Abstract: Extension devices such as upstream facing port devices (UFP devices) and downstream facing port devices (DFP devices) connect via an extension medium. When a UFP device and a DFP device pair with each other, DisplayPort video and/or audio information from a DisplayPort source device can be presented by a DisplayPort sink device, which are coupled to the UFP device and DFP device, respectively. In some embodiments, the DFP device may train a DisplayPort link to the DisplayPort sink device regardless of whether it is receiving actual data from a UFP device, and may provide placeholder data to the DisplayPort sink device in order to keep the link active. The DFP device may then replace the placeholder data with the actual data from the UFP device, once received, and may thereby seamlessly switch the DisplayPort sink device from presenting placeholder data to presenting data from the DisplayPort source device.

Abstract: For an example method of reducing diffraction artifacts in a displayed image from a digital image projection system, a digital controller is coupled to a spatial light modulator. The spatial light modulator includes a two dimensional array of pixels. The method includes receiving signals containing pixel image data and processing the pixel image data to determine a desired gray scale for a pixel. The desired gray scale is compared to achievable gray scales of the digital image projection system. An upper bounding achievable gray scale is determined, and a lower bounding achievable gray scale is determined. Also, a dithering percentage for the desired gray scale is determined. The method chooses one of the upper bounding achievable gray scale and the lower bounding achievable gray scale. Also, a modified lower bounding gray scale is chosen to reduce the dithering percentage.

Abstract: A new projector design combines one spatial light modulator that affects only the phase of the illumination, and one spatial light modulator that only affects its amplitude (intensity). The phase-only modulator curves the wavefront of light and acts as a pre-modulator for a conventional amplitude modulator. This approach works with both white light and laser illumination, generating a coarse image representation efficiently, thus enabling, within a single image frame, significantly elevated highlights as well as darker black levels while reducing the overall light source power requirements.
