Q:- What is L.E.D. ???

A light-emitting diode (LED) is a semiconductor device that emits visible light when an electric current passes through it. The light is not particularly bright, but in most LEDs it is monochromatic, occurring at a single wavelength. The output from an LED can range from red (at a wavelength of approximately 700 nanometers) to blue-violet (about 400 nanometers). Some LEDs emit infrared (IR) energy (830 nanometers or longer); such a device is known as an infrared-emitting diode (IRED).

An LED or IRED consists of two elements of processed material called P-type semiconductors and N-type semiconductors. These two elements are placed in direct contact, forming a region called the P-N junction. In this respect, the LED or IRED resembles most other diode types, but there are important differences. The LED or IRED has a transparent package, allowing visible or IR energy to pass through. Also, the LED or IRED has a large PN-junction area whose shape is tailored to the application.

Benefits of LEDs and IREDs, compared with incandescent and fluorescent illuminating devices, include:

• Low power requirement: Most types can be operated with battery power supplies.
• High efficiency: Most of the power supplied to an LED or IRED is converted into radiation in the desired form, with minimal heat production.
• Long life: When properly installed, an LED or IRED can function for decades.

Typical applications include:

• Indicator lights: These can be two-state (i.e., on/off), bar-graph, or alphabetic-numeric readouts.
• LCD panel back-lighting: Specialized white LED's are used in flat-panel computer displays.
• Fiber optic data transmission: Ease of modulation allows wide communications bandwidth with minimal noise, resulting in high speed and accuracy.
• Remote control: Most home-entertainment "remotes" use IREDs to transmit data to the main unit.
• Optoisolator: Stages in an electronic system can be connected together without unwanted interaction.

LED ADVERTISING SCREENS

High Resolution LED Lamp and SMD Technology

When we started producing the first full colour LED modules . we saw a massive future potential for the technology within the advertising industry. Unfortunately back then full colour LED technology was extremely expensive and it was very difficult for media / marketing companies to see the benefits and recoup advertising revenue from the initial capital investment. This is the main reason why this technology became a popular rental solution and more suited to stadium applications and outdoor events.

Today things are very different, the technology has advanced and component costs have reduced. The timing could not be better to launch a NEW range of modules specifically focused on advertising applications. This means smaller screen sizes with a higher resolution to meet customer’s advertising budgets. Our key focus have been to develop a number of high resolution modules using our high brightness SMD (3-in-1) technology and dot matrix boards. The result is a number of cost effective screens solutions for the signage, display and advertising industries.

Indoor / Window / Semi Outdoor Advertising Screens

Our new range of high resolution full color LED modules offers a costs effective solution to smaller scale digital billboard advertising, poster displays, banners and our LED light-box. Sai Display Board is focused on developing a number of screen solutions which differ from conventional LED displays by adding a whole new dimension to the use of the technology, creating movement and impact without the large price tag.

Digital LED Billboards (landscape or portrait)

The focus here is to offer smaller scale LED advertising boards using a high resolution module for closer viewing, making them ideal for all low level advertising applications within shopping centres, airports, bus/rail stations, visitor attractions, exhibition halls and outdoor pedestrian walkways. They also have a great impact for window advertising applications. This type of screen can be any size or shape (aspect) and also integrate well with larger static billboard poster displays.

Other LED advertising solutions include:

· LED 6 Sheet Poster System
· LED Light-box Sign
· LED Banner Screens
· LED TV

SMD (3-in-1) Technology
 Sai Display Board has made many advances in its range of SMD (3-in-1) screen solutions over the last two years with the development of a new range of chips from Nichia and CREE. Utilising special techniques we have been able to increase brightness and contrast levels on the boards to create a costs effective range of full colour indoor / semi outdoor displays.

Indoor / Window / Semi-Outdoor Modular Screen Systems
Pixel Pitch  -  6mm, 8mm, 10mm, 12mm

New for 2008 – 4mm pixel pitch.

Dot Matrix Technology
Utilising new manufacturing techniques our engineers have recently been able to develop a range of high brightness full colour dot matrix modules to create cost effective displays for the signage / advertising industry. These high resolution display modules are available in 6mm, 7.62mm and 10mm pixel pitch, with a brightness level of 2700 nits making them suitable for both indoor / window / semi outdoor applications. The board design means the display has a more even surface offering greater uniformity and colour blending across the surface.
