AU Optronics has stopped processing operations in its three plants in Taiwan after the region was hit by an earthquake.
Workers at three factories in the northern part of the island have been sent home after Poseidon voiced his displeasure yesterday.
AU Optronics is the world's number four flat panel maker and it is uncertain how much capacity would be affected.
As quakes go, it was not a particularly bad one. It had a preliminary magnitude of 4.9 and there were no casualties or damage immediately reported. Stopping all three plants is quite unusual. So far there is no indication how long the plants will remain closed.
