Abstract

The present invention relates to a curved display device for a vehicle and a manufacturing method thereof. In one embodiment, the curved display panel for the vehicle includes: a cover member which comprises a transparent window having a curved shape and a support cover formed on the lower side of the window, and which comprises a display region defined by an opening formed in the support cover, and a non-display region excluding the display region; and a panel assembly bonded to a lower side of the support cover.

First claim

What is claimed is:

1. A curved display device for a vehicle, comprising:
a display panel assembly;
a display cover attached to the display panel assembly and covering the display panel assembly, the display cover comprising a transparent window having a curved shape and a support cover disposed over and attached to the transparent window, the support cover comprising a display hole configured to expose the display panel assembly therethrough; and
an adhesive layer disposed in the display hole and interconnecting the display panel assembly and the transparent window,
wherein the support cover comprises a front surface facing the transparent window, a rear surface facing away from the front surface and a peripheral surface surrounding the display hole and connecting the front surface and the rear surface,
wherein the support cover comprises a recessed portion that is recessed from the rear surface for receiving the display panel assembly, wherein the recessed portion comprises a bottom surface located around the display hole and facing away from the front surface, wherein the recessed portion further comprises a side surface connecting the bottom surface and the rear surface,
wherein the support cover comprises a plurality of discharging holes, each of which is formed between the side surface and the rear surface for discharging bubbles between the adhesive layer and the display panel assembly.

2. The curved display device of claim 1 , wherein the display panel assembly comprises:
a display panel disposed attached to the adhesive layer
a fixing bracket coupled to the display panel;
a printed circuit board (PCB) coupled to the fixing bracket; and
a back cover configured to receive the display panel, the fixing bracket and the PCB, wherein the back cover comprises an edge portion received in the recessed portion.

3. The curved display device of claim 2 , wherein the display panel is an LCD panel.

4. The curved display device of claim 1 , wherein the transparent window and the support cover are formed of different thermoplastic resins.

5. The curved display device of claim 1 , wherein the adhesive layer is formed of an optical adhesive composition,
wherein the optical adhesive composition comprises one or more of an optical clear adhesive (OCA) composition and an optical clear resin (OCR) composition.

6. The curved display device of claim 1 , further comprising an auxiliary coating layer formed over an upper surface of the transparent window,
wherein the auxiliary coating layer comprises an anti-finger coating layer, an anti-glare coating layer or an anti-reflective coating layer.

7. The curved display device of claim 1 , wherein the support cover has a light-shielding property.

8. A method for manufacturing a curved display device for a vehicle, the method comprising:
providing a display panel assembly;
providing a display cover comprising a transparent window having a curved shape and a support cover disposed over and attached to the transparent window, the support cover comprising a display hole, wherein the support cover comprising a front surface facing the transparent window, a rear surface facing away from the front surface and a peripheral surface surrounding the display hole and connecting the front surface and the rear surface, wherein the support cover comprises a recessed portion that is recessed from the rear surface for receiving the display panel assembly, wherein the recessed portion comprises a bottom surface located around the display hole and facing away from the front surface, wherein the recessed portion further comprises a side surface connecting the bottom surface and the rear surface, wherein the support cover comprises a plurality of discharging holes, each of which is formed between the side surface of the recessed portion in a direction away from the recessed portion;
applying an optical adhesive composition to a surface of the transparent window in the display hole; and
bringing the display panel assembly into contact with the optical adhesive composition such that the optical adhesive composition is the transparent window and the display panel assembly,
curing the optical adhesive composition to form an adhesive layer interconnecting the transparent window and the display panel assembly, wherein bubbles between the adhesive layer and displace panel assembly are discharged through the plurality of discharging holes.
