DLO4135A application field and working principle

The DLO4135A is a dot matrix LED and cluster display commonly used in various types of displays. It is characterized by relatively low power consumption as well as a high brightness level, making it an excellent choice for applications requiring a small footprint and low power consumption such as scoreboard, automotive and portable devices.

DLO4135A has the characteristics of good fireproof, waterproof and dustproof, which makes it suitable for outdoor display applications. It can be used in information displays, such as street name signs, navigation systems, direction indicator systems, countdown time, ticket dispensers and fare indicators.

The structure of the DLO4135A display unit consists of eight small 1"x1" dot matrix modules, forming a 8x80 pattern that can be configured in a variety of output formats, such as 5x16, 8x16, 5x24 and 12x40. Each module has four built-in LEDs, which can be activated in any order, allowing a wide range of applications.

On the working principle of DLO4135A, it has two modes of operation, AC drive and DC drive. In AC drive mode, the module receives an electric current, allowing the LEDs to be lit at the same time. In the DC drive mode, each LED can be lit independently.

The current of the LED will gradually increase and reach the peak illumination voltage, then gradually drop and finally cut off, which needs to be done through voltage or current limitations. The display unit is also equipped with a unique, self-locking mechanism, which prevents unacceptable flickering when turning on, off or changing the brightness level. Furthermore, the module offers a wide range of supported brightness levels, and users can set their desired brightness level.

In conclusion, the DLO4135A display module is an excellent choice for various applications due to its small footprint, low power consumption, high brightness level and compatibility with various operating modes. It is a perfect solution for use in scoreboards, automotive and portable devices, as well as in various information displays.
