3 Description
The DLP3940S-Q1 digital micromirror device (DMD)
is a digitally controlled micro-electro-mechanical
system (MEMS) spatial light modulator (SLM)
that enables bright 1080p FHD to achieve highperformance,
high-resolution augmented reality headup
display (HUD). The 16:9 aspect ratio supports very
wide aspect ratio designs, and the high resolution
enables retinal limited displays to be achieved in HUD
applications. The DLP3940S-Q1 offers a balance of
optical throughput and resolution, enabling a wide
field of view and a large driver eye box for enhanced
user experience. This chipset, coupled with LEDs or
lasers and an optical system, enables deep, saturated
colors of 125% NTSC, high brightness of more than
15,000cd/m2, high dynamic dimming ratio of more
than 5000:1, and high solar load tolerance. The
DLP3940S-Q1 automotive DMD micromirror array is
configured for side illumination, which enables highly
efficient and more compact optical engine designs.
The DLP3940S-Q1 device is available in a panel
package for optimized system cost. The package has
low thermal resistance to the DMD array to enable
efficient thermal solutions.
