Abstract: A flexible display device includes a flexible display panel that includes a display region, a gamma data storage that stores entire driving gamma data generated by a first multi-time programming for an entirety of the display region, and partial driving gamma data generated by a second multi-time programming for a portion of the display region, a gamma reference voltage generator that generates a gamma reference voltage based on the entire driving gamma data when the flexible display panel is not deformed, and generates the gamma reference voltage based on the partial driving gamma data when the flexible display panel is deformed, and a data driver that provides data voltages to the flexible display panel based on the gamma reference voltage.

Abstract: A display device includes a display portion, a display driver, a touch sensing portion, and a touch driver. The display portion includes data lines, scan lines, and pixels connected to the data lines and the scan lines. The display driver provides data signals to the data lines and sequentially provides scan signals to the scan lines. The touch sensing portion includes sensing electrodes. The touch driver senses a touch input based on a change of a capacitance between the sensing electrodes and calculates a movement speed of the touch input. When the movement speed of the touch input is greater than a reference speed, a first period in which the scan signals and the data signals are provided is reduced in a frame period in which a frame image is displayed.

Abstract: A method of manufacturing a display device includes: providing a glass including an edge region and an inner region; arranging a light source under the glass; setting a center position of the light source to correspond to an inside of the edge region or an inside of the inner region of the glass; directing light into the glass by using the light source; and detecting a defect in the edge region of the glass by receiving light passing through the glass by using a detection camera.
