Abstract
A display device includes: an optical sensing array to detect light; a backlight to emit light toward a surface of the display device; and a thin optical film layer at the surface of the display device, the thin optical film layer being configured to, while a first shear force is being applied at a first point of contact at the surface of the display device, reflect light having a first wavelength at a front area ahead of the first point of contact in a direction of the first shear force, and reflect light having a second wavelength at a back area behind the first point of contact opposite the front area, the first wavelength being different from the second wavelength.
