Embodiment
First embodiment
Shown in the 2a～2d figure, in the present invention, the framework 2000 of LCD unit 200 is provided with the keeper 5000 of engineering plastics (being thermoplastics in the present embodiment) system, in the present embodiment, keeper 5000 is columnar protrusions, and is provided with a pilot hole 3010 corresponding to this keeper 5000 on flexible circuit board 3000.
The fixing means of flexible circuit board of the present invention shown in Fig. 2 a～Fig. 2 d, comprises the following steps:
Shown in Fig. 2 a, with the pilot hole on the flexible circuit board 3,000 3010 in alignment with the keeper on the framework 2,000 5000; Secondly shown in Fig. 2 b, flexible circuit board 3000 is attached on the framework 2000 via adhesive tape 4000, at this moment, keeper 5000 passes pilot hole 3010 and protrudes in flexible circuit board 3000; Then shown in Fig. 2 c, heat and pressurize with 7000 pairs of keepers 5000 of a hot-press arrangement; At last shown in Fig. 2 d, keeper 5000 is after heating and pressurization, and distortion and become flat and a portion that fuses 9000 that diameter is bigger than pilot hole can be fixed in flexible circuit board 3000 on the framework 2000 whereby.
Through the LCD unit 200 after the above steps processing as shown in Figure 3, it is characterized in that: TFT panel 1000 is carried on the framework 2000, and by the affixed mode of this kind, the reliability that flexible circuit board 3000 combines with framework 2000 increases.
Second embodiment
Shown in Fig. 4 a, one stiffening plate 6000 is set on flexible circuit board 3000 in the present embodiment, this stiffening plate has a through hole 6010 corresponding to this pilot hole 3010, when flexible circuit board 3000 fitted on the framework 2000, keeper 5000 can pass pilot hole 3010 simultaneously and protrude on the stiffening plate 6000 with through hole 6010.The flat that keeper 5000 pressurization back forms fuses portion 9000 ' meeting and flushes with stiffening plate 6000, and its reason is that the design of through hole 6010 can hold flat material partly behind keeper 5000 pressurizeds.
The design of through hole 6010 lists two kinds in the present embodiment, but is not limited thereto two kinds of designs, as long as flat material partly all can after can holding keeper 5000 pressurizeds.First kind of design is shown in Fig. 4 a, and the section of through hole is taper (tapered), and be gradually wide outside the flexible circuit board side direction.Second kind of design is shown in Fig. 4 b, the diameter of through hole 6010 is bigger than pilot hole 3010, and because stiffening plate 6000 has certain thickness, so the flat after keeper 5000 pressurizations fuses portion 9000 " material can be contained between the sidewall and flexible circuit board 3000 of through hole 6010.
The present invention is provided with the keeper of plastic column on the framework of liquid crystal display, form the structure of flat by heating and pressurizing, can increase flexible circuit board whereby and be fixed in fiduciary level on the framework.This structure can be saved the time of assembling, increases the fiduciary level of flexible circuit board location simultaneously.And under the environment of high temperature, also can provide the confining force better to flexible circuit board than known technology.
Though the present invention discloses as above with preferred embodiment; yet it is not in order to limit the present invention; any those skilled in the art; without departing from the spirit and scope of the present invention; certainly can do some the change and the retouching of permission, so protection scope of the present invention is worked as with being as the criterion that claims scope is defined.
