Description
display device
[0001] The present disclosure relates to a display device that displays an image by combining modules in which self-luminous light-emitting elements are mounted on a substrate.
[0002] A display device is a type of output device that visually displays data information such as characters, shapes, and images.
[0003] Typically, liquid crystal panels (LCDs) that require backlighting are used as display devices, while OLED (Organic Light-Emitting Diode) panels, which are made of a film of organic compounds that emit light on their own in response to current, are mainly used. However, LCD panels have slow response times, consume a lot of power, and are difficult to compact because they do not emit light themselves and require a backlight. Furthermore, OLED panels do not require a backlight because they emit light themselves, and can be made thin. However, if the same screen is displayed for a long time, it is vulnerable to burn-in (deterioration), where a certain part of the previous screen remains as it is when the screen is changed as the lifespan of the subpixels expires.
[0004] Accordingly, research is being conducted on micro light-emitting diode (microLED or μLED) display panels that mount inorganic light-emitting elements on a substrate and use the inorganic light-emitting elements themselves as pixels as new panels to replace them.
[0005] A micro light-emitting diode display panel (hereinafter, micro LED panel) is one of the flat panel display panels and is composed of a plurality of inorganic light-emitting diodes (inorganic LEDs), each of which is 100 micrometers or less in size.
[0006] These LED panels are also self-luminous devices, but as they are inorganic light-emitting devices, they do not suffer from the burn-in phenomenon of OLEDs and have excellent brightness, resolution, power consumption, and durability.
[0007] Compared to liquid crystal display (LCD) panels that require backlighting, microLED display panels offer better contrast, response time, and energy efficiency. Both organic light-emitting diodes (OLEDs) and inorganic light-emitting diodes (MLEDs) are energy efficient, but MLEDs offer greater brightness, luminous efficacy, and a longer lifespan than OLEDs.
[0008] In addition, by arranging LEDs on a circuit board in pixel units, display modularization can be produced on a board-by-board basis, and it is easy to produce various resolutions and screen sizes to suit consumer orders.

[0049] Hereinafter, preferred embodiments according to the present disclosure will be described in detail with reference to the attached drawings.
[0050] FIG. 1 illustrates a display device according to one embodiment of the present disclosure. FIG. 2 illustrates an exploded view of the main components of the display device according to one embodiment of the present disclosure. FIG. 3 illustrates an enlarged cross-section of a portion of a display module of the display device according to one embodiment of the present disclosure. FIG. 4 illustrates a mounting structure of a display module and a frame of the display device according to one embodiment of the present disclosure.
[0051] Some components of the display device (1), including the plurality of inorganic light-emitting elements (50) illustrated in the drawing, are micro-unit components having a size of several μm to several hundred μm, and for convenience of explanation, the scale of some components (the plurality of inorganic light-emitting elements (50), the black matrix (48), etc.) is exaggerated.
[0052] A display device (1) is a device that displays information, data, and other information in the form of characters, shapes, graphs, images, etc., and a TV, PC, mobile, digital signage, etc. can be implemented as a display device (1).
[0053] According to an embodiment of the present disclosure, as shown in FIGS. 1 and 2, a display device (1) may include a display panel (20) for displaying an image, a board (25) for driving and / or controlling the display panel (20), a frame (90) for supporting the display panel (20), and a rear cover (10) for covering the rear of the frame (90).
[0054] The display panel (20) may include a plurality of display modules (30A-30j), a driving board for driving each of the display modules (30A-30j), and a TOCN board (Timing controller board) for generating a timing signal required for controlling each of the display modules (30A-30j).
[0055] The board (25) may include a circuit board for driving and / or controlling the display device (1). For example, the board (25) may include at least one of a power board for supplying power to the display panel (20), a control board for controlling the overall operation of the display panel (20), and a communication board for communicating with an external device.
[0056] The rear cover (10) can support the display panel (20). The rear cover (10) can be installed on the floor via a stand (not shown), or can be installed on a wall via a hanger (not shown).
[0057] A plurality of display modules (30A-30j) can be arranged vertically, horizontally, and horizontally adjacent to each other. A plurality of display modules (30A-30j) can be arranged in a matrix form of M * N. In the present embodiment, 36 display modules (30A-30j) are provided and arranged in a matrix form of 6 * 6, but there is no limitation on the number and arrangement method of the plurality of display modules (30A-30j).
[0058] A plurality of display modules (30A-30j) can be installed in a frame (90). The frame (90) can support the plurality of display modules (30A-30j). The plurality of display modules (30A-30j) can be installed in the frame (90) through various known methods, such as magnetic force using a magnet, a mechanical fitting structure, or adhesion. A rear cover (10) is coupled to the rear of the frame (90), and the rear cover (10) can form the rear exterior of the display device (1). The frame (90) can include a plurality of module openings (90a) formed to correspond to the plurality of display modules (30A-30j).
[0059] The rear cover (10) may include a metal material. Accordingly, heat generated from the plurality of display modules (30A-30j) and the frame (90) can be easily conducted to the rear cover (10), thereby increasing the heat dissipation efficiency of the display device (1).
[0060] A display device (1) according to various embodiments can implement a large screen by tiling a plurality of display modules (30A-30j).
[0061] Unlike the embodiment of the present disclosure, each of the plurality of display modules (30A-30j) can be applied to a display device. That is, the display module (30A-30j) can be installed and applied as a single unit in wearable devices, portable devices, handheld devices, and various electronic products or battlefields requiring displays, and can be applied to display devices such as monitors for personal computers (PCs), high-resolution TVs, signage, electronic displays, etc. through a plurality of assembly arrangements in a matrix type as in the embodiment of the present disclosure.
[0062] Multiple display modules (30A-30j) may have identical configurations. Therefore, the description of any one display module described below may be equally applied to all other display modules.
[0063] Among the plurality of display modules (30A-30j), the first display module (30A) may be formed in a quadrangle type, for example. The first display module (30A) may be formed in a rectangular (rectangle type) shape or a square (square type) shape.
[0064] Accordingly, the first display module (30A) may include edges (31, 32, 33, 34) formed in the up, down, left, and right directions based on the first direction (X) that is the front.
[0065] Hereinafter, for convenience of explanation, the first display module (30A) is referred to as a display module (30A), and only the first display module (30A) is described.
[0066] As illustrated in FIG. 3, the display module (30A) may include a substrate (40) and a plurality of inorganic light-emitting elements (50) mounted on the substrate (40). The plurality of inorganic light-emitting elements (50) may be mounted on a mounting surface (41) of the substrate (40) facing in the first direction (X). In FIG. 3, the thickness of the substrate (40) in the first direction (X) is shown exaggeratedly for convenience of explanation.
[0067] The substrate (40) may be formed in a quadrangle type. As described above, the display module (30A) may be provided in a quadrangle shape, and the substrate (40) may be formed in a quadrangle type to correspond thereto.
[0068] The substrate (40) can be provided in a rectangular shape or a square shape.
[0069] Accordingly, the substrate (40) may include four borders corresponding to the borders (31, 32, 33, 34) of the display module (30A) formed in the up, down, left, and right directions based on the first direction (X) that is the front.
[0070] The substrate (40) may include a base substrate (42), a mounting surface (41) forming one side of the base substrate (42), a rear surface (43) forming the other side of the base substrate (42) and positioned opposite the mounting surface (41), and a side surface (45) positioned between the mounting surface (41) and the rear surface (43).
[0071] The substrate (40) may include a TFT layer (Thin Film Transistor, 44) formed on a base substrate (42) to drive inorganic light-emitting elements (50). The base substrate (42) may include a glass substrate. That is, the substrate (40) may include a COG (Chip on Glass) type substrate. The substrate (40) may have first and second pad electrodes (44a, 44b) formed thereon so that the inorganic light-emitting elements (50) are electrically connected to the TFT layer (44).
[0072] The TFT (Thin Film Transistor) constituting the TFT layer (44) is not limited to a specific structure or type and may be configured in various embodiments. That is, the TFT of the TFT layer (44) according to one embodiment may be implemented not only as an LTPS (Low Temperature Poly Silicon) TFT, an oxide TFT, a Si (poly silicon, or a-silicon) TFT, but also as an organic TFT, a graphene TFT, etc.
[0073] Additionally, the TFT layer (44) can be replaced with a CMOS (Complementary Metal-Oxide Semiconductor) type or n-type MOSFET or p-type MOSFET transistor when the base substrate (42) of the substrate (40) is made of a silicon wafer.
[0074] The plurality of inorganic light-emitting elements (50) may be formed of an inorganic material and may include inorganic light-emitting elements having a size of several μm to several tens of μm in length, width, and height, respectively. The micro inorganic light-emitting elements may have a size in which the length of a short side among the length, width, and height is 100 μm or less. That is, the inorganic light-emitting elements (50) may be picked up from a wafer formed of a sapphire or silicon material and directly transferred onto a substrate (40). The plurality of inorganic light-emitting elements (50) may be picked up and transferred by an electrostatic method using an electrostatic head or a stamp method using an elastic polymer material such as PDMS or silicon as a head.
[0075] The plurality of inorganic light-emitting elements (50) may be a light-emitting structure including an n-type semiconductor (58a), an active layer (58c), a p-type semiconductor (58b), a first contact electrode (57a), and a second contact electrode (57b).
[0076] Although not shown in the drawing, one of the first contact electrode (57a) and the second contact electrode (57b) may be electrically connected to the n-type semiconductor (58a) and the other may be electrically connected to the p-type semiconductor (58b).
[0077] The first contact electrode (57a) and the second contact electrode (57b) may be horizontally arranged and may be in the form of a flip chip arranged in the same direction (opposite to the light-emitting direction).
[0078] The inorganic light-emitting element (50) has a light-emitting surface (54) arranged toward the first direction (X) when mounted on the mounting surface (41), a side surface (55), and a bottom surface (56) arranged on the opposite side of the light-emitting surface (54), and a first contact electrode (57a) and a second contact electrode (57b) can be formed on the bottom surface (56).
[0079] That is, the contact electrodes (57a, 57b) of the inorganic light-emitting element (50) are arranged on the opposite side of the light-emitting surface (54), and thus can be arranged on the opposite side of the direction in which light is irradiated.
[0080] The contact electrodes (57a, 57b) are arranged to face the mounting surface (41) and are electrically connected to the TFT layer (44), and a light-emitting surface (54) that irradiates light in a direction opposite to the direction in which the contact electrodes (57a, 57b) are arranged can be arranged.
[0081] Therefore, when light generated from the active layer (58c) is irradiated in the first direction (X) through the light-emitting surface (54), the light can be irradiated toward the first direction (X) without interference from the first contact electrode (57a) or the second contact electrode (57b).
[0082] That is, the first direction (X) can be defined as the direction in which the light-emitting surface (54) is positioned to irradiate light.
[0083] The first contact electrode (57a) and the second contact electrode (57b) can be electrically connected to the first pad electrode (44a) and the second pad electrode (44b), respectively, formed on the mounting surface (41) side of the substrate (40).
[0084] The inorganic light emitting element (50) can be directly connected to the pad electrodes (44a, 44b) through a bonding configuration such as an anisotropic conductive layer (47) or solder.
[0085] An anisotropic conductive layer (47) may be formed on the substrate (40) to mediate electrical connection between the contact electrodes (57a, 57b) and the pad electrodes (44a, 44b). The anisotropic conductive layer (47) may have a structure in which an anisotropic conductive adhesive is attached on a protective film and conductive balls (47a) are dispersed in an adhesive resin. The conductive balls (47a) are conductive spheres surrounded by a thin insulating film, and when the insulating film is broken by pressure, the conductors can be electrically connected to each other.
[0086] The anisotropic conductive layer (47) may include an anisotropic conductive film (ACF) in the form of a film and an anisotropic conductive paste (ACP) in the form of a paste.
[0087] Accordingly, when a plurality of inorganic light-emitting elements (50) are mounted on a substrate (40), when pressure is applied to the anisotropic conductive layer (47), the insulating film of the conductive ball (47a) is broken, so that the contact electrodes (57a, 57b) of the inorganic light-emitting elements (50) and the pad electrodes (44a, 44b) of the substrate (40) can be electrically connected.
[0088] However, although not shown in the drawing, a plurality of inorganic light-emitting elements (50) may be mounted on the substrate (40) via solder (not shown) instead of the anisotropic conductive layer (47). After the inorganic light-emitting elements (50) are aligned on the substrate (40), the inorganic light-emitting elements (50) may be bonded to the substrate (40) through a reflow process.
[0089] A plurality of inorganic light-emitting elements (50) may include a red light-emitting element (51), a green light-emitting element (52), and a blue light-emitting element (53), and the light-emitting elements (50) may be mounted on a mounting surface (41) of a substrate (40) as a unit, with a series of red light-emitting elements (51), green light-emitting elements (52), and blue light-emitting elements (53). A series of red light-emitting elements (51), green light-emitting elements (52), and blue light-emitting elements (53) may form one pixel. At this time, the red light-emitting element (51), the green light-emitting element (52), and the blue light-emitting element (53) may each form a sub-pixel.
[0090] For example, the red light emitting element (51), the green light emitting element (52), and the blue light emitting element (53) may be arranged in a row at a predetermined interval, or may be arranged in a different shape, such as a triangular shape.
[0091] The substrate (40) may include a light absorbing layer (44c) to absorb external light and improve contrast. The light absorbing layer (44c) may be formed on the entire mounting surface (41) of the substrate (40). The light absorbing layer (44c) may be formed between the TFT layer (44) and the anisotropic conductive layer (47).
[0092] The display module (30A) may further include a black matrix (48) formed between a plurality of inorganic light-emitting elements (50).
[0093] The black matrix (48) can perform a function of complementing the light absorption layer (44c) formed entirely on the mounting surface (41) side of the substrate (40). That is, the black matrix (48) can improve the contrast of the screen by absorbing external light and making the substrate (40) appear black.
[0094] The black matrix (48) may preferably have a black color.
[0095] In this embodiment, the black matrix (48) is formed to be positioned between pixels formed by a series of red light-emitting elements (51), green light-emitting elements (52), and blue light-emitting elements (53). However, unlike this embodiment, the black matrix may be formed more precisely to partition each of the light-emitting elements (51, 52, 53), which are sub-pixels.
[0096] The black matrix (48) can be formed in a grid shape with horizontal and vertical patterns to be placed between pixels.
[0097] The black matrix (48) can be formed by applying light-absorbing ink onto an anisotropic conductive layer (47) through an ink-jet process and then curing it, or by coating a light-absorbing film on the anisotropic conductive layer (47).
[0098] That is, a black matrix (48) can be formed between a plurality of inorganic light-emitting elements (50) that are not mounted on an anisotropic conductive layer (47) formed entirely on a mounting surface (41).
[0099] The display module (30A) may include a front cover (49) that is placed on the mounting surface (41) in the first direction (X) to cover the mounting surface (41) of the display module (30A).
[0100] The front cover (49) can be provided in multiple numbers so as to be formed on the display module (30A) in the first direction (X).
[0101] The front cover (49) may include a film (not shown).
[0102] The film (not shown) of the front cover (49) can be made of a functional film having optical performance.
[0103] The front cover (49) is provided to cover the substrate (40) and can protect the substrate (40) from external force.
[0104] Typically, the adhesive layer (not shown) of the front cover (49) may be provided to have a height greater than a predetermined height in the first direction (X) toward which the mounting surface (41) or the light-emitting surface (54) faces. This is to sufficiently fill a gap that may be formed between the front cover (49) and the plurality of inorganic light-emitting elements (50) when the front cover (49) is placed on the substrate (40).
[0105] A plurality of inorganic light-emitting elements (50) can be electrically connected to a pixel driving wiring (not shown) formed on a mounting surface (41) and an upper wiring layer (not shown) formed by extending through a side surface (45) of a substrate (40) and the pixel driving wiring (not shown).
[0106] The top wiring layer (not shown) can be electrically connected to the side wiring (not shown) formed on the side surface (45) of the substrate (40). The side wiring (not shown) can be provided in the form of a thin film.
[0107] The upper wiring layer (not shown) can be connected to the side wiring (not shown) by the upper connection pad (not shown) formed on the edge side of the substrate (41).
[0108] The side wiring (not shown) can extend along the side (45) of the substrate (40) and be connected to a rear wiring layer (43b) formed on the rear surface (43).
[0109] An insulating layer (43c) covering the rear wiring layer (43b) can be formed on the rear wiring layer (43b) in the direction in which the rear surface of the substrate (40) faces.
[0110] That is, a plurality of inorganic light-emitting elements (50) can be sequentially electrically connected to the upper wiring layer (not shown), the side wiring (not shown), and the rear wiring layer (43b).
[0111] Also, referring to FIGS. 3 and 4, the display module (30A) may include a driving circuit board (80) provided to electrically control a plurality of inorganic light-emitting elements (50) mounted on a mounting surface (41). The driving circuit board (80) may be formed as a printed circuit board. The driving circuit board (80) may be disposed on the rear surface (43) of the substrate (40) in the first direction (X). The driving circuit board (80) may include a plurality of chips. The driving circuit board (80) may be electrically connected to a rear wiring layer (43b) so as to be electrically connected to the plurality of inorganic light-emitting elements (50).
[0112] As the driving circuit board (80) is electrically connected to the substrate (40), the driving circuit board (80) can transmit power and electrical signals to a plurality of inorganic light-emitting elements (50).
[0113] The driving circuit board (80) can transmit a data signal to the substrate (40). The driving circuit board (80) can transmit power to the substrate (40).
[0114] For example, the drive circuit board (80) may be electrically connected to the board (25, see FIG. 2). The board (25) may be placed on the rear side of the frame (90), and the board (25) may be connected to the drive circuit board (80) via a cable at the rear of the frame (90). A cable for connecting the board (25) and the drive circuit board (80) may pass through a module opening (90a) of the frame (90). The drive circuit board (80) may include a drive connector (81) to which a cable for connecting to the board (25) is connected.
[0115] The display device (1) may include a magnetic body (70) provided on the display module (30A). The magnetic body (70) may be located on the rear surface of the display module (30A). When the display module (30A) is mounted on the frame (90), the magnetic body (70) may be provided on a surface facing the frame (90).

[0152] Referring to FIG. 20, a display module (30A) of a display device (1) according to one embodiment can be separated from a frame (90) via a jig device (160). The jig device (160) can include a jig body (161) and jig magnets (166, 167) arranged to interact with a magnetic body (70) of the display module (30A). The jig magnets (166, 167) can include a separation magnet (166) positioned on a first side of the jig body (161) and a mounting magnet (167) positioned on a second side of the jig body (161).
[0153] Referring to FIGS. 21 to 24, the magnetic pole of the portion of the separation magnet (166) attached to the display module (30A) may be arranged to be different from the magnetic pole of the portion of the mounting magnet (167) attached to the display module (30A).
[0154] Referring to FIG. 21, the control magnet (130) may be arranged to move away from the magnetic body (70) when the display module (30A) is mounted on the frame (90), as the jig device (160) including the jig magnet (166, 167) having a stronger magnetism than the control magnet (130) is attached to the display module (30A).
[0155] Specifically, in order to separate the display module (30A) from the frame (90), the jig device (160) may be positioned so that the separation magnet (166) is attached to the display module (30A). For example, the separation magnet (166) may be provided so that its south pole faces the display module (30A), and the adjustment magnet (130) of the connection device (100) may be provided so that its south pole faces the display module (30A). The magnetic force of the separation magnet (166) may be provided to be greater than the magnetic force of the adjustment magnet (130) of the connection device (100). As the separation magnet (166) approaches the magnetic body (70) provided on the display module (30A), the adjustment magnet (130), which has a relatively weak magnetic force, moves away from the magnetic body (70) due to the repulsive force generated between it and the separation magnet (166).
[0156] Referring to FIG. 22, the display module (30A) can be separated from the frame (90) while attached to the jig device (160) by the attractive force of the separation magnet (166) and the magnetic body (70).

The magnetic force of the mounting magnet (167) can be arranged to be greater than the magnetic force of the adjusting magnet (130) of the connection device (100). As the mounting magnet (167) moves toward the connection device (100) mounted on the frame (90) together with the display module (30A), the adjusting magnet (130) moves in a direction closer to the magnetic body (70) due to the attractive force generated between it and the mounting magnet (167).
