Last month, LG Display unveiled the thinnest bezel public display LCD panel yet. Its 55” FHD (1920 × 1080 pixels), 800 nit, super-narrow bezel (SNB) display has only a 5.3 mm gap (bezel distance) when panels are arranged adjacent to each other, like a video wall. Panel makers continue to focus on commercial installations, aiming to get direct-view LCD technology into applications previously dominated by rear-projection displays, such as command and control centers or showcase retail locations. For instance, Samsung produced a 55”FHD, 700 nit, SNB panel with a measured gap of 5.7 mm.
Competition to have the thinnest bezel for commercial displays is not new. Samsung was one of the first in the SNB space with a 46” HD 700 nit 7.3 mm gap product. This product has had the most traction in the market to date. Last year, Sharp entered the SNB panel market with a 60” HD, 700 nit, LED-backlit panel with a 7.1 mm bezel gap.
Historically, there has been a trade-off between resolution and bezel size, with panel makers only making HD (as opposed to FHD) panels with small borders. For many commercial installations, where the displays are viewed at a distance, FHD is needed. However, the promotion of FHD in the consumer space and the general need to show advancements in technology have driven panel makers to attain FHD resolutions in SNB designs.
LGD’s announcement advances this trend and could open this market segment up further, enabling brands and installers to multi-source. The goal of LCD panel makers is to push down the price of multi-LCD panel installations in hopes of replacing rear projection (typically DLP) and/or plasma video walls. A DLP rear-projection solution typically has a 1 mm “mullion” (the term often used in video walls for the seam or gap between displays), and plasma panels typically have a 4.0 mm gap. Orion PDP (now just called Orion) has narrowed this gap to just 2.2 mm for its PDP video walls.
If the competition over gap size continues among LCD panel makers, as well as between LCD, DLP, and plasma makers, a zero seam gap multi-display will be the next progression. Some may argue that the winner will be whoever produces the technology for a zero-bezel display. Such a solution would not only benefit the developer, but it would also help to open new markets for all.
