LED Display/LED Backlight

LED backlight is the most popular backlighting for small and medium LCDs. The advantages of LED backlighting are its low cost, long life, immunity to vibration, low operational voltage, and precise control over its intensity. The main drawback is it does require more power than most of the other methods, and this is a major drawback if the LCD size is large enough. LED backlights come in a variety of colors: green, red, blue, orange etc, and now white is becoming cost effective and very popular. LED backlights offer a longer operating life and are brighter than ELPs. Being solid state device, they are configured to operate with typically a +5V DC power, so they do not require an inverter. The LED backlight has two basic configurations: Array and Edge lit. In both types the LEDs are the light source that are focused into a diffuser that distributes the light evenly behind the viewing area. In Array lit configuration there are many LEDs mounted uniformly behind the display, it offers more uniform and brighter lighting and consumes more power. In Edge lit configuration, the LEDs are mounted to side (typically the top) as the light source which are focused into the diffuser, it offers a thinner package and consumes less power.

The highly integrated customization capability of LED backlight also enables the products to fit well to specific customer design needs, making the products unique to the customers’ applications.
