Devices and methods for reducing power consumption and size of gate drivers
Abstract:
One gate driver includes an output node configured to be coupled to a gate line and to provide power to the gate line for driving thin-film transistor (TFT) gates of a display. An input node of the gate driver is configured to receive an input signal. The gate driver includes a first field-effect transistor (FET) having a gate, a drain, and a source. The drain may be coupled to the input node and the source may be coupled to the output node. The gate driver also includes a second FET having a gate, a drain, and a source. The drain may be coupled to the input node. The gate driver includes a capacitor having a first end coupled to the gates of the FETs and a second end coupled to the source of the second FET. Using the gate driver power consumption of the display may be reduced.
