Écran TFT série RS485 UART | Industrial HMI Screen Solution‑NISINOPTO Meta description: NISINOPTO supplies 0.77‑24 inch RS485 serial port TFT screens. Support RS232, Durée de vie, wide‑temperature operation and zero‑code UI configuration for industrial equipment HMI.
Introduction
Industrial display projects frequently run into common obstacles, including complicated driver programming, lengthy R&Cycles D, poor signal stability under heavy electromagnetic interference and extreme temperature fluctuation. Long‑distance wiring and multi‑device networking will easily trigger signal attenuation and transmission failure for ordinary display interfaces.
Shenzhen NISINOPTO now releases the upgraded RS485‑compatible smart serial screen series. We supply one‑stop technical support from solution design to mass‑production delivery and deliver stable, customizable human‑machine interaction for harsh industrial‑site conditions.
Core Benefits of Our RS485 Serial Display Solution
1. Industrial‑grade RS485 differential communication
Our 4.3‑inch TFT serial screen supports RS232 and RS485 protocols. The differential‑signal transmission technology excels at long‑distance wiring and anti‑interference performance. Common application scenarios:
- PLC human‑machine interface
- Industrial data collector
- Vehicle‑mounted control panel
2. Multiple communication protocols compatible
All display modules accept TTL, UART, RS232 and RS485 signals. You may adjust interface definition according to your main‑control chip hardware features. It cuts hardware‑modification costs in later‑stage integration.
3. Wide‑temperature and outdoor‑usable TFT screens
The 7‑inch industrial TFT display works stably from ‑40℃ to 85℃. AG anti‑glare, AR anti‑reflection and AF oleophobic coatings are optional. It retains stable touch sensitivity and clear viewing under humid and fluctuating‑temperature outdoor environments. Suitable for charging piles, security main controllers and onboard control hardware.
4. Zero‑code UI configuration with LT7589 main IC
Our 5‑inch serial TFT screen is equipped with LT7589 controller chip. Visual HMI configuration removes heavy low‑level driver coding work and greatly shortens your product development cycle.
5. Expandable flash storage and flexible firmware upgrade
Built‑in external Flash ranges from 64M to 1GB on different models. USB and SD‑card firmware update are supported. You can store multi‑language UI packages and large image galleries, and conduct on‑site or remote program upgrades conveniently.
6. Resistive and capacitive touch options
- RTP resistive touch: Support gloved operation, heavy‑pressure touch and oily‑site usage
- CTP capacitive touch: Smooth operation and multi‑touch gesture function
7. Full‑size product portfolio
Display dimension covers 0.77 inch up to 24 pouce, covering wearable panels, laboratory meters and large‑size industrial control terminals.
Protocoles de communication & Internal Controller Explanation
- RS485: 2‑wire differential bus signal, outstanding anti‑interference and long‑range transmission, ideal for multi‑slave industrial bus networking
- RS232: Single‑end signal, designed for short‑distance point‑to‑point communication
- Durée de vie / UART: Chip‑level serial signal for short‑range motherboard connection
Two built‑in drive IC solutions:
- LT168A/B: Render images, parse serial instructions and manage external flash to reduce MCU workload for simple UI projects
- LT7589: Dedicated configuration chip for complex HMI and no‑code screen editing
Manufacturing craftsmanship All panels adopt automatic COF bonding and full‑lamination assembly lines, improving structural stability and optical performance of LCM modules.
Three‑Tier Customization Service
