Description
Technical field
This utility model relates to the technical field of display device, refers more particularly to a kind of backlight module and mobile terminal.
Background technology
At present in mobile phone industry low-end item, the most all using TFT liquid crystal display screen, the full attaching process of GFF, purpose is exactly
Reduction cost.It is well known that, liquid crystal display screen luminous source is backlight module LED (typically having 12 or 14), LED to
Launch light from all directions, through white size frame and gap, thus cause glue frame outer surface to give out very high light line.As Fig. 1 shows
Shown in being intended to.
When complete machine is white, TP Lens, face-piece and battery cover are all that white just meets ID requirement.And when TP lens is
During white, put glue glue between TP and face-piece and can only use transparent glue or the Lycoperdon polymorphum Vitt glue with Photoresist, and both
Glue all can not stop the light that liquid crystal display screen dissipates effectively.Then complete machine in terms of front, finds complete machine side light leak.
But white size frame improved and solves light leak, bothering the most very much.Have to be white near internal glue frame,
From screen, otherwise arise that screen surrounding shadow.In order to improve and solve light leak, structural engineer has thought a lot of scheme,
What current whole industry was more feasible has two schemes.The first scheme: glue frame is carried out double-shot moulding, its outer surface is black
Color, inner surface is white, and such light cannot appear from glue frame.As it is shown in figure 1, the structure of glue frame 1 uses half to be black
Color half is the structure of white.
First scheme: in glue frame side bag black PET (thickness 0.05mm), stops light to spill.But the program has
A lot of shortcomings: 1. needing a large amount of manpowers to carry out bag black PET, human cost is higher；2. very limited due to the thickness of liquid crystal display screen own,
The effective bonding area of black PET is very limited, thus causes adherence force the least, and the time one, long being easy to tilted, and was assembled into whole
In machine, light leakage phenomena occurs again；3. bag black PET is artificial realization, thus causes comparison of coherence poor, and product stability drops
Low.So bag black PET is very labor intensive, material, cost.
