Arrangement Comprising a Mobile Telephone and an LCD Display Module

An arrangement, comprising:

• an LCD display module comprising a wireless communication interface, an LCD display and a look-up table via which a luminance characteristic curve of the LCD display is adjusted to a reference luminance characteristic curve during a calibration phase;
• and
• a mobile telephone comprising a wireless communication interface and a processor for executing a calibration program,
• wherein the LCD display module transmits recorded luminaces to the mobile telephone, the mobile telephone uses the luminances to compute video output values via the calibration program, the mobile telephone transmits the computed video output values to the LCD display module to be loaded in the look-up table.

A method for an on site calibration of a medical device having a LCD display module, comprising:

• transmitting recorded luminaces via a wireless communication interface of the medical device to a wireless communication interface of a mobile telephone;
• computing video output values using the transmitted luminaces;
• and
• transmitting the video output values from the mobile telephone to the medical device;
• and
• loading the transmitted video output values into a look-up table in the LCD display module for selecting a test pattern from a test image,
• wherein the test image is stored or generated via the LCD display module,
• whereby the LCD display module is calibrated on site of the medical device.
