“LED” stands for Light-Emitting Diodes. LEDs have undergone a significant evolutionary path from their original status of modest indicator lamps used in various household and industrial appliances, to the current status of light sources used to build quality images in the latest generation of monitors - LED displays. Overall, it is universally recognized as the best touch screen display technology. Electronic engineers appreciate LEDs for their high brightness and amazingly high efficiency. At the same time, LEDs have low power consumption which makes them the most environment-friendly light source. Users are also attracted by the high definition of the image provided by LED monitors, but for the average consumer, the revolutionarily thin, space saving features are what separate LED technology from the rest. In this article, we will talk about how the technology is applied, as well as how it may be used in the future.
LED Technology
Why is this technology so promising? It is worth taking the time to look at the technology itself. Advantages of LED lighting systems:
• The direction of the light flux - the ability to create a point-directed light. Most light sources produce light in all directions, so a large amount of radiance is wasted.
• Small size - even the largest LED luminaires, providing thousands of lumens of brightness, remain more compact than traditional analogs.
• Strength - the absence of glass and fragile parts. LEDs do not suffer from vibrations, which is extremely crucial in the production of industrial monitors.
• Resistance to low temperatures - allows for safe use in refrigerated display cases such as in supermarkets, refrigerators and outdoor lighting. It also allows for the manufacture of LED monitors for operation in extreme weather conditions. In this case, Xenarc Technologies succeeded in producing such monitors, which can operate in a wide range of temperatures.
• Instant on - does not require time to generate a full level of light output.
• Resistance to wear - service life does not depend on the on / off frequency, voltage drops.
• Controllability - 100% compatibility with electronic control systems that control the intensity and color of light flux.
• The absence of infrared and ultraviolet spectrum in white LEDs.
• The lack of harmful substances such as mercury – its high concentration in fluorescent lamps creates a real threat to human health and the environment.
Common applications for LEDs
• All kinds of light advertising
• Various light sources
• Home design
• Furniture design
• Architectural and landscape lighting
• Monochrome displays with a scrolling line
• Information boards
• Alphanumeric displays - from full-color displays at sports stadiums and shopping centers to single-color information boards
• In vehicles, to provide both external signaling functions, such as stop lamps and turn indicators, and in the interior of cars to illuminate the instrument panel
• Road signs and traffic lights
• As a backlight system in monitors, TVs, and projectors
The future of display technology, undoubtedly, is LEDs
However, the improvement of the quality of info displayed by various electronic devices is a constant process; manufacturers are eager to make potential customers happy with a high quality image. Looking down the road, the next generation of displays are based on MicroLED technology, also known as QLED and OLED, which are the next evolution of LED technology.
