The disclosure provides a floating touch display device which includes a capacitive touch panel, a display device, an interval layer, and an optical-lens structure. The capacitive touch panel is configured to provide a floating touch surface at a floating height above a first surface. The display device includes a second surface, and the display device is configured to provide a display image from the second surface. The optical-lens structure is disposed between the capacitive touch panel and the display device. The interval layer is disposed between the second surface and the optical-lens structure, and a first optical distance is between the second surface and the optical-lens structure. The optical-lens structure is configured to image the display image on the floating touch surface at a second optical distance, and the first optical distance is equal to the second optical distance.

Floating touch display device

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.
