LED character and numeric displays offer lighting solutions for many applications. In particular, the LDD-A513RI model is a controller-driven 7-segment LED digital display designed to display numerical and alphanumeric characters. This display is widely used in automotive, medical, aviation, and navigation systems and is suitable for harsh environments.

The LDD-A513RI is a compact, light weight, and easy to install LED digital display with a maximum power dissipation of 0.30 watts which is relatively low compared to other LED digital displays. The luminous intensity is 200-800 mcd per segment and its design allows for a high level of light output. It operates with a typical full angle viewing of 120 degrees. The display can be switched on or off with a DC power supply. It is also capable of displaying multiple characters by combining multiple segments.

The LDD-A513RI has a controller-powered on/off function with a PWM signal. The PWM signal can be programmed to enable a variety of dimming effects. Hardware timers are provided to manually cycle through the lighting on/off. It also features switchable lengths for reset or store operations. Externally accessible memory locations are provided to enable different functions, such as character select, for easy access and fast data entry.

To control the LDD-A513RI, a master control unit is required. This will be connected to the display via a 3-wire serial communication interface. The master control unit can be programmed with a variety of information, such as character selection, brightness, special effects, and display direction. Once programmed, the master control unit will send a signal to the display allowing it to show the selected message or character.

The LDD-A513RI is based on liquid crystal technology and has many advantages over traditional LCD digital displays. It has a higher brightness, a longer life span, and is more resistant to shock and vibration. Additionally, it does not require an external light source, as the light for each character is created by the display itself. This makes it easier to install and maintain in comparison to LCD displays.

Overall, the LDD-A513RI is an excellent LED character and numeric display. Its features provide a lighting solution for many electronic applications. Its durability, reliable performance, and easy installation make it an ideal choice for those looking for a high-quality display with maximum performance in the harshest environments.
