Differences between HD TV


A 4K display reveals so much more detail. The higher pixel density of a 4K panel also enable you get much closer without the grid-like structure of the image itself becoming visible. More and more movies and streaming services are start to stream and video in 4K. If you want to be ahead of the curve, now is the time to buy a 4k HDTV.


Ultra-high-definition television (UHDTV)

UHD experience gets you closer to the action than ever before. Stunningly sharp images mean amazing clarity.It converts lower resolution content – such as live TV – to a level of detail that’s four times better than Full HD. UHDTV also allows for frame rates up to 120 frames per second.


Liquid-Crystal Display (LCD)

LCDs are available to display arbitrary images (as in a general-purpose computer display) or fixed images with low information content. Its low electrical power consumption is great for saving energy if your worried about your power bill. LCDs used in television sets, monitors and smartphones have high-resolution matrix arrays of pixels to display arbitrary images using backlighting with a dark background when no image is displayed.


Light-Emitting Diode (LED)

Many brands use LED backlighting technology, which offer the advantages over CCFL LCDs of reduced energy consumption, better contrast and brightness, greater color range, more rapid response to changes in scene and more accurate image rendering and they last longer.


Organic Light-Emitting Diode

OLEDs are used to create digital displays in devices such as television screens, computer monitors, portable systems such as mobile phones, handheld game consoles and PDAs. An OLED display works without a backlight; thus, it can display deep black levels and can be thinner and lighter than a liquid crystal display (LCD). In low ambient light conditions (such as a dark room), an OLED screen can achieve a higher contrast ratio than an LCD, regardless of whether the LCD uses cold cathode fluorescent lamps or an LED backlight.



Plasma displays are bright, have a wide color gamut, and can be produced in fairly large sizes—up to 3.8 metres (150 in) diagonally. They had a very low-luminance “dark-room” black level compared with the lighter grey of the unilluminated parts of an LCD screen. The lifetime of the latest generation of plasma displays is estimated at 100,000 hours of actual display time, or 27 years at 10 hours per day.
