Description

[Technical field]

[0001] The present invention relates to a support device for a display device. [Background technology]

[0002] Electroluminescent displays are broadly classified into inorganic light emitting displays and organic light emitting displays depending on the material of the light emitting layer. An active matrix type organic light emitting display includes an organic light emitting diode (hereinafter referred to as "OLED") that emits light by itself, and has the advantages of a fast response speed, light emitting efficiency, brightness, and a wide viewing angle. In an organic light emitting display, an OLED (Organic Light Emitting Diode, hereinafter referred to as "OLED") is formed in each pixel.

[0003] Transparent display devices allow users to see real objects through a transparent display panel that displays information and images. Transparent display devices can be applied to various display fields such as video walls, show windows, outdoor electronic billboards, as well as automobiles, public transportation, and home appliances. In particular, transparent OLED displays can realize a much higher transparency than that of existing transparent liquid crystal displays (LCDs) due to the characteristics of a self-emissive display panel that does not require a backlight (BLU).

[0004] A transparent display device includes a transparent display panel and various opaque electronic components connected to the transparent display panel, and requires appropriate support to prevent the opaque electronic components from being visible through the screen of the transparent display panel. Summary of the Invention [Problem to be solved by the invention]

[0005] The present invention aims to address the above-mentioned needs and / or problems.

[0006] The present invention provides a support for a display device that prevents the view of opaque electronic components coupled to a transparent display panel.

[0007] The object of the present invention is not limited to the above-mentioned objects, and other objects not mentioned will be clearly understood by those skilled in the art from the following description. [Means for solving the problem]

[0008] According to one embodiment of the present invention, a support device for a display device includes a display panel on which an input image is displayed in pixels, a flexible circuit film connected to the display panel, and a first circuit board connected to the flexible circuit film, the support device for a display device including: a first frame covering an edge and corners of the display panel; and a second frame coupled to the first frame at the predetermined angle.

[0009] The first circuit board is disposed within and concealed by the second frame.

[0011] Two or more of the support trusses are connected along the width direction of the display panels, and have a length at least twice as long as the width direction of one display panel.

[0012] The first circuit board is disposed within and concealed by the second frame. Effect of the Invention

[0013] The present invention reduces the size of the bezel of the display panel and enlarges the screen by hiding a circuit board for driving the display panel within a second frame that is joined at a predetermined angle to a first frame that covers the edges and corners of the display panel.

[0014] The present invention also allows cables connected to the circuit board within the second frame to be hidden within the second frame.

[0015] The present invention can realize a large screen by increasing the screen size of the display panels by connecting a first frame connected to each of a plurality of display panels to a support truss that is extended in accordance with the expanded screen size through a fixing bracket.

[0016] The present invention makes it possible to hide the cables connected to each of the multiple display panels that are expanded into a large screen by hiding the cables within the fixing brackets and support trusses.

[0017] The present invention utilizes a management cover to allow cables to be connected and disconnected from the circuit board without disassembling the frame.

[0018] The present invention utilizes corner frames and fixing brackets to connect the display panel, and can connect the display panel to the support truss.

[0019] The effects of the present invention are not limited to those mentioned above, and other effects not mentioned will be clearly understood by those skilled in the art from the description of the claims. [Brief description of the drawings]

[0026] In the description of the embodiments, the terms "first", "second" and the like are used to describe various components, but these components are not limited by these terms. These terms are used merely to distinguish one component from another. Therefore, the first component referred to below may also be the second component within the technical concept of the present invention.

[0027] Like reference numbers refer to like elements throughout the specification.

[0028] The features of some of the embodiments 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 the others, or may be implemented together in a linked relationship.

[0029] Various embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0030] 1 and 2, a display device according to the present invention includes a display panel 100 and a display panel driver for driving pixels P of the display panel 100. As shown in FIG.

[0031] The display panel 100 reproduces an input image and includes a screen 101 through which external real objects are viewed through pixels P. In a transparent display device, the screen 101 may be a transparent screen through which external real objects are viewed through the display panel 100, as shown in FIG.

[0032] The display panel 100 has a length in an X-axis direction, a width in a Y-axis direction, and a thickness in a Z-axis direction. The display panel 100 includes pixels P to which input image data is written and emits light. Each of the pixels P includes a red (R, R) sub-pixel, a green (G, G) sub-pixel, and a blue (B, B) sub-pixel to realize a color. Each of the sub-pixels includes a pixel circuit and a light-emitting element, and includes a transparent part. Thus, as shown in FIG. 2, a user can view a reproduced image from the screen of the display panel 100, and can view real objects outside the display panel 100 through the screen of the display panel 100. When no image is displayed on the display panel 100, the screen 101 of the display panel 100 looks like a transparent glass window.

[0033] The display panel 100 may include a circuit layer disposed on a substrate, and a light-emitting element layer disposed on the circuit layer. The display panel 100 may further include a protective film covering the light-emitting element layer, an encapsulation layer covering the protective film, and a polarizing plate disposed on the encapsulation layer. A touch sensor may be disposed on the screen 101 of the display panel 100.

[0034] The display panel 100 can be, but is not limited to, a transparent display panel in a transparent display device.

[0035] The circuit layer may include pixel circuits connected to wiring such as data lines DL, gate lines GL, and power lines, and a gate driver 120 connected to the gate lines. The pixel circuits may include transistors implemented as TFTs (Thin Film Transistors) and circuit elements such as capacitors. The light emitting device layer may include light emitting elements, for example OLEDs, each connected to a pixel circuit. Hereinafter, the light emitting device will be exemplified as an OLED.

[0036] The OLED includes an organic compound layer formed between an anode and a cathode. The organic compound layer may include, but is not limited to, a hole injection layer (HIL), a hole transport layer (HTL), an emission layer (EML), an electron transport layer (ETL), and an electron injection layer (EIL). When a voltage is applied to the anode and the cathode of the OLED, holes that have passed through the hole transport layer (HTL) and electrons that have passed through the electron transport layer (ETL) are transferred to the emission layer (EML) to form excitons, and visible light is emitted from the emission layer (EML). The light-emitting element layer may further include a color filter array that selectively transmits red, green, and blue wavelengths.

[0037] The pixel circuit includes a light emitting element OLED, a driving element M2 that supplies a current to the light emitting element OLED, a switch element M1 that connects a data line DL to a gate electrode of the driving element M2 in response to a scan pulse SCAN from a gate line GL, and a capacitor Cst that is connected to the gate electrode and source electrode of the driving element M2. Each of the driving element M2 and the switch element M1 may be realized by a transistor.

[0038] A pixel driving voltage VDD is applied to the drain electrode of the driving element M2 through a power supply line. The driving element M2 supplies a current to the light emitting element OLED according to the gate-source voltage to drive the light emitting element OLED. The light emitting element OLED is turned on and emits light when a forward voltage between the anode electrode and the cathode electrode is equal to or higher than a threshold voltage. The capacitor Cst is connected between the gate electrode and the source electrode of the driving element M2 and holds the gate-source voltage of the driving element M2 for one frame period.

[0039] The display panel driver writes pixel data of an input image to the sub-pixels to reproduce the input image on the screen of the display panel 100. The display panel driver includes a data driver 110 and a gate driver 120.

[0040] The data driver 110 converts pixel data of an input image, which is input as digital data from the timing controller 130, into a gamma compensation voltage using a digital to analog converter (DAC), and outputs a data voltage DATA. The data voltage DATA is applied to the pixel circuit through a data line DL.

[0041] The gate driver 120 outputs gate signals, i.e., scan signals, to the gate lines GL under the control of the timing controller 130. The gate driver 120 shifts the scan signals SCAN using a shift register, so that the scan signals SCAN can be sequentially supplied to the gate lines GL.

[0042] The timing controller 130 receives pixel data of an input image and a timing signal synchronized with the pixel data from a host system, transmits the pixel data of the input image to the data driver 110, and controls the operation timing of the data driver 110 and the gate driver 120.

[0043] The display device further includes a power supply unit (not shown) that generates voltages required to drive the display panel drivers 110 and 120 and the pixel circuits.

[0044] The host system may include a main circuit board and a main power supply for a television system, a monitor system, a video wall system, a show window system, an electronic display system, and the like.

[0045] FIG. 3 is a diagram showing a circuit board coupled to a display panel 100. As shown in FIG.

[0046] Referring to FIG. 3, the present invention includes a first circuit board 140 coupled to a display panel 100 and a second circuit board 140 coupled to the first circuit board 140 .

[0047] One or more first circuit boards 140 may be connected to the display panel 100. The first circuit board 140 may be implemented as a rigid PCB (Printed Circuit Board). The first circuit board 140 may be connected to the display panel 100 through a flexible circuit film 142 such as a COF (Chip on film) or an FPCB (Flexible PCB). An input end of the flexible circuit film 142 may be connected to the first circuit board 140 through a connector, and an output end may be bonded to an input pad of the display panel 100 through anisotropic conductive films (ACF). The COF may include an IC (Integrated Circuit) in which the data driver 110 is integrated. The data driver 110 may be directly bonded on the substrate of the display panel 100 through the ACF. The first circuit board 140 may include wiring for supplying input signals and power from the second circuit board 142 to the display panel drivers 110 and 120 and pixels.

[0048] An output terminal of the first circuit board 140 may be connected to a second circuit board 150 through a cable 144. The cable 144 may be a coaxial cable. The second circuit board 150 includes an IC on which a timing controller 130 and a power supply unit are mounted. An input terminal of the second circuit board 150 is connected to a main circuit board of a host system to receive an input video signal and a main power supply.

[0049] The present invention includes a support device that can maximize the screen 101 and minimize the peripheral bezel on the display panel 100 where no image is displayed.

[0050] 4, the support device fixes the first circuit board 140 at a predetermined angle, for example, between 80° and 100°, to the display panel 100, and hides it in a frame coupled to the display panel 100. Preferably, the first circuit board 140 may be fixed at an angle substantially close to a right angle, for example, between 85° and 95°, to the display panel 100. At this time, the flexible circuit film 142 bends between the display panel 100 and the first circuit board 140.

[0051] The support device for a display device according to the embodiment of the present invention can support the cables 144 connected to the first circuit board 140 so that the cables 144 are arranged side by side on a plane that forms a predetermined angle, for example, an angle between 80° and 100°, preferably a perpendicular plane, with respect to the display panel 100. Therefore, the first circuit board 140 and the cables 144 are arranged at an angle between 80° and 100° with respect to the display panel 100 at one side edge of the display panel 100 where there is no pixel P, so that the first circuit board 140 and the cables 144 are not visible when a user looks at the screen 101.

[0052] 5a and 5b are perspective views showing a display support device according to a first embodiment of the present invention from various angles.

[0053] Referring to Figures 5a and 5b, the support device includes a first frame 200 that wraps around the periphery and corners of the display panel 100, and a second frame 300 that is connected to the first frame 200 at an angle between 80° and 100° and supports the first circuit board 140 and the cable 144.

[0054] A plurality of first frames 200 may be coupled to the display panel 100. As shown in Fig. 6 to Fig. 8, the first frame 200 includes a main frame 202 covering the front periphery and side of the display panel 100, a sub-frame 204 covering the rear periphery of the display panel 100, and corner frames 206 covering the rear corners of the display panel 100.

[0055] The structure of the main frame 202 is determined according to the shape of the display panel 100. For example, if the display panel 100 is a rectangular panel, the main frame 202 may be made of a rectangular or square frame that covers the periphery and corners of the display panel 100 on the front and side of the rectangular display panel 100.

[0056] The sub-frame 204 and the corner frames 206 are detachably coupled to the main frame 202. When the main frame 202 encases the display panel 100, the sub-frame 204 and the corner frames 206 cover the rear periphery and rear corners of the display panel 100.

[0057] The sub-frame 204 may be fabricated as a straight flat plate structure covering a straight peripheral section of the rear surface of the display panel 100, and may be detachably coupled to the straight section of the main frame 202. The corner frame 205 may be fabricated in the shape of a corner of the display panel 100. The corner frame 205 may be fabricated in the same structure and may be shared.

[0058] When the display panel 100 is a rectangular panel, each of the corner frames 205 is fabricated with a right-angle frame structure corresponding to the shape of a corner where two sides of the display panel 100 meet, and can be detachably coupled to the right-angle corner of the main frame 202. The sub-frame 204 and the corner frame 206 include screw holes 208 into which screws are inserted. Therefore, the sub-frame 204 and the corner frame 206 can be fixed to the main frame 202 or separated from the main frame 202 by screws.

[0059] The corner frame 206 may include one or more protruding bosses 210 .

[0060] 9 and 10, the circuit board 140 and the cable 144 are disposed within a second frame 300 .

[0061] The second frame 300 may be coupled to one or more of the first frame 200. The second frame 300 is not directly coupled to the display panel 100 and does not overlap the display panel 100. The circuit board 140 and the cable 144 are hidden within the second frame 300. The flexible circuit film 142 is also hidden within the second frame 300.

[0062] The second frame 300 includes a base plate 302 that is removably fixed to the first frame 200 at an angle between 80° and 100°, and a cover plate 304 that is removably coupled to the base plate 302 and covers the base plate 302 between the first circuit board 140 and the cable 144.

[0063] The base plate 302 may be detachably fixed at an angle between 80° and 100° to the sub-frame 204 on one side of the first frame 200 and the corner frames 206 disposed on both sides of the sub-frame 204. The base plate 302 may be fixed to the sub-frame 204 and the corner frames 206 of the first frame 200 by screws or magnets, or may be separated from these frames 204, 206.

[0064] The base plate 302 secures a space in which the first circuit board 140 and the cable 144 are housed. The base plate 302 includes a flat portion and side walls 302a bent from both sides of the flat portion in the longitudinal direction of the base plate 302. The first circuit board 140 and the cable 144 are disposed in the space defined by the flat portion and the side walls 302a. The cable 144 is disposed side by side on a plane that forms a predetermined angle, for example, an angle between 80° and 100°, from the first frame 200 within the base plate 302.

[0065] As shown in FIGS. 18 and 19, the base plate 302 may further include a partition 309 for partitioning the cables 144 on a plane to prevent the cables 144 from becoming entangled.

[0066] The cover plate 304 covers the open top of the base plate 302. The cover plate 304 can be fixed to or detached from the base plate 302 by screws or magnets.

[0067] The second frame 300 may further include a base plate 302 and one or more middle covers 306 , 308 disposed between the cover plate 304 .

[0068] The first middle cover 306 is detachably coupled to the base plate 302 between the base plate 302 and the cover plate 304, and covers at least a part of the first circuit board 140 placed on the flat surface of the base plate 302. The first middle cover 306 can be fixed to the base plate 302 by a screw inserted into a boss 30 protruding from the flat surface of the base plate 302, or can be separated from the base plate 302. The second middle cover 308 is detachably coupled to the base plate 302 between the base plate 302 and the cover plate 304, and covers the cable 144 placed on the flat surface of the base plate 302. The second middle cover 308 can be fixed to the base plate 302 by a screw inserted into a boss 30 protruding from the flat surface of the base plate 302, or can be separated from the base plate 302.

[0069] The second frame 300 may further include a first management cover 310. The base plate 302 may further include an opening 302b exposing the first circuit board 140 and the cable 144. The first management cover 310 may be detachably coupled to the opening 302b of the base plate 302, and may be separated from the base plate 302 when the state of the first circuit board 140 and the coaxial cable 144 needs to be inspected or replaced. The first management cover 310 may be made of a folded structure corresponding to the bottom surface and the side wall of the base plate 302 with the opening 302b of the base plate 302. The first management cover 310 may be detachably coupled to the bottom surface and the side wall of the base plate 302 by a screw or a magnet, and may be separated from the base plate 302 when the state of the first circuit board 140 and the coaxial cable 144 needs to be inspected or replaced.

[0070] 11 and 12, the support device for a display device of the present invention may further include a stand 220 that is detachably coupled to the first frame 200. The stand 220 is coupled to the lower corner frame 206 of the first frame 200 with a screw, and can support the entire display device at a predetermined height.

[0071] The display device of the present invention may further include a control box 132. A second circuit board 150 is built into the control box 132. The cable 144 extends long along a hidden cable path defined by the internal space of the second frame 200 and is connected to the control box 132. Therefore, the section of the cable 144 exposed to the outside is small.

[0072] The control box 132 may further include an opening that exposes a portion where the cable 144 and the second circuit board 150 are connected, and a cover 320 that is detachably coupled to one side of the control box 132 so as to cover the opening. The cover 320 may be detachably coupled to the control box 132 by a screw or a magnet. With the cover 320 separated from the control box 132, a user can connect the cable 144 and the second circuit board 150 and check the contact state.

[0073] The support device for a display device according to the second embodiment of the present invention can realize a large screen by combining a plurality of display panels 100 in a multi-vision form. Such a display device can be applied to a large screen display device such as a video wall, a show window, an outdoor electronic billboard, etc.

The support trusses 400 whose length is extended in the width direction of the display panel 100 are spaced apart in the length direction X of the display panel 100, sandwiching one display panel 100 therebetween, and the uppermost and lowermost ends of the spaced apart support trusses 400 can be connected to a truss upper end connector 430 and a floor plate 440.

[0077] The support truss 400 supports the display panels 100 on a plane. Therefore, the screens of the display panels 100 can be combined on a plane to realize a large screen.

[0078] The support trusses 400 can be connected to each other to extend their length and support the load of the display panel 100. Each of the support trusses 400 includes a hollow 402 into which the cable 144 is inserted, and also serves as a cable jacket.
