DRIVING CIRCUIT FOR CURRENT PROGRAMMED ORGANIC LIGHT-EMITTING DIODE DISPLAYS

摘要

A load driving circuit for a load having a parasitic capacitance associated therewith is provided. The load being current programmed. The driving circuit has a data line having a voltage controlling the load, a feedback loop having a lowpass filter for monitoring the voltage of the data line; and a current source for providing a current to the data line; the current source being controlled by a signal line and an output from the lowpass filter.
