Abstract

A flat panel display assembly structure includes a back plate, an upper cover and a plastic frame. The back plate comprises a rectangular flat plate and a first side wall extending upwards along the four sides of the flat plate, wherein the first side wall is provided with at least one first opening. The upper cover comprises a rectangular frame and a second side wall extending downwards along the four sides of the frame, and the second side wall is provided with at least one second opening. The rubber frame is arranged between the back plate and the upper cover and is provided with at least one fastener which extends downwards from the edge of the rubber frame. The fastener comprises a first plate and a second plate which is attached to the surface of the first plate. When the rubber frame is assembled between the back plate and the upper cover, the first plate is matched in the first opening, and the second plate is matched in the second opening, so that the first side wall is tightly close to the second side wall. Therefore, the defect of the traditional flat panel display assembling structure is overcome, and the thickness of the side edge is greatly reduced so as to meet the requirement of reducing the appearance size of the flat panel display.

Description

Reduce the assembled planar display structure of sidewall thickness

Technical field

The invention relates to a kind of package assembly of flat-panel screens, especially a kind of package assembly that can reduce sidewall thickness.

Background technology

Along with the making thin-film electronic crystal technology is progressive fast, LCD has been owing to possessed advantages such as frivolous, power saving, no width of cloth ray, and a large amount of is applied to personal digital assistant's device (PDA), notebook computer, digital camera, takes the photograph in the various electronic products such as video recorder, mobile phone.Add the positive input research and development of industry and adopt the production equipment that maximizes, make the continuous lifting of quality and the price of LCD continue to descend, impel the application of LCD to enlarge rapidly.

Generally speaking, the display element of LCD can be divided into module backlight and the display panel that is installed in module backlight top.Wherein, module backlight comprises a light tube group and optical film, in order to produce the upwards emission of uniform in-plane light.Display panel comprises a color panel and an electric crystal panel, and a liquid crystal layer clamping is in wherein.Behind the shows signal input electric crystal panel, produce an electric field driven liquid crystal molecule and turn to.Planar light penetrates this liquid crystal layer and color panel, to present image.

For above-mentioned display element being assembled in the precalculated position in the LCD, design a package assembly usually to reach this purpose.Please refer to Fig. 1, this figure shows the package assembly 110 of a Typical Planar display, comprises a backboard 120, a glue frame 130 and a loam cake 140.Wherein, backboard 120 comprises a rectangular flat 122 and along the upwardly extending the first side wall 124 in dull and stereotyped 122 4 limits.Glue frame 130 is installed on the backboard 120, and has the 3rd sidewall 132 of downward extension on four limits of glue frame 130.Second sidewall 144 that loam cake 140 comprises a rectangular shaped rim 142 and extends downwards along frame 142 4 limits.

When above-mentioned backboard 120, glue frame 130 and loam cake 140 fit together, the 3rd sidewall 132 nestles up the outside surface of the first side wall 124, and second sidewall 144 nestles up the outside surface of the 3rd sidewall 132.The upper limb of the first side wall 124 is close to the lower surface of glue frame 130, makes to form a space between backboard 120 and the glue frame 130 to hold module backlight.Simultaneously, rectangular shaped rim 142 is close to the upper surface of glue frame 130, makes to form a space between glue frame 130 and the loam cake 140 to hold display panel.

It should be noted that above-mentioned package assembly 110 with backboard 120, glue frame 130 and loam cake 140 layer by layer fit fix.Therefore, as shown in Figure 2, the side thickness of this package assembly 110 is equivalent to the thickness of the first side wall 124, second sidewall 144 and the 3rd sidewall 132, and the totalling in gap therebetween.Because the size of this side thickness will influence the width of flat-panel screens display bezel, thereby under flat-panel screens now was tending towards frivolous trend, this package assembly 110 had become flat-panel screens lightening one tangible limiting factor.

In view of this, the present invention proposes a kind of package assembly of flat-panel screens, is reduced at the side thickness of known package assembly 110, to reach the purpose of further dwindling the LCD apparent size.
