A touch input method includes reading an (N−1)th piece of display information from a memory, where N is an integer greater than or equal to 2; acquiring an Nth piece of coordinate information in an Nth coordinate acquiring period, where the coordinate information is used to indicate location information, of a user touch, sensed by a touch component, and the coordinate acquiring period is less than a refresh period of a display component; generating, using the (N−1)th piece of display information and the Nth piece of coordinate information, an Nth piece of display information corresponding to the Nth coordinate acquiring period, and storing the Nth piece of display information in the memory; and when the display component is refreshed, displaying, using the display component, latest display information stored in the memory.
