H/t: Car Scoops
Touchscreen infotainment systems are nothing new, but back in 1986, they were a big deal, especially on a family car. The 1986 Buick Riviera had a touchscreen Graphic Control Center (GCC) as standard equipment, or to be more specific, a CRT screen covered with an invisible Mylar switch panel that utilized transparent conductors. That’s right, this switch panel was row- and column-encoded to perform a specific task on a particular page.
Modern LCD / LED screens turn on instantly, while CRT typically take few seconds to warm up before the display showed anything. To overcome this issue, engineers wired the GCC’s circuitry directly to the driver’s door handle, which means when it’s touched and the door opens or closes, the display comes on, showing the Riviera logo. However, if the screen isn’t touched within 30 seconds, it automatically turns off. When the driver switches on the ignition, the display activates the home page, containing utomatic climate control, AM/FM radio with optional graphic equalizer, trip calculations, gauges, and vehicle diagnostic information.
