More than just enabling the transparent screen to better display blacks, however, the Partial Screen actually enables other use cases that make the display look more interesting. In fact, they might look even more lush and vibrant, thanks to the increased contrast. And since LEDs emit their own light, unlike LCDs, the “blinds” don’t prevent the display from showing other colors. This, in effect, creates an opaque background that will finally make blacks pop out and increase the display’s contrast. What happens is that when all the shutters rotate and face forward, they completely block any light from shining through the back of the enclosure. While the shutters look interesting themselves, they serve a greater purpose of turning the transparent display into a regular screen. These 25 shutters are individually motorized, and each can turn independently of one another, which makes it easy to have them move in succession or in specific patterns. In this concept, a 55-inch transparent display is framed inside a wooden box, with what looks like wooden slats behind it.
LG Display collaborated with designers to think of possible solutions, and the Partial Screen is one such concept with a literal twist. In particular, transparent OLEDs like the ones being pushed by LG have problems with black colors because of how ambient light can shine through the back.
It is admittedly a technological marvel that deserves some praise, but its novelty quickly wears off when one starts to show normal content. Transparent displays look almost magical because of how we’ve become accustomed to knowing there are electronics or even backlighting behind the screen.
