Embodiment
Present pre-ferred embodiments is provided, to describe technical scheme of the present invention in detail below in conjunction with accompanying drawing.
Embodiment 1:
The present embodiment relates to a kind of mobile terminal, Fig. 2 is the schematic diagram of the touch key-press of the touch-screen of the mobile terminal of the present embodiment, the touch-screen of described mobile terminal is the capacitive touch screen of G+F type, as shown in Figure 3, its touch pad comprises glass layer 21, OCA(OpticalClearAdhesive from top to bottom successively, optical cement) layer 22, ITO(IndiumTinOxides, indium tin oxide) layer 23 and film layer 24, and on described film layer 24, be also attached with the FPC plate 25 that is provided with IC chip (not shown).LED lamp control module is provided with, for controlling LED luminescence after receiving drive singal in described IC chip.
The present invention changes in this area usual manner when carrying out backlight design, no longer LED is arranged on the pcb board of mobile phone, and no longer adopts light-guiding pillar to carry out leaded light.
As shown in Figure 4, in the present embodiment, at least one pair of metal dish 241 is all coated with in the region that the lower surface of described film layer 24 is corresponding with each touch key-press, region corresponding with touch key-press is herein generally touch key-press orthographic projection to the region, relevant position on described film layer 24, certainly, allow to there are some position deviations in practice.Every a pair metal dish 241 all specifically can adopt silver powder by high-strength conductive glue 242() paste a top light emitting LED lamp 243, the reflective membrane 244 and surface of each top light emitting LED lamp 243 has all been sticked.
The reason all arranging pair of metal dish 241 for each top light emitting LED lamp 243 is because top light emitting LED lamp 243 has two electrodes (anode and negative electrode), in order to make two electrodes pushing up light emitting LED lamp 243 can both conducting, need to arrange pair of metal dish 241, can be connected with a metal dish 241 respectively to make two electrodes.
And described metal dish 241 adopts high-strength conductive glue 242 to paste described top light emitting LED lamp 243, thus serves good fixation to described top light emitting LED lamp 243, also serve good electric action simultaneously.
When user carries out contact action to described touch-screen, IC chip on described FPC plate 25 will detect contact action, thus produce feedback signal and transmit it in the CPU of mobile terminal, CPU will send described drive singal to the LED lamp control module in described IC chip after receiving feedback signal, after described LED lamp control module receives described drive singal, described top light emitting LED lamp will be controlled luminous, again by the effect of reflective membrane 244, uniform light is just made to be irradiated on the button silk-screen of touch key-press.
And in the present invention, by changing the setting position of LED, and corresponding improvement has been carried out to hardware circuit corresponding on the touch pad of touch-screen and software control, thus make top light emitting LED lamp 243 be arranged on same structural member with touch key-press, the relative distance of the two is greatly reduced relative to prior art, so just makes the light in the region of touch key-press very even.And pushing up light emitting LED lamp 243 is set up on a touchpad, makes light path greatly shorten, thus also solves light leakage phenomena well.Meanwhile, project organization of the present invention is simple, and cost also greatly reduces, and improves the utilance of the inner space of touch-screen.
In the present embodiment, the type of described capacitive touch screen can also be G+F+F, G+G or OGS, and described top light emitting LED lamp 243 also can adopt side-emitting LED lamp to substitute, and described metal dish 241 specifically can adopt aluminium dish or copper dish.
Embodiment 2:
The present embodiment relates to the mobile terminal that a kind of touch-screen is the capacitive touch screen of G+F type equally, and as shown in Figure 3, the laminated construction of the touch pad of its touch-screen is identical with the structure of the touch pad of the mobile terminal in embodiment 1.In the present embodiment, directly at least one PN junction of regional ensemble that the lower surface of described film layer 24 is corresponding with each touch key-press, also namely directly utilize semiconductor technology to make luminous PN junction at respective regions, then around PN junction, do shading treatment.
In the present embodiment, the IC chip on described FPC plate 25 comprises a PN junction control module, for after receiving a drive singal, controls described PN junction luminous.
Like this, when user carries out contact action to described touch-screen, IC chip on described FPC plate 25 will detect contact action, thus produce feedback signal and transmit it in the CPU of mobile terminal, CPU will send described drive singal to the PN junction control module in described IC chip after receiving feedback signal, after described PN junction control module receives described drive singal, described PN junction will be controlled luminous, thus uniform light is irradiated on the button silk-screen of touch key-press.
Compared with embodiment 1, in the present embodiment, the distance of described luminous PN junction and touch key-press is less, and light path therebetween also shortens more, thus solves the problem of backlight inequality and light leak better, and effect is also more remarkable.
Although the foregoing describe the specific embodiment of the present invention, it will be understood by those of skill in the art that these only illustrate, protection scope of the present invention is defined by the appended claims.Those skilled in the art, under the prerequisite not deviating from principle of the present invention and essence, can make various changes or modifications to these execution modes, but these change and amendment all falls into protection scope of the present invention.
