Circuit and method for sensing open-circuit lamp of a backlight unit and display device with circuit for sensing open-circuit lamp of backlight unit
Abstract:
A circuit for sensing an open-circuit lamp is provided. The circuit includes a reference voltage output unit, a voltage sensor, and a comparator. The reference voltage output unit provides a reference voltage. The voltage sensor detects a sensed voltage corresponding to a status of a lamp. The status of the lamp includes an open-circuit status and a closed-circuit status. The comparator compares the sensed voltage with the reference voltage and outputs a result indicating the status of the lamp.
Abstract(Chinese):
