Why Are Screens Hard to See in Sunlight?
Screens are hard to see in sunlight because the intense ambient light overpowers the display’s brightness, and reflections and glare on the screen reduce the contrast, making images and text appear faded. Sunlight’s brightness, often ranging from 1,000 to 10,000 nits, far exceeds the typical output of a standard LCD, which is usually between 300-500 nits. On top of that, uncoated screens reflect sunlight, scattering light across the surface and making it harder to see what’s displayed(Why Do High-Lumen Lights Fail in Outdoor Environments?).
Some display technologies handle this differently. For example, OLED screens can struggle in direct sunlight because their peak brightness is lower than high-brightness LCDs built for outdoor use. However, new features like anti-reflective coatings and polarizers are making sunlight readable displays better over time.
Brightness and Contrast in Sunlight
- Brightness Comparison: A standard LCD’s 300-500 nits can’t compete with sunlight’s 1,000-10,000 nits, causing the screen to look dim.
