A display device includes a display panel including first pixels arranged in a first row and second pixels arranged in a second row. A viewing angle of the first pixels is different from a viewing angle of the second pixels. The first pixels and the second pixels are disposed in a privacy region of the display panel and a public region of the display panel which is different from the privacy region. The display device further includes a panel driver configured to receive privacy region position information indicating a position of the privacy region, and drive the display panel such that the first pixels emit light in the privacy region of the display panel and the second pixels emit light in the public region of the display panel.

Display device and method of operating a display device

A display device includes a display panel including a plurality of data lines, and a plurality of pixels coupled to the plurality of data lines, a data driver including a plurality of channels providing data voltages to the plurality of pixels through the plurality of data lines, and a controller configured to control the data driver. The plurality of channels is grouped into first through N-th channel groups, where N is an integer greater than 1. The first through N-th channel groups sequentially initiate first dummy data voltage output operations in a first order from the first channel group to the N-th channel group in a first blank period before an active period, and sequentially finish second dummy data voltage output operations in a second order from the N-th channel group to the first channel group in a second blank period after the active period.

Display device, and method of operating the display device

In a method of operating a display device supporting a variable frame mode, frame data are received during a constant active period of a frame period including the active period and a variable blank period, the received frame data are written to a frame memory in the active period, the received frame data are outputted to a data driver in the active period to display an image based on the received frame data, a time of the variable blank period is counted, and, when the time of the variable blank period reaches a predetermined threshold blank time, the frame data stored in the frame memory are outputted to the data driver in the variable blank period to display an image based on the frame data stored in the frame memory.

Method of operating a display device supporting a variable frame mode, and the display device

Provided is a color compensation device of an electronic device including a first color converter, a parameter generator, an operator, and a second color converter. The first color converter receives an image signal, converts the image signal into initial tristimulus values based on a basic look-up table, and generates a conversion look-up table using the basic look-up table. The parameter generator extracts 2N number of representative parameters from the conversion look-up table and generates N number of compensation parameters on the basis of the 2N number of representative parameters. N is a natural number. The operator generates compensated tristimulus values at each gray scale using the N number of compensation parameters, generates a compensation look-up table, and converts the initial tristimulus values into the compensated tristimulus values using the compensation look-up table. The second color converter converts the compensated tristimulus values into a compensated image signal.
