Temperature-based dynamic laser tuning to promote display uniformity

A method for controlling an augmented-reality device including a near-eye display, wherein the near-eye display includes a laser light source configured to perform a display scan operation, wherein the display scan operation includes, for each pixel of a plurality of pixels that collectively form a field of view of the near-eye display, generating a pre-color pulse and subsequently generating a primary color pulse, the method comprising:

• receiving, from a temperature sensor of the augmented-reality device, an operating temperature measurement of the laser light source;
• for each pixel of the plurality of pixels of the near-eye display,
• dynamically tuning an amplitude of the pre-color pulse based at least on the operating temperature measurement of the laser light source;
• and
• generating, via the laser light source, the pre-color pulse with the dynamically tuned amplitude, and subsequently generate the primary color pulse.

• a temperature sensor configured to output an operating temperature measurement of the laser light source;
• a logic subsystem;
• and
• a storage subsystem holding instructions executable by the logic subsystem to:
• receive the operating temperature measurement from the temperature sensor;
• and
• for each pixel of the plurality of pixels of the near-eye display,
• dynamically tune at least one of an amplitude and a pulse width of the pre-color pulse based at least on the operating temperature measurement of the laser light source;
• and
• generate, via the laser light source, the pre-color pulse with the dynamically tuned amplitude and/or the dynamically tuned pulse width, and subsequently generate the primary color pulse.
