OK204-25-OR Application Field and Working Principle

Introduction

The OK204-25-OR is a type of LCD display module, which has a two-line character and numeric display. It is designed with a wide viewing angle, comprehensive display functions, and low power consumption. Additionally, this module can be seen under a variety of lighting conditions for industrial, automation, and process control applications.

Application Field

The OK204-25-OR is widely used in a range of industrial, automation, and process control applications. This module can be integrated into a variety of systems for viewing and analyzing real-time data such as counter, temperature, pressure, flow, and level. It is also useful for displaying parameters of various machine tools, such as tachometer, speed, and timing.

In addition, this module is also applied in analyzing and monitoring applications such as home automation, automated manufacturing systems, and medical center systems. This display module can provide high accuracy and reliable data under extreme working environments such as high voltage and temperature.

Working Principle

The working principle of the OK204-25-OR is based on liquid crystal display (LCD) technology. This is a type of flat panel display which uses liquid crystals as its main component. Liquid crystals work by making use of electrical charges to align an electrical field, which causes polarized light to rotate inversely. The degree of rotation is then used to determine the lightness or darkness of the display.

This module has integrated LCD components, including the liquid crystal layer, a mask for controlling the orientation of liquid crystal molecules, and a pair of polarizing filters. The filters are placed in front of each other and are oriented at an angle which is perpendicular to each other.

When an electric current passes through the liquid crystal layer, the liquid crystal molecules will align and rotate the electric field. This causes polarized light to rotate and the display to become visible. By adjusting the electric field, different shades of lightness or darkness can be seen.

Finally, the interface of the OK204-25-OR includes RS232 or I2C for communicating with the microcontroller. It is also capable of driving external LEDs for programming, verifying, or debugging purposes.

Conclusion

The OK204-25-OR is a type of LCD display module which is used for industrial, automation, and process control applications. It has a two-line character and numeric display and can be seen under a variety of lighting conditions. The working principle of this module is based on liquid crystal display technology and its interface includes RS232 and I2C. Ultimately, the OK204-25-OR is a reliable and accurate LCD display module which can be used in a wide range of applications.
