随着数字仪表的不断发展,对各类数字显示器件提出了更高的要求,也促进了显示器件本身的迅速发展,尤其是液晶显示器件以它独具的驱动电压低、功耗小、寿命长等优点在小型数字仪表中居于领先地位。本文对液晶显示器件的三线多路驱动方法及其电路进行了详细地阐述和分析。当前我国各集成电路厂家尚未生产出动态驱动液晶显示器件的大规模集成电路,本文提供了利用目前国内生产的中小规模集成电路元件来动态驱动该类器件的具体电路和方法,对使用和生产液晶显示器件的厂家,具有一定的实用和参考价值。
With the continuous development of digital instruments, all kinds of digital display devices put forward higher requirements, but also contributed to the rapid development of the display device itself, especially the liquid crystal display device with its unique drive voltage, power consumption, life expectancy Long advantages such as small digital instruments living in the leading position. In this paper, the liquid crystal display device three-wire multi-channel driving method and circuit are described and analyzed in detail. At present, each IC manufacturer in China has not yet produced a large-scale integrated circuit that dynamically drives liquid crystal display devices. This document provides specific circuits and methods for dynamically driving such devices using the current domestic production of small and medium-scale integrated circuit components. The specific circuits and methods for using and producing liquid crystal Display device manufacturers, with some practical and reference value.
