Abstract
A display device includes a general area, an optical area that is transmissive to light, and a boundary area disposed between the general area and the optical area; a unit pixel comprising at least two pixels that are disposed in the boundary area, the at least two pixels that emits light by receiving a gate signal through a gate driving circuit in the display panel; and a timing controller that controls the gate driving circuit. At least some of the at least two pixels included in the unit pixel emit light in a high luminance state, and the remaining pixels emit light in a low luminance state, and the high luminance state or the low luminance state of the at least two pixels sequentially changes within the unit pixel according to a value of a counting signal of the timing controller.

A display device comprising:
- a display panel including a general area, an optical area configured to transmit light, and a boundary area disposed between the general area and the optical area;
- a unit pixel including at least two pixels disposed in the boundary area, the at least two pixels being configured to emit light by receiving a gate signal through a gate driving circuit in the display panel;
- and
- a timing controller configured to control the gate driving circuit,
- wherein at least some of the at least two pixels included in the unit pixel emit light in a high luminance state, and the remaining pixels emit light in a low luminance state, and
- wherein the high luminance state or the low luminance state of the at least two pixels sequentially changes within the unit pixel according to a value of a counting signal of the timing controller.
A timing controller configured to control a plurality of pixels disposed in a display panel, the pixels being configured to emit light by receiving gate signals through a gate driving circuit,
- wherein the timing controller is configured to control a unit pixel including at least two pixels disposed in the display panel,
- wherein at least some of the at least two pixels included in the unit pixel are configured to emit light in a high luminance state, and the remaining pixels are configured to emit light in a low luminance state, and
- wherein the high luminance state or the low luminance state of the at least two pixels sequentially changes within the unit pixel according to a value of a counting signal of the timing controller.
A method of driving a display device including a display panel, the method comprising:
- supplying power to the display device;
- supplying power to a timing controller and generating, by the timing controller, a start signal;
- accumulating the generated start signal in a memory disposed in the timing controller;
- initializing a gate driving circuit by supplying an initialization signal from the timing controller to the gate driving circuit;
- displaying a black screen on the display panel after initialization of the gate driving circuit;
- repeatedly performing a blank stage and a display driving stage while the display device remains powered on;
- displaying an image on the display panel after the blank stage ends;
- determining whether a power-off signal is applied from the display device;
- and
- in response to determining that the power‑off signal is applied, turning off power and stop driving the display device.
