Introduction
HCMS-3906 is a standard LED dot matrix/cluster display module developed by Holtek. It is widely used in short message display, instrumentation and control systems, etc. This article will discuss the application field and working principle of the HCMS-3906.
Application field
• The HCMS-3906 is mainly used in short message displays, such as traffic sign displays, security alarm systems and digital electronic clocks. It can also be used as timer and alarm indicators.
• The module is well-suited for instrumentation and control systems, like level indicators, out-of-range and error alarms, autoclave temperature displays and so on.
• HCMS-3906 can be used in many other applications, such as high temperature reading displays, water flow rate indicators, acoustic meters and so on.
Working principle
The HCMS-3906 is composed of two parts: a display driver IC and an LED dot matrix/cluster. The driver IC generates the drive signals for the LEDs according to the inputs. The dot matrix consists of a number of LEDs arranged in an X-Y matrix. The X-Y matrix is connected to the driver IC, which controls the lighting of the individual LEDs.The driver IC can be programmed to control different types of display. It has two control pins—D-out and RST—for controlling the changing patterns of LEDs. The D-out pin is used to select different display types, while the RST pin is used to reset the display.The HCMS-3906 has an internal oscillator that generates the clock signals to drive the LEDs. It has an internal circuit for detecting the temperature of the module. This enables the module to automatically adjust its drive signals according to the temperature.The HCMS-3906 also has a wide range of other features, such as brightness control, scan control, row and column select control, etc. These features enable the module to be used in a variety of applications.
Conclusion
The HCMS-3906 LED dot matrix/cluster display module is widely used in short message displays, instrumentation and control systems and other applications. It is composed of a display driver IC and an LED dot matrix/cluster. The driver IC generates the drive signals for the LEDs according to the inputs, and the dot matrix is connected to the driver IC. The driver IC provides various control pins to control different types of display. In addition, the HCMS-3906 has an internal oscillator, temperature sensing circuit and other features that enable it to be used in a variety of applications.
