New X-Y Channel Drive Method for LED Backlight System in LCD TVs

摘要：

This paper proposes a novel RGB-LED (light emitting diode) backlight system, for 32 LCD TVs, accompanied by a new X-Y Channel drive method in which its row and column converters control the individual division screen. This proposed driving method is able to produce division drive effects such as image improvement and reduced power consumption. Not only that, the number of converters needed in this method, that is 4 × (m +n) , is much fewer than that of cluster drive method, that is 4 × (m × n).
