OLED displays are generally considered to be less harmful than LED displays because they do not require a backlight, which can emit blue light that may be harmful to the eyes. OLED displays emit light directly from the individual pixels, resulting in better contrast and color accuracy. However, both OLED and LED displays can still emit blue light, which may cause eye strain and disrupt sleep patterns if used for extended periods of time. It is important to use both types of displays in moderation and take regular breaks to reduce the potential negative effects on eye health. **

It is important to ensure that the vehicle is compliant with the emissions standard displayed on the windshield to avoid any legal issues or penalties. **

Refurbishing displays can be worth it depending on the specific circumstances.

It's important to weigh the cost of refurbishing against the potential benefits and consider factors such as the expected lifespan of the refurbished displays and the impact on the overall aesthetics and functionality of the space. **
