The LTC-2621JD is a display module from the LED Character and Numeric category. It is a 20-character by 4 lines 7-segment LCD display that supports both SIP and DIP package type. It provides an easy way to quickly add LCD display into various applications.

The LTC-2621JD belongs to the family of alphanumeric LCD (Liquid Crystal Display) displays developed in order to meet the need for portability and low power consumption. These displays are ideal for applications where space and power is of high importance. As a result, they are widely used in industrial applications, computer and self-service kiosks, automotive, appliance, and other embedded projects that require LCD displays.

The LTC-2621JD is specifically designed to provide reliable and flexible display and control features. It features auto-bias and grade four backlight. Auto-bias offers a fully automatic display that starts up even with low voltages and is always bright in all conditions. Grade four backlight provides wider viewing angles and fewer blind spots than previously designed LCDs.

The LTC-2621JD is easy to interface and control using its two-wire (I2 C) and four-bit (SPI) interface. It is powered by a 3V-30V external power supply and has two built-in LED backlight drivers to control brightness. This module operates at temperatures between 0°C to 60°C.

The working principle of the LTC-2621JD is based on the electro-optical effect. It uses an array of liquid crystals suspended in a liquid between two conducting transparent electrodes, with a permanent electric field applied to the liquid crystals. The light is allowed by the crystals, which are held in an orderly orientation between the electrodes when an electric field is applied due to the voltage placed on them. Thus, each segment or character cut out from the LCD glass is activated when a current is drawn from that particular segment or character. As a result, this will display the desired character or number on the LCD.

In conclusion, the LTC-2621JD is a display module with an easy-to-interface and control working principle as well as a range of display and benefits. It is well-suited for a variety of applications where low power consumption and portability is highly desirable.
