Description
technical field [0001] The invention relates to a touch screen, in particular to a graphene self-inductive pressure sensor touch screen and a manufacturing method thereof. Background technique [0002] The touch input method starts from the resistive screen, and the large-scale application of the capacitive screen improves the convenience of electronic product input to a greater extent. Since the first application of capacitive screens in Apple smartphones, capacitive screens have experienced explosive development, and their market size has continued to expand. At present, due to oversupply in the capacitive screen market, product prices continue to drop, and profits continue to decrease. As a result, a large number of small-scale capacitive screen manufacturers have closed down. And whether it is a resistive screen or a capacitive screen, it is a two-dimensional input method, and we can only locate the position on the plane. Contents of the invention [0003] In view o...
