LG Wants to Slim Down Smartphones, Starting With Screen
7/15/2013 by: Denis Jelec
Last Thursday LG Display Co Ltd. (NYSE:LPL) said that they have managed to develop the world’s thinnest FullHD LCD panel for smartphones (or rather phablets given its 5.2” size). This 2.2mm thin 1080p screen also has a very thin bezel (2.3mm) and is able to outperform every other FullHD LCD panel out there, according to the company.
In order to create a panel this slim, LG used their Advanced One-Glass-Solution (OGS) technology, which involves Dual Flexible Printed Circuits inserted between the panel and the touch film. All of this is tightly packed with a special Optical Clear Resin that enables even greater brightness levels. Worth noting is that some manufacturers have turned to use the AMOLED screens as they are thinner and theoretically use less power as they don’t require a backlight unit, but they are prone to aging, image burn/ghosting – and a generally less accurate color representation (when compared to LCD panels).
Just for comparison purposes, iPhone 4S has a total display thickness of 3.1mm, and iPhone 5 has 2.4mm on the LCD side of the story, while AMOLED goes just under 2mm (Galaxy S3/4). In a package that is smartphone, every single part of the millimeter counts as a valuable space – that could be used not only to generally thin-down the device, but to place a higher-capacity battery and/or other components instead.
“Today’s introduction of the world’s slimmest Full HD LCD panel represents an exciting advancement for the high-end smartphone segment, and is possible due to our world-class expertise in IPS and touch technologies,” said Dr. Byeong-Koo Kim, Vice President and Head of LG Display’s IT and Mobile Development Group. “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.”
LG claims that this Full HD display has a brightness of 535 nits at maximum, and performs very well in poor readability conditions, such as outdoor sunlight, etc. “Finally, measuring contrast in real-life surroundings with Ambient Contrast Ratio results in a reading of 3.74:1 based on 10,000 lux, confirming the perfect performance of the panel even in strong outdoor sunlight conditions,” company added in their press release.
According to the 2012 data from the NPD DisplaySearch, LG was the fourth largest manufacturer (12%) of smartphone/tablet screens, as Samsung Display had a 23% market share, Japan Display 15%, Sharp 13%.
