The Liquid Crystal Display (LCD) television has become a hot favourite of consumers, thanks to the superior technology adopted in its making. Ever since it was introduced in the market, periodical up gradations were effected in response to the comments and complaints from the public. Many new techniques are being adopted to improve the performance of the product. Some of such techniques are unique to LCD television. LED backlighting is one among them.
The new lighting system has been acknowledged as having enormous potential in the television technology. There are experts who visualize that LED backlighting will replace all other techniques of lighting in the near future. LED (Light Emitting Diode) is now widely used in the LCD television of small and medium sizes. This lighting system facilitates saturated colours and superior colour reproduction. Among all other methods of backlighting LED is the most popular system due to many advantages. Apart from colour saturation and supreme quality reproduction, low cost and durability are other major advantages. It is available in many colours. Yellow green and white are the colours generally available.
With a life span of 50,000 hours or more, it is the most durable lighting system in the television industry. Frequent replacement of bulbs is not at all necessary like other lighting systems. Another advantage is its ability to enhance black levels. The use of more than three colours in the backlight enables the system to exceed NTSC colour range. Further this backlighting system can run on low voltage. Again, the LED backlighting system eliminates delay in the commencement of display and do not require initial ‘warm up’ time. This new backlighting enhances the refresh rates contributing to superior picture clarity.
All leading manufacturers of LCD television are contemplating on incorporating LED backlighting in view of the advantages mentioned above. Samsung is one example to point out. The popularity of this brand of LCD television is an indication of consumer acceptance of the technology involved. In the highly competitive market it is essential to convince the consumers about the qualitative advantages and cost effectiveness of the product. The Light Emitting Diode with its remarkable longevity will effect substantial savings for the consumers, since frequent replacement of bulbs is not necessary as mentioned earlier. This system is yet another feather in the cap of LCD television.
