Patent ID: 8681194

Claim:
A method of forming an electrostatic latent image, comprising: receiving, at a translucent media, optically encoded serially transmitted digital printing signals, which were transmitted from light source being driven by a controller; detecting, by a photodetector, the received optically encoded serially transmitted digital printing signals from the translucent media; converting the optically encoded digital printing signals into data signals including driving signals and pixel voltages; receiving, via the rotary electrical contact, operating voltages including a TFT drive voltage potential; transferring the driving signals to address a plurality of thin-film transistors (TFTs) individually in a TFT backplane in response to the received data signals; and transferring pixel voltages to bias individual TFTs in the TFT backplane to generate the electrostatic latent image in response to the received data signals, wherein the TFT drive voltage potential is transferred to the TFT backplane and further wherein creating the electrostatic latent image further comprises applying an electrical bias to one or more pixels via the individual TFTs in the TFT backplane to either enable hole injection or disable hole injection at the interface of the one or more pixels and the charge transport layer.
