TIDA-00169 Reference Design

Texas Instruments

Automotive TFT LCD Display Solution

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 supplyAll 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/functionsBacklight adjustable to inputs o Ambient light sensor o Thermistor inputs on the LCD and the back light to enable thermal protection
