Apparatus and techniques for enhancing characteristics of electronic projection systems are detailed. Included among the techniques are both superimposition of sub-images and tiling of superimposed images, the combination of which can be advantageous in improving resolution of projected images. Pre-modulators and polarizing beam splitters also may be used as parts of the innovative systems.

Digital projection equipment and techniques

Apparatus and techniques for enhancing the dynamic range of electronic projection systems are detailed. Included among the techniques are pre-modulation, luminance compensation, and partial luminance compensation.

Equipment and techniques for increasing the dynamic range of a projection system

A display apparatus includes means for inputting an interlaced video signal comprising signals representative of successive fields in image data produced by scanning successive image frames. Fields of image data that have been derived from single frames of the scanned image frames are determined, and signals produced representative of each of the image frames. A DMD for each color channel is addressed with signals representative of the frames.

Display device driving circuitry and method

A display device includes a deformable mirror device wherein grey scales are displayed using a time division modulation process in which the times or sub-frame periods for which each mirror within the deformable mirror array is switched on. The device includes a selection means for ordering selected sub-frame periods or divided sub-frame periods such that the light directed from each mirror is substantially temporally balanced during each frame period of the display device and/or between consecutive frame periods.
