Automotive TFT LCD Display Solution
Texas Instruments
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.
