Abstract

The new driving method and circuit are proposed for a low cost local dimming Xe backlight unit. The basic concept of the proposed driving method is that the subsequent discharge can be produced easily under the low voltage condition thanks to the wall charges induced by the previous discharge. Therefore, this driving method can drive the 40-in. backlight with 64 local dimming blocks by using only four transformers.
