HC Semitek starts building a $700 million microLED production line in Zhuhai, China

China-based HC Semitek is embarking on a 5 billion Yuan project (almost $700 million USD) to produce microLED wafers in Jinwan District, Zhuhai, China. The project will have three phases, with the first one (estimated at $275 million) has officially started last month.

HC Semitek hopes to light up the new production line in September 2024, and to start production by December 2024. When all three phases are complete, the new production line will have a yearly capacity of 58,800 microLED wafers (we do not the wafer size at this project, but we estimate these are 8-inch wafers). It is not clear from the reports, but this production line may also produce mini LEDs, not just microLEDs.

Some Apple users complain of blooming in the latest miniLED displays

Apple's latest iPad Pro tablets use a mini-LED backlit LCD (which Apple refers to as Liquid Retina XDR). While most reviews of the new display are quite positive, some users are complaining of "blooming" - the edges of bright objects on dark backgrounds tend to 'bleed' as the dimming zone is not small enough.

miniLEDs improve over LCD as they introduce thousands of dimming zones, which increases contrast and improves power consumption. The dimming zones, however, are sometimes not small enough, as some users find out, and cannot compete with an emissive technology such as OLED or microLED.
