Abstract

An active matrix display comprises a plurality of OLED pixels each having an associated current-programmed pixel drive circuit, the pixel drive circuit having a pixel select line and a current programming input for programming the associated OLED pixel when said pixel select line is active. The display further comprises at least one distributed cascode transistor shared between a set of said pixel drive circuits, the distributed transistor comprising a set of transistors each having an input connection, an output connection and a control connection. Each of the transistors of the set is in physical proximity to a respective pixel drive circuit and has its output connection connected to the current programming input of said respective pixel drive circuit. The input connections of the transistors of said set are connected together in parallel, the output connections of the transistors of the set are connected together in parallel, and the control connections of the transistors of the set are connected together in parallel. The parallel-connected input connections are connected to a common current programming line for said set of said pixel drive circuits.
