Diagonal Pixel Arrangement. Low Voltage Differential Signaling (LVDS) data interface, Double Data Rate (DDR). Pixel
Architecture is SPD with DarkChip3™.
4.3.3 DAD1000
The DAD1000 (IC9021) DMD Power and Reset Driver provides the high-voltage power supplies and phased reset driver
functions for a family of Digital Micro-mirror Devices (DMDs). The DAD1000 is programmable and controllable to meet
all current and anticipated DMD requirements.
The high-voltage power supply function generates the three required DMD voltage levels: VBIAS, VRESET, and
VOFFSET. These three supplies are programmed and controlled through a TTL and CMOS compatible serial interface. The
DAD1000 also contains a +5 volt supply for internal logic functions and external color wheel control requirements.
The DAD1000 switches outputs between VBIAS, VRESET and VOFFSET voltage levels to form DMD reset waveforms.
VBIAS may be supplied directly to the DMD to bias the border mirrors to the off state. VOFFSET is also supplied directly
to the DMD as DMDVCC2. A fourth DMD power supply, DMDVCC, is supplied directly to the DMD by other circuitry.
4.3.4 CYCLONE
SmoothPicture™ is a technique for storing and displacing consecutive subframes of the image to allow the complete frame
of data to be projected, generating two on-screen pixels with one DMD mirror. SmoothPicture™ also significantly reduces
image pixelization.
