4.9" TN TFT LCD Module

1. Specifications

Specification Notes

• TN / Normally White:
o Default display state is white when no voltage is applied
o Provides fast response time and cost-effective performance, with limited viewing angles

• 364×78 Resolution:
o Wide and narrow format, suitable for status bars or elongated displays
o Supports RGB sub-pixels for full-color rendering

• 6 o’clock Viewing Direction:
o Best image quality when viewed from below the display
o Viewing from other directions may result in contrast or color shift

• 3-wire SPI + 24-bit RGB Interface:
o SPI: Used for command and configuration
o 24-bit RGB: Handles pixel data for full-color display
o Combination ensures flexible control and fast data transfer
