Utilizes FSTN (Fringe Stacked Thin Film Compensation Vertical Alignment) forward display mode. Some models also support DFSTN (Double Film Stacked Thin Film Compensation) technology, combined with fully transparent polarizing film. The backlight can pass through completely, ensuring clear display effects in both bright and dark environments, with high contrast for characters and graphics.
Utilizes COG (Chip on Glass) technology, directly bonding the driving chip onto the glass substrate, eliminating the need for traditional PCB boards and connection components, achieving ultra-thinness of the module. For example, the 2.4-inch model has an external size of only 57.5x41.7x4.3mm, and the 2.8-inch model is only 74x48x5.4mm.
The working voltage is mostly 3.3V. The common driving chips are ST7567, ST7565R, etc. They support MCU interfaces. Some models are compatible with SPI. The electrostatic discharge (ESD) resistance reaches ESD 8KV. The operating temperature range is -20℃ to 70℃, suitable for complex environments.
Resolution is 128x64 dot matrix. The dot pitch varies from 0.41x0.37mm to 0.51x0.51mm depending on the model. Some products are equipped with red, green, and blue backlight or yellow-green backlight. The display content includes text, simple graphics, and icons.
- Instrumentation: Core display component for industrial multimeters, oscilloscopes, pressure gauges, etc., used to display measurement data, equipment status and operation menus.
- Portable medical equipment: Displays patients' physiological indicators in glucose meters, blood pressure monitors, and portable electrocardiogram machines. Its low power consumption and wide temperature range characteristics are suitable for medical stability requirements.
- Industrial control: On control panels of industrial automation equipment, presents operation parameters and alarm information. The high reliability of COG process adapts to complex industrial environments.
- Embedded systems: Compatible with controllers like Arduino and C8051, often used in human-computer interaction interfaces for small embedded projects such as smart home controllers and industrial control terminals.
