2.8 Inch TN TFT LCD Module Display Resolution 240×320

2.8" 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 narrower viewing angles compared to other technologies.

• 240×320 Resolution:
o QVGA resolution with RGB sub-pixels.
o Suitable for displaying text, graphics, icons, and basic UI elements.

• 6 o’clock Viewing Direction:
o Best visual performance when viewed from below the display.
o Viewing from other angles may cause contrast or color shifting.

• 8-bit MPU Interface:
o Supports parallel communication with microcontrollers.
o Commonly used in embedded systems for command and data transfer.
o Balances simplicity and compatibility with various MCU platforms.
