液晶显示器件(LCD)是一种新型的平板显示器件。由于它具有驱动电压低、功耗小、寿命长和能被CMOS电路直接驱动等特点,所以在使用电池作电源的小型数字仪器仪表中获得了广泛应用。随着应用范围的不断扩大,对液晶显示器件也提出了多品种化的要求。特别是用于车辆上的数字仪表及室外使用的数字仪表等应用场合,要求LCD在恶劣的低温环境中具有高响应速度。因此,对LCD的温度特性和可靠性提出了极严格的要求。目前国内生产的液晶显示器件应用温度范围能达到-10～65℃的范围就已经相当不错了。但日本东芝公司在早几年以前就已研制出能在-30～85℃范
Liquid crystal display (LCD) is a new type of flat panel display device. Because of its low driving voltage, low power consumption, long life and can be directly driven by CMOS circuits and other characteristics, so the use of small batteries for battery power digital instrumentation has been widely used. With the continuous expansion of the scope of application of liquid crystal display devices also made a variety of requirements. Especially for digital instrumentation used in vehicles and outdoor use of digital instrumentation and other applications, require LCD in the harsh low temperature environment with high response speed. Therefore, the temperature characteristics and reliability of the LCD made very strict requirements. At present, the domestic production of liquid crystal display device application temperature range can reach -10 ~ 65 ℃ range has been quite good. However, Japan Toshiba has developed a few years ago in -30 ~ 85 ℃ Fan
