The topic of foldable iPhones has been with us ever since Samsung introduced the first Galaxy Fold. Patents keep cropping up that reveal Apple's world of ideas. This time it's about a display technology that can heal or repair itself.<\/strong><\/p>\n\n\n\n

Apple recently filed a patent describing a self-healing display. The panel is intended for use in foldable devices. This could potentially include a foldable iPhone. The idea would solve one of the main problems with foldable smartphones and would certainly have spared Samsung the disaster with the first Galaxy Fold. The more often a display is opened and closed, the more likely it is to accumulate dust and similar debris. These can permanently damage the folding mechanism. Apple's idea addresses precisely this problem. <\/p>\n\n\n\n

Apple Patent: Self-healing material could be the solution<\/h3>\n\n\n\n\n\n\n\n

Displays are typically formed from rigid, planar substrates. Although satisfactory in many situations, such rigid displays may be difficult to integrate into certain devices, such as devices with flexible housings.<\/p>\n\n\n\n

During operation of an electronic device, the display cover layer for the electronic device may become scratched or dented. To improve the aesthetics of the electronic device, it may be desirable for the presence of scratches and dents to be minimized. To reduce the number of dents, scratches, or other imperfections in a display cover layer, the display cover layer may include a layer of self-healing material.<\/p>\n<\/blockquote>\n\n\n\n

According to the patent description, the use of self-healing material would be the best solution to the problem. The process could be triggered during the charging process, for example.<\/p>\n\n\n\n

Foldable iPhone: Heat could stimulate self-healing<\/h3>\n\n\n\n
\n

In the layer of self-healing material, self-healing can occur without being prompted (e.g. if the self-healing coating forms a dent, the coating material can fill the dent without external intervention). Alternatively, self-healing can be initiated or accelerated by externally applied heat, light, electric current or other types of external stimuli.\u00a0<\/p>\n\n\n\n

When heat is used as a stimulus for the self-healing process, the display cover layer may include transparent conductors that form a heating layer in the display cover layer. The heating layer may be used to generate heat to stimulate self-healing. The heating layer may be used to generate heat in response to user input, on a predetermined schedule, or while charging the electronic device.<\/p>\n<\/blockquote>\n\n\n\n

Apple Patent: The heat approach is not new<\/h3>\n\n\n\n\n\n\n\n

This means that the user does not have to do anything. Apple has had a similar idea in the past that had to do with heat. However, it took a different approach. Heat was supposed to prevent possible damage in advance, not repair it.<\/p>\n\n\n\n

\n

To facilitate bending about the bending axis without damage when the display is cold, a portion of the display overlapping the bending axis may be selectively heated.<\/p>\n<\/blockquote>\n\n\n\n

Apple is known to be in no particular hurry to introduce new technologies. The idea of a foldable iPhone device could therefore still have to wait. However, due to the numerous patents, it can be assumed that Apple's interest in foldable products is much higher than some people think. Of course, the same applies here - a patent does not necessarily have to be implemented and can also just remain an idea. (Photo by Macrovector \/ Bigstockphoto)<\/em><\/p>\n\n\n\n
