ACPSA04-41SURKWA

The ACPSA04-41SURKWA are LED character and numeric displays, which are self-illuminating LED displays. LED stands for light emitting diode, which is a combination of semiconductor materials that emit a narrow band of light when they are electrically stimulated. This makes them useful for a variety of applications where a bright, visible indication is needed, such as gauges, warning lights, and other forms of digital display. This type of display is common in many home electronics, such as electronic clocks and digital thermometers. In this article, we will discuss the application field and working principle of the ACPSA04-41SURKWA.

Applications

The ACPSA04-41SURKWA LED character and numeric displays are ideal for use in a variety of industrial and commercial applications, such as automotive dashboards, medical equipment, household appliances, and public transportation vehicles. In addition, these displays are especially suited for low-power requirements, as well as for applications where brightness is essential for effective visibility. These displays are also resistant to shock, vibration, and other external disturbances, making them a great choice for harsh environments.

Working Principle

The working principle of the ACPSA04-41SURKWA is based on the electro-optical properties of semi-conductors. When the display is turned on, a positive voltage applied to the anode side of the display causes current to flow in the diode segment. This current causes electrons to be released from the electron trap layer within the diode, causing the PN-junction to become forward biased. The electrons are then recombined in the PN-junction to form holes that then recombine with the hole-trap layer, emitting photon energy in the form of visible light to illuminate the display. When the display is turned off, the voltage is reduced and the electrons are prevented from recombining with the hole-trap layer, terminating the photon emission and turning off the display.

Conclusion

In conclusion, the ACPSA04-41SURKWA are LED character and numeric displays that are suited for a variety of applications due to their low-power requirements and high resistance to external disturbances. The displays work on the principle of electro-optical properties of semiconductors, which use an applied voltage to cause current to flow in the diode segment, emitting photons that create a visible light.
