As the wave of intelligent technology sweeps across industries, the human-computer interface (HMI) has become a key differentiator for products. A 2.76-inch rotary display, a smart module integrating a physical knob with a high-definition display, is quietly changing the way we interact with devices, from desk lamps to car dashboards.
Sophisticated Design, Powerful Functionality
This display utilizes a high-resolution 480×480 IPS panel, with a display size precisely controlled at 70.13mm. The overall dimensions are a mere 92.45mm x 35.54mm, making it a compact and powerful device. A brightness of 350 nits ensures clear display in all lighting conditions, while a wide operating temperature range of -20°C to +70°C makes it suitable for a wide range of applications, from home appliances to automotive applications.
Most striking is its innovative interaction method: in addition to supporting traditional touch controls, it also features a built-in physical encoder, allowing users to precisely operate and select functions by rotating and pressing the knob. This dual “physical + digital” interaction model retains the tactile feedback of traditional controls while incorporating the intuitiveness and richness of digital displays.
Wide Applications, Unlimited Possibilities
This display has a surprisingly wide range of applications:
Home Use: Brightness and Color Temperature Adjustment for Smart Desk Lamps, Height Control for Adjustable Desks, and Centralized Light Switch Management
Kitchen Appliances: Mode Selection for Coffee Machines, Programming for Washing Machines, Function Adjustment for Dishwashers, Integrated Oven Operation, Temperature and Time Settings for Air Fryers, and Filter Status Display for Water Purifiers
Health and Leisure: Program Selection for Massage Chairs
Automotive: Quick Operation of Central Control Systems
Developer-Friendly, Customizable
The TTL interface and support for the UI Editor platform significantly lower the development barrier. Manufacturers can quickly develop customized products, transforming unique product concepts into intuitive and easy-to-use interfaces, shortening time to market.
A New Perspective on the Interactive Experience
The success of this rotary display lies not only in its technical specifications but also in its deep understanding of human-centric interaction. In an era of ubiquitous touchscreens, this device demonstrates the value of combining physical controls with digital displays—it delivers the intuitive feel of physical controls while offering the flexibility and rich information of digital interfaces.
This interaction mode is particularly well-suited for scenarios requiring quick adjustments, precise control, or blind operation, allowing users to focus more on completing tasks without relying solely on visual confirmation.
With the continuous development of IoT technology, this humanistic interaction design will become a crucial bridge between the physical and digital worlds, bringing a more natural and intuitive operating experience to smart devices.
Whether you’re a product designer, hardware engineer, or tech enthusiast, this 2.76-inch rotary display deserves your attention—it may be the next evolution of smart device interaction.
