Abstract

A portable computer including a housing having first and second sections, the first section having an information input device and the second section having a case having a first fastening element; a display panel including a second fastening element at a rear surface of the panel, the case and the display panel being attached through the first and second fastening elements; a hinge coupling the first and the second sections to each other; and a display panel support member having a third fastening element, the display panel support member being attached to the display panel through the third fastening element.

Claims

1. A flat panel display device mounted to a housing including a front part and a rear part, the flat panel display device comprising:

a backlight;

a flat display panel, having a display area;

a first frame covering an entire rear surface of the backlight;

a second frame; and

a hinge arm between the first frame and the housing, the hinge arm including a through-hole, wherein the flat display panel and the backlight are disposed between the first frame and the second frame, the first frame including a screw hole behind the display area at a rear surface of the first frame, wherein the backlight is disposed between the first frame and the flat display panel, and the flat display panel is disposed between the backlight and the second frame, the first frame being fixed to the rear part of the housing with the screw hole at the rear surface of the first frame and a screw at the rear part of the housing, wherein the screw is inserted into the screw hole from an exterior of the housing via the through-hole, and wherein the flat display panel conceals the screw, the through-hole and the screw hole in a viewing direction.

2. The flat panel display device as recited in claim 1 further comprising:

a light guide, wherein the first frame is adjacent to the light guide.

3. The flat panel display device as recited in claim 1 further comprising:

a reflector plate, wherein the first frame is immediately adjacent to the reflector plate.

10. The flat panel display device of claim 1, the display area including an active region and an inactive region, wherein the screw hole fastening part is behind the active region of the display area.

11. The flat panel display device of claim 1, the display area including an active region and an inactive region, wherein the screw hole is behind the inactive region of the display area.

4. A flat panel display device comprising:

a flat display panel having a display area;

a backlight;

a front frame;

a rear frame having side surfaces, a rear surface and lateral edges formed where the side surfaces join the rear surface, wherein the rear surface of the rear frame includes a fastening hole and covers an entire rear surface of the backlight;

a housing having a front portion and a rear portion; and

a fastener fixing the rear frame to the rear portion of the housing the fastening hole associated with the rear surface of the rear frame and a fastening hole on the rear frame; and

a hinge arm between the rear frame and the housing, the hinge arm including a through-hole, wherein the flat display panel and the backlight are disposed between the front and rear frames, wherein the backlight is disposed between the rear frame and the flat display panel, and the flat display panel is disposed between the backlight and the front frame, wherein the fastener is behind the display area, wherein the fastener is inserted into the fastening hole from an exterior of the housing via the through-hole, and wherein the flat display panel conceals the fastener, the through-hole and the fastening hole in a viewing direction.

5. The flat panel display device of claim 4, wherein the fastening hole associated with the rear surface of the rear frame is located adjacent to the lateral edge.
