Abstract
Some disclosed devices may include a thin-film transistor (TFT) substrate, an electret film and an array of addressable pixels electrically connected to the TFT substrate. The array of addressable pixels may be an array of electrodes proximate a first side of the electret film. The electrodes maybe capable of coupling charge from the electret film to the TFT substrate in response to an acoustic wave.
