Abstract

It is easy for the liquid crystal to save the electric power for non-emissive display essentially in various flat panel displays, and to improve the electro-optical property by function separation of a light source and an optical control, etc. However, the utilizing efficiency of light in liquid crystal displays is about several %. One of the low efficiency factors is a color filter. We adopted the FS method to switch the light source color using OCB mode with excellent switching speed. This method is a technology that displays full colors by switching a red, green, blue image at high speed sequentially. The merit of this method is high efficiency without using the color filter that absorbs 67.1% of the backlight, and it is a useful skill to the power consumption reduction of the liquid crystal panel. In addition, there is an advantage that clear motion image can be displayed for this method to blink the source of the backlight at high speed. The 6-inch LCD panel with the FS OCB mode was manufactured. The clear motion image, high utilizing efficiency of light, and large color gamut were achieved.
