极端温度液晶显示模块的选择
工业,非汽车运输和军事部门,除其他外,往往需要液晶字符或图形显示,可以在极端温度环境下运行。通常情况下,标准的LCD字符和图形模块+ 50°C.然而提供0°C的温度范围内,一些显示器厂商提供极端温度模型与工作温度- 40°C+80或+85°C.也有多种选择的标准版本,范围从20°C + 70°C.
虽然工作温度范围规范显然是极端热/冷环境显示的最重要的特点之一,工程师还需要记住其他几个因素时,选择这些应用程序的显示。这些因素包括视觉显示要求,功耗,当然,成本。
One of the first things that designers need to consider is the end use. The applicaTIon is going to dictate the type of display required — what are the environmental condiTIons; what type of informaTIon will be displayed — characters (numbers or letters) or graphics — is power consumpTIon a factor, and what performance trade-offs can be considered versus cost.
The operating environment of the LCD display — UV exposure, moisture, humidity, temperature — all of these factors are important when designing an extreme temperature display into an application, said Yasoob Ahmed, director of engineering at ITW Electronic Component Solutions.
