Apple has recently obtained a new patent, which can prevent the titanium alloy eyes of iPhone users from being damaged by the "luminescence shock".

When the user lights up the iPhone screen at night, although the surrounding environment is dark, the screen brightness will not be adjusted to the appropriate brightness immediately, but it will take a few seconds to adjust the brightness by itself, but the user's eyes have been hurt by the strong flash. And this new patent of Apple Luminescence Shock Avoidance in Display Devices（ It is temporarily translated as "screen independent anti strong flash" ）, it can avoid this situation. It can detect the darkness of the surrounding environment in advance and limit the brightness of the iPhone screen according to the corresponding situation.

The principle of this function is to detect the surrounding brightness through the light sensor on the iPhone, and then when the user turns on the iPhone, the screen brightness will be adjusted to the appropriate level immediately. I believe you have also experienced this situation. When you turn on your mobile phone at night, the screen brightness is too high, and suddenly your eyes will be very uncomfortable. It often takes a few seconds to slow down after being blinded. So this function is very practical for night owls. iOS 12 is online?
