LTD-6730P

LTD-6730P application field and working principle

The LTD-6730P is a kind of 10 x36 dot matrix LCD module which is a segment type character and numeric display module. It mainly consists of the LCD drive IC and controller IC, a built-in power circuit, and a FPC drive unit (FPC) with a lamp.

As one of the most commonly used LED character and numeric display modules, the LTD-6730P has a wide range of applications in industrial control equipment due to its simple structure, low power consumption, long control distance, and low cost.

Application

The product is mainly used in office automation equipment, medical equipment, automobile in-car audio equipment, home appliance product control and other embedded digital display systems.

• Industrial control equipment, such as numerical control equipment, process control systems and machine tools.
• The communication equipment, such as optical communication power meters.
• The instrumentation, such as the automotive tester, aviation tester and environment tester.
• The medical equipment, such as clinical analysis instrument, color Doppler ultrasound imaging system and various medical instrument.
• The entertainment equipment, such as the model aircraft, music equipment and so on.

Working principle

The working principle of this display module is to convert the digital signals into analog signals through the on-board logic cells, and then convert the analog signals into corresponding displacements on the display. The displacement signals of the display are modulated by the LCD drive IC and the controller IC, and then output to an LCD display with a built-in power circuit. In addition to the same transistors and capacitors that form the power section, the power section also includes a battery, current setting resistor and FPC terminal.

The FPC unit transmits the power and signal voltage to the LCD. FPC is a high performance, low cost and low signal transmission interference of the connecting component, it has a wide range of applications in high-precision instrument and communication equipment, etc. therefore, with the help of FPC drive, the LTD-6730P not only can be easily adapted to the highly reliable system, but also match its high performance, low cost and low power consumption.

Summary

The LTD-6730P LED character and numeric display module is made up of an LCD drive IC and controller IC, a power circuit, and an FPC drive unit. It is widely used in various fields such as industrial control equipment, communication equipment, medical equipment and entertainment equipment. The working principle of this display module is to convert the digital signals into analog signals and then modulate these analog signals with the LCD driver and controller ICs, and output them to the LCD display with the help of the power circuit. Moreover, the FPC drive unit further improves the overall performance, cost and power consumption.
