HMI Solutions

HMI (Human-Machine Interface) is the bridge between users and equipment. GPT LCM provides a full range of HMI solutions from monochrome segments to color TFTs, covering industrial control, smart home, medical devices, and consumer electronics applications.

Industrial HMI Panels

Industrial HMIs must deliver stable and reliable touch interaction in harsh environments. GPT LCM 4.3–7 inch TFT serial displays support resistive and capacitive touch, with -20°C to +70°C wide temperature operation and anti-vibration/anti-interference design suitable for factory floors. Visual OCM configuration software offers rich controls including buttons, sliders, charts, and curves with drag-and-drop design—no programming required. From prototype to mass production in as little as one week.

Smart Home Panels

Smart switches, air conditioning panels, and access control intercoms require attractive color touch interfaces. GPT LCM 2.8–5 inch TFT serial displays support Chinese/English multi-language display, image loading, and animation effects with simple, easy-to-use command sets. OLED displays offer self-emission and high contrast, ideal for status display and information push in premium smart home products.

Consumer Electronics / Education & Development

Maker development boards, DIY electronics projects, and STEM education kits need simple, easy-to-use display solutions. GPT LCM small serial displays (1.3–2.8 inches) can be driven via UART with just two wires, requiring no complex timing control. Reference code and tutorials are available for Arduino, ESP32, Raspberry Pi, and other mainstream platforms, perfect for beginners to get started quickly.

Medical / Laboratory Equipment

Medical monitors and laboratory analyzers require HMI interfaces that are clear, responsive, and intuitive. GPT LCM TFT serial displays support multi-window layouts for simultaneous display of parameters, waveforms, and alarm information. Resistive touch support allows gloved operation, suitable for medical and laboratory environments.

All HMI products come with complete development documentation, reference code, and selection guides to help customers from solution evaluation to mass production. Multiple communication interfaces (UART/RS232/RS485) are available with adjustable baud rates, compatible with various controllers.
