Share prices of touch panel maker Wintek suffered a sharp decline on December 15 on the Taiwan Stock Exchange (TSE) amid market reports stating that the touch-panel maker's December 2010 revenues will be lower than its projection.

Wintek's shares dropped NT$3.10 or 5.4% to NT$54.60 in the mid-session before closing at NT$55.10, according to market data. Wintek declined to comment on market reports as the company is in the silent period for its upcoming GDR (global depositary receipt) issue.

Wintek posted revenues of NT$8.8 billion (US$294.31 million) for November, and company chairman Hyley Huang predicted earlier that revenues will top NT$9.5 billion in December. Huang even forecast revenues of over NT$10 billion a month through the entire year of 2011.

Some industry sources have estimated that Wintek's December revenues will fall short of its projection due to a weakening of the touch-panel market. However, Wintek insisted that touch-panels will continue to grow moving forwards.

In other news, Wintek said that it has secured land for construction of an LCM plant in Vietnam, but details of the investment plan are not yet available.
