The patent, which was identified by Patently Apple, demonstrates Apple’s efforts to address these problems. The business envisions a keyboard with openings through the top and bottom layers in each key. Each key on the keyboard could be intelligently illuminated by the backlighting underneath to display various symbols and letters.  Another possible scenario is also depicted in the patent, where the light source is a “array of LEDs, such as a display using micro-LED or OLED pixels.” This would be a more sophisticated application of a comparable concept, with further controls, customizability possibilities, and overall versatility.  -Patent  It’s crucial to keep in mind that Apple is continuously thinking about new technologies while reviewing patent applications. Every day, patent applications are submitted, and Apple has innumerable ideas that are never implemented. What Apple is describing in their patent application is quite innovative. But it’s not an easy operation to perform, as we’ve learned from prior attempts by Apple to update keyboard technologies.
