AOTO Opens New MicroLED Production Facility in Huizhou
2026-10-01 · via AV Magazine
Chinese display manufacturer AOTO has opened a new microLED production facility in Huizhou, adding dedicated manufacturing capacity for ultra-fine-pitch LED displays. For buyers and integrators tracking the fine-pitch LED market, this signals another major vendor scaling up to meet demand for smaller pixel pitches in control rooms, corporate lobbies, and high-end retail and broadcast installations.
According to the company, the facility covers a pixel pitch range of 0.3mm to 1.5mm and supports both chip-on-board and chip-on-glass packaging methods. AOTO says chip placement accuracy at the plant reaches ±5 μm, a tolerance aimed at the kind of seamless image uniformity buyers expect at sub-millimetre pitches where panel joints and colour consistency become harder to hide.
The company says more than 95% of production is automated, with digital process control layered in to standardise output. AOTO reports a 99.99% pass rate on finished products through its quality testing, though the announcement does not detail what that testing regime covers or how it compares with pass rates at its existing facilities.
Clean room conditions and dual-use capacity
The plant runs under Class 1,000 clean room conditions with controlled temperature and humidity, standard practice for microLED manufacturing given how sensitive the chips are to contamination. AOTO also notes electrostatic discharge protection built into the facility, intended to stop static buildup from damaging components during assembly.
AOTO positions the centre as supporting both volume manufacturing and customised production runs across its microLED and miniLED lines, suggesting the company wants flexibility to serve large rental and installation projects alongside smaller bespoke orders without separate tooling.
What this means for operators and integrators
For digital signage operators and AV integrators, new fine-pitch capacity from a major Chinese manufacturer points to likely downward pressure on pricing and lead times for sub-1mm pitch LED, an area that has been constrained by yield and precision challenges industry-wide. AOTO's emphasis on automation and placement accuracy speaks directly to the quality concerns that have historically made ultra-fine-pitch LED a harder sell than LCD for some applications, particularly where viewing distances are short.
The announcement does not specify production volume targets, investment figures, or a timeline for when output from the new facility will reach the market. It also does not say how this capacity expansion fits into AOTO's broader manufacturing footprint or whether it replaces or supplements existing lines. Buyers evaluating microLED suppliers will want those details, along with independent verification of the quality claims, before treating this as a signal of imminent price or availability shifts.

The production centre, which adds dedicated capacity for ultra-fine-pitch LED displays, introduces automated production lines and digital process control to help improve flexibility and consistency.
China-based display manufacturer AOTO has opened a microLED production facility in Huizhou.
The production centre introduces dedicated capacity for ultra-fine-pitch LED displays with a pixel pitch of between 0.3mm and 1.5mm.
The facility supports chip-on-board and chip-on-glass packaging, offering a chip placement accuracy of ±5 μm. More than 95% of production at the plant is automated, with 99.99% of finished products passing AOTO’s quality testing.
AOTO’s new centre gives the company greater control over precision, consistency and production flexibility, as LED displays move toward increasingly fine pixel pitches.
The facility operates under Class 1,000 clean room conditions, with controlled temperature and humidity. Protection against electrostatic discharge prevents static electricity from building up and affecting the sensitive microLED components.
The facility is set up for both volume manufacturing and customised production across AOTO’s microLED and miniLED portfolio.
