Abstract
An electrostatic feedback display array, an active driving method, and a circuit. The array includes a substrate, an insulation layer on the substrate, a passivation layer on the insulation layer, a dielectric layer on the passivation layer, an inductive TFT and a driving TFT in the insulation layer. The passivation layer has an LED and electrically connects to a first electrode of the LED. The dielectric layer has a second electrode. The source of the inductive TFT electrically connects to the second electrode. The driving TFT has a source electrically connected to the first electrode device, and a gate electrically connected to a source of inductive TFT. The invention utilizes TFTs to control a touch electrostatic feedback switch, integrates electrostatic feedback, capacitance sensing and display functions, realizes boundary perceptible haptic feedbacks, avoids direct connection and harmful consequences of high voltage source to the human body, and improve safety.
