LAS VEGAS—Most product and series announcements at CES are for one type of device. A company will announce an HDTV, a speaker, a washing machine, or a tablet. LG is eschewing that tactic by revealing LG Signature, the company's cross-category premium brand that combines home electronics and appliances.

LG Signature products—the first of which include an HDTV, fridge, washing machine, and air purifier—are stark and stylish. They're designed by Torsten Valeur, master designer of the line and president of David Lewis Designers.

First up is the LG Signature OLED G6, the company's newest and highest-end HDTV. It takes LG's philosophy of minimizing HDTV bezels to an extreme by eliminating them entirely. The organic light-emitting diode (OLED) panel is attached to a single glass sheet, measuring just 2.57mm thick with no physical frame. The base is an integrated speaker system that can fold behind the screen for wall mounting.

Because it's an OLED panel, it lacks a separate backlighting system and, if it performs remotely similar to previous LG OLED HDTVs we've reviewed, it's capable of displaying perfect black levels. The G6 supports high dynamic range (HDR) content with Dolby Vision, and LG claims it can cover 99 percent of the DCI color space. It is, of course, an ultra high-definition (UHD or 4K) television, and the president of the UHD Alliance, Hanno Basse, appeared at LG's press conference to discuss the G6's UltraHD Premium certification.

The new LG Signature washing machine is a stark white-and-black box that looks like a console from 2001: A Space Odyssey. It's an all-in-one washer-dryer unit that features a heat pump for drying, and incorporates a Centum drive suspension system that LG says reduces noise. The controls are integrated into a touch-sensitive disc on the front-loading door. Oddly, the model displayed at LG's press conference doesn't seem intended for the U.S. market; a separate stainless steel version will be released for North America.

The LG Signature air purifier users a semi-permanent filter system that can be washed repeatedly for up to 10 years, and can remove particles as small as one micrometer.

Finally, the new LG Signature fridge is a stainless steel side-by-side-door fridge with LG's door-in-door for easy access to foot items. The door features smart glass that automatically becomes clear when you knock on it, and darkens when you walk away. A foot sensor on the fridge also automatically opens the door when you put your foot in front of it, and the interior is clad in stainless steel, like the exterior.

LG has not yet yet announced pricing or availability for the LG Signature line in the U.S. An LG Signature dishwasher and oven are coming later this year.
