Like it is widely said that technology is dynamic, few months ago, the hype about super clear quality of the high definition television and 3D display took center stage and it seemed like that was the peak of graphical technology but obviously 3D-TV fad seems to be fading with the dawn of the cinema-style 4K, the cutting-edge technology whose screen resolution is four times greater than the so-called full HD display.
4K or Ultra-definition (UHDTV) as it also known has 3840 × 2160 resolution which gives about 8.3 megapixels. UHDTV builds digital images by approximately utilizing about 4,000 pixels horizontally and 2,000 pixels vertically resolution. Thus, it results in horizontal resolution in contrast to standard digital TV resolutions, which are stated in vertical lines. 4K displays a resolution that roughly doubles both the horizontal and vertical resolution of a normal 1080p television.
The 8K resolution represents 7680 x 4320 pixels (4320p) giving an equivalent of 33.2 Megapixels frames which is effectively 16 times more detailed than current 1080p (Full HD) resolution TVs. 4K TV is sometimes seen as the lower end of UHDTV or even Super Hi-Vision. The imagery details of the 4K display are so stunning, and viewers can comfortably sit close to the screen and even from just a few inches away and still find it hard to fiddle out a single pixel box on the display. Ultra High Definition TV (UHDTV) and 8K resolution with its 33 megapixel frames require up to 3.5 terabytes of storage for a mere 18 minutes of material and digitally produce ultra-realistic digital video format so real that some people could experience slight nausea while watching action movies on these platform.
The (organic light-emitting diode) screen technology offered an ultrathin display platform for both telegraphic devices and mobile computing devices with a much crispier, brighter image than a typical HDTV. The likes of Samsung Incorporated (with her Galaxy S series and Note series), has accepted the OLED technology as standard for the displays on their smartphones. Unlike conventional television, OLED has no backlight. The pixels themselves light up, allowing for deeper blacks and sharper contrasts.
Samsung has also made TVs smarter with their smart apps embedded in the device which thus providing alternative function for the by television platforms. Remote controls have been relegated as gesture control (motion controls, courtesy of a tiny camera that catches movement) which becomes the order of the day. Samsung also added new trick to the 3D TV platform, making it possible for two people to watch two different shows at the same time on same display. How possible? The images for one show alternate with the images for the other at an extremely high speed. Each person wears 3D glasses that have tiny shutters inside, the shutters flicker in time with images from show of each person’s program.
The increasing availability of 4K can deliver greatly improved video display image with smoother edge and depth combined with faster screen refresh rates.
