Abstract: A system is disclosed. The system can comprise drive circuitry included in a first component of the system, the drive circuitry configured to drive a first touch electrode on a touch sensor panel. The system can also comprise a driving line configured to couple an output of the drive circuitry to the first touch electrode. The system can also comprise a feedback line configured to couple the output of the drive circuitry to an input of the drive circuitry, wherein a first end of the feedback line is coupled to the input of the drive circuitry at the first component, and a second end of the feedback line is configured to be coupled to the output of the drive circuitry at a second component, different from the first component, of the system.

Abstract: An apparatus is disclosed. In some examples, the apparatus comprises a display panel comprising a plurality of display pixels. In some examples, the apparatus comprises a plurality of temperature sensors disposed at different portions the display panel, wherein the plurality of temperature sensors comprise ratioed pairs of thin film transistors and the ratioed pairs of thin film transistors are formed on the display panel. In some examples, the apparatus comprises control circuitry for changing illumination properties of the plurality of display pixels based on changes is temperature detected by a proximate temperature sensor of the plurality of temperature sensors. In some examples, the ratioed pairs of thin film transistors are operated in a sub-threshold mode.

Abstract: A system is disclosed. The system can comprise dynamic drive circuitry configured to drive a plurality of electrodes on a touch screen. The system can also comprise a switching circuit configured to selectively couple the dynamic drive circuitry to one or more of the plurality of electrodes. The system can also comprise a display circuitry configured to selectively update a plurality of display pixels on the touch screen. The dynamic drive circuitry can be configured to set its output based on which of the plurality of electrodes are selectively coupled to the first drive circuitry and which of the display pixels are updated by the display circuitry.
