At the ongoing CES 2019 in Las Vegas, LG Display has showcased a bunch of new OLED displays including the world’s first rollable TV.

However, the most interesting of the lot is a gigantic 88-inch OLED screen that offers a surreal 8K resolution and can double up as a speaker.

The newest 88-inch model comes as an improved version of Crystal Sound OLED screens that were showcased at CES 2017.

The ‘Crystal Sound’ screen technology allows LG Display to integrate a dedicated sound system into the display and hence remove the need for speakers.

This 88-inch model is claimed to offer more immersive sound with a 3.2.2-channel Dolby Atmos audio.

Given OLED displays are self-emissive and do not require backlighting, with ‘Crystal Sound’ screen technology, LG Display is able to embed a sound system into the screen itself.

This characteristic of OLED screens allows them to be used as membranes with several exciters packed across the panel.

When active, these exciters generate audio through vibrations of the OLED display.

Besides removing the need for a separate speaker or sound bar, the Crystal Sound screen technology offers a more immersive viewing experience.

This is because the sound waves beam out from behind the display than side-mounted or bottom-firing speakers.

Interestingly, LG Display is also bringing this technology into both laptops and PC monitors.
