Controlled light source startup in a display

摘要

Briefly, in accordance with one or more embodiments, a display is powered on to display a projected image, and the operation of one or more display elements are ramped up until a stabilized state is reached. During said ramping up, a light source of the display is powered display at less than full power until the stabilized state is reached. While the light source is operating at less than full power, a splash screen may be displayed. After the stabilized state is reached, the light source can then be operated at or near full power. By providing a light output that is less than full power during ramp up, the display does not need to wait until the stabilized state is reached before the light source is powered on. As a result, the projector provides an output earlier in time to cue to the user that the projector is operating.

1. A method, comprising:
powering on a display to display a projected image, the display including a scanner that deflects on at least one axis; starting the operation of the scanner by providing a drive signal to cause the scanner to start deflecting on a first axis of the at least one axis; receiving a control signal that signifies an amount of torsional deflection of the scanner on the first axis; powering a light source of the display at less than full power while the control signal signifies that the torsional deflection is less than a predetermined value; and powering the light source at or near full power after the control signal signifies that the torsional deflection has reached the predetermined value.
