解析LED数码显示管的结构
本文中TOPPOWER来为大家介绍LED数码显示管的结构,希望对各位工程师朋友有所帮助。
LED数码显示管是一种常用的字符显示器件,能与CMOS、TTL等集成电路直接配合,作静态、动态扫描显示之用。图12-33(a)是LED数码显示管的实物图,图 12-33(b)是LED数码显示管的内部结构。它实际上是由8个发光二极管构成的,其中7个发光二极管排列成“8”字形的笔画段,另一个发光二极管为圆点形状,安装在显示器的右下角作为小数点使用。通过发光二极管亮暗的不同组合,从而可显示出0~9的阿拉伯数字符号以及其他能由这些笔画段构成的各种字符。
LED数码显示管的内部结构共有两种不同形式,一种是共阳极显示器,其内部电路见图 12-34(a),即8个发光二极管的正极全部连接在一起组成公共端,8个发光二极管的负极则各自独立引出;另一种是共阴极显示器,其内部电路见图12-34(b),即8个发光二极管的负极全部连接在一起组成公共端,8个发光二极管的正极则各自独立引出。LED数码显示管中的发光二极管共有两种连接方法:
共阳极接法。把发光二极管的阳极连在一起,使用时公共阳极接+5V,这时阴极接低电平的段发光二极管就导通点亮,而接高电平的则不点亮。
共阴极接法。把发光二极管的阴极连在一起,使用时公共阴极接地,这时阳极接高电平的段发光二极管就导通点亮,而接低电平的则不点亮。
驱动电路中的限流电阻器R,其阻值通常根据LED的工作电流计算而得到。
LED数码显示管正常发光时,每段工作电流为5~10mA,每段极限工作电流20mA,全部笔画点亮时的电流为35~70mA,正向电压<2V。LED数码显示管的发光颜色大多为红色,也有绿色、橙色的。数字时钟、数字仪表以及其他数字显示中都大量采用LED数码显示管。
为了显示数字或符号,要为LED数码显示管提供代码,因为这些代码是为显示字形用的,因此称之为字形代码。
七段发光二极管,再加上一个小数点位,共计8位代码,由一个数据字节提供。各数据位的对应关系如表12-1所示。
LED数码显示管的字形(段)代码见表12-2。在程序设计时,表12-2作为表格存入存储单元,通过改变表格内容使显示字形变化。所以,用软件译码字形显示比较灵活。
LED数码显示管的作用是显示字符。例如,在时钟电路中显示时间,在测量、控制电路中显示结果,在计数电路中显示数字。
选用LED数码显示管时,应根据具体要求选择合适的型号规格。外形尺寸、发光颜色发光亮度、额定功率、工作电流、工作电压及极性等均应符合应用电路的要求。选用LED数码显示管的极性(共阳型或共阴型)应与其译码驱动电路相匹配。通常用LED数码显示管型号后面的末位数字或型号前面的两位字母来表示显示管的极性。不同厂家生产的LED数码显示管,极性的标注方法也不相同,这一点在选用时应特别注意。

一文详解二极管压降的定义、数值及影响因素
二极管压降是二极管在正向导通和反向截止状态下电压降低的现象。其数值取决于多种因素,包括材料、类型、工作电流和温度等。在实际应用中,了解二极管的压降特性对于电路设计和分析具有重要意义。对于需要低功耗和高效率的电路来说,选择压降较小的二极管尤为重要。

解析OLED的基本原理
LED 是有机发光二极管(Organic Light-Emitting Diode)的缩写,是一种先进的显示技术。与传统的液晶显示技术(LCD)不同,OLED显示器不需要背光模块,因为每个像素本身可以发光。目前,OLED技术广泛应用于手机、平板电脑、电视、可穿戴设备等高端显示产品上。

如何测试晶振是否工作正常?
可以使用以下三种方法测试晶振是否工作正常: 1. 示波器检测法:晶振在激发时会产生正弦波,如果在时钟引脚上查看代表正弦波的波形是合适的。 如果时钟不能正常工作,请更换晶振。 当显示器进来时没有高压症状,用示波器检查晶体发现波形非常不稳定,更换微处理器解决了无高压问题,晶振波形显示完美的正弦波。 2. 频率计数器检测法:必须在设备电源“打开”时进行测量。 将仪表或频率计数器的探头放在晶振引脚上并读取测量值。 确保使用的频率计数器表的范围高于正在检查的晶振频率。 如果晶振为8 mhz,那么使用的仪表应该具有能够检查该频率的范围。 假设晶振的读数为2.5 mhz,那么可以知道晶振不能正常工作,需要更换。 3. 测试电路检测法:显示器件能够显示字符和符号,在电子设备中的应用日益广泛。 以上三种方法都可以用来测试晶振是否工作正常,具体方法可能会因不同的设备和应用场景而有所不同。
