Graphic LCD Module Design Manual

┃What Is a Graphic LCD Module?

Graphic LCD Modules provide direct control over individual pixels, supporting bitmap graphics, text rendering, icons, and data visualization in both dynamic and static formats. Compared to character LCDs, these modules offer enhanced versatility and data display capacity. Commonly used in instrumentation, industrial automation, telecom, medical systems, and consumer devices.

Key Features

• Dot-matrix control for graphics and international font sets

• Resolution options: 128×32, 128×64, 160×128, 240×64, 240×128

• Interface support: Parallel, SPI, I²C

• Compatible with LED backlights (white, blue, yellow-green)

• Customizable options include glass size, touch panels, and FPC design

┃Recommendations

• The logic voltage of the LCD controller must be compatible with the main processor.

• Signal lines should be kept short with appropriate termination for signal integrity.

• Focus on optimizing the backlight driver and thermal management to ensure system stability.

• Avoid crossing data lines with backlight power in the PCB layout to prevent interference.

• Choose appropriate temperature ranges and humidity protection based on the specific environmental conditions.

┃Product Overview

When the character display's limitations in information density and layout become apparent, graphic LCD modules are the optimal upgrade. These modules provide pixel-level control, enabling the display of multi-language fonts, graphs, icons, and real-time data screens, suitable for applications requiring more versatile information presentation. Eileen Technology offers a wide range of resolutions and visible area designs, from monochrome to grayscale, and interfaces from SPI to parallel. These modules enable the creation of embedded display interfaces that balance both functionality and visual clarity. They are well-suited for medical, instrumentation, handheld devices, and smart terminal applications.
