Samsung Electronics is claiming a major breakthrough for the development of immersive virtual reality systems with the commercial launch of the world’s smallest pixel.

The Korean company said this week that it has developed TFT-LCDs that can fit one million pixels on to a 2.3in mini-screen of the type used in VR helmets. This density is 6.5 times that of similar units in use today.

Samsung has also increased aperture ratios from 50-60% leading to a substantial increase in brightness as well as resolution.

As well as VR helmets, the company sees applications for the new technology in digital cameras, camcorders and in the next wave of notebook PCs.

The TFT-LCDs use a multi-crystal silicon structure, and allocate individual transistors to each pixel.

Samsung claims to have overcome earlier production difficulties which required processing temperatures of 1000 degreesC or higher. By adapting manufacturing technology used by its semiconductor arm to produce DRAMs, the company has reduced the temperature to 500 degreesC.

Samsung shipped the first 1,500 TFT-LCD units to Europe last week and expects to send a similar amount each month.
