Abstract

A pressure sensing module and a pressure sensing touch control system are provided. The pressure sensing module includes a sensing layer formed on a surface of a substrate. The sensing layer includes at least one pressure sensing unit including four resistors with the same resistance values. The four resistors form a Wheatstone bridge. Pattern shapes of two of the four resistors have the same extending directions, and the two of the four resistors are not disposed adjacent to each other. The pressure sensing touch control system includes a touch control sensing unit. The touch control sensing unit is disposed between the four resistors to achieve pressure sensing and position sensing of pressing action. In the present disclosure, a bridge circuit is disposed on a single surface to prevent the sensing for pressing with a finger from being affected by temperature and other noise.
