LED Packaging technology for LCD Backlight
Application
Abstract:
This presentation reviews
current status on LED packaging technology used in LCD backlight module (BLM)
design. Great efforts have been invested into this application for last 3-4
years. Our study has proven the feasibility of using an array of LEDs for
the application of liquid crystal display (LCD) backlight. There are several
technologies competing in this market with the following key driving
factors: Cost of LEDs, Efficiency of the LED BLM designs, and Performance.
Although many promising results were achieved with standard off-the-shelf
LEDs, significant improvements in surface radiance uniformity and efficiency
could be obtained with different light guide designs and packaging
technologies. With the continuing cost reduction on CCFL technology, Can LED
technology make a wave in this challenge? We will discuss the performance of
display BLM using LED approaches in terms of cost, performance,
and scalability in the Monitor and LCD-TV applications.
