Abstract: Various timing schemes can be used to synchronizing display functions with touch and/or stylus sensing functions for devices including a variable refresh rate (VRR) display. In a continuous-touch mode, for example, extended blanking can result in frame judder due to mismatch or latency between reporting of sensing data and the display. To minimize these issues, sensing operations can reset to re-synchronize with the display operation, and unreported data from sensing scans can be discarded or ignored. In some examples, a display frame can be divided into two sub-frames, and a system can be configured to perform a touch sensing scan during the first sub-frame of a display frame. At the conclusion of extended blanking, the sensing operations can reset to re-synchronize with the display. The touch sensing scan can be completed in one intra-frame pause and can begin at the start of the display frame.

Abstract: Setting a slew rate, e.g., a rising time or a falling time, of a scanning signal can be performed with a first operation, and a shunting resistance of the scanning line can be set with a second operation. A scanning system that scans a display screen, a touch screen, etc., can set a desired slew rate during a first period of time and can set a desired shunting resistance during a second period of time. A gate line system can sequentially scan gate lines to display an image during a display phase of a touch screen. The gate line system can, for example, increase the falling times of gate line signals. After the falling gate line signal has stabilized, for example, the gate line system can decrease the shunting resistance of the gate line.

Abstract: The present disclosure relates to devices and methods for reducing power consumption of a display. One electronic display includes a first switch coupled between a first gate of a first transistor and a second gate of a second transistor to selectively connect the first gate to the second gate. The display includes a second switch coupled between the second gate of the second transistor and a third gate of a third transistor to selectively connect the second gate to the third gate. The display also includes driving circuitry that controls the first switch to connect the first gate to the second gate to share a first charge between the first and second gates. The driving circuitry also controls the second switch to connect the second gate to the third gate to share a second charge between the second and third gates. Accordingly, power consumption of the display may be reduced.
