摘要

本文提出了一种设计简单、体积小的液晶驱动电路。该电路包含

施密特振荡电路和反相器，通过特定的连接方式，实现了在一定电压范围内仅用直流信号即可驱动液晶器件的功能。通过理论分析和实验测试，讨论了元件取值对该电路输出频率和波形特性的影响。测试结果表明，该逆变电路响应速度低于0.4

s。当输入电压为3 V以下时，功耗低于1 mW，且输入输出电压具有良好线性关系，可实现对液晶器件透过率的精确控制。本研究为微型化智能可穿戴设备的液晶器件驱动提供了新的技术思路。

Abstract

A simple design and small size liquid crystal drive circuit is proposed in this paper. The circuit includes an

Schmitt oscillation circuit and an inverter. Through a specific connection method

the function of driving a liquid crystal device using only a DC signal within a certain voltage range is realized. Through theoretical analysis and experimental test

the influence of component values on the output waveform characteristics of the circuit is discussed. The test results show that the inverter circuit has a response speed of less than 0.4

s. The power consumption is less than 1 mW when the input voltage is below 3 V. The input and output voltage have a good linear relationship

which can realize precise control of the transmittance of the liquid crystal device. This research provides new technical ideas for driving liquid crystal devices in miniaturized smart wearable devices.
