Abstract

Demands for personal digital assistants (PDA) require them to be of low profile, lightweight, and to have low power consumption. To fulfill these demands, it is necessary to develop a backlight unit that has features of low power consumption, high brightness, and high efficiency. The light source in a backlight unit has a light-guide plate with microreflection dots, which is a very important component. The smaller the microreflection dots and the higher the aspect ratio, the brighter the screen. The result of a simulation revealed that it is possible to improve the brightness of the light-guide plate by forming the shape of a truncated cone with a taper angle range of 68 to 78 degrees. However, by using the existing machining technology, it is difficult to form the microreflection dots into such a shape. Thus, we developed an innovative UV diffraction exposure method to fabricate tapered microstructure. We fabricated a light-guide plate using the UV-LIGA process by the UV diffraction exposure.
