EA DOGM128S-6 application field and working principle

Introduction

EA DOGM128S-6 is a monochrome graphic LCD module with 128x64 pixel. It features an STN display from 5 to 6.7V voltage system and advanced viewing angle. Its wide temperature range from -20 to +70°C, long operating life from 50K to 100K hours, self-illuminating backlight and platform independent command set make it an ideal choice for a variety of industrial application fields. It is widely used in industrial, medical equipment, digital meter, STN LCD display and many other displays.

Application fields

1. Automotive: This display is ideal for making automotive dashboards, displays and instruments. The backlight and wide-angle viewing make it particularly useful in harsh environments. It is also used in remote controls and wireless car alarms, parking sensors and other automotive safety systems.

2. Industrial: Its long life, wide temperature and moisture range, high contrast and low power consumption make this display ideal for industrial applications. It is commonly used in sophisticated industrial equipment, such as process control, metering, alarm systems and factory automation.

3. Medical: The EA DOGM128S-6 is an ideal component for medical equipment due to its small size, low power consumption, self-illuminating backlight and wide viewing angle.

4. Digital meters: This LCD module can be used in a variety of digital meters, such as gas meters and water meters.

5. Consumer and home automation: As a self-illuminating display, it is ideal for home automation and consumer applications, such as smart thermostats and home appliances.

Working principle

The EA DOGM128S-6 is a modified version of the standard STN LCD. It uses a framed display, with a 8x12 grid of pixels that can be controlled independently. Each pixel emits light when the corresponding segmented FET is turned ON. The frame rate for this module is around 100Hz, which means that each frame is updated at a rate of 100Hz. In order to be able to switch from one frame to another, the controller must be updated with new values at least every 10ms (1/100).

The module is powered by a single 5 to 6.7V voltage supply which can be provided by a battery or any other source. In order to turn ON a certain LED of the module, the CPU has to issue the command to the LCD controller IC. This command is interpreted and then the appropriate circuitry is switched ON. The external power source is then used to display the corresponding image.

Conclusion

The EA DOGM128S-6 is a versatile display module that can be used in a wide variety of applications, from automotive to industrial, from medical to consumer. Its single-voltage 5 to 6.7V power supply gives it extra flexibility. Its long life, wide viewing angle and easy frame refreshing make it an ideal choice for many applications.
