2.7 inch TFT LCD TN 320 (RGB) × 240 Display Module

2.7" TN TFT LCD Module

1. Specifications

Specification Notes

· TN / Normally White:

o Default display state is white when no voltage is applied.

o Offers fast response time and cost-effective performance, but with limited viewing angles.

· 320×240 Resolution:

o Standard QVGA resolution with RGB sub-pixels.

o Suitable for graphical user interfaces, icons, and text display.

· 9 o’clock Viewing Direction:

o Best image quality when viewed from the left side of the display.

o Viewing from other directions may result in contrast or color shift.

· 8-bit RGB + 3-wire SPI Interface:

o RGB (8-bit): Handles pixel data transmission.

o 3-wire SPI: Used for command control and register configuration.

o Combination provides a balance between performance and pin efficiency.

2. Functions
