2947

Introduction

A 2947 LED Dot Matrix and Cluster Display Module is a segmented display device designed for applications such as motors, car and tractor displays and meters. It uses 9 series colored LED\'s to form a 9-segment indicator with two separate bars. Each dot can be controlled independently in various directions. The display is bright and easy to read. The module is composed of two separate flat cases that connect together. This design allows it to be used in environments covered by covers, such as in vehicle and instrument clusters.

Application Field

2947 LED Dot Matrix and Cluster Display Modules are used in a variety of applications, including automotive, electronics, and medical devices. Automotive applications include instrument clusters, such as on dashboards, in instrument panels and in displays on car components such as door handles. Electronic devices such as calculators, video games, and cell phones use a 2947 LED Dot Matrix and Cluster Display Module to display numbers and letters. Medical devices may use the 2947 module for test data display.

Working Principle

The 2947 LED Dot Matrix and Cluster Display Module operates on the principle of differential series control. Each dot of the module requires two separate inputs. The first input will be a positive DC voltage from a common power supply, while the second input is a control voltage from the host device. Each dot is internally connected to a series combination of the two voltages, allowing it to be driven individually in either forward or reverse direction. This is accomplished by controlling the polarity of the control voltage.

Advantages

The 2947 LED Dot Matrix and Cluster Display Module has several advantages over other similar devices. It is more efficient than other devices, as it requires a lower input current and voltage. This reduces the overall cost of the power supply by up to 50%. As it is a segmented display, it can be used to display numbers, characters and symbols with ease. The brightness of the display can be adjusted to suit the application, from very low to very high.

Conclusion

The 2947 LED Dot Matrix and Cluster Display Module is a segmented LED display device which is suitable for a variety of applications. Its efficient power consumption and adjustable brightness make it an ideal choice for a wide range of applications, including automotive instrument clusters, portable electronics, and medical devices. It is also relatively inexpensive, making it an attractive choice for many users.
