Document Type and Number:
WIPO Patent Application WO/2018/148998
Kind Code:
A1
Abstract:
Provided are a circuit and liquid crystal display device for reducing power consumption of a power supply. The circuit comprises: a transformer (T1), wherein a secondary drive winding (A) of the transformer (T1) has a first output end (3), a ground end (5), and a second output end (4) arranged between the first output end (3) and the ground end (5); and a first output loop (101) and a second output loop (102), wherein enabling one of the two loops and disabling the other is achieved by means of comparing a voltage outputted by the second output end (102) against a predetermined voltage.
