What is HD and FHD?

HD = High Definition
FHD = Full High Definition

Full HD delivers 1080p resolutionHD delivers 720p resolutionResolution refers to the number of pixels that compose the picture on the TV.

What is UHD?

UHD PICTUREUHD SIGNALHDMI 2.0HEVC 265 FORMATUHD PANELUltra-High Definition TV (4K UHD) has a resolution of 3.840 x 2.160 pixels= a total of 8,3 megapixels for 16:9 ratio

UHD delivers a 4x higher picture quality and higher resolution image than FHD (1080p).

What is QLED?

The Quantum Dots are tiny nanoparticles that intensely improve the color and brightness of the LCD panel they are embedded in.QLED filters the light to recreate the colourson the display by Quantum Dot Enhancement Film (QDEF). It simulates OLED features by improving the contrast ratio and local dimming compared to Display LED. Improved brightness and color reproduction

− QLED produces more light (brighter) than OLED pixels can emit by not overpowering the pixels with too much light.

− Wider color gamut = More precise colors

What is OLED?

OLED (Organic Light Emitting Dots) display is self-emissive, which means each pixel is capable of generating its own light (no Backlight).

− Highest contrast ratio, deepest blacks / whites and best black uniformity Highest Dimming Zones−Highest HDR performance−Thinnest (there is no backlight)
− No heat issue (there is no backlight) and generally cooler in temperature than LCD−Exceptional viewing angles
− No blooming and no motion blur−They support the latest technology incl. HDR, Dolby Vision and 4K UHD resolution

What is Mini-LED?

Mini-LED is another type of backlighting technology used for LCD TV.
Full Array LED = Mini-LED Backlight

−Better contrast ratio than LCD TV
−Higher luminance (brighter) compared to OLED
−Wider color gamut using Quantum Dot films or RGB chips
−Better HDR performance compared to LCD TV
−Reduced thickness compared to traditional LCD, but thicker than OLED
−Longer life span than OLED

UHD Ultra high definition so better picture quality.
HDR High dynamic range so again better picture quality And smart TVs have pre loaded apps such as Netflix and Amazon prime. Regular TV's usually do not have HDR OR UHD and do not look as good as smart 4k TV's.

LED UHD is an abbreviation for Ultra High Definition, which means that the number of pixels in a screen is four-time bigger than a usual 1080p Full HD TV.
LED is an abbreviation for Light Emitting Diode, which means that the TVs use LEDs instead of CCFL lighting to create light in their screens.
