Sensing module which can perform proximity detection and display structure having sensing electrodes

摘要

A display includes a display module and a sensing module including a proximity sensing electrode, a set of sensing electrodes, a touch circuit, a proximity circuit and a processor. The sensing electrodes are configured to sense a touch input during a first period and sense a proximity input during a second period. The touch circuit is coupled to the sensing electrodes for controlling the sensing electrodes to sense the touch input in the first period, and converting a two-dimensional analog touch signal transmitted from the set of the sensing electrodes to a two-dimensional digital touch signal. The proximity circuit is coupled to the sensing electrodes and the proximity sensing electrode for controlling the sensing electrodes and the proximity sensing electrode to sense the proximity input, and converting a three-dimensional analog proximity signal transmitted from the set of sensing electrodes and proximity unit to a three-dimensional digital proximity signal.
