Samsung is probably the beginning of next year with tablets with cheap, flexible touch screens, which no digitizer chip need to get to work with a stylus, reports ETNews. Samsung would be a technological obstacle for relatively small metalmesh touch screens have overcome.
Until now create manufacturers for their tabletschermen use of indium tin oxide, where they are dependent on China as the largest supplier of the rare earth indium. Samsung get now for the tabletproductie about on so-called metalmesh touch screens, writes the Korean ETNews, to reduce the cost.
This type of fencing is a grid of metal wires are used, which are coated with silver or copper. These screens are already used in all-in-ones and laptops, but with a higher pixel density, as with tablets, you may experience a Moiré effect. Samsung would this problem be undone by the thickness of the wires to bring back 5 or 6 micrometers to 3 micrometers.
In addition to the cost advantage, is a positive side effect of metalmesh touch screens is that they are flexible and that there is no separate digitizer chip for stylus support, more is needed. Samsung would also the production technique for metalmesh touch screens made universal, so that they no longer have to be adjusted to the used tft-pixeltype. If the thickness of the wires for the grid to shrink to 1 micrometer, would be the technology for smartphones can be used.
At the end of this year test Samsung the reliability of the metalmesh touch screens for tablets. Then would the manufacturer in the first half of 2014, the first tablet models with screens wish to release.
