Abstract

A display screen device may comprise a first substrate including at least a substantially transparent glass having a thickness less than or equal to 1.1 millimeters; an anti-reflective thin film coating; and a second substrate including a touch screen device. Additionally, a method for providing a display screen device is disclosed.

Claims

1. A display screen device, comprising:

a first substrate including at least a substantially transparent textured, etched alumino-silicate glass having a thickness of about 0.5 millimeters, said textured, etched alumino-silicate glass reduces an amount of reflected specular light on a surface of the first substrate;

an anti-reflective thin film coating applied to the first substrate;

a second substrate including a touch screen device, the second substrate being laminated to the first substrate, the touch screen device of the second substrate detects a location of a touch in a display area of said second substrate; and

an exterior oleophobic coating.

2. The display screen device of claim 1, wherein said anti-reflective thin film coating comprises:

an anti-reflective coating stack.

3. The display screen device of claim 1, wherein said second substrate including a touch screen device comprises:

an outer screen of a flat panel display touchscreen.

4. The display screen device of claim 1, further comprising:

a hydrophobic coating.

5. The display screen device of claim 1, further comprising:

a conductive coating for reducing electro-magnetic interference.

6. A flat panel display unit, comprising:

a first substrate including at least a substantially transparent textured, etched alumino-silicate glass having a thickness of about 0.5 millimeters, said textured, etched alumino-silicate glass reduces an amount of reflected specular light on a surface of the first substrate;

an anti-reflective thin film coating applied to the first substrate;

a second substrate including a touch screen device, the second substrate being laminated to the first substrate, the touch screen device detecting a location of a touch in a display area of said second substrate;

a flat panel display including at least one of a third substrate, a fourth substrate, a liquid crystal layer embedded between third and fourth substrates, or a backlight assembly;

an exterior oleophobic coating; and

at least one printed circuit board.

7. The flat panel display unit of claim 6, wherein said anti-reflective thin film coating comprises:

an anti-reflective coating stack.

8. The flat panel display unit of claim 6, wherein said second substrate including a touch screen device comprises:

an outer screen of a flat panel display touchscreen.

9. The flat panel display unit of claim 6, further comprising:

a hydrophobic coating.

10. The flat panel display unit of claim 6, further comprising:

a conductive coating for reducing electro-magnetic interference.
