SLG2016 is a LED display module developed by Photon Detector Inc. It is a small LED dot matrix with 6 pins for power and data connection, plus a 3-pin cluster for easy wiring. It is designed for indoor and outdoor applications in a wide variety of scenarios. It is also ideal for use in limited space applications due to its small size.

The SLG2016 dot matrix display module consists of 6 individual LEDs per row with 3 columns. Each LED has its own current and voltage characteristics which are restricted by a 3 terminal resistor. The resistor determines the maximum power of the LED, allowing each LED to be operating at its safe level. The LED voltage stays constant while the LED current is adjusted to match the LED brightness levels.

The working principle of the SLG2016 is very simple. A microcontroller, such as an 8051, generates a pulse width modulated (PWM) signal, which is connected to the resistor of each LED. The PWM signal adjusts the impedance of the resistor, and therefore the current that flows through the LED. This current is then used to drive the LED backlight, causing the LED light to yield the desired brightness.

The SLG2016 can also be used in clusters for applications where multiple LEDs need to be used in a coordinated manner. Each cluster consists of 8 LEDs. By varying the PWM signal, the entire cluster of LEDs can be sent a single color or message at the same time. This allows for interesting and complex displays in a small space. This feature is particularly useful for applications such as advertising, traffic control, and counter displays. The PWM signal can also be arranged in such a way that the LEDs can be programmed to scroll text or images across their surfaces.

The SLG2016 is a powerful LED module for display applications. It is extremely small, which makes it ideal for limited space applications. Its 6 pin configuration and the added 3-pin cluster give it flexibility. The ability to coordinate multiple LEDs in a single cluster to yield complex displays makes it one of the most versatile small LED display modules on the market.
