Abstract:
The present invention provides a pressure sensing panel, which includes a carrying substrate, a gas cell layer formed on the carrying substrate and a gas pressure sensor, wherein the gas cell layer includes at least one gas cell, a predetermined amount of gas is sealed in each gas cell, and at least one gas pressure sensor is provided inside each gas cell. The present invention further provides a display device, a method for fabricating the pressure sensing panel and a force touch method using the display device. In the present invention, deformation of the gas cell is physical deformation, which is hardly affected by the surroundings, so the level of force applied to the display device can be determined accurately by using the pressure sensing panel provided by the present invention, and further, operation can be performed accurately.
