HDSP-H3E1 is an LED display that falls into the category of Display Modules- LED Character and Numeric. It is a 15-character, predefined common anode display module that can be used in a range of applications, including panel mount or card mount in home appliances, industrial controls, test systems and measurement instruments.HDSP-H3E1 typically comes with a 5x7 dot matrix for each character and has an array of common cathode pins for connection. The HDSP-H3E1 is available in several colors, such as green, red and yellow.HDSP-H3E1 has a wide viewing angle of up to 145 degrees, which improves clarity and visibility of the characters. It has a high contrast ratio which ensures the characters are more visible and legible. The HDSP-H3E1 also has an operating temperature of -40 ˚C to 70 ˚C, meaning it’s suitable for both indoor and outdoor applications.The HDSP-H3E1 has three major working principles: voltage stabilising, current-limiting and frequency-shifting. The voltage stabilising principle means the module’s constant-voltage LED driver can stabilize the driving voltage to eliminate the influence of temperature and driving current on the LED’s luminous intensity. This stabilizes the brightness and provides uniform illumination.The current-limiting principle sets a maximum current to protect both the load and display panel. This current-limiting principle is achieved by the constant current circuit built into the module’s LED driver. This circuit sets a limit to the maximum current driven, cutting it off as soon as a set current is reached.The frequency-shifting principle allows the LED’s heat to dissipate more quickly and evenly by setting the LED’s shifting frequency in a range from 300Hz to 25kHz. This helps to reduce the power consumption and ensure the longevity of the display module.These three working principles make the HDSP-H3E1 suitable for different application fields. This includes commercial display, communication and instrumentation industry, medical equipment, home automation and audio-visual equipment.The HDSP-H3E1 can also be used in interactive displays such as kiosks or information points, providing a way for users to access information or carry out transactions.The HDSP-H3E1 is capable of controlling multiple LEDs simultaneously and incorporates an optical filter to obtain vivid images, with no bleeding over the coloured or dark backgrounds, making it ideal for logo displays and professional signage.It is also suitable for moving message displays in vehicular, ship and train applications. The HDSP-H3E1 is able to handle fast-changing messages and provides high visibility in sunlight, ideal for public transportation and outdoor public environments.All in all, the HDSP-H3E1 is a popular choice for a range of applications, due to its advanced working principles, wide viewing angle and high contrast ratio. It is a reliable, efficient and cost-effective choice when it comes to LED display modules.
