  • Display device and method for driving the same
    Patent number: 11915639
    Abstract: A display panel of a display device is divided into a first display region and a second display region. The second display region includes a boundary region adjacent to the first display region and a non-boundary region opposite to the first display region with respect to the boundary region. The driving controller outputs the voltage control signal, such that the first voltage in a first high voltage level and the second voltage in a first low voltage level are generated when the first display region is driven. The driving controller outputs the voltage control signal, such that the first voltage in a second high voltage level lower than the first high voltage level and the second voltage in a second low voltage level higher than the first low voltage level are generated, when the non-boundary region of the second display region is driven.
