Seoul, Korea, Jan.10, 2017/Korea IT Times – LG Display announced today that it will introduce the world’s first 5.7-inch QHD+ LCD panel with a 18:9 aspect ratio,responding to growing consumer demand for bigger, better screens on smartphones.

The company will supply the panel to LG Electronics for its next flagship smartphone this year.

The most notable feature of the new mobile display is its “18:9 aspect ratio.” Displays, which take up the
largest area of smartphones, have evolved from an aspect ratio of 4:3, to 3:2, 5:3 and 16:9; lately, a 17:9
ratio display has been introduced. Due to increasing consumer demands for bigger screens, LG Display
developed the 18:9 aspect ratio display to provide more immersive viewing experiences.

The new 18:9 aspect ratio represents LG Display’s direction on how displays should evolve, while
meeting the rising trend for watching videos on smartphones. The 18:9 aspect ratio is also optimized for
multi-tasking, using dual-screen functions.

QHD refers to a resolution of 1,440x2,560 - four times the number of pixels on a standard HD display
(720x1,280), which employs 538 Pixel per Inch (PPI), based on a 5.5-inch panel. LG Display’s new 5.7-
inch panel called QHD+, has a resolution of 1,440x2,880 with 564 PPI, which is higher than conventional
QHD LCDs.

The new product not only provides excellent touch responses, thanks to the company’s exclusive inTOUCH
technology, but also helps achieve a thinner and lighter smartphone due to the absence of Touch
Cover Glass. The module (excluding the cover glass) is super slim, being less than 1mm thick, and has
reduced bezel width by 0.2mm (20 percent) on top, and by 0.54mm (10 percent) on the left and right
sides, compared to conventional QHD LCDs.

LG Display has also improved the outdoor visibility of the panel by increasing transmittance by 10 percent,
while reducing power consumption by 30 percent. Outdoor visibility and low-power consumption are
major criteria for consumer choices for smartphones.

“We expect to maximize user experience and customer value through the super high-quality display with
its new 18:9 aspect ratio, which sets it apart from conventional displays for smartphones,” said Dr.
Byeong-koo Kim, Senior Vice President and Head of Mobile Development Group 1 at LG Display. “LG
Display will continue to set new standards in premium mobile displays, based on its differentiated
technology.”
