Taiwan-based projector manufacturer Vivitek has said it plans to ship 300,000 DLP projectors globally this year - an increase of 80 per cent on 2010.

The announcement follows concerns that DLP chips are in short supply after two factories belonging to DLP chip manufacturer Texas Instruments (TI) were damaged by the earthquake in Japan.

One of the plants is expected to be fully operational by mid April, while the other will run at part capacity before returning to normal in July, according to Vivitek Taiwan.

News of TI's quake-damaged factories sparked a rush on available DLP chips, with customers competing to take deliveries earlier than scheduled. Large brands, including Vivitek, have been given priority over smaller customers, Vivitek Taiwan said.

The projector specialist manufactures a range of digital projection and display products, which are sold through authorised dealers, distributors, retailers and system integrators.

The company, which opened an exhibition centre in Taiwan's capital Taipei on March 31, is ranked as the third-largest brand in China for DLP projectors and eighth in terms of overall projector shipments to China during 2010.

Vivitek has indicated it will continue to build its presence in global markets including China, the United States, Europe and India in a bid to become one of the top ten projector brands in the world.
