Description

This reference design implements a video over LVDS solution for automotive infotainment applications.It highlights the support of multi-touch with haptic feedback, LCD backlight control, and ambient light sensing, without the introduction of dedicated support lines back to the host processor. This design is implemented using two boards. The main electronics board, SAT0059 is where the deserializer, microProcessor, backlight controller, haptics drivers and power supply are located. The LCD interface board, SAT0096, is a physical and electrical interface to a specific LCD panel. It connects to the SAT0059 through a Samtec board to board connector and provides connection points for the LCD panel, touchscreen, backlight connections and haptic drivers. The SAT0096 is designed for a Microtips UMSH-8596MD-20T display. If a different display is to be used, a new LCD Interface board would likely need to be designed.

Features
  • Wide input voltage range: off battery 4.5V to 40V power supply
  • All video and support communications through LVDS
    o Supporting 24 bit RGB Video
    o 400Kbps back channel I2C connection for multi-touch input
  • Haptic feedback
  • State of art I2C/SPI interface LED backlighting controller with dimming ratio of >10,000:1, switching frequency ~2.2MHz, hybrid dimming and saftey and fault tolerances/functions
  • Backlight adjustable to inputs
    o Ambient light sensor
    o Thermistor inputs on the LCD and the back light to enable thermal protection
