17 March—AU Optronics Corp. (AUO), Taiwan’s largest manufacturer of thin-film transistor liquid crystal display panels (TFT-LCD), submitted an application on 15 March to the government confirming its plan to build a 7.5-generation plant in eastern China. It thus became the first Taiwanese LCD maker to take advantage of its own country’s lifting of the ban on building TFT-LCD fabs in China.

YOU'VE PROBABLY PLAYED hundreds, maybe thousands, of videos on your smartphone. But have you ever thought about what happens when you press “play”?

The instant you touch that little triangle, many things happen at once. In microseconds, idle compute cores on your phone's processor spring to life. As they do so, their voltages and clock frequencies shoot up to ensure that the video decompresses and displays without delay. Meanwhile, other cores, running tasks in the background, throttle down. Charge surges into the active cores' millions of transistors and slows to a trickle in the newly idled ones.
