Description

Technical Field

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

Background Art

[0002] Recent display devices that can display various information and interact with users who view the relevant information are required to have various sizes, various forms, and various functions.

[0003] Such display devices include a liquid crystal display device (LCD), an electrophoretic display device (FPD), and an organic light emitting diode display device (OLED).

[0004] The organic light emitting display device is a self-luminous display device. Different from a liquid crystal display device (LCD), it does not require a separate light source, so it can be manufactured in a lightweight and thin form. In addition, the organic light emitting diode display device is not only advantageous in terms of power consumption due to low voltage driving, but also excellent in terms of color rendering, response speed, viewing angle, and contrast ratio (CR), so it is being studied as a next-generation display.

[0005] The organic light emitting diode display device uses a number of thin film transistors (or "TFT") to control the current flowing through the organic light emitting diode to display an image.

[0006] Display devices are being developed with additional components such as cameras, speakers, and sensors.

[0007] In particular, in order to arrange a sensor such as a camera in the display device, a hole in display (Hole In Display) structure for forming a hole in the device is applied.

[0008] There is a problem that external moisture penetrates into the display area inside the display panel by forming holes in the display device.

Summary of the Invention

Problems to be Solved by the Invention

[0009] This specification can form a through hole in an area for arranging a camera within a display area of a display device.

[0010] The through hole can be formed by removing a substrate and layers on the substrate.

[0011] To form a through hole in the display area, a first area including a hole area, a first pattern part, a first dam part, and a second pattern part can be arranged.

[0012] A plurality of first patterns including a columnar lower pattern and a trapezoidal upper pattern on the lower pattern can be arranged in the first pattern part adjacent to the hole area of the first area to cut off the connection of the light-emitting layer.

[0013] An insulating layer arranged on the plurality of first patterns can form an empty space (ES) without being filled in an inverse taper region formed between the plurality of first patterns.

[0014] A seam can be formed by the empty space (ES) and the end of the trapezoidal upper pattern.

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

[0016] There was a problem that the quality of the display device deteriorated because external moisture flowing into the organic insulating layer formed of an organic substance among the layers on the substrate exposed to the outside penetrated into the panel display area through a seam formed in the first pattern part adjacent to the hole area.

[0017] Therefore, the present specification has invented 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 dispose a camera of a Hole In Display.

[0018] The problem to be solved according to an embodiment of the present specification is to provide a display device capable of preventing the penetration of external moisture by disposing a protective layer between insulating layers on a first pattern portion of a first region formed to dispose a camera, and a manufacturing method thereof.

[0019] The problem to be solved according to an embodiment of the present specification is not limited to the problems 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] The 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 part of the first region, a first insulating layer, a second insulating layer, and a plurality of first patterns disposed on the first pattern portion, the first insulating layer and the second insulating layer are separated from each other between the plurality of first patterns, and the first insulating layer and the second insulating layer may be in contact with each other at least on a part of the upper surface of the plurality of first patterns.

[0021] Specific matters of other embodiments are included in the detailed description and the drawings.

[0022] The display device according to an embodiment of the present specification includes an insulating layer and a protective layer structure on a first pattern portion of a first region formed to dispose a camera within a display region, thereby effectively preventing the penetration of external moisture of the panel, and can provide a display device capable of improving the quality degradation of the panel due to moisture permeability and a manufacturing method thereof.

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

[0024] As described above, since the content of the invention described in the problem to be solved, the means for solving the problem, and the effects does not specify the essential features of the claims, the scope of the claims is not limited by the matters described in the content of the invention.

However, this specification is not limited to the embodiments disclosed below and may be embodied in various different forms, provided that these embodiments make the disclosure of this specification complete and are provided to fully inform those having ordinary knowledge in the technical field to which this specification belongs of the scope of the invention, and this specification is only defined 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 exemplary, so this specification is not limited to the illustrated matters. The same reference signs throughout the specification indicate the same components. Also, in the description of this specification, when it is determined that a specific description of related known technologies may unnecessarily obscure the gist of this specification, the detailed description thereof will be omitted. When terms such as "including", "having", "consisting of", etc. mentioned in this specification are used, other parts may be added as long as "only" is not used. When a component is expressed in the singular, it includes the case of including a plurality unless otherwise explicitly stated.

[0028] In the interpretation of components, even if there is no separate explicit description of the error range, it is interpreted as including the error range.

[0029] In the case of an explanation of the positional relationship, for example, when the positional relationship between both parts is explained by "above", "on the upper part", "on the lower part", "sideways", etc., one or more other parts may be located between both parts as long as "immediately" or "directly" is not used.

[0030] In the case of an explanation of the time relationship, when the time sequence relationship is explained by "after", "subsequent to", "next", "before", etc., it can include the case where it is not continuous as long as "immediately" or "directly" is not used.

[0031] The first, second, etc. are used to describe various components, but these components are not limited by these terms. These terms are merely used to distinguish one component from another. Therefore, the first component mentioned below may be the second component within the technical idea of this specification.

[0032] In the description of the components of this specification, terms such as first, second, A, B, (a), (b), etc. can be used. Such terms are only for distinguishing the components from other components, and do not limit the essence, order, sequence, or number of the corresponding components. When a component is described as being "connected", "coupled", or "connected" to another component, the component can be directly connected or connected to the other component, but unless otherwise explicitly stated, it should be understood that other components may "intervene" between the components that can be indirectly connected or connected.

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

[0034] As used herein, "apparatus" can include display devices such as liquid crystal modules (Liquid Crystal Module; LCM) including a display panel and a driving unit for driving the display panel, and organic light emitting display modules (OLED Module). And it can also include set electronic devices or set devices such as notebook computers, televisions, computer monitors, vehicle or automotive apparatus, mobile electronic apparatuses such as smartphones or electronic pads, etc., which are complete products including LCM, OLED modules, etc.

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

[0036] And in some embodiments, an LCM or an OLED module composed of a display panel, a driving unit, etc. may be expressed as a "display device", and an electronic device as a finished product including an LCM or an OLED module may be distinguished and expressed as a "set device". For example, the display device can include a liquid crystal (LCD) or an organic light emitting (OLED) display panel and a source PCB which is a control unit for driving the display panel. The set device can further include a set PCB which is a set control unit electrically connected to the source PCB to drive the whole set device.

For example, the display panel can be a display panel capable of generating sound by vibrating by the vibration device according to the embodiments of this specification. The display panel applied to the display device according to the embodiments of this specification is not limited by the form and size of the display panel.

[0038] The respective features of the various embodiments of this specification can be partially or wholly combined or combined with each other, various linkages and drives are technically possible, and each embodiment may be implemented independently of each other or may be implemented together in a related relationship.

[0039] Hereinafter, by examining the embodiments of this specification through the attached drawings and embodiments, it is as follows. Since the scale of the components illustrated in the drawings has a scale different from the actual one for the convenience of explanation, it is not limited to the scale illustrated in the drawings.

[0040] Hereinafter, various embodiments of this specification will be described in detail with reference to the drawings.

[0041] FIG. 1 is a plan view schematically showing an example of a display device according to an embodiment of this specification.

[0042] The display device 10 can include a plurality of regions. For example, the display device 10 includes one or more display regions AA which are regions where an image is displayed, and a pixel PXL array is formed inside the display region AA. One or more non-display regions NA where an image is not displayed include a drive circuit portion and a dam portion, and may be provided on one side surface of the display region AA. For example, the non-display region NA may be adjacent to one or more side surfaces of the display region AA.

[0043] Referring to FIG. 1, the non-display region NA can be located outside surrounding the substantially rectangular display region AA. However, it should be understood that the shape of the display region AA and the arrangement of the non-display region NA adjacent to the display region AA are not specifically limited to the exemplary display device 10 illustrated in FIG. 1. The display region AA and the non-display region NA may be of any shape of the display device 10. Examples of such shapes can include a pentagon, a hexagon, a circle, an ellipse, etc., and the embodiments of this specification are not limited thereto.

[0044] Each pixel PXL of the display region AA includes sub-pixels, and the sub-pixels can display colors such as red (R), green (G), blue (B), white (W), etc. Also, each of the pixel PXL and the sub-pixels may be associated with a pixel circuit including one or more transistors (TFT: Thin Film Transistor) manufactured on the substrate of the display device 10. Each pixel circuit may be electrically connected to a gate line and a data line to communicate with one or more drive circuits, for example, a gate driver GIP and a data driver D-IC located in the non-display region NA of the display device 10.

[0045] One or more driving circuits may be implemented by TFTs configured within a non-display area NA as illustrated 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 by the TFTs on the substrate may include an inverter circuit, a multiplexer, and an ESD (electro static discharge) circuit, etc., and the embodiments of the present specification are not limited thereto.

[0046] Some driving circuits may be provided as IC (integrated circuit) chips and may be mounted within the non-display area NA of the display device 10 using COG (chip-on-glass) or other similar methods. Also, some driving circuits may be further mounted on other substrates and may be coupled to connection interfaces (pads / bumps, pins) arranged in the non-display area NA using printed circuits such as flexible PCBs (printed circuit boards), COF (chip-on-film), TCP (tape-carrier-package), or other suitable technologies.

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

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

[0049] A drive circuit (e.g., GIP) incorporates a gate drive IC inside the display panel, enabling cost reduction by reducing the number of drive ICs and providing a high-speed scan signal to the display area of the display panel.

[0050] Using a drive circuit on a substrate implemented with LTPS TFTs, signals and data can be provided to pixels at a higher clock than when all TFTs in the TFT panel are formed of oxide TFTs. Therefore, a display capable of high-speed operation can be provided without unevenness. For example, the advantages of oxide TFTs and LTPS TFTs can be combined with the design of the TFT panel, and oxide TFTs and LTPS TFTs can be selected and used according to each advantage.

[0051] The display area AA can include a first area PH. The first area PH includes a hole area H, a first pattern portion PT1 surrounding the hole area H, a first dam portion DM, a second pattern portion PT2, and a routing wiring area RK for arranging a camera inside the display area AA. These configurations will be described in detail later.

[0052] FIG. 2 and FIG. 3 are perspective views schematically illustrating an example of a display device according to an embodiment of the present specification.

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

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

[0055] A foldable display device can be arranged such that one display area of the display device is folded with respect to a folding line and divided into a first display area AA1 and a second display area AA2, or can have a number of display areas on the inner and outer sides of the display device. Pixels PXL are formed in the display area.

[0056] Referring to FIG. 3, the foldable display device can 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 FIGS. 2 and 3, the first area PH for disposing a camera within the display area AA can be disposed in one or more of the first display area AA1 and the second display area AA2 disposed inside the display device, or the third display area AA3 disposed outside the display device.

[0058] FIG. 4 is an enlarged view schematically illustrating the first area PH of the display device 10 of the present specification.

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

[0060] FIG. 5 is a cross-sectional view schematically illustrating an example of the cross-section taken along the line A-A' of FIG. 1.

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

[0062] The first substrate and the second substrate can be formed 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, the manufacturing process of the display device proceeds with a support substrate made of glass disposed under the substrate, and the support substrate can be released after the manufacturing process of the display device is completed. Further, after the support substrate is released, a back plate (or plate) for supporting the substrate can be disposed under the substrate. When the substrate is made of a plastic material, moisture can penetrate the substrate and cause moisture permeation up 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 can be composed of two substrates, namely, the first substrate and the second substrate made of a plastic material, in order to prevent the performance of the display device from degrading due to moisture permeation. Then, by forming an intermediate layer, which is an inorganic film, between the first substrate and the second substrate, it is possible to block moisture from penetrating the substrate and improve the performance reliability of the product. The intermediate layer can be made of an inorganic film. For example, the intermediate layer can be composed of a single layer of silicon nitride (SiNx) or silicon oxide (SiOx) or a multilayer thereof, but is not limited thereto.

[0063] The display device formed on the substrate 100 can include a plurality of regions. Although the present specification describes the display region AA and the non-display region NA, it is not limited thereto.

[0064] A buffer layer composed of a single layer or multiple layers of silicon nitride (SiNx) or silicon oxide (SiOx) can be disposed on one surface of the display area AA and the non-display area NA on the substrate 100. The buffer layer can improve the adhesion between the layer formed on the buffer layer and the substrate 100, and can perform functions such as blocking various types of defect factors such as alkaline components flowing out from the substrate 10. In addition, the buffer layer can delay the diffusion of moisture or oxygen that has penetrated into the substrate 100.

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

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

[0067] For the driving transistor DR Tr, a light-shielding layer 200 may be disposed on the substrate 100 or the buffer layer.

[0069] The light-shielding layer 200 can be formed of a single layer or multiple layers having at least one of titanium (Ti), molybdenum (Mo), copper (Cu), aluminum (Al), silver (Ag), chromium (Cr), gold (Au), neodymium (Nd), and nickel (Ni), and the embodiments of this specification are not limited thereto.

[0074] The conductivity of the metal oxide semiconductor can be improved by a doping process of injecting impurities, and can include a channel region where a channel for electrons or holes to move is formed and source and drain regions that are regions made conductive on both sides of the channel region. Source electrodes and drain electrodes can be connected to the source region and the drain region.

However, the material of the insulating layer and the number of layers of the plurality of patterns PT are not limited to this.

[0171] The plurality of patterns PT can prevent moisture from penetrating into the display area AA through the light-emitting element layer 610 that is vulnerable to moisture penetration.

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

[0173] The light-emitting element layer 610 disposed on the upper surface and the side surface of the upper pattern PTb can be disconnected by the plurality of patterns PT because the light-emitting element layer 610 is not formed on the side surface portion 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.

[0174] In addition, the first sealing layer 710 disposed in the routing wiring region RK, the first pattern portion PT1, the first dam portion DM, and the second pattern portion PT2 of the first region PH can be formed on the upper surface and the side surface of the upper pattern PTb and a part of the lower surface of the upper pattern PTb, and since it is not formed on a part of the side surface of the lower pattern PTb, an empty space (ES) can be formed.

[0181] The touch insulation layer 820 extends and is disposed in the routing wiring region RK of the first region PH, the first pattern portion PT1, the dam portion DM, and the second pattern portion PT2, and can be disposed in contact with the upper surface of the touch buffer layer 800 on the touch buffer layer 800 on the second pattern portion PT2 and the hole dam HDM.

[0182] A protective layer 60 is disposed between the touch buffer layer 800 and the touch insulation layer 820 in the region between the plurality of patterns PT of the first pattern portion PT1, so that the touch buffer layer 800 and the touch insulation layer 820 can be separated.

[0184] The protective layer 60 can be made of at least one or more organic insulating substances such as acrylic resin, epoxy resin, phenolic resin, polyamide resin, or polyimide resin, but is not limited thereto.

[0185] The moisture introduced through the hole region H penetrates into the voids (ES) formed in the patterns PT of the first pattern portion PT1 through the third planarization layer 850 formed of an organic substance, moves to the display region AA, and the quality of the display panel may be deteriorated.

[0186] The protective layer 60 is disposed between the plurality of patterns PT, and the touch buffer layer 800 and the touch insulation film 820 on the upper surfaces of the plurality of patterns PT may be in contact.

[0187] Even if the protective layer 60 is formed of an organic substance, it is not connected by the touch buffer layer 800 and the touch insulation film 820 on the upper surfaces of the plurality of patterns PT, so that the movement of moisture can be prevented by the protective layer 60.

[0188] In addition, by forming the protective layer 60, the distances between the voids (ES) and seams (Seam) and the third planarization layer 850 become longer, and moisture in the third planarization layer 850 cannot be transmitted.

[0189] The first height H1 from the lower surface of the lower pattern PTa to the upper surface of the upper pattern PTb of the plurality of patterns PT in the first pattern portion PT1 and the 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.
