A method of aging a display device includes: inputting a display device including a plurality of pixels into an aging chamber, reaching a preset condition of the display device, sensing each of the plurality of pixels, compensating each of the plurality of pixels, and aging the display device.

Method of aging a display device

A display apparatus includes pixel areas and a light blocking area between the pixel areas. The display apparatus includes a first base substrate, a thin film transistor, and first, second, and third color filters. The first color filter has a first color, the second color filter has a second color different from the first color, and the third color filter has a third color different from the first and second colors. In the light blocking area, the thin film transistor, the first color filter, and the third color filter at least partially overlap each other. The second color filter in at least one pixel area is connected to an adjacent second color filter disposed in an adjacent pixel area by a bridge portion, and the bridge portion is formed of the same material as the second color filter and is disposed in the light blocking area.

A driving method of a display device is disclosed. According to one aspect, the method includes applying a first voltage of a predetermined level to an anode of a plurality of organic light emitting diodes (OLEDs) included in a plurality of pixels. A plurality of driving transistors are driven to be connected to the plurality of OLEDs. The method further includes transmitting a first power source voltage of a logic high level to the anode of the plurality of OLEDs as a threshold voltage to compensate a threshold voltage of the plurality of driving transistors, and applying a data voltage to a plurality of pixels as a data writing step turning on a plurality of driving transistors. The second power source voltage applied to the cathode of the plurality of OLEDs is changed to a second voltage of the logic low level in a state in which a plurality of driving transistors are turned on. In the turned on state, light is emitted from the plurality of OLEDs.

A light emitting display is configured to reduce or prevent motion blur by shortening a time that a black frame is displayed between image frames. One embodiment includes display region, a data driver, a scan driver, and a controller. The display region displays frames of images according to a data signal and a scan signal. The data driver transmits data for displaying first frames and second (black) frames between the first frames. The scan driver includes first and second scan driving circuits for transmitting scan signals, and a switch unit for selectively coupling the first and second scan driving circuits. The scan driver transmits scan signals sequentially during the first frames and transmits scan signals to at least two of the scan lines concurrently by driving the first and second scan driving circuits in parallel during the second frames. The controller transmits a driving control signal to control the switch.
