Abstract

A large thin display unit has a chassis structure with a first horizontally or vertically disposed enclosure, a second vertically extending enclosure mounted to the upper side of the first enclosure, and a third vertically extending enclosure mounted above the first enclosure behind the second enclosure. The second enclosure has an opening that opens toward a front of the unit and has a margin along the perimeter of the opening. The thin display section is fixed to the margin in a vertical position. Further, an air route is formed between the third enclosure and a planar portion of the second enclosure, and an air route is formed between the thin display section and the planar portion of the second enclosure. Also, a wiring space is formed between the thin display section and the planar portion of the second enclosure. Preferably, the thin display section is a large liquid-crystal display provided with a plurality of backlights.

Claims

1. A thin display unit, comprising:

a body extending longitudinally having height and width dimensions that are greater than a depth dimension of the body, a first enclosure at a bottom portion of the body, a second enclosure in front of a portion of the first enclosure having a planar portion extending in the longitudinal direction, and a third longitudinally extending enclosure located above a rear portion of the first enclosure and behind the second enclosure;

a power supply section stored in the first enclosure,

a thin display section mounted in the second enclosure in front of the planar portion of the second enclosure, and

a vertical substrate having components for operating said thin display unit that is stored in the third enclosure,

wherein the second enclosure has an opening that opens toward a front of the body and a margin along the perimeter of the opening, and wherein the thin display section is fixed to the margin.

2. A thin display unit according to claim 1, further including a shock buffer mounted between the margin and the thin display section.

3. A thin display unit according to claim 2, wherein the shock buffer is one of a resilient material and a spring.

4. A thin display unit according to claim 1, wherein

the thin display section is a liquid-crystal display provided with at least one backlight.

5. A thin display unit according to claim 4, wherein

a plurality of the backlights are mounted at a side facing a display screen section of the liquid-crystal display in parallel with the display screen section.

6. A thin display unit according to claim 1, further including a stand for supporting the body that is mounted to the first enclosure, said stand having a base section and a tilt mechanism section for supporting the body so that the body can be tilted by the tilt mechanism.

8. A thin display unit according to claim 4, further including:

an upper side of the first enclosure having a first aperture and a first fan mounted adjacent the aperture for promoting air flow from the first enclosure to the third enclosure, a second aperture at an upper side of the planar portion of the second enclosure and a back case covering a rear of the body and having an exhaust port formed on the upper side of the back case for exhausting the heat passing through the first and second apertures to outside of the body.

9. A thin display unit according to claim 5, further including a second fan mounted adjacent said second aperture for promoting air flow through said second enclosure.

7. A thin display unit, comprising:

a body extending longitudinally having height and width dimensions that are greater than a depth dimension of the body, a first enclosure at a bottom portion of the body, a second enclosure in front of a portion of the first enclosure having a planar portion extending in the longitudinal direction, and a third longitudinally extending enclosure located above a rear portion of the first enclosure and behind the second enclosure;

a power supply section stored in the first enclosure,

a thin display section mounted in the second enclosure in front of the planar portion of the second enclosure, and

a vertical substrate having components for operating said thin display unit that is stored in the third enclosure,

an air route formed between the third enclosure and the planar portion of the second enclosure,

wherein the second enclosure has an opening that opens toward a front of the body and a margin along the perimeter of the opening and the thin display section is fixed to the margin, and

wherein an air route is formed between the thin display section and the planar portion of the second enclosure.

10. A thin display unit comprising:

a body extending longitudinally having height and width dimensions that are greater than a depth dimension of the body, a first enclosure at a bottom portion of the body, a second enclosure in front of a portion of the first enclosure having a planar portion extending in the longitudinal direction, and a third longitudinally extending enclosure located above a rear portion of the first enclosure and behind the second enclosure;

a power supply section stored in the first enclosure,

a thin display section mounted in the second enclosure in front of the planar portion of the second enclosure, and

a vertical substrate having components for operating said thin display unit that is stored in the third enclosure,

wherein the third enclosure has a third unit-storing section arranged by having a wiring space between the third enclosure and the planar portion of the second enclosure to store a vertical substrate,

wherein the third enclosure is arranged to deviate to one side from the second enclosure so that the wiring space and the third enclosure are in parallel with each other, and

further including a connecting terminal at the wiring space side,

a back case covering the wiring space and opening downwardly, and a removable wiring cover concealing the connecting terminal.
