Enhancing LCD Optical Efficiency with a Linearly Polarized Backlight and Polarization-preserving Light Guide Plate
نویسندگان
چکیده
We propose a new polarization-preserving edge-lit light guide plate (LGP) based on total internal reflection. Our simulation results show that such a LGP exhibits several attractive features: 1.54X higher polarization efficiency, 2.4X higher on-axis luminance, and no need for a brightness enhancement film. When integrated with a linearly polarized LED array, the LCD optical efficiency can be enhanced dramatically and its power consumption can meet the challenging goal set by Energy Star 6.

Design and fabrication of an integrated polarized light guide for liquid-crystal-display illumination.
An integrated polarized light guide was designed and fabricated for use as a liquid-crystal backlight with emphasis on uniformity of the light and conversion of p-polarized to s-polarized light. Two different micro-optical structures were fabricated both on the top and the bottom surfaces of the light guide. On the top surface, a subwavelength grating separates s-polarized and p-polarized light...

A novel polarization converter using reflective metallic gratings and a polarization beam splitter is introduced for LCD backlight illumination. These two optical elements form a polarization rotation resonator. Broadband and high optical efficiency of polarization conversion in the visible region is achieved through the resonance of the refracted light and the surface plasmon wave in metallic ...

Yan Li (SID Student Member) Thomas X. Wu (SID Member) Shin-Tson Wu (SID Fellow) Abstract — A high-performance reflective polarization converter which could be used in a backlight recycling system for liquid-crystal-display (LCD) devices is proposed. The device consists of a twistednematic (TN) liquid-crystal film, a uniaxial A-plate, and a reflector. The configuration parameters, such as thickn...
متن کاملGeneration of Radially Polarized Beam for Laser Micromachining
A novel means of generating radially polarized light is reported in this paper. A birefringent plate was placed in a divergent or divergent portion of the laser beam for polarisation conversation. The influence of birefringent plate thickness on the purity and efficiency of radial beam conversion is studied qualitatively. This technique is robust, simple and cost effective for radial polarisati...
متن کاملPolarized backlight based on selective total internal reflection at microgrooves.
A polarized backlight for LCD illumination is designed and fabricated in which s-polarized light is extracted owing to selective total internal reflection at microstructures in the anisotropic layer. From the measurement, the contrast ratio in normal viewing direction can be as high as 64. Luminous uniformity of higher than 80% is achieved for polarized backlights. Furthermore, 1.6 gain in effi...
