Accompanying drawing explanation
The following description carried out in conjunction with the drawings, the above-mentioned and other side of embodiments of the invention, feature and advantage will become clearly, in accompanying drawing:
Fig. 1 is the structural representation of mobile terminal according to an embodiment of the invention;
Fig. 2 be according to an embodiment of the invention electrostatic at the schematic diagram in mobile terminal internal discharge path.
Embodiment
Below, embodiments of the invention are described in detail with reference to the accompanying drawings.But, the present invention can be implemented in many different forms, and the present invention should not be interpreted as being limited to the specific embodiment of setting forth here.On the contrary, provide these embodiments to be to explain principle of the present invention and practical application thereof, thus others skilled in the art can understand various embodiment of the present invention and be suitable for the various amendments of certain expected application.Identical label can be used to represent identical element in whole specification with accompanying drawing.
Fig. 1 is the structural representation of mobile terminal according to an embodiment of the invention.
In the present embodiment, mobile terminal is described for mobile phone, but the present invention is not restricted to this, and such as, mobile terminal also can be panel computer (Pad) or other suitable mobile electronic devices.
With reference to Fig. 1, mobile terminal comprises according to an embodiment of the invention: be oppositely arranged and the display screen 10 be connected together and housing 20, and is arranged on the printed circuit board (PCB) (or claiming to control mainboard) 30 between display screen 10 and housing 20; Wherein, printed circuit board (PCB) 30 is connected to display screen 10, for providing electric energy and control signal to display screen.In the present embodiment, display screen 10 can be such as capacitance type touch-control panel, but the present invention is not restricted to this.
Be provided with electric sensor part 40 on the printed wiring board 30; Wherein, electric sensor part 40 is the electronic devices and components (such as electric capacity, resistance etc.) to electrostatic sensitive, i.e. this electric sensor part 40 very easily disturbed damage under the effect of electrostatic.Therefore, in order to avoid electric sensor part 40 disturbed damage under the effect of electrostatic, also be provided with electrostatic transport element 50 on the printed wiring board 30, wherein, this electrostatic transport element 50 is adjacent to electric sensor part 40, but this electrostatic transport element 50 does not contact with electric sensor part 40, and the two-terminal-grounding of this electrostatic transport element 50.Like this, electrostatic can be conducting to the earth via electrostatic transport element 50, thus can not disturb damage electric sensitive element 40.
In the present embodiment, electrostatic transport element 50 is the element be made up of a Zero-ohm resistor; But the present invention is not restricted to this, such as electrostatic transport element 50 also can for the element be in series or in parallel to form by multiple Zero-ohm resistor.
