Latest Patents

One of Zhaoyang Han's latest patents is for a multi-layer keycap. This invention describes a method of forming a multi-layered keycap structure, which includes a first polymer layer on a second polymer layer. The first polymer layer features a distinct color, while the second polymer layer has a different color. The design allows for the first polymer layer to be closer to the substrate than the second polymer layer. Additionally, the method may involve forming a third polymer layer and etching the structure to create an opening that reveals at least one of the colors.

Another significant patent is for a touch surface designed for electronic devices. This invention provides a touch surface that can be integrated into devices, allowing user input through various means such as touchscreens or keycaps. The touch surface consists of a substrate, a rigid layer to maintain its shape, and a surface layer that adjusts the surface energy. The materials used include plastic for the substrate, a diamond-like carbon (DLC) coating for the rigid layer, and fluoro- or silicon-rich molecules for the surface layer. This construction aims to enhance the durability of the touch surface against wear and repeated use.
