different drawings. Furthermore, for ease of description, the scale, dimensions, size, and thickness of the elements shown in the drawings may differ from the actual scale, dimensions, size, and thickness; therefore, aspects of this disclosure are not limited to the scale, dimensions, size, and thickness shown in the drawings.

[0040] Figures 1A to 1D An exemplary display device according to aspects of this disclosure is shown.

[0041] Reference Figures 1A to 1D In one or more exemplary embodiments, the display device 100 may include a display panel 110 for displaying images and one or more optical electronics (11 and / or 12).

[0042] The display panel 110 may include a display area DA in which an image can be displayed and a non-display area NDA in which no image is displayed.

[0043] Multiple subpixels can be set in the display area DA, and several types of signal lines for driving the multiple subpixels can be set therein.

[0044] The non-display area NDA can be the area outside the display area DA. Several types of signal lines can be set in the non-display area NDA, and several types of drive circuits can be connected to it. At least a portion of the non-display area NDA can be bent so that it is not visible in front of the display device 100, or it can be covered by the housing or casing of the display device 100. The non-display area NDA can also be referred to as an active area, bezel, or border area.

[0045] Reference Figures 1A to 1D In one or more aspects, one or more optical electronic devices (11 and / or 12) included in the display device 100 may be located below or on the lower part of the display panel 110 (opposite to its viewing surface).

[0046] Light can enter the front surface (viewing surface) of the display panel 110, pass through the display panel 110, and reach one or more optical electronic devices (11 and / or 12) located below or on the lower part of the display panel 110 (opposite to the viewing surface).

[0047] One or more optical electronic devices (11 and / or 12) may be devices capable of receiving or detecting light passing through the display panel 110 and performing predetermined functions based on the received light. For example, one or more optical electronic devices (11 and / or 12) may include one or more of the following: image capturing devices such as lenses (image sensors); or sensors such as proximity sensors, illuminance sensors, etc.

[0048] Reference Figures 1A to 1D In one or more aspects, the display area DA of the display panel 110 may include one or more optical areas (OA1 and / or OA2) and a general area NA. In this document, the term "general area" NA refers to an area that exists within the display area DA but does not overlap with one or more optical electronic devices (11 and / or 12), and may also be referred to as a non-optical area. According to one embodiment, the "general area" NA of the display may be referred to as the standard pixel area of ​​the display, the general display area, or the non-optical area, etc.

[0049] One or more optical regions (OA1 and / or OA2) can be one or more regions that overlap with one or more optical electronic devices (11 and / or 12) respectively in a cross-sectional view of the display panel 110.

[0050] Reference Figure 1A In one or more aspects, the display area DA may include a first optical area OA1 and a conventional area NA. In this configuration, at least a portion of the first optical area OA1 may overlap with the first optoelectronic device 11 (e.g., a lens or sensor).

[0051] Figure 1A The diagram shows a structure in which the first optical region OA1 has a circular shape, but the shape of the first optical region OA1 according to aspects of this disclosure is not limited thereto.

[0052] For example, such as Figure 1B As shown, the first optical region OA1 can have an octagonal shape or a variety of polygonal shapes.

[0053] Reference Figure 1C In one or more exemplary embodiments, the display area DA may include a first optical area OA1, a second optical area OA2, and a conventional area NA. In this configuration, a portion of the conventional area NA may exist between the first optical area OA1 and the second optical area OA2. At least a portion of the first optical area OA1 may overlap with the first optoelectronic device 11, and at least a portion of the second optical area OA2 may overlap with the second optoelectronic device 12.

[0054] Reference Figure 1D In one or more aspects, the display area DA may include a first optical area OA1, a second optical area OA2, and a conventional area NA. In this configuration, the conventional area NA may not exist between the first optical area OA1 and the second optical area OA2. For example, the first optical area OA1 and the second optical area OA2 may be in contact with each other (e.g., in direct contact). In this example, at least a portion of the first optical area OA1 may overlap with the first optoelectronic device 11, and at least a portion of the second optical area OA2 may overlap with the second optoelectronic device 12.

[0055] In one or more aspects, it is desirable that one or more optical regions (OA1 and / or OA2) included in the display panel 110 or display device 100 include both image display structures and light-transmitting structures. For example, since one or more optical regions (OA1 and / or OA2) are part of the display area DA, it is desirable that sub-pixels for displaying images be provided in one or more optical regions (OA1 and / or OA2). Furthermore, in order for one or more optoelectronic devices (11 and / or 12) to fully receive light, it is desirable that one or more optical regions (OA1 and / or OA2) include light-transmitting structures.

[0056] In the following text, the image display structure may be referred to as the light-emitting area, and the light-transmitting structure may be referred to as the transmission area.

[0057] It should be noted that even if one or more optical electronics (11 and / or 12) are required to receive light, one or more optical electronics (11 and / or 12) may be located below or on the lower part of the display panel 110 (e.g., on the opposite side of its viewing surface). Therefore, in this configuration, one or more optical electronics (11 and / or 12) may be configured to receive light passing through the display panel 110.

[0058] One or more optical electronic devices (11 and / or 12) may not be exposed on the front surface (viewing surface) of the display panel 110, and therefore, when the user views the front surface of the display device 100, one or more optical electronic devices (11 and / or 12) may be invisible or imperceptible to the user.

[0059] The first optical electronic device 11 may be, for example, a lens, and the second optical electronic device 12 may be, for example, a sensor. The sensor may be a proximity sensor, an illumination sensor, an infrared sensor, etc. In one or more aspects, the lens may be a lens element, an image sensor, or a unit including at least one of a lens element and an image sensor, and the sensor may be an infrared sensor capable of detecting infrared light.

[0060] In one or more aspects, the first optical electronic device 11 may be a sensor, and the second optical electronic device 12 may be a lens.

[0061] In the following discussion, for ease of description, examples of the first optical electronic device 11 being a lens and the second optical electronic device 12 being a sensor are provided. However, it should be understood that the scope of this disclosure includes examples of the first optical electronic device 11 being a sensor and the second optical electronic device 12 being a lens. The lens can be, for example, a lens element, an image sensor, or a unit including at least one of a lens element and an image sensor.

[0062] In an example where the first optical electronic device 11 is a lens, the lens can be located below or at the bottom of the display panel 110, and can be a front-facing lens capable of capturing objects or images in the forward direction of the display panel 110. Therefore, the user can capture images or objects through a lens that is not visible on the viewing surface while viewing the display panel 110.

[0063] It should be noted here that, Figures 1A to 1DIn each of the display areas DA, the conventional area NA and one or more optical areas (OA1 and / or OA2) are areas capable of displaying images, and the conventional area NA is an area that does not require a light-transmitting structure, but the one or more optical areas (OA1 and / or OA2) are areas that require a light-transmitting structure. Therefore, in one or more aspects, the conventional area NA can be an area without a light-transmitting structure or without a light-transmitting structure, and the one or more optical areas (OA1 and / or OA2) can be areas in which a light-transmitting structure is implemented or included.

[0064] Therefore, one or more optical regions (OA1 and / or OA2) may have a transmittance greater than or equal to a predetermined level, such as relatively high transmittance, while the conventional region NA may have a transmittance less than the predetermined level or no transmittance (e.g., opaque).

[0065] For example, one or more optical regions (OA1 and / or OA2) may have different resolutions, subpixel arrangement structures, number of subpixels per unit area, electrode structures, line structures, electrode arrangement structures, line arrangement structures, etc., than those of a conventional region NA.

[0066] In one or more aspects, the number of subpixels per unit area in one or more optical regions (OA1 and / or OA2) may be less than the number of subpixels per unit area in a conventional region NA. For example, the resolution of one or more optical regions (OA1 and / or OA2) may be lower than the resolution of the conventional region NA. Here, the number of subpixels per unit area can be a unit used to measure resolution, for example, referred to as pixels per inch (or subpixels) (PPI), which represents the number of pixels (or subpixels) per inch. Furthermore, according to one embodiment, the subpixels in one or more optical regions may have a different size or shape than the subpixels in the conventional region. For example, the subpixels in one or more optical regions may be larger than the subpixels in the conventional region, but spaced further apart, etc., but the embodiment is not limited to this.

[0067] In one or more aspects, in Figures 1A to 1D In each of these, the number of sub-pixels per unit area in the first optical region OA1 can be less than the number of sub-pixels per unit area in the conventional region NA. In one or more aspects, in Figure 1C and Figure 1D In each of them, the number of sub-pixels per unit area in the second optical region OA2 can be greater than or equal to the number of sub-pixels per unit area in the first optical region OA1.

[0068] exist Figures 1A to 1DIn each of these, the first optical region OA1 can have various shapes, such as circular, elliptical, quadrilateral, hexagonal, octagonal, etc. Figure 1C and Figure 1D In each of them, the second optical region OA2 can have a variety of shapes, such as circular, elliptical, quadrilateral, hexagonal, octagonal, etc. The first optical region OA1 and the second optical region OA2 can have the same, substantially the same, or nearly the same shape, or different shapes.

[0069] Reference Figure 1D In instances where the first optical region OA1 and the second optical region OA2 are in contact with each other (e.g., in direct contact), the entire optical region including the first optical region OA1 and the second optical region OA2 can also have various shapes, such as circles, ellipses, quadrilaterals, hexagons, octagons, etc.

[0070] In the following description, for convenience in relation to the shape of the optical regions (OA1 and OA2), each of the first optical region OA1 and the second optical region OA2 is considered to have a circular shape. However, it should be understood that the scope of this disclosure includes instances in which at least one of the first optical region OA1 and the second optical region OA2 has a shape other than a circular shape.

[0071] A display device 100 having a structure in which a first optical electronic device 11, such as a lens, is located below or at the bottom of the display panel 100 and is not exposed to the outside can be referred to as a display in which under-display lens (UDC) technology is implemented.

[0072] According to this structure, the display device 100 can provide the advantage of preventing a reduction in the size of the display area DA, because it is not necessary to form a recess or lens hole in the display panel 110 to expose the lens. For example, the use of a hole or recess for the lens can be avoided, and a completely recess-free image screen can be provided to the user.

[0073] In fact, since there is no need to form a recess or lens hole in the display panel 110 for lens exposure, the display device 100 can provide the further advantage of reducing the size of the bezel area and increasing design freedom, because such design constraints are eliminated.

[0074] Although one or more optical electronics (11 and / or 12) are located below or under the display panel 110 of the display device 100 (e.g., hidden or not exposed to the outside), one or more optical electronics (11 and / or 12) are used to perform normal predetermined functions and thus receive or detect light.

[0075] Furthermore, although one or more optoelectronic devices (11 and / or 12) of the display device 100 are located below or at the bottom of the display panel 110 to be hidden and positioned to overlap with the display area DA, it is desirable to perform normal image display in one or more optical areas (OA1 and / or OA2) of the display area DA that overlap with one or more optoelectronic devices (11 and / or 12). Therefore, in one or more aspects, even if one or more optoelectronic devices (11 and / or 12) are located on the back of the display panel, images can be displayed in a normal manner (e.g., without degrading image quality) in one or more optical areas (OA1 and / or OA2) of the display area DA that overlap with one or more optoelectronic devices (11 and / or 12).

[0076] Figure 2 An exemplary system configuration of a display device 100 according to aspects of this disclosure is shown.

[0077] Reference Figure 2 The display device 100 may include a display panel 110 and at least one display driving circuit as components for displaying one or more images.

[0078] At least one display driving circuit may be a circuit for driving the display panel 110, and includes a data driving circuit 220, a gate driving circuit 230, a controller 240 and other circuit components.

[0079] The display panel 110 may include a display area DA in which an image may be displayed and a non-display area NDA in which no image is displayed. The non-display area NDA may be an area outside the display area DA and may also be referred to as a non-active area or a bezel area. All or at least a portion of the non-display area NDA may be an area visible from the front surface of the display device 100, or a bent area that is not visible from the front surface of the device 100.

[0080] The display panel 110 may include a substrate SUB and a plurality of sub-pixels SP disposed on the substrate SUB. The display panel 110 may also include several types of signal lines to drive the plurality of sub-pixels SP.

[0081] In one or more aspects, the display device 100 herein may be a liquid crystal display device or the like, or a self-emissive display device in which light is emitted from the display panel 110 itself. In an example where the display device 100 is a self-emissive display device, each of the plurality of sub-pixels SP included in the display panel 110 may include a light-emitting element.

[0082] For example, the display device 100 according to aspects of this disclosure can be an organic light-emitting display device in which organic light-emitting diodes (OLEDs) are used to realize the light-emitting elements. In another example, the display device 100 according to aspects of this disclosure can be an inorganic light-emitting display device in which light-emitting diodes based on inorganic materials are used to realize the light-emitting elements. In yet another embodiment, the display device 100 according to aspects of this disclosure can be a quantum dot display device in which quantum dots, which are self-emissive semiconductor crystals, are used to realize the light-emitting elements.

[0083] The structure of each of the plurality of subpixels SP can be configured or designed differently depending on the type of display device 100. For example, when the display device 100 is a self-emissive display device that includes self-emissive subpixels SP, each subpixel SP may include a self-emissive light-emitting element, one or more transistors and one or more capacitors.

[0084] In one or more aspects, the signal lines arranged in the display device 100 may include, for example, a plurality of data lines DL for carrying data signals (which may be referred to as data voltages or image signals), a plurality of gate lines GL for carrying gate signals (which may be referred to as scan signals), etc.

[0085] A plurality of data lines DL and a plurality of gate lines GL may intersect each other. Each of the plurality of data lines DL may extend in a first direction. Each of the plurality of gate lines GL may extend in a second direction other than the first direction.

[0086] For example, the first direction can be a column direction or a vertical direction, and the second direction can be a row direction or a horizontal direction. In another example, the first direction can be a row direction or a horizontal direction, and the second direction can be a column direction or a vertical direction.

[0087] The data driving circuit 220 can be a circuit for driving a plurality of data lines DL, and can supply data signals to the plurality of data lines DL. The gate driving circuit 230 can be a circuit for driving a plurality of gate lines GL, and can supply gate signals to the plurality of gate lines GL.

[0088] The controller 240 can be a device for controlling the data drive circuit 220 and the gate drive circuit 230, and can control the driving timing of a plurality of data lines DL and the driving timing of a plurality of gate lines GL.

[0089] The controller 240 can supply a data control signal DCS to the data drive circuit 220 to control the data drive circuit 220, and supply a gate control signal GCS to the gate drive circuit 230 to control the gate drive circuit 230.

[0090] The controller 240 can receive image data input from the host system 250 and supply image data DATA that can be read by the data driving circuit 220 based on the input image data.

[0091] The data drive circuit 220 can supply data signals to multiple data lines DL according to the drive timing control of the controller 240.

[0092] The data drive circuit 220 can receive digital image data DATA from the controller 240, convert the received image data DATA into an analog data signal, and output the resulting analog data signal to multiple data lines DL.

[0093] The gate drive circuit 230 can supply gate signals to a plurality of gate lines GL according to the timing control of the controller 240. The gate drive circuit 230 can receive a first gate voltage corresponding to the on-level voltage and a second gate voltage corresponding to the off-level voltage, as well as various gate drive control signals GCS, generate gate signals, and supply the generated gate signals to the plurality of gate lines GL.

[0094] In one or more aspects, the data drive circuit 220 may be connected to the display panel 110 via tape automatic bonding (TAB) technology, or to conductive pads, such as bonding pads, of the display panel 110 via chip-on-glass (COG) technology or chip-on-panel (COP) technology, or to the display panel 110 via chip-on-film (COF) technology.

[0095] In one or more aspects, the gate driving circuit 230 can be connected to the display panel 110 via tape-on-board (TAB) technology, or to conductive pads, such as bonding pads, of the display panel 110 via chip-on-glass (COG) or chip-on-film (COP) technology, or to the display panel 110 via chip-on-film (COF) technology. In one or more aspects, the gate driving circuit 230 can be disposed in the non-display area NDA of the display panel 110 via gate-in-panel (GIP) technology. The gate driving circuit 230 can be disposed on the substrate or connected to the substrate. In an example where the gate driving circuit 230 is implemented using GIP technology, the gate driving circuit 230 can be disposed in the non-display area NDA of the substrate SUB. In an example where the gate driving circuit 230 is implemented using chip-on-glass (COG), chip-on-film (COF), or other technologies, the gate driving circuit 230 can be connected to the substrate SUB.

[0096] In one or more aspects, at least one of the data driving circuit 220 and the gate driving circuit 230 may be disposed in the display area DA of the display panel 110. For example, at least one of the data driving circuit 220 and the gate driving circuit 230 may be configured not to overlap with the sub-pixel SP, or configured to overlap with one or more or all of the sub-pixels SP, or to overlap with at least one or more corresponding portions of one or more sub-pixels.

[0097] In one or more aspects, the data driving circuit 220 may be disposed in and / or electrically connected to only one side or edge (e.g., upper or lower) of the display panel 110, but is not limited thereto. In one or more aspects, depending on the driving scheme, panel design, etc., the data driving circuit 220 may be located in at least two of the two sides or edges (e.g., upper and lower) or four sides or edges (e.g., upper, lower, left, and right) of the display panel 110, and / or electrically connected to at least two of the two sides or edges (e.g., upper and lower) or four sides or edges (e.g., upper, lower, left, and right) of the display panel 110, but is not limited thereto.

[0098] In one or more aspects, the gate driving circuit 230 may be located in and / or electrically connected to one side or edge (e.g., left or right) of the display panel 110, but is not limited thereto. In one or more aspects, depending on the driving scheme, panel design, etc., the gate driving circuit 230 may be located in at least two of the two sides or edges (e.g., left and right) or four sides or edges (e.g., upper, lower, left, and right) of the display panel 110, and / or electrically connected to at least two of the two sides or edges (e.g., left and right) or four sides or edges (e.g., upper, lower, left, and right) of the display panel 110, but is not limited thereto.

[0099] The controller 240 can be implemented in a separate component with the data drive circuit 220, or integrated with the data drive circuit 220, so that the controller 240 and the data drive circuit 220 can be implemented in a single integrated circuit.

[0100] Controller 240 may be a timing controller used in display technology, or a control device capable of performing additional control functions besides those of a timing controller. In one or more aspects, controller 240 may be one or more other control circuits, or circuits or components in a control device, different from a timing controller. Controller 240 may be implemented using various circuits or electronic components such as integrated circuits (ICs), field-programmable gate arrays (FPGAs), application-specific integrated circuits (ASICs), processors, etc.

[0101] The controller 240 can be mounted on a printed circuit board, flexible printed circuit, etc., and can be electrically connected to the data drive circuit 220 and the gate drive circuit 230 through the printed circuit board, flexible printed circuit, etc.

[0102] The controller 240 can transmit signals to and receive signals from the data drive circuit 220 via one or more predetermined interfaces. For example, such interfaces may include a low-voltage differential signaling (LVDS) interface, an embedded point-to-point clock interface (EPI), a serial peripheral interface (SPI), etc.

[0103] In one or more aspects, to further provide touch sensing and image display functions, the display device 100 may include at least one touch sensor and a touch sensing circuit, the touch sensing circuit being able to detect whether a touch object (e.g., a finger, pen, etc.) has triggered a touch event or detect the corresponding touch position by sensing the touch sensor.

[0104] The touch sensing circuit may include a touch driver circuit 260 capable of generating and providing touch sensing data by driving and sensing a touch sensor, a touch controller 270 capable of using the touch sensing data to detect the occurrence of a touch event or to detect the touch position (or touch coordinates), and one or more other components.

[0105] The touch sensor may include a plurality of touch electrodes. The touch sensor may also include a plurality of touch lines for electrically connecting the plurality of touch electrodes to the touch driving circuit 260.

[0106] The touch sensor can be implemented as a touch panel external to the display panel 110 or integrated inside the display panel 110. A touch sensor external to the display panel 110 can be referred to as an add-on touch sensor. In an example where an add-on touch sensor is disposed in the display device 100, the touch panel and the display panel 110 can be manufactured separately and then combined during assembly. The add-on touch panel may include a touch panel substrate and a plurality of touch electrodes disposed on the touch panel substrate.

[0107] In an example where the touch sensor is integrated inside the display panel 110, the touch sensor can be formed on the substrate SUB together with the signal lines and electrodes associated with the display drive during the manufacturing process of the display panel 110.

[0108] The touch driving circuit 260 can supply a touch driving signal to at least one of a plurality of touch electrodes and sense at least one of the plurality of touch electrodes to generate touch sensing data.

[0109] Touch sensing circuits can perform touch sensing using self-capacitance sensing technology or mutual capacitance sensing technology.

[0110] In an example where a touch sensing circuit performs touch sensing using self-capacitance sensing technology, the touch sensing circuit can perform touch sensing based on the capacitance between one or more touch electrodes and an object such as a finger or pen.

[0111] According to self-capacitance sensing technology, each of the plurality of touch electrodes can be used as both a driving touch electrode and a sensing touch electrode. The touch driving circuit 260 can drive all or one or more of the plurality of touch electrodes, and sense all or one or more of the plurality of touch electrodes.

[0112] In an example where a touch sensing circuit performs touch sensing using mutual capacitance sensing technology, the touch sensing circuit can perform touch sensing based on the capacitance between the touch electrodes.

[0113] Based on mutual capacitance sensing technology, a plurality of touch electrodes can be divided into driving touch electrodes and sensing touch electrodes. The touch driving circuit 260 can drive the driving touch electrodes and sense the sensing touch electrodes.

[0114] In one or more aspects, the touch driving circuit 260 and the touch controller 270 included in the touch sensing circuit can be implemented in separate devices or in a single device. In one or more aspects, the touch driving circuit 260 and the data driving circuit 220 can be implemented in separate devices or in a single device.

[0115] The display device 100 may also include a power supply circuit for supplying several types of power to the display driving circuit and / or touch sensing circuit.

[0116] In one or more aspects, the display device 100 can be a mobile terminal, such as a smartphone, tablet, etc., or a monitor, television (TV), etc. Furthermore, the display device 100 can be configured with a wide variety of types, sizes, and shapes to display information or images. For example, the display device 100 can be applied to mobile devices, video phones, smartwatches, watch phones, wearable devices, foldable devices, rollable devices, bendable devices, flexible devices, stretchable devices, curved devices, sliding devices, variable devices, electronic notebooks, e-books, portable multimedia players (PMPs), personal digital assistants (PDAs), MP3 players, mobile medical devices, desktop PCs, laptop PCs, notebook computers, workstations, navigation devices, car navigation devices, vehicle display devices, vehicle equipment, theater equipment, theater display devices, televisions, wallpaper devices, signage devices, gaming devices, laptops, monitors, cameras, camcorders, and home appliances, etc.

[0117] As described above, the display area DA of the display panel 110 may include, for example: Figures 1A to 1D The diagram shows the conventional area NA and one or more optical areas (OA1 and / or OA2).

[0118] A regular area NA and one or more optical areas (OA1 and / or OA2) can be the areas in which images can be displayed. It should be noted that the regular area NA can be the area in which a light-transmitting structure is not required, and one or more optical areas (OA1 and / or OA2) can be the area in which a light-transmitting structure will be implemented.

[0119] Figure 3 An exemplary configuration of a display panel 110 according to aspects of this disclosure is shown.

[0120] Reference Figure 3 In one or more exemplary embodiments, the display area DA of the display panel 110 includes a conventional area NA, and the sub-pixels SP disposed in the first optical area OA1 and the second optical area OA2 may each include a light-emitting element ED disposed on the substrate SUB and disposed in the light-emitting area, a driving transistor DRT for driving the light-emitting element ED, a scanning transistor SCT for transmitting the data voltage VDATA to the first node N1 of the driving transistor DRT, a storage capacitor Cst for maintaining the voltage at an approximately constant level during a frame or a frame period, etc.

[0121] The driving transistor DRT may include: a first node N1 on which a data voltage is applied, a second node N2 electrically connected to a light-emitting element ED, and a third node N3 on which a driving voltage ELVDD delivered through the driving voltage line DVL is applied.

[0122] The first node N1 of the driving transistor DRT can be the gate node of the driving transistor DRT, and can be electrically connected to the source node or drain node of the scanning transistor SCT.

[0123] The second node N2 of the driving transistor DRT can be the source node or the drain node of the driving transistor DRT, and can also be electrically connected to the pixel electrode PE of the light-emitting element ED.

[0124] The third node N3 of the driving transistor DRT can be either the drain node or the source node of the driving transistor DRT.

[0125] A storage capacitor Cst can be connected between the first node N1 and the second node N2 of the driving transistor DRT. The storage capacitor Cst can store the amount of charge corresponding to the voltage difference between the two terminals and maintain this voltage difference for a predetermined frame time. According to this configuration, the corresponding sub-pixel SP can emit light continuously for the predetermined frame time.

[0126] The scanning transistor SCT can be controlled by a gate signal and can be connected between the first node N1 of the driving transistor DRT and the data line DL.

[0127] The scanning transistor SCT can be turned on by a gate signal with a turn-on level voltage delivered through the gate line GL, and the data voltage VDATA delivered through the data line DL is transmitted to the first node N1 of the driving transistor DRT.

[0128] The driving transistor DRT and the scanning transistor SCT can each be either an n-type transistor or a p-type transistor.

[0129] In an example where the scanning transistor SCT is an n-type transistor, the gate signal's on-state voltage can be a high-level voltage. In another example where the scanning transistor SCT is a p-type transistor, the gate signal's on-state voltage can be a low-level voltage.

[0130] The light-emitting element (ED) may include a pixel electrode (PE), a light-emitting layer (EL), and a common electrode (CE). A base voltage (ELVSS) may be applied to the common electrode (CE).

[0131] For example, the pixel electrode PE can be an anode electrode, and the common electrode CE can be a cathode electrode. In another example, the pixel electrode PE can be a cathode electrode, and the common electrode CE can be an anode electrode. In the following discussion, for ease of illustration, examples in which the pixel electrode PE is an anode electrode and the common electrode CE is a cathode electrode will be provided.

[0132] The light-emitting element (ED) can be, for example, an organic light-emitting diode (OLED), an inorganic light-emitting diode, a quantum dot light-emitting element, etc. In an example where an organic light-emitting diode is used as the light-emitting element (ED), its light-emitting layer (EL) may include an organic light-emitting layer containing organic materials.

[0133] The storage capacitor Cst can be an external capacitor designed to be located outside the driving transistor DRT, rather than an internal capacitor such as a parasitic capacitor (e.g., Cgs or Cgd) that can be formed between the gate node and the source node (or drain node) of the driving transistor DRT.

[0134] Since the circuit elements (e.g., particularly the light-emitting elements ED) in each sub-pixel SP are susceptible to external moisture or oxygen, an encapsulation layer ENCAP can be provided in the display panel PNL to prevent external moisture or oxygen from penetrating into the circuit elements (e.g., particularly the light-emitting elements ED). The encapsulation layer ENCAP can be provided on the light-emitting elements ED so that it covers the light-emitting elements ED.

[0135] It should be noted that Figure 3 The subpixel SP configuration shown is merely one example of possible subpixel configurations. For instance, the subpixel SP can be configured in a wide variety of ways depending on design requirements, and may also include one or more transistors and / or one or more capacitors.

[0136] Figure 4 The arrangement of aspects according to this disclosure is shown in a conventional area (e.g., Figures 1A to 1D The conventional region (NA) and the optical region (e.g., Figures 1A to 1D An exemplary arrangement of subpixels in the first optical region and / or the second optical region (OA1 and / or OA2).

[0137] Reference Figure 4 In one or more exemplary embodiments, a plurality of subpixels SP may be provided in each of the conventional region NA, the first optical region OA1, and the second optical region OA2 included in the display region DA.

[0138] The plurality of subpixels SP may include, for example, at least one red subpixel (red SP) that emits red light, at least one green subpixel (green SP) that emits green light, and at least one blue subpixel (blue SP) that emits blue light.

[0139] Therefore, the conventional region NA, the first optical region OA1, and the second optical region OA2 may each include the light-emitting region EA of the red sub-pixel (red SP), the light-emitting region EA of the green sub-pixel (green SP), and the light-emitting region EA of the blue sub-pixel (blue SP).

[0140] Reference Figure 4 The regular region NA may not include the transmissive region (e.g., the light-transmitting structure), but it does include the luminescent region EA.

[0141] In contrast, it is expected that the first optical region OA1 and the second optical region OA2 include both a plurality of emitting regions EA and a plurality of transmitting regions.

[0142] Therefore, in one or more aspects, the first optical region OA1 may include a plurality of light-emitting regions EA and a plurality of first transmission regions TA1, and the second optical region OA2 may include a plurality of light-emitting regions EA and a plurality of second transmission regions TA2.

[0143] The plurality of light-emitting areas EA and the plurality of transmissive areas (TA1 and / or TA2) can differ depending on whether light transmission is permitted. For example, the plurality of light-emitting areas EA can be areas where light transmission is not permitted (e.g., light transmission to the back of the display panel is not permitted), and the plurality of transmissive areas (TA1 and / or TA2) can be areas where light transmission is permitted (e.g., light transmission to the back of the display panel is permitted). For example, the transmissive areas (TA1 and / or TA2) can be the transparent areas of the screen.

[0144] Furthermore, the plurality of luminescent regions EA and the plurality of transmissive regions (TA1 and / or TA2) can also differ depending on whether a specific metal layer is included. For example, as Figure 3 The common electrode CE shown can be disposed in a plurality of light-emitting regions EA, but the common electrode CE cannot be disposed in a plurality of transmission regions (TA1 and / or TA2). For example, a light-shielding layer can be disposed in a plurality of light-emitting regions EA, but a light-shielding layer cannot be disposed in a plurality of transmission regions (TA1 and / or TA2).

[0145] Since the first optical region OA1 includes the first transmission region TA1 and the second optical region OA2 includes the second transmission region TA2, both the first optical region OA1 and the second optical region OA2 can be regions through which light can pass.

[0146] In one or more aspects, the transmittance of the first optical region OA1 and the transmittance of the second optical region OA2 may be substantially the same.

[0147] In this configuration, the first transmission region TA1 of the first optical region OA1 and the second transmission region TA2 of the second optical region OA2 can have substantially the same shape or size. In one or more aspects, even when the first transmission region TA1 of the first optical region OA1 and the second transmission region TA2 of the second optical region OA2 have different shapes or sizes, the ratio of the first transmission region TA1 to the first optical region OA1 and the ratio of the second transmission region TA2 to the second optical region OA2 can also be substantially the same. For example, the first transmission regions TA1 can each have the same shape and size, and the second transmission regions TA2 can each have the same shape and size.

[0148] In one or more aspects, the transmittance of the first optical region OA1 and the transmittance of the second optical region OA2 may be different from each other.

[0149] In this configuration, at least one of the plurality of first transmission regions TA1 of the first optical region OA1 and at least one of the plurality of second transmission regions TA2 of the second optical region OA2 may have different shapes or sizes from each other. In one or more aspects, even when the first transmission regions TA1 of the first optical region OA1 and the second transmission regions TA2 of the second optical region OA2 have substantially the same shape or size, the ratio of the first transmission region TA1 to the first optical region OA1 and the ratio of the second transmission region TA2 to the second optical region OA2 may be different from each other.

[0150] In one or more aspects, in an instance where the first optical electronic device 11 overlapping with the first optical region OA1 is a lens and the second optical electronic device 12 overlapping with the second optical region OA2 is a sensor for detecting an image, the lens may require a greater amount of light than the sensor.

[0151] Therefore, the transmittance of the first optical region OA1 can be greater than that of the second optical region OA2.

[0152] For example, the size of at least one of the first transmission regions TA1 of the first optical region OA1 may be larger than the size of at least one of the second transmission regions TA2 of the second optical region OA2. In one or more aspects, even when the first transmission region TA1 of the first optical region OA1 and the second transmission region TA2 of the second optical region OA2 have substantially the same size, the ratio of the first transmission region TA1 to the first optical region OA1 may be greater than the ratio of the second transmission region TA2 to the second optical region OA2.

[0153] like Figure 4The transmission regions shown (TA1, TA2) can be referred to as transparent regions, see-through regions, or open regions, and the term transmittance can be referred to as transparency.

[0154] Furthermore, in the following discussion, unless otherwise expressly stated, as Figure 4 As shown, it is assumed that the first optical region OA1 and the second optical region OA2 are located in the upper edge of the display area DA of the display panel 110, and are arranged adjacent to each other in the left and right directions, for example, in the direction in which the upper edge extends.

[0155] Reference Figure 4 The horizontal display area with a first optical region OA1 and a second optical region OA2 can be referred to as the first horizontal display area HA1, and another horizontal display area without the first optical region OA1 and the second optical region OA2 can be referred to as the second horizontal display area HA2.

[0156] Reference Figure 4 The first horizontal display area HA1 may include a portion of the conventional area NA, a first optical area OA1, and a second optical area OA2. The second horizontal display area HA2 may include only the conventional area NA.

[0157] Figure 5A and Figure 5B An exemplary arrangement of signal lines in a display panel 110 according to aspects of this disclosure is shown.

[0158] Figure 5A An exemplary arrangement of signal lines in each of the first optical region OA1 and the conventional region NA is shown. Figure 5B An exemplary arrangement of signal lines in each of the second optical region OA2 and the conventional region NA is shown.

[0159] Figure 5A and Figure 5B The first horizontal display area HA1 shown is a part of the first horizontal display area HA1 of the display panel 110. Figure 5A and Figure 5B The second horizontal display area HA2 shown is a part of the second horizontal display area HA2 of the display panel 110.

[0160] Figure 5A The first optical region OA1 shown is a part of the first optical region OA1 of the display panel 110, and Figure 5B The second optical region OA2 shown is a part of the second optical region OA2 of the display panel 110.

[0161] Reference Figure 5A and Figure 5B In one or more exemplary embodiments, the first horizontal display area HA1 may include a portion of the conventional area NA, a first optical area OA1, and a second optical area OA2. The second horizontal display area HA2 may include only the conventional area NA.

[0162] Several types of horizontal lines (HL1 and HL2) and several types of vertical lines (VLn, VL1 and VL2) can be set in the display panel 110.

[0163] In this document, the terms "horizontal" and "vertical" are used to refer to two intersecting directions in the display panel. However, it should be noted that the horizontal and vertical directions can be interchanged depending on the orientation in which the display panel 110 or display device 110 is viewed. The horizontal direction can refer, for example, the direction in which one of the gate lines GL extends, and the vertical direction can refer, for example, the direction in which one of the data lines DL extends. Therefore, the terms horizontal and vertical are used to represent two directions.

[0164] Reference Figure 5A and Figure 5B The horizontal lines set in the display panel 110 may include a first horizontal line HL1 set in the first horizontal display area HA1 and a second horizontal line HL2 set in the second horizontal display area HA2.

[0165] The horizontal lines provided in the display panel 110 can be gate lines GL. For example, the first horizontal line HL1 and the second horizontal line HL2 can be gate lines GL. Depending on the structure of one or more sub-pixels SP, the gate lines GL can include several types of gate lines.

[0166] Reference Figure 5A and Figure 5B The vertical lines set in the display panel 110 may include a regular vertical line VLn set only in the regular area NA, a first vertical line VL1 that passes through both the first optical area OA1 and the regular area NA, and a second vertical line VL2 that passes through both the second optical area OA2 and the regular area NA.

[0167] The vertical lines provided in the display panel 110 may include data lines DL, driving voltage lines DVL, etc., and may also include reference voltage lines, initialization voltage lines, etc. For example, the conventional vertical line VLn, the first vertical line VL1, and the second vertical line VL2 may include data lines DL, driving voltage lines DVL, etc., and may also include reference voltage lines, initialization voltage lines, etc.

[0168] In this document, it should be noted that the term "horizontal" in the second horizontal line HL2 can only mean that the signal is transmitted from the left side to the right side (or from the right side to the left side) of the display panel, and does not mean that the second horizontal line HL2 extends in a straight line only in the positive horizontal direction. For example, in Figure 5A and Figure 5B In the diagram, although the second horizontal line HL2 is shown as a straight line, one or more of the second horizontal lines HL2 may include lines that are parallel to each other. Figure 5A and Figure 5B The configuration shown has one or more bends or folds. Similarly, one or more of the first horizontal lines HL1 may also include one or more bends or folds.

[0169] In this document, it should be noted that the term "vertical" in the context of a conventional vertical line VLn can only mean that the signal is transmitted from the top to the bottom (or from the bottom to the top) of the display panel, and does not mean that the conventional vertical line VLn extends in a straight line only in the positive vertical direction. For example, in Figure 5A and Figure 5B In the diagram, although the conventional vertical line VLn is shown as a straight line, one or more of the conventional vertical lines VLn may include lines that are perpendicular to each other. Figure 5A and Figure 5B The configuration shown has one or more bends or folds. Similarly, one or more of the first vertical lines VL1 and one or more of the second vertical lines VL2 may also include one or more bends or folds.

[0170] Reference Figure 5A The first optical region OA1 included in the first horizontal region HA1 may include a plurality of light-emitting regions EA and a plurality of first transmission regions TA1. In the first optical region OA1, the area outside the plurality of first transmission regions TA1 may include a plurality of light-emitting regions EA.

[0171] Reference Figure 5A In order to improve the transmittance of the first optical region OA1, the first horizontal line HL1 can penetrate the first optical region OA1 while avoiding the plurality of first transmission regions TA1 in the first optical region OA1.

[0172] According to this configuration, each of the first horizontal lines HL1 passing through the first optical region OA1 may include one or more curved or bent portions extending around one or more of the corresponding outer edges of one or more of the plurality of first transmission regions TA1 in the first optical region OA1.

[0173] Therefore, one or more first horizontal lines HL1 disposed in the first horizontal region HA1 and one or more second horizontal lines HL2 disposed in the second horizontal region HA2 can have different shapes or lengths. For example, one or more first horizontal lines HL1 that penetrate the first optical region OA1 and one or more second horizontal lines HL2 that do not penetrate the first optical region OA1 can have different shapes or lengths.

[0174] In addition, in order to improve the transmittance of the first optical region OA1, the first vertical line VL1 can penetrate the first optical region OA1 while avoiding the plurality of first transmission regions TA1 in the first optical region OA1.

[0175] According to this configuration, each of the first vertical lines VL1 passing through the first optical region OA1 may include one or more curved or bent portions extending around one or more of the corresponding outer edges of one or more of the plurality of first transmission regions TA1 in the first optical region OA1.

[0176] For example, one or more first vertical lines VL1 that penetrate the first optical region OA1 and one or more conventional vertical lines VLn that are disposed in the conventional region NA but do not penetrate the first optical region OA1 can have different shapes or lengths.

[0177] Reference Figure 5A The first transmission region TA1 included in the first optical region OA1 in the first horizontal region HA1 can be arranged along the diagonal direction.

[0178] Reference Figure 5A In the first optical region OA1 within the first horizontal region HA1, one or more light-emitting regions EA can be provided between two horizontally adjacent first transmission regions TA1. In the first optical region OA1 within the first horizontal region HA1, one or more light-emitting regions EA can be provided between two vertically adjacent first transmission regions TA1.

[0179] Reference Figure 5A Each of the first horizontal lines HL1 located in the first horizontal region HA1 (e.g., each of the first horizontal lines HL1 that runs through the first optical region OA1) may include one or more curved or bent portions extending around one or more corresponding outer edges of one or more of the first transmission regions TA1.

[0180] Reference Figure 5BThe second optical region OA2 included in the first horizontal region HA1 may include a plurality of light-emitting regions EA and a plurality of second transmission regions TA2. Within the second optical region OA2, the area outside the plurality of second transmission regions TA2 may include a plurality of light-emitting regions EA.

[0181] In one or more aspects, the plurality of emitting regions EA and the plurality of second transmission regions TA2 in the second optical region OA2 can have the same characteristics as... Figure 5A The plurality of light-emitting regions EA and the plurality of first transmission regions TA1 in the first optical region OA1 are in substantially the same position and arrangement.

[0182] In one or more aspects, such as Figure 5B As shown, the plurality of emitting regions EA and the plurality of second transmission regions TA2 in the second optical region OA2 can have the same characteristics as... Figure 5A The different positions and arrangements of the plurality of light-emitting regions EA and the plurality of first transmission regions TA1 in the first optical region OA1.

[0183] For example, refer to Figure 5B The plurality of second transmission regions TA2 in the second optical region OA2 can be arranged horizontally. In this example, the light-emitting region EA may not be placed between two horizontally adjacent second transmission regions TA2. Furthermore, one or more of the light-emitting regions EA in the second optical region OA2 can be placed between vertically adjacent second transmission regions TA2. For example, one or more light-emitting regions EA can be placed between two rows of second transmission regions.

[0184] In one or more aspects, when the first horizontal line HL1 penetrates the second optical region OA2 in the first horizontal region HA1 and the conventional region NA adjacent to the second optical region OA2, the first horizontal line HL1 may have the same characteristics as... Figure 5A The first horizontal line HL1 has a basically the same arrangement.

[0185] In one or more aspects, such as Figure 5B As shown, when the first horizontal line HL1 passes through the second optical region OA2 and the conventional region NA adjacent to the second optical region OA2 in the first horizontal region HA1, the first horizontal line HL1 can have the same characteristics as... Figure 5A The first horizontal line HL1 has a different arrangement.

[0186] This is because Figure 5B The luminescent region EA and the second transmission region TA2 in the second optical region OA2 have the same characteristics as... Figure 5A The first optical region OA1 has different positions and arrangements of the light-emitting region EA and the first transmission region TA1.

[0187] Reference Figure 5B When the first horizontal line HL1 passes through the second optical region OA2 in the first horizontal region HA1 and the conventional region NA adjacent to the second optical region OA2, the first horizontal line HL1 can extend in a straight line without any bends or turns between the vertically adjacent second transmission regions TA2.

[0188] For example, a first horizontal line HL1 may have one or more curved or bent portions in the first optical region OA1, but may not have curved or bent portions in the second optical region OA2.

[0189] In order to improve the transmittance of the second optical region OA2, the second vertical line VL2 can penetrate the second optical region OA2 while avoiding the second transmission region TA2 in the second optical region OA2.

[0190] According to this configuration, each of the second vertical lines VL2 penetrating the second optical region OA2 may include one or more curved or bent portions extending around one or more corresponding outer edges of one or more of the second transmission regions TA2.

[0191] For example, one or more second vertical lines VL2 that penetrate the second optical region OA2 and one or more conventional vertical lines VLn that are set in the conventional region NA but do not penetrate the second optical region OA2 can have different shapes or lengths.

[0192] like Figure 5A As shown, each or more of the first horizontal lines HL1 that pass through the first optical region OA1 may have one or more curved or bent portions extending around one or more corresponding outer edges of one or more of the first transmission regions TA1.

[0193] Therefore, the length of the first horizontal line HL1 that runs through the first optical region OA1 and the second optical region OA2 can be slightly longer than the length of the second horizontal line HL2 that is only set in the regular region NA and does not run through the first optical region OA1 and the second optical region OA2.

[0194] Therefore, the resistance of the first horizontal line HL1 that runs through the first optical region OA1 and the second optical region OA2 (which is referred to as the first resistance) can be slightly larger than the resistance of the second horizontal line HL2 that is only set in the regular region NA and does not run through the first optical region OA1 and the second optical region OA2 (which is referred to as the second resistance).

[0195] Reference Figure 5A and Figure 5BAccording to the light-transmitting structure, since the first optical region OA1, which at least partially overlaps with the first optical electronic device 11, includes a plurality of first transmission regions TA1, and the second optical region OA2, which at least partially overlaps with the second optical electronic device 12, includes a plurality of second transmission regions TA2, the first optical region OA1 and the second optical region OA2 can have a smaller number of sub-pixels per unit area than the conventional region NA.

[0196] Therefore, the number of sub-pixels connected to each or more of the first horizontal line HL1 that runs through the first optical region OA1 and the second optical region OA2 can be different from the number of sub-pixels connected to each or more of the second horizontal line HL2 that is only set in the regular region NA and does not run through the first optical region OA1 and the second optical region OA2.

[0197] The number of sub-pixels connected to each or more of the first horizontal lines HL1 that traverse the first optical region OA1 and the second optical region OA2 (referred to as the first number) may be less than the number of sub-pixels connected to each or more of the second horizontal lines HL2 that are only set in the regular region NA and do not traverse the first optical region OA1 and the second optical region OA2 (referred to as the second number).

[0198] The difference between the first quantity and the second quantity can vary based on the difference between the resolution of each of the first optical region OA1 and the second optical region OA2 and the resolution of the conventional region NA. For example, as the difference between the resolution of each of the first optical region OA1 and the second optical region OA2 and the resolution of the conventional region NA increases, the difference between the first quantity and the second quantity can increase.

[0199] As described above, since the number of sub-pixels connected to each or more of the first horizontal lines HL1 that traverse the first optical region OA1 and the second optical region OA2 (the first number) is less than the number of sub-pixels connected to each or more of the second horizontal lines HL2 that are only located in the regular region NA and do not traverse the first optical region OA1 and the second optical region OA2 (the second number), the area where the first horizontal line HL1 overlaps with one or more other electrodes or lines adjacent to the first horizontal line HL1 can be smaller than the area where the second horizontal line HL2 overlaps with one or more other electrodes or lines adjacent to the second horizontal line HL2.

[0200] Therefore, the parasitic capacitance formed between the first horizontal line HL1 and one or more other electrodes or lines adjacent to the first horizontal line HL1 (referred to as the first capacitance) can be much smaller than the parasitic capacitance formed between the second horizontal line HL2 and one or more other electrodes or lines adjacent to the second horizontal line HL2 (referred to as the second capacitance).

[0201] Considering the magnitude relationship between the first and second resistors (e.g., first resistor ≥ second resistor) and the magnitude relationship between the first and second capacitors (e.g., first capacitor << second capacitor), the resistance-capacitance (RC) value of the first horizontal line HL1, which runs through the first optical region OA1 and the second optical region OA2 (referred to as the first RC value), can be much smaller than the RC value of the second horizontal line HL2, which is only set in the conventional region NA and does not run through the first and second optical regions OA1 and OA2 (referred to as the second RC value). Therefore, in this example, the first RC value is much smaller than the second RC value (e.g., first RC value << second RC value).

[0202] Due to the difference between the first RC value of the first horizontal line HL1 and the second RC value of the second horizontal line HL2 (which is called the RC load difference), the signal transmission characteristics through the first horizontal line HL1 can be different from those through the second horizontal line HL2.

[0203] In the following text, for ease of explanation, at least one of the first optical region OA1 and the second optical region OA2 may be described as optical region OA, and at least one of the plurality of first transmission regions TA1 in the first optical region OA1 and the plurality of second transmission regions TA2 in the second optical region OA2 may be described as transmission region TA.

[0204] Figure 6 and Figure 7 An exemplary configuration of the optical region in a display panel 110 according to aspects of this disclosure is shown.

[0205] Figure 6 A plan view illustrating an exemplary arrangement of lenses disposed in an optical region OA (e.g., the first optical region OA1 or the second optical region OA1 discussed above) according to aspects of this disclosure. Figure 7 A more detailed plan view is provided to illustrate an exemplary arrangement of lenses disposed in the optical region OA according to aspects of this disclosure.

[0206] Reference Figure 6 and Figure 7In one or more exemplary embodiments, the optical region OA may include a plurality of transmissive regions TA and a plurality of luminescent regions EA, and overlap with at least one of the optical electronic devices (e.g., the first optical electronic device 11 and the second optical electronic device 12 discussed above) disposed below or at the lower part of the display panel 110.

[0207] For example, when the optical region OA is the first optical region OA1, the optical region OA can overlap with the first optical electronic device 11. Furthermore, when the optical region OA is the second optical region OA2, the optical region OA can overlap with the second optical electronic device 12.

[0208] For example, a plurality of light-emitting regions EA may include at least one red sub-pixel, at least one green sub-pixel, and at least one blue sub-pixel, but this disclosure is not limited thereto. For example, a plurality of light-emitting regions EA may include at least one sub-pixel selected from red, green, and blue sub-pixels, or may include one or more sub-pixels of one or more colors other than red, green, and blue sub-pixels.

[0209] The optical region OA may include a plurality of lenses CL that overlap with a plurality of transmission regions TA. The plurality of lenses CL may be, for example, light-collecting lenses capable of focusing external light incident on at least one of the optical electronic devices (11 and 12) overlapping with the optical region OA onto the plurality of transmission regions TA.

[0210] In one or more aspects, Figure 6 and Figure 7 The plurality of lenses CL in the examples may have circular or rectangular shapes in a plan view, but this disclosure is not limited thereto. For example, the plurality of lenses CL may have polygonal shapes other than circular or rectangular shapes.

[0211] In one or more aspects, the optical region OA may include a plurality of transmissive regions TA to enable optical electronics (11 or 12) disposed below or beneath the display panel 110 to receive external light. In this configuration, the plurality of transmissive regions TA may be extended to improve the performance of the optical electronics (11 or 12).

[0212] However, when multiple transmission regions TA are extended, the display quality of the image presented by the light-emitting regions EA in the optical region OA may deteriorate. For example, since multiple light-emitting regions EA and multiple transmission regions TA on the optoelectronic device (11 or 12) are arranged in a grid configuration, image artifacts such as blurring may occur, and the operating performance of the optoelectronic device (11 or 12) may deteriorate.

[0213] To address this problem, in one or more aspects, the display device 100 may include a structure in which a plurality of lenses CL are arranged to overlap with a plurality of transmission regions TA in an optical region OA, thereby providing the advantage of solving or preventing display quality degradation, image artifacts such as blurring, and deterioration of the operating performance of optoelectronic devices (11 or 12).

[0214] The number of lenses CL can be, for example, the same as the number of transmission regions TA. For instance, a plurality of lenses CL can be positioned on a plurality of transmission regions TA based on a one-to-one matching. Therefore, the efficiency of focusing external light onto the plurality of transmission regions TA can be maximized using a plurality of lenses CL. Furthermore, each of the plurality of lenses CL can be larger than each of the plurality of transmission regions TA, but the implementation is not limited to this.

[0215] For example, the display device 100 can maximize the efficiency of guiding external light to the transmission region TA while minimizing or preventing the propagation of external light to the light-emitting region EA by optimizing the arrangement of a plurality of lenses CL in the optical region OA.

[0216] For example, a plurality of lenses CL can be refractive lenses with a predetermined refractive index.

[0217] For example, when the plurality of lenses CL are refractive lenses, the refractive index can be from 1.5 to 1.8 (e.g., 1.65), but this disclosure is not limited thereto. For example, the plurality of lenses CL can be designed to have a refractive index of 1.8 or higher, or a refractive index of 1.5 or lower.

[0218] Reference Figure 7 In one or more exemplary embodiments, the optical region OA may include a first transmission region to a sixth transmission region (TA_1, TA_2, TA_3, TA_4, TA_5 and TA_6) and a first light-emitting region to a fourth light-emitting region (EA1, EA2, EA3 and EA4) disposed between the first transmission region to the sixth transmission region (TA_1, TA_2, TA_3, TA_4, TA_5 and TA_6).

[0219] It should be noted that, although Figure 7 For ease of illustration, six transmission regions TA and four light-emitting regions EA are shown disposed in the optical region OA; however, aspects of this disclosure are not limited thereto. For example, the optical region OA may include six or more transmission regions TA and four or more light-emitting regions EA.

[0220] Reference Figure 7The first to fourth light-emitting regions (EA1, EA2, EA3 and EA4) can be set as follows: the first light-emitting region EA1 can be set between the first transmission region TA_1 and the second transmission region TA_2; the second light-emitting region EA2 can be set between the second transmission region TA_2 and the third transmission region TA_3; the third light-emitting region EA3 can be set between the fourth transmission region TA_4 and the fifth transmission region TA_5; and the fourth light-emitting region EA4 can be set between the fifth transmission region TA_5 and the sixth transmission region TA_6.

[0221] The optical region OA may include a first lens to a sixth lens (CL1, CL2, CL3, CL4, CL5, and CL6) that overlap with the first to sixth transmission regions (TA_1, TA_2, TA_3, TA_4, TA_5, and TA_6), respectively. According to one embodiment, the centers of the first to sixth lenses may be aligned with and overlap with the centers of the first to sixth transmission regions, but the embodiment is not limited thereto.

[0222] For example, the first lens CL1 can overlap with the first transmission region TA_1, the second lens CL2 can overlap with the second transmission region TA_2, and the third lens CL3 can overlap with the third transmission region TA_3.

[0223] Furthermore, the fourth lens CL4 can overlap with the fourth transmission region TA_4, the fifth lens CL5 can overlap with the fifth transmission region TA_5, and the sixth lens CL6 can overlap with the sixth transmission region TA_6.

[0224] Reference Figure 7 The respective central axis of each of the first to sixth lenses (CL1, CL2, CL3, CL4, CL5 and CL6) may be configured to align with one or more central axes of the first to sixth transmission regions (TA_1, TA_2, TA_3, TA_4, TA_5 and TA_6), but this disclosure is not limited thereto.

[0225] Each of the first to fourth light-emitting regions (EA1, EA2, EA3, and EA4) may overlap with at least two or more lenses.

[0226] For example, the first light-emitting region EA1 can be configured such that at least a portion of the first lens CL1 overlaps with a first region of the first light-emitting region EA1, and at least a portion of the second lens CL2 overlaps with a second region of the first light-emitting region EA1 having the same area as the first region of the first light-emitting region EA1.

[0227] The second light-emitting region EA2 can be configured such that at least a portion of the second lens CL2 overlaps with the first region of the second light-emitting region EA2, and at least a portion of the third lens CL3 overlaps with the second region of the second light-emitting region EA2 having the same area as the first region of the second light-emitting region EA2.

[0228] The third light-emitting region EA3 can be configured such that at least a portion of the fourth lens CL4 overlaps with the first region of the third light-emitting region EA3, and at least a portion of the fifth lens CL5 overlaps with the second region of the third light-emitting region EA3 having the same area as the first region of the third light-emitting region EA3.

[0229] The fourth light-emitting region EA4 can be configured such that at least a portion of the fifth lens CL5 overlaps with the first region of the fourth light-emitting region EA4, and at least a portion of the sixth lens CL6 overlaps with the second region of the fourth light-emitting region EA4 having the same area as the first region of the fourth light-emitting region EA4.

[0230] For example, when the length of each of the first to fourth light-emitting regions (EA1, EA2, EA3 and EA4) in the direction of setting the first to third transmission regions (TA_1, TA_2 and TA_3) is “l”, the length of each of the first and second regions can be “l / 2”, but this disclosure is not limited thereto.

[0231] For example, each of the first to sixth lenses (CL1, CL2, CL3, CL4, CL5 and CL6) can be designed to have a region that overlaps with a complete transmission region and at least corresponding portions of two light-emitting regions adjacent to a transmission region.

[0232] Figure 8 An exemplary lens implemented using a refractive lens is shown, which is disposed in an optical region OA (e.g., the first optical region OA1 or the second optical region OA2 discussed above) according to aspects of this disclosure.

[0233] Reference Figure 8 In one or more exemplary embodiments, the display device 100 may include a plurality of lenses CL disposed on a plurality of transmissive regions TA and overlapping one-to-one with the plurality of transmissive regions TA in an optical region OA, the optical region OA including a plurality of transmissive regions TA and a plurality of luminescent regions EA overlapping with the first optoelectronic device 11.

[0234] It should be noted that, for ease of explanation, although Figure 8An example is shown in which the optical region OA is the first optical region OA1 and a plurality of transmission regions TA and a plurality of light-emitting regions EA overlap the first optoelectronic device 11; however, the aspects of this disclosure are not limited thereto. For example, when Figure 8 When the optical region OA is the second optical region OA2, the plurality of transmission regions TA and the plurality of light-emitting regions EA can overlap the second optical electronic device 12.

[0235] The plurality of lenses CL can be refractive lenses with a predetermined refractive index. In this embodiment, the plurality of lenses CL can focus external light incident toward the first optical electronic device 11 onto the plurality of transmission regions TA respectively. According to one embodiment, the interface between two adjacent lenses CL can overlap with the center of the light-emitting region EA, but the embodiment is not limited to this.

[0236] Multiple lenses CL can also be used to diffuse the light output from multiple light-emitting regions EA.

[0237] Figure 9 An exemplary lens implemented using a polarizing lens is shown, which is disposed in an optical region OA (e.g., the first optical region OA1 or the second optical region OA2 discussed above) according to aspects of this disclosure.

[0238] Reference Figure 9 In one or more exemplary embodiments, the display device 100 may include a plurality of lenses CL disposed on a plurality of transmissive regions TA and overlapping one-to-one with the plurality of transmissive regions TA in an optical region OA, the optical region OA including a plurality of transmissive regions TA and a plurality of luminescent regions EA overlapping with the first optoelectronic device 11.

[0239] It should be noted that, for ease of explanation, although Figure 9 An example is shown in which the optical region OA is the first optical region OA1 and a plurality of transmission regions TA and a plurality of light-emitting regions EA overlap the first optoelectronic device 11; however, the aspects of this disclosure are not limited thereto. For example, when Figure 9 When the optical region OA is the second optical region OA2, the plurality of transmission regions TA and the plurality of light-emitting regions EA can overlap the second optical electronic device 12.

[0240] For example, the plurality of lenses CL can be polarizing lenses (e.g., liquid crystal polarizing lenses) capable of converting first circularly polarized light (external light) into second circularly polarized light and focusing the second circularly polarized light onto the plurality of transmission regions TA respectively. The plurality of lenses CL can be Pancharatnam-Berry optical lenses, or lenses that operate in a similar manner, but aspects of this disclosure are not limited thereto.

[0241] For example, the first circularly polarized light can be right-handed circularly polarized light, and the second circularly polarized light can be left-handed circularly polarized light.

[0242] In an example where the plurality of lenses CL are polarizing lenses, the display device 100 may further include a first polarizing plate 910 disposed on the plurality of lenses and a second polarizing plate 920 disposed on the first polarizing plate 910. The first polarizing plate 910 and the second polarizing plate 920 may overlap both the optical region OA and the conventional region NA.

[0243] For example, the first polarizing plate 910 can be a circular polarizing plate, and the second polarizing plate 920 can be a linear polarizing plate. For example, the first polarizing plate 910 can be a λ / 4 phase retardation film (e.g., a quarter-wave plate (QWP)), but the aspects of this disclosure are not limited thereto.

[0244] Figures 10A to 10D An exemplary configuration of a plurality of lenses implemented using polarizing lenses is shown in an optical region OA (e.g., the first optical region OA1 or the second optical region OA2 discussed above) according to aspects of this disclosure.

[0245] Figure 10A An example is shown in which the lens CL is implemented using a liquid crystal polarizing lens. Figure 10B The optical characteristics of the liquid crystal polarizing lens are shown. Figure 10C The light-gathering characteristics of the liquid crystal polarizing lens are shown. Figure 10D The diffuse characteristic of the optical properties of the liquid crystal polarizing lens is shown.

[0246] Reference Figure 10A In one or more exemplary embodiments, the display device 100 may include a plurality of transmission regions TA disposed on optical regions OA and based on a plurality of lenses CL overlapping one-to-one with the plurality of transmission regions TA, and the plurality of lenses CL may be, for example, liquid crystal polarizing lenses.

[0247] In one or more aspects, a plurality of lenses CL implemented using liquid crystal polarizing lenses can control the arrangement of a plurality of liquid crystals according to an externally applied electric field. For example, the plurality of lenses CL can convert a first circularly polarized light (e.g., right-handed circularly polarized light) into a second circularly polarized light (e.g., left-handed circularly polarized light) or convert a second circularly polarized light into a first circularly polarized light.

[0248] Reference Figure 10B and Figure 10CA plurality of lenses CL implemented using liquid crystal polarizing lenses can convert a first circularly polarized light CP1 into a second circularly polarized light CP2, and can also focus the second circularly polarized light CP2. For example, each of the plurality of lenses CL can perform two operations, such as rotating the light in opposite directions and bending the light so that they meet at a single point (e.g., the focal point).

[0249] Reference Figure 10B and Figure 10D A plurality of lenses CL, implemented using liquid crystal polarizing lenses, can convert second circularly polarized light CP2 into first circularly polarized light CP1, while simultaneously diffusing the first circularly polarized light CP1. For example, each of the plurality of lenses CL can perform two operations, such as rotating the light in opposite directions and diffusing the light so that it is scattered rather than concentrated or focused.

[0250] Figure 11 Exemplary light output characteristics of a plurality of lenses implemented using polarizing lenses, arranged in an optical region OA (e.g., the first optical region OA1 or the second optical region OA2 discussed above), according to aspects of this disclosure, are shown.

[0251] Reference Figure 11 In one or more exemplary embodiments, in the display device 100, light OL output from the light-emitting region EA in the optical region OA can be directed to the second polarizing plate 920.

[0252] For example, the light OL output from the emitting region EA can be light that vibrates randomly (e.g., light in a random polarization state).

[0253] For example, light OL emitted from the light-emitting region EA can pass through the lens CL and the first polarizing plate 910, and then enter the second polarizing plate 920. In this case, the lens CL and the first polarizing plate 910 can remain unaffected by the polarization state of the light OL emitted from the light-emitting region EA.

[0254] In contrast, the second polarizing plate 920 can convert light OL from the light-emitting region EA into linearly polarized light LL. For example, the linearly polarized light LL can have an electric field that oscillates in a single fixed plane perpendicular to the direction of light propagation.

[0255] The first polarizing plate 910 and the second polarizing plate 920 can be configured to overlap not only with the optical region OA but also with the conventional region NA. According to this configuration, the second polarizing plate 920 can also convert light OL emitted from the light-emitting region EA located in the conventional region NA into linearly polarized light LL.

[0256] Figure 12Exemplary light-receiving characteristics of a plurality of lenses implemented using polarizing lenses, arranged in an optical region OA (e.g., the first optical region OA1 or the second optical region OA2 discussed above) according to aspects of this disclosure are shown.

[0257] Reference Figure 12 In one or more exemplary embodiments, the display device 100 can control the polarization state of external light incident on an optical electronic device (e.g., a first optical electronic device 11 or a second optical electronic device 12) via a second polarizing plate 920, a first polarizing plate 910 and a lens CL, while focusing the external light with the controlled polarization state onto the transmission region TA.

[0258] The second polarizing plate 920 can convert external light IL into linearly polarized light LL, and the first polarizing plate 910 can convert linearly polarized light LL into first circularly polarized light CP1.

[0259] The lens CL can convert the first circularly polarized light CP1 into the second circularly polarized light CP2, and simultaneously focus the second circularly polarized light CP2 onto the transmission region TA.

[0260] Figure 13 An exemplary formation of an optical region OA (e.g., the first optical region OA1 or the second optical region OA2 discussed above) according to aspects of this disclosure is shown.

[0261] Reference Figure 13 In one or more exemplary embodiments, the display device 100 may include an optical region OA, the optical region OA including a plurality of light-emitting regions EA and a plurality of transmissive regions TA overlapping with the first optical electronics 11; and a first encapsulation layer PCL1, a plurality of lenses CL and a second encapsulation layer PCL2, which overlap with the optical region OA.

[0262] It should be noted that, for ease of explanation, although Figure 13 An example is shown in which the optical region OA is a first optical region OA1 and a plurality of transmission regions TA and a plurality of light-emitting regions EA overlap in a first optoelectronic device 11; however, the aspects of this disclosure are not limited thereto. For example, in which... Figure 13 In an example where the optical region OA is the second optical region OA2, a plurality of transmission regions TA and a plurality of light-emitting regions EA can overlap the second optical electronic device 12.

[0263] For example, a first encapsulation layer PCL1 can be disposed on a plurality of light-emitting regions EA and a plurality of transmissive regions TA, a plurality of lenses CL can be disposed on the first encapsulation layer PCL1, and a second encapsulation layer PCL2 can be disposed on a plurality of lenses CL.

[0264] For example, an adhesive layer can be provided between the first encapsulation layer PCL1 and the plurality of lenses CL. This can improve the adhesive strength between the first encapsulation layer PCL1 and the plurality of lenses CL.

[0265] In one or more aspects, the display device 100 may further include a substrate and a planarization layer disposed on the substrate. In this configuration, a plurality of light-emitting regions EA located in each of the optical region OA and the conventional region NA, and a plurality of transmissive regions TA located in the optical region OA may be disposed on the planarization layer.

[0266] For example, a plurality of first light-emitting elements corresponding to a plurality of light-emitting regions EA located in the optical region OA and a plurality of second light-emitting elements corresponding to a plurality of light-emitting regions EA located in the conventional region NA can be provided on the planarization layer.

[0267] For example, a plurality of first light-emitting elements in the optical region OA and a plurality of second light-emitting elements in the conventional region NA can be formed in the same layer. However, according to another embodiment, the plurality of first light-emitting elements in the optical region OA and the plurality of second light-emitting elements in the conventional region NA can be formed on different layers.

[0268] In one or more aspects, the display device 100 may further include a cover glass disposed on the second encapsulation layer PCL2. In this configuration, an adhesive layer may be disposed between the second encapsulation layer PCL2 and the cover glass, thereby improving the adhesive strength between the second encapsulation layer PCL2 and the cover glass.

[0269] Figure 14 An exemplary stacked structure of a display device 100 according to aspects of this disclosure is shown.

[0270] Reference Figure 14 In one or more exemplary embodiments, the display device 100 may include a nontransmissive region NTA and at least one transmissive region TA in an optical region OA (e.g., the first optical region OA1 or the second optical region OA2 discussed above).

[0271] The non-transmissive region NTA may be included in both the optical region OA and the conventional region NA, and the non-transmissive region NTA included in the optical region OA and the conventional region NA may include a plurality of luminescent regions EA in each of the optical region OA and the conventional region NA.

[0272] Although Figure 14 For ease of illustration, an example is shown in which the transmission region TA of the optical region OA overlaps with the first optical electronic device 11; however, the aspects of this disclosure are not limited thereto. For example, the transmission region TA of the optical region OA may also overlap with the second optical electronic device 12.

[0273] In addition, although Figure 14 The first optical electronic device 11 overlaps with the transmission region TA of the optical region OA, but the optical electronic device 11 may also overlap with a portion of the non-transmission region NTA included in the optical region OA.

[0274] The non-transmissive region NTA and the transmissive region TA can both include a substrate SUB, a transistor layer TRL, a planarization layer PLN, a light-emitting element layer EDL, an encapsulation layer ENCAP, a touch sensor layer TSL, and a protective layer PAC.

[0275] In the following text, refer to Figure 14 Describe the stacking structure of the non-transmissive region NTA.

[0276] The substrate SUB may include a first substrate SUB1, an interlayer insulating layer IPD, and a second substrate SUB2. The interlayer insulating layer IPD may be located between the first substrate SUB1 and the second substrate SUB2. Because the substrate SUB includes the first substrate SUB1, the interlayer insulating layer IPD, and the second substrate SUB2, moisture penetration can be effectively prevented. For example, the first substrate SUB1 and the second substrate SUB2 may be polyimide (PI) substrates.

[0277] The transistor layer TRL can be configured with several patterns (e.g., ACT, SD1, GATE), several insulating layers (e.g., MBUF, ABUF1, ABUF2, GI, ILD1, ILD2, PAS0), and several metal patterns (e.g., TM, GM, ML1, ML2) to form one or more transistors, such as the driver transistor DRT.

[0278] The stacking structure of the transistor layer (TRL) will be described in more detail below.

[0279] A multi-buffer layer MBUF can be provided on the second substrate SUB2, and a first active buffer layer ABUF1 can be provided on the multi-buffer layer MBUF.

[0280] A first metal layer ML1 and a second metal layer ML2 can be disposed on the first active buffer layer ABUF1. For example, each of the first metal layer ML1 and the second metal layer ML2 can be used as a light shield.

[0281] A second active buffer layer ABUF2 can be disposed on the first metal layer ML1 and the second metal layer ML2. An active layer ACT for driving the DRT transistor can be disposed on the second active buffer layer ABUF2.

[0282] The gate insulating layer GI can be configured to cover the active layer ACT.

[0283] The gate electrode GATE of the driving transistor DRT can be disposed on the gate insulating layer GI. In this configuration, at a location different from where the driving transistor DRT is disposed, the gate material layer GM along with the gate electrode GATE of the driving transistor DRT can be disposed on the gate insulating layer GI.

[0284] A first interlayer insulating layer (ILD1) can be provided such that it covers the gate electrode (GATE) and the gate material layer (GM). A metal pattern (TM) can be provided on the first interlayer insulating layer (ILD1). A second interlayer insulating layer (ILD2) can be provided such that it covers the metal pattern (TM) on the first interlayer insulating layer (ILD1).

[0285] Two first source-drain electrode patterns SD1 can be formed on the second interlayer insulating layer ILD2. One of the two first source-drain electrode patterns SD1 can be the source node of the driving transistor DRT, and the other can be the drain node of the driving transistor DRT.

[0286] Two first source-drain electrode patterns SD1 can be connected to the first side and the second opposite side of the active layer ACT through contact holes in the second interlayer insulating layer ILD2, the first interlayer insulating layer ILD1, and the gate insulating layer GI, respectively. The portion of the active layer ACT that overlaps with the gate electrode GATE can be defined as the channel region. One of the two first source-drain electrode patterns SD1 can be connected to the first side of one side of the channel region of the active layer ACT, and the other of the two first source-drain electrode patterns SD1 can be connected to the second opposite side of the channel region of the active layer ACT.

[0287] A passivation layer PAS0 can be set to cover the two first source-drain electrode patterns SD1.

[0288] A planarization layer PLN can be set on the transistor layer TRL. The planarization layer PLN may include a first planarization layer PLN1 and a second planarization layer PLN2.

[0289] A first planarization layer PLN1 can be disposed on a passivation layer PAS0. A second source-drain electrode pattern SD2 can be disposed on the first planarization layer PLN1. The second source-drain electrode pattern SD2 can be connected to one of the two first source-drain electrode patterns SD1 through the contact holes of the first planarization layer PLN1 (which can correspond to...). Figure 3 The second node N2 in the middle.

[0290] A second planarization layer PLN2 can be set to cover the second source-drain electrode pattern SD2. A light-emitting element layer EDL can be set on the second planarization layer PLN2.

[0291] The light-emitting element layer (EDL) may include a light-emitting element (ED) formed by a pixel electrode (PE), a light-emitting layer (EL), and a common electrode (CE). The light-emitting layer (EL) may include an organic layer.

[0292] For example, Figure 14 The light-emitting element ED can be a first light-emitting element in at least one of the light-emitting regions EA formed in the optical region OA, or a second light-emitting element in at least one of the light-emitting regions EA formed in the conventional region NA.

[0293] The pixel electrode PE can be disposed on the second planarization layer PLN2, and the pixel electrode PE can be electrically connected to the second source-drain electrode pattern SD2 through the contact holes of the second planarization layer PLN2.

[0294] A dam can be configured to cover the pixel electrode PE. The dam can have an opening that corresponds to a portion of the light-emitting area of ​​the corresponding sub-pixel SP. A portion of the pixel electrode PE can be exposed through the opening of the dam. A light-emitting layer EL can be disposed within the opening of the dam and on the periphery surrounding the opening. Therefore, the light-emitting layer EL can be disposed on the pixel electrode PE exposed through the opening of the dam.

[0295] The common electrode CE can be disposed on the light-emitting layer EL. For example, the common electrode CE can be a cathode electrode.

[0296] The encapsulation layer ENCAP can be set on the light-emitting element layer EDL.

[0297] The ENCAP encapsulation layer can have a single-layer or multi-layer structure. For example, Figure 14 As shown, the encapsulation layer ENCAP may include a lower encapsulation layer PAS1, a first encapsulation layer PCL1, a second encapsulation layer PCL2, and an upper encapsulation layer PAS2.

[0298] However, the display device 100 according to aspects of this disclosure is not limited thereto. For example, the encapsulation layer ENCAP may consist of only the first encapsulation layer PCL1 and the second encapsulation layer PCL2.

[0299] The lower encapsulation layer PAS1 and the upper encapsulation layer PAS2 can be inorganic layers, and the first encapsulation layer PCL1 and the second encapsulation layer PCL2 can be organic or inorganic layers. The first encapsulation layer PCL1 and the second encapsulation layer PCL2 can be used as planarization layers.

[0300] The lower encapsulation layer PAS1 can be disposed on the common electrode CE and positioned closest to the light-emitting element ED. The lower encapsulation layer PAS1 can contain an inorganic insulating material that allows for low-temperature deposition. For example, the lower encapsulation layer PAS1 can contain silicon nitride (SiNx), silicon oxide (SiOx), silicon oxynitride (SiON), or aluminum oxide (Al2O3). Because the lower encapsulation layer PAS1 is deposited in a low-temperature atmosphere, it can prevent the light-emitting layer EL, which contains organic materials susceptible to high-temperature atmospheres, from being damaged during the deposition process.

[0301] The first encapsulation layer PCL1 and the second encapsulation layer PCL2 may include areas smaller than the lower encapsulation layer PAS1. In this configuration, the first encapsulation layer PCL1 and the second encapsulation layer PCL2 may be formed such that at least one of the ends of the lower encapsulation layer PAS1 is exposed. The first encapsulation layer PCL1 and the second encapsulation layer PCL2 may act as buffers to alleviate stress between one or more layers below or above the display device 100 when it is bent, and may also be used to enhance planarization performance. For example, the first encapsulation layer PCL1 and the second encapsulation layer PCL2 may contain organic insulating materials, such as acrylic resins, epoxy resins, polyimides, polyethylene, silicon-oxygen carbon (SiOC), etc. For example, the first encapsulation layer PCL1 and the second encapsulation layer PCL2 may be formed by an inkjet process.

[0302] In one or more aspects, the display panel 110 may include one or more dams disposed at the end of the inclined surface of the encapsulation layer ENCAP or in a region adjacent to the inclined surface of the encapsulation layer ENCAP to prevent the encapsulation layer ENCAP from collapsing or overflowing. One or more dams may be disposed at the boundary between the display area DA and the non-display area NDA or in a region adjacent to the boundary between the display area DA and the non-display area NDA.

[0303] For example, the first encapsulation layer PCL1 and the second encapsulation layer PCL2, containing organic materials, may be located only on the innermost dam of one or more dams. Alternatively, the first encapsulation layer PCL1 and the second encapsulation layer PCL2 may not be located on all of one or more dams. In contrast, in examples where a first dam and a second dam are provided, the first encapsulation layer PCL1 and the second encapsulation layer PCL2, containing organic materials, may be located on the first dam, which is the innermost dam. For example, the first encapsulation layer PCL1 and the second encapsulation layer PCL2 may extend only to the upper part of the first dam. In another example, the first encapsulation layer PCL1 and the second encapsulation layer PCL2 may extend through the upper part of the first dam to the upper part of the second dam. Furthermore, the portion of the second encapsulation layer PCL2 that overlaps with the lens CL in the transmission region TA may be thinner than the portion of the second encapsulation layer PCL2 in the non-transmission region NTA. For example, the thickness of the second encapsulation layer PCL2 in the transmission region TA may be different from the thickness of the second encapsulation layer PCL2 in the non-transmission region NTA.

[0304] The upper encapsulation layer PAS2 can be disposed on a substrate SUB on which the first encapsulation layer PCL1 and the second encapsulation layer PCL2 are disposed, and is configured such that the upper encapsulation layer PAS2 covers the corresponding upper and side surfaces of the first encapsulation layer PCL1, the second encapsulation layer PCL2, and the lower encapsulation layer PAS1. The upper encapsulation layer PAS2 can minimize or block the permeation of external moisture or oxygen into the lower encapsulation layer PAS1, the first encapsulation layer PCL1, and the second encapsulation layer PCL2. For example, the upper encapsulation layer PAS2 can contain inorganic insulating materials, such as silicon nitride (SiNx), silicon oxide (SiOx), silicon oxynitride (SiON), aluminum oxide (Al2O3), etc.

[0305] A touch sensor layer (TSL) can be set on the encapsulation layer (ENCAP).

[0306] A touch buffer layer (T-BUF) can be placed on the encapsulation layer ENCAP, and a touch sensor (TS) can be placed on the touch buffer layer T-BUF. The touch sensor TS may include a touch sensor metal (TSM) and a bridging metal (BRG) located in different layers. A touch interlayer insulating layer (T-ILD) can be placed between the touch sensor metal (TSM) and the bridging metal (BRG).

[0307] For example, a touch sensor metal TSM may include a first touch sensor metal TSM, a second touch sensor metal TSM, and a third touch sensor metal TSM disposed adjacent to each other. The first and second touch sensor metal TSMs may be electrically connected to each other, and when the third touch sensor metal TSM is located between the first and second touch sensor metal TSMs, the first and second touch sensor metal TSMs may be electrically connected through a bridging metal BRG located in different layers. The bridging metal BRG may be insulated from the third touch sensor metal TSM through a touch interlayer insulating layer (T-ILD).

[0308] During the formation of the touch sensor layer (TSL), chemical solutions (e.g., developer, etchant, etc.) may be used or generated, or external moisture may enter the TSL. By placing a touch buffer layer (T-BUF) on the encapsulation layer (ENCAP) and then placing the TSL on the T-BUF, such chemical solutions or moisture can be prevented from penetrating into the light-emitting layer (EL) containing organic materials during the fabrication of the TSL. Therefore, the T-BUF prevents damage to the EL, which is susceptible to chemical solutions or moisture.

[0309] To prevent damage to the light-emitting layer (EL) containing organic materials susceptible to high temperatures, the touch buffer layer (T-BUF) can be formed at a low temperature below a certain level (e.g., 100 degrees Celsius) and contains an organic insulating material with a low dielectric constant of 1 to 3 (e.g., 2). For example, the touch buffer layer (T-BUF) can contain acrylic, epoxy, or siloxane materials. When the display device 100 is bent, the encapsulation layer (ENCAP) may be damaged, and the touch sensor metal located on the touch buffer layer (T-BUF) may crack. Even when the display device 100 is bent, the touch buffer layer (T-BUF) with planarization properties made of organic insulating material can prevent damage to the encapsulation layer (350) and / or cracking of the metal (TSM and BRG) contained in the touch sensor (TS).

[0310] A protective layer PAC can be set to cover the touch sensor TS. The protective layer PAC can be an organic insulating layer.

[0311] In the following text, refer to Figure 14 Describe the stacked structure of the transmission region TA in the optical region OA.

[0312] Reference Figure 14The substrate SUB and insulating layers (MBUF, ABUF1, ABUF2, GI, ILD1, ILD2, PAS0, PLN (PLN1, PLN2), BANK, and ENCAP (PAS1, PCL1, PCL2, PAS2, T-BUF, T-ILD, PAC) located in the non-transmittent region NTA can also be located in the transmittent region TA in the optical region OA.

[0313] However, apart from the insulating material in the non-transmissive region NTA, material layers with electrical properties (e.g., one or more metal material layers, one or more semiconductor layers, etc.) cannot be disposed in the transmissive region TA.

[0314] For example, the metal material layers (ML1, ML2, GATE, GM, TM, SD1, SD2) associated with the transistor and semiconductor layer ACT cannot be disposed in the transmissive region TA. The pixel electrode PE and common electrode CE included in the light-emitting element ED cannot be disposed in the transmissive region TA. The light-emitting layer EL can be disposed in the transmissive region TA. The touch sensor metal TSM and bridging metal BRG included in the touch sensor TS cannot be disposed in the transmissive region TA.

[0315] Reference Figure 14 The lens CL can be positioned between the first encapsulation layer PCL1 and the second encapsulation layer PCL2 in the transmission region TA.

[0316] The lens CL can be a refractive lens with a predetermined refractive index or a polarizing lens (e.g., a liquid crystal polarizing lens) capable of converting first circularly polarized light into second circularly polarized light or second circularly polarized light into first circularly polarized light.

[0317] Lens CL can be a Pancharatnam-Berry optical lens.

[0318] In an example where the lens CL is a polarizing lens, a first polarizing plate 910 and a second polarizing plate 920 can be provided on the non-transmitting region NTA and the transmitting region TA.

[0319] For example, the first polarizing plate 910 can be a circular polarizing plate, and the second polarizing plate 920 can be a linear polarizing plate.

[0320] For example, the display device 100 may include a structure in which a lens CL, implemented using a polarizing lens, a first polarizing plate 910, and a second polarizing plate 920 overlap each other in the transmission region TA. Thus, in the display device 100, the polarization of external light incident on the optoelectronic device 11 can be converted, and simultaneously, the external light can be focused onto the transmission region TA. In this way, the configuration of the display device 100 can improve its performance by effectively guiding light to the optics under the display without compromising the visual integrity of the display screen or the aesthetic design of the device.
