The use of display devices as an HMI (Human Machine Interface) tool to establish interactive connections between people and machines has been around for a while, and it continues to grow.
This tendency is also evident in automobile interiors, where a growing quantity of information is shown, ranging from entertainment information to crucial information for safe driving. This trend is only expected to grow in the future.

White light's quality
With white LED backlight light flowing through the LCD's color filter (the three fundamental colors of light: R for red, G for green, and B for blue), the LCD (Liquid Crystal Display) screen of a meter or entertainment system is a full-color display.The light source utilized for the backlight alters the display quality and power consumption characteristics, even if the LCD is the same.

Variation in the Quality of the Light
When the backlight's white light passes through the LCD and color filter, it appears as a color picture.

Structure of the LCD backlight
Light from the LCD's back is sent via the backlight to reveal the LCD as a luminous display.Two common layouts for LEDs-the light source for the backlight in automotive applications-are described here.

LED Product Line for LCD Backlights
Both edge-lit and direct-lit backlights may be used with our LED light sources.
Depending on the application and requirements, the right light source may be chosen.
