Liquid crystal display having driving circuit for light emitting device |
摘要 |
A backlight module that uniformly maintains the brightness of a light emitting device, in which the number of transformers is reduced, and that is applicable for use with large cold cathode ray tubes includes cold cathode ray tubes arranged in parallel, transformers having first secondary-side terminals connected to first electrodes of the cold cathode ray tubes and whose primary side terminals are connected in series to constitute a closed loop, a first inverter circuit that applies a first sine wave voltage to second terminals on the secondary sides of the transformers, and a second inverter circuit that applies a second sine wave voltage having opposite phase to second electrodes of the cold cathode ray tubes.
