Abstract
A display device includes: a pixel array including a plurality of pixels; a plurality of infrared (IR) emitters to emit IR light towards a surface of the display device; a plurality of IR detectors to detect IR light; a deformable layer on the pixels, on the IR emitters, on the IR detectors, and at the surface of the display device; and a plurality of tracers at the deformable layer to reflect the IR light emitted by the IR emitters towards the IR detectors and to, while a shear force is being applied at a point of contact at the surface of the display device, shift ones of the tracers around the point of contact in a direction of the shear force such that IR reflectance at the surface of the display device is changed.
