Description
Technical field
The utility model belongs to the mobile phone field of backlights, relates in particular to a kind of mobile phone key backlight assembly.
Background technology
Along with science and technology development, people's life is more and more rich and varied, touch-screen mobile phone becomes the main flow communication tool that people select, people are to its outward appearance, display effect, the requirement of aspects such as quality parameter is also more and more higher, at present, the backlight design of touch-screen mobile phone button, be on the mobile phone pcb board the flat area source that a fixed structure is arranged as a matrix LED, and for ultra-thin big screen dimensions mobile phone, the light-emitting zone size of its button is generally very little, therefore, the space that can place the mobile phone key back light on the mobile phone pcb board is very limited, and the mobile phone key back light has certain requirement to the position of placing, these have all strengthened the design difficulty of mobile phone pcb board, influence the scientific rationality of mobile phone pcb board wiring, thereby influence the performance of mobile phone, reduce cellphone subscriber's user satisfaction.
Summary of the invention
The mobile phone key backlight assembly designs irrational technical problem to the utility model in the prior art in order to solve, and a kind of mobile phone key backlight assembly is provided.Concrete technical scheme is as follows:
A kind of mobile phone key backlight assembly comprises liquid crystal display screen FPC and for mobile phone key provides light source backlight, described liquid crystal display screen FPC comprises circuit of light sources, and described light source is connected with described circuit of light sources.
Further, described light source is arranged on the described liquid crystal display screen FPC.
Further, described light source is positioned at the side of described liquid crystal display screen FPC.
Further, comprise two described light sources, lay respectively at the relative dual-side of described liquid crystal display screen FPC.
Further, described light source is a light-emitting diode.
Further, also comprise light guiding film, described light source is close to the edge of described light guiding film.
Further, described light guiding film is colored light guiding film.
Further, described light guiding film thickness is 0.1mm ~ 0.25mm.
Mobile phone key backlight assembly of the present utility model, by circuit of light sources and light source are arranged on the liquid crystal display screen FPC, make full use of liquid crystal display screen FPC1 and gone up vacant space, reduced the difficulty of mobile phone circuit design, the wiring simple and fast, and do not influence handset capability, make the mobile phone key backlight assembly more reasonable.
Other characteristics of the present utility model and advantage will be illustrated in conjunction with the following drawings with following embodiment.
Description of drawings
Fig. 1 is the schematic diagram of the mobile phone key backlight assembly of embodiment one.
Fig. 2 is the schematic diagram of the mobile phone key backlight assembly of embodiment two.
Embodiment
Clearer for technical problem, technical scheme and beneficial effect that the utility model is solved, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Embodiment one
Fig. 1 is the mobile phone key backlight assembly schematic diagram of the utility model embodiment one, comprises liquid crystal display screen FPC1 and provides light source 3 backlight for mobile phone key, wherein liquid crystal display screen FPC1 comprises circuit of light sources 2, light source 3 is connected with circuit of light sources 2, thereby obtains power supply, for mobile phone key provides backlight.
Because the circuit on the liquid crystal display screen FPC1 is simply more a lot of than the circuit on the mobile phone PCB, and liquid crystal display screen FPC1 goes up general many than on the mobile phone PCB in vacant space, therefore, design circuit of light sources 2 is comparatively simple on liquid crystal display screen FPC1, upward the circuit trace influence is very little to liquid crystal display screen FPC1, has simplified the design of mobile phone key backlight circuit greatly.
In the present embodiment, comprise two light sources 3, lay respectively at the both sides of liquid crystal display screen FPC1, adopt the luminous mode of side, can avoid the mobile phone key point that high brightness occurs backlight, use two light sources 3, can make mobile phone key backlight bright evenly dark.
In the present embodiment, light source 3 uses light-emitting diodes, and it is little that light-emitting diode has a volume, brightness height, the little characteristics of power consumption.Because the light-emitting diodes pipe volume is little, when being placed on the liquid crystal display screen FPC1, can save the space; Because what use is that side is luminous, the characteristic of light-emitting diode high brightness can guarantee that mobile phone key is backlight enough brightness, avoids mobile phone key backlight dark excessively; Because light source 3 is placed on the liquid crystal FPC1, need to obtain power supply from liquid crystal FPC1, and the light-emitting diode power consumption is little, liquid crystal FPC1 only is required to be it provides small voltage to get final product, and light-emitting diode heating phenomenon is littler than using other light-emitting components, circuit is damaged, therefore, compare other light-emitting components, use light-emitting diode can make liquid crystal FPC1 work more stable.
Embodiment two
Fig. 2 is the schematic diagram of the mobile phone backlight assembly of embodiment two, comprise liquid crystal display screen FPC1 and and provide light source 3 backlight for mobile phone key, wherein circuit of light sources 2 is arranged on the liquid crystal display screen FPC1, light source 3 is connected with circuit of light sources 2, be with embodiment one difference: also comprise light guiding film 4, described light guiding film 4 is arranged between two light sources 3, light source 3 is close to the edge of described light guiding film 4, and (said here being close to not is only to refer to complete seamless contact, in practical set, it is inevitable a little slit occurring).The design utilizes light guiding film 4 light refraction principles, convert the point-source of light of light source 3 to area source, make the button face luminous evenly soft and can obtain high brightness, thereby and can be by changing the shape control light-emitting zone shape and size of light guiding film 4, conveniently be complementary with the mobile phone key profile.
In the present embodiment, what light guiding film 4 was selected for use is colored light guiding film, the monochromatic light that light source 3 penetrates can be become coloury polychromatic light, makes mobile phone key color backlight changeable, more attractive in appearance, improves the consumer products satisfaction.
At present, mobile phone trend slimming development, in order to make mobile phone key part backlight thinner, the thickness of light guiding film 4 is the smaller the better, but in order to guarantee that light guiding film 4 has certain leaded light ability, requires the light guiding film 4 can not be too thin again, in the present embodiment, the thickness of preferred light guiding film 4 is 0.1mm ~ 0.25mm, and this thickness is enough to guarantee light guiding film 4 leaded light abilities, can not cause too much influence to the thickness of mobile phone key-press backlight again.
Mobile phone key backlight assembly of the present utility model, by circuit of light sources 2 and light source 3 are arranged on the liquid crystal display screen FPC1, make full use of liquid crystal display screen FPC1 and gone up vacant space, reduced the difficulty of mobile phone circuit design, the wiring simple and fast, and do not influence handset capability, make the mobile phone key backlight assembly more reasonable.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model.
