High luminance hybrid light guide plate for backlight module application

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-...

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...

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

Light-guide plates (LGPs) with aperiodic or size-varied microstructures are widely used in edge-lit light-source backlight systems for their high uniformity. In this Letter we designed a LGP with periodic and single-sized microstructures and analyzed the relationship between the holistic arrangement density of the microstructures and the uniformity. By controlling the holistic arrangement densi...

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 ...
