Abstract: An image display system includes a camera part and an image display part. The image display part includes a user analyzer, a gamma corrector, a gamma voltage generator, and a display panel. The camera part takes a picture of a user and generates a user image signal. The user analyzer calculates the user's viewing direction based on the user image signal. The gamma corrector generates a correction gamma value based on the viewing direction. The gamma voltage generator generates a gamma voltage based on the correction gamma value, and the display panel displays an image corresponding to the gamma voltage. Accordingly, the image display system provides the image having an optimized gamma curve to the user in real time even without a separate input from the user.

Abstract: A display apparatus includes a plurality of display panels, a power voltage generator and a driving controller. The power voltage generator generates power voltages of the plurality of display panels. The driving controller receives the power voltages from feedback points of the plurality of display panels and generates a control signal and controls levels of the power voltages based on fed-back power voltages from the feedback points of the plurality of display panels. The power voltage generator adjusts the levels of the power voltages and generates compensation power voltages based on the control signal.

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.
