Abstract

An active OLED display, comprising a plurality of OLED pixels, each of the OLED pixels comprising an anode, a cathode, and a stack of organic layers, wherein the stack of organic layers is provided between and in contact with the cathode and the anode and comprises an electron transport layer, a hole transport layer, and a light emitting layer provided between the hole transport layer and the electron transport layer, and a driving circuit configured to separately driving the pixels of the plurality of OLED pixels, wherein, for the plurality of OLED pixels, a common hole transport layer is formed by the hole transport layers provided in the stack of organic layers of the plurality of OLED pixels, the common hole transport layer comprising a hole transport matrix material and at least one electrical p-dopant, and the electrical conductivity of the hole transport material being lower than 1x10<-3>S.m<-1>and higher than 1x10<-8>S.m<-1>.
