UHD Smart Tv is a term which is used interchangeably with 4K but there is a slight difference between the two in their technicalities. UHD or “Ultra High Definition” is a term which has been derived from the 4K standard of digital cinema. The local multiplex, however, shows movies in the native 4K resolution of 4096 X 2160 pixels while the 43 inch tv and above have a UHD format with a resolution of 3840 X 2160 which is slightly lower than the 4K multiplex resolution. This difference is hardly noticeable to the standard viewer and hence for all practical purposes, UHD Smart Tv and the 4K Smart Tv is believed to be one and the same.
The extra pixels that are added onto the UHD Smart Tv or 4K Tv give it a picture quality which is rarely experienced anywhere. The output images are a joy to watch since they are
- Sharply defined,
- Precisely detailed,
- The colours are vibrant,
- The picture quality clear with an amazing mix of colour contrast and brightness.
This picture quality thus manages to capture the eye of the viewer because it makes the content being displayed so much more interesting and intriguing. But this output is generally meant for Smart TVs of larger sizes so that they can be watched from even a short distance with the same effect. This is because for the UHD or 4K Tv:
- The closer the viewer sits,
- The better the visual field is filled up and
- Thus greater is the immersion.
Thus irrespective of the viewing distance there is no impact on the visual output which remains razor sharp throughout. This makes for some ground-breaking technological advance which also gets translated into the price of the same thereby making these Smart TVs priced much more than the other FHD Smart TVs or the HD Smart TVs.
Today viewing technology has proceeded from the light emitting diodes used for backlighting the display to something known as OLED. The basic difference between the acronyms of LED and OLED Smart TVs stems literally from the presence of the alphabet “O” in the acronyms. It stands for “Organic”, the word responsible or the huge difference in the OLED and the led tv price. Today, however, in spite of the higher price, OLED technology is being incorporated in 4K or UHD Smart TVs to make for a technology which results in ultra-thin and light Smart TVs displaying an incredible, never seen before contrast.
Pitching the two technologies together would give a clear picture as to why the prices of the OLED UHD Smart TVs are so much higher than the other LED TVs. Some of the factors in which the OLED technology scores are:
- Black level which is defined as the ability of the Smart Tv display to ensure that the blacks produced are deep and dark,
- Better response time and comparatively much lesser lag,
- All round viewing without any change in the picture quality,
- Lesser consumption of electricity etc.
The price of the OLED Smart 4K Tv, however, makes it beyond the reach of the common man. Hence these TVs are only favoured by the rich and the famous for the cinema like output it gives.
