A new report by Nikkei Asia details Apple's microLED production plans

Apple's microLED projects and goals have been reported and rumored many times in the past, and now the respected Nikkei Asia newspaper posted an interesting article with new details of Apple's microLED plans. Some parts of this plan were already published by other reporters, note.

According to the new report, Apple is aiming to get more involved in display manufacturing, to increase its control over its supply chain, and reduce its reliance on Samsung Display specifically. Apple has decided, therefore, to handle the LED transfer (pick-and-place) process by itself, at its R&D facilities in Longtan, Taoyuan, Taiwan.

ams Osram: microLED is one of our key initiatives, but the market is a few years away

In a recent conference call, Alexander Everke, the CEO at LED and sensor developer ams Osram, remarked that microLED is one of the company's key initiatives.

The microLED market, according to Everke, is "clearly a few years away", but the company plans to invest in the technology to make sure it stays ahead of the curve, as it wants to position itselff as the clear microLED leader.

Kyocera and OSRAM suggest hybrid PWM-current driving for microLED displays

Kyocera and OSRAM have jointly designed a new hybrid current and PWM driving technology for microLED displays. The two companies says that this new driving scheme can be used to avoid using lower pixel currents through microLED chips, which reduces the deviation of the luminance and the color shift at lower grayscale levels.

ALLOS Semiconductor sells its HPE and RF business, to focus on the microLED market

German-based GaN-on-Si developer ALLOS announced that it has sold its high-power electronics and RF business to AZUR SPACE. ALLOS will now focus its business on the microLED display market.

ALLOS Semiconductors developed its GaN-on-Si epiwafer technology for both high power electronics and Micro LED applications, but the time has come to focus on one market. The company says its 200 and 300 mm epiwafer technology is crucial in meeting the uniformity, crystal quality and manufacturability requirements of the novel Micro LED display applications.

ALLOS and Veeco up-scale GaN-on-Si microLED production technology to 300 mm wafers

German-based GaN-on-Si developer ALLOS has applied its technology to large 300 mm epiwafers. ALLOS says that scaling up to 300 mm wafers enables higher production efficiencies and thus lower costs. ALLOS estimates that the higher area utilization alone accounts for a cost advantage of 40% compared to standard LED wafers. Standard 300 mm silicon line tools also offer higher production uniformity and yield.

ALLOS demonstrated the 300 mm scale-up using a reactor made by Veeco who announced selling the first 300 mm GaN reactor to a leading-edge semiconductor fab just some month ago and also showed 300 mm wafer data at CES. ALLOS reports a wavelength uniformity of consistently below 1 nm and "all other production requirements like bow of
