The module is designed for use in industrial and commercial applications, including alarm displays, time and temperature displays and other types of information displays. This article will discuss the application field and working principle of the SA05-11GWA, and provide a brief overview of its features.

Application Field

The SA05-11GWA is suitable for use in industrial control systems, communication and entertainment systems, as well as medical and educational systems. It is well suited for applications that require a high degree of reliability and durability, such as in security systems and monitoring equipment. This display module can be used in a wide range of applications and is reliable enough to provide accurate and timely information displays.

The SA05-11GWA is capable of displaying numbers, symbols and graphic symbols, including user-defined symbols. It has an extended operating temperature range and is insensitive to vibrations, ensuring reliable operation in harsh environments. Additionally, the module has a very low power consumption, making it ideal for battery-powered applications.

Working Principle

The SA05-11GWA uses LED technology to emit light from its multi-segmented dot matrix display. A number of LEDs are positioned on an etched circuit board and are each connected to micro-controllers which control the operation of the display. The micro-controllers are programmed with the firmware which allows them to interpret the data sent to them and display it on the dot matrix display.

When the SA05-11GWA receives data, the micro-controllers interpret the data and direct the LEDs to illuminate the appropriate segments of the digit or character. This process is known as pixel mapping, and it is used to create the graphical display. The SA05-11GWA can also control the brightness of the display and the speed of the display by varying the duty cycle of the pulse width modulation.

Features

The SA05-11GWA has several features that make it suitable for use in a variety of applications. It comes with a built-in voltage converter with an adjustable output voltage range that can be used to power other modules and peripherals. The module is equipped with an anti-page refreshing function, which reduces the flickering of certain segments of the display when receiving new data. It also comes with an anti-static function which eliminates the effects of static electric charges.

In addition, the SA05-11GWA has built-in protection circuits that protect against over-voltage and reverse voltage. The module has a built-in temperature sensor which helps reduce the brightness of the screen when it gets too hot, ensuring a longer life of the LEDs. Finally, the module has a built-in self-test feature which allows it to identify any malfunctioning LED and notifies the user if it needs to be replaced.

The SA05-11GWA is a versatile LED character and numeric display module suitable for a wide range of industrial and commercial applications. Its extended operating temperature range, low power consumption and various protection circuits make it ideal for harsh environments. Additionally, its pixel mapping capabilities and anti-page refresh features ensure that data is displayed accurately and reliably.
