    Abstract: Embodiments describing a method of forming a multi-layered keycap structure are disclosed herein. The method includes forming a first polymer layer on a second polymer layer, wherein the first polymer layer includes a first color and the second polymer layer includes a second color, and coupling the first polymer layer and second polymer layer to a substrate layer such that the first polymer layer is closer to the substrate than the second polymer layer. The method may further include forming a third polymer layer on the second polymer layer; and etching the multi-layered keycap structure to form an opening having a bottom surface that exposes at least one of the first or second color.

    Abstract: Some embodiments of the invention provide a method for imprinting fonts on a flexible key cap. In some embodiments, the method for imprinting font on a flexible key cap includes mixing polyurethane (PU) and one or more laser additives to form a PU clay mixture. The PU clay mixture can be infused into a molding tool to form a set of key caps. Some embodiments place a fabric layer over the molding tool and applies pressure over the fabric layer to couple the set of key caps and the fabric layer. A laser marking technique can be applied over a portion of the set of key caps. A characteristic of the portion of the set of key caps can be modified in response to the UV laser application and cause a color change at the portion of the set of key caps.

    Abstract translation: 本发明的一些实施例提供了一种在柔性钥匙盖上压印字体的方法。 在一些实施例中，用于将字体印刷在柔性钥匙盖上的方法包括混合聚氨酯（PU）和一种或多种激光添加剂以形成PU粘土混合物。 PU粘土混合物可以注入模具中以形成一组钥匙帽。 一些实施例将织物层放置在模制工具上方并且在织物层上施加压力以将该组密封帽和织物层耦合。 激光打标技术可以应用于一组键帽的一部分上。 可以响应于UV激光应用来修改该组键帽的部分的特征，并且在该组键帽的部分处引起颜色变化。

    Abstract: Embodiments of the invention are directed to a method of assembling a folio case. The method comprises molding a set of molded key caps over a flexible fabric layer to form a fabric key cap layer, where the key caps do not pass through the flexible fabric layer. The method further comprises affixing a first portion of the flexible key cap layer opposite the set of molded key caps to an interior portion of a housing, and affixing an intermediate layer between the interior portion of the housing and a second portion of the fabric key cap layer corresponding to the set of molded key caps opposite the first portion. The method further comprises attaching a first portion of a holder to the first portion of the flexible key cap layer configured to receive a computing device, wherein a second portion of the holder is not fixedly attached to the flexible key cap layer.
