BOE's AMOLED production volume still low as the company faces IC supply constraints

In February 2022 it was reported that BOE failed to secure enough driver ICs, and had to reduce its AMOLED production volume. According to new reports from Korea, BOE is still facing IC supply issues, and it is estimated that it AMOLED volume will remain lower than expected at least until May.

The new report suggests that beyond the IC supply constraints, BOE is also suffering from low yields at its new B12 fab in Chongqing, lower than what it hoped for in 2022.
