Apple’s new breakthrough in screen technology: clarity enhanced by 90% under strong light

Recently, the U.S. Trademark and Patent Office announced a screen technology patent obtained by Apple. It is reported that this technology can effectively reduce up to 90% of strong light under direct sunlight outdoors, thereby significantly improving the visibility of the screen.

Apple noted in the patent description that strong ambient light may have a negative impact on the viewing experience of the screen, such as reducing contrast and causing display content to be blurry. In order to solve this problem, Apple improved the user experience by innovatively embedding light-shielding elements similar to "louvers" into the screen. These light-shielding elements can be statically or dynamically adjusted according to changes in ambient light intensity to ensure that the screen display is always at its best.

It is understood that these light-shielding elements adopt a special design, including an asymmetric "louver" film structure, and are equipped with adjustable components to optimize the performance of the display under different lighting conditions. The system uses an ambient light sensor to detect the light level of the surrounding environment, and then adjusts the light-shielding elements in the display based on the detected light level to ensure that users get the best visual experience.

In addition, the patent also reveals a new technology, a diffuser that can automatically adjust according to the ambient light level and is embedded in the screen. The diffuser has at least two different haze states and can automatically adjust according to changes in ambient illumination. In a dark environment, the diffuser will be in a high diffusion state to reduce the screen door effect of the display and improve visibility; while in a brighter environment, the diffuser will switch to a low astigmatism state to reduce the screen door effect of the display. Increases the contrast of your display to make content more visible. This self-adjusting diffuser can effectively improve the visual effect of the display under different lighting environments, enhance the user experience, and provide users with a more comfortable and clear display.

The display also contains an adjustable tone layer. This layer has at least two states with different transmission levels. Under low ambient illumination, it is in a high transmittance state to improve display efficiency; while under high ambient illumination, it reduces the light transmittance to increase the contrast of the display. This kind of intelligent adjustment can ensure that the display effect can maintain high-quality performance under different lighting conditions, and users can get a clearer and more comfortable viewing experience.

The patent sketch shows one possible way to realize the light-shielding element: by coating it with a dark material that transmits only 10% of the incident light while absorbing the remaining 90%. Such a design requires that ambient sunlight must pass through two such solar suppression elements before reaching the observer/user, thereby reducing the brightness of the reflected sunlight to 1% of the initial sunlight brightness. This approach significantly improves screen visibility outdoors in sunlight.
