Laser display with improved brightness control

A system comprising:

• a display comprising a laser;
• a circuit configured to measure a voltage at the laser at a current;
• and
• a driver configured to:
• generate a sequence of currents of the laser based on a target sequence of brightness levels of the laser, the current, and the voltage;
• maintain a difference between an actual sequence of brightness levels output by the laser and the target sequence of brightness levels of the laser below a threshold of 20%, the brightness levels being photometric brightness levels;
• and
• modulate an operating current of the laser based on the sequence of currents.

A non-transitory computer-readable medium including instructions that, when executed, are configured to cause at least one processor to perform a method, the method comprising:

• measuring a first voltage of a diode at a first current of a diode of a display system;
• measuring a second voltage of the diode at a second current of the diode at a time after measuring the first current of the diode;
• generating a sequence of currents of the diode based on a target sequence of brightness levels of the diode, the second current, and the second voltage;
• and
• modulating an operating current of the diode based on the sequence of currents,
• the measuring of the first voltage and the measuring of the second voltage being suspended when the diode is not emitting.
