Since 2015, Apple has had its displays supplied by BOE Technology which is the world’s most significant manufacturer of laptop LCD displays. Sources based on this subject suggest that BOE Technology has been thinking about getting implicated into the suppliance of OLED screens for the Apple Watch, the iPhone and any other devices in which Apple wants to introduce this technology.
The Wall Street Journal says in a recent report that the BOE Technology company will be able to start supplying Apple with such panels from 2020. They are already displayed for the Mate RS smartphone and manufacturing some 70 percent yield panels.
In order to make money from the screen production, the 70 percent represents the low-end of efficiency required to do that. Unfortunately, it is not crystal clear how the company will manage to prove Apple with enough number of items the company will need.
Apple has only one Chinese screen supplier, and that company is BOE Technology. The Beijing city government has the largest shareholders in this state-help companies and has the right to control it.
2020 does not seem a too long a period to wait, but while working on OLED, Apple never stops seeking for better technology such as the micro-LED and quantum dot.
The construction is complicated
Just because BOE is successful in manufacturing the LCD screens, it does not mean that the story will repeat with the OLED ones. LCD screens are transmissive and use blacklight technology while OLED screens are emissive with individual light per pixel.
This results in OLED screen to be more battery saving than LCD ones. Because the OLED displays do not need blacklight, they are thinner and have a faster rate of response of 0.01 milliseconds versus LCD’s 1 millisecond. Quite a difference.
The production of LCD screens is way less complicated, and it can’t be entirely ruined by a speck of dust while being fabricated and the OLED’s cost of construction exceeds LCD’s one by a lot.
OLED screens have with water impingement while being used or produced. That means that even the smallest amount of water which touches the organic substrate of the screen can damage the display at the speed of a blink resulting in the necessity of a replacement.
Maybe because of these reasons, LG does not hurry to implement this technology onto its factories, and no rumors were heard about this possibility of LC being involved in OLED screen production.
