View source for Intel Display Power Saving Technology

'''Intel Display Power Saving Technology '''or '''Intel DPST '''is an [[Intel]] [[backlight]] control technology. Intel claims that [[Flat panel display|display]] take up most power in mobile devices and reducing [[backlight]] linearly affects energy footprint. Intel DPST technology aims to adaptively reduce backlight brightness while maintaining satisfactory visual performance. The Intel DPST subsystem analyzes the image to be displayed and it uses a set of algorithms to change the [[Colorfulness|chroma value]] of [[pixels]] while reducing the [[brightness]] of backlight simultaneously such that there is minimum perceived visual degradation. When the frame to be projected and the frame being projected has considerable difference a [[software interrupt]] is asserted and new chroma values for pixels and brightness values are calculated. The current version is Intel DPST 6.0. Intel claims that the current DPST version reduces backlight power by 70% for [[DVD]] workloads.
