ACTIVE MATRIX DEVICES

摘要

An active matrix device has an array of rows and columns of pixels over a common substrate. Each pixel has a row conductor (12), a column conductor (10) and first and second in-plane electrode patterns (36,40). A first insulator portion (30) is disposed between the row conductor (12) and the first electrode pattern (32) or between the column conductor portion (10) and the second electrode pattern (40). The insulator portion (30) and the surrounding electrode pattern (32 or 40) and conductor portion (12 or 10) define a Metal­Insulator-Metal diode device. The invention provides a MIM-diode based active matrix in­plane switching active matrix device in which the pixel layout is defined on a single substrate. The device of the invention is compatible with low cost manufacturing processes, such as roll-to-roll manufacturing.
