ACTIVE MATRIX LED PIXEL DRIVING CIRCUIT AND LAYOUT METHOD

摘要

A unit pixel driver circuit includes a capacitor configured to store a voltage corresponding to a desired pixel brightness and a control block. The control block may include a first, second third and fourth transistors, all of which are connected together, both in parallel and in series. The control block controls, based on the voltage stored in the capacitor, the amount of current flowing through a pixel LED. The first transistor, second transistor, third transistor and fourth transistor all share a common gate geometry size.
