Apple reportedly to adopt mini LED backlighting
Siu Han, Taipei; Adam Hwang, DIGITIMES
Apple will adopt mini LED backlighting for a 31.6-inch iMac to be launched in the second or third quarter of 2019, a 10- to 12-inch iPad to be unveiled in fourth-quarter 2020 or first-quarter 2021, and a 15- to 17-inch MacBook to be introduced in first-half 2021, according to a analyst Kuo Ming-chi at TF International Securities.
Apple is motivated by mini LED backlighting's support for wide color gamut, high contrast ratio, high dynamic range and local dimming, Kuo was widely cited by the local press as disclosing.
The backlight unit (BLU) to be used in the 31.6-inch iMac will be made of about 500 LED chips of 600 microns in size, with Japan-based Nichia to supply the LEDs, Kuo said.
Strictly speaking, this is a quasi-mini LED BLU because the chip size is much larger than those of standard mini LEDs, according to industry sources. However, the use of such a BLU will give opportunities for the supply chain to improve mini LED production in cost and yield rate, the sources noted.
But more than 10,000 mini LEDs will be needed for the iPad BLU, with the LEDs to be produced by Epistar, the LCD panels by LG Display and BLUs by Radiant Opto-Electronics, the sources said, adding the three companies will also be in the supply chain for the mini LED-backlit MacBook.
Epistar has broken into the Apple supply chain through TE Opto, a joint venture it established with Japan-based Toyoda Gosei to obtain licensed use of Toyoda's patents concerning mini LED technology, the sources indicated.
Epistar decline to comment on the report.
