Systems and methods for controlling scanning mirrors for a display device

A scanning laser projector system, comprising:

• a video processor configured to receive RGB pixel data, process the received RGB pixel data, and output processes RGB pixel data, wherein the video processor processes the received RBG data by performing at least one of gamma correction, color space conversion, interpolation or decimation;
• red (R), green (G) and blue (B) light emitting elements;
• a light emitting element driver configured to receive the processes RGB pixel data from the video processor and output drive signals configured to drive the R, G and B light emitting elements, thereby causing the R, B and B light emitting elements to emit light;
• projector optics configured receive at least a portion of the light emitted by the R, G and B light emitting elements;
• a bi-axial scanning mirror configured to reflect light directed toward the bi-axial scanning mirror by the projector optics;
• a scanning controller configured produce a horizontal (H) and vertical (V) scanning control signal that is used to control the bi-axial scanning mirror;
• wherein the H and V scanning control signal includes H scanning frequency content that is used to control a H scanning frequency of the bi-axial scanning mirror, and V scanning frequency content that is used to control a V scanning frequency of the bi-axial scanning mirror;
• and
• wherein the scanning controller is configured to produce the H and V scanning control signal such that the H scanning frequency content has a null at DC, and the V scanning frequency content has a null at the H scanning frequency.
