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.

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.

Edge 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.

Graphical 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.

Character 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).
