Abstract: An electronic device can include integrated micro circuitry configurable for optical sensing and touch and/or proximity sensing. An integrated touch screen can include light emitting diodes or organic light emitting diodes and chiplets. In some examples, the LEDs/OLEDs and chiplets can be disposed in a visible area of the integrated touch screen. In some examples, some or all of the chiplets can be disposed outside of the visible area of the integrated touch screen. In some examples, the chiplets can include display driving circuitry and touch sensing circuitry, and can optionally perform optical sensing using the touch sensing circuitry. In some examples, the chiplets can include separate touch chiplets configured to perform touch sensing (and/or optical sensing) and display chiplets configured to perform display functionality (and optionally provide some switching functionality).
