XG-NV7XU OPTICAL ADJUSTMENT What to readjust after replacement Readjustment Reflection lens Not needed. Cylinder mirror Not needed. Mirror A Not needed. Mirror B Not needed. Requirements for adjustments Phillips screwdriver, red gradation pattern signal. Color wheel Enter the red gradation pattern from RGB1. Make sure the pattern appears normal on screen. If not, loosen the wheel sensor screw and move the sensor up and down until the gradation appears crisp on screen.
XG-NV7XU DMD AND PRINCIPLE OF OPTICAL SYSTEM 1. Outline of DMD (Digital Micro Mirror Device) The DMD is one of the ultra-micro electromechanical systems called MEMS (Microeletromechanical System). The DMD can be fabricated by employing the existing 0.8 micron rule, which is the established semiconductor manufacturing technology.
XG-NV7XU 3. Switching of Mirror The mirror reflects light in one of two directions, depending of the state of underlying memory cell. The mirror rotates by a force of electrostatic attraction produced by voltage difference between the mirror and the memory cell. With the memory cell being in the ON (1) state, the mirror rotates by +10 degrees. With the memory cell being in the OFF (0) state, the mirror rotates by -10 degrees. Figure 5. shows a close-up of DMD mirrors operating.
XG-NV7XU 4. Digital Light Processing Signal and Gray Scale When the mirror rotates, it reflects incident light either into or out of the projection lens to create a burst of digital light pulses, which the eye interprets as an analog image. In binary pulse width modulation, the DMD accepts electrical words representing the gray level of brightness at its input, and puts out optical words, which are interpreted by the observer’s eye as analog brightness level.
