The JGS12864W3201-12864 Graphic LCD Screen, as a graphic dot matrix liquid crystal display, involves multiple aspects in its manufacturing process. Below is a detailed summary of its technology:

I. Display Technology

STN Display Technology: The 12864 monochrome screen uses STN (Super Twisted Nematic) display technology, which provides high contrast and viewing angle stability.

II. Structure and Materials

Liquid Crystal Cell: Composed of liquid crystal molecules sandwiched between two parallel electrode layers. The alignment of these molecules changes under an electric field, altering the direction of light propagation to achieve display.

Backlight System: Typically uses LEDs as the backlight source to provide stable illumination. Some models may employ side-mounted high-brightness white LEDs with lower power consumption.

III. Drive and Control

Drive Method: The 12864 monochrome screen supports various drive methods, such as 1/64 DUTY, 1/9 BIAS or 1/32 DUTY, 1/5 BIAS, which effectively control the screen display.

Controller: Common controllers include KS0108 or T6963C, which receive and process external data and commands to control the alignment of liquid crystal molecules for display.

Data Transmission: Data is typically transmitted via 8-bit parallel/6800 interface or serial interface to ensure efficient data transfer.

IV. Performance Parameters

Dot Matrix Format: 128x64, meaning the screen has 128 columns and 64 rows of pixels.

Dot Size and Dot Pitch: Dot size is 0.39x0.55mm, dot pitch is 0.44x0.60mm, which determine the screen's clarity and layout.

Viewing Area and Active Display Area: Viewing area size is 62.0x44.0mm, active display area is 56.27x38.35mm, ensuring complete information display.

Temperature Characteristics: Operating temperature range is -20°C to +70°C, storage temperature can reach -30°C to +80°C, ensuring stable performance in various environments.

V. Other Process Features

Low Voltage and Low Power Consumption: The 12864 monochrome screen typically features low voltage and low power consumption, making it suitable for various low-power devices.

Multiple Interface Options: Offers various interface methods, such as parallel and serial interfaces, for easy connection with external devices.

Built-in Font Library: Some models of the 12864 monochrome screen come with a built-in Chinese character font library, enabling display of Chinese characters and ASCII characters for convenient Chinese applications.

The technology of the JGS12864W3201-12864 Graphic LCD Screen involves display technology, structure and materials, drive and control, performance parameters, and other process features. These characteristics make the 12864 monochrome screen widely applicable in various instruments, small devices, and other fields.
