Description

[Technical field]

[0001] The present specification relates to a display device, and more particularly to a display device capable of preventing penetration of external moisture. [Background technology]

[0002] 2. Description of the Related Art Recently, display devices capable of displaying various information and interacting with a user viewing the information are required to have various sizes, shapes and functions.

[0003] Such display devices include liquid crystal display devices (LCDs), electrophoretic display devices (FPDs), and organic light emitting diode display devices (OLEDs).

[0004] Organic light emitting display devices are self-emitting displays that do not require a separate light source, unlike liquid crystal displays (LCDs), and can be manufactured in a lightweight and thin form. In addition, organic light emitting diode displays are advantageous in terms of power consumption due to their low voltage operation, and are also excellent in color realization, response speed, viewing angle, and contrast ratio (CR), and are therefore being researched as next-generation displays.

[0005] An OLED display uses a number of thin film transistors (TFTs) to control the current flowing through the OLED to display images.

[0006] The display device is being developed with the addition of cameras, speakers, sensors, etc.

[0007] In particular, a hole-in-display structure in which a hole is formed in the display device in order to place a sensor such as a camera in the display device is applied.

[0008] Forming holes in the display device causes a problem that moisture from the outside penetrates into the display area inside the display panel. Summary of the Invention [Problem to be solved by the invention]

[0009] This specification allows for the formation of a through hole in an area for placing a camera within the display area of ​​the display device.

[0010] The through-holes may be formed by removing the substrate and a layer above the substrate.

[0011] A first region including a hole region, a first pattern portion, a first dam portion, and a second pattern portion can be disposed to form a through-hole in the display region.

[0012] The first pattern portion adjacent to the hole region of the first region may have a plurality of first patterns including a columnar lower pattern and a trapezoidal upper pattern disposed on the lower pattern to disconnect the light emitting layer.

[0013] The insulating layer disposed on the plurality of first patterns may not be filled in reverse taper regions formed between the plurality of first patterns, and an empty space (ES) may be formed.

[0014] A seam may be formed due to an empty space (ES) and the end of the trapezoidal upper pattern.

[0015] In the hole region formed by removing the substrate and the layer on the substrate, the side surface of the layer on the substrate can be exposed to the outside.

[0016] External moisture that has entered the organic insulating layer, which is made of organic material among the layers on the substrate exposed to the outside, can seep into the panel display area through a seam formed in the first pattern part adjacent to the hole area, resulting in a problem of degraded quality of the display device.

[0017] Therefore, this specification invents a display device that can prevent the penetration of external moisture by improving the laminated structure of an insulating layer and a protective layer on a first pattern portion of a first region formed to place a Hole In Display camera.

[0018] The problem to be solved by the embodiments of the present specification is to provide a display device and a manufacturing method thereof that can prevent penetration of external moisture by disposing a protective layer between insulating layers on a first pattern portion of a first region formed for arranging a camera.

[0019] The problems to be solved by the embodiments of the present specification are not limited to those mentioned above, and other problems not mentioned will be clearly understood by those skilled in the art from the following description. [Means for solving the problem]

[0020] A display device according to an embodiment of the present specification includes a substrate including a display region and a non-display region, and a first region disposed in the display region, and includes a hole region, a first pattern portion, a first dam portion, and a second pattern portion in the first region, a sealing layer on at least a portion of the first region, a first insulating layer and a second insulating layer, and a plurality of first patterns disposed in the first pattern portion, wherein the first insulating layer and the second insulating layer are spaced apart from each other between the plurality of first patterns, and the first insulating layer and the second insulating layer are in contact with each other on at least a portion of the upper surfaces of the plurality of first patterns.

[0021] Further details of the embodiments are included in the detailed description and the drawings.

[0022] The display device according to the embodiments of the present specification is provided with an insulating layer and a protective layer structure on a first pattern portion of a first region formed for arranging a camera within a display area, thereby making it possible to provide a display device and a manufacturing method thereof that can effectively prevent external moisture from penetrating the panel and improve degradation of panel quality due to moisture permeation.

[0023] The effects of the present specification are not limited to those mentioned above, and other effects not mentioned will be clearly understood by those skilled in the art from the following description.

However, the present specification is not limited to the embodiments disclosed below, but may be embodied in various different forms, and the embodiments are provided to complete the disclosure of the present specification and to fully inform those skilled in the art of the invention, and the present specification is defined only by the scope of the claims.

[0027] The shapes, sizes, ratios, angles, numbers, etc. disclosed in the drawings for explaining the embodiments of this specification are illustrative only, and this specification is not limited to the matters shown in the drawings. The same reference symbols indicate the same components throughout the specification. In addition, in the description of this specification, if it is determined that a specific description of related known technology may unnecessarily obscure the gist of this specification, the detailed description will be omitted. When the terms "include", "have", "consist of", etc. are used in this specification, other parts may be added unless "only" is used. When a component is expressed in the singular, it includes a plural unless otherwise explicitly stated.

[0028] In interpreting elements, the error range is interpreted as being included even if there is no separate explicit description of the error range.

[0029] In describing a positional relationship, for example, when the positional relationship between two parts is described using terms such as "above," "upper," "lower," "beside," etc., one or more other parts may be located between the two parts, unless, for example, "immediately" or "directly" is used.

[0030] In the case of an explanation of a temporal relationship, when the temporal sequence is explained using "after," "following," "next," "before," etc., it can also include cases where the sequence is not consecutive, since "immediately" or "directly" is not used.

[0031] Although the terms "first", "second", etc. are used to describe various components, these components are not limited by these terms.

[0032] In describing components in this specification, terms such as first, second, A, B, (a), (b), etc. may be used. Such terms are merely intended to distinguish the components from other components, and do not limit the nature, order, sequence, or number of the components. When a component is described as being "coupled," "connected," or "connected" to another component, it should be understood that the component may be directly connected or connected to the other component, but unless otherwise expressly stated, other components may be "intervened" between each component that may be indirectly connected or connected.

[0033] "At least one" should be understood to include all combinations of one or more of the associated components. For example, "at least one of a first, second, and third component" means not only the first, second, or third component, but also all combinations of two or more of the first, second, and third components.

[0034] In this specification, the term "apparatus" may include display devices such as liquid crystal modules (LCMs) and organic light emitting display modules (OLED modules) that include a display panel and a driver for driving the display panel, and may also include set electronic apparatuses or set devices or set apparatuses such as notebook computers, televisions, computer monitors, automotive apparatuses, and mobile electronic apparatuses such as smartphones or electronic pads that are complete or final products that include LCMs or OLED modules.

[0035] Therefore, the device in this specification can include a display device itself such as an LCM, an OLED module, etc., and a set device which is an application product or a final consumer device including an LCM, an OLED module, etc.

[0036] In some embodiments, an LCM or OLED module including a display panel and a driver may be referred to as a "display device," and a completed electronic device including the LCM or OLED module may be referred to as a "set device." For example, the display device may include a liquid crystal (LCD) or organic light emitting diode (OLED) display panel and a source PCB serving as a controller for driving the display panel. The set device may further include a set PCB serving as a set controller electrically connected to the source PCB and driving the entire set device.

[0037] The display panel used in the embodiments of the present specification may be any type of display panel such as a liquid crystal display panel, an organic light emitting diode (OLED) display panel, and an electroluminescent display panel, and the embodiments are not limited thereto. For example, the display panel may be a display panel that can generate sound by vibrating with a vibration device according to the embodiments of the present specification. The display panel applied to the display device according to the embodiments of the present specification is not limited to the shape or size of the display panel.

[0038] The features of the various embodiments of this specification may be partially or fully combined or combined with each other, and various technical interlocking and driving mechanisms may be possible, and each embodiment may be implemented independently of each other or may be implemented together in a related relationship.

[0039] The present invention will be described in detail with reference to the accompanying drawings and examples as follows: The scales of the components illustrated in the drawings are different from the actual scales for the convenience of explanation, and therefore the present invention is not limited to the scales illustrated in the drawings.

[0040] Various embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings.

[0041] FIG. 1 is a plan view that illustrates a schematic example of a display device according to an embodiment of the present specification.

[0042] The display device 10 may include a plurality of regions. For example, the display device 10 may include one or more display areas AA in which an image is displayed, and a pixel PXL array is formed inside the display area AA. One or more non-display areas NA in which no image is displayed may include a driving circuit section and a dam section, and may be provided on one side of the display area AA. For example, the non-display area NA may be adjacent to one or more sides of the display area AA.

[0043] 1, the non-display area NA may be located outside and surround the substantially rectangular display area AA. However, it should be understood that the shape of the display area AA and the arrangement of the non-display area NA adjacent to the display area AA are not specifically limited to the exemplary display device 10 illustrated in FIG. The display area AA and the non-display area NA may be any shape of the display device 10. Examples of such shapes may include pentagons, hexagons, circles, ellipses, etc., and examples herein are not limited thereto.

[0044] Each pixel PXL in the display area AA includes a sub-pixel, which can display colors such as red (R), green (G), blue (B), and white (W). Each pixel PXL and sub-pixel may also be associated with a pixel circuit including one or more transistors (TFT: Thin Film Transistor) fabricated on a substrate of the display device 10. Each pixel circuit may be electrically coupled to gate lines and data lines for communication with one or more driving circuits, such as a gate driver GIP and a data driver D-IC located in the non-display area NA of the display device 10.

[0045] One or more driving circuits may be implemented with TFTs arranged in the non-display area NA as shown in Fig. 1. For example, the gate driver GIP may be implemented using a plurality of TFTs on the substrate of the display device 10. Non-limiting examples of circuits that may be implemented with the TFTs on the substrate may include an inverter circuit, a multiplexer, and an ESD (electro static discharge) circuit, and the embodiments of the present specification are not limited thereto.

[0046] Some of the driving circuits may be provided as an integrated circuit (IC) chip and mounted in the non-display area NA of the display device 10 using chip-on-glass (COG) or other similar methods, or some of the driving circuits may be mounted on another substrate and coupled to connection interfaces (pads / bumps, pins) disposed in the non-display area NA using a printed circuit such as a flexible printed circuit board (PCB), chip-on-film (COF), tape-carrier-package (TCP), or other suitable technology.

[0047] In the embodiments herein, at least two different types of TFTs are used in the TFT substrate for the display. The types of TFTs employed in the pixel circuit part and the driving circuit part may vary depending on the requirements of the display.

[0048] For example, the pixel circuit may be implemented with a TFT having an oxide active layer (oxide TFT), and the driving circuit may be implemented with a TFT having a low temperature polysilicon active layer (LTPS TFT) and a TFT having an oxide active layer. Unlike LTPS TFTs, oxide TFTs do not have the problem of threshold voltage Vth variation from the pixel-to-pixel. A uniform threshold voltage Vth may also be obtained in an array of pixel circuits for a display. The problem of uniformity of threshold voltage Vth among TFTs implementing the driving circuit will have less direct impact on pixel brightness uniformity.

[0049] The driving circuit (eg, GIP) incorporates a gate driving IC inside the display panel, thereby reducing the number of driving ICs and reducing costs, and providing a high-speed scan signal to the display area of ​​the display panel.

[0050] By using a driving circuit on a substrate realized with LTPS TFTs, signals and data can be provided to pixels at a higher clock than when all TFTs in a TFT panel are formed with oxide TFTs. Therefore, a display capable of high speed operation can be provided uniformly. For example, the advantages of oxide TFTs and LTPS TFTs can be combined with the design of a TFT panel, and oxide TFTs and LTPS TFTs can be selected and used according to their respective advantages.

[0051] The display area AA can include a first area PH, which includes a hole area H and a first pattern portion PT1, a first dam portion DM, a second pattern portion PT2, and a routing wiring area RK surrounding the hole area H in order to arrange a camera within the display area AA, and the configurations of these will be described in detail below.

[0052] 2 and 3 are three-dimensional diagrams that diagrammatically illustrate an example of a display device according to an embodiment of the present specification.

[0053] A display device according to an embodiment of the present specification may be applied to a foldable display device.

[0054] A foldable display device may include at least one display area AA.

[0055] A foldable display device may be arranged such that one display area of ​​the display device is folded along a folding line to be divided into a first display area AA1 and a second display area AA2, or may have multiple display areas inside and outside the display device. Pixels PXL are formed in the display areas.

[0056] Referring to FIG. 3, the foldable display device may further include a first display area AA1 and a second display area AA2 disposed inside the display device, and a third display area AA3 disposed outside the display device.

[0057] Referring to Figures 2 and 3, the first area PH for placing a camera within the display area AA may be arranged in one or more of the first display area AA1 arranged inside the display device, the second display area AA2, or the third display area AA3 arranged outside the display device.

[0058] FIG. 4 is an enlarged view that illustrates a schematic view of the first region PH of the display device 10 of this specification.

[0059] The first area PH includes a hole area H for arranging a camera within the display area AA, and a first pattern portion PT1, a first dam portion DM, a second pattern portion PT2, and a routing wiring area RK surrounding the hole area H.

[0060] FIG. 5 is a cross-sectional view that diagrammatically illustrates an example of a cross section taken along line AA' of FIG.

[0061] Referring to FIG. 5, a substrate 100 of a display device according to an embodiment of the present specification may include a first substrate, a second substrate, and an intermediate layer between the first substrate and the second substrate.

[0062] The first and second substrates may be made of at least one of polyimide, polyethersulfone, polyethylene terephthalate, and polycarbonate, and the embodiments of the present specification are not limited thereto. When the substrate is made of a plastic material, a manufacturing process of the display device may be performed in a state where a supporting substrate made of glass is disposed under the substrate, and the supporting substrate may be released after the manufacturing process of the display device is completed. In addition, after the supporting substrate is released, a back plate (or plate) for supporting the substrate may be disposed under the substrate. When the substrate is made of a plastic material, moisture may penetrate the substrate and the moisture may penetrate to the thin film transistor or the light emitting element layer, thereby degrading the performance of the display device. The display device according to the embodiments of the present specification may be composed of two substrates, a first substrate and a second substrate, made of a plastic material, in order to prevent the performance of the display device from degrading due to moisture penetration. In addition, by forming an intermediate layer, which is an inorganic film, between the first substrate and the second substrate, moisture may be prevented from penetrating the substrate, thereby improving the performance reliability of the product. The intermediate layer may be an inorganic film, for example, but not limited to, a single layer of silicon nitride (SiNx) or silicon oxide (SiOx) or multiple layers thereof.

[0063] The display device formed on the substrate 100 may include a plurality of regions. In this specification, the display device is configured with a display region AA and a non-display region NA, but is not limited thereto.

[0064] A buffer layer consisting of a single layer of silicon nitride (SiNx) or silicon oxide (SiOx) or multiple layers thereof may be disposed on one side of the display area AA and the non-display area NA on the substrate 100. The buffer layer may improve the adhesion between the substrate 100 and layers formed on the buffer layer, and may block various types of defect factors such as alkaline components that flow out from the substrate 10. The buffer layer may also delay the diffusion of moisture or oxygen that has penetrated into the substrate 100.

[0065] The buffer layer may be omitted depending on the type and material of the substrate, the structure and type of the thin film transistor, and so on.

[0066] Transistors in the display area AA and the non-display area NA may be formed on the substrate 100 and the buffer layer. The transistors in the display area AA may include a switching transistor SW Tr and a driving transistor DR Tr for driving the subpixel, and the transistors in the non-display area NA may include a first gate driving transistor GT1 and a second gate driving transistor GT2 for driving the gate driver GIP.

[0067] In the drive transistor DRTr, a light-shielding layer 200 may be disposed on a substrate 100 or a buffer layer.

[0068] The light-shielding layer 200 blocks light toward the first semiconductor layer 210 of the driving transistor DRTr, and is connected to the first drain electrode 230D to prevent a phenomenon in which parasitic carriers are accumulated in the first semiconductor layer 210, causing a sudden increase in drain current, and a change in threshold voltage due to this phenomenon.

[0074] The metal oxide semiconductor may have improved conductive properties through a doping process of injecting impurities, and may include a channel region in which a channel through which electrons and holes move is formed, and a source region and a drain region which are conductive regions on both sides of the channel region. A source electrode and a drain electrode may be connected to the source region and the drain region.

[0172] The width of the lower surface of the upper pattern PTb disposed on the lower pattern PTa is wider than the width of the upper surface of the lower pattern PTa.

[0173] The light emitting device layer 610 arranged on the upper and side surfaces of the upper pattern PTb may be disconnected by multiple patterns PT because the light emitting device layer 610 is not formed on the side surface of the lower pattern PTa due to the separation space between the lower surface of the upper pattern PTb and the side surface of the lower pattern PTa.

[0182] In an area between the patterns PT of the first pattern unit PT1, a passivation layer 60 may be disposed between the touch buffer layer 800 and the touch insulation layer 820, so that the touch buffer layer 800 and the touch insulation layer 820 may be spaced apart from each other.

[0185] Moisture input through the hole region H may permeate into the voids (ES) formed in the pattern PT of the first pattern portion PT1 through the third planarization layer 850 made of an organic material and move to the display area AA, thereby degrading the quality of the display panel.

[0186] The protective layer 60 may be disposed between the multiple patterns PT, and the touch buffer layer 800 and the touch insulating film 820 on the upper surfaces of the multiple patterns PT may be in contact with each other.

[0187] Even if the protective layer 60 is made of an organic material, it is not connected to the touch buffer layer 800 and the touch insulating layer 820 on the upper surfaces of the patterns PT, so that the protective layer 60 can prevent moisture from being transferred.

[0188] In addition, since the protective layer 60 is formed, the distance between the voids (ES) and seams and the third planarization layer 850 becomes large, so that moisture in the third planarization layer 850 is not transferred.

[0189] A first height H1 from the lower surface of the lower pattern PTa to the upper surface of the upper pattern PTb of the multiple patterns PT of the first pattern portion PT1 and a second height H2 from the lower surface of the lower pattern PTa to the upper surface of the protective layer 60 may be different from each other, and the second height H2 may be higher than the first height H1.
