Abstract
An active-matrix organic light-emitting diode microdisplay device having a temperature control system including a temperature sensor and a control means for regulating the temperature of the OLED. The temperature is regulated by a bias transistor within the circuit, operating as a function of the temperature of the panel, such that low panel temperatures cause an increase in voltage of the bias transistor which draws a higher current through the top voltage drive transistor for self-heating the area surrounding the OLED.
