SAMSUNG Electronics Introduces World`s Highest Resolution TFT LCD

Seoul, Korea, June 2, 1997 - Samsung Electronics Co. Ltd. has used low-temperature, multi-crystal silicon TFT LCD technology, an area that has received a great deal of attention in the industry lately, to develop a TFT LCD with 430,000 pixels per square inch.

Samsung Electronics has applied super-precise processing technology which is used in the development of semiconductors to work with the low-temperature, multi-crystal silicon TFT-LCD. Samsung has created the world`s smallest pixels, with a pitch of 23.5` m x 61.5` m, and can fit one million of them on a super-small 2.3` screen. Conventionally with an amorphous silicon, no more than 300,000 pixels can be placed on a screen of this size, with also an aperture ratio of 50. However, this new device by Samsung Electronics` boasts an aperture of 60, which means better quality in brightness.

Samsung Electronics’ new TFT LCD has 6.5 times more pixels per inch than the current market leader. Also, its single panel to load all three primary colors, makes it technologically more sophisticated and far more adaptable than products made by other major competitors.

The ICs can be built into the panel while a silicon film is placed on top of the TFT panel. This method will make possible the development of high-value-added system-on-panel products. Moreover, the higher aperture ratio will allow Samsung to make screens with the same resolution, and with less consumption power. Electricity flows much faster through the multi-crystal silicon structure, and shortens response time when constructing large-screen TFT LCDs. The biggest obstacle facing manufacturers so far with the multi-crystal silicon products is the need for processing at temperatures of 1,000 C or higher. Samsung has developed a production process that can be carried out at 500 C or lower.

The super-small 2` to 3` TFT LCD screens currently under development can provide resolution quality that is better than any other screen available. Thus, it will be used in video projectors, virtual reality helmets, digital cameras and digital camcorders. Meanwhile, some major players have already gone into the development of a 12.1` version for notebook PCs. Therefore, when the larger versions are available, they are expected to quickly replace conventional TFT LCDs for use in both notebook PCs, and desktop monitors.

SEC now has the necessary basic technology for low-temperature, multi-crystal TFT LCDs. Thus the company will aggressively invest money and personnel to develop its own products for notebook PCs, with plans to have mass production capability by 1999.
