Grayscale Display Technology
This module is a grayscale TFT display, not a full-color TFT. It supports flexible grayscale configurations:
- 16 Gray Scales (4BPP) – 4 bits per pixel for smooth gradient and detailed imagery
- 4 Gray Scales (2BPP) – 2 bits per pixel for reduced data requirements
- 2 Gray Scales (1BPP) – 1 bit per pixel for simple high-contrast monochrome display
This makes the display ideal for applications requiring high-contrast grayscale graphics with standard 4:3 aspect ratio.
Applications
This grayscale TFT LCD module is designed for a variety of industrial, medical, and professional applications where high-contrast grayscale graphics with 4:3 format are required:
- Industrial Control Panels – HMI interfaces, machine controls, and process monitoring displays
