Disclosed are an embedded display screen having a touch function, terminal and touch detection method, the display screen comprising an upper substrate, a common electrode, a liquid crystal display layer and a lower substrate arranged sequentially; the common electrode is divided into multiple sub-electrodes arranged in a matrix to form a touch electrode; and a drive selector is disposed between the upper substrate and the lower substrate and is correspondingly connected to the sub-electrode via multiple conducting wires. A touch controller is disposed outside the space formed by the upper substrate and the lower substrate and is connected to the driving selector via a selection signal line and a scan signal line, the total numbers of the selection signal lines and the scan signal lines being less than that of the conducting wires; the touch controller transmits a selection signal via the selection signal line, so as to control the drive selector to select at least one of the multiple conducting wires to be conductively connected to the scan signal line. In the above method, the present invention reduces the numbers of the conducting wires needed to be led to the touch controller. |
