Shell for LCD TV, plasma TV and tabletop display etc made of magnesium/aluminum alloy through die casting process

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...

AI Technical Summary

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 toxic substances, (WEEE) directives emphasize the end of the product life cycle, the use of hazardous substances is harmful to the environment and health

[0011] 7. In terms of assembly: As mentioned above, the plastic casing needs to be matched with more metal fixing parts, which increases the cost of metal fixing parts and assembly

[0012] 8. In terms of appearance: the performance of the plastic case is more traditional, and it cannot show the metal texture

[0013] 9. In terms of cost: the defective products produced in the production process of plastic casings are difficult to restore, recycle and reuse, so the cost of materials is increased

[0014] As can be seen from the above, the structure of the existing display cabinets has not reached the ideal state, and thus needs to be improved.
