Two display inventions reveal Apple s work on Content-Dependent Brightness Adjustment & Cancelling the Ghosting Phenomena
Last Thursday the US Patent & Trademark Office published two patent applications from Apple that relate to electronic devices with displays. In the key patent, Apple s invention relates to displays with content-dependent brightness adjustment. The second patent relates to a cancellation architecture for cancelling the ghosting phenomena.
Apple notes in a new patent application that if care isn t taken, displays may be damaged by displaying bright content for prolonged periods of time, displays may be operated with brightness levels that consume excessive power, user preferences may not be taken into account when adjusting display brightness, and displayed content may exhibit visible artifacts. Addressing these concerns while displaying content with a pleasing appearance is challenging.
