Abstract
Micro light-emitting diode display driver architectures and pixel structures are described. In an example, a driver circuit for a micro light emitting diode device includes a current mirror. A linearized transconductance amplifier is coupled to the current mirror. The linearized transconductance amplifier is to generate a pulse amplitude modulated current that is provided to a set of micro LEDs connected in parallel to provide fault tolerance architecture.
