This paper describes a display unit for automotive navigation systems. The distinguishing feature of this display unit is the fact that it employs a 5.6 inch TFT-LCD (Thin Film Transistor Liquid Crystal Display) for on-vehicle use. Compared with a 6-inch CRT, the unit has an expanded effective display area (screen) for improved readability, as well as greater compactness (for savingspace), lighter weight, and lower power consumption. In terms of reliability, the display unit outperforms conventional LCDs due to its wider working temperature range and outstanding resistance to thermal shock. In terms of operation, the system employs a combination of infrared touch switches, hard-key switches and a joy stick to ensure safety and ease of operation.
The 1994 Model MAZDA “SENTIA” is equipped with this newly developed display unit for an automobile navigation system.
