At the conference, Intel said they were working on a new Low Power Display Technology
that combined more efficient energy use with lower power consumption to increase the battery life of a 13-inch display. For some devices, that could lead to a battery that lasts longer than a full day. "The display consumes the most battery in a device, and one way we're working to enable all-day battery life is by co-engineering the new Intel Low Power Display Technology, featured in a one watt panel manufactured by Sharp and Innolux, which can cut LCD power consumption by half," Gregory Bryant, senior vice president and general manager of the Client Computing Group at Intel, said in a press release. "Through continued innovation with the industry, we expect to deliver an additional four to eight hours of local video playback - that means battery life could be up to 28 hours on some devices."
In a presentation at the conference, Intel played a time-lapse video showing the laptop operating for 25 hours. Bryant also added that changes in hardware and new Intel GPU software allow for the lower battery power use. According to the release, lighting up the screen is the most energy-consuming task laptops perform, and their system takes measures to address this while keeping screen brightness relatively high. With the help of Sharp and Innolux, their new screens use half of the energy they used to.
