Description

Technical Field

[0001] The present invention relates to a support device for a display device, and more particularly to a support device for a display device on which an input video is displayed on a transparent screen.

Background Art

[0002] Electroluminescent display devices are roughly classified into inorganic electroluminescent display devices and organic electroluminescent display devices according to the material of the light-emitting layer. An active matrix type organic electroluminescent display device includes an organic light-emitting diode (hereinafter referred to as "OLED") that emits light by itself, and has advantages such as a fast response speed, high luminous efficiency, high brightness, and a large viewing angle. In an organic electroluminescent display device, an OLED (Organic Light Emitting Diode, referred to as "OLED") is formed in each pixel.

[0003] A transparent display device can display information and video, and can also view actual objects through a transparent display panel. Transparent display devices can be applied to various display fields such as video walls, show windows, outdoor electric billboards, as well as automobiles, public transportation, and household appliances. In particular, a transparent organic electroluminescent display device can achieve a much higher transparency compared to the transparency of existing transparent liquid crystal display devices (LCDs) due to the characteristics of a self-luminous display panel that does not require a backlight (BLU).

[0004] In the case of a general opaque display panel, since the user can see the screen of the display panel only from one direction, for example, the front direction, a drive circuit unit for driving pixels on the opposite side and a mechanism unit for placing and supporting the display panel can be arranged. However, in the case of a transparent display device having a transparent display panel as the screen, the user can see the video displayed on the pixels of the transparent display panel, and further, can see real objects and backgrounds existing outside beyond the screen of the transparent display panel. Therefore, in a display device applying a transparent display panel, it is necessary to appropriately finish the processing so that the drive circuit unit, the mechanism unit, etc. are not visible.

Summary of the Invention

Problems to be Solved by the Invention

[0005] The object of the present invention is to solve the above-mentioned necessity and / or problems.

[0006] The present invention provides a support device for a display device in which a drive circuit unit and a mechanism unit for driving a transparent display panel are made invisible from the screen of the transparent display panel.

[0007] The problems of the present invention are 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 Problems

[0008] A support device for a display device according to an embodiment of the present invention includes a transparent display panel on which an input video is displayed, a drive circuit unit for driving pixels of the transparent display panel, and a bezel frame covering bezels at the upper, lower, left, and right four edges of the transparent display panel. In the support device for a display device, side frames coupled to both left and right sides of the bezel frame; and a lower end frame coupled to the lower end of the bezel frame. Together with the drive circuit unit, signal lines and power lines electrically connected to the drive circuit unit are built in and hidden in at least one of the side frames and the lower end frame. Each of the side frames includes an opening hole formed along the length direction of the side frame between the side frame and the bezel frame.

Advantages of the Invention

[0009] In the present invention, all drive circuit units, signal lines, and power lines for driving pixels of a display panel can be hidden in side frames and a lower end frame coupled to a bezel frame covering the bezel at the periphery of the transparent display panel. The side frame can serve as a grip to facilitate holding of the display panel module when an operator couples the display panel module to implement a video wall or a tiled display, and further, can stably couple adjacent display panel modules and reinforce rigidity.

[0010] The advantages of the present invention are not limited to the advantages mentioned above, and other advantages not mentioned will be clearly understood by those skilled in the art from the description of the claims.

[0017] In the description of the embodiments, the terms 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 also be the second component within the technical concept of the present invention.

[0018] Throughout the specification, the same reference numerals refer to the same components.

[0019] The features of some embodiments can be partially or wholly combined or combined with each other, and various linkages and drives are technically possible. Each embodiment can be implemented independently of each other or can be implemented together with a correlation relationship.

[0020] Hereinafter, various embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0021] Referring to FIGS. 1 and 2, the display device of the present invention includes a transparent display panel 100 and a display panel driving unit for driving the pixels P of the transparent display panel 100.

[0022] As shown in FIG. 2, the transparent display panel 100 includes a screen 101 that reproduces an input video and through which an object or background outside the transparent display panel 100 can be seen through pixels P. The transparent display panel 100 has a length in the X-axis direction, a width in the Y-axis direction, and a thickness in the Z-axis direction. The transparent display panel 100 includes pixels P into which data of the input video is written and that emit light. Each of the pixels P includes a red (R) sub-pixel, a green (G) sub-pixel, and a blue (B) sub-pixel for the embodiment of color. Each of the pixels P can further include a white (W) sub-pixel. Each of the sub-pixels includes a pixel circuit and a light-emitting element and includes a transparent transparent portion. Therefore, as shown in FIG. 2, the user can view the video reproduced from the screen of the transparent display panel 100 and can view an object or background outside the display panel 100 through the screen of the display panel 100. When no video is displayed on the transparent display panel 100, the screen 101 of the display panel 100 looks like a transparent glass window.

[0023] The transparent display panel 100 can include a circuit layer disposed on a substrate and a light-emitting element layer disposed on the circuit layer. The transparent display panel 100 can 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 can be disposed on the screen 101 of the transparent display panel 100.

[0024] The circuit layer of the transparent display panel 100 can include pixel circuits connected to wirings such as data lines DL, gate lines GL, and power lines, a gate driving unit 120 connected to the gate lines, etc. The pixel circuit can include transistors embodied by thin film transistors (TFTs) and circuit elements such as capacitors. The light-emitting element layer includes light-emitting elements EL disposed in each of the sub-pixels respectively connected to the pixel circuits. The light-emitting element EL can be embodied as an organic light-emitting diode (OLED) or a micro light-emitting diode (micro-LED), etc.

[0025] The pixel circuit includes a light-emitting element EL, a driving element M2 that supplies current to the light-emitting element EL, a switch element M1 that connects the data line DL to the gate electrode of the driving element M2 in response to a scan pulse SCAN from the gate line GL, and a capacitor Cst connected between the gate electrode and the source electrode of the driving element M2. Each of the driving element M2 and the switch element M1 can be implemented by a transistor.

[0026] The pixel driving voltage VDD is applied to the drain electrode of the driving element M2 through the power supply line. The driving element M2 supplies current to the light-emitting element according to the gate-source voltage to drive the light-emitting element EL. The capacitor Cst is connected between the gate electrode and the source electrode of the driving element M2 to maintain the gate-source voltage of the driving element M2 during one frame period.

[0027] The display panel driving unit writes the pixel data of the input video into the sub-pixels to reproduce the input video on the screen of the display panel 100. The display panel driving unit includes a data driving unit 110 and a gate driving unit 120.

[0028] The data driving unit 110 uses a Digital to Analog Converter (hereinafter referred to as "DAC") to convert the pixel data of the input video input as digital data from the timing controller 130 into a gamma compensation voltage and outputs a data voltage DATA. The data voltage DATA is applied to the pixel circuit through the data line DL.

[0029] The gate driving unit 120 outputs a gate signal, that is, a scan signal, to the gate line GL under the control of the timing controller 130. The gate driving unit 120 can sequentially supply the scan signal SCAN to the gate line GL by shifting the scan signal SCAN using a shift register. The gate driving unit 120 can be directly formed on the display panel 100 together with the pixels.

[0030] The timing controller 130 receives pixel data of the input video and a timing signal synchronized with the pixel data from the host system. The timing controller 130 transmits the pixel data of the input video to the data driving unit 110 and controls the operation timings of the data driving unit 110 and the gate driving unit 120.

[0031] The display device further includes a power supply unit (omitted in the drawings). The power supply unit receives a DC input voltage from the host system and generates the power necessary for driving the display panel driving units 110, 120, the timing controller 130, and the display panel.

[0032] The host system can include a main circuit board such as a television system, a monitor system, a video wall system, a show window system, an electronic bulletin board system, etc., and a main power supply. A video wall combines a plurality of transparent display panels on the same plane to form one large screen. A video wall may also be interpreted as a tiled display. The host system includes a main board on which circuits such as a GPU (Graphics Processing Unit), a CPU (Central Processing Unit), a memory, a communication module, a main power supply, and a user interface are implemented. The main board of the host system can be connected to ports exposed to the outside, such as a USB port, an RJ45 port, an HDMI (registered trademark) port, an SD card port, etc. The main board can be connected to another OSD board on which an OSD (On-Screen Display) circuit is implemented and a power conversion board.

[0033] FIG. 3 is a diagram showing a drive circuit unit connected to the transparent display panel 100.

[0034] Referring to FIG. 3, the present invention includes a source board 140 connected to a transparent display panel 100, a timing control board 150 connected to the source board 140 through signal lines 144, a main board 160 of a host system connected to the timing control board 150 through signal lines 152, and a power conversion board 170 connected to the main board 160 through a power line 162. The power conversion board 170 can be connected to an external commercial AC power supply through a power line 172 and a power adapter 180. The power conversion board 170 can be integrated into the main board 160. In this case, another power conversion board 170 is not required.

[0035] The power adapter 180 can convert an AC power supply into a DC power supply and supply power to the main board 160 through the power conversion board 170. The OSD board 190 can be connected to the main board 160 through signal lines.

[0036] The source board 140, the timing control board 150, the main board 160, and the power conversion board 170 can be implemented on a PCB (Printed Circuit Board). The source board 140 can 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) including a data driving unit 110. The input end of the flexible circuit film 142 can be connected to the source board 140 through a connector, and the output end can be adhered to the input pads of the display panel 100 through anisotropic conductive films (ACF). The COF can include an IC (Integrated Circuit) in which the data driving unit 110 is integrated. The data driving unit 110 can also be directly adhered onto the substrate of the display panel 100 through an ACF. The source board 140 can include wirings for supplying video signals and power input from the main board 160 and the timing control board 150 to the display panel driving units 110, 120 and pixels.

[0037] The signal lines 144, 153, 174 and the power lines 162, 172 for connecting the circuit boards can be embodied by an FPCB, a cable, or the like. The signal line 174 can connect the ports shown in FIG. 5 to the main board 160. The timing control board 150 includes an IC on which a timing controller 130 and a power supply unit are mounted. The input end of the timing control board 150 is connected to the main board 160 of the host system to supply an input video signal and a main power supply.

[0038] The present invention includes a support device for a display device that is coupled to a periphery of a transparent display panel 100, supports the transparent display panel 100, and has a built-in drive circuit unit for driving the transparent display panel 100. The support device for a display device according to an embodiment of the present invention will be described in association with FIGS. 4 to 13.

[0039] FIG. 4 is a perspective view showing a support device for a display device according to an embodiment of the present invention. In FIG. 4, “F” indicates Front and “R” indicates Rear. FIG. 5 is a view showing in detail a front surface and a side surface of the side frame shown in FIG. 4. FIG. 6 is a view showing a circuit board built in a lower end frame.

[0040] Referring to FIGS. 4 to 7, the support device for a display device refers to a single display panel module. The single display panel module includes a bezel frame 200 that wraps around a bezel of the transparent display panel 100, and a side frame 310 and a lower end frame 500 that are coupled to the bezel frame 200 and protrude to a rear surface (or back surface) side of the transparent display panel 100. The bezel frame 200 wraps around the bezels at the upper, lower, left, and right four peripheral edges of the transparent display panel 100. The bezel frame 200 is made of metal or synthetic resin and can be coupled to the transparent display panel 100. The bezel frame 200 can be coupled to the transparent display panel 100 with screws.

[0041] The side frame 310 hides the drive circuit section so that the circuit board, signal lines, and power lines of the drive circuit section cannot be seen from the transparent screen of the transparent display panel 100. In a video wall or tiled display, when coupling the display panel modules, the side frame 310 can serve as a grip that allows the display panel modules to be easily lifted and carried. Also, in a video wall or tiled display, the side frame 310 can stably couple adjacent display panel modules and reinforce the rigidity to enable the realization of a robust large screen.

[0042] The side frames 310 are each coupled to both sides of the bezel frame 200 on the left and right sides of the transparent display panel 100 and protrude to the rear side of the transparent display panel 100. The bottom frame 500 is coupled to the bottom end of the bezel frame 200 at the bottom end of the transparent display panel 100 and protrudes to the rear side of the transparent display panel 100.

[0043] Each of the side frame 310 and the bottom frame 500 is coupled to the bezel frame 200 at an angle between 85° and 95° with respect to the rear surface of the transparent display panel 100.

[0044] At least one of the side frames 310 and the bottom frame 500 incorporates and hides all drive circuit sections for driving the transparent display panel, such as the circuit board 400 of the drive circuit section, signal lines, and power lines 410. For example, at least one of the side frames 310 incorporates and hides one or more circuit boards 400, signal lines, and power lines 410. The side frame 310 may include one or more covers 320 for opening and closing the hidden circuit board 400. The cover 320 can be detachably coupled to the stepped opening hole of the side frame 310 that exposes the circuit board 400 of the side frame 310 by a magnet or a screw.

[0045] Signal lines such as HDMI and RS45, power line 410, VLC (Visible Light Communication) line, etc. are connected to the circuit board 400 built into the side frame 310, and external media such as USB and SD cards can be inserted into the corresponding ports. The RJ45 port, USB port, HDMI port, and SD card port can be finished with a cover so as not to be exposed on the side of the side frame 310. The circuit board built into the side frame 310 can be one or more of the main board of the host system, the power conversion board, and the timing control board, but is not limited thereto. In FIG. 5, the reference numeral "411" indicates a signal line and "412" indicates a power line respectively.

[0046] As shown in FIG. 6, one or more circuit boards and signal lines are built into and hidden in the lower end frame 500. Similar to the side frame 310, the lower end frame 500 can include one or more covers that open and close the circuit board built into and hidden in the lower end frame, and the one or more covers are detachably coupled by magnets or screws. The circuit board built into the lower end frame 500 can be one or more of the source board, the timing control board, and the OSD board, but is not limited thereto.

[0047] At each lower end of the side frames 310, a connecting bracket 600 is detachably coupled. Two or more screw holes are formed in the connecting bracket 600. The upper end of the connecting bracket 600 is inserted into the internal space at the lower end of the side frame 310 and fixed to the side frame 310 with screws, and the lower end of the connecting bracket 600 protrudes below the lower end of the side frame 310. By connecting the connecting brackets 600 in this way, adjacent display panels 100 are coupled vertically. As shown in FIG. 14, the vertically adjacent display panel modules and the horizontally adjacent display panel modules can be coupled to each other through the connecting brackets 600. The display panel modules coupled in this way can be coupled in a Lego block stacking manner, so that a video wall or a tiled display can be easily installed in a desired space. RJ45, HDMI, power lines, VLC cables, USBs, SD cards, etc. can be installed on the video wall after the configuration of the video wall is completed.

[0048] The side frame 310 includes one or more opening holes 330 formed long in the longitudinal direction of the side frame 310. In each of the side frames 310, the opening hole 330 can be formed to be large enough for a hand to enter between the side frame 310 and the bezel frame 200. To ensure the opening hole 330, the side frame 310 includes at least two or more partition walls 332 protruding toward the bezel frame 200 side. The partition walls 332 can be separated from each other at a sufficient distance. For example, the partition walls 332 can be connected one by one to the ends of the upper and lower ends of the side frame 310. Additional partition walls 332 can be formed in the middle portion of the side frame 310, but are not limited thereto. The partition walls 332 can be connected to the thin bar frame 210 and the bezel frame 200. The bar frame 210 can be connected to both sides of the bezel frame 210 or integrated with both sides of the bezel frame 210. Therefore, the opening hole 330 is provided between the side frame 310 and the bezel frame 200.

[0049] In a video wall or tiled display, when the side frame 310 couples the display panel module, an operator can easily carry it by putting a hand into the opening 330 and lifting the display panel module. Therefore, the opening 330 allows the screen of the transparent display panel 100 to be visible through the side frame 310, providing an aesthetic effect and also constituting a part of the carrying grip of the display panel module.

[0050] FIG. 7 is a diagram showing an openable and closable structure of a side frame.

[0051] Referring to FIG. 7, the side frame 310 can be divided into two along the longitudinal direction so that the internal space where the drive circuit section, signal lines, and power lines are hidden can be opened and closed. For example, the side frame 310 includes a first frame 314 and a second frame 316 that is detachably coupled to the first frame 314 to open and close the internal space. The first frame 314 and the second frame 316 are coupled through a hinge 318 and can be pivoted to open and close, or can be detached by a magnet to open and close. At least one of the first frame 314 and the second frame 316 can be manufactured in a tunnel structure so as to secure the internal space of the side frame 310. When the internal space between the first frame 314 and the second frame 316 is opened, a circuit board 400, signal lines, and power lines 410 can be built in or replaced in the side frame 310.

[0052] FIG. 8 is a diagram showing a connection method in the vertical and horizontal directions of a display panel module. In FIG. 8, the arrow indicates the advancing direction of the fixing mechanism when coupling an adjacent display panel module to another display panel module through the fixing mechanism. The fixing mechanism includes a screw and a connecting bracket 600.

[0053] Referring to FIGS. 5 and 8, screw holes 334 can be formed in the side frame 310 along the thickness direction of the side frame 310 at positions pointed by the arrows in the horizontal direction. An operator can insert screws into the screw holes 334 to couple the side frames of adjacent display panel modules in the horizontal direction.

[0054] The connecting bracket 600 protruding to the lower end of the side frame 310 includes a plurality of screw holes. In the connecting bracket 600, screw holes can be formed at positions pointed by the arrow in the left - right direction. An operator can insert screws into the screw holes to couple the side frames 310 of adjacent display panel modules in the left - right direction. At this time, as shown in FIG. 14, the adjacent side frames 310 on the left and right can be coupled through the connecting bracket 600 through which the screws penetrate. The operator can insert screws into the screw holes of the connecting bracket 600 protruding below the lower end of the side frame to couple the side frames 310 of adjacent display panel modules in the up - down direction. Such a method of connecting display panel modules can connect a plurality of display panel modules in the up - down direction and the left - right direction, as if stacking Lego blocks in a video wall or a tiled display, as shown in FIGS. 9a to 13.

[0055] FIGS. 9a and 9b are diagrams showing a method of connecting display panel modules according to an embodiment of the present invention.

[0056] Referring to FIGS. 9a and 9b, four display panel modules are connected to adjacent display panel modules in the up - down and left - right directions on the same plane. The adjacent display panel modules are coupled through the side frame 310. The display panel modules adjacent in the up - down and left - right directions are coupled through the side frame 310 and the connecting bracket 600. For this purpose, the side frame 310 includes screw holes facing the screw holes of the connecting bracket 600. Through these screw holes, the adjacent side frames 310 and the connecting bracket 600 can be coupled with screws. After inserting signal lines and power lines into the side frame 310, the covers 422, 423 can cover the side openings of the side frame 310.

[0057] Figures 10a to 10d are diagrams showing a method of connecting display panel modules according to an embodiment of the present invention. The display panel modules shown in Figures 10a to 10c have a structure in which the side frames 310 can be divided into two along the length direction and opened and closed. Also, the side frame 310 includes a single opening hole 330 formed without an intermediate partition wall.

[0058] Referring to Figures 10a to 10d, a plurality of display panel modules can be connected vertically on the base plate 700. The base plate 700 can have a flat plate structure parallel to the ground. Side frames 710 can be fixedly attached vertically to both upper surfaces of the base plate 700. The side frames 710 of the base plate 700 are connected to the side frames 310 of the display panel modules through the connection brackets 600. When the desired number of display panel modules are connected, as shown in Figures 10c and 10d, the power adapter 180 is arranged in the upper surface space of the support plate 700, and the upper and side covers 730, 740 cover the internal space of the support plate 700. The power adapter 180 can be arranged in the internal space of the support plate 700 in the same number as the display panel modules so as to be connected 1:1 to the power lines of the display panel modules.

[0059] Figures 11 to 13 are diagrams showing various assembly methods in which display panel modules are connected on the same plane to implement a video wall or a tiled display. Figure 11 is a diagram showing the assembly procedure of the display panel module when connecting the display panel module on the support plate. Figure 12 is a diagram showing the assembly procedure of the display panel module when connecting the display panel module to the support plate suspended from the ceiling. Figure 13 is a diagram showing the assembly procedure of the display panel module when connecting the display panel module to the support truss. In Figures 11 to 13, 1, 2, 3, 4, 5, 6 indicate the assembly procedure.

[0060] Referring to FIGS. 11 and 12, the support plate 700 can be placed on the ground or fixed to the ceiling. After the side frame 310 of the display panel module is fixed to the side frame 710 of the support plate 700 by the connecting bracket 600, the side frames 310 of adjacent display panel modules are sequentially connected like a stack of Lego blocks. On the other hand, the support plates can be erected, and the display panel modules can be sequentially connected to these support plates in the left - right direction.

[0061] Referring to FIG. 13, the display panel module can be connected to a support truss to be implemented as a video wall. The support truss includes a vertical truss 800 erected vertically on the ground and a horizontal truss 810 connected between the vertical trusses 800. After an operator fixes the side frame 310 of the display panel module to the horizontal truss 810 with the connecting bracket 600, while raising the position of the horizontal truss 810, the display panel modules can be sequentially connected below it like a stack of Lego blocks.

[0062] FIG. 14 is a diagram showing an example in which adjacent side frames are joined in the vertical and horizontal directions by a connecting bracket.

[0063] Referring to FIG. 14, the connecting bracket 600 includes screw holes for connecting adjacent side frames 310 in the horizontal direction and screw holes for connecting adjacent side frames 310 in the vertical direction. Screws 601, 602 passing through such screw holes join adjacent side frames in the vertical and horizontal directions through the connecting bracket 600.

[0064] In the display device according to the embodiment, all the drive circuit units and the user interface for driving the transparent display panel are built into the frame of each display panel module. Therefore, the display device of the present invention can connect a plurality of display panel modules to be embodied as a video wall, and thus it is possible to reproduce an image on a large screen. Of course, it is also possible to drive a single display panel module without connecting another circuit and display an image on the single display panel module.
