QBQS400R application field and working principle
QBQS400R is a monochrome red light emitting diode (LED) numerical and character display module that belongs to the family of display modules. It has a wide range of applications and works via principles of light transmission and reflection. It is made up of a combination of red LEDs, meaning that the module emits artificial or natural light rays when electricity is passed through its terminals.
The physical characteristics of the QBQS400R include three rows of nine characters each, a character size of 9.5mm, a viewing angle of 50° and brightness of 800mcd/m2. It has a max. operating temperature of up to 65°C and an effective voltage range from 4V to 32V.
The QBQS400R is a popular choice for applications such as industrial displays, meter displays, recording, security systems and other general purpose applications. It is a high precision device and requires minimal maintenance. Its above average viewing angle (50°) increases visibility, making it suitable for crowded areas, and its 800mcd/m2 brightness offers excellent readability during peak hours.
QBQS400R works on the principle of light transmission and reflection. It contains a dot matrix of red-coloured LEDs which are arranged in a specific way. When electricity is passed through the module, the LEDs produce a bright and visible light. The emitted light is received and directed by the reflector plate so that the characters displayed can be clearly seen from any angle.
The QBQS400R has a range of applications and is known for its superior quality, durability and performance. It is a reliable and cost-effective choice for a wide range of applications including industrial instrumentation systems, meter displays, banking systems and security systems. It offers a long service life and its superior brightness of 800mcd/m2 makes it suitable for both indoor and outdoor use.
In short, the QBQS400R display module is a highly reliable device with an impressive range of applications. It is easy to maintain and provides superior performance in different terrains. Its superior visibility and brightness make it a great choice for crowded visitors, industrial and meter displays, security systems and more.
