ACSA04-41PBWA/A-F01 is a display module with 4×7 segments, used in applications that need a visual display. It is designed to suit many different applications including timers, meters and counters, providing fast and easy implementation through its high readability and wide viewing angle design.

This display module features a low drive voltage level of 0.4 to 0.9V, low current consumption of max 5mA, and a wide viewing angle of ≥60°. The overall dimensions of it are 59.2 x 25.2 x 8.1mm, making it an ideal choice for applications with limited space.

This display module has a 4×7 segment LED alpha-numerical characters display divided into two parts, with the first part containing 4×4 LED’s for numerical display and the second part with 4x3 LED’s for alphanumeric display.

The ACSA04-41PBWA/A-F01 is designed to provide reliability in harsh operating environments and its blue color LED features better visibility than LCD. It has good anti-glare performance, low power consumption with high brightness, and wide viewing angle.

The display module is made up of a top and bottom PCB which is separated by a ground mid plane. The top PCB houses the LED segments, the LED anode (positive terminal) and the LED cathode (negative terminal), while the bottom PCB houses the LED driver and power resistor. The LED driver IC controls the LED segments and the power resistor sets the current through the LED segments and sets the voltage level of each LED in the segment.

The driver IC for this display module is the AP2920L3 which can control up to four digital LEDs, allowing for higher levels of integration. This display module only needs one power supply for the drive IC, reducing the number of components used in the design.

The working principle of this display module requires the 4×7 segment characters display to be powered and the LEDs to be connected to the positive and negative terminals. The driver IC is responsible for controlling the flow of current through the LED segments and setting the voltage level of each LED. Once the current flow and voltage levels have been set, the LEDs will light up and display the desired information.

In conclusion, the ACSA04-41PBWA/A-F01 is a display module designed specifically for applications that need a visual display. It features a 4×7 segment LED alpha-numerical characters display which can be divided into two separate parts, with the first four LEDs in the segment designated for numerical display while the second four LEDs in the segment designated for alphanumeric display. This display module also requires one power supply for the driver IC, reducing the component count and complexity in the design. The driver IC is responsible for controlling the flow of current through the LEDs and setting the voltage levels for each LED, allowing for the display of the desired information.
