| 20080309832 | PROJECTION DISPLAY APPARATUS AND DISPLAY METHOD APPLIED TO THE SAME - A display apparatus and a display method applied to the same are disclosed, the display apparatus including a lamp which emits a ray of light; and a panel which represents each of a plurality of pixels constituting an image in a manner such that the ray of light emitted from the lamp is reflected against a plurality of micro mirrors; wherein the plurality of micro mirrors form one square micro-mirror. | 12-18-2008 |
| 20090135314 | Method and System for Controlling Deformable Micromirror Devices - A method and system for controlling deformable micromirror devices are provided. In accordance with one embodiment of the present disclosure, a display system includes multiple deformable micromirror devices, a buffer, and a controller. Each deformable micromirror device includes a plurality of micromirrors. The buffer is communicatively coupled, at a first interface speed, to each deformable micromirror device. The buffer is operable to communicate in parallel with the deformable micromirror devices. The controller is communicatively coupled, at a second interface speed, to the buffer. The controller is operable to receive a display input and, in response, generate a plurality signals each corresponding to an optical characteristic of the display input. The controller is further operable to sequentially communicate each of the plurality of signals through the buffer to a corresponding one of the deformable micromirror devices. Each deformable micromirror device receives at least a subset of the plurality of signals. | 05-28-2009 |
| 20090135315 | Diplay apparatus using pulsed light source - The present invention provides a display apparatus, comprising: a light source; at least one spatial light modulator for modulating a luminous flux emitted from the light source; and a controller for processing inputted video image information and for controlling the light source and spatial light modulator, wherein the controller controls the light source and spatial light modulator so that the light source performs pulse emission for a period shorter than a period in which the spatial light modulator is controlled under a modulation state. | 05-28-2009 |
| 20100014008 | WIDE COLOR GAUT HIGH RESOLUTION DMD PROJECTION SYSTEM - A wide gamut high resolution projection system has a light source for generating and emitting light, a prism assembly for separating the light into six primary color light beams, and a plurality of digital micromirror device imagers configured to receive and reflect the primary color light beams. | 01-21-2010 |
| 20140125873 | DRIVE CONTROL APPARATUS AND DRIVE CONTROL METHOD, AND VIDEO OUTPUT APPARATUS - There is provided a drive control apparatus that includes a horizontal control section, and a vertical control section. The horizontal control section controls a scanning mirror for horizontal scanning with laser light, the scanning mirror being driven at a fixed frequency in a horizontal direction. The vertical control section controls the scanning mirror for vertical scanning based on the frequency at which the horizontal control section drives the scanning mirror in the horizontal direction, the vertical control section outputting a vertical drive signal to control the scanning mirror for vertical scanning, the vertical drive signal including an interval in which the laser light is directed vertically from top to bottom and an interval in which the laser light is directed vertically from bottom to top, the intervals alternately producing an output of a predetermined amount. | 05-08-2014 |
