Epson is claiming another first with this world’s smallest LCD panel and they’ve started volume production of these tiny guys. The XGA HTPS-TFT Liquid Crystal Panel was specially designed for 3LCD data projectors and are up to 23% smaller in size than its predecessor, using a 0.55″ display panel.

The tiny panel can display a natural XGA (1,024 x 768) resolution, targeting projectors which can display up to 2600 ANSI lumens. Epson isn’t resting easy with this achievement though. They even have plans to push the envelope to create higher resolutions for the panels.

Getting video on a small screen is not a huge thing and it’s not new. But how about video on a screen that’s insanely small? Kopin has managed to pack a liquid-crystal display (LCD) with VGA resolution (600 x 480 pixels) onto a screen that measures just over a quarter-inch diagonally. To put that into perspective, that means that the individual color dots are 2.9 x 8.7 micrometers. A typical piece for paper is about 100 micrometers thick.

So who is going to use such a tiny screen? Who is this screen for? Kopin thinks the new screen is a stepping stone on the way to creating a screen with 2,048 x 2,048-pixel resolution the size of a postage stamp. Great HD quality…If you are an ant.

Though it likely won’t hold the title for long, Earth Trek has christened their new 90-805R projector the “world’s smallest”. It measures roughly 4 inches X 2 inches.

The device will give you a 22-inch diagonal image, though I have no idea from what distance. It sports an SD card slot and a 3.5 mm jack A/V input, built-in lithium battery good for 1-2 hours, MP4 player and built-in speaker. Nothing on price or a date yet, but expect it very soon. Not much else to see here, move along.
