    Abstract: A display device includes a display panel which displays an image during a plurality of driving frames, a panel driver which drives the display panel, and a driving controller which controls a driving operation of the panel driver. The driving controller divides the display panel into a first display area and a second display area based on an image signal. Each of the plurality of driving frames includes a full frame in which the first display area and the second display area are driven, and a plurality of partial frames in which only the first display area is driven. A number of the plurality of partial frames included in each of the plurality of driving frames is changed.

    Abstract: A driving controller divides a display panel into first and second display areas according to an operation mode, outputs a start signal indicating a start of one frame and a masking signal for indicating a start of the second display area, sets a basic driving frequency to a normal frequency when the operation mode is a normal frequency mode, sets the basic driving frequency to a frequency lower than the normal frequency when the operation mode is a multi-frequency mode, and outputs the start signal and the masking signal. The first display area operates at a first driving frequency and the second display area operates at a second driving frequency, and the scan driving circuit sequentially drives scan lines in synchronization with the start signal, and stops, in response to the masking signal, driving of some of the scan lines corresponding to the second display area.

    Abstract: An electronic device includes a display panel which includes a plurality of pixels and displays an image at each of multiple frames, a driving circuit which drives the multiple frames at multiple operating frequencies, a voltage generator which provides a voltage to the display panel, and a drive controller. The drive controller includes a representative frequency calculator which calculates a representative frequency, based on operating frequencies of ‘n’ number of frames before one frame of the multiple frames, and a compensating signal calculator which outputs a compensating signal, based on the representative frequency and a count number in the one frame. The drive controller transmits the compensating signal to the voltage generator, the voltage includes a reference voltage, the voltage generator generates the reference voltage based on the compensating signal, and the voltage generator provides the reference voltage to each of the plurality of pixels.

    Abstract: A display apparatus includes a display panel, a gate driver, a data driver and an emission driver. The display panel includes a pixel. The gate driver is configured to output a gate signal to the pixel. The data driver is configured to output a data voltage to the pixel. The emission driver is configured to output an emission signal to the pixel. The pixel includes a light emitting element, a driving switching element configured to apply a driving current to the light emitting element and a bias switching element configured to apply a bias voltage to the driving switching element. The display apparatus increases a level of the bias voltage when a duration of a light emission time of the pixel is increased.

    Abstract: A display apparatus includes a display panel and a display driver. The display panel has a first pixel structure. The display driver is configured to receive input image data including first data, and generate a driving signal for driving the display panel based on conversion data. The display driver includes a converter configured to convert the first data into the conversion data. The conversion data include conversion data in N rows and M columns. Each of (2K−1)-th column conversion data include first color conversion data representing a first color and second color conversion data representing a second color. Each of 2K-th column conversion data include third color conversion data representing a third color and fourth color conversion data representing the second color. N, M and K are positive integers.
