摘要： A display panel includes a first display area and a second display area. The display panel includes a plurality of first pixel groups in the first display area, a plurality of second pixel groups in the second display area, and a plurality of scan lines connected to the first and second pixel groups. The second display area includes a plurality of light emitting areas in which the second pixel groups are respectively disposed, and a plurality of open areas in which the second pixel groups are not disposed. One of a second pixel group of an n-th row is cut and does not overlap an adjacent open area of the n-th row, and is connected in the second display area to a scan line of a second pixel group of an (n−1)-th row or a scan line of a second pixel group of an (n+1)-th row.

摘要： A display apparatus includes a display panel, a gate driver, a data driver and an emission driver. The display panel includes a pixel. The gate driver is configured to provide a gate signal to the pixel. The data driver is configured to provide a data voltage to the pixel. The emission driver is configured to provide an emission signal to the pixel. The pixel includes a light emitting element, a driving switching element and a bias switching element. The driving switching element is configured to apply a driving current to the light emitting element. The bias switching element is configured to provide a bias voltage to an input electrode of the driving switching element. A frequency of a bias gate signal applied to a control electrode of the bias switching element is greater than a frequency of a data write gate signal applied to the pixel.
