3 Description

The DLP4620S-Q1 automotive digital micromirror

device (DMD), combined with the DLPC230SQ1

DMD controller and TPS99000S-Q1 system

management and illumination controller, provides

the capability to achieve high-performance, highresolution

augmented reality head-up display (HUD).

The 2:1 aspect ratio supports very wide aspect ratio

designs, and the 0.9-MP resolution enables retinal

limited displays to be achieved in HUD applications.

The DLP4620S-Q1 has a good balance of optical

throughput and resolution enabling wide field of

view and 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, extremely high brightness of more

than 15,000 cd/m2, high dynamic dimming ratio more

than 5000:1, and high solar load tolerance. The

DLP4620S-Q1 automotive DMD micromirror array

is configured for bottom illumination, which enables

highly efficient and more compact optical engine

designs to support left and right driver configurations.

The DLP4620S-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.
