T61 Screens

Has anybody had problems with T61 screens ? We have now had about 10 smash in the last month!!!!!

 

OT: what is a custom crafted man bag?

 

Hi,

My mate who works in a hospital has also experienced high failure rates of TFT screens on heart rate monitors. I believe it's due to the new manufacture processes being used in the last year.

TFTs can be made using a wide variety of semiconductor materials. A common material is silicon. The characteristics of a silicon based TFT depend on the crystalline state. That is, the semiconductor layer can be either amorphous silicon, microcrystalline silicon, or it can be annealed into polysilicon.

Other materials which have been used as semiconductors in TFTs include compound semiconductors such as cadmium selenium (CdSe)and metal oxides such as Zinc Oxide. TFT's have also been made using organic materials (referred to as an Organic TFT or OTFT).

By using transparent semiconductors and transparent electrodes, such as indium tin oxide (ITO), some TFT devices can be made completely transparent.[clarification needed]

Because the substrate cannot withstand the high annealing temperature, the deposition process has to be completed under relatively low temperature. Chemical vapor deposition, physical vapor deposition (usually sputtering) are applied. Also, the first solution processed transparent TFTs (TTFTs), based on zinc oxide were reported in 2003 by researchers at Oregon State University.

Meanwhile, Portuguese laboratory CENIMAT, Universidade Nova de Lisboa, discovered a way of producing TFT at room temperature, having produced the world’s first completely transparent TFT at room temperature. CENIMAT also developed the first paper transistor, which may lead to applications such as magazines and journal pages with moving images.



Hope this helps.
