Apple acquired LuxVue Technology, a little-known start-up that makes screens displays using next-generation light-emitting diode technology called micro-LED.

Apple could possibly use these micro LED displays in future versions of the Apple iWatch, or in some other wearable devices, the displays apparently have very low power requirements, and provide improved brightness.

LuxVue has filed a handful of patents for micro-LED technology, which promises displays that are brighter and use less power than current screens. The company, which is based in Santa Clara, Calif., has raised more than $43 million, including a $25.2 million funding round in December.

Apple are expected to launch their first Apple iWatch in September, along with the iPhone 6 and Apple iOS 8, we are not expecting to see any technology from LuxeVue used in the first generation iWatch.

We recently heard that Apple had started production of the iWatch, and that the device is said to feature a flexible OLED display which may be made by LG for Apple.

It is also possible that Apple could use this new micro LED technology in other devices, as it is designed to be very energy efficient.

Apple has yet to confirm the purchase of LuxeVue, the company did tell TechCrunch that they buy a number of small companies from time to time, but generally do not discuss the purchases.
