Texas Instruments DLP4620S-Q1 0.46" Automotive DMD

Texas Instruments DLP4620S-Q1 0.46" Automotive Digital Micromirror Device (DMD) is combined with the DLPC231S-Q1 DMD controller and TPS99000S-Q1 system management and illumination controller to provide the capability to achieve a high-resolution, high-performance augmented reality head-up display (HUD). The 2:1 aspect ratio supports various aspect ratio designs. The 0.9MP resolution enables retinal limited displays to be achieved in HUD applications. The DLP4620S-Q1 has a good balance of resolution and optical throughput, enabling a wide field of view and a large driver-eye box for an enhanced user experience. This chipset, coupled with lasers or LEDs and an optical system, enables deep saturated colors of 125% NTSC. It also has a high dynamic dimming ratio of more than 5000:1, extremely high brightness of more than 15,000cd/m2, and high solar load tolerance. The DLP4620S-Q1 DMD is configured for bottom illumination. This feature enables highly efficient and compact optical engine designs to support right and left driver configurations. The Texas Instruments DLP4620S-Q1 device is a panel package for optimized system cost. The package has low thermal resistance to the DMD array to enable efficient thermal solutions.
