Abstract
A display system and a method for forming an output buffer of a source driver are provided. The display system includes a plurality of pixels coupled to a plurality of gate lines and a plurality of source lines. A gate driver provides a plurality of gate signals to the plurality of gate lines. A source driver provides a plurality of image signals to the plurality of source lines. The source driver includes an output buffer. The output buffer includes a transistor. The transistor is either a native transistor device, a depletion-mode transistor device or a low-threshold transistor device.
