Apple is investing a huge amount in making of next-generation MicroLED screens. Since the MicroLED displays are more hard to produce than OLEDs, Apple has even taken into consideration killing the project altogether past year. It's a tall order and Apple nearly gave up on it but recent progress sparked enough hope that it's making quite the fuss at Apple HQ. The company's move into display showcases long-term potential to hurt range of suppliers from screen manufacturers such as Japan Display Inc., LG Display, Samsung Electronics Co., which manufacture chip-screen interface.
Mass production MicroLEDs will need new manufacturing equipment. By the time this technology comes to life, something else would have been introduced in the market. We're talking several years in the future, but development work is well underway, and early prototypes are described as mighty encouraging by "people familiar with the situation". For testing purposes, Apple is making a small number of screens starting with the Apple Watch at a manufacturing facility near its California headquarters. Currently, the company is working on further improving the technology. Samsung, one of the biggest OLED makers, is already having problems looking for buyers now that Apple is reportedly cutting iPhone X orders in half.
The iPhone X uses an OLED screen panel from Samsung while the Apple Watch uses a display from LG. Last year Apple made a decision to sideline the project. This will be the first time when Apple will design end-to-end screen itself. As of now, the Santa Clara facility has been able to manufacture only a handful of fully operational microLED screens which are the size of the Apple Watch that's under 2-inches diagonally.
The report also mentions of another facility that houses technology that handles LED-transfers, a process in which individual pixels are placed into a microLED screen. Developed under the code name T159, the MicroLED screens are said to be notably brighter and superior in color accuracy to OLEDs, and should enable Apple to build thinner, lower-powered devices.
