Abstract
The utility model discloses a light guiding film, which comprises a layer of transparent light guiding film and light guiding points which is arranged on the transparent light guiding film and regularly distributed according to the optical principle. The light guiding points can be inserted inside the transparent light guiding film or printed on the lower surface of the transparent light guiding film. A layer of color coating layer also can be coated on the upper surface of the transparent light guiding film, and the back light with different colors can be obtained. Compared with the prior art, the transparent light guiding film has the advantages that the weight is light, the transparent light guiding film is soft, the thickness is thin, and the transparent light guiding film can not occupy the larger space. Simultaneously, the utility model can reduce the required quantity of the LED lamp, the power consumption is saved, and the back light effect is good; the utility model self has no the circuit part, the physical stability is good, the utility model is anti abrasive, and the service life is long.
Description
Technical field
The utility model relates to a kind of back light source structure, relates in particular to a kind of mobile phone component backlight source structure.
Background technology
At present mobile phone component backlight generally is to conduct by LED lamp direct irradiation or EL (EL:Electroluminescence Lamp, cold light film are called for short EL, below also with) backlight or LGP to realize.The key-press backlight of a mobile phone generally will be used the 6-8 LED lamp at least as using the LED scheme, adds outfit resistance, the cost height, and light is inhomogeneous; As can reducing the use of LED with the LGP scheme, but LGP is generally more than the thinnest 0.6mm, because the space of mobile phone is limited, LGP is used in no enough spaces, so LGP scheme pair and ultra thin handset are also impracticable; EL is the cost costliness then, and complex circuit designs makes the EL can not extensive use.
The utility model content
The utility model is in order to solve existing above-mentioned technical problem, provides that a kind of energy consumption is low, thin thickness, light guiding film simple in structure.
For addressing the above problem, the technical solution of the utility model is a kind of light guiding film of structure, comprises the layer of transparent light guiding film, is located on the transparent light guide film leaded light point by the regular distribution of optical principle.
Among first embodiment, described leaded light point is embedded in transparent light guide film inside.
Among second embodiment, described leaded light point is printed in transparent light guide film lower surface.
Wherein, also can on transparent light guide film upper surface, apply one deck color coating, can make the light of derivation send with the similar color of the color coating that applies, to obtain the backlight of different colours.
The transparent light guide film thickness is generally 0.125mm between 0.1mm-0.3mm.The leaded light point of being located on the transparent light guide film can be made of a kind of leaded light point of shape, also can be constituted by two or more difform leaded light point.Leaded light point can be covered with whole transparent light guide film or only be located at the part of transparent light guide film.
The utility model by on one deck printing opacity light guiding film by optical principle regular the leaded light point is set, when light shines, change angle of reflection, so that light can positively penetrate by leaded light point.Compared with prior art, the printing opacity light guiding film has light weight, softness, thin thickness can not take advantage than large space, with metallic film button (MDF:Metal Dome Foil also claims film key, button shell fragment, the young sheet of pot, Dome sheet etc.) combination the time, do not influence Dome sheet pressing touch.The utility model reduces LED lamp requirement simultaneously, saves power consumption, and general small size backlight only needs two side LED lamps to get final product, and is backlight respond well; No circuit part own, physical stability is good, and is wear-resistant, long service life.

The specific embodiment
As shown in Figure 1, figure is the basic structure of the utility model first embodiment, and a kind of light guiding film comprises layer of transparent light guiding film 1, is located on the transparent light guide film 1 the leaded light point 2 by the regular distribution of optical principle.Transparent light guide film 1 thickness is generally 0.125mm, and this numerical value can have certain deviation, also can adjust, but general transparent light guide film 1 thickness is between 0.1mm-0.3mm.It is various that leaded light is put 2 shapes, and square leaded light point 2, circular leaded light point 2, broken line type leaded light point 2, stripe-shaped leaded light point 2, erose leaded light point 2 etc. are arranged.Leaded light on the transparent light guide film 1 is put 2 shapes, the area size can be made various variations, and the leaded light point 2 on the transparent light guide film 1 can be made of a kind of leaded light point of shape, also can be constituted by two or more difform leaded light point 2.According to the leaded light needs, leaded light point 2 can be covered with whole transparent light guide film 1, also can only be located at certain part on the transparent light guide film 1 on demand simultaneously.
As shown in Figure 1, among first embodiment, leaded light point 2 is circular leaded light point 2, circular leaded light point 2 according to optical principle regular be embedded in transparent light guide film 1 inside.As being light source, when light shines, change angle of reflection, so that light can penetrate (with reference to Fig. 5) from transparent light guide film 1 upper surface by circular leaded light point 2 with LED lamp 4.
As shown in Figure 2, among second embodiment, leaded light point 2 is square leaded light point 2, square leaded light point 2 according to optical principle regular be printed in transparent light guide film 1 lower surface.Square leaded light point 2 is printed on the formation of transparent light guide film 1 lower surface for the light guide ink of height reflection and high refraction, changes angles of reflection by square leaded light point 2, so that light can penetrate (with reference to Fig. 6) from transparent light guide film 1 upper surface.
As apply the color coating 3 of different color and lusters at printing opacity light guiding film 1 upper surface, can obtain the backlight of different colours.Shown in Fig. 3,4, be coated with one deck color coating 3 at transparent light guide film 1 upper surface of first embodiment, second embodiment, color coating 3 can determine its color and luster on demand, can obtain the backlight of different colours by color coating 3.
As shown in Figure 7, when the utility model is used, with mobile phone thin film press-key and light guiding film combination, cell phone mainboard only need be equipped with two side-emitting LED lamps 4, and film key and light guiding film are fitted on the PCB6, the conducting that promptly keeps film key, push functions such as feel, the LED lamp 4 that also makes two spot lights reaches whole good effect backlight by the light guiding film conducting light, the cost of having realized mobile phone backlight parts reduces, and saves the backlight power consumption.Compare with existing light conducting plate structure, printing opacity light guiding film 1 has light weight, softness, thin thickness can not take advantage than large space, overcomes the difficult problem that backlight is used.With the metallic film key combination time, do not influence Dome sheet 5 pressing touch.
The utility model reduces LED lamp requirement, saves power consumption, and general small size backlight only needs two side LED lamps to get final product, and is backlight respond well; No circuit part own, physical stability is good, and is wear-resistant, long service life.
