ACTIVE MATRIX PIXEL DEVICE

摘要

A method of constructing an active matrix pixel device uses a universal active matrix UAM comprising a matrix array of switching elements 20 whose spacing defines a base pitch and a pixel array comprising a matrix array of pixel electrodes 19 whose spacing defines a pixel pitch. The pixel pitch is greater than the base pitch. A large proportion of the construction process can be carried out before the customisation of the device. Using a common UAM enables a reduction in the time between the customer ordering the device and the completion time. The cost of meeting customer specific requirements for the fabrication of active matrix pixel devices is thus reduced.
