LB-502MD

Introduced in 2019, the LB-502MD is a medium-sized LED display module that offers a wide range of applications. It consists of 80 individually addressable LEDs arranged into 10 columns and 8 rows, powered by a 3.3V/5V TTL interface. The LED display module can be used in various applications such as in industrial, automotive, and medical fields.

Characteristics of LB-502MD

The LB-502MD uses an active-low constant-current drive design and can be controlled through low voltage logic levels. Each LED in the display module has a 2.54mm pitch making it suitable for automated manufacturing. The display module also offers a wide range of display options, such as positive/negative display modes, adjustable brightness and contrast, as well as different color options for the LEDs -- red, green, and yellow.

The display module also features ESD protection so that it can be safely used for applications in harsh environments. The LEDs have a viewing angle of 80 degrees and can be operated in temperatures ranging from -40°C to +85°C. The module also has IP67 ingress protection and has been tested to withstand wavelengths of 405nm-660nm. Additionally, the LED display module is FCC and CE approved, making it suitable for use in many different types of areas.

Working Principles

The LB-502MD uses low voltage logic levels to control the LEDs. When a low logic level is applied to a particular column and row combination, the corresponding LED will turn on. By setting the logic levels of each column and row combination, the desired pattern can be shown on the display module. The LEDs can be adjusted for brightness, contrast, and color options through the use of software.

The LED display module also features overcurrent protection, ensuring that the LED does not draw too much current and cause damage to the module. It also supports operation in many different temperature ranges, so it is suitable for use in a variety of environments.

Applications of LB-502MD

The LB-502MD can be used in a variety of applications in the industrial, automotive and medical fields. It can be used for industrial applications, such as status indicators, message displays and warning signs. It can also be used in automotive applications, such as dashboards and indicator displays. Additionally, it can be used in medical applications, such as in medical devices and equipment.

The LB-502MD is a versatile LED display module that can be used in many different types of applications. Its low voltage logic levels make it ideal for applications that require a reliable and cost-effective solution. Its wide range of display options and adjustable brightness and contrast make it suitable for a variety of applications in the industrial, automotive and medical fields.
