Abstract
An in-cell touch panel and a display device are disclosed. In the in-cell touch panel, the data line is multiplexed as a connection line for electrically connecting the self-capacitance electrode to the touch detection chip. During a display period, the first control component is used to control each self-capacitance electrode to be disconnected from a corresponding connection line, and the second control component is used to control each data line to be electrically connected to the data driving circuit. During a touch period, the first control component is used to control each self-capacitance electrode to be connected to a corresponding connection line, and the second control component is used to control the data lines multiplexed as the connection lines to be electrically connected to the touch detection chip.
