Transmissive liquid-crystal display (LCD) devices are being extensively used for man-machine interfaces. Each LCD possesses a backlight unit (BLU) which is an indispensable device for a LCD. In early stages of LCD emerging period (1985-1995), lack of light ray control and optical design concept were the main issues of BLUs. Based on the total internal reflection (TIR) and nearly frustrated TIR, the author eveloped micro-reflector (MR) and micro-deflector (MD) for light control media, i.e., light-guide plate (LGP) and optical cavity, to build-up an optical concept for BLU design. The BLU issues were solved and the luminance on the BLU increased by 70% and resulted in saving power consumption of the LCDs. In the meantime, MRs or MDs were patterned on metal sheets and novel fabrication process was developed to accelerate the mass productions of the LGPs by 8 to 10 times.
