Qualcomm will invest an additional $1 billion in a Taiwanese computer display plant to produce its mirasol displays, according to a posting on Taiwan's Ministry of Economic Affairs website. A spokesman from the ministry clarified that the newest investment will be in addition to the joint venture Qualcomm formed with Taiwan's Cheng Uei Precision Industry Co. in 2009 to produce the displays. The very low power screens don't require backlighting, are responsive enough for animation, and should dramatically extend battery life in e-readers, smartphones and tablets.
