Provided in the present invention are an embedded touch screen and a driving method therefor. The embedded touch screen comprises a first substrate and a first electrode layer arranged on the first substrate. The first electrode layer comprises multiple touch driver electrodes, touch induction electrodes, and touch amplification electrodes that are insulated from each other. The touch amplification electrodes are arranged at gap areas between the touch driver electrodes and the touch induction electrodes. At a display stage, a common voltage is applied to at least the touch driver electrodes and the touch induction electrodes. At a touch stage, a touch drive signal is applied to the touch driver electrodes. The touch induction electrodes output touch induction signals. By arranging the touch amplification electrodes and by switchover of respective functions of the touch amplification electrodes via a switchover control unit respectively when displaying and when touched, the embedded touch screen not only ensures normal display of the embedded touch screen, but also increases the touch sensitivity and linearity of the embedded touch screen. |
