Aftermarket head unit integrated circuits and reference designs

Head units with integrated display typically incorporate most infotainment features into one system. This makes the head unit more cost-efficient and easier to install by the OEM. TI has a strong embedded processor and analog portfolio to support your head unit with integrated display designs.

• Typical video interfaces red, green, blue (RGB) parallel, OLDI or HDMI, as well as controls such as I2C, SPI or GPIO.
• Backlight drivers commonly require the boost of voltages and are typically powered off the vehicle battery.
• Converting clock and data lines to low voltage differential signaling (LVDS) helps mitigate EMI.
• Temp sensing is used to ensure the backlight LEDs do not drive the temp beyond the specified panel rating.
