The company has also not yet determined if the new plant will be a 7.5G factory or 8G, which would use even larger sheets of glass. Construction on the plant started earlier this month.The new project should ensure that prices of LCD TVs continue to fall to levels more and more consumers are able to afford, since the screen is the most expensive part of an LCD TV. The new plants reduce production costs by increasing the volume of screens a company can cut from each sheet of glass.In addition, the allure of the LCD TV market has caused cutthroat competition among LCD screen producers such as Chi Mei and Samsung Electronics Co. Ltd., causing them to increase production at a faster rate than consumers can snap up LCD TVs. The result has been a glut of LCD screens recently, which has caused prices of the screens to drop.Chi Mei plans to spend NT$100 billion (US$3.09 billion) on plant construction and production line equipment this year, compared to NT$62 billion last year. The company's newest plant is being built in southern Taiwan at the Kaohsiung Science Park.Earlier this year, Samsung and LG.Philips LCD Co. Ltd., two of the world's largest manufacturers of LCD panels, both started commercial production at brand new LCD factories. On Wednesday, S-LCD, the LCD panel manufacturing joint venture of Sony Corp. and Samsung, said it plans to invest a further 222 billion won (US$238 million) to expand production at its factory in Tangjeong, South Korea.
