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 monochrome or grayscale graphics with portrait orientation.
