Abstract:
The present disclosure relates to the display technical field, more particularly, to a pressure sensitive film and a manufacturing method thereof. The pressure sensitive film comprises a substrate, a color displaying layer and a color forming layer laminated sequentially; the other surface of the substrate opposite to the surface adjoining the color displaying layer is for bearing pressure; the color forming layer comprises at least one color forming unit, each of which comprises at least two color sacs, and the at least two color sacs have pressure-bearing thresholds different from each other, and operate when the pressure borne reaches their pressure-bearing thresholds; the color displaying layer displays corresponding colors according to the operation conditions of the color sacs, and each color corresponds to a set pressure value. The pressure sensitive film provided by the present disclosure determines a pressure range of the device according to the different colors, realizing effective monitoring of the device pressure; and determining the flatness of the device according to the evenness of the colors of tested regions, thus combining the pressure test and flatness test, so as to make the routine device pressure monitoring more convenient.
