Abstract
The utility model discloses a light guide plate module used on a keyboard of an electronic product, comprising a light guide plate, a rubber layer and a metal film layer, wherein the bottom surface of the light guide plate is attached on the top surface of the rubber layer, and the bottom surface of the rubber layer is attached on the metal film layer. The light guide plate module is characterized by comprising a light sealing ink layer which is covered on the side surface of the light guide plate. According to the light guide plate module, the light sealing ink layer is additionally arranged so as to cover the side surface of the light guide plate, so that the light can be prevented from leaking from the side edge of the light guide plate, and further the good light sealing effect is achieved.
Description
Technical field
The utility model relates to the electronic product accessory, relates in particular to a kind of light guide plate module that is used for the keyboard of electronic product.
Background technology
Along with development of science and technology, the frequency that electronic product occurs in people's life is more and more higher, even has become an indispensable part in people's life.In general, the inboard of electronic product (for example mobile phone, PDA, MP3 or MP4 etc.) button often is equiped with light source illuminating button, so that the user still can find sign on the button when using at the dark place with correct selection key.At present, a kind of light source is to illuminate in the some LED lamp of button installed inside, yet this to illuminate the mode structure comparatively complicated, and distribution of light is inhomogeneous, and is brighter from the zone that the LED lamp is near, and darker from LED lamp zone far away, is unfavorable for using.Another kind of light source is in the back side of button installing one deck light guide base plate, is equiped with the LED lamp at an end of light guide base plate.The LED lamp is luminous, guides to the button back side by light guide base plate and illuminates, thereby solved the uneven problem of distribution of light to a certain extent.Yet, when being installed on the button back side, existing light guide base plate its edge section is not sealed light, after the light of light guide plate section is dispersed out, come out by the button slit source easily, and reduce the utilization factor of light and influenced the outward appearance of product.
Therefore, urgent need is a kind of has the light guide plate module of good envelope light effect to address the aforementioned drawbacks.
The utility model content
The purpose of this utility model is to provide a kind of light guide plate module with good envelope light effect.
The utility model provides a kind of light guide plate module for achieving the above object, it comprises light guide plate, glue-line and metal film layer, the bottom surface of described light guide plate fits on the end face of described glue-line, the bottom surface of described glue-line fits on the described metal film layer, described light guide plate module also comprises envelope light ink lay, and described envelope light ink lay is covered on the side of described light guide plate.
The utility model is compared with prior art, because the utility model light guide plate module set up envelope light ink lay and cover the light guide plate side, thereby avoids light to spill from the edge of light guide plate, reaches good envelope light effect.
Preferably, the height offset appears in the side of described light guide plate and the side of described glue-line, and described envelope light ink lay extends to the edge of the end face of described glue-line from the edge bending of the end face of described light guide plate.
Preferably, the edge of described light guide plate forms two breach, is fitted with light-shielding sheet on the described breach.

Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
Fig. 1 has showed an embodiment of the utility model light guide plate module.Fig. 2 has then showed the cross-section structure of this embodiment light guide plate module.Fig. 3 to Fig. 6 is the concrete structure of various piece in the light guide plate module among this embodiment.With reference to above-mentioned each figure, below the light guide plate module of this embodiment is described in detail.
Extremely shown in Figure 2 as Fig. 1, present embodiment light guide plate module 10 is applicable to cell phone keyboard, this light guide plate module 10 comprises light guide plate 11, glue-line 12, metal film layer 13 and envelope light ink lay 14, the bottom surface of described light guide plate 11 fits on the end face of described glue-line 12, the bottom surface of described glue-line 12 fits on the described metal film layer 13, and described envelope light ink lay 14 is covered in the side 11a of described light guide plate 11.Particularly, to shown in Figure 6, be formed with several zones of leaded light with leaded light point 11e as Fig. 3 on the described light guide plate 11, thereby can adjust the light in the cell phone keyboard, make light realize effects such as brightness height, good evenness; Described glue-line 12 is used for fixing described metal film layer 13 makes its accurate location; Described metal film layer 13 is used to fit to the printed circuit board (PCB) in the cell phone keyboard, is formed with several conduction buttons 13a on it, and described conduction button 13a is used for the circuit on the printed circuit board (PCB) is produced on-off action; Described envelope light ink lay 14 is printed onto dirty oil on described light guide plate 11 and the glue-line 12 by the silk-screen half tone and forms, and the side 11a of described light guide plate 11 is sealed light.
Particularly, as shown in Figure 2, among this embodiment, the height offset appears in the side 11a of described light guide plate 11 and the side 12a of described glue-line 12, described envelope light ink lay 14 extends to the edge of the end face 12b of described glue-line 12 from the edge bending of the end face 11b of described light guide plate 11, thereby covered the side 11a of described light guide plate 11 closedly, reached good envelope light effect.In addition, as shown in Figure 1, among this embodiment, the upper edge of described light guide plate 11 forms two breach 11c and 11d, is fitted with light- shielding sheet 15a and 15b respectively on described breach 11c and the 11d.Described light- shielding sheet 15a and 15b are used to cover the light that LED lamp position is upwards penetrated, and make light to parallel radiation, thereby improve the utilization factor of light.
The utility model is compared with prior art, because the utility model light guide plate module set up ink lay and cover the light guide plate side, thereby avoids light to spill from the edge of light guide plate, reaches good envelope light effect.In addition, the light guide plate on the utility model light guide plate module also is fitted with light-shielding sheet, has not only improved the utilization factor of light but also has made and the subsequent process steps minimizing improved production efficiency.
Above disclosed only is preferred embodiment of the present utility model, can not limit the interest field of the utility model certainly with this, and therefore the equivalent variations of being done according to the utility model claim still belongs to the scope that the utility model is contained.
