A traditional cluster incorporates two large mechanical gauges with moving pointers, separated by a small to medium size display that renders 2D/3D images. However, many vehicle manufacturers are asking for enhanced graphical image quality with increased resolution. This is perceived to provide better quality, as users now expect the same image quality as high-end consumer devices.
With the advent of even more advanced driver assistance systems, we provide more information to the driver, which necessitates larger displays. This results in the adoption of fully reconfigurable instrument clusters where traditional mechanical gauges, small displays and warning telltales are replaced by one TFT display. Some vehicle manufacturers have started presenting their graphics using image rendering, to replicate a traditional mechanical gauge look and feel.
