Abstract: A compact light guide plate (LGP) with special designed microstructures and dual collimated light sources was proposed to achieve an adjustable riming angle backlight for eco-display. The micro-prisms were utilized to guide the emitting rays toward normal viewing cones while a set of strip patterned diffuser toward wide viewing cones. The uniformity of spatial luminous can reach 91% / 87% at view cone of ±3/±60 deg. in each mode. Only 5% of power consumption in narrow viewing angle mode was needed to keep the same luminance in wide viewing angle mode.
