Display-centric blog oled-display.net is reporting that Samsung’s mobile display division will double the lifespan of its much sought-after AMOLED displays (from 50 kilowatt hours to over 100 kilowatt hours) while decreasing power consumption (from 62 watts to under 30 watts) by the end of 2011. The blog reports that: “By increasing of substrate size from 4 to the new 5.5 gen line the number of same size panels produced from one substrate increase and it will bring more production efficiency also for larger OLED-Television devices.” Sounds like great news for mobile phone battery life and handset longevity, let’s just hope Samsung can crank these displays out fast enough for the manufacturers who need them.
