Abstract
A display panel, its control methods, and a display device are provided. Conventional array MUX test circuits of display panel are reused and improved. In a target unit, there is at least one connection path between a first solder pad and a first switch that contains a second switch connected in series. An end of a touch signal line is electrically connected with a first terminal of the first switch in the connection path where the second switch is connected in series. When the display panel performs touch functions, the second switches are controlled in an off state and the data signal lines are short-circuited. Further, based on the array MUX test circuit, a driver chip sends touch signals to touch signal lines to implement touch functions. Narrow bezel designs of display panels are achieved without adding new MUX circuits.
