Sapphire glass for HUD Car Head-Up Display HUD (Head Up Display) uses the principle of optical reflection to project important driving-related information onto the windscreen to balance the reflection into the driver's eyes.The function of HUD (Head Up Display) is that the driver does not need to look down to look at the dashboard or navigation, and it displays the relevant driving information on the front windscreen of the vehicle in the form of projection, which may include driving speed, battery voltage, water tank temperature, engine speed, fuel consumption, navigation routes, etc. The HUD is also used to display the information on the front screen of the vehicle. The driving information may include driving speed, battery voltage, tank water temperature, engine speed, fuel consumption, navigation routes, etc. Applying sapphire glass as the glass material of HUD windshield can maintain the glass temperature well, achieve rapid cooling, and help the glass dissipate heat well, thus reducing the loss of reflective instruments, which can bring big profits for the HUD (Head Up Display) automobile new intelligent industry in the long run!
