Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
In description of the present utility model, it will be appreciated that, term " " center ", " on ", D score, " front ", " afterwards ", " left side ", " right side ", " vertically ", " level ", " top ", " end ", " interior ", orientation or the position relationship of the instruction such as " outward " are based on orientation shown in the drawings or position relationship, only the utility model and simplified characterization for convenience of description, instead of indicate or imply that the device of indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as restriction of the present utility model.
Fig. 3, Fig. 4 are a specific embodiment of the utility model embodiment touch key-press backing structure, touch key-press backing structure in the present embodiment, comprise LCDs 1 and touch-screen 2, described touch-screen 2 is provided with touch key-press district 3, be provided with electroluminescence sheet 4 between described LCDs 1 and described touch-screen 2, described electroluminescence sheet 4 covers described touch key-press district 3.
The touch key-press backing structure that the utility model embodiment provides, arranges electroluminescence sheet 4 between described LCDs 1 and described touch-screen 2, makes the button on touch-screen 2 reach backlight effect by electroluminescence sheet 4.Electroluminescence sheet 4 is alternating voltage by being added in two end electrodes and the electric field produced, the light source of phospher luminescence, it have gently thin as a piece of paper, simple installation, can arbitrarily dismounting, reusability high, and low in energy consumption, light is soft, without ultraviolet, color is various, the life-span is long, do not produce heat.Thus, electroluminescence sheet 4 is applied in touch key-press backing structure, the thickness in key-press backlight region can be reduced, thus reduce complete machine thickness, make key-press backlight simultaneously evenly, soft, do not produce heat in work, improve the overall experience effect of user.
Further, the side surface soldered of described electroluminescence sheet 4 is on the flexible PCB of described LCDs 1, and opposite side surface is bondd by gum and touch-screen 2.Certainly, described electroluminescence sheet 4 also can nation fix on described touch-screen 2.Here the nation mentioned is the mode of a kind of routing in chip production process surely, before being generally used for encapsulation, chip internal circuits gold thread or aluminum steel are connected with package pins or the gold-plated Copper Foil of wiring board, from the ultrasonic wave (being generally 40-140KHz) of supersonic generator, dither is produced through transducer, chopper is sent to by ultrasonic transformer, when chopper contacts with lead-in wire and welded part, under the effect of pressure and vibration, metal surface to be welded phase mutual friction, oxide-film is destroyed, and there is plastic deformation, cause the metal covering close contact that two pure, reach the combination of atomic distance, final formation is firmly mechanically connected.
Because welding exists the problems such as rosin joint, dry joint, solder skip, solder joint long term exposure in routine use process on wiring board is subject to the nature such as humidity, electrostatic and human factor impact in atmosphere, causes product easily to occur short circuit, open circuit, even the situation such as to burn; Bondd by gum and easily cause the damage of touch-screen 2 and electroluminescence sheet 4; And nation determines chip is be connected with circuit board package pin by gold thread by chip internal circuits; cover by the organic material precision with special protection function again; complete later stage encapsulation; chip is subject to the protection of organic material completely; be isolated from the outside; there is not the generation of humidity, electrostatic situation, stability is higher.Thus, preferred electroluminescence sheet 4 nation fixes on touch-screen 2.
Electroluminescence sheet 4 described here is connected with the power supply of LCDs 1 or touch-screen 2 by ITO cabling, by the Power supply of LCDs 1 or touch-screen 2, be added in the alternating voltage of electroluminescence sheet 4 two end electrodes, producing electric field excites inner fluorescent substance luminous, thus makes the button on touch-screen 2 reach backlight effect.
For LCDs 1 is connected with touch-screen 2, ensure that the light that LCDs 1 the sends screen 2 that is touched to a greater degree receives simultaneously, described LCDs 1 and touch-screen 2 are bondd by OCA optical cement, there is due to optical cement the features such as high clarity, high light transmittance, high adhesion force, therefore, LCDs 1 can not only be connected with touch-screen 2 by OCA optical cement, the loss that LCDs 1 sends light can also be reduced, increase the brightness of LCDs 1, reduce energy consumption, alleviate dazzle.
For making complete machine thinner, electroluminescence sheet 4 also should be selected thinner, but excessively thin electroluminescence sheet 4 cannot ensure backlight illumination, and therefore, while guarantee brightness, make it the thinnest, the thickness of preferred electroluminescence sheet 4 is 0.05 ~ 0.5 millimeter.
The utility model embodiment still provides a kind of mobile phone, comprises the touch key-press backing structure according to any one of above-described embodiment.
The mobile phone that the utility model embodiment provides, arranges electroluminescence sheet 4, makes the button on touch-screen 2 reach backlight effect by electroluminescence sheet 4 between the LCDs 1 and described touch-screen 2 of touch key-press backing structure.Electroluminescence sheet 4 is alternating voltage by being added in two end electrodes and the electric field produced, the light source of phospher luminescence, it have gently thin as a piece of paper, simple installation, can arbitrarily dismounting, reusability high, and low in energy consumption, light is soft, without ultraviolet, color is various, the life-span is long, do not produce heat.Thus, electroluminescence sheet 4 is applied in touch key-press backing structure, the thickness in key-press backlight region can be reduced, thus reduce complete machine thickness, make key-press backlight simultaneously evenly, soft, do not produce heat in work, improve the overall experience effect of user.
The above; be only embodiment of the present utility model; but protection range of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; change can be expected easily or replace, all should be encompassed within protection range of the present utility model.Therefore, protection range of the present utility model should be as the criterion with the protection range of described claim.
