A display device includes a driving frequency calculator configured to divide output image data into central, intermediate, and peripheral images respectively corresponding to central, intermediate, and peripheral visual field regions, calculate spatial frequencies of the central image, the intermediate image, and the peripheral image, calculate critical flicker frequencies of the central visual field region, the intermediate visual field region, and the peripheral visual field region based on the spatial frequencies and based on viewing angles of the central visual field region, the intermediate visual field region, and the peripheral visual field region, and determine driving frequencies of the central visual field region, the intermediate visual field region, and the peripheral visual field region based on the critical flicker frequencies, and a display panel configured to display an image based on the output image data and based on the driving frequencies.

Display device, method for driving the same, and head-mounted display apparatus

A pixel includes a light-emitting element, a driving switching element and a noise switching element. The driving switching element applies a driving current to the light-emitting element. The noise switching element outputs a noise signal having a noise frequency to an input electrode of the driving switching element in response to a noise control signal. The noise frequency is equal to or greater than a driving frequency of the pixel. The noise signal having a periodicity is applied to the input electrode of the driving switching element of the pixel.

Pixel, display apparatus including the same and method of driving the display apparatus

An electronic device includes a display panel, a data driving circuit, a scan driving circuit, and a signal control circuit that receives input data. The signal control circuit includes a histogram check unit that divides data of one frame among the input data into a plurality of regions based on a gray scale and calculates a distribution of the data based on the plurality of regions, a gray check unit that calculates the number of major grayscales having data of a specific number or more among the input data, an optical waveform analysis unit that generates a signal calculated based on an optical waveform of the plurality of pixels, and a frequency selection unit that selects a driving frequency of the display panel based on the distribution of the data, the number of the major grayscales, and the signal.

Electronic device and driving method of electronic device

A method and an apparatus for operating a User Interface (UI) of a conference call terminal are provided. The method includes operating a first camera and a second camera when a conference call is initiated, outputting an output image of a conference call screen comprising a first image and a second image collected from the first camera and the second camera, the first image and the second image being arranged not to overlap, and distinguishing a speaking person's image from another person's image, when the speaking person's image is detected in the output image of the conference call screen.
