ACTIVE MATRIX ARRAY DEVICE, ELECTRONIC DEVICE HAVING AN ACTIVE MATRIX ARRAY DEVICE AND PICTURE QUALITY IMPROVEMENT METHOD FOR SUCH AN ELECTRONIC DEVICE

摘要

An active matrix array device (100) has a plurality of active matrix array elements (110a-i), which each have a charge storage element (112a-I) and a capacative output element (114a-I), and which are coupled to respective addressing conductors (172, 174, 176) and to respective charging conductors (142, 144, 146) via respective thin film transistors (116a-I). The charging conductors (142, 144, 146) are coupled to the respective stages (122, 124, 126) of a driver circuit (120) via respective voltage modification circuits (132, 134, 136), which are responsive to respective voltage waveform generators (252, 254, 256). The respective voltage modification circuits (132, 134, 136) are arranged to modulate the outputs of the stages (122, 124, 126) with a voltage waveform from the respective voltage waveform generators (252, 254, 256) in order to overdrive the addressed matrix array element during a part of its charging cycle. This way, the charge time of the corresponding charge storage element and/or the corresponding output element is reduced.
