3 Description

The DLP® DLP4621-Q1 automotive digital micromirror device (DMD), combined with the DLPC231-Q1 DMD controller and TPS99001-Q1 system management and illumination controller, provides the capability to achieve high-performance, high-resolution headlight systems. The 2:1 aspect ratio supports very wide aspect ratio designs, and the 0.9MP resolution enables high-resolution symbol projection and adaptive driving beam applications. The DLP4621-Q1 optical throughput is optimized to maximize lumens with industry-leading LEDs and laser technology. The DLP4621-Q1 automotive DMD micromirror array is configured for bottom illumination, which enables highly efficient and more compact optical engine designs. The DLP4621-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.
