Systems, apparatuses, and methods for performing mid-frame blanking. A first portion of a frame is driven to a display and then a first mid-frame blanking interval is generated. Following this first mid-frame blanking interval, a second portion of the frame is driven to the display, followed by a second mid-frame blanking interval, followed by a third portion of the frame, and so on. Any number of mid-frame blanking intervals may be introduced in a given frame. During each mid-frame blanking interval, touch sensing is performed to detect touch events on the screen for in-cell touch type displays. For displays with touch sensors electrically separated from the display common voltage layer, special sense scan steps are performed during mid-frame blanking intervals. By performing touch sensing or special sense scan steps during a frame rather than only at the end of a frame, the performance of touch sensing is improved. |
