2. Functional Features
2.1 5.7‑Inch Industrial Color TFT High‑definition Display for Hierarchical Process Visualization
It adopts a 5.7‑inch industrial‑grade color active‑matrix TFT‑LCD display with physical resolution of 320×240 pixels and supports 18‑bit true‑color output, delivering rich color gradation, clear working‑condition distinction and high parameter recognizability. Fitted with industrial long‑life white LED backlight with service life over 25 000 hours, it provides uniform brightness and stable color performance against strong‑light direct sunlight, dim‑light conditions and sharp temperature swings on‑site. Different from conventional monochrome terminals, it differentiates equipment status such as normal operation, warning, fault shutdown, standby and debugging by color coding. It supports display of complex process screens, multi‑segment workflow diagrams and multi‑point centralized parameter panels, eliminating pain points of monochrome units including simplistic visuals, vague status discrimination and insufficient visualization capability. It perfectly fits industrial scenarios requiring refined process control, multi‑parameter monitoring and multi‑level alarm prompts. It avoids black screen under cold startup, screen distortion at high temperature, color fading and image ghosting during long‑time runtime, and guarantees accurate round‑the‑clock visualization of production conditions.
2.2 Dual‑redundant Touch‑and‑keypad Operation for High‑intensity All‑condition Compatibility
It features exclusive industrial hybrid‑operation design integrating high‑precision 4‑wire analog resistive touch screen and integrated stainless‑steel membrane function keys, combining fine‑grained touch‑operation convenience and high‑strength durability of physical keys.
