VAOS-A402S9-BW/50 Application Field and Working Principle

VAOS-A402S9-BW/50 is an LED Dot Matrix Display Module developed by VAOS. It is a compact, lightweight and energy-efficient LED matrix display module. It is designed for applications that require high brightness, good contrast and long-term reliability. It is powered by two AA batteries and is ideal for both commercial and home use.

Application Field of VAOS-A402S9-BW/50

VAOS-A402S9-BW/50 is suitable for industrial applications such as automotive, instrumentation, computer, process control, audio/visual display and medical systems. It is also ideal for outdoor applications due to its resistance to environmental influences such as moisture, dust, corrosion, shock and vibration. It has excellent luminous efficiency, providing bright and clear images from a short viewing distance. Applications include but are not limited to commercial signs, safety alarms and warning lights.

Working Principle of VAOS-A402S9-BW/50

VAOS-A402S9-BW/50 is a dot matrix module that consists of a dot matrix array with columns and rows of LEDs. It uses a controller with 8-bit multiplexing (MUX) and active refresh to refresh the display every so many milliseconds. The controller scans each row and column to determine what LEDs should be illuminated. The data is then sent to the driving circuit which drives the LEDs on or off as instructed. The module can display text, numbers and other characters in both digital and analog formats.

VAOS-A402S9-BW/50 has an additional feature called Contrast Control (CC). This feature allows for the brightness and contrast of the display to be adjusted by a 6-bit signal. The CC also ensures that the levels of brightness and contrast remain constant even when the display is viewed from different angles. It is a very useful feature in applications that require a bright and consistent display in any lighting condition.

The module is further enhanced with an auto-response time control (ARTC) feature. This feature measures the time it takes for the display to reach peak luminance and then adjusts the voltage accordingly. This ensures that the display stays bright and clear even when the power supply voltage varies. This is particularly useful in applications that run on battery power.

VAOS-A402S9-BW/50 is an LED Dot Matrix Display Module designed to provide bright, clear and consistent images with excellent image quality in challenging applications. Its wide range of features and good power efficiency make it an excellent choice for industrial and outdoor applications.
