[0050] A touch screen is an inductive liquid crystal display system that can receive input signals from a contact. The touch screen can be a touch panel on a device such as a mobile phone, a palmtop computer, or a tablet computer. The contact can refer to an object such as a user's finger or a stylus. Find the contact position of the contact on the display screen by scanning the touch screen, and execute the corresponding command according to the information of the contact position. Such as figure 1 As shown, the surface of the touch screen 100 has row sensing lines 101 parallel to each other and column sensing lines 102 parallel to each other. Generally speaking, the row sensing lines 101 and column sensing lines 102 are perpendicular to each other, and the row sensing lines 101 and the column sensing lines are at the intersection position. The sensing lines 102 are insulated from each other, and the finger in the figure indicates the position and area where the contact touch...
