Abstract: A display apparatus includes a display panel, a panel driver, a touch driving output layer of a touch panel and touch driver. The display driver outputs a panel driving signal to the display panel. The touch driver outputs a touch driving signal to the touch driving signal output layer. The display apparatus determines a driving frequency of the display panel according to the panel driving signal and synchronizes a frequency of the touch driving signal with the driving frequency.

Abstract: A display panel includes a circuit layer including first, second, and third intermediate insulating layers, first and second conductive patterns, and a light emitting element layer disposed on the circuit layer, and including first and second light emitting elements in a first area and a second area of a base layer. The first light emitting element is electrically connected to one of the first conductive patterns through a first through-hole formed through the second intermediate insulating layer and the third intermediate insulating layer. The second light emitting element is electrically connected to one of the second conductive patterns through a second through-hole formed through the third intermediate insulating layer. A smallest width of the first through-hole and a smallest width of the second through-hole are substantially equal in a cross-section.

Abstract: A display device includes a display panel including a first display area, and a second display area adjacent to the first display area, and a panel driver overlapping the second display area of the display panel. The display panel further includes light emitting reference units each including light emitting elements and being disposed in the second display area, and driving reference units each including driving circuits and being electrically connected to a corresponding light emitting reference unit among the light emitting reference units. An arrangement order of the light emitting reference units is different from an arrangement order of the driving reference units corresponding to the light emitting reference units.
