Intel promises at least four hours longer battery life with 1W screen panels

Intel has developed a 1W screen panel together with the screen manufacturers Sharp and Innolux. In collaboration with other technologies, Intel’s Low Power Display technology should lead to a battery life that is four to eight hours longer.

Intel announced its Low Power Display at Computex 2018. The company demonstrated a Dell XPS 13 with the display technology, which had a battery life of 25 hours and 14 minutes when measured during continuous video playback. The same laptop would have a battery life of 20 hours without the technology.

Intel also claims to have measured a battery life of 28 hours, on a system with a Core i7-8550U with UHD 620 GPU, Intel 600p SSD and Windows 10. Again, this involved video playback, with a screen brightness of 150cd/m².

The systems use a full HD screen that Intel has developed together with Innolux and Sharp. The companies would have reduced the consumption of such a screen from 2W to 1W. The companies gave no further details on the Low Power Display technology, but no compromises were made in terms of quality.

It is expected that Intel will advise the specification to manufacturers of laptops and that there will be cooperation with Intel’s GPU integrated in the processor. It is not the first time that Intel has partnered with screen manufacturers to reduce screen consumption: in the past, Intel developed the Panel Self Refresh technology, which LG started using in 2011. The laptop saves the last displayed frame in memory in the screen. With a static image, the system can display this frame and put the GPU in an energy-efficient state faster and more often.
