The present invention relates to an assembly structure of a flat display device, especially an assembly structure capable of reducing the thickness of a side wall. Previous technology: With the thin-film transistor equipped with various thin and light, power-saving digital assistant (PDA) mobile phones and other electronic products, the use of large-scale production cells has continued to decline, prompting, in general, the liquid installed on the backlight module tube group And the optical film panel includes a colored surface. Display signal input Steering. Flat light transmission To design the above display, a typical flat display 130 and an upper cover 140 are usually assembled. Along the flat 1 2 2 four sides # volume production technology rapid progress, due to the 'no ray and other advantages, a large number of applications in personal pen-type computers, digital cameras, camcorders, lines < in. Coupled with the industry's active investment in research and development and ^ f ', the quality of liquid crystal displays is constantly improved and the price is high. "The application field of displays is rapidly expanding. The display elements of "Yi" are divided into backlight modules and "", and display panels. Among them, the backlight module includes a lamp 2 which generates a uniform plane light to be emitted upward. Display | ~ Transistor panel, a liquid crystal layer is sandwiched between it: after the body panel, an electric field is generated to drive the liquid crystal molecules 1. The day-to-day layer and the shirt color panel to display the image. Clams are assembled at predetermined positions in the LCD monitor, and the thickness is as small as ΐ. Please refer to the figure _, showing the beans and structure 11 〇, including a back plate 丨 2 〇, a plastic frame two, for the plate 1 2 0 including a rectangular flat plate 1 2 2, and j upper sleeve Xi Chudi-side wall 124. 130 plastic frame installation

Page 5 583430 5. Description of the invention (2) It is above the back plate 120 and has third side walls 1 3 2 extending downward on the four sides of the plastic frame 130. The upper cover 1 4 0 includes a rectangular frame 1 4 2 and second side walls 1 4 4 extending downwardly along the four sides of the frame 1 4 2.

When the back plate 120, the plastic frame 130 and the upper cover 140 are assembled together, the third side wall 1 3 2 is abutted against the outer surface of the first side wall 1 2 4, and the second side wall 1 4 4 is fastened against the second The outer surface of the side wall 1 3 2. The upper edge of the first side wall 1 2 4 is closely attached to the lower surface of the plastic frame 130, so that a space is formed between the back plate i 2 0 and the plastic frame 1 30 to accommodate the backlight module. At the same time, the rectangular frame 142 is closely attached to the upper surface of the plastic frame 130, so that a space is formed between the plastic frame 130 and the upper cover 140 to accommodate the display panel.
