Problems solved by technology

[0006] 2. In terms of physical characteristics: experiments conducted by IBM Corporation in Japan have proved that plastic materials have zero shielding effect on electromagnetic waves, unless they are electroplating or metal layers; and because plastic materials cannot conduct electricity and cannot eliminate static electricity, there is often static electricity remaining
[0008] 4. In terms of melting point: ABS has a melting point of 90°C, and PC has a melting point of 160°C, which is not heat-resistant and easily produces toxic substances
[0010] 6. In terms of the requirements of international organizations: it is difficult to recycle plastic casings, and it will increase the cost of recycling and pollute the environment, which will eventually cause harm to human health. The use of

Embodiment Construction

[0048] As shown in Figures 1 to 3, the present invention is applied to a liquid crystal display, and the structure of the liquid crystal display includes: a casing 10 composed of a front frame 11 and a rear cover 12; a liquid crystal panel (LCD) 21 and a circuit that can display a picture The component 20 set in the display of the board 22; it is mainly because the casing 10 is made of magnesium alloy or aluminum alloy by die-casting, and can be directly assembled with the component 20 set in the display, so the existing plastic shell display can be saved for assembling components. The accompanying metal fixing parts achieve the effect of quick assembly and reduced assembly cost, and derive many special effects through the material properties of magnesium alloy or aluminum alloy. In addition, the casing 10 is provided with a grounding wire 13 to connect to the grounding electrode 14 , to eliminate static electricity. This will be described in detail below.

Abstract

The related Mg-/Al-alloy outer shell for plasma or LC TV comprises: a die-casting front frame, a die-casting back cover, and some screw structures on pre-set position for fixing display member. This invention has super strength and heat resistance, saves material, convenient to recycle, and can also ground for eliminating static electricity.

Description

technical field [0001] The invention relates to a casing for displays such as LCD TVs, plasma TVs and desktop displays made of magnesium alloy / aluminum alloy die-casting, in particular to a casing made of magnesium alloy or aluminum alloy die-casting and placed in a predetermined place. A screw connection structure is provided to directly assemble with the components in the display, so as to save a lot of metal fixing parts, which can quickly assemble and save assembly costs, and because the materials are cheap and recyclable, the cost of materials can be reduced. Background technique [0002] With the advancement of technology, traditional CRT TVs will gradually be replaced by liquid crystal displays. The main reason is that the thinner liquid crystal panel (LCD) of liquid crystal displays makes the overall volume smaller than traditional CRT TVs, and the mature manufacturing technology reduces the price. , and then attract consumers' desire to buy, so the market for liquid...
