Fig. 2 is the enlarged drawing of A in Fig. 1.
The realization of the utility model object, functional characteristics and advantage will in conjunction with the embodiments, are described further with reference to accompanying drawing.
Wherein, 10-FPC wiring board; 101-holding wire; 102-golden finger pad; 1021-crosses tin hole; 20 display screen fixed frames; 30-display screen; 40-display screen PIN.
Embodiment
Below with reference to drawings and the specific embodiments describe in detail the technical solution of the utility model so as clearer, understand invention essence of the present utility model intuitively.
Fig. 1 is the using state figure of the FPC golden finger pad syndeton of the utility model backlit display screen; Fig. 2 is the enlarged drawing of A in Fig. 1.
Shown in composition graphs 1 and Fig. 2, the FPC golden finger pad syndeton of a kind of backlit display screen provided by the utility model, Welding Structure mainly between traditional pad and display screen PIN is improved, and fractures when there is bending to prevent relevant golden finger pad.
Specifically, the FPC golden finger pad syndeton of a kind of backlit display screen provided by the utility model, comprises FPC wiring board 10, display screen fixed frame 20, display screen 30 and display screen PIN 40.
Wherein, described display screen 30 is fixed in described display screen fixed frame 20, and the link of described display screen PIN 40 is connected with described display screen 30 signal, and described display screen PIN 40 is between described display screen fixed frame 20 and display screen 30; Described FPC wiring board 10 is laid with holding wire 101 and golden finger pad 102, the link of described golden finger pad 102 is electrically connected with described holding wire 101.The utility model improves and is: described golden finger pad 102 misplaces with described display screen PIN 40 and is connected, to make the link of described golden finger pad 102 between the end and described display screen fixed frame 20 of described display screen PIN 40, the end of described golden finger pad 102 is between the link and the end of described display screen PIN 40 of described display screen PIN 40.
So, FPC golden finger pad 102 syndeton of a kind of backlit display screen 30 provided by the utility model, traditional pad entire length is shortened, make the link of described golden finger pad 102 between the end and display screen fixed frame 20 of display screen PIN 40, described golden finger pad 102 end is between the link and the end of display screen PIN 40 of display screen PIN 40.
And then, make firm welding between described golden finger pad 102 and described display screen PIN 40, namely, when bending occurs convenient described FPC wiring board 10, the stress produced also can not concentrate on display screen 30 edge or display screen fixed frame 20 edge, makes not easily to fracture.
It is emphasized that, in the present embodiment, distance L1 between the link of described golden finger pad 102 and described display screen fixed frame 20 is set as 0.15-0.2mm, in the technical program, the distance L1 between the link of described golden finger pad 102 and described display screen fixed frame 20 is specifically set as 0.2mm.
