Release date: 2016-05-13 According to foreign media reports, the US Patent and Trademark Office approved a new technology patent from Apple, which will make the iPad case more "smart". According to the description of the patent document, the new protective case will have a built-in display or even a drawing board similar to Wacom. It is understood that the patent mentions a series of different Smart Cover screen solutions, including combination screens and touch panels are considered. However, it is worth noting that the smarter cover means more energy. However, in the patent, Apple also designed power supply equipment for this kind of protective cover with display. One way is to install a small rechargeable battery inside the protective cover; another way is to install a solar cell inside the protective cover. If the protective cover is not used, the solar cell can be turned over to allow the solar cell to absorb sunlight. At the same time, Apple also pointed out in the patent application materials that AMOLED screens would be ideal displays because they can illuminate a single pixel to turn off the rest of the screen to conserve battery. Apple launched the Smart Cover for the iPad line in 2011, but this official case has not experienced any changes since then. In the meantime, Apple also introduced a Smart Case that protects the front of the iPad.
