Qualcomm drops Mirasol
Qualcomm has dropped Mirasol, its colour e-ink display technology, saying it was difficult to manufacture.
Mirasol had the advantage of being readable in bright sunlight.
In 2004, Qualcomm paid $170m for Iridigm which invented the Mirasol technology. Earlier this year it paid about the same again to buy Pixtronix which has a MEMS-based display technology.
About a year ago, Qualcomm cancelled a planned Mirasol-based e-reader.
Qualcomm says it plans to license the technology.
