Background technology
With the continuous development of science and technology, mobile phone is quickly updating, and the mobile phone species of in the market is also very more
Sample, consumer also requires more and more higher for mobile phone using cruising time, need in operation to light for mobile phone key by
Light source under key causes button is illuminated could use, and the design quantity of light source affects cruising time.
There are many situations, positive attractive in appearance neat in order to ensure, touch key-press will often need to be arranged in accordingly according to ID
To ensure the attractive in appearance of machine and coordinate, and for internal structure of mobile phone, often there is barrier the inside of key position for position,
Such as many situations be key layout within the frame region of screen, this is designed the guide-lighting of button is influenceed.
Traditional key light guide design：First, FPC is transferred by multiple metal clips and mainboard, top electroluminescent lamp is arranged
On FPC, the leaded light of key area is realized by plane light guiding film；Second, by increasing plastic cement leaded light block and reflective sheeting,
The light of light emitting source is transferred to key area to realize by plane light guiding film.It can be seen that both schemes, manufacturability is complicated, material
It is more, the deficiencies of cost is high.Even some also ensure the light guide effect of button by sacrificing outward appearance, inadvisable.And both are passed
Very cost limited and inner space is limited again for system design, and this is undoubtedly the problem of very big.
Existing push-button light guiding film typically pushes up emitting led lamp as light source so as to meet character luminous area brightness value using six
Topology requirement, LED quantity is more, and power consumption is more, and caused heat is double, and cost expense is double, and existing button is led
The original scheme of light film reaches luminous effect using printing net-point technique on tpu films, and the utilization rate of light is low, and brightness is weak,
With the growth of usage time, light guiding film jaundice is more serious.
Utility model content
The purpose of this utility model is to provide a kind of push-button light guiding film module, to solve what is proposed in above-mentioned background technology

Button, FCB and reflection site are touched, side-emitting LED lamp, the side-emitting LED lamp upside are provided with the FPC FPCs
PET partitions are provided with, metal clips is provided with the PET partitions, maylar films are provided with the upside of the metal clips, it is described
Transparent double face glue is provided with the upside of maylar films, is set on the upside of the transparent double face glue and is pasted with light guiding film, in the light guiding film
Reflection site is provided with, photomask is provided with the upside of the light guiding film, touch key-press is provided with the upside of the photomask.
Preferably, the side-emitting LED lamp is symmetricly set in the both sides of FPC FPCs.
Preferably, the side-emitting LED lamp design quantity is four.
Preferably, the membrane material of the light guiding film is made of the pc polyester films of high conduction.
Preferably, the reflection intensive regular array in site is in light guiding film.
Compared with prior art, the beneficial effects of the utility model are：The push-button light guiding film module is provided with side-emitting LED lamp
Quantity is four, and relatively design reduces quantity in the past, changes design structure and has met character luminous area brightness value structural requirement,
LED quantity reduces 1/3, and power consumption subtracts 1/3, improves the time of battery durable, and the membrane material for the light guiding film being provided with is passed using high
The pc polyester films led, on the surface of membrane material by the way of mould heat pressure processing optical site, cost is low, and stability is good, hair
Light is uniform.
