Abstract
An in-cell touch panel and a display device are provided. The touch panel includes: an upper substrate and a lower substrate provided opposite to each other, a plurality of self-capacitance electrodes which are disposed between the upper substrate and the lower substrate and provided in a same layer and insulated from each other, and a touch detection chip configured to determine a touch position by detecting capacitance variation of the self-capacitance electrodes in the touch time-period. Thus, an in-cell touch panel with higher touch accuracy, lower cost, higher productivity and higher transmittance can be obtained.
