LG Develops Smartphone Display with Super-Thin Bezel

LG has developed a 5.3-inch Full HD LCD panel for smartphones with the world’s narrowest bezel at 0.7mm. With this cutting-edge display, LG Display continues to lead the market in high-resolution large-size displays for mobile devices.

“With the growing trend for large screen smartphones, customer demand for displays with a narrow bezel is increasing, because it enables users to enjoy the maximum use of screen area without compromising excellent grip and design,” said Byeong-koo Kim, Vice President and Head of IT/Mobile Development Group at LG Display. “With this innovative product having many advantages, ranging from its narrow 0.7mm bezel and high resolution picture quality to its slim design and touch-embedded solutions, LG Display will continue to lead the growing market for large screen smartphones, meeting the expectations of customers and users by enhancing the quality of devices,” said Mr. Kim.

To realize the 0.7mm bezel width on the left and right sides of the panel, which is narrower than the 0.8mm thickness of a credit card, LG Display used its “Neo Edge” module processing technology and the world’s first “Advanced In-Cell Touch (AIT)” technology.

LG Display’s Neo Edge technology uses an adhesive instead of double-sided tape to attach and completely seal the total area and edges of the panel’s circuit board and backlight unit. Because there is no plastic guide panel to attach the panel and backlight, the Neo Edge technology helps achieve minimal bezel width, while blocking light leakage and being waterproof and dustproof.

The adhesive seal also prevents corrosion that sometimes occurs along the edge of the glass panel when double-sided tape is used, while dramatically improving the panel’s durability despite the narrow bezel because of increased elasticity as the adhesive hardens.

The company’s AIT technology, exclusively developed by LG Display, reduces the need for bezel space because the touch panel is embedded into the LCD module. The technology offers a slim design and excellent touch, while saving costs since a separate process for touch functions is not required.

LG Display will start mass production of the product in November and supply it first to customers in China, where demand for large screen smartphones is strong, while actively promoting it globally. (Press Release)
