The present invention includes systems and methods for a multi-primary color system for display. A multi-primary color system increases the number of primary colors available in a color system and color system equipment. Increasing the number of primary colors reduces metameric errors from viewer to viewer. One embodiment of the multi-primary color system includes Red, Green, Blue, Cyan, Yellow, and Magenta primaries. The systems of the present invention maintain compatibility with existing color systems and equipment and provide systems for backwards compatibility with older color systems.

A display apparatus of the present disclosure includes: a first optical system that generates illumination light whose light emitting luminance is variable; a light modulation unit that transmits the illumination light from the first optical system and whose transmissivity is variable; a second optical system that includes a light modulation device and optically modulates the illumination light from the first optical system by using a pulse width modulation technology, the illumination light having passed through the light modulation unit; and a control unit that controls the light emitting luminance of the illumination light from the first optical system and the transmissivity of the light modulation unit in any combination.

Light field projector devices or alternative projector devices may be used individually or in combination with one or more other projectors which can be arranged to form a multiplexed direct projection light field display. The arrangement of projector devices may have an individual or shared display optical system.

A laser projection apparatus includes a laser source assembly, a display control circuit, a signal shaping circuit and a laser source driving circuit. The display control circuit is configured to output a first driving signal and a second driving signal. The signal shaping circuit is coupled to the laser source driving circuit, and is configured to shape the first driving signal based on a shaping signal to obtain a target driving signal. A frequency of the target driving signal is higher than a frequency of the first driving signal. The laser source driving circuit is coupled to the laser source assembly, and is configured to receive the second driving signal and the target driving signal, and drive the laser source assembly to be turned on or turned off in response to the second driving signal and the target driving signal.
