LED DISPLAY


A LED display is a flat panel display that uses an array of light-emitting diodes as pixels for a video display. Their brightness allows them to be used outdoors where they are visible in the sun for store signs and billboards. In recent years, they have also become commonly used in destination signs on public transport vehicles, as well as variable-message signs on highways. LED displays are capable of providing general illumination in addition to visual display, as when used for stage lighting or other decorative (as opposed to informational) purposes. LED displays can offer higher contrast ratios than a projector and are thus an alternative to traditional projection screens, and they can be used for large, uninterrupted (without a visible grid arising from the bezels of individual displays) video walls. microLED displays are LED displays with smaller LEDs, which poses significant development challenges.[1]

The first practical LED display was developed at Hewlett-Packard (HP) and introduced in 1968.[3] Its development was led by Howard C. Borden and Gerald P. Pighini at HP Associates and HP Labs, who had engaged in research and development (R&D) on practical LEDs between 1962 and 1968. In February 1969, they introduced the HP Model 5082-7000 Numeric Indicator.[4] It was the first LED device to use integrated circuit (integrated LED circuit) technology,[4] and the first intelligent LED display, making it a revolution in digital display technology, replacing the Nixie tube and becoming the basis for later LED displays.[5]


The entire idea of what could be done with LED was given an early shake up by Mark Fisher's design for U2's PopMart Tour of 1997. He realized that with long viewing distances, wide pixel spacing could be used to achieve very large images, especially if viewed at night. The system had to be suitable for touring so an open mesh arrangement that could be rolled up for transport was used. The whole display was 52m (170ft) wide and 17m (56ft) high. It had a total of 150,000 pixels. The company that supplied the LED pixels and their driving system, SACO Technologies of Montreal, had never engineered a video system before, previously building mimic panels for power station control rooms.


Today, large displays use high-brightness diodes to generate a wide spectrum of colors. It took three decades and organic light-emitting diodes for Sony to introduce an OLED TV, the Sony XEL-1 OLED screen which was marketed in 2009. Later, at CES 2012, Sony presented Crystal LED, a TV with a true LED-display, in which LEDs are used to produce actual images rather than acting as backlighting for other types of display, as in LED-backlit LCDs which are commonly marketed as LED TVs.


The 2011 UEFA Champions League Final match between Manchester United and Barcelona was broadcast live in 3D format in Gothenburg (Sweden), on an EKTA screen. It had a refresh rate of 100 Hz, a diagonal of 7.11 m (23 ft 3.92 in) and a display area of 6.1923.483 m, and was listed in the Guinness Book of Records as the largest LED 3D TV.[6][7]

LED Display (light-emitting diode display) is a screen display technology that uses a panel of LEDs as the light source. Currently, a large number of electronic devices, both small and large, use LED display as a screen and as an interaction medium between the user and the system. Modern electronic devices such as mobile phones, TVs, tablets, computer monitors, laptops screens, etc., use a LED display to display their output.


LED Display is one of the main screen displays that are being commercially used. The biggest advantage of the LED display is its efficient and low-energy consumption, which is especially needed for handhelds and chargeable devices such as mobile phones and tablets. An LED display consists of a number of LED panels that, in turn, consist of several LEDs. LEDs have numerous advantages over other light-emitting sources that can be used alternatively. Aside from being power efficient, LEDs produce more brilliance and greater light intensity. LED Display is different from the vacuum fluorescent display used in some consumer electronics such as car stereos, videocassette recorders, etc., and, hence, these two should not be confused with each other.


It was not until 1994 that Japanese scientist Shuji Nakamura was able to demonstrate an efficient blue LED. White and green LEDs soon followed, laying the foundation for the LED revolution we have seen in lighting and display technology.


To create a bright colour image, the principles of additive colour mixing are used, whereby new colours are created by mixing light in different colours. An LED display consists of red, green and blue LEDs mounted in a fixed pattern. These three colours combine to form a pixel. By adjusting the intensity of the diodes, billions of colours can be formed. When you look at the LED screen from a certain distance, the array of coloured pixels are seen as an image.


RGB is short for Red, Green and Blue. It is a colour scheme that exploits the fact that all visible colours can be mixed from these three basic colours. It is used in almost all types of displays, including LED displays.


In LED display technology, the SMD concept is used a little differently. An SMD display is an LED display where the red, green and blue diodes are potted in a small plastic encapsulation which is surface mounted on the printed circuit boards of the display. When the diodes are encapsulated in this way, they take up a lot less space, making it possible to produce displays with less spacing between the diodes and higher resolution.


LED is a highly energy-efficient technology, hence the widespread use of energy-saving LED bulbs today. The amount of power the diodes in an LED display use depends on the type of display, brightness and usage.


There are many different types of LEDs and displays. The power consumption of an indoor display, for example, will be different from an outdoor digital sign, which has to be seen in direct sunlight. The brightness of the display is also a major factor. The images must be clear, but the light from the display must not dazzle. An outdoor LED display needs to be far brighter in daylight than when darkness falls.


It is difficult to say anything specific about the life of an LED display as many factors come into play. However, with proper maintenance, a display can certainly last for more than ten years. As with all types of electronics, life expectancy is also affected by the daily use and the environment around the display. Light images and a high level of brightness are more wearing on the display than darker images and a low level of brightness. Factors such as humidity and salt content in the air can also come into play.


Over the course of the life of an LED display, the light output from the diodes will diminish. By how much depends on the type and generation of the diodes. Many LED displays never use their full light intensity, so reduction will rarely be a problem.


If an LED display has a pixel pitch of 1 cm, there may be 100 x 100 pixels per square metre of display. The resolution of a display is given as a pair of numbers that indicate the width and height in pixels. If you have a 6 x 8-metre screen with 1 cm in pixel pitch, it has a resolution of 600 x 800 pixels. 041b061a72
