Abstract

The present disclosure relates to a display device where unit liquid crystal display devices are easily assembled for a volumetric display or a multi display by applying a chamfer structure to a side surface portion of the unit liquid crystal display device. The display device includes a plurality of unit liquid crystal display devices, each having a liquid crystal panel, a backlight unit under the liquid crystal panel, a top frame over the liquid crystal display panel, and a main frame surrounding a side surface of the backlight unit. The liquid crystal panel is one the main frame. Additionally, at least one side surface portion of each of the plurality of unit liquid crystal display devices has a chamfer structure.

Claims

1. A display device comprising:

a plurality of unit liquid crystal display devices,

wherein each of the plurality of unit liquid crystal display devices comprises;

a liquid crystal panel;

a backlight unit under the liquid crystal panel;

a top frame over the liquid crystal display panel, the top frame including a first slanting portion covering a side surface of the liquid crystal panel and a first horizontal portion covering an edge of a front surface of the liquid crystal panel, the first slanting portion having a first acute angle with respect to the first horizontal portion, the first slanting portion having a combining portion; and

a main frame wrapping around a side surface of the backlight unit and having the liquid crystal panel thereon, the main frame including a second slanting portion wrapping around the side surface of the backlight unit and a second horizontal portion supporting the liquid crystal panel, the second slanting portion having a second acute angle with respect to the second horizontal portion, the second slanting portion including a fastener member accommodating portion,

wherein at least one side surface portion of each of the plurality of unit liquid crystal display devices have a chamfer structure,

wherein the combining portion is disposed in the fastener member accommodating portion,

wherein the first and second slanting portions are connected to each other in the fastener member accommodating portion using a fastener member,

wherein the fastener member accommodating portion is a screw head accommodating portion, and

wherein the fastener member is a screw having a screw head.

2. The display device of claim 1, wherein the screw head accommodating portion includes a first surface parallel to the second horizontal portion and a second surface perpendicular to the first surface, and

wherein the combining portion includes a first fixing portion parallel to the first surface and a second fixing portion contacting the second surface.

3. The display device of claim 1, wherein the top frame includes a plurality of separated parts, and

wherein the plurality of separated parts are individually assembled to the main frame.

4. The display device of claim 1, wherein the main frame further includes a vertical portion protruding from the second horizontal portion, and

wherein the vertical portion wraps the side surface of the liquid crystal panel.

5. The display device of claim 1, further comprising a bottom frame under the backlight unit,

wherein the bottom frame includes a horizontal surface and a slanting surface connected to an edge of the horizontal surface to have an obtuse angle with respect to the horizontal surface.

6. The display device of claim 1, wherein each of the plurality of unit liquid crystal display devices has a polygonal shape.

7. The display device of claim 1, wherein the display device includes one of a volumetric display and a multi display.

8. The display device of claim 7, wherein the volumetric display includes one of a tetrahedral display device, a hexahedral display device, an octahedral display device, a dodecahedral display device and an icosahedral display device.

9. The display device of claim 8, wherein each of the plurality of unit liquid crystal display devices of the tetrahedral display device has a triangular shape.
