Title:
光発光消滅素子の行列ディスプレイパネルを駆動する回路及びその回路を採用した行列ディスプレイ装置
Document Type and Number:
Japanese Patent JP3989413
Kind Code:
B2
Abstract:
A circuit for driving a photoluminescence quenching device (PQD) of a flat panel display, each PQD defining a pixel at a crossing of a scan line and a data line, includes an activation transistor and a driver transistor. The activation transistor is turned on according to potential of the scan line and outputs a potential of the data line. The driver transistor is connected between a reference voltage terminal of the circuit and a PQD. When the activation transistor is turned on, the driver transistor applies to the anode of the PQD a potential that is applied to the reference voltage terminal, according to the potential of the data line. In an emissive mode of the PQD, when the driver transistor is turned on, a forward voltage is applied between the anode and the cathode of the PQD so that the PQD emits light. In a re-emissive mode, when the driver transistor is turned off, no voltage is applied between the anode and the cathode of the PQD so that the PQD emits light by photoluminescence.
