Discovery™ 4000 Kit
The Discovery™ 4000 Kit offers developers extremely high performance and high resolution with the new .95" 1920x1080p 2xLVDS DMD, an optical semiconductor module that allows developers to manipulate light digitally. When integrated with light source and optics, this unique device creates binary light patterns with speed, precision, and efficiency far surpassing that of other spatial light modulators. The Discovery™ 4000 Chip Set provides substantial performance improvements including increased data rate, frame rate and flexible random row addressing. The Discovery™ 4000 also supports the .55" diagonal and .7" XGA LVDS.
The .95" 1080p DMD 2xLVDS (400 MHz DDR, Low Voltage Differential Signal) consists of a 1920x1080 array of micro-mechanical mirrors on a 13.68 um mirror pitch. Each mirror can be individually deflected at +/-12° about a hinged diagonal axis. Deflection polarity (positive or negative) of mirrors is individually controlled by changing the binary state of the underlying CMOS control circuitry and mirror reset signal.
The 1920x1080 mirror are driven in 16 separate reset blocks that can be address globally or one at a time. Effectively, the DMD is an electrical input, optical output memory device.
The DLP® Discovery™ 4000 Chip Set features the DMD and other supporting devices. Unlike TI DMD controllers optimized for projection display, Discovery™ 4000 is designed to support a wide variety of DMD applications by delivering maximum flexibility in formatting and sequencing data light patterns.
