| This optical "colorant-free" color filter is based on a sub-micron scale wire grid polarizer, and another dielectric material formed on a substrate. The object is to provide polarization light and high transmission of color without using pigment.
The wire grid polarizer only allows light waves of a certain rotation to pass through. The arrangement and incident angles are finely tuned - the ideal polarizer blocks one polarization light and passes another polarization through freely.
Another object of this invention is to provide a polarizer matrix between color filter cells, which has a similar surface structure but different dimensional parameters. The intensity of the light arriving at the output of the display device is higher, resulting in a better image quality. |
