Light-guide plate using periodical and single-sized microstructures to create a uniform backlight system.

High luminance hybrid light guide plate for backlight module application.

We introduce a hybrid backlight module, which consists of a hybrid light guide plate (HLGP) and a brightness enhancement film (BEF). The HLGP comprises functions of a conventional light guide plate, a reflector, and a BEF. The HLGP allows one-dimensional rays to be collimated. We add a BEF above the HLGP, and let the crossed-dimension rays to be collimated. Comparing with the conventional edge-...

Viewing Angle Switchable Display with a Compact and Directional Backlight Module

A compact light guide plate (LGP) with special designed microstructures and dual collimated light sources was proposed to achieve an adjustable viewing 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 v...

Design and Fabrication of Light Guide Plate Application in LED BackLight Module

Design of Integrated Light Guiding Plates Using Silicon-based Micro-Features

This study addresses the design of an integrated light guide plate (LGP) to produce a uniform illumination with enhanced axial luminous intensity without use of prism sheets and diffusive sheets. The LGP design applies the micron-sized features fabricated from a novel stamper process that combines anisotropic wet etching of silicon-oninsulator (SOI) wafers with electroforming to fabricate and d...

Integrated process capability analysis with an application in backlight module

Backlight application specializes in supplying light, with notable examples including liquid crystal display (LCD), hand-phone LCD, and PDA LCD. The integrated process capability and integrated process yield for cold cathode fluorescent lamp backlight are unknown. Process capability analysis is a highly effective means of assessing the process ability of backlight that meets specifications. A l...
