Abstract
Methods and devices employing in-cell and/or on-cell touch sensor components, including in-cell and/or on-cell black matrix material that also may serve as a touch drive or sense electrode, are provided. In one example, an electronic display may include a lower substrate, an upper substrate, and a black matrix material that shields light between pixels of the electronic display. At least a portion of the black matrix material may form all or part of a component of a touch sensor of the electronic display.
