Back lights are used in small displays to increase readability in low light conditions.LED (Light Emitting diode) back light is the most popular back lighting for small and medium LCD. The advantage of LED Backlighting is its low cost, long life, immunity to vibration, low operational voltage and precise control over its intensity.LED Backlights comes in a variety of colors like, Red, Green, Yellow, White, and Blue. LED Backlights have longer operating life more than 50,000 hours and are brighter than ELPS (Electro-luminensce panel).The LED backlight has two basic configurations- Array and Edge lit Backlight. In both types the LEDs are the light source which is focused into diffuser that distributed the light evenly behind the viewing Area.In array lit configuration Many LEDs are mounted uniformly behind the LCD display,In Edge lit configuration the LEDs are mounted onto one side of LGP and with a focused edge into the diffuser. It is made in thinner package and consumes less power.+ Read More
