Patent ID: 7505025

Claim:
An arrangement comprising: a panel of a flat screen, a graphics processor to which a digitized image signal is applied, a lookup table configured to evaluate the digitized image signal and transmit the signal to the panel via an interface, whereby image information from the signal is displayed on the panel of the flat screen, wherein, during a calibration phase, a test image is displayed on the panel of the flat screen and a luminance of the test image is measured by a sensor, and the sensor for measuring the luminance of the test image on the panel is arranged in a standby position in an area of the flat screen that is not visible to a viewer, further comprising a pivoting device carrying the sensor to attach the sensor to the flat screen and to pivot the sensor substantially parallel to the panel from the standby position into a position for measuring the luminance of the test image on the panel, and wherein the graphics processor adjusts the lookup table as a function of the measured luminance.
