Attachable frame for flat display panels

The present invention relates to an attachable frame for flat display panels adopted for use on liquid crystal display (LCD) devices and plasma display devices that has separable elements to shorten test and repairs time and simplify the process.

With rapid progresses of modem time and rising of people's living standard, these days people have growing demands on life quality. This also reflects in electronic products. For instance, flat display device has become one of the most popular products on the market at present. Almost all major vendors have plunged into the flat display device market.

Conventional flat display devices generally have a front frame and a back cover that are fabricated in an integrated manner. The flat display panel is sandwiched therebetween. While the integrated front frame and back cover may be mass-produced at a lower cost, the current trend of flat display panel gradually focuses on larger sizes, and molding cost is expensive and time-consuming. In response to various dimensions and length and width ratios, different molds have to be prepared. With increasing number of flat display panel dimensions, the number of molds also increase. The cost burden becomes very heavy. In addition, change of production lines also involves change of molds to be used, and that takes time. As the molds usually are heavy and bulky, it takes a great deal of human efforts to do the work. Assembly and positioning also are difficult.

Therefore the primary object of the invention is to provide a frame which consists of a main structure, a bracing structure, a front frame and a rear frame that are separable. The main structure, bracing structure, front frame and rear frame may be adjusted according to the dimension and length and width ratio of the panel, and are assembled to become the frame of the flat display panel.

Another object of the invention is to provide a power supply connecting electrically to the flat display panel. The power supply may be located in a housing chamber formed in the speakers mounted on two sides of the flat display panel and be covered by a covering sheet, or be housed in a space formed between the rear frame and the flat display panel to be hidden to enhance the appealing of the entire body. The power supply may also be separated from the flat display device to suit different safety regulations of various countries to simplify product test process.

The foregoing, as well as additional objects, features and advantages of the invention will be more readily apparent from the following detailed description, which proceeds with reference to the accompanying drawings.
