Integrated Touch Sensitive Display Gate Driver
First Claim
1. A circuit comprising:
- a switch configured to switch a gate line of an integrated touch sensitive display between a first configuration and a second configuration, the first configuration switchably connecting the gate line to a voltage supply from display circuitry and the second configuration switchably connecting the gate line to another voltage supply from touch circuitry.

Abstract
A gate driver circuit for switching gate line voltage supplies between display and touch modes is disclosed. The circuit can include one or more switches configured to switch one or more gate lines of an integrated touch sensitive display between a display mode and a touch mode. During touch mode, the circuit can be configured to switch the gate lines to connect to a more stable voltage supply. The circuit can also be configured to reduce or eliminate interference from the display circuitry to the touch circuitry that could affect touch sensing. During display mode, the circuit can be configured to switch the gate lines to connect to a fluctuating voltage supply.
