Abstract:
1. An organic light emitting diode (OLED) display, comprising: a) an array of OLED display light-emitting elements, each OLED display light-emitting element having two terminals; b) a voltage sensing circuit for each OLED display light-emitting element in the display array including a transistor in each circuit connected to one of the terminals of a corresponding OLED display light-emitting element for sensing the voltage across the OLED display light-emitting element to produce feedback signals representing the voltage across the OLED display light-emitting elements in the display array; and c) a controller responsive to the feedback signals for calculating a correction signal for each OLED display light-emitting element and applying the correction signal to data used to drive each OLED display light-emitting element to compensate for the changes in the output of each OLED display light-emitting element.
