LCD Module Launched for Alarm Units and Compact Terminals

The module uses COB packaging and a standard 16-pin interface, supports 3.3V/5V dual-voltage power supply, and is compatible with 8-bit/4-bit parallel as well as simplified I2C and SPI interfaces. It can be quickly connected to mainstream control platforms such as STM32, Arduino and GD32, greatly shortening the development cycle of terminal products.

For the demanding application requirements of **alarm units and compact terminal devices**, the module offers multiple advantages:

- **Wide-temperature stability**: Operating temperature range of -20℃ to 70℃, suitable for long-term stable operation of indoor and outdoor security terminals
- **Low power & long life**: Low-power LED backlight with long service life, ideal for battery-powered and 24/7 working scenarios
- **Compact & integrable**: Standard small size, easy to embed into alarm hosts, emergency call boxes, access control terminals, portable detectors and other space-limited equipment
- **Intuitive status display**: Real-time display of alarm codes, arm/disarm status, fault information, time/date and channel parameters
- **High anti-interference**: Industrial-grade design, suitable for security and industrial terminals in strong electromagnetic environments

With mature design and stable performance, the 1602A blue-film LCD module is widely used in:

- Alarm units: Fire alarm control panels, gas alarm hosts, emergency call boxes, one-key alarm terminals, perimeter zone displays
- Compact terminals: Access control readers, portable detectors, IoT acquisition terminals, small industrial control panels, battery-powered smart terminals

Driven by the trends of intelligent security and miniaturized IoT terminals, the demand for **compact, reliable and cost-effective** character displays continues to grow. With standardized interfaces, mature solutions and large-scale delivery capability, the 1602A module effectively balances performance and cost, helping terminal manufacturers accelerate product launch and enhance market competitiveness.

Going forward, the company will continue to launch thinner, lower-power, automotive-grade and industrial-grade character LCD modules, and further optimize I2C/SPI interface versions to better fit alarm units, compact terminals and battery-powered devices, empowering the global security and IoT industry with technological innovation and quality assurance.
