Overview
The JicTech RSH043I5BSC-12 is a high‑performance 4.3‑inch TFT LCD module designed for demanding industrial and consumer applications. Built on an IPS panel (normally black) with 800×RGB×480 pixel resolution, it offers true 16.7M colors and ultra‑wide viewing angles (80° in all directions). The 24‑bit RGB interface provides smooth, full‑color video, while the 850 cd/m² backlight ensures excellent sunlight readability. An integrated capacitive touch panel (FT5446 driver) is available on the same module, making it ideal for interactive HMIs, medical devices, automotive displays, and portable terminals.
