“…A traditional LCD has a panel unit with liquid crystals disposed between two glass substrates and a backlight module unit to generate light. The backlight module unit can use many types of light sources: LED, external electrode fluorescent lamp, cold cathode fluorescent lamp, and flat fluorescent lamp evenly distributed at the periphery of the backside of an LCD panel. The traditional backlight module unit installs fluorescent lamps at the edge of the backlight or a direct type of an LCD panel to produce backlight by a linear light source.…”

An approach to optical plate production using the nanomorphology of polymer blends in lightscattering thermosetting plates based on self-assembly was investigated without using the conventional approach of blending nanoparticles such as silica sol, zirconia sol, phosphor, or chromophore into the polymer matrix. For this purpose, two specified polymers having carboxylic acid and epoxy groups were blended using a light-emitting diode for use in liquid crystal displays. The developed light-scattering thermosetting plate containing poly(acrylic acid) with the carboxylic acid at four different weight average molecular weights in a cycloaliphatic epoxy polymer was shown to achieve regular nanoparticles of 30-350 nm for light-scattering, light-scattering rates of over 10% at a wavelength of 300 nm, a thermal stability up to 230 8C, O 2 gas barrier properties approximately 50 times smaller than that of polyethylene, and solvent resistance after polymerizing.
