Abstract: A method (200) of controlling a liquid crystal display (LCD) (110) integrate d 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).
