Embodiment
The present invention will be described in detail with reference to the accompanying drawings and examples.
As shown in figure 1, the utility model discloses a kind of key-press backlight component, including photomask 1, diaphragm 2, light guiding film
3 and luminescence component 4, the photomask 1 there is front surface A and back surface B, the lamp of light-conductive hole 11 and first is offered on the photomask 1
Position hole 12, the light-conductive hole 11 make button show uniform light to placing key-press, and first lamp position hole 12 is sent out to accommodate
LED on optical assembly 4.Preferably, one end arrangement of first lamp position hole 12 along photomask 1 is set, the light-conductive hole
11 arrange at the middle part of photomask 1 is set.The diaphragm 2 is transparent, is covered in the front surface A of photomask 1, the diaphragm
The first flanging 21 and the second flanging 22 are formed on 2.Preferably, the diaphragm 2 is PET protection film, has in light weight, intensity
Height, the transparency and gas barrier property it is good, it is nontoxic, it is tasteless the advantages that.The light guiding film 3 is pasted onto the back surface B of the photomask 1, is formed
Region between the flanging 22 of the first flanging 21 and second, corresponding second lamp position hole 31 is offered in the light guiding film 3
Luminescence component 4 is avoided during assembling, the flanging 22 of the first flanging 21 and second is respectively facing the back surface B turnover of photomask 1, shape
Into seamless wrapping, can effectively solve leakage problem.
As in Figure 2-4, during assembling, the first step, first on the diaphragm 2 in advance punching two parallel dotted lines, dotted line into
Type method forms the first flanging 21 and the second flanging 22 similar to stamp hole process for stamping, the dotted line, then will be formed with first
The transparent protective film 2 of the flanging 22 of flanging 21 and second is covered in the front surface A of the photomask 1.Preferably, the diaphragm 2 is complete
All standing is in the front surface A of the photomask 1.Second step, one layer of light guiding film 3 is pasted in the back surface B of the photomask 1, it is described
The region that light guiding film 3 is formed between the flanging 22 of the first flanging 21 and second.3rd step, along the first flanging 21 towards screening
The back surface B of light film 1 is turned down, and the turnover of the diaphragm 2 drives the turnover of photomask 1, and the light guiding film 3 is coated on shading completely
The inside of film 1, first lamp position hole 12 are overlapping with the second lamp position hole 31.4th step, luminescence component 4 is assembled in photomask 1
In back surface B, corresponding first lamp position hole 12 of the LED of luminescence component 4 and the second lamp position hole 31, further along the second flanging 22 towards screening
The back surface B of light film 1 turns down, and the turnover of the diaphragm 2 drives the turnover of photomask 1 to carry out seamless wrapping, completes key-press backlight
Assembling.Finally, then by above-mentioned key-press backlight component it is assembled to the relevant position of display device.By the way that the both sides of photomask 1 are turned over
Folding carries out seamless wrapping to luminescence component 4, effectively solves the problems, such as key-press backlight component light leak and improves production efficiency.
It is that dead color is either light tone or one that the front surface A and back surface B of photomask 1 described in the utility model, which can be,
Face light tone one side is dark-coloured, it is preferable that the dead color is black, and the light tone is white.Using the photomask 1 of light tone due to seamless
Light leak will not be caused after bound edge, also helps lifting brightness., can be with although luminance-reduction can be made using the photomask 1 of dead color
The problem of using its extinction function treatment brightness unevenness.
It should be appreciated that the flanging in the utility model is not limited to two, in actual applications, portioned product is only required
One side light leakage, then needing one side of light leakage that flanging is set.
It is last it should be noted that above example is only illustrating the technical scheme of the embodiment of the present invention rather than it is entered
Row limitation, although the embodiment of the present invention is described in detail with reference to preferred embodiment, one of ordinary skill in the art
It should be understood that can still be modified to the technical scheme of the embodiment of the present invention or equivalent substitution, and these modifications or wait
The scope of amended technical scheme disengaging technical scheme of the embodiment of the present invention can not also be made with replacement.
