3 Description

The DLP? DLP4620S-Q1 automotive digital

micromirror device (DMD), combined with the

DLPC231S-Q1 DMD controller and TPS99000S-Q1

system management and illumination controller,

provides the capability to achieve high-performance,

high-resolution augmented reality head-up display

(HUD). The 2:1 aspect ratio supports very wide

aspect ratio designs, and the 0.9MP 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 a 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, extremely high

brightness of more than 15,000cd/m2, high dynamic

dimming ratio of 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.
