Amazon has bought Liquavista, a company that makes 'electrowetting' colour displays.
The online retail giant acquires Liquavista, a screen tech company that made a splash at the 2011 CES with its color e-reader.
The company is reportedly trying to sell Liquavista, a firm it acquired in January 2011, for less than $100 million.
Liquavista's full-color e-reader appears to be aimed squarely at magazine and newspaper reading.
