本文介绍在台式型与袖珍计算器较为完备的显示电路,其中着重介绍零消隐电路,三位打一标点电路,及数据规格化的显示,从电路工作分析清楚它们的工作原理和介绍它们在显示中的应用。准确清晰的显示是计算机的一个最基本的要求。从见到的国外早期产品看,它们的显示就不够完备,比如一开机就上一串零,每送一个数 This article describes the desktop and pocket calculator more complete display circuit, which focuses on the zero-blanking circuit, punctuation three punctuation, and data normalization of the display, from the circuit analysis to understand their working principle and introduce them in Display in the application. Accurate and clear display is one of the most basic computer requirements. From the early to see the foreign products to see, their display is not complete enough, such as starting on a string of zero, each sent a few
