Solution:

This 2.1-inch smart rotary screen is specifically designed for car refrigerators in recreational vehicles, addressing issues such as the clunky operation interface, unclear information display, and poor environmental adaptability of traditional car refrigerators. By integrating a rotary knob with a high-definition display, users can intuitively and stably adjust temperature and modes, and view the operating status in real-time, even during bumpy driving or in strong outdoor light conditions, greatly enhancing convenience and safety of use.

Product advantages

High reliability and wide temperature adaptability: Operating temperature range from -20 to 70℃, adapting to high temperatures inside vehicles and severe cold outdoor environments, ensuring stable operation;

High-definition full-view display: With a resolution of 480*480 and a full-view round screen, it remains clear and readable even under strong light;

Compact and shock-resistant design: With an external dimension of only Ø71.3mm, the structure is sturdy, making it suitable for in-vehicle installation and frequent vibration scenarios;

Easy to integrate and develop: Utilizing a standard TTL serial port, it supports rapid integration with various in-vehicle control systems, thereby shortening the time to market for customer products.

This display has been successfully applied to multiple high-end RV refrigerators, helping customers create a more intelligent, reliable, and user-friendly on-board refrigeration solution, thereby enhancing product competitiveness and brand value.
