松下电子元件有限公司将重点放在制造和销售白模式超扭曲向列型液晶显示(STNLCD)和带引线的扭曲向列型液晶显示(TN LCD)上。该公司研制的白模式STN LCD的尺寸为640×400点,相当于12英寸CRT,它通过采用STN板和相位板的双层复合材料并通过改进液晶材料,使该显示的最低对比度为1∶15,视场角为65。甚至更大,驱动占空比1/200,节距0.36×0.36毫米,点尺寸0.32×0.32毫米,响应时间为200毫秒。由于它装有COF,该显示的外部尺寸为300×178×24毫米。它采用冷阴极管作背光源。去年年底样品投放价为每台15万日元,今年春季投入批量生产,月产量为2万台。
Matsushita Electric Components Co., Ltd. will focus on the manufacture and sale of white mode super twisted nematic liquid crystal display (STNLCD) and twisted nematic liquid crystal display (TN LCD). The company developed a white-mode STN LCD measuring 640 x 400 dots, equivalent to a 12-inch CRT by using a two-layer composite of STN and phase plates and by modifying the liquid crystal material so that the lowest contrast of the display is 1: 15, field of view of 65. Even more, driving duty cycle 1/200, pitch 0.36 × 0.36 mm, point size 0.32 × 0.32 mm, response time of 200 ms. Due to its COF mounting, this display has an external dimensions of 300 × 178 × 24 mm. It uses a cold cathode tube for backlighting. The end of last year put the sample price of 150,000 yen per unit, put into mass production this spring, monthly production of 20,000 units.
