Devices and methods for reducing power consumption of a demultiplexer

An electronic display comprising:

• a demultiplexer comprising a first transistor, a second transistor, and a third transistor;
• a first switch coupled between a first gate of the first transistor and a second gate of the second transistor, the first switch being configured to selectively connect the first gate to the second gate;
