In Array lit configuration there are many LEDs mounted uniformly behind the display,it offers more uniform and brighter lighting & consumes more power.In Edge lit configuration,the LEDs are mounted to on side(typically the top)focused edge on into the diffuser,it offers a thinner package and consumes less power.

LCD Backlights
The emergence of LEDsbright 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.
Graphical LCD Modules
The surface of the electrodes that are in contact with the LCD are treated so as to align the liquid crystal molecules in a particular direction.This treatment typically consists of a thin polymer layer that is unidirectionally rubbed using,for example, a cloth.The direction of the liquid crystal alignment is then defined by the direction of rubbing.Electrodes are made of a transparent conductor called Indium Tin Oxide (ITO).
Alphanumeric LCD Modules
LCD is an electro-optical amplitude modulator realized as a thin, flat display device made up of any number of color or monochrome pixels arrayed in front of a light source or reflector. It is often utilized in battery-powered electronic devices because it uses very small amounts of electric power.
LCD Modules
LCD uses liquid crystal fluid as the active medium to create images. The LCD module is made up by numbers of color or monochrome pixels. We Categories it in following types:

Inverters
An inverter is an electrical or electro-mechanical device that converts direct current(DC)to alternating current(AC);the resulting AC can be at any required voltage & frequency with the use of appropriate transformers,switching, & control circuits.static inverters have no moving parts & are used in a wide range of applications,from small switching power supplies in computers,to large electric utility high-voltage direct current applications that transport bulk power.
Energy Meter panels
Used with an overhead projector for a light source, an LCD panel can make an effective computer projection device, however LCD projectors have become a more economical choice."LCD panel" also refers to the smaller panels used internally in today's LCD video projectors.
LCD Panels
LCD is an acronym for Liquid Crystal Display.An LCD panel is a translucent glass panel that shows a computer or video image using a matrix of tiny liquid crystal displays, each creating one pixel ("picture element,"or dot) that makes up the image.
Energy Meter Modules
An electric meter or energy meter is a device that measures the amount of electrical energy supplied to or produced by a residence, business or machine.The most common type is more properly known as a kilowatt hour meter or a joule meter. When used in electricity retailing, the utilities record the values measured by these meters to generate an invoice for the electricity. They may also record other variables including the time when the electricity was used.
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.
LED 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.

LED Backlights
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.
Energy Meter 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.
Color LCD Modules
The surface of the electrodes that are in contact with the LCD are treated so as to align the liquid crystal molecules in a particular direction.This treatment typically consists of a thin polymer layer that is unidirectionally rubbed using,for example, a cloth.The direction of the liquid crystal alignment is then defined by the direction of rubbing.Electrodes are made of a transparent conductor called Indium Tin Oxide (ITO).
