Selected Features
Nano Cell Technology
LG Nano Cell technology uses particles to absorb unwanted light wavelengths and enhance the purity of the red and green colors displayed on the screen. In addition, 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.
IPS Panel
LG 55SK9000PUA has an in-plane switching (IPS) panel which is not commonly used in LCD TVs as they suffer from light leakage which lead to the lower contrast and poor HDR experience. However, this type of panel can provide better viewing angle and color accuracy compared to the VA panel.
Full-Array Local Dimming
The TV has Full-Array Local Dimming technology with multiple zones throughout the display. Individual zones of LEDs can light up independently which enhances black levels, shadow details and decreases level of light bleed in dark parts of the image. This gives higher contrast with increased picture quality which is very important for HDR reproduction. Higher number of zones gives better control over local dimming and less blooming around the bright objects and subtitles. This particular model has 48 zones.
HDR10
LG 55SK9000PUA supports 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.
Dolby Vision
This TV also supports Dolby Vision which is an update to HDR10 by adding dynamic metadata that can be used to more accurately adjust brightness levels up to 10,000 nits maximum brightness on a scene-by-scene or frame-by-frame basis and support up to 12-bit color depth (4096 shades of RGB) and 8K resolution.
