At CES Panasonic unveiled their <a href=http://www.flatpanelshd.com/news.php?subaction=showfull&id=1326546134><b>new LED</b></a> & and <a href=http://www.flatpanelshd.com/news.php?subaction=showfull&id=1326154495><b>plasma TVs</b></a>, but they had also brought a much smaller 20-inch LCD panel, with an impressive resolution of 3840x2160 pixels – also called 4K.<br /><br /><h3>4K resolution on a 20-inch panel</h3>At CES Panasonic emphasized that they too can compete in the market for small display panels with their newly developed 20-inch panel with 4K resolution. It is not an actual product but can eventually be built into PC monitors.<br /><br /><p align=center><img class="imgresponsive" src="pictures/panasonic4k20.jpg" alt="Panasonics 4K 20-inch LCD panel"><br><i>Panasonicâ€™s 4K 20-inch LCD panel</i></p> <br />The 20.4 inch panel is based on Panasonic's own IPS Pro LCD panel technology and is the first to utilize 3840x2160 pixels – often referred to as 4K resolution – in such as small screen size. That equals a pixel density of 216 (pixels per inch). The pixel density is not as high as on the iPhone 4Sâ€™s 316 ppi LCD panel - that is often used as reference - but it is still very impressive. Panasonic also says that the panel is just 3.5 millimeters in depth.<br /><br />The LCD panel is most likely part of Panasonicâ€™s plan to enter the small-to-medium size display market. Panasonic recently <a href=http://www.flatpanelshd.com/news.php?subaction=showfull&id=1320237339><b>closed 2 TV factories</b></a> and will buy LCD-TV panels from other LCD manufactures. Instead they want to focus on manufacturing of smaller LCD panels for handheld devices, as well as plasma TVs.
