  • Patent number: 12626656
    Abstract: A driving process of the display panel includes a first stage, a display stage, and a second stage. The driving method of the display panel includes the following steps. A first voltage is started to be provided to the metal pattern at the first time in the first stage, where the first voltage is greater than 0. A first black-state voltage is started to be provided to the data line at the second time in the first stage. A second voltage is stopped to be provided to the metal pattern at the third time in the second stage, where the second voltage is greater than 0. A second black-state voltage is stopped to be provided to the data line at the fourth time in the second stage. The first time is before the second time, and/or the third time is after the fourth time.
