Selected Features

QNED - QLED + Nanocell on LG 55QNED829QB

LG 55QNED829QBuses QNED technology on its LCD display which is combination of QLED and Nano Cell technologies. Quantum dot LED (QLED) TV has a LED backlight LCD display with additional semiconductor nanocrystal layer that produces different colors of light depending on the size of the particle. Quantum dots are able to emit precise colored light because particle sizes adjust at quantum-level velocities, resulting in accurate and efficient light emissions. This results in more accurate color reproduction and can even achieve a full coverage of BT.2020 color gamut. Besides color Quantum dots also offer high brightness which results in high contrast ratio. This is especially important when displaying HDR content. In Addition, Nano Cell layer has particles which absorb unwanted light wavelengths and enhance the purity of the red and green colors displayed on the screen. They create subtler, more accurate colors that stay true, even at wide viewing angles. So, even if the whole family is gathered around the TV, everyone has the best seat in the house, whether they’re front and center, or across the room and off to the side.

VA Panel on Sony KD-55X720E

Sony KD-55X720E has a vertical alignment (VA) panel. Such panels are most commonly used in LCD TVs as they provide deeper blacks compared to the IPS panels. However, they are still limited with the viewing angles compared to the IPS panels or OLED displays.

HDR10

LG 55QNED829QB and Sony KD-55X720E support HDR10 which was announced on August 27, 2015, by the Consumer Technology Association and uses the wide-gamut Rec. 2020 color space. It is not backward compatible with SDR. It sends static metadata via video stream to the TV which calibrates its screen brightness and color according to that. HDR10 is technically limited to a maximum of 10,000 nits of brightness and uses 10-bit color which corresponds to 1024 shades of the primary RGB colors.
