Embodiment
Below in conjunction with drawings and Examples, the utility model is described in detail:
Consult Fig. 1, Fig. 2 and Fig. 3, the utility model comprises every an embodiment of empty induction-type backlight Keysheet module 10: light emitting module 1, light guide plate module 2, support structure Slab element group 3, electrical function film unit group 4, push-button unit group 5, induction chip 6, and a mains switch 7.
This light emitting module 1 comprises light-emitting component 11 and a wire 12 of a lengthwise open, and one end of this wire 12 is electrically connected on this light-emitting component 11, and the other end of this wire 12 is then electrically connected on this mains switch 7.In the present embodiment, this light-emitting component 11 is a light-emitting diode (LED), certainly also can be other light source, is not limited with the light source that the present embodiment discloses.
This light guide plate module 2 is arranged at above this light emitting module 1, and the light level homogenizing that this light-emitting component 11 can be sent and up guide disperse.Support structure Slab element group 3 is then arranged at above this light guide plate module 2, and it is made for iron plate or aluminium sheet, and can support this electrical function film unit group 4 and this push-button unit group 5.
This electrical function film unit group 4 is arranged at above this support structure Slab element group 3, and has a substrate 41, multiple trigger point 42, and an induction line 43.This substrate 41 has flexible circuit board, these trigger points 42 to be arranged at spaced reciprocally respectively on this substrate 41 and can to produce the signal of telecommunication of corresponding different keypad function setting, this induction line 43 to be also installed on this substrate 41 and around these trigger points 42, and this induction line 43 forms an electric field around this electrical function film unit group 4.
This push-button unit group 5 is arranged in this electrical function film unit group 4, and comprise the button 51 of quantity these trigger points 42 corresponding, these buttons 51 are arranged at the position of these trigger points 42 corresponding respectively, and each button 51 has the known structure such as a keycap and an elastic component, does not add to repeat at this.Trigger point 42 below it can be touched to produce the corresponding signal of telecommunication when user presses any button 51.
This induction chip 6 is arranged at this electrical function film unit group 4, and is electrically coupled with this induction line 43.In the present embodiment, this induction chip 6 is arranged at this electrical function film unit group 4, but this induction chip 6 also can with this light emitting module 1 at same layer or be arranged at a circuit board (not shown), not as limit.And this induction chip 6 can detect the change of the electric field that this induction line 43 is formed and resolve, whether to control this light emitting module 1 luminescence further, that is, this induction chip 6 is utilize the principle of electric field induction automatically to control this light emitting module 1 with this induction line 43.Specifically, consult Fig. 3 and Fig. 4, this mains switch 7 is electrically connected on this induction chip 6 and this light emitting module 1, when the hand 8 of a user is in time being somebody's turn to do every empty induction-type backlight Keysheet module 10, this electric field that this induction line 43 is formed can be changed, and this induction chip 6 can detect the change of this electric field and open this mains switch 7 to control this light emitting module 1 luminescence, and when the hand 8 of this user detaches this every empty induction-type backlight Keysheet module 10, this electric field that this induction line 43 is formed also can be changed, now this induction chip 6 can detect the change of this electric field and to close this mains switch 7 not luminous to control this light emitting module 1.
Thus, when user is under the faint environment of light, even if do not see the letter that Chu's keyboard 51 indicates, still can luminous near control light emitting module 1 by hand 8, make Keysheet module 10 reach the effect of backlight, contribute to user's operation push-button 51.Moreover when being detached by hand 8 when user's inoperation Keysheet module 10, it is not luminous to control this light emitting module 1 that this Keysheet module 10 can close this mains switch 7 automatically, makes computer power consumption reduce, and reaches effect of carbon reduction.
Be noted that this not only can apply to notebook computer every empty induction-type backlight Keysheet module 10 especially, also can be the external connection type keyboard of the mobile device such as panel computer or similar panel computer.
In sum, collocation through induction line 43 and induction chip 6 is used, and by the principle of electric field induction, when user hand 8 near or when detaching this every empty induction-type backlight Keysheet module 10, the electric field that this induction line 43 is formed can be changed, and this induction chip 6 can detect and the change analyzing this electric field is luminous or not luminous to control this light emitting module 1, reach the effect automatically controlling backlight state, therefore really can reach the purpose of this utility model.
