A method is disclosed for spreading a non-periodic color signal sent to a spatial light modulator across a frame period. The method can include the operation of dividing a frame period into a plurality of time slices. A further operation can be assigning a color to each of the plurality time slices. Another operation can be interleaving one or more colors assigned to the time slices across the frame period in a non-periodic manner.

System and method for spreading a non-periodic signal for a spatial light modulator

A projection system is disclosed that includes a light source, a spatial light modulator, and an optical filter. The light source is configured to generate a light beam having a spectral distribution spanning a set of primary colors. The spatial light modulator has an array of pixel elements. Each pixel element is configured to receive a portion of the light beam and to output a modulated light beam with a spectral peak defining one of the set of primary colors. The optical filter is configured to narrow the spectral peak.

Projection system with optical filter

A control circuit for a MEMS (Micro-Electro-Mechanical System) has a semiconductor switch which has a source, a drain and a gate, which is associated with a selected one of spatially arranged fixed and movable plates of a variable capacitor, and is arranged to selectively connect the selected one of the fixed and movable plates with a voltage source. A charge injection control circuit is associated with the semiconductor switch and attenuates current injection into the selected one of the fixed and movable plates of the capacitor.
