Abstract

This paper presents two LED backlight driving techniques, (1)Vcc similar to GND circuit, (2)Vcc similar to GND similar to Vss Schmitt Trigger circuit to adjust the duty cycle of its LED signals. The first proposed circuit contributes to lower the power consumption by generating PWM driving signal for LEDs, the second proposed circuit discharges the LEDs to reduce the heat effect of LED driving.
