    • A method (200) of controlling a liquid crystal display (LCD) (110) integrated within a sensing device for operation in cold temperature is provided. The method (200) includes providing electrical power to the LCD (110), providing an electrical signal to the LCD (110) to update displayed information, measuring (206) the ambient temperature proximate the LCD (110) and making adjustments to the power and update information supplied to the LCD (110) based on the ambient temperature. Another aspect of the invention includes a field device (10) including an LCD (110), an electronic control module (120) configured to provide power and communication signals to the LCD (110), and a temperature sensor (112) coupled to the electronic control module (120). The electronic control module (120) is configured to measure the temperature proximate the LCD (110) and control power and communication supplied to the LCD (110) based on the temperature at the LCD (110).
    • 提供一种控制液晶显示器(LCD)(110)的方法(200),该液晶显示器(110)集成在感测装置内以在低温下操作。 方法(200)包括向LCD(110)提供电力,向LCD(110)提供电信号以更新显示的信息,测量(206)接近LCD(110)的环境温度并对功率进行调整 以及基于环境温度更新提供给LCD(110)的信息。 本发明的另一方面包括现场设备(10),包括LCD(110),被配置为向LCD(110)提供电力和通信信号的电子控制模块(120)以及耦合到所述LCD 电子控制模块(120)。 电子控制模块(120)被配置为基于LCD(110)处的温度来测量靠近LCD(110)的温度并控制提供给LCD(110)的电力和通信。
