Samsung is set to show off a 10.1-inch LCD panel sporting a whopping 2,560 x 1,600 resolution (300 pixels per inch), which could be available for commercial tablets as early as late 2011.
Samsung will demo the panels at SID Display Week 2011 International Symposium in Los Angeles next week, and is calling the displays the “industry’s first 10.1-inch WQXGA (2560 x 1600) format PenTile RGBW tablet display, an ultra-high resolution, liquid crystal display (LCD).”
By comparison, today’s consumer HDTVs top out at 1920 x 1080 pixels (1080 HD), and the iPad 2 sports a 1024 x 768 resolution. The Xoom and other 10.1-inch Android tablets have a 1280 x 800 resolution. The iPhone 4’s vaunted retina display is 960 x 640, but sports 326 pixels per inch (PPI) because of its smaller, 3.5-inch display.
According to Samsung VP, Dr. Sungtae Shin, the PenTile display technology, which is also found on the Nexus One smartphone, is “the only display technology that operates at 40 percent less power yet provides twice that of Full HD-viewing performance for consumers compared to legacy RGB stripe LCDs.”
PenTile display technology differs from the in-plane switching (IPS) technology found on many tablets and smartphones, including the iPad. While Samsung does provide components for Apple and its iPad/iPhone products, the use of PenTile technology, and the fact that the iPad 2 has a 9.7-inch display, means that this specific display will probably not be on the iPad 3.
LG might have that covered, however. The other Korean tech giant will also be at the show, showing off its “Advanced High Performance In-Plane Switching products” in both 7 and 9.7-inch sizes. The company claims in a release, “The ultra high resolution technology employed by AH-IPS adds a greater number of pixels than the PPI that can be recognized by the human eye at a typical distance.”
Generally, a PPI of 300 is considered to fine for the human eye to discern, implying that LG might have the iPad 3’s would-be display on display at the show.
