The display remains one of the critical differentiators in smartphones and the major suppliers are always racing to be first with a technology to make handsets slimmer, brighter or, soon, more flexible. LG Display’s latest breakthrough is to unveil what it claims to be the world’s slimmest Full HD LCD panel for smartphones.
The panel is 5.2-inches long and just 2.2 millimeters thick with a 2.3 millimeter bezel, and deploys the Korean firm’s OGS (One-Glass-Solution) technology commercially for the first time. Another key technique is to use dual flexible printed circuits between the panel and touch film, rather than single circuits, which reduces the number of lines on the panel by more than 30%, according to LG. It also uses a direct bonding system, optical clear resin, between the panel and film, for enhanced brightness.
The product supports Full HD (1,080×1920 pixels with RGB sub-pixels) and brightness of 535nits, and also claims clear visibility even in strong outdoor light.
The latest development follows hard on the heels of LG’s recent announcement that it was starting mass production of flexible and unbreakable smartphone display panels, using superthin, light LCD technology to support bendable screens. Samsung, Nokia and Apple are all interested in superslim and flexible displays, and Nokia has recently discussed its use of graphene for mobile devices, claiming this is the strongest, lightest and thinnest material on earth.
Byeong-Koo Kim, VP of LG Display’s IT and mobile development group, said in a statement: “LG Display will continue its commitment to developing products that maximize consumer value as well as opening new doors for the mobile and tablet PC industry.”
