Mobile screen brightness easily auto-adjusts in a variety of conditions so that it remains easily visible. However, if the screen faces the sun, the objects on the screen become difficult to discern with the human eye.

What could be the reason that best explains this phenomenon?

Depending on which technology your phone uses, the image may be formed by lighting individual pixels, or it may be formed by a backlight being selectively blocked. Either way, it’s only the light coming from inside the screen, not what’s reflected off its surface, that can show the image. The reflection can interfere directly, but even if it doesn’t, the screen isn’t nearly as bright as full sunlight. It gets overwhelmed. The comparative differences from one part of the screen to another are tiny next to the difference between your phone’s light and the sun… and your pupils contract to adjust to the latter. novel online
