Abstract: A display system including a display apparatus and an upgrading apparatus are provided along with a control method. A display apparatus includes an image processor which processes an image signal, a display which displays the processed image thereon, a connector to which an upgrading apparatus comprising at least one upgrading function is connected and a controller which communicates with the upgrading apparatus and controls the display to display thereon a user interface (UI) screen displaying at least one upgrading function list generated by the upgrading apparatus in response to a user selection.

Abstract: A display apparatus includes a signal receiver configured to receive an image signal, a display, and a storage configured to store a property value of the display in a first color space. The display is configured to display an image based on the received image signal and the stored property value of the display. The display apparatus further includes a controller configured to perform color calibration of the display.

Abstract: A display apparatus includes a display unit which includes a plurality of pixels having an organic light emitting diode (OLED), a power supply which supplies power to the display unit, an image processor which processes an input image to display an image on the display unit, and a controller which determines whether an average picture level (APL) of the input image is a predetermined value or more. Based on the APL value, the controller controls the image processor to compensate for a gray scale of the input image to thereby increase a brightness of the input image, and controls the power supply to reduce the power supply corresponding to the brightness increased as a result of the compensated gray scale.

Abstract: A display apparatus and a control method thereof which minimizes power consumed for driving a display unit includes a display unit which displays an image thereon; an image processor which processes an input image signal to display an image on the display unit; and a controller which determines a peripheral area which is an outer part of a main viewing area of the image for a user, and controls the image processor to display the image by reducing a brightness of the input image signal with respect to the peripheral area.

Abstract: An image display apparatus and a method of providing a high quality image are provided. The image display apparatus includes an image signal processing unit which analyzes an input image signal and outputs an average picture level (APL) and histogram information of one frame; and a controlling unit which calculates contrast control information and average signal level (ASL) information corresponding to the APL and the histogram information. The image signal processing unit enhances the contrast of the input image signal based on the contrast control information output from the controlling unit, and outputs a resulting image signal. Accordingly, a high quality image can be provided to users.

Abstract: A method and apparatus are provided for adjusting the contrast ratio in a display apparatus. The display apparatus includes a signal input module which receives a video signal and a signal processing module which processes the video signal received from the signal input module. A display module has a display panel and a panel driver for driving the display panel, and a controlling module calculates the luminance of the video signal and controls at least one of the signal processing module and the panel driver to adjust a contrast ratio of the video signal output to the display panel based on the mean of the calculated luminance.

Abstract: A display apparatus displaying an image, the display apparatus including a video signal receiver receiving a video signal comprising a sync signal, a sync delaying buffer delaying the sync signal from the video signal receiver at a predetermined interval, a logic calculator outputting a corrected sync signal by logically calculating the sync signal from the video signal receiver and the sync signal delayed by the sync delaying buffer at the predetermined interval, and a start point generator generating a sync start point on the basis of the corrected sync signal output from the logic calculator.
