Abstract: The present disclosure relates to a display apparatus enhancing a display quality and a method of driving the display apparatus. The display apparatus comprises a display panel and a power voltage generator. The display panel comprises a plurality of pixels. The power voltage generator is configured to output a first initialization voltage, a second initialization voltage, a first power voltage, and a second power voltage less than the first power voltage to the plurality of pixels. The power voltage generator is configured to output the second initialization voltage substantially equal to the second power voltage in response to an emergency shutdown signal.

Abstract: A display includes: pixels arranged in a display area (DA) in a first direction (FD) and a second direction (SD), each pixel to display one of first to third colors; gate lines (GLs) extending in the FD in the DA, arranged in the SD, and connected to the pixels; a stage unit (SU) in a non-DA, the SU including stages and being connected to the GLs; clock lines (CLs) to receive signals to control the SU, the CLs extending in the SD in the non-DA and being arranged in the FD; and bridge lines connecting the CLs with the SU. First and second CLs are connected to stages connected to pixels to display the first color. Third and fourth CLs are connected to stages connected to pixels to display the second color. Fifth and sixth CLs are connected to stages connected to pixels to display the third color.
