Abstract

The LGP(Light Guide Panel) for the back light unit that is used to the 2.2" TFT LCD was designed and fabricated. The method of the pattern design which is the most important in the design of the LGP was converted the V-cutting method into the Dot method. This newly developed Dot method provided a good uniformity in the brightness at the LGP, which was a very difficult problem to solove in the V-cutting method. The experiment result of the newly designed LGP shows the brightness uniformity 90% and the brightness 3656 $cd/\;m^2$ which is 20% higher than the commercial products.
