This application relates to the field of electrical engineering, specifically to touchscreens. A long-distance touchscreen film based on a tip discharge mechanism includes a touch film having a dielectric layer as a substrate and electrode arrays arranged on both sides of the dielectric layer, namely a first electrode array and a second electrode array, and a plastic substrate. At least two sets of tip discharge arrays, namely a first tip discharge array and a second tip discharge array, are embedded in the plastic substrate. Each tip discharge array includes at least two tip discharge electrodes, each having a large end and a small end. The small end of the tip discharge electrode is located in the direction away from the dielectric layer on the plastic substrate. The capacitive touchscreen optimizes touch sensitivity by using a plastic substrate and tip discharge arrays, enabling the capacitive touchscreen system to detect weak capacitance changes when a finger or conductor approaches but does not directly contact the screen, supporting hover touch when the finger is not in contact with the screen.
