SA39-11GWA is an LED character and numeric display module designed for various indoor applications. It is a 7-segment module with a two-digit display, best suited for displaying numbers and characters in dark environments. It utilizes a red LED display for easy viewing in any indoor setting.

The SA39-11GWA module features a 7-segment display and a 3.2” inch size. Its wide viewing angle (178° minimum) makes the module ideal for displaying characters and numbers without the need for backlighting or reflection. It also has a low power consumption of 80mA per segment and a tight frame construction to ensure stable viewing and accurate display.

The SA39-11GWA module also features a low static power consumption of only 100uW and a refresh rate of 7ms for a dimming range of 0-100%. It also has a wide supply voltage range of 6V to 24V DC with a maximum operating current of 250mA. Moreover, its clear UV elastic self-adhesive kit allows for easy installation on any display unit.

As for its working principle, the SA39-11GWA is driven by TTL/CMOS level control inputs and suitable for multiplex control. The Red LED display elements have common anode connections and can be addressed in columns and rows. The module utilizes the multiplexing technique to maximize the available brightness by transferring the light into the higher intensity angle ranges of visibility. In this technique, the intensity of the LEDs is varied in time intervals, approximately a few milliseconds, which will appear brighter to the eyes than what is actually lit. This allows it to provide a sharper display and brighter viewing angles.

In conclusion, SA39-11GWA is an ideal LED display module for indoor applications. It offers a wide viewing angle and low power consumption for a more efficient viewing experience. Additionally, the easy installation, refresh rate, wide voltage range and TTL/CMOS level control make the SA39-11GWA a versatile and reliable option for displaying numbers and characters in dark environments.
