Problems solved by technology

For in-cell touch screens, the touch drive electrodes and touch sense electrodes are integrated in the display screen, and there is a parasitic capacitance between the touch drive electrodes, touch sense electrodes and other functional electrodes. Similarly, the parasitic capacitance reduces the sensitivity of touch point positioning.

Description

technical field [0001] The invention relates to the technical field of touch display, in particular to a touch screen, a manufacturing method thereof, and a display device. Background technique [0002] With the development of display technology, touch display has drawn more and more attention from people. As an output device of a display device, a touch screen has gradually become a mainstream in the display field. [0003] Existing touch screens mainly include resistive touch screens and capacitive touch screens according to their working principles. Resistive touch screens are not sensitive enough. The sensitivity of the capacitive touch screen is higher than that of the resistive touch screen and can realize multi-touch. However, as people's demand for high-quality touch screens continues to increase, the sensitivity of the touch screen needs to be further improved. [0004] The following briefly introduces the structure and working principle of the existing capaciti...
