A display device includes a display panel including a plurality of pixels, and a panel driver configured to drive the display panel. At least one pixel of the plurality of pixels includes a first light emitting element having a first viewing angle, a second light emitting element having a second viewing angle different from the first viewing angle, a pixel circuit configured to generate a driving current, a first transistor configured to provide the driving current to the first light emitting element in response to a first signal, and a second transistor configured to provide the driving current to the second light emitting element in response to a second signal. In response to a mode switching signal, the panel driver gradually changes an on-period ratio of at least one of the first signal and the second signal over a plurality of frame periods.

Display device and method of operating a display device

A display device includes: a display panel including a pixel connected to a scan line and a data line; a flexible printed circuit board connected to the display panel; a lightning test circuit on the flexible printed circuit board and connected to the data line; and a plurality of resistors adjacent to opposite sides of the lightning test circuit and connected to the lightning test circuit.

Display device

A display device includes: a substrate including a display area, a peripheral area surrounding the display area, a hole area positioned inside the display area, and a pad area; a crack detection line including a first part in the pad area and extending to the peripheral area and a second part connected to the first part, disposed to surround the hole area, and extending to the pad area; a printed circuit board in the pad area; first transistors in the pad area and connected in series between the printed circuit board and the first part, where each of gate electrodes of the first transistors is connected to a first signal line; and second transistors in the pad area and connected in series between a constant voltage line and the first part, where each of gate electrodes of the second transistors is connected to a second signal line.

A display apparatus includes a plurality of pixels arranged in rows and columns, a plurality of gate lines in a first direction and connected to the pixels, and a plurality of data lines connected to the pixels. A number of data lines are between pixels in one row and in each of first areas adjacent to one side of the pixels in one column of a first column and the last column.
