The evolving LCD TV technology aims for better viewing experience
CRT TVs ruled at the top of large screen display technology since the year 2007, when their dominance ended. That year saw the worldwide sales of CRT being overtaken by the sales of LCD TV. Coming from the era of great technological feats achieved in the TV technology, the Liquid Crystal Display (LCD) technology has many advantages over the Cathode Ray Tube (CRT) technology.
The tube in the CRT TV has to maintain vacuum since the electrons could have got deflected due to the presence of the gas molecules. The passing of the current excites the electrons and the same need to be focused on to the display after accelerating their motion. This heated the tube and also restricted the use of display screen to up to 30 inches in width. The various quality parameters were inferior and audio-visuals did not give a great viewing experience as compared with the current display devices.
LCD technology removed these limitations and provided many new and exciting features. The CCFLs provide the back light (can also be replaced by LEDs) in a LCD TV. The white light is selectively filtered. Millions of shutters and the associated colour filters ensure that only the red, green and blue light is made to pass through them in a measurable quantity. It make use of the principles of polarization of light to display the light in the image colours on the screen. The small vacuum in LCD is contained in the CCFLs only.
The LCD displays are far lighter in weight since the heavy glasses used in CRT are dispensed with. This takes off a large chunk of weight load from the TV. Furthermore, the thickness of the screen display is less in case of LCD. Theoretically, LCD technology based TVs can be made in any size. The only limiting factor will be production yields. The more the yield the wider is the screen size. The image quality of the current LCD TV is better than the earlier versions. The innovation involving the ‘Overdrive' technology and the adding of memory to hold the contents of the display, has improved the response times significantly. Further improvement is likely by making use of ‘super-sampling'. The contrast ratio is another area where these TVs are evolving technologically. The ‘dynamic backlighting' is being made use of to improve the contrast ratios so that the black or near black scenes do appear black.
If someone were to assume that the LCD TVs are better in power consumption as compared to the CRT, than that is not the case. These consume almost same amount of power as the CRT ones, so you cannot think of effecting savings on your power bill by getting the LCD based TV installed.
LCD TV technology is still evolving and it cannot be said that the best of LCD has been achieved. There is a lot of scope for improvement in the image quality parameters where it rivals like plasma TVs and even the good old CRT TVs still score over better.
