Apple's ambition is to make in-house displays just like they have produced their own in-house chipset for the past several years.
Apple's focus on MicroLED is due to the benefits offered, notably they create thinner, brighter, and less power-hungry displays without the downsides of OLED (limited life span, brightness).
MicroLED screens are better than OLED screens because there are slimmer, more energy efficient, and brighter than current technologies as they use a special type of light-emitting LEDs. The company is now building engineering samples at a plant in California, but this is considered too small for the commercial manufacturing of the panels.
Universal Display stock hit an all-time high of 209 on January 19, before heading south. Apple also uses OLED screens in its current Apple Watch smartwatches. The iPhone X, Apple's first OLED phone, uses Samsung technology.
According to Bloomberg's report, Apple almost shelved the project a few years back but the company's engineers made progress and the tech is now at an "advanced" stage. Last year, we saw the iPhone X delay a little due to some production issues.
For this, Apple acquired a start-up called LuxVue in 2014 and followed up with gradual efforts to see how things pan out.More news: Live updates from Tiger Woods' Round 4 at the Arnold Palmer Invitational

The secret screen-manufacturing development marks the latest move by the Cupertino tech giant in building now outsourced technology in-house.
It's unlikely that the technology will reach an iPhone for at least three to five years, the people say. Japan Display, Sharp Corp., and Samsung all dropped due to their association with Apple.
MicroLED is considered the next major leap in screen technology. However, Bloomberg says, manufacturing is likely to move out of the current facility if the MicroLED project becomes commercialized further. An Apple Watch with a MicroLED display is still years out.
For future devices, Apple may stop relying on outside suppliers for its displays. MicroLEDs comprise millions of discrete pixels, on the basis of screen size.
The Apple facility is now assembling prototype MicroLED screens for attaching the screens to the glass.
The 62,000-square-foot manufacturing facility is located in Santa Clara, California.
