A touch screen and a touch point positioning method are disclosed. The touch screen comprises a display panel and a touch point positioning device, the touch point positioning device comprises a timing unit, a calculating unit and n receiving units, the receiving units are provided in edge areas of the display panel, the receiving units are connected with the timing unit, and the timing unit is connected with the calculating unit. According to technical solutions of the present invention, the receiving units receive an acoustic wave signal generated at a touch point when the display panel is touched, the timing unit records reception times when the receiving units receive the acoustic wave signal, and the calculating unit calculates a position coordinate of the touch point on the display panel according to the reception times of the receiving units recorded by the timing unit, thus achieving positioning of the touch point.

A supplemental surface area allows gesture recognition on outer surfaces of mobile devices. Inputs may be made without visual observance of display devices. Gesture control on outer surfaces permits socially acceptable, inconspicuous interactions without overt manipulation.

The present invention provides an ultrasonic fingerprint recognition module and a display panel. Advantages of the present invention are that a vibration absorbing layer can absorb mechanical energy of a piezoelectric thin film layer such that a number of cycles of later ultrasound is significantly reduces to extremely increase a vertical resolution of ultrasound fingerprint recognition and overall recognition effect and precision.

An actuator for controlling the operation of an apparatus comprises a panel (16) and an acoustic sensor (26). The panel provides a partition within a building structure, while the acoustic sensor is adapted to detect acoustic waves propagating through the panel. When a user exerts pressure against the panel, the sensor detects the acoustic waves that are formed and emits signals for controlling the operation of an apparatus, such as a doorbell, a light source, a television, a sound system, a ventilation system, a window blind, a radio or an alarm.
