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 high-performance, high-resolution augmented reality head-up 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.
