Abstract:
A display apparatus includes a display panel, a first gate driver, a second gate driver, a third gate driver, and a data driver. The display apparatus is operable in a low frequency driving mode, and the low frequency driving mode includes a writing frame and a holding frame. At least one of gate power voltages used to generate a first gate signal, a second gate signal, and an emission signal has a first voltage level in the writing frame of the low frequency driving mode and a second voltage level in the holding frame of the low frequency driving mode. The data voltage is applied to the pixel in the writing frame of the low frequency driving mode. The data voltage applied to the pixel in the writing frame of the low frequency driving mode is maintained in the holding frame of the low frequency driving mode.
