Abstract
A display system comprises a current source, pulse circuitry, a pulsed laser, control circuitry, and a display surface. The pulse circuitry outputs a first pulse of electrical current based upon electrical current emitted by the current source. The pulsed laser emits first light based upon the first pulse, wherein luminance of the first light is based upon a first amplitude of the first pulse. The control circuitry generates an estimate of pulse history effects on second light that is to be emitted by the pulsed laser, the estimate is generated based upon a parameter of the first pulse and a desired luminance of the second light. The control circuitry causes the pulse circuitry to output a second pulse of electrical current based upon the estimate. Based upon the second pulse, the pulsed laser emits second light with the desired luminance.
