INND-SS40RAG application field and working principle

Introduction

INND L.E.D. displays (L.E.D. = Light Emitting Diode) are a type of display that are used to show alphanumeric characters, symbols, and text. They are composed of an array of small light elements that are individually addressed and controlled, allowing for the display of one or more characters, numerals, and/or symbols. The INND-SS40RAG series are character modules which feature 4x8 dots, allowing the user to display up to 8 characters.

Application Field

This particular 4x8 dot matrix display is widely used in digital devices to display numbers, symbols, or other information. It is popular in digital watches, industrial meters, digital clocks and LED signs. The module is also widely used as a part of various communication systems, such as GSM/GPRS systems and other signaling systems where visual identification and status feedback is required.

Working Principle

The operation of the INND-SS40RAG is based on the use of several components, including LEDs, shift registers, circuits for controlling the current, timing control, and address decoding. The LEDs are arranged in a 4x8 array, with each LED in the array connected to the shift registers. When the shift registers receive a signal from the address decoding circuit, they will activate the LEDs in the array in order to create the desired character or image. The address decoding circuit will read the signal from the control circuit, which determines which LEDs should be activated in order to display the desired character or image. The shift registers can also control the timing of the display, allowing for the animation of characters or images. The timing of the display is controlled by the control circuit, which determines how quickly the images should be displayed.

Conclusion

The INND-SS40RAG is a 4x8 dot matrix module that is used to display text and symbols. It is widely used in digital devices such as digital watches, industrial meters, digital clocks, LED signs, and GSM/GPRS systems. The module works by activating LEDs in the 4x8 array, controlled by shift registers and the address decoding circuit. The module can also be used to create animations by controlling the timing of the display with the control circuit.
