Abstract
The invention discloses a light guide key module used for a keyboard of electronic products, the light guide key module comprises a light guide plate, a glue layer and a metal thin film layer, the bottom surface of the light guide plate is attached to the top surface of the glue layer, and the bottom surface of the glue layer is attached to the metal thin film layer. The light guide key module is characterized by further comprising a light tight ink layer covering a lateral surface of the light guide plate. The light guide key module disclosed by the invention is additionally provided with the light tight ink for covering the lateral surface of the light guide plate, thereby avoiding light leakage from an edge of the light guide plate and achieving good light tight effect.
Description
Technical field
The present invention relates to the electronic product accessory, relate in particular to a kind of light guide key module of the keyboard for electronic product.
Background technology
Along with the development of science and technology, the frequency that electronic product occurs in people's life is more and more higher, has even become an indispensable part in people's life.In general, the inboard of electronic product (such as mobile phone, LED, MP3 or MP4 etc.) button often is equiped with light source illuminating button, so that the user still can find sign on button with the selecting properly button when the dark place uses.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 the zone close to the LED lamp is brighter, and the zone away from the LED lamp is darker, 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 to a certain extent the inhomogeneous problem of distribution of light.Yet, when being installed on the button back side, existing light guide base plate its edge section is not sealed light, and after the light of light guide plate section is dispersed out, easily by the button slit source out, reduced the utilance of light and affected the outward appearance of product.
Therefore, urgent need is a kind of has the light guide key module of good envelope light effect to address the aforementioned drawbacks.
Summary of the invention
The object of the present invention is to provide a kind of light guide key module with good envelope light effect.
The invention provides for achieving the above object a kind of light guide key module, 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 height offset appears in the side of described light guide plate and the side of described glue-line, the bottom surface of described glue-line fits on described metal film layer, described light guide key module also comprises envelope ink layer, described envelope ink layer is covered on the side of described light guide plate, and described envelope ink layer 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.
Compared to the prior art the present invention because light guide key module of the present invention has been set up envelope ink layer and covered the light guide plate side, thereby avoids light to spill from the edge of light guide plate, reaches good envelope light effect; Simultaneously, the height offset appears in the side of light guide plate and the side of glue-line, and envelope ink layer extends to the edge of the end face of glue-line from the edge bending of the end face of light guide plate, thereby has covered the side of light guide plate closedly, enters a ground and reaches good envelope light effect.
Preferably, the edge of described light guide plate forms two breach, is fitted with light-shielding sheet on described breach.

Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in embodiment is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Based on the embodiment in the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
Fig. 1 has showed an embodiment of light guide key module of the present invention.Fig. 2 has showed the cross-section structure of this embodiment light guide key module.Fig. 3 to Fig. 6 is the concrete structure of various piece in the light guide key module in this embodiment.With reference to above-mentioned each figure, below the light guide key module of this embodiment is described in detail.
As extremely shown in Figure 2 in Fig. 1, the present embodiment light guide key module 10 is applicable to cell phone keyboard, this light guide key module 10 comprises light guide plate 11, glue-line 12, metal film layer 13 and envelope ink layer 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 described metal film layer 13, and described envelope ink layer 14 is covered in the side 11a of described light guide plate 11.Particularly, to shown in Figure 6, be formed with the leaded light zone 11e that several have light guiding points on described light guide plate 11, thereby the light in the capable of regulating cell phone keyboard makes light realize that brightness is high, the good evenness texts as Fig. 3; Described glue-line 12 is used for fixing described metal film layer 13 makes its accurate location; Described metal film layer 13 is used for fitting to the printed circuit board (PCB) in cell phone keyboard, is formed with several conduction buttons 13a on it, and described conduction button 13a is used for the circuit on printed circuit board (PCB) is produced on-off action; Described envelope ink layer 14 is printed onto dirty oil on described light guide plate 11 and 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, in 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 ink layer 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, in this embodiment, the upper edge of described light guide plate 11 forms two breach 11c and 11d, is fitted with respectively light-shielding sheet 15a and 15b on described breach 11c and 11d.Described light-shielding sheet 15a and 15b are the light that upwards penetrates be used to covering LED lamp position, make light to parallel radiation, thereby improve the utilance of light.
Compared to the prior art the present invention because light guide key module of the present invention has been set up ink lay and covered 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 light guide key module of the present invention also is fitted with light-shielding sheet, has not only improved the utilance of light but also makes subsequent process steps reduce, and has improved production efficiency.
Above disclosed is only the preferred embodiments of the present invention, certainly can not limit with this interest field of the present invention, and the equivalent variations of therefore doing according to the present patent application the scope of the claims still belongs to the scope that the present invention is contained.
