(Reuters) - Apple Inc <AAPL.O> is developing its own MicroLED device displays and has made small numbers of the screens for testing, Bloomberg reported on Sunday.
The iPhone maker is developing next-generation MicroLED screens at a secret plant in California and has made a huge investment for this, according to the report.
The secret project, code-named T159, is overseen by Lynn Youngs, who is in charge of iPhone and Apple Watch screen technology, Bloomberg said, citing people familiar with the matter.

Apple declined to comment.
MicroLED screens are flat panel displays that make gadgets thinner, brighter and uses less power compared with current OLED displays.
It is unlikely that the technology will reach an iPhone for at least three to five years as MicroLED screens are more difficult to produce than the current displays, Bloomberg said.
Apple currently designs chips for its mobile devices and a move into displays could hurt screen makers like Samsung Electronics Co <005930.KS>, Japan Display Inc <6740.T>, Sharp Corp <6753.T> and LG Display Co <034220.KS> in the long term.
Last year, chipmaker and Apple supplier Dialog Semiconductor Plc <DLGS.DE> acknowledged that Apple could develop its own power chips.
Sharp Corp shares fell 2.1 percent, while Japan Display's shares fell 2.4 percent and LG Display's stock lost 0.9 percent on Monday.
The move could also affect Apple's suppliers like Synaptics Inc <SYNA.O>, which makes chips used in touchscreen technology, Bloomberg said.
