Description
Technical field
The utility model relates to mobile phone screen technical field, is specially a kind of cell phone back tabula rasa comprising improvement flexible circuit board structure.
Background technology
Current mobile phone market progressively tends to not only thin but also light product, so backlight module is also thereupon toward this future development, the embodiment of slimming is mainly the thickness of light guide plate, but the light sources of backlight is LED, the thickness of current LED divides two kinds, 0.4mm and 0.6mm, does not have other sizes, and the brightness of 0.6mm is higher, so most backlight factory can use the LED of 0.6mm.LED itself can not be assembled in separately in backlight, will be combined be energized with flexible PCB, makes it to reach luminous.The light guide plate that market uses is almost about 0.5mm to 0.3mm thickness, light guide plate and FPCB in conjunction with time (as Fig. 1) due to the wedge configuration of light guide plate, even if flexible PCB is pasted onto in light guide plate, after certain hour degree of sticking together declines, be easy to tilt, and the reason tilted is due to after the wedge configuration of light guide plate can make anti-dazzling screen be stained with flexible PCB, there is the effect of individual Hui Li, flexible PCB is tilted, cause between flexible PCB and light guide plate, forming light leak gap (as Fig. 2), therefore flexible PCB LED holds tilting can cause the direct directive light-emitting zone of light, lamp source fore-end there will be the phenomenon (as Fig. 3) of quick-fried lamp.
But a kind of comprising improves the cell phone back tabula rasa of flexible circuit board structure there is not been reported.
Utility model content
The purpose of this utility model is to overcome prior art deficiency, and provides a kind of cell phone back tabula rasa comprising improvement flexible circuit board structure.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of cell phone back tabula rasa comprising improvement flexible circuit board structure, backlight comprises: LED light source, anti-dazzling screen, the lustre adding layer be formed by stacking by upper and lower brightening piece and diffusion sheet, light guide plate, reflector plate, glue chase, and described light guide plate light inputting end is that wedge-shaped projection correspondence is provided with LED light source;
LED light source top is connected with flexible PCB 1, and LED light source and wedge-shaped projection cover by this flexible PCB 1;
Flexible PCB 1 top is provided with anti-dazzling screen, and bottom is provided with light guide plate;
Flexible PCB is pasted with the wedge-shaped projection of light guide plate and is connected;
Flexible PCB upper front end is adhesive with transparent mulch film, and this transparent mulch film and wedge-shaped projection are symmetrical arranged.
The beneficial effects of the utility model:
1, the utility model there will not be quick-fried lamp phenomenon.
2, the utility model production and processing is easy, and any one new person can operate, very convenient.Simultaneously cost-saving, save time.
3, the utility model design is ingenious, novel, uses very effective in mobile phone backlight screen.
