在野外或工业应用中,测试仪器长期处在比较恶劣的工作环境中,这就要求测试仪器必须采用密闭设计。采用小键盘输入的方式无法满足严格的密闭设计的要求。本文给出一种简单实用的触摸显示设计方案,既满足了完全密闭设计的要求,又非常易于实现。 根据工作环境的要求,只要在密闭的机箱上镶 In the field or industrial applications, the test equipment in the harsh working conditions in the long term, which requires the test equipment must be sealed design. The use of keypad input can not meet the strict requirements of airtight design. This paper presents a simple and practical touch display design, not only to meet the requirements of a fully enclosed design, but also very easy to implement. According to the requirements of the working environment, as long as the enclosed chassis inlaid
