Light Emitting Diode

Light Emitting Diode, or 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 that most of the other methods, and this is a major drawback if the LCD size is large enough.

Edge Backlights

The emergence of LEDs bright enough to backlight large LCD displays promises to reshape power requirements in LCD. Recent announcements and technology demonstrations provide further evidence that increases in LED light output are making these solid-state lamps viable replacements for the cold cathode fluorescent lamps (CCFLs) currently used in large LCD displays. The adoption of LED backlights in these applications promises to reduce the power consumed by backlighting(in the long run, if not always in the near-term LED backlight solutions.)At the same time,LED backlights should alter the backlight’s power supply requirements.

Edge Backlight

A backlight is a form of illumination used in liquid crystal displays(LCDs).Backlights illuminate the LCD from the side or back of the display panel,unlike frontlights,which are placed in front of the LCD.Backlights are used in small displays to increase readability in low light conditions, and in computer displays and LCD televisions to produce light in a manner similar to a CRT display.

LED Backlights

LED Backlight is thin,light weight design.This product has an even surface with wide viewing angle which gives high luminosity.The LED Backlight has low power consumption,low voltage & operated on a low current.This is easy to install.This Backlight can be made in different shapes & sizes.LED Backlight can be made in different colours such as Red,White,Yellow Green,Amber,Yellow,Blue,Green & Orange.

Character LCD Modules

More microcontroller devices are using'smart LCD'displays to output visual information.The following discussion covers the connection of a deepakshi LCD display to a PIC microcontroller.LCD displays designed around HD44780 module,are inexpensive,easy to use & it is even possible to produce a readout using the 8x80 pixels of the display.Deepakshi LCD displays have a standard ASCII set of characters plus Japanese,Greek & mathematical symbols.
