Abstract: A display apparatus includes an integral integrated circuit and a display panel. The integral integrated circuit includes a gate channel which outputs a gate primitive signal and a data channel which outputs a data voltage. The display panel includes a level shifter which amplifies the gate primitive signal to generate a gate signal. The display panel is configured to display an image based on the gate signal and the data voltage. The display panel includes a first gate line extending in a first direction and a second gate line extending in a second direction. The second direction is different from the first direction. The second gate line is connected to the first gate line. The level shifter is connected to the second gate line.

Abstract: A display apparatus includes a display panel, a first coordinate calculator, a second coordinate calculator and a gamma setter. The display panel includes a first display area and a second display area. The first coordinate calculator is configured to calculate color coordinates of first image data of the first display area. The second coordinate calculator is configured to calculate color coordinates of second image data of the second display area. The gamma setter is configured to adjust luminance of the first image data, the color coordinates of the first image data, luminance of the second image data and the color coordinates of the second image data.

Abstract: A display device includes a display panel configured to be driven in an initial mode or in a main mode; an input sensing part on the display panel and configured to be driven in a mutual sensing mode or in a self-sensing mode; a fingerprint sensing part below the display panel; and a control module configured to control operations of the display panel, the input sensing part, and the fingerprint sensing part. The display panel is between the fingerprint sensing part and the input sensing part. When the display panel is driven in the initial mode, the control module drives the input sensing part in the self-sensing mode and controls the fingerprint sensing part to detect a fingerprint touched on the input sensing part.
