Embodiment

The principle of the present invention and feature being described below in conjunction with accompanying drawing, example, only for explaining the present invention, is not intended to limit the scope of the present invention.

Fig. 1 is the structural representation of mobile terminal according to one embodiment of present invention, a kind of mobile terminal as shown in Figure 1, this mobile terminal comprises the glass cover-plate being disposed adjacent successively, contact panel and display panel, wherein, glass cover-plate comprises first area and the 2nd region in addition of the Touch Zone covering contact panel 8, this mobile terminal also comprises the first flexible PCB 7, 2nd flexible PCB 5 and mainboard (not shown), first flexible PCB 7 is electrically connected contact panel 8 and mainboard respectively, 2nd flexible PCB 5 is electrically connected mainboard, as shown in Figure 3, 2nd flexible PCB 5 is attached at the 2nd region on glass cover-plate 6. can selection of land, two region of the 2nd flexible PCB 5 except being attached on glass cover-plate 6, is also attached at the first area in the 2nd region closed on. also namely the 2nd flexible PCB 5 is attached on glass cover-plate, also relates to first area except relating to the 2nd region.

In the present embodiment, the function key of the corresponding mobile terminal in the 2nd region. To scheme, the 2nd region that the 2nd flexible PCB 5 attaches, corresponding three function keys 3, such as " return key ", " home key ", " menu key ".

Wherein, the part in the 2nd region that above-mentioned 2nd flexible PCB 5 is attached on glass cover-plate is provided with circuit trace (not shown), similar, corresponding three function keys 3, such as " return key ", " home key ", " menu key ". this mobile terminal also comprises driving chip, this driving chip is used for whether detection occurs to touch control (such as in the 2nd region, whether detection occurs to touch control in the function key of the corresponding mobile terminal in the 2nd region), the detection of this driving chip is attached at the change (change of resistance value and/or capacitance) of the capacitance-resistance of the circuit trace of the 2nd flexible PCB 5 in the 2nd region, when user carries out touching control in the 2nd region, this driving chip sends the variable signal of the capacitance-resistance detected to other element, for other components and parts, as optionally, this driving chip can be attached on the 2nd flexible PCB 5.

As shown in Figure 1 and Figure 5, the 2nd flexible PCB comprises head and afterbody, and the head of the 2nd flexible PCB is located at the 2nd region, and the afterbody of the 2nd flexible PCB bends inwards and is electrically connected with mainboard.

As shown in Figures 2 and 3, the top of above-mentioned first flexible PCB is provided with hard contact, and hard contact and contact panel on the first flexible PCB are electrically connected, and the bottom of contact panel 8 and the bottom of display panel 9 are put down together.

As shown in Figure 1 and Figure 4, above-mentioned first flexible PCB is T-shaped, as optionally, first flexible circuit board can also be made other shape to meet the layout of mobile terminal inside, such as " 7 " font, its afterbody is drawn from the right side of it, it is also possible to make anti-" 7 " font, by its afterbody from drawing on the left of it. Above-mentioned hard contact is located at the head (region that namely top of the first flexible PCB is wider) of T-shaped first flexible PCB.
