Description

The present invention relates to a support device for a display device.

Electroluminescent displays are broadly divided into inorganic light-emitting displays and organic light-emitting displays, depending on the material of the light-emitting layer. Active matrix type organic light-emitting displays include organic light-emitting diodes (OLEDs) that emit light themselves, and have the advantages of a fast response speed, high light-emitting efficiency, brightness, and wide viewing angle. In organic light-emitting displays, an OLED (organic light-emitting diode, OLED) is formed in each pixel.

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

A transparent display device includes a transparent display panel and various opaque electronic components connected to the transparent display panel. Appropriate support processing is required so that the opaque electronic components are not visible on the screen of the transparent display panel.

The present invention aims to solve the above-mentioned needs and/or problems.

The present invention provides a support device for a display device that prevents opaque electronic components connected to a transparent display panel from being seen.

The objectives of the present invention are not limited to those mentioned above, and other unmentioned objectives will be clearly understood by those skilled in the art from the following description.

A display device support device according to one embodiment of the present invention 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 display device support device including a first frame covering the periphery and corners of the display panel; and a second frame coupled to the first frame at the predetermined angle.

The first circuit board is disposed within the second frame and is hidden by the second frame.

A display device support device according to another embodiment of the present invention includes a plurality of display panels on which an input image is displayed in pixels, a plurality of flexible circuit films connected to each of the display panels, and a plurality of first circuit boards connected to the flexible circuit films connected to each of the display panels, the display device support device including a plurality of first frames covering the periphery and corners of each of the display panels; one or more second frames connected to the first frame at the predetermined angle at each of the display panels; a plurality of fixing brackets connected to the first frame at each of the display panels; and a plurality of support trusses connected to the fixing brackets to fix the display panels.

Two or more of the support trusses are connected along the width of the display panel, and have a length that is at least twice as long as the width of a single display panel.

A support device for a display device, in which the first circuit board is disposed within the second frame and is hidden by the second frame.

The present invention reduces the size of the bezel of the display panel and enlarges the screen by hiding the 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 periphery and corners of the display panel.

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

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.

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.

The present invention allows the cable management cover to be used to connect and disconnect cables to the circuit board without disassembling the frame.

The present invention utilizes corner frames and fixed brackets to connect the display panel and attach the display panel to the support truss.

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.

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

Referring to FIG. 1 and FIG. 2, the display device of the present invention includes a display panel 100 and a display panel driver for driving pixels P of the display panel 100.

The display panel 100 includes a screen 101 that reproduces an input image and through which real external objects are viewed via pixels P. In a transparent display device, the screen 101 may be a transparent screen through which real external objects are viewed through the display panel 100, as shown in FIG. 2.

The 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 display panel 100 includes pixels P in which input image data is written and emits light. Each pixel P includes a red (R, R) subpixel, a green (G, G) subpixel, and a blue (B, B) subpixel to realize a color. Each subpixel includes a pixel circuit and a light-emitting element, and includes a transparent part. Therefore, as shown in FIG. 2, a user can see an image reproduced from the screen of the display panel 100, and can see the real object 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.

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 polarizer disposed on the encapsulation layer. A touch sensor may be disposed on the screen 101 of the display panel 100.

The display panel 100 may be, but is not limited to, a transparent display panel in a transparent display device.

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 element layer may include light emitting elements, for example OLEDs, each connected to a pixel circuit. Hereinafter, the light emitting elements are exemplified as OLEDs.

The OLED includes an organic compound layer formed between the anode and the 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.

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 implemented as a transistor.

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 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 the forward voltage between the anode electrode and the cathode electrode is equal to or greater than the 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.

The display panel driver writes pixel data of the 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.

The data driver 110 converts the pixel data of the input image 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.

The gate driver 120 outputs a gate signal, i.e., a scan signal, to the gate line GL under the control of the timing controller 130. The gate driver 120 can sequentially supply the scan signal SCAN to the gate line GL by shifting the scan signal SCAN using a shift register.

The timing controller 130 receives pixel data of an input image and a timing signal synchronized with the pixel data from the host system. The timing controller 130 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.

The display device further includes a power supply unit, which is omitted in the drawing. The power supply unit generates the voltages required to drive the display panel drivers 110 and 120 and the pixel circuits.

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 shop window system, an electronic display system, etc.

Figure 3 shows a circuit board connected to the display panel 100.

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

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 a FPCB (Flexible PCB). The input end of the flexible circuit film 142 may be connected to the first circuit board 140 through a connector, and the output end may be attached to the 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 also be directly attached to 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, 120 and pixels.

The output end of the first circuit board 140 may be connected to the 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. The input end of the second circuit board 150 is connected to the main circuit board of the host system to receive an input video signal and a main power supply.

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

As shown in FIG. 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 within a frame coupled to the display panel 100. Preferably, the first circuit board 140 can be fixed at an angle that is 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.

The display device support device according to an 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°, with respect to the display panel 100, preferably a perpendicular plane. 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.

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

Referring to Figures 5a and 5b, the support device includes a first frame 200 that encloses 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.

A plurality of first frames 200 may be coupled to the display panel 100. As shown in FIGS. 6 to 8, the first frame 200 includes a main frame 202 that covers the front edge and side of the display panel 100, a sub-frame 204 that covers the rear edge of the display panel 100, and a corner frame 206 that covers the rear corners of the display panel 100.

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.

The sub-frame 204 and the corner frame 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 frame 206 cover the rear periphery and rear corners of the display panel 100.

The sub-frame 204 may be made of a straight flat plate structure that covers the 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 made in the shape of a corner of the display panel 100. The corner frame 205 may be made of the same structure and may be shared.

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 the 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. Thus, 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.

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

Referring to Figures 9 and 10, the circuit board 140 and the cable 144 are disposed within the second frame 300.

The second frame 300 may be coupled to one or more of the first frames 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.

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 with the first circuit board 140 and the cable 144 sandwiched between them.

The base plate 302 can be removably fixed at an angle between 80° and 100° to the subframe 204 on one side of the first frame 200 and the corner frames 206 arranged on both sides of the subframe 204. The base plate 302 can be fixed to the subframe 204 and the corner frames 206 of the first frame 200 by screws or magnets, or can be separated from those frames 204, 206.

The base plate 302 provides a space for accommodating the first circuit board 140 and the cable 144. 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 provided by the flat portion and the side walls 302a. The cable 144 is disposed side by side on a surface within the base plate 302 that forms a predetermined angle, for example, an angle between 80° and 100°, from the first frame 200.

As shown in Figures 18 and 19, the base plate 302 may further include a partition 309 that divides the cable 144 on a plane and prevents the cable 144 from becoming entangled.

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

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.

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 portion 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.

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 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 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 side wall of the base plate 302 by a screw or a magnet and 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.

Referring to FIG. 11 and FIG. 12, the display device support device of the present invention may further include a stand 220 that is detachably connected to the first frame 200. The stand 220 is connected 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.

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 that is exposed to the outside is small.

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

The display device support device according to the second embodiment of the present invention can realize a large screen by combining multiple display panels 100 in a multi-vision form. Such a display device can be applied to large screen display devices such as video walls, show windows, and outdoor electronic billboards.

Figure 17 is a perspective view showing in detail the structure of the second bracket by enlarging part G in Figure 15. Figure 18 is an exploded perspective view showing the fixed bracket connected to the frame and the hollow of the support truss connected to the fixed bracket.

Referring to FIG. 13 to FIG. 18, the display device support device according to an embodiment of the present invention further includes a plurality of support trusses 400 for combining a plurality of display panels 100 into a large screen, and a plurality of fixing brackets 510, 520 for fixing the support trusses 400 to the first frame 200.

Two or more support trusses 400 are connected along the width direction Y of the display panel 100, and have a length at least twice as long as the width direction of the display panel 100. 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 the truss upper end connection part 430 and the floor plate 440.

The support truss 400 supports the display panels 100 on a flat surface. Therefore, the screens of the display panels 100 can be combined on a flat surface to realize a large screen.

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.

The fixed brackets are divided into a plurality of first fixed brackets 510 connected to the lower corners of the first frame 200 and a plurality of second fixed brackets 520 connected to the upper corners of the first frame 200.

Each of the display panels 100 is coupled to the first and second frames 200, 300 as described above. The fixing brackets 510, 520 are removably coupled to the corners of the first frame 200 in each of the display panels 100 by screws. The support truss 400 is removably coupled to the fixing brackets 510, 520. The support truss 400 is coupled to the fixing brackets 510, 520 to support the multiple display panels 100.

The first fixing bracket 510 includes a cable groove that forms a hidden cable path for the second frame 300. The support truss 400 includes a hollow 402 that is connected to the hidden cable path for the second frame 300 to provide a hidden cable path for the cable 144 to pass through. Thus, the cable 144 connected to the first circuit board 140 passes through the hidden cable path that is connected along the internal space of the second frame 300, the cable groove of the first fixing bracket 510, and the hollow 402 of the support truss 400 without being exposed to the outside.

The fixing brackets 510, 520 may be formed with openings that expose the cables for connecting the cables along a hidden cable path and bending or shuffling the cables. The fixing brackets 510, 520 may further include a second management cover 530 that covers the openings of the fixing brackets 510, 520.

Figure 19 is a perspective view showing the structure of the first fixed bracket 510 in detail. Figure 20 is a perspective view showing the structure of the second fixed bracket 520 in detail.

Referring to FIG. 19, the first fixing bracket 510 includes upper and lower horizontal connecting parts 513, 514 of a predetermined length, first and second side walls 511, 512 vertically connected at both ends of the horizontal connecting parts 513, 514, and a cable groove 515 provided between the horizontal connecting parts 513, 514.

The upper and lower horizontal connectors 513, 514 have a length greater than the diameter of the support truss 400. A cable groove 515 is formed between the horizontal connectors 513, 514 through which the cable 144 passes. The cable 144 extends along the hidden cable path of the second frame 300, bends at a right angle from the first fixed bracket 510, and extends along the cable groove 515 toward the support truss 400.

The first side wall 511 is removably connected to the first frame 200, particularly the lower corner frame 206, with screws to secure the first fixing bracket 510 to the first frame 200. The second side wall 512 is spaced apart alongside the first side wall 511. The second side wall 512 is removably connected to the support truss 400 with screws to secure the support truss 400 to the first fixing bracket 510.
