Shulou(Shulou.com)11/24 Report--

CTOnews.com, November 15, according to a list released today by the U.S. Trademark and Patent Office (USPTO), Apple has obtained a technology patent for foldable devices outlining systems and methods to control color and brightness compensation for the upper and lower parts of the screen.

In a folded state, a foldable display can use the upper half of the screen to display media content (e.g., mobile applications, videos, websites) and the lower half of the screen as input media (e.g., a virtual keyboard or trackpad) to display LOGO, date and time information, or other information.

If the upper and lower parts have a constant brightness, different vertical light axes may appear in different areas, and the difference in brightness or color between the two folded areas (top and bottom) of the collapsible display may cause image artifacts.

In some types of displays, the apparent brightness of the display will depend on the emission angle relative to the normal direction of the display (perpendicular to the surface of the display).

Apple outlines a related system and method that can control the color and brightness compensation of the upper and lower parts.

For example, when the display is folded, the upper part of the display can display media content, while the lower half of the display can be used as a keyboard or other input media. In some cases, especially in low light conditions, the screen viewing experience may be affected.

The screen can implement different special modes for different folding areas of the display (for example, when the folded display is folded in half, each half of the folded display may have different settings) (for example, pre-adjust or dynamically adjust settings according to environmental conditions) to help simplify the viewing experience. The draft patent attached to CTOnews.com is as follows:

For example, in a low-light or night scene, the monitor may apply a color offset mode, which involves dimming the blue light in the upper half of the display.

The ability to track and / or determine the position of the eyes enables the collapsible display to dynamically adjust the brightness and color output, thereby providing the user with the best viewing experience. In one example, the position of the eye relative to the display can be determined by a camera, a proxy sensor, a facial recognition system (for example, Apple Inc. Face ID ®), the folding angle of the monitor, or any other eye movement tracking method to determine.
