Relaying a Digitimes report, the post says Largan's chairman cited power consumption, size and transmission efficiency in calling MicroLED commercialization unlikely, while adding that AMD, Nvidia and others in the industry are procuring CW laser supply and that Lumentum and Coherent remain the EML focus.
Wow, Largan Chairman dropped a nuke and stated MicroLEDs unlikely to become viable for AI DC buildouts As for what's

Source →demian_ai: ASML's contract liabilities are the cleanest order-book proxy left
With ASML no longer publishing bookings, the analyst points to long-term contract liabilities - cash customers have paid or been billed for undelivered machines - as the cleanest demand signal, and notes short-term investments rose from about €0.9B to €4.7B over three months.
the most interesting number in $ASML results today is on the balance sheet, a line called contract liabilities.
Prepayments are harder to walk back than guidance language; they mark customers paying years ahead to hold lithography allocation.
Watch Next quarter's contract-liability balance and any reversion in short-term investments.
