Abstract
A touch control unit, a touch pad, an input method and a display panel are disclosed. The touch control unit includes a substrate, a first electrode layer formed on the substrate, an electrochromic film formed on the first electrode layer, a second electrode unit formed on the electrochromic film and a piezoelectric film unit disposed corresponding to the second electrode unit. At least a portion of the piezoelectric film unit is in direct contact with the second electrode unit. The second electrode unit is transparent, and a projection area of the piezoelectric film unit on the substrate is smaller than a projection area of the second electrode unit on the substrate.
