The light that backlights the display is called backlight. Two points play a central role in ensuring that the lighting is optimal.
The first and most important point is brightness. Since around 90 percent of the light is absorbed by LCDs, polarisation foils or other components, sufficiently bright LEDs are needed. However, compromises have to be made: Because with higher brightness, the power consumption also increases and thus the power consumption.
The second point is the colour of the backlight. In some cases, coloured LEDs, for example red or blue, are used. In most cases, however, they are white LEDs.
But watch out! Not all white is the same. A distinction is made here between:
- Warm white (below 3’300 K) rather yellowish to reddish hue.
- Neutral white (3’300 to 5’300 K)
- Cold white (above 5’300 K) rather bluish hue
Depending on the use of the display, our display experts decide which brightness is optimal and which colour is most suitable. Would you like to know more? We will be happy to advise you.
