LED TV Systems
LED (Light Emitting Diode) technology has actually been around since the early part of the 19th Century, gaining a certain notoriety in the 70s with the arrival of bright red lit LED watches.
It is the recent integration of LEDs into the familiar LCD flat panel TV however, that marks an exciting new development of a technology which offers the potential for a superior viewing experience.
Not only does LED technology offer the prospect of deeper blacks, but the potential for sharper images, more vibrant colours, faster response time and greater energy efficiency.
In LED Technology, numerous small LEDs are used to create images, while in conventional LCD displays fluorescent lamp backlight is used. LED technology is also used in laptop screens, and is proven to be energy efficient and competent in rendering good video performance. The advantages of LED Technology includes low power requirement, better picture clarity and more precise control over tonal range and contrast of the images. In standard LCD television, a single tube is used to produce backlight system (CCFL). Hence controlling individual pixels for producing higher picture contrast is not possible in the case of fluorescent lamp backlight system. In the case of LED backlight system, numerous small LED bulbs are used to create image. These LEDs can be switched on or off according to the intensity of colour needed in that particular image, which in turn helps to augment the picture clarity, contrast and colour reproduction of the television dramatically.
The Light Emitting Diode technology is much greener compared to the other display technologies. It needs absolutely zero mercury for manufacturing a LED television. Mercury is quite hazardous to the environment and is capable of causing ecological jeopardise when used in bulk. Lighting consistency is yet another advantage of this television.
LED Televisions are shock resistant and sturdy, yet wafer thin that adds beauty to the living space as a much adorable piece of art. The life span of the display is expected to be higher in the case of Light Emitting Diode displays compared to the displays of other prevailing technologies.
The energy demand of these screens are quite low, and one can save 40% of power compared to a normal LCD television. Innovations are made in the LED backlight system too. Initially the LED screens made use of the edge lit technique in which the LED bulbs are placed near the frame to render good images. However the new direct lit technique has emerged with the help of white LEDs to rectify the side-effects of edge lit LED displays.
1. Picture Quality Quite simply, the picture quality has been improved over standard LCD and Plasma, because the range of colours have increased. The utilization of Light Emitting Diodes as a light source instead of traditional lamps provides a higher contrast ratio because the LED produces blacker blacks and whiter whites, this is the key to achieving quality images on screen.
2. Environment LED Technology consumes less power than current backlight TV technology, making a saving on your energy bills.
3. Slimmer Models. Since no provision for a conventional light source is required, LED TVs can be made ultra thin, this makes for a thin, sleek, more attractive model.
