The quality of white light

The LCD (Liquid Crystal Display) screen of a meter or entertainment system is a full-color display, with white LED backlight light passing through the LCD's color filter (the three primary colors of light: R: red, G: green, and B: blue).Even if the display device (LCD) is the same, the light source used for the backlight changes the display quality and power consumption characteristics.

Difference in Light Quality

White light from the backlight can be seen as a color image by passing through the LCD and color filter.

LCD backlight structure

LCDs are made visible as a luminescent display by transmitting light from the back of the LCD through the backlight.　The following describes two typical layout for LEDs, which are the light source of the backlight, used in automotive applications.
