7.1 Overview

The DLP801RE digital micromirror device (DMD) is a 0.8-inch diagonal spatial light modulator that consists of an array of highly reflective aluminum micromirrors. The DMD is an electrical input, optical output micro-optical-electrical-mechanical system (MOEMS). The fast switching speed of the DMD micromirrors, combined with advanced DLP image processing algorithms, enables the micromirror array to display a full 1920 × 1200 pixel image at a 120 Hz frame rate. The electrical interface is a low voltage differential signaling (LVDS) interface. The DMD consists of a two-dimensional array of 1-bit CMOS memory cells. The array is organized in a grid of M memory cell columns by N memory cell rows. Refer to the Section 7.2. The positive or negative deflection angle of the micromirrors can be individually controlled by changing the address voltage of underlying CMOS addressing circuitry and micromirror reset signals (MBRST).

The DLP 0.8-inch WUXGA chipset is comprised of the DLP801RE DMD, DLPC4430 display controller, the DLPA300 micromirror driver and the DLPA100 power management and motor driver. For reliable operation, the DLP801RE DMD must always be used with the DLP display controller and the power and motor driver specified in the chipset.
