As the demand for 3D TV continues to grow in China, competition among vendors is set to become more intense.

With sales of 3D TVs accounting for over 10% of LCD sales during the Labour Day holidays in early May, analysts agree that this market share will increase.

The China Electronic Chamber of Commerce (CECC) estimates that some 5 million 3D TVs will be sold by the end of 2011.

Meanwhile, consulting firm China Market Monitor Co (CMMC) said that 3D TVs would take about 12% to 15% of the share in the panel television sector by the end of 2011, and Displaybank estimated that more than 86% of plasma TVs will support 3D technology by the end of 2013.

International panel makers are bringing their 3D technology to China in a bid to capture a share of the market.

LG Display (LGD) introduced its Film-type Patterned Retarder (FPR) technology to the Chinese market, to compete with Shutter Glass (SG) technology. The company claims it is more advanced and has lower production costs. LGD also chose to co-operate with several large TV manufacturers including SkyWorth and Panasonic to increase market share in the 3D sector. According to CMMC, FPR technology occupied some 45% of market share in April, an increase from zero in less than five months.

Meanwhile, Samsung said it would stick with SG technology and formed an alliance with TV manufacturers including Sharp and Sony to secure their market shares in China.

However, analysts say consumers are more interested in image quality and prices than in the technology. They say the most important thing for vendors is to lower their prices, and for broadcasters to introduce more 3D content.
