数显液晶模块(见图1所示)是一种由段型液晶器件与专用集成电路组装成一体的功能部件。常见的数显液晶模块有计数模块、计量模块和定时模块几种。1.计数模块计数模块由不同位数七段型液晶显示器件与译码驱动器(或再加上计数器装配成的计数显示部件)组成。目前国内市场上的主要产品有:由CD4055译码驱动器驱动单位液晶显示器件显示模块;由ICM7211、ICM7232、CDl4543、UPDl45001、HD44100等集成电路与相应配套的液晶显示器件组装成的计数模块。这些计数模块分别有4位、6位、8位、10位、12位、16位不
Digital LCD module (see Figure 1) is a segment LCD components and integrated circuits assembled into one of the functional components. Common digital LCD module counting module, the number of modules and timing modules. 1. Counting Module The counting module is composed of seven-segment liquid crystal display devices with different digits and decoding driver (or count display part assembled with counter). At present, the main products on the domestic market are: LCD display module driven by CD4055 decoding driver unit; and counting module assembled by integrated circuits such as ICM7211, ICM7232, CDl4543, UPDl45001, HD44100 and the corresponding liquid crystal display devices. These counting modules have 4, 6, 8, 10, 12, 16 respectively
