Abstract
An electrostatic latent image is formed when the print controller of a print engine wirelessly transmits digital printing signals. Driving electronics receives the wirelessly transmitted digital printing signals and transmits digital signals to address plurality of thin-film transistors (TFTs) individually in a TFT array. Driving electronics also transmit pixel voltages to bias individual TFTs in the TFT array which in turn drives the hole injecting pixels overcoated with a charge transport layer to generate the electrostatic latent image on the surface of the charge transport layer in response to the received digital printing signals.
