Abstract: An electronic device, including a touch recognition unit; a display unit receiving a signal from the touch recognition unit; a fingerprint recognition unit receiving a signal from the display unit. A processor is configured to transmit and receive a signal to/from the touch recognition unit, the display unit, and the fingerprint recognition unit. The processor may remain in an inactive state while the touch recognition unit, display unit, and fingerprint recognition unit are activated. The processor is activated when a preset user's fingerprint input is provided. A method operates the electronic device.

Abstract: A display module includes: a display panel including a display area for displaying an image; a lens unit disposed on the display area; an image generator for receiving visual sensing data from the outside by sensing an eye of a user, identifying a reference area on the display area, based on parameter data and the visual sensing data, and generating a converted image by adjusting grayscales of a target area adjacent to the reference area in an input image; and a controller for controlling the display panel, based on the converted image. The image generator determines a size of the reference area according to the parameter data.

Abstract: An organic light emitting display device includes a data driver, a pixel unit, a timing controller, and a power generator. The data driver generates data signals to be supplied to data lines based on gamma voltages. The pixel unit controls the amount of current flowing from a first power supply to a second power supply in each of a plurality of pixels based on the data signals and a reference power voltage. The timing controller limits the maximum brightness of the pixel unit corresponding to a plurality of dimming levels. The first power generator changes the voltage of the first power supply corresponding to the dimming levels.
