Description:

Reflective LCDs often use an uneven reflective layer (micro-reflective structure, MRS) to enhance diffuse reflection and thus improve the viewing angle. In order to more effectively design the MRS structure of the reflective layer, we have developed an optical simulation method that can be used for viewing angle simulation and reflectivity simulation of reflective LCDs. Through this simulation method, the MRS design can be optimized more easily, and the best design parameters can be obtained. The optimized design of MRS can effectively improve the viewing angle of the reflective LCD, wherein the oblique incident light is reflected into the viewing area close to the vertical direction, and the distribution of left and right brightness viewing angles becomes more symmetrical.
