[LaJason]

Dispclock on the Teana car is the head-up display activation button. When pressed, a transparent projection display device will appear in front of the vehicle's instrument panel. The function of the head-up display: The head-up display, abbreviated as HUD and also known as the heads-up display system, is a driver-centered, blind-operation, multi-functional instrument panel. Its purpose is to project important driving information such as speed and navigation onto the windshield in front of the driver, allowing the driver to view crucial driving information like speed and navigation without having to lower or turn their head. Classification of head-up displays: Suspended HUDs are fixed on the sun visor above the car driver, resulting in the HUD information being projected onto the upper area of the windshield. Dashboard-mounted HUDs, on the other hand, are fixed on the central console in front of the driver, which means the HUD information will be projected onto the front area of the windshield.
