Abstract: A gate signal adjustment circuit for a display is disclosed. The gate signal adjustment circuit can adjust a transition time of a gate signal used to drive data displaying. The adjustment can be to either speed up or slow down the transition time according to the requirements of the display. In an example, the gate signal adjustment circuit can include multiple transistors, where a first set of the transistors outputs the gate signal and a second set of the transistors outputs an adjustment to the gate signal. The second set of transistors can be the same or different sizes depending on the desirable number of adjustment options. The circuit can also include a control line coupled to the second set of transistors to control the adjustment output. Gate signal adjustment can reduce crosstalk in the display.
