In-cell touch panel and display device
An in-cell touch panel and a display device are disclosed. The in-cell touch panel includes: an array substrate provided with top-gate thin-film transistors (TFTs); a plurality of mutually independent self-capacitance electrodes arranged in a same layer and disposed on a layer provided with the top-gate TFTs; a touch detection chip configured to determine a touch position in a touch period; and a plurality of wirings disposed beneath the layer provided with the top-gate TFTs and configured to connect the self-capacitance electrodes to the touch detection chip. Orthographic projections of patterns of the wirings on the array substrate shield patterns of active layers of the top-gate TFTs. The in-cell touch panel can reduce the manufacturing cost and improve the productivity.
