概述

The JicTech RT028TR5T-M2 is a compact 2.8‑inch TFT LCD module designed for embedded applications that require a simple yet powerful MCU interface and good optical performance. Built on a TN panel (normally white) with EWV wide‑viewing polarizer, it offers 240×RGB×320 pixel resolution (QVGA), 65K colors, and a 6 o’clock optimal viewing direction. The 18‑bit MCU parallel interface (8080‑style) enables fast data transfer and easy connection to popular microcontrollers. With 300 cd/m² typical brightness, 500:1 contrast ratio, and a slim 3.5mm thickness, this module is ideal for handheld devices, medical equipment, portable terminals, industrial control panels, and consumer electronics.
