A display device including: a display panel including a plurality of pixels; a data driver configured to provide data voltages to the plurality of pixels; and a controller configured to control the data driver, to detect a same data region of the display panel when first image data in a current frame period is the same as second image data in a previous frame period, and not to transfer the first image data to the data driver in the current frame period.

Electronic device including a display device for not transmitting image data during periods having same data and method thereof

A data driving circuit includes: a reference voltage generator that receives a data control signal and generates a gamma reference voltage and a test reference voltage, a data driving unit that outputs a data signal for a pixel based on the gamma reference voltage, and an output circuit that outputs a test data voltage for a dummy pixel based on the test reference voltage.

Data driving circuit, display device including the same, and operating method of display device

Display device and a method of operating the display device

A display device includes: a display panel, a data driver, and a scan driver. The data driver outputs data signals during a writing frame and outputs a bias voltage during a holding frame. The data driver includes a plurality of driving chips, and each of the driving chips includes: a gamma voltage generator, a data converter, a main output part for outputting corresponding data signals of the data signals during the writing frame, and a sub-output part for outputting the bias voltage during the holding frame. The gamma voltage generator of a selected driving chip among the plurality of driving chips is electrically connected to the sub-output parts disposed in the plurality of driving chips, respectively.
