The present disclosure relates to a pressure sensing module, a touch panel and a method of detecting a two-point touch pressure of a touch panel. The pressure sensing module includes a substrate and a sensing layer formed over the substrate. The sensing layer includes a plurality of pressure sensing units. The pressure sensing units are axially symmetrically disposed along a symmetry axis of the substrate to form a first pressure sensing region and a second pressure sensing region. The pressure sensing unit includes four resistors having a same resistance. The four resistors are configured as a Wheatstone bridge, in which pattern shapes of two of the resistors have a same extending direction and are not adjacent. The touch panel includes the pressure sensing module described above. The method of detecting the two-point touch pressure of the touch panel is used to detect the two-point touch pressure on the touch panel.

A force sensor device, which includes a force sensing layer, is provided, in which a heat treatment layer is disposed on one side of the force sensing layer, and a thermal conductivity of the heat treatment layer is greater than or equal to 200. An OLED display device includes an OLED layer and a CPU element, in which the force sensor device is disposed between the OLED layer and the CPU element. A heat treatment layer is disposed on at least one side of the force sensor device and the force sensing layer of the OLED display device. Heat distribution is relatively uniform through the heat treatment layer, so that a temperature gradient on the force sensing layer may be effectively decreased, the temperature noise in the press force detection may be decreased, and accuracy of pressure detection may be increased.

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.
