Abstract: An integrated touchscreen can include light emitting diodes or organic light emitting diodes (LED s/OLEDs), display chiplets and touch chiplets disposed in a visible area of the integrated touch screen. For example, the LEDs/OLEDs, display chiplets and touch chiplets can be placed on a substrate by a micro-transfer tool. The integrated touchscreen can also include electrodes disposed in the visible area of the integrated touch screen. The electrodes can be capable of providing display functionality via the one or more display chiplets during display operation (e.g., operating as cathode terminals of the LEDs during the display operation) and capable of providing touch functionality via the touch chiplets during touch operation (e.g., touch node electrodes can be formed from groups of the electrodes and sensed). In some examples, the touch node electrodes can be formed and coupled to touch chiplets via the display chiplets.

Abstract: A sensing circuit includes at least a first gain stage and a controller for controlling the operation of the first gain stage. The first gain stage includes an amplifier having at least one input and one output, and a feedback loop coupled between the input and the output of the amplifier. The feedback loop includes a first capacitor coupled between the input and the output of the amplifier, and a second capacitor having a first terminal coupled to the input of the amplifier through a first switch and a second terminal coupled to the output of the amplifier through a second switch. The second capacitor is configured to be coupled in parallel to the first capacitor during a first portion of a measurement cycle, and disconnected from the first capacitor during a second portion of the measurement cycle.

Abstract: Display panel redundancy schemes and methods of operation are described. In an embodiment, and display panel includes an array of drivers (e.g. microdrivers), each of which including multiple portions to independently receive control and pixel bits. In an embodiment, each driver portion is to control a group of redundant emission elements.
