Introduction
LTS-5501AB is an LED Character and Numeric display module that is widely used in the fields of computer and communication for displaying data. It is a widely used product with very high performance, stable and reliable quality, good anti-interference ability, wide temperature range, wide luminous angle and long-time guarantee. With small size and simple structure, it is easy to install and maintain and suitable for high-density applications.
Characteristics
LTS-5501AB has a number of characteristics that make it suitable for a wide range of applications. Its working voltage range is from 4V to 15V, the operating temperature range is from - 25℃ to 70℃, the character size is 7.87 x 11mm, the viewing angle is above 170 degree, the size of the module is 35 x 20 mm. It also has reverse voltage protection and over current protection, which makes it safe and reliable in use. Moreover, it emits strong light in three different colors: red, green and yellow, so it is good for making the display clearer and vivid. Application Field
Due to its wide working voltage range, LTS-5501AB can be used in a variety of applications, including industrial automation systems, household appliances, office equipment, automotive electronics and communication systems. It is particularly suitable for applications requiring a wide temperature range, high brightness, and wide viewing angle, such as vehicle consoles and digital dashboards. In addition, it is also suitable for displays in communication systems and digital integrated circuits, such as digital signal controllers, signal transmitters and signal receivers.
Working Principle
LTS-5501AB adopts the dynamic multiplexing principle. It works through two logic interfaces. The serial-peripheral interface connects external circuitry, and the logic interface connects multiple character modules. These modules are divided into segments and each controls 8 LEDs in a row. When logic signal is applied to each segment, the LEDs in the corresponding row will emit light. These character modules are arranged in a matrix-type pattern to form the display pattern. The amount of characters that can be displayed depends on the number of character modules used in the display.
Conclusion
The LTS-5501AB LED Character and Numeric display module is a highly efficient and reliable product with a wide application range. It is suitable for industrial automation systems, household appliances, office equipment, automotive electronics and communication systems. Its working voltage range is from 4V to 15V, the operating temperature range is from - 25℃ to 70℃, the viewing angle is above 170 degree, it has reverse voltage protection and over current protection, and its character size is 7.87 x 11mm, providing great convenience for various application needs. Thanks to its dynamic multiplexing principle, LTS-5501AB can form a matrix-type array display pattern that is clear and visible, and bright emission in three colors make it fit perfectly in any situation.
