Patent ID: 10955943

Abstract:
Embodiments enable forming a friction modified touch sensitive surface on a touch screen panel. In particular, the touch sensitive surface is augmented with two friction modifying materials that are interspersed with one another according to a predetermined pattern on the surface of the touch screen panel as a monomolecular layer. In an embodiment, The materials have indices of refraction that differ from each other by more than 0.10. In another embodiment, the materials have a kinetic coefficient of friction in one or the other range, respectively, of between 0.01 and 0.05, or between 0.06 and 0.1, said kinetic coefficients of friction being measured against printing paper that has a kinetic coefficient of friction of 0.17 with itself. In another embodiment, the materials have a water contact angle of greater than 90 degrees, and an oil contact angle of greater than 30 degrees as measured with n-hexadecane.
