Description
Technical field
The present invention relates to a kind of polymerisable compound and the said composition purposes on the preparation blooming.
Background technology
Liquid-crystal display (Liquid Crystal Display, LCD), have frivolous, short and small, thermal value is low, current consumption is low and advantage such as almost radiationless, progressively replaces conventional cathode ray tube (CathodeRay Tube, CRT) indicating meter at present.
At present, in backlight module, utilize blooming miscellaneous to improve the panel briliancy, become most economical easy product development scheme, mode not only must not changed any component design according to this, also must not consume additional energy source, and can improve the LCD panel luminance and make light source do the performance of full blast.
Brightness enhancement film is called for short BEF (Brightness Enhancement Film) usually or claims condensing film, is on polyester base material, is coated with special acryl resin coating, and then utilizes high-energy ultraviolet ray (UV) that it is hardened into prism microstructure and make.The main function of brightness enhancement film is by the effect of refraction with inner full-reflection, will collect and be concentrated to positive visual angle (On-Axis) direction of degree approximately ± 35 by the ghost line that light guiding plate (Light Guide) is issued to from all directions, to improve the briliancy of LCD.
General brightness enhancement film commonly used is to utilize the linear prism columnar structure to reach spotlight effect, yet, the refracted ray that brightness enhancement film produced that generally contains the linear prism columnar structure, easily with from other diaphragm-operated in the indicating meter reflect or refracted ray, or other reflection or the refracted ray of brightness enhancement film itself, produce the optical interference phenomenon, cause occurring in appearance phenomenons such as moire (moire) or Newton's rings.For this reason, United States Patent (USP) the 6th, 280, No. 063 a kind of brightness enhancement film of exposure with circular arc columnar structure, it can further integrate light harvesting and diffusion, reaches light harvesting and even light purpose, and can avoid the optical interference phenomenon.In addition, the brightness enhancement film of arc columnar structure also can reduce simultaneously between prism structure and other diaphragm or the panel contacting the scratch that is produced, the increase wear resistance.But the brightness enhancement film of arc columnar structure can reduce briliancy, and for remedying the loss of briliancy, generally improvement method is to select the polymeric coating of high index for use.Generally speaking, the specific refractory power of polymeric coating is high more, and the brightening effect of brightness enhancement film is good more, and for example Japanese Patent 5-127159 discloses.
