Definitions
- LCDs liquid crystal displays
- light diffusion plates for direct-type backlights mounted on TVs that require brightness are mainly made of acrylic resin for screen sizes of about 20 inches.
- acrylic resin has low heat resistance and high hygroscopicity, so it is inferior in dimensional stability.
- a large screen size has a problem that warpage deformation occurs. Therefore, recently, polycarbonate resin, which is superior to acrylic resin in heat resistance and hygroscopicity, has been used as a matrix resin for a light diffusion plate, and the demand thereof has been increasing.
- polycarbonate resin is used as the transparent resin for the matrix, the resin has superior heat resistance, impact strength and moisture absorption compared to acrylic resin.
- Polycarbonate resin itself is transparent. It is inferior to acrylic resin in that it has a disadvantage that when a light diffusing agent is added, the diffused light obtained as a result of light diffusion has a yellow color tone and a reduced brightness.
