Display Modules - LED Dot Matrix and Cluster.

HDSP2114S is a series of seven-segment LED devices which can be used to replace standard 7-segment numeric displays. It consists of a single, common cathode 7-segment LED display, designed with a black face and white segments. This series of devices is ideal for numeric displays or simple arithmetical computations.

Applications

The advantages of using these devices in electronic systems include their physical size, light weight and average service life. The segment displays are also easily programmable and allow for display changes quickly and reliably. The HDSP2114S is commonly used in consumer electronics, automotive electronics and industrial applications, such as scientific instrumentation, timers, counters and data processing systems.

Working Principle

The HDSP2114S is an integrated device with all the required components built into a single package. This includes LED driver circuits, LED display, 7-segment LED display and LED segments. The LED segments are connected in a linear configuration, with each segment connected to a common cathode. When the device is energized current flows through the LED segments and the LED display is illuminated.

The LED segments are controlled by an individual resistor, which can be adjusted to selectively turn on or off the LED segments. When the resistor is adjusted, the current through the LED segment will increase or decrease. This adjustment achieves the desired pattern on the display. The LED segment is also connected to a voltage source, whose voltage will determine the brightness of the LED.

The HDSP2114S is designed such that the cathode voltage and segment voltage are independent from each other. This allows for the current through the segment to remain constant with varying voltage. This reduces the power dissipation in the device and extends the life of the LED display.

The HDSP2114S is designed for applications where space is a constraint. It provides a compact, low-cost 7-segment LED display and can also be used as a dot matrix display if required. It is ideal for applications where a display has to be fabricated with a single package and can easily be used in combination with other LED displays.

Overall, the HDSP2114S series of LED devices is an economical option for displaying both numeric and alphabetical characters in an array of applications. It is a compact, low-cost package and can easily be incorporated into a wide variety of electronic systems. The segment displays are easy to program and can be used as single or multiple displays. The adjustable resistor allows for precise control over the individual LED segments and provides a reliable, cost-effective way to display any desired information.
