Abstract: Disclosed is a display device which includes a display panel that includes a plurality of pixels and includes a display area displaying an image, a panel controller that receives an external input signal from an external source and generates a control signal for dividing the display area into a first area and a second area which is disposed adjacent to the first area based on the external input signal, and an instrument module that stretches the first area and the second area of the display panel in response to the control signal. The number of the pixels per unit area in the first area is different from the number of the pixels per unit area in the second area.

Abstract: A display device includes: a display panel, which displays an image; a panel driver, which drives the display panel; and a driving controller, which controls a drive of the panel driver. The driving controller includes a compensation determination block and a data compensation block. The compensation determination block is activated after a still image is displayed for a predetermined time or more and generates a compensation value based on a final afterimage component calculated using an afterimage algorithm obtained by a combination of a first afterimage calculation equation and a second afterimage calculation equation. The data compensation block receives an image signal with respect to a target image and reflects the compensation value to the image signal to generate a compensation image signal.

Abstract: An electronic device is disclosed that includes a display panel, a data driving circuit, a scan driving circuit, and a driving controller. The driving controller generates image data based on a received image signal. The driving controller includes a minimum emission gray level determining unit that determines a gray level of the image signal, a pattern determining unit that determines a dither pattern of the image signal, a driving frequency sensing unit that determines a driving frequency of the image signal, and a data compensation unit that compensates for the image data based on the gray level and at least one of the dither pattern and the driving frequency.

Abstract: A display panel includes a plurality of pixels, data lines, gate lines, a gate driver and terminals. The plurality of pixels form a plurality of rows and columns. The plurality of data lines extend in a first direction parallel to the pixel columns. Each data line is connected to at least two adjacent pixels included in a single pixel row. The plurality of gate lines extend in a second direction parallel with the plurality of pixel rows. The gate lines each connect to at least one pixel included in a single pixel row. At least two gate lines are disposed between two adjacent pixel rows. The gate driver generates signals to drive the plurality of gate lines. The plurality of terminals receives the gate signals to transmit the gate signals to the plurality of gate lines. Some of the terminals connect with some gate lines having a cross-coupled structure.
