Abstract
A display may include an array of pixels that receive control signals from a chain of gate drivers. Each gate driver may include a number of semiconducting oxide transistors and capacitors. At least some of the semiconducting oxide transistors in the gate driver have bottom gate terminals configured to receive a separately adjustable bottom gate voltage for adjusting the threshold voltage during power on, normal, and power off operations. If desired, each gate driver may be provided with two or more different bottom gate voltages for individually controlling separate portions of the gate driver.
