One of core part of display makes its lightweight, slimming, low energy consumption, height to keep it in the competitiveness of future market
Efficiency, high brightness become important research direction.
Backlight module can be divided into two kinds of straight-down negative and side entering type.Down straight aphototropism mode set is that light source is placed in liquid crystal display panel
Lower section, by forming uniform area source after the optical film assemblies such as diffusion barrier, brightness is high, and uniformity is good, but thickness is big.Side enters
Formula backlight module is that backlight is placed in light guide plate side, and the light that light source is sent out enters light guide plate from side i.e. incidence surface, warp
After crossing total reflection and the scattering of bottom surface site, projected from light-emitting surface, using forming area source after optical film assembly.Side entering type is carried on the back
Optical mode group thickness is small, is easy to lightening.

Its energy consumption is big, short life, structure rapid wear, colour gamut are small, simultaneously because the use of mercury brings the hidden danger of environmental problem.LED backlight
Strong, long lifespan of luminous efficiency height, energy conservation and environmental protection, color representation power etc., has already taken up a part of market, and be considered as
The main flow direction of LCD backlight future development.
With the progress of liquid crystal display manufacturing technology, people need to show area bigger, more frivolous, more aesthetically pleasing
Liquid crystal display product.Therefore, in order to promote visual effect, meets the needs of people, the narrow frame of liquid crystal display has become
Development trend.And core part one of of the backlight module as liquid crystal display, its narrow frameization is most important.
