概述

The JicTech JV028T1CSR-03B is a compact 2.8‑inch TFT LCD module designed for handheld and industrial applications that require a bright display with integrated resistive touch. Built on a TN panel (normally white) with EWV polarizer, it offers 240×RGB×320 pixel resolution, 262K colors, and a 12 o’clock optimal viewing direction. The 18‑bit RGB parallel interface simplifies connection to most MCUs, while the 480 cd/m² backlight ensures excellent indoor readability. An integrated 4‑wire resistive touch panel (RTP) with anti‑glare surface treatment provides reliable touch input even with gloves. With a slim 3.25mm overall thickness, this module is ideal for portable medical devices, industrial HMIs, handheld terminals, and consumer electronics.
