1. An apparatus, comprising:
- an input portion adapted to receive input data for a light modulator;
an output portion adapted to output data to the light modulator; and
a flow controller coupled to the input portion and the output portion, wherein the flow controller is configured to control the flow of data from the input portion to the output portion, and wherein the flow controller is configured to control the output portion to output data to the light modulator in accordance with an output timing signal which is decoupled from an input timing.

Abstract
In some embodiments, a light processing system includes a light modulator and a controller configured to control outputting data to the light modulator in accordance with an output timing signal which is decoupled from an input timing. The output timing signal may come from a color switching device. For example, in some embodiments, frame synchronization for a projection display is performed by a data flow controller instead the color wheel controller. In some embodiments, frames may be repeated or dropped. Other embodiments are disclosed and claimed.
