  • TOUCH-INPUT DISPLAY DEVICES WITH FORCE MEASUREMENT USING PIEZOELECTRIC PILLARS
    Publication number: 20180032180
    Abstract: A touch-input display device includes a substrate, piezoelectric pillars that are on and extend away from a surface of the substrate, and light emitter devices each coupled to a different one of the piezoelectric pillars. The substrate has power lines and signal lines. The piezoelectric pillars are electrically isolated from each other, and each of the piezoelectric pillars includes a piezoelectric material that generates an electric voltage across a pair of the signal lines responsive to an applied touch force compressing the piezoelectric pillar. The light emitter devices are each electrically connected to a pair of the power lines.
