[0040] In the following description, embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. The description may focus primarily on the parts necessary for understanding operation according to the present disclosure, and descriptions of other parts may be omitted so as not to unnecessarily obscure the subject matter of the disclosure. Furthermore, the present disclosure is not limited to the exemplary embodiments described herein, but may be implemented in various different forms. Rather, the exemplary embodiments described herein are provided to provide a thorough and complete description of the disclosure and to fully convey the concept of the disclosure to those skilled in the art.

[0041] It will be understood that although the terms “first,” “second,” “third,” etc., may be used herein to describe various elements, components, regions, layers, and / or portions, these elements, components, regions, layers, and / or portions should not be limited by these terms. These terms are used to distinguish one element, component, region, layer, or portion from another element, component, region, layer, or portion. Therefore, without departing from the spirit and scope of the inventive concept, the first element, first component, first region, first layer, or first portion discussed below may be referred to as a second element, second component, second region, second layer, or second portion.

[0042] It will also be understood that when a layer is referred to as being "between" two layers, it can be the only layer between the two layers, or there can be one or more intervening layers.

[0043] The terminology used herein is for the purpose of describing particular embodiments and is not intended to limit the inventive concept. As used herein, the singular forms “a” and “an” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will also be understood that the terms “comprising,” “including,” “containing,” “having,” “having,” and “having,” when used in this specification, designate the presence of stated features, integrals, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or groups thereof.

[0044] As used herein, the term “and / or” includes any and all combinations of one or more of the related listed items. For example, the expression “A and / or B” means A, B, or A and B. Expressions such as “one or more of…” and “at least one of…” modify the entire list of elements rather than individual elements in the list when they follow a list of elements. For example, the expressions “one or more of A, B, and C,” “at least one of A, B, and C,” and “at least one selected from the group consisting of A, B, and C” indicate only A, only B, only C, both A and B, both A and C, both B and C, or all of A, B, and C.

[0045] Furthermore, the use of "may" when describing embodiments of the inventive concept indicates "one or more embodiments of the inventive concept". Additionally, the term "exemplary" is intended to indicate an example or illustration.

[0046] It will be understood that when an element or layer is referred to as being "on" another element or layer, "connected" to another element or layer, "attached" to another element or layer, or "adjacent" to another element or layer, it may be directly on, directly connected to, directly attached to, or directly adjacent to another element or layer, or one or more intervening elements or layers may exist. When an element or layer is referred to as being "directly on" another element or layer, "directly connected" to another element or layer, "directly attached" to another element or layer, "in contact" with another element or layer, "in direct contact" with another element or layer, or "immediately adjacent" to another element or layer, there is no intervening element or layer.

[0047] As used herein, the terms “use,” “using,” and “used” can be considered synonymous with the terms “utilize,” “utilizing,” and “utilized,” respectively.

[0048] For ease of description, spatially relative terms such as “below” and “above” may be used herein to describe the relationship between one element and another as shown in the figures. It will also be understood that, in addition to the orientations described herein and depicted in the figures, the spatially relative terms and illustrated configurations are intended to cover different orientations of the device in use or operation. For example, if the device in the figure is flipped, an element described as “below” or “under” other elements or features will then be oriented “above” other elements or features. Thus, the exemplary term “above” can cover both above and below orientations. The device may be oriented in other ways (e.g., rotated 90 degrees or oriented in other directions), and the spatially relative descriptive terms used herein may be interpreted accordingly.

[0049] Furthermore, embodiments of this disclosure are described herein with reference to schematic diagrams of preferred embodiments (and intermediate structures), thereby allowing for the anticipation of deviations in the illustrated shapes due to, for example, manufacturing techniques and / or tolerances. Therefore, embodiments of this disclosure should not be limited to the specific shapes of the regions shown herein, but rather include shape deviations caused, for example, by manufacturing techniques. The regions shown in the accompanying drawings are schematic in nature, and their shapes do not represent the actual shapes of regions of the device, and do not limit the scope of this disclosure.

[0050] Figure 1 and Figure 2 This is a view showing a display device according to some embodiments of the present disclosure.

[0051] refer to Figure 1 and Figure 2 The display device DD may include a display module 100 and accessories 200.

[0052] The display module 100 may include a protective layer 110, a window 120, a polarizing plate 130, a panel 140, a plate 150, an adhesive layer 160, a printed circuit board 170, and a display connector 180.

[0053] Accessory 200 may include accessory body 210 and accessory connector 220.

[0054] The protective layer 110 is a protective component disposed at the top of the display module 100, and may be a substantially transparent light-transmitting substrate. The protective layer 110 can protect the components disposed below the protective layer 110 from external factors (e.g., penetration of external moisture and oxygen, external physical impact, etc.).

[0055] Window 120 may be configured to overlap with protective layer 110. Window 120 may be a substantially transparent light-transmitting substrate. Window 120 may have a multilayer structure selected from glass substrates, plastic films, and plastic substrates. Window 120 may include rigid or flexible base materials, and there are no particular limitations on the materials constituting window 120.

[0056] Polarizing plate 130 can be configured to overlap with window 120. Polarizing plate 130 can be attached to the outer surface of panel 140 to improve environmental visibility, such as by blocking external light reflection. Polarizing plate 130 and panel 140 can be manufactured separately and then attached or assembled to each other.

[0057] Panel 140 can be configured to overlap with polarizer 130. (See later for reference.) Figures 3 to 5 A more detailed description of panel 140 is provided.

[0058] Plate 150 may be configured to overlap with panel 140. Plate 150 may comprise a metallic material (e.g., aluminum). Plate 150 may protect panel 140 from external impacts (e.g., external physical impacts). In some embodiments, plate 150 may have various suitable thicknesses on the third-direction DR3.

[0059] An adhesive layer 160 may be disposed between board 150 and printed circuit board 170. Board 150 may be adhered to printed circuit board 170 via adhesive layer 160.

[0060] Adhesive layer 160 may include a first adhesive layer 161 (e.g., see...) Figure 6 ) and the second adhesive layer 162 (for example, see Figure 6 (See below for reference) Figure 6 The first adhesive layer 161 and the second adhesive layer 162 are described.

[0061] The printed circuit board 170 can be configured to overlap with the adhesive layer 160. The printed circuit board 170 can receive external signals from the accessory 200 to generate signals for driving multiple pixel PXs (e.g., see...). Figure 3 The printed circuit board 170 can also drive the panel 140 to sense touch. (See later...) Figure 4 and Figure 5 To describe it in more detail.

[0062] One side of the display connector 180 can be connected to the printed circuit board 170. One side of the accessory connector 220 can be connected to the accessory body 210. The other side of the display connector 180 can be electrically connected to the other side of the accessory connector 220. The printed circuit board 170 and the accessory body 210 can be connected to each other via the electrical connection between the display connector 180 and the accessory connector 220. The printed circuit board 170 can receive external signals (e.g., vertical synchronization signal Vsync (see [link to documentation]) via the display connector 180 and the accessory connector 220). Figure 5 )wait).

[0063] The display connector 180 and accessory connector 220 may include flexible material. The display connector 180 and accessory connector 220 can be bent at a predetermined curvature.

[0064] Accessory body 210 can provide external signals (e.g., vertical synchronization signal Vsync, etc.) to printed circuit board 170 through accessory connector 220 and display connector 180.

[0065] In the process of fastening (or electrically connecting) the accessory connector 220 and the display connector 180 to each other, unintended pressure may be applied to the printed circuit board 170 and the adhesive layer 160 (see arrow). Furthermore, the printed circuit board 170 and the adhesive layer 160 may include pressure-bearing areas PR to which unintended pressure is applied. In this process, the pressure applied to the printed circuit board 170 and the adhesive layer 160 may be transmitted to the protective layer 110. Furthermore, the protective layer 110 may be damaged by the pressure (e.g., crushed).

[0066] The display module 100 according to embodiments of this disclosure can reduce (e.g., minimize) the pressure transmitted upwards through the adhesive layer 160 to the protective layer 110. Therefore, damage to the protective layer 110 can be prevented or substantially reduced. Reference will be made later. Figure 9 , Figure 11 and Figure 12 To describe it in more detail.

[0067] Figure 3 This illustrates some embodiments according to the present disclosure. Figure 1 A schematic diagram of the display device's panel and printed circuit board.

[0068] refer to Figure 1 and Figure 3 Panel 140 may include touch array 141 and display panel 142 overlapping touch array 141. Printed circuit board 170 may include touch driver 171, display driver 172, etc.

[0069] The touch array 141 may include an active touch-sensing area SA and an inactive touch-sensitive area NSA surrounding the active touch area SA. The active touch area SA may at least partially overlap with the display area DA.

[0070] Touch array 141 may include a substrate and touch electrodes formed on the substrate. In some embodiments, the touch electrodes may include a driving electrode TX and a sensing electrode RX. The driving electrode TX may include a first cell CL1. The sensing electrode RX may include a second cell CL2. The driving electrode TX and the sensing electrode RX may be disposed on the substrate in an effective region SA. In some embodiments, the substrate may be a rigid substrate comprising a material such as glass or tempered glass. In some other embodiments, the substrate may be a flexible substrate comprising a material such as plastic or metal. In some embodiments, at least one layer included in the display panel 142 may be used as the substrate of touch array 141.

[0071] In some embodiments, the touch array 141 and the display panel 142 may be manufactured separately from each other and then joined together to at least partially overlap each other. In some other embodiments, the touch array 141 and the display panel 142 may be manufactured integrally. The touch array 141 may be formed directly on at least one layer included in the display panel 142 (e.g., an upper substrate, thin-film encapsulation layer, or insulating layer of the display panel 142).

[0072] exist Figure 3 The image shows a touch array 141 disposed on the display panel 142. However, the touch array 141 is not limited to this. For example, the touch array 141 may be disposed below the display panel 142.

[0073] Display panel 142 may include a display area DA for displaying an image and a non-display area NDA surrounding the display area DA. The non-display area NDA may at least partially surround the display area DA. Display panel 142 may include pixels PX formed on a substrate. Pixels PX may be disposed within the display area DA. In some embodiments, the substrate may be a rigid substrate comprising a material such as glass or tempered glass. In some other embodiments, the substrate may be a flexible substrate comprising a material such as plastic or metal.

[0074] Pixel PX is connected to drive line SL and data line DL. Pixel PX is selected by a drive signal with a conduction level provided via drive line SL, and pixel PX receives a data signal via data line DL. Therefore, pixel PX emits light with a brightness corresponding to the data signal and displays an image in display area DA.

[0075] The lines and / or built-in circuitry connected to the pixel PX can be located in the non-display area NDA. For example, the scan driver can be further located in the non-display area NDA.

[0076] In some embodiments, the display panel 142 may include organic light-emitting diodes, inorganic light-emitting diodes, quantum dot / quantum well light-emitting diodes, etc., as pixels (PX). In other embodiments, the display panel 142 may be implemented as a liquid crystal display panel. A light source, such as a backlight unit, may also be included.

[0077] In some embodiments, the touch driver 171 and the display driver 172 may be configured as separate integrated circuits (ICs). In other embodiments, the touch driver 171 and the display driver 172 may be housed in a single IC.

[0078] Touch driver 171 can be connected to touch array 141 to drive touch array 141 based on (e.g., using) drive signals.

[0079] Display driver 172 may be electrically connected to display panel 142 to drive pixels PX. For example, display driver 172 may include a data driver connected to data line DL, a scan driver connected to drive line SL, and a timing controller that controls the data driver and the scan driver. In another example, display driver 172 may include a data driver and a timing controller, and the scan driver may be located in the non-display area NDA of display panel 142.

[0080] The display driver 172 can display images using display frame cycles as units. The touch driver 171 can sense touch using sensing frame cycles as units. The sensing frame cycles and display frame cycles can be synchronized or desynchronized with each other.

The driving electrodes TX may include first driving electrodes TX1 to q-th driving electrodes TXq (where q is a positive integer greater than 1). The sensing electrodes RX may include first sensing electrodes RX1 to p-th sensing electrodes RXp (where p is a positive integer greater than 1).

[0083] The first driving electrodes TX1 to the qth driving electrodes TXq can be connected to the first driving lines TXL1 to the qth driving lines TXLq, respectively. The first sensing electrodes RX1 to the pth sensing electrodes RXp can be connected to the first sensing lines RXL1 to the pth sensing lines RXLp, respectively.

[0084] Each of the first driving electrodes TX1 to the qth driving electrodes TXq may include a first cell CL1 arranged on the first direction DR1 and electrically connected to each other, and each of the first sensing electrodes RX1 to the pth sensing electrodes RXp may include a second cell CL2 arranged on the second direction DR2 and electrically connected to each other. Figure 4 The diagram shows that each of the first cell CL1 and the second cell CL2 has a rhomboid shape. However, embodiments of this disclosure are not limited to this. For example, each of the first cell CL1 and the second cell CL2 may have at least one of various suitable shapes, such as a circular shape, other quadrilateral shapes, and grid shapes. Furthermore, each of the first cell CL1 and the second cell CL2 may be formed as a single layer or multiple layers. In this way, the shape and arrangement of the first driving electrodes TX1 to the qth driving electrodes TXq and the first sensing electrodes RX1 to the pth sensing electrodes RXp can be modified differently in a suitable manner.

[0085] In some embodiments, the first cell CL1 and the second cell CL2 may include at least one of a variety of suitable conductive materials, such as metallic materials and transparent conductive materials, thereby being conductive. For example, each of the first cell CL1 and the second cell CL2 may include at least one of a variety of suitable metallic materials, such as gold (Au), silver (Ag), aluminum (Al), molybdenum (Mo), chromium (Cr), titanium (Ti), nickel (Ni), neodymium (Nd), copper (Cu), and platinum (Pt), or an alloy thereof.

[0086] Touch array 141 may further include input pads IPD connected to the first drive lines TXL1 to the qth drive lines TXLq. Touch driver 171 can be connected to the first drive lines TXL1 to the qth drive lines TXLq via the input pads IPD.

[0087] The touch array 141 may further include an output pad OPD connected to the first sensing lines RXL1 to the p-th sensing lines RXLp. The touch driver 171 may be connected to the first sensing lines RXL1 to the p-th sensing lines RXLp via the output pad OPD.

[0088] The touch array 141 may include a first touch electrode and a second touch electrode that form mutual capacitance with the first touch electrode. The first touch electrode may be configured as a first driving electrode TX1, a second driving electrode TX2, a third driving electrode TX3, ..., a (q-1)th driving electrode TX(q-1), and a qth driving electrode TXq. The second touch electrode may be configured as a first sensing electrode RX1, a second sensing electrode RX2, ..., a (p-2)th sensing electrode RX(p-2), a (p-1)th sensing electrode RX(p-1), and a pth sensing electrode RXp. The first driving electrodes TX1 to the qth driving electrodes TXq may extend in a first direction DR1 and be arranged to be spaced apart from each other in a second direction DR2. The first sensing electrodes RX1 to the pth sensing electrodes RXp may extend in the second direction DR2 and be arranged to be spaced apart from each other in the first direction DR1. The first sensing electrodes RX1 to the pth sensing electrodes RXp may intersect with the first driving electrodes TX1 to the qth driving electrodes TXq while being electrically separated from them to form mutual capacitance.

[0089] When a touch is provided to the touch array 141, one or more of the mutual capacitances may change. For example, a touch may include at least one of a variety of suitable types of inputs, such as physical contact and hovering, that cause a change in mutual capacitance. The touch driver 171 can recognize a touch by sensing the change in mutual capacitance.

[0090] The touch driver 171 can be connected to the first driving electrode TX1 to the qth driving electrode TXq via the first driving line TXL1, the second driving line TXL2, the third driving line TXL3, ..., the (q-1)th driving line TXL(q-1), and the qth driving line TXLq. The touch driver 171 can be connected to the first sensing electrode RX1 to the pth sensing electrode RXp via the first sensing line RXL1, the second sensing line RXL2, ..., the (p-2)th sensing line RXL(p-2), the (p-1)th sensing line RXL(p-1), and the pth sensing line RXLp.

[0091] The touch driver 171 can sense the sensing signals from the first sensing electrodes RX1 to RXp via the first sensing lines RXL1 to RXLp, and simultaneously apply driving signals to the first driving electrodes TX1 to TXq via the first driving lines TXL1 to TXLq. The touch driver 171 can change the mutual capacitance based on the sensing signals. Furthermore, the touch driver 171 can recognize touches by sensing changes in mutual capacitance.

[0092] Figure 5 This illustrates some embodiments according to the present disclosure. Figure 3Block diagram of the accessories, display driver, and display panel shown.

[0093] refer to Figure 3 and Figure 5 The display driver 172 may include a timing controller 172a, a data driver 172b, and a scan driver 172c.

[0094] The display driver 172 can receive external signals from the accessory 200. The display driver 172 can receive first image data DATA1 as an external signal. In some embodiments, the accessory 200 may include an application processor, a central processing unit (CPU), etc., that controls the display driver 172. In some embodiments, the accessory 200 may include a graphics processing unit (GPU) that controls the display driver 172. Furthermore, the accessory 200 may include at least one of various suitable means for providing the first image data DATA1 to the display driver 172.

[0095] The timing controller 172a can generate control signals for controlling the data driver 172b and the scan driver 172c based on (e.g., using) received external signals. For example, the control signals may include a scan driver control signal SCS for controlling the scan driver 172c and a data driver control signal DCS for controlling the data driver 172b. The external signals may include a vertical synchronization signal Vsync. For example, the vertical synchronization signal Vsync is a signal used to synchronize image data and may be a signal that uses one frame as a period input, serving as a signal for distinguishing frames. However, embodiments of this disclosure are not limited thereto. For example, the vertical synchronization signal Vsync may be generated internally in the timing controller 172a. For example, the timing controller 172a may include logic circuitry for generating the vertical synchronization signal Vsync.

[0096] The timing controller 172a can provide a scan driver control signal SCS to the scan driver 172c and a data driver control signal DCS to the data driver 172b. Furthermore, the timing controller 172a can convert externally input first image data DATA1 into second image data DATA2 conforming to the specifications of the data driver 172b, and provide the second image data DATA2 to the data driver 172b.

[0097] According to some embodiments, the display panel 142 may include pixels PX, and data lines DL and drive lines SL connected to the pixels PX. The data lines DL may include first data lines DL1 to nth data lines DLn (where n is a positive integer of 1 or greater). The drive lines SL may include first drive lines SL1 to mth drive lines SLm (where m is a positive integer of 1 or greater).

[0098] Data driver 172b can receive data driver control signal DCS and second image data DATA2 from timing controller 172a to generate a data signal. Furthermore, data driver 172b can provide the generated data signal to first data lines DL1 through nth data lines DLn. To connect data driver 172b to the first data lines DL1 through nth data lines DLn, data driver 172b can be directly mounted on a substrate on which pixels PX are formed, or connected to the substrate via a separate component (such as a flexible circuit board).

[0099] The scan driver 172c can provide drive signals to the first drive line SL1 through the m-th drive line SLm in response to the scan driver control signal SCS. For example, the scan driver 172c can sequentially provide drive signals to the first drive line SL1 through the m-th drive line SLm. To connect the scan driver 172c to the first drive line SL1 through the m-th drive line SLm, the scan driver 172c can be directly mounted on a substrate on which the pixel PX is formed, or connected to the substrate via a separate component (such as a flexible circuit board).

[0100] For example, when a drive signal is provided to a specific drive line, data signals transmitted from the first data line DL1 to the nth data line DLn can be provided to some pixels PX connected to the specific drive line. These pixels PX can then emit light with a brightness corresponding to the data signal.

[0101] Despite Figure 5 The timing controller 172a, data driver 172b, and scan driver 172c are shown separately, but at least some of these components can be integrated if needed.

[0102] Electrodes that provide voltage and / or signals to drive the display panel 142 can be called panel electrodes. Panel electrodes may correspond to data lines DL, drive lines SL, a first power supply ELVDD, a second power supply ELVSS, etc. A driving voltage can be provided to the panel electrodes. For example, each pixel PX can generate light corresponding to a data signal through current flowing from the first power supply ELVDD through the light-emitting element to the second power supply ELVSS. The first power supply ELVDD can be a high-potential voltage, and the second power supply ELVSS can be a low-potential voltage.

[0103] Figure 6 This illustrates some embodiments according to the present disclosure. Figure 1 A schematic diagram of the display device's board, adhesive layer, and printed circuit board as viewed in a first direction.

[0104] refer to Figure 1 and Figure 6The display device DD may include a board 150, an adhesive layer 160, and a printed circuit board 170. The adhesive layer 160 may include a first adhesive layer 161 and a second adhesive layer 162.

[0105] The first adhesive layer 161 may include a first tape 300 (e.g., see...). Figure 7 The second adhesive layer 162 may include a second tape 400 (e.g., see...). Figure 8 (See below for reference) Figure 7 and Figure 8 The first tape 300 constituting the first adhesive layer 161 and the second tape 400 constituting the second adhesive layer 162 are described.

[0106] The first adhesive layer 161 may be adhesive only on one surface. Therefore, the first adhesive layer 161 may be attached only to the printed circuit board 170.

[0107] On the other hand, the second adhesive layer 162 can be adhesive to both one surface and the other surface facing said one surface. Therefore, the second adhesive layer 162 can be attached to both the board 150 and the printed circuit board 170. Thus, the board 150 and the printed circuit board 170 can be attached to each other through the second adhesive layer 162.

[0108] The first adhesive layer 161 may include polyethylene terephthalate (PET). The first adhesive layer 161 may absorb pressure applied toward the first adhesive layer 161.

[0109] In the fastening process of display connector 180 and accessory connector 220, the pressure area PR can be the area to which unexpected pressure is applied.

[0110] In the pressure-bearing region PR of the display module 100 according to an embodiment of the present disclosure, a first adhesive layer 161 and a second adhesive layer 162 may be simultaneously mixed and disposed. The first adhesive layer 161 disposed in the pressure-bearing region PR can absorb the pressure applied to the pressure-bearing region PR. Therefore, when the pressure transmitted to the protective layer 110 is reduced (e.g., minimized), damage to the protective layer 110 can be prevented or substantially reduced.

[0111] Please refer to later Figure 9 The arrangement of the first adhesive layer 161 and the second adhesive layer 162 in the pressure zone PR is described in more detail.

[0112] Figure 7 This illustrates the configuration of some embodiments according to this disclosure. Figure 6 A schematic diagram of the first tape of the first adhesive layer shown.

[0113] refer to Figure 6 and Figure 7 The first adhesive layer 161 may include a first tape 300. The first tape 300 may include a first conductive adhesive 310 and a first material layer 320.

[0114] The first conductive adhesive 310 may overlap with the first material layer 320.

[0115] The first conductive adhesive 310 may include an epoxy resin. Furthermore, the first upper surface US1 of the first tape 300 may be adhesive. On the other hand, the first lower surface LS1 of the first tape 300 may not be adhesive. In other words, the first tape 300 may be a single-sided tape.

[0116] The first material layer 320 may include polyethylene terephthalate (PET). The first material layer 320 can absorb pressure applied toward it. Because the first adhesive layer 161 includes the first material layer 320, the first adhesive layer 161 can absorb pressure applied toward it. With the second material layer 420 (e.g., see...), Figure 8 Compared to the first material layer 320, it has excellent durability in resisting pressure.

[0117] In some embodiments, the first tape 300 may be white.

[0118] Figure 8 This illustrates the configuration of some embodiments according to this disclosure. Figure 6 A schematic diagram of the second tape of the second adhesive layer shown.

[0119] refer to Figure 6 and Figure 8 The second adhesive layer 162 may include a second tape 400. The second adhesive layer 162 may include a second conductive adhesive 410, a second material layer 420, and a third conductive adhesive 430.

[0120] The second material layer 420 may be disposed between the second conductive adhesive 410 and the third conductive adhesive 430.

[0121] The second conductive adhesive 410 and the third conductive adhesive 430 may comprise epoxy resin. Furthermore, the second upper surface US2 and the second lower surface LS2 of the second tape 400 may be adhesive. In other words, the second tape 400 may be a double-sided tape with adhesiveness on both sides. Because the second adhesive layer 162 comprises the second conductive adhesive 410 and the third conductive adhesive 430, the second adhesive layer 162 can be attached to the board 150 and the printed circuit board 170.

[0122] The second material layer 420 may include a non-woven fabric. This is related to the first material layer 320 (see, for example, [link to previous section]). Figure 7 In contrast, the second material layer 420 may not have excellent durability against pressure.

[0123] In some embodiments, the second tape 400 may be black.

[0124] Figure 9 This illustrates some embodiments according to the present disclosure. Figure 1 A schematic diagram of the adhesive layer, printed circuit board, and display connector of the display device shown, viewed from a third-party perspective.

[0125] refer to Figure 1 and Figure 9 The display device DD may include an adhesive layer 160, a printed circuit board 170, and a display connector 180.

[0126] After the fastening process of display connector 180 and accessory connector 220 is performed, display connector 180 can be as follows: Figure 2 The curve shown is designed to overlap with the compressed region PR. Figure 9 , Figure 11 and Figure 12 The image shows a display device DD prior to the fastening process of the display connector 180 and accessory connector 220.

[0127] The adhesive layer 160 may include a first adhesive layer 161 and a second adhesive layer 162.

[0128] like Figure 9 As shown, the first adhesive layer 161 and the second adhesive layer 162 can be simultaneously mixed in the pressure region PR. For example, in the pressure region PR, the first adhesive layer 161 and the second adhesive layer 162 can overlap each other in the first direction DR1 while being spaced apart from each other by a predetermined distance.

[0129] In the pressure-bearing region PR, the width of the first adhesive layer 161 in the first direction DR1 may be a first length D1. In the pressure-bearing region PR, the width of the second adhesive layer 162 in the first direction DR1 may be a second length D2. In some embodiments, the first length D1 may be greater than the second length D2.

[0130] In areas other than the pressure zone PR, the first adhesive layer 161 and the second adhesive layer 162 may not be mixed simultaneously. For example, the second adhesive layer 162 may be located in an area positioned in the second direction DR2 from the pressure zone PR. For example, the first adhesive layer 161 may be located in an area positioned in the opposite direction to the pressure zone PR in the second direction DR2.

[0131] In the pressure-bearing region PR of the display device DD according to an embodiment of the present disclosure, a first adhesive layer 161 and a second adhesive layer 162 may be simultaneously mixed and disposed. The first adhesive layer 161 disposed in the pressure-bearing region PR can absorb the pressure applied to the pressure-bearing region PR. Therefore, when the pressure transmitted to the protective layer 110 is reduced (e.g., minimized), damage to the protective layer 110 can be prevented or substantially reduced.

[0132] Figure 10 This illustrates some embodiments according to the present disclosure. Figure 1 A schematic diagram of the display device's board, adhesive layer, and printed circuit board as viewed in a first direction.

[0133] refer to Figure 1 and Figure 10 The display device DD may include a board 150, an adhesive layer 160, and a printed circuit board 170. The adhesive layer 160 may include a first adhesive layer 161 and a second adhesive layer 162. The second adhesive layer 162 may include a first sub-adhesive layer 162a and a second sub-adhesive layer 162b. The second sub-adhesive layer 162b may be spaced apart from the first sub-adhesive layer 162a. For example, the second sub-adhesive layer 162b may be spaced apart from the first sub-adhesive layer 162a in a second direction DR2.

[0134] The first adhesive layer 161 may include a first tape 300 (e.g., see...). Figure 7 Each of the first sub-adhesive layer 162a and the second sub-adhesive layer 162b may include a second tape 400 (e.g., see...). Figure 8 ).

[0135] The first adhesive layer 161 may be adhesive only on one surface. Therefore, the first adhesive layer 161 may be attached only to the printed circuit board 170.

[0136] On the other hand, each of the first sub-adhesive layer 162a and the second sub-adhesive layer 162b can be adhesive to both one surface and the other surface facing said one surface. Therefore, each of the first sub-adhesive layer 162a and the second sub-adhesive layer 162b can be attached to both the board 150 and the printed circuit board 170. Thus, the board 150 and the printed circuit board 170 can be attached to each other via each of the first sub-adhesive layer 162a and the second sub-adhesive layer 162b.

[0137] The first adhesive layer 161 may include polyethylene terephthalate (PET). The first adhesive layer 161 may absorb pressure applied toward the first adhesive layer 161.

[0138] In the fastening process of display connector 180 and accessory connector 220, the pressure area PR can be the area to which unexpected pressure is applied.

[0139] In the pressure-bearing region PR of the display module 100 according to an embodiment of the present disclosure, only the first adhesive layer 161 may be provided. The first adhesive layer 161 provided in the pressure-bearing region PR can absorb the pressure applied to the pressure-bearing region PR. Therefore, when the pressure transmitted to the protective layer 110 is reduced (e.g., minimized), damage to the protective layer 110 can be prevented or substantially reduced.

[0140] Furthermore, in the display module 100 according to an embodiment of the present disclosure, the first sub-adhesive layer 162a and the first adhesive layer 161 can be simultaneously mixed in a region other than the pressure region PR (e.g., the first region R1). Therefore, the adhesion between the board 150 and the printed circuit board 170 can be enhanced.

[0141] Please refer to later Figure 11 The arrangement of the first adhesive layer 161, the first sub-adhesive layer 162a, and the second sub-adhesive layer 162b will be described in more detail.

[0142] Figure 11 This illustrates some embodiments according to the present disclosure. Figure 1 A schematic diagram of the adhesive layer, printed circuit board, and display connector of the display device shown, viewed from a third-party perspective.

[0143] refer to Figure 1 , Figure 10 and Figure 11 The display device DD may include an adhesive layer 160, a printed circuit board 170, and a display connector 180.

[0144] Adhesive layer 160 may include a first adhesive layer 161 and a second adhesive layer 162. The second adhesive layer 162 may include a first sub-adhesive layer 162a and a second sub-adhesive layer 162b.

[0145] like Figure 11 As shown, only the first adhesive layer 161 can be provided in the pressure zone PR. The first adhesive layer 161 provided in the pressure zone PR can absorb the pressure applied to the pressure zone PR. Therefore, when the pressure transmitted to the protective layer 110 is reduced (e.g., minimized), damage to the protective layer 110 can be prevented or substantially reduced.

[0146] On the other hand, the first region R1 can be positioned from the pressure region PR in the opposite direction to the second direction DR2. In the first region R1, the first adhesive layer 161 and the first sub-adhesive layer 162a can be simultaneously mixed and disposed. For example, in the first region R1, a portion of the first adhesive layer 161 and the first sub-adhesive layer 162a can overlap each other in the first direction DR1 and the second direction DR2. For example, in the first region R1, the first adhesive layer 161 can surround three surfaces of the first sub-adhesive layer 162a. The simultaneous mixing and disposal of the first sub-adhesive layer 162a and the first adhesive layer 161 in the first region R1 can enhance the adhesion between the board 150 and the printed circuit board 170.

[0147] In regions other than the first region R1, the first adhesive layer 161 and the second adhesive layer 162 may not be mixed simultaneously. A second sub-adhesive layer 162b may be provided in a region positioned in the second direction DR2 starting from the pressure region PR. For example, the first adhesive layer 161 may be provided in the pressure region PR. For example, the first adhesive layer 161 may be provided in a region other than the first region R1 in a region positioned in the opposite direction of the second direction DR2 starting from the pressure region PR.

[0148] Figure 12 This illustrates some embodiments according to the present disclosure. Figure 1 A schematic diagram of the adhesive layer, printed circuit board, and display connector of the display device shown, viewed from a third-party perspective.

[0149] refer to Figure 1 and Figure 12 The display device DD may include an adhesive layer 160, a printed circuit board 170, and a display connector 180.

[0150] Adhesive layer 160 may include a first adhesive layer 161 and a second adhesive layer 162. The second adhesive layer 162 may include a first sub-adhesive layer 162a, a second sub-adhesive layer 162b, and a third sub-adhesive layer 162c. The third sub-adhesive layer 162c may be spaced apart from the first sub-adhesive layer 162a and the second adhesive layer 162b.

[0151] like Figure 12 As shown, only the first adhesive layer 161 may be provided in the pressure zone PR. The first adhesive layer 161 provided in the pressure zone PR can absorb the pressure applied to the pressure zone PR. Therefore, when the pressure transmitted to the protective layer 110 is reduced (e.g., minimized), damage to the protective layer 110 can be prevented or substantially reduced.

[0152] On the other hand, the first region R1 can be positioned from the pressure region PR in the opposite direction to the second direction DR2. In the first region R1, the first adhesive layer 161 and the first sub-adhesive layer 162a can be simultaneously mixed and disposed. For example, in the first region R1, a portion of the first adhesive layer 161 and the first sub-adhesive layer 162a can overlap each other in the first direction DR1 and the second direction DR2. For example, in the first region R1, the first adhesive layer 161 can surround three surfaces of the first sub-adhesive layer 162a. The simultaneous mixing and disposal of the first sub-adhesive layer 162a and the first adhesive layer 161 in the first region R1 can enhance the adhesion between the board 150 and the printed circuit board 170.

[0153] Unlike the first region R1, the second region R2 can be positioned in the opposite direction to the second direction DR2, starting from the pressure region PR. In the second region R2, the first adhesive layer 161 and the third sub-adhesive layer 162c can be simultaneously mixed and disposed. For example, in the second region R2, a portion of the first adhesive layer 161 and the third sub-adhesive layer 162c can overlap each other in the first direction DR1 and the second direction DR2. For example, in the second region R2, the first adhesive layer 161 can surround three surfaces of the third sub-adhesive layer 162c.

[0154] Reference Figure 10 and Figure 11 Compared to other embodiments of the display device described in this disclosure, reference is made to... Figure 12 The display device described in other embodiments of the present disclosure may further include a second region R2. In the second region R2, a third sub-adhesive layer 162c and a first adhesive layer 161 are simultaneously mixed and disposed, such that the adhesion between the board 150 and the printed circuit board 170 can be further enhanced compared to the display device according to some other embodiments of the present disclosure.

[0155] In regions other than the first region R1 and the second region R2, the first adhesive layer 161 and the second adhesive layer 162 may not be mixed simultaneously. A second sub-adhesive layer 162b may be provided in a region positioned in the second direction DR2 starting from the pressure region PR. For example, the first adhesive layer 161 may be provided in the pressure region PR. For example, the first adhesive layer 161 may be provided in a region positioned in the opposite direction of the second direction DR2 starting from the pressure region PR, excluding the first region R1 and the second region R2.

[0156] In the display module and display device including the display module according to the present disclosure, the durability of the display module is enhanced, thereby preventing the display module from being damaged or squeezed due to pressure, or significantly reducing such damage.
