With its higher current and faster switching speed the ISL78365 enables HUDs with high resolution, high coloUr-depth and high frame-rate projections.
The latest innovation in advanced driver assistance systems (ADAS) a vehicle’s HUD keeps drivers focused on the road, providing speed, warning signals and other vital vehicle and navigation information on the windshield directly in the driver’s line of sight.
The new generation of augmented reality laser HUDs are able to offer near-zero latency and a wide field of view. They have been designed to overlay additional real-time information such as traffic signs and a planned turning lane, virtually painting arrows and lines on the road ahead to make navigation directions obvious and easy to follow.
The quad-channel ISL78365 is intended as a complete solution for driving lasers in the scanned-MEMS laser projection systems being deployed in next generation autos. According to Intersil it is the industry’s only laser driver with a fourth channel for supporting a wide variety of laser diode configurations, allowing system designers to achieve the desired brightness and sharp, rich colours with high contrast. It provides sub-1.5ns rise and fall times for faster switching speed than competitive devices, resulting in high frame rate, HD colour video.
The device also offers 10-bit colour and 10-bit scale resolution to support a wide variety of contrast levels for each driver channel. And its flexible synchronous parallel video interface supports pixel rates up to 150MHz or 1900 pixels per line.
The ISL78365’s dynamic power management optimises the laser-diode power supply and offers three power saving modes for improved efficiency and reduced power dissipation to meet system thermal requirements. The programmable multi-pulse return to zero (RTZ) feature reduces speckling, and the device’s wettable flank QFN package simplifies integration into compact laser projection HUDs.
