The DSM7TA39106T is among the newer display modules capable of displaying both LED character and numeric information. This device is a popular choice for digital signage and other applications requiring the use of LED characters. In this article, we will discuss the application field and working principle of the DSM7TA39106T.

Application Field

The DSM7TA39106T is ideally suited for applications requiring the use of both character and numeric display. This device makes it easy to display both alphanumeric and numeric data in order to provide the necessary information to the user. The DSM7TA39106T is commonly used in digital signage applications such as signs, billboards, and kiosks for the display of time and date information, menu selections, service information, etc. The device is also used for gaming machines and in traffic control systems.

Working Principle

The DSM7TA39106T is a direct view device that requires no external power supply as it is powered by the backlight. The device includes a total of four control lines: one enable control (EN), three data control lines (data), and one 100Hz clock (CLK). It utilizes an efficient message format that is composed of both ASCII and 5x7 dot matrix characters. The display module is designed with both 1/4 character and 1/8 character dots, allowing for the display of both binary and numeric data.

The DSM7TA39106T is a multiplexed LED character display device. Multiplexing reduces the number of lines used to control the display module by scaling down the characters row-by-row. In addition, the device features a built-in 5V boost circuit and negative voltage generator, making it suitable for both 3.3V and 5V supplies. The built-in boost circuit also allows the device to work under high temperature conditions.

Conclusion

The DSM7TA39106T is a versatile LED character and numeric display module that is suitable for applications requiring both alphanumeric and numeric data. It utilizes an efficient message format composed of both ASCII and 5x7 dot matrix characters. The device is powered by the backlight, and includes a 5V boost circuit and negative voltage generator. With its multiplexing feature, the DSM7TA39106T is a reliable, energy efficient display module for digital signage and other applications requiring the use of LED characters.
