LN514YA is a 14-segment display module that can be used as a character shown module with multi-level brightness. It uses a standard arrangement of bright red and green LEDs arranged in an array of 14 segments. With the addition of four special functional characters, the display is more vivid and clear.

Application field of LN514YA

LN514YA is used in projects of various scales. From industrial production information display and warning signs to simple home projects and data indicators, LN514YA is widely used. Moreover, LN514YA is well adapted to withstand harsh environments, making it an ideal choice for outdoor displays in areas like airports and other public spaces. The field angle is wide, so that it can be used in a variety of scenarios.

Working principle of LN514YA

At the core of LN514YA is an array of bright red and green LEDs arranged into segments, which displays a character. The segments of the LED module is controlled by chips, and each chip can control one or more LED segments. In addition, there are constant current drivers and decoders to convert digital signals into analog signals.

In order to display characters, the LED module needs to send data signals to indicate whether the LED segments should be arranged to form the given characters. The chips are arranged in 8×8 blocks to store bit values. A total of 8 bits can form an 8-digit code, representing 256 states of the character. When the corresponding bit values are sent to the chips, the character display is realized.

In addition, the LN514YA display module has a wide operating temperature range, which can be used stably in temperatures ranging from -40°C to +85°C. It has a unique low power consumption design which makes it energy efficient.

Conclusion

LN514YA is a versatile display module suitable for a wide range of applications, from industrial production information displays to domestic applications. It is well suited for outdoor displays due to its wide field angle and wide temperature range. The working principle of the display module is based on an array of red and green LED segments, which are controlled by chips and constant current drivers. The design of the display is optimized to ensure low power consumption and long lifetime.
