Micro display controlling system

A projection display system, comprising:

• a frame-memory controller, comprising:
• at least two frame memories, wherein a first frame memory configured to store a first single-color data frame corresponding to a first color, and a second frame memory configured to store a second single-color data frame corresponding to a second color;
• at least one color-display panel, configured to emit a plurality of single-color lights;
• an image merger configured to combine the plurality of single-color lights emitted from the at least one color display panel, the image merger is further configured to direct the plurality of single-color lights toward a same direction;
• a data processor, comprising:
• at least two data formatting processors, each data formatting processor is further configured to process a single-color data frame and provides a panel controlling signal and processed frame data, wherein each panel controlling signal is configured to control the at least one color-display panel;
• and
• a data output interface, comprising at least two sub-output interfaces, each coupled to one of the data formatting processors, wherein each of the data formatting processors provides the panel controlling signal and the processed frame data to the output interface, the output interface further providing the panel controlling signal and the processed frame data to the at least one color display panel.
