Abstract
The utility model provides a light guide structure of a cell phone touch screen character area, and the light guide structure is disposed under a cell phone touch screen character area. The light guide structure comprises a light guide plate and light guide columns, wherein the light guide plate is made from transparent rubber, and the light guide columns are arranged on the light guide plate and enables LED light on a cell phone circuit to be transmitted onto the panel of the light guide plate. Light guide points are arranged right under the cell phone touch screen character area on the panel of the light guide plate and are used for enhancing the luminescence intensity of the right side of light. According to the light guide structure of a cell phone touch screen character area, the light guide efficiency is effectively improved and the assembly operation for a cell phone is simple.
Description
Technical field
The utility model relates to the mobile phone technique field, relates in particular to a kind of handset touch panel character zone light guide structure.
Background technology
The leaded light mode of handset touch panel character zone is provided with press key lamp usually on mainboard, realize the character zone printing opacity through following dual mode:
A kind of mode is directly below button, to arrange several lamps uniformly, and the quantity of lamp and position are confirmed according to key position and size.There are three shortcomings in this mode: 1) quantity of lamp wants many, can cause cost than higher and relatively power consumption like this.2) button light can be very uneven.3) owing between the LED lamp on touch-screen and the mainboard, also be separated with LCD screen, therefore often lamp can not be in character zone under, light guide effect is poor.
A kind of in addition mode is placed light guiding film exactly on press key lamp.The light guide effect of this mode makes moderate progress for relative first kind, but effect still can not be satisfactory.Its shortcoming is, light guiding film thickness generally has only 0.1mm ~ 0.15mm, and leaded light intensity is low, if increase miscellaneous part such as reflectance coating again, will cause assembling complicated, and cost is high.Character zone distance L ED lamp still is distant simultaneously, and the light that the LED lamp shows still is not very bright.
The utility model content
For this reason, the utility model technical problem to be solved is: a kind of handset touch panel character zone light guide structure is provided, and it is good effectively to improve light guide effect.
So; The utility model provides a kind of handset touch panel character zone light guide structure; It is arranged on handset touch panel character zone bottom; Comprise: the LGP that transparent rubber is processed can be delivered to the LED light on the circuit board of mobile phone leaded light post on the LGP panel with being arranged on the LGP, also is provided with the leaded light point that is used to strengthen light positive face luminous intensity on the LGP panel under the mobile phone characters by touch screen zone.
Wherein, said leaded light post is apart from the LED lamp 0.5mm on the circuit board of mobile phone.
Said leaded light post is 2.
Said leaded light post and LGP are structure as a whole.
Said LGP plate thickness is 0.3mm.
The said handset touch panel character zone of the utility model light guide structure; Through the LGP that one transparent rubber is processed being set in handset touch panel character zone bottom; And can the LED light on the circuit board of mobile phone be delivered to the leaded light post on the LGP panel and under the mobile phone characters by touch screen zone refraction strengthening membrane be set on the LGP panel in setting on the LGP; Make the LED light on the circuit board of mobile phone evenly be transmitted to handset touch panel character zone below; Leaded light efficient effectively improves, and the mobile phone assembling procedure is simple.
Description of drawings
Fig. 1 is for using the handset structure sketch map of the said handset touch panel character zone of present embodiment light guide structure;
Fig. 2 is a mobile phone structure sketch map shown in Figure 1;
Fig. 3 is the said handset touch panel character zone of a present embodiment light guide structure vertical view;
Fig. 4 is a handset touch panel character zone light guide structure end view shown in Figure 3.
Embodiment
Below, in conjunction with accompanying drawing the utility model is described in detail.
To shown in Figure 4, present embodiment provides a kind of handset touch panel character zone light guide structure 20 like Fig. 1, and it is arranged on handset touch panel character zone 10 bottoms, and this light guide structure 20 comprises: LGP 21 and leaded light post 22.
Wherein, LGP 21 has transparent rubber to process, and concrete is processed by 90% transparent plastic.Leaded light post 22 is arranged on the LGP 21, and leaded light post 22 can be delivered to the LED light on the circuit board of mobile phone on LGP 21 panels.Simultaneously, also be provided with the leaded light point 23 that is used to strengthen light positive face luminous intensity under the mobile phone characters by touch screen zone 10 on LGP 21 panels.
Leaded light post 22 can be structure as a whole with LGP 21.The thickness of LGP 21 is generally 0.3mm, make leaded light efficient with respect to have only 0.1mm ~ light guiding film of 0.15mm thickness improved 5 ~ 10 times, and can injection moulding production, make simple.
Leaded light post 22 generally has only 0.5mm apart from the LED lamp on the circuit board of mobile phone (not indicating among the figure), and this makes the more common light guiding film of leaded light efficient can improve 20 times.
The handset touch panel character zone light guide structure 20 that present embodiment provides only needs to get final product for the characters by touch screen zone provides two LED lamps on the circuit board of mobile phone, need described in the background technology need not four LED lamps.Simultaneously, on touch-screen, the LED lamp is installed on the pcb board by SMT factory paster LGP by touch-screen supplier assembling on provided parts.During final mobile phone manufacturer factory-assembled, only need touch-screen is installed on the fore shell and get final product, need not to add other operations, assembly relation is simple.
In sum; The said handset touch panel character zone of present embodiment light guide structure; Through the LGP that one transparent rubber is processed being set in handset touch panel character zone bottom; And can the LED light on the circuit board of mobile phone be delivered to the leaded light post on the LGP panel and under the mobile phone characters by touch screen zone refraction strengthening membrane be set on the LGP panel in setting on the LGP; Make the LED light on the circuit board of mobile phone evenly be transmitted to handset touch panel character zone below, leaded light efficient effectively improves, and the mobile phone assembling procedure is simple.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection range of the utility model.
