High luminance hybrid light guide plate for backlight module application.

Enhancing BEF Luminance for TFT-LCD Industries using the Hybrid Approach of Prediction and Optimization Techniques

A Backlight Module is the main source supply of liquid crystal display components. Its power consumption is about half the liquid crystal display. Among the Backlight Module, BEF / DBEF enhances luminance 50% to 100%. Therefore BEF (Brightness Enhancement Film) / DBEF (Dual Brightness Enhancement Film) becomes the main critical component of Backlight Module. The assurance of sustaining balance ...

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

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...

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...

Enhancing LCD Optical Efficiency with a Linearly Polarized Backlight and Polarization-preserving Light Guide Plate

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 en...
