DSM7TA28101T Application Field and Working PrincipleDSM7TA28101T is a Display Module from the LED Character and Numeric range of products. This module is designed for industrial, medical, and other applications. It is available in different colors and shapes and provides an easy to read numeric numeric display.The application field of this module covers the following different fields: Industrial, medical, office and home automated systems, vending machines, railway stations. The main feature of this display module is its ability to display up to 4 digits of numeric data in a two color format. It has two colors, Green and Blue, one for each digit. The digit height is 7 mm and the character size is 5x7 dots. Furthermore, the display also has a powerful backlighting system to provide higher visibility.The working principle of the DSM7TA28101T is as follows: The display module is based on the principle of direct view LEDs (Light-Emitting Diodes). These LEDs emit light which is used to display characters and numbers on the display.The module consists of four individual LED numerics, each composed of 28 LED elements. When current passes through each LED within the unit, it causes it to emit light, making the specific areas of the character visible. By controlling the current in each of the four LEDs, it is possible to display four different numbers. The current of each LED is controlled by the use of DC voltage. This voltage is controlled by the use of integrated circuit logic and is applied to each LED. The more current passed through the LED, the more intense the brightness.The backlighting system in the display module works by a combination of LED’s and incandescent lamps. LEDs are used to give an indirect light to the display module, while the incandescent lamps are used to directly illuminate the display.In summary, the DSM7TA28101T Display Module is an excellent choice for display applications in industrial, medical, office and home automated systems, vending machines, railway stations, and other applications. Its bright LEDs and backlighting system make it an ideal choice for any display application. Furthermore, its user-friendly design makes it easy to integrate into most systems.
