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 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, wherein the support cover comprises a first region formed along a periphery of the opening, and a second region formed at a periphery of the first region and stepped higher than the first region; an adhesive layer is formed between the panel assembly and a window region corresponding to the display region; the panel assembly is bonded along an interface between the first region and the second region in such a manner that the display panel of the panel assembly comes in contact with the adhesive layer; and at least one through-hole for discharging bubbles generated between the adhesive layer and the panel assembly is formed at the interface between the first region and the second region.

2 . The curved display device of claim 1 , wherein the panel assembly comprises:
a display panel disposed under the adhesive layer and configured to display images on the display region; a fixing bracket disposed under the display panel configured to fix the display panel; a printed circuit board (PCB) disposed under the fixing bracket; and a back cover receiving the display panel, the fixing bracket and the PCB and coupled to the support cover.

3 . The curved display device of claim 1 , wherein the display panel is an LCD panel.

4 . The curved display device of claim 1 , wherein the window and the support cover are manufactured by double injection molding of different thermoplastic resins.

5 . The curved display device of claim 1 , wherein the adhesive layer is formed by applying and curing an optical adhesive composition between the window region corresponding to the display region and the first region,
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 on an upper surface of the window,
wherein the auxiliary coating layer is 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:
preparing a cover member which comprises a transparent window having a curved shape, and a light-shielding support cover formed on a lower surface 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; applying an optical adhesive composition to a lower surface of the window corresponding to the display region; and bringing the optical adhesive composition into contact with one surface of a panel assembly, wherein the support cover comprises a first region formed along a periphery of the opening, and a second region formed at a periphery of the first region and stepped higher than the first region; the panel assembly is bonded along the interface between the first region and the second region in such a manner that a display panel of the panel assembly comes in contact with the adhesive layer; and at least one through-hole for discharging bubbles generated between the adhesive layer and the panel assembly is formed at the interface between the first region and the second region.
