Problems solved by technology

The present situation is that the forming process of the case cannot provide a forming machine capable of forming a transparent case with high precision for a flat-panel display device having a large display screen of, for example, 30 inches or more. Special process for precision forming
In the forming process, there are the following problems: it is difficult to form a high-precision finished shell with no obvious weld line, so the forming efficiency and yield are low, and the cost is high because the forming mold price is very high
In a flat panel display device, there is a problem that the luminous flux decreases due to light leakage from the light guide member and the display efficiency of the optical display portion decreases.
In addition, in the flat panel display device, since the leaked light irradiates the internal components and the like to become bright, it can be seen from the front, so there is a problem that the display effect is reduced.

Embodiment Construction

[0031] Next, a flat-panel display device (hereinafter abbreviated as a display device) 1 shown in the drawings as an embodiment of the present invention will be described in detail. The display device 1 is a color plasma display panel (hereinafter referred to as a color PDP). 2 TV receivers for larger screens and thinner models used as display panels. Such as figure 1 As shown in the display device 1 , speakers 4A and 4B are respectively assembled on the left and right side parts of the display device main body 3 having a horizontally long rectangular front shape, and the display device main body 3 is supported by the bracket member 5 . The display device 1 arranges the front glass 6 in a state superimposed on the front portion of the color PDP 2 as will be described in detail later, and covers the frame portion 6a with a horizontally long rectangular shape formed by black ceramic printing on the inner surface of the front glass 6 . The effective display screen area P of the...

Abstract

A flat-panel display device, which seeks to reduce the housing, reduce the cost of parts, improve the assembly performance, and achieve a thinner profile. Utilize the first bracket part (12) and the second bracket part (13) that are assembled on the first frame part (7) and the second frame part (8) to keep the upper edge and the lower edge, and put the two ends In the state fitted in the matching groove (14) of the sound box (4), the combination of the color PDP2 and the front glass (6) is maintained by the third bracket part (15) and the fourth bracket part (16).

Description

technical field [0001] The present invention relates to a flat-panel display device having a large display screen and a light-weight and thin display panel. Background technique [0002] Flat-panel display devices include light-weight and thin display components such as plasma display panels (PDP: plasma display panels, hereinafter abbreviated as PDPs), liquid crystal displays, or electroluminescent light source display panels. Compared with the cathode ray tube (CRT: cathode-raytube), the display screen is larger, lighter and thinner. For example, the color PDP display device not only realizes a large display screen of 50 inches or more, but also has the characteristics of good image quality and light weight that can be used as a wall-mounted type. It is used as a receiver for high-definition TV broadcasting and digital TV broadcasting. Attention has been paid to various large display devices (Patent Document 1). [0003] A color PDP display device, as is well known, incl...
