Method for canceling crosstalk of QLED display panel and QLED display panel

摘要

A method for application in a QLED display device is provided for cancelling optical crosstalk occurring in a QLED display panel consisting of M number of anode wires, N number of cathode wires, and M×N number of QLED elements. In case of the method being implemented in the QLED display device, a control unit is configured for controlling a column driver unit to supply a positive bias voltage to at least one QLED element that is addressingly selected. In the meantime, the control unit also controls a low driver unit to supply a reverse bias voltage to each of the QLED elements that are not selected. In such case, when the addressingly-selected QLED element achieves a light emission normally, each of the QLED elements that are not selected is reversely biased for failing to produce optical crosstalk.
