EA DOGM128B-6 Application Field and Working Principle

The EA DOGM128B-6 is an LCD module belonging to the DOG display series. It is a graphic display module with a resolution of 132x64 pixels, blue blacklight and a controller ST7565R. DOG displays are normally used for a range of applications requiring the display of simple information or small amounts of data, from instrument panels or text-based systems to signal monitoring or digital gauges.

It is designed with a wide operating temperature range of -20 ℃ to +70 ℃. The controller also allows for a wide range of interface options, including 8-bit and 4-bit microprocessor (MPU) interfacing as well as serial I2C and SPI interfaces.

The EA DOGM128B-6 works by powering its backlight first, then transferring graphical data from a microcontroller to its controller, the ST7565R. This LCD module requires the serial interface to transmit to the controller, then the controller converts the serial data into parallel data so the LCD can display it. In order for the transistors in the LCD to turn on and off in the proper ways, the ST7565R needs to use an SIR (source-in-level) or an SED (source-enabled-level) voltage. The SIR voltage is set when the transistor is positive, while the SED voltage is set to the negative.

The ST7565R is also able to adjust the contrast between the backlight and the LCD pixels. The user can adjust the contrast in order to maximize the clarity of the information displayed. The ST7565R can also invert the logic levels of the display, allowing the user to invert the image being displayed on the LCD.

The EA DOGM128B-6 is available in two different versions: one which is compatible with four-bit MPU interfacing, while the other is compatible with eight-bit MPUs. It has a wide range of applications, such as instrument clusters, instrument panels, game consoles, medical instruments and smart home control systems.

The EA DOGM128B-6 offers the user a reliable, low-cost LCD module with a wide range of features and functions for a variety of applications. It is a perfect choice for any display needs, including basic text or small amounts of data. The ST7565R controller provides a reliable interface for the LCD and several advanced features for easier development and integration of the EA DOGM128B-6 display module into any project or design.
