How to choose a right display – color temperature

The color temperature of a light source is the temperature of an ideal black-body radiator that radiates light of comparable color to that of the light source. Color temperature is conventionally expressed in kelvins, using the symbol K, a unit of measure for absolute temperature.

Take the iron as an example, we may understand that as the temperature goes higher, the color of the iron will go to red, yellow, and white. Color temperatures over 5000 K are called cool colors (bluish white), while lower color temperatures (2700–3000 K) are called warm colors (yellowish white through red).

When we find image colors don’t match or have differences with the original materials on the screen, the images are seriously distorted, which is associated with color temperature of white balance on LED display. If people watch the display screen directly, the color temperature of white balance between 6500k and 8000k is ok, and if the display is used for broadcasting, the color temperature should be 5500k so that to present an authentic image through the video cameras.

But 5500k may not a be suitable for people live in different latitude. Normally the higher the latitude is, the color temperature that human eyes feel comfortable might be higher. For example, for a display, it is better to set the color temperature of the display that will be installed in Stockholm to 7200k; and to set the color temperature of the display that will be installed in Manila to 5500k.
