Display system

A display system (1) comprising at least one screen (2) located at an air and/or space vehicle, and allowing flight data and/or control indicators to be displayed thereon, wherein a day mode or a night mode is created on the screen (2) at a predetermined wavelength value;

• at least one programmable logic tool (3) located in connection with the screen (2), enabling the flight data to be displayed on the screen (2) in the day mode or the night mode when the user switches to the day mode or the night mode, and enabling the wavelength values of the pixels on the screen (2) to be determined in the RGB color space, wherein the programmable logic tool (3) which converts the RGB color space wavelength values into wavelength values in the CIE 1976 UCS color space when switching to the night mode by the user, and calculates an average of the converted wavelength values and the wavelength values in the a reference CIE 1976 UCS color space predetermined by a display system manufacturer, so that the converted pixel wavelength values in CIE 1976 UCS color space are brought to the reference CIE 1976 UCS color space wavelength value range, and the brought pixel wavelength values are converted back to wavelength values in RGB color space to be reflected on the display in the night mode coordinates.
