LED Character and Numeric

What are the ‌Core Features of LED Character and Numeric?‌

 

‌Display Type‌: mainly 7-segment digital tubes, supporting the display of numbers, some letters, or symbols‌;

 

‌Configuration parameters‌: including character size (such as 0.3 inches to 0.57 inches‌), display digits (1 or 2 digits‌), common cathode/common anode pin configuration‌, etc.;

 

‌Electrical characteristics‌: forward voltage range is usually 2V–2.1V, test current is 20mA‌, power consumption is less than 75mW‌;

 

‌Physical characteristics‌: module size is compact, and packaging forms include SMD, DIP, etc.
