A display apparatus includes: a display panel including a plurality of pixels and a panel driver for applying a data voltage to pixels by the same pixel-column and performing a sensing operation, which senses the pixels receiving the data voltage. The plurality of pixels include first pixels having a first color and second pixels having a second color different from the first color. After the sensing operation is performed on a first odd-numbered group of the first pixels, the sensing operation is performed on a first even-numbered group of the first pixels. After the sensing operation is performed on the first even-numbered group of the first pixels, the sensing operation is performed on a second odd-numbered group of the second pixels. After the sensing operation is performed on the second odd-numbered group, the sensing operation is performed on a second even-numbered group of the second pixels.

Display apparatus and method of driving the display apparatus

A display device is disclosed that includes a display panel including a plurality of pixels, a printed circuit board connected to the display panel, a temperature sensor disposed on the printed circuit board, a flexible circuit board that connects the display panel to the printed circuit board, a data driver disposed on the flexible circuit board, and a temperature sensing part disposed on the printed circuit board. The flexible circuit board is bent such that the printed circuit board is disposed under the display panel and the temperature sensor is disposed adjacent to a sensing pixel outputting a sensing current among the pixels.

Display device including sensing pixel on display panel and temperature sensor on printed circuit board, and driving method thereof

Disclosed is a display device including a first output part, a second output part, a power supply circuit connected to input terminals of the first output part and the second output part, a first sensing part connected to an output terminal of the first output part, a second sensing part connected to an output terminal of the second output part, a first voltage output terminal connected to the first sensing part and the second sensing part, a plurality of pixels connected to the first voltage output terminal and configured to display an image, and a defect determination part controlling shutdown of the power supply circuit by comparing a first sensing value and a second sensing value, which are received from the first sensing part and the second sensing part, with a first reference value and a second reference value having a level lower than the first reference value.

Display device and driving method thereof

A method of operating a display device includes: receiving image data at an input frame frequency; generating a modulated clock signal by modulating an input clock signal according to a modulation frequency; randomly selecting an output frame frequency within a data frequency selection range, the input frame frequency being within the data frequency selection range; determining an output start timing of the image data based on the output frame frequency; initiating, at the output start timing, output of the image data in synchronization with the modulated clock signal; and displaying an image based on the outputted image data.
