HDSP-5501, a standard size LED character display with 7.62mm character height, is designed for military, industrial and business applications. The HDSP-5501 is a type of Display Modules - LED Character and Numeric, which has a total display height of 23.1 mm. The display consists of six digits, and each is composed of 14 Segment Assemblies (SSA), features 8 red LEDs surrounded by a black mask, high brightness and three-digit discharge cathode. The HDSP-5501 has a wide viewing angle of ±20° and utilizes light emitting diode technology which ensures an excellent display quality.

The working principle of HDSP-5501 is based on the fact that semiconductor devices consist of a P-N junction. When voltage is applied across the semiconductor material, the current flow through the material varies inversely with the increase in the temperature. Thus, by varying the temperature through the application of current, the current flow through the material can be adjusted dynamically to achieve the desired display. The display controller generates signals to drive the LED segments based on these current adjustments, which will cause LED segments of the display to illuminate. The LED segments are controlled by a series of enable lines, which functions as an on/off switch for the LED. The enable lines can either turn on or off the LED segment; this allows the LED segment to be either completely lit or completely off.

The four digit code of a HDSP-5501 consists of a single digit and three times four digits, which is controlled by a single enable line. To ensure that the entire display is lit uniformly, each LED segment must be enabled individually. To do this, four enable lines are used, one for each digit. The four digit code can also be programmed to decimal/hexadecimal modes and can be made to show exact digital combinations.

Overall, HDSP-5501 is a highly efficient and cost-effective type of Display Modules - LED Character and Numeric. It has great advantages such as high brightness, wide viewing angle, and small size. By using light emitting diode technology, the display can produce a very clear and bright display, making HDSP-5501 a perfect choice for many applications.
