Technical field
It is specifically a kind of to be used for ADS type composite light guide plate the present invention relates to field of new materials.
Background technique
So-called backlight panel is a kind of light source positioned at liquid crystal display behind, its illumination effect will directly influence liquid
Brilliant display module visual effect.Liquid crystal itself does not shine, it shows figure or character is its result to light modulation.With
The continuous development of LCD technology, the application field of liquid crystal display especially colour liquid crystal display device are also constantly being widened.
The quality of backlight performance is other than it will have a direct impact on LCD imaging quality, and the cost of backlight accounts for the 30-50% of LCD module, institute
The electric power of consumption more accounts for the 75% of module, can say it is considerable spare part in LCD module.
Light guide plate is acrylic/PC plate material using optical grade, and then using has high reflectivity and the not high-tech of extinction
Skill material is the core of backlight panel, and the site of light guide plate is broadly divided into printing-type: after light guide plate completes sharp processing,
Site is imprinted on reflecting surface with mode of printing；Non-printing formula: by site light guide plate shape when direct forming in reflecting surface；Mainly
Method (V-cut), photolithography (Stamper), the internal method spread are portrayed for precision machinery.
Since the technique of non-printing formula site requires high, cost height；So existing popular style display screen majority uses
Printing-type technique.But for the backlight panel of ADS type, since its structure narrows partially, the dot surface of light guide plate and anti-
The contact amplitude for penetrating piece is very big, and dot surface is caused to there is abrasion risk, so after prolonged use, often result in light guide plate
Light quality decline.
