This is a 2.1-inch circular touch screen specifically designed for smart home appliances and compact control panels. SKY-TDM can customize the display touch screen according to the actual structure of your equipment and the human-machine interaction (HMI) requirements.
This 2.1 inch circular touch display solution has a resolution of 480x480 and an approximate size of 56.18 x 59.71 x 2.26 millimeters. It is compact in structure. It uses the ST7701 driver IC and supports RGB interface (which can be customized as MIPI interface).
We provide customized display solutions to meet your core needs and help you seamlessly integrate display components into the overall industrial design of your equipment.
Round displays are increasingly replacing traditional square screens in smart home appliances.
Seamless Industrial Design: Circular displays eliminate the visual conflict between a rectangular screen and the curved, cylindrical forms common in coffee machines, air purifiers, and smart speakers. The screen integrates into the product silhouette rather than breaking it.
Knob Replacement: Many appliances still use physical rotary knobs for temperature, speed, or mode selection. A circular touch display can replicate the knob's function digitally with dynamic icons, adjustable sensitivity, and no mechanical wear, while offering more information than a printed dial.
Better Use of Compact Space: In small control panels, a circular layout avoids the wasted corner areas of rectangular screens. The 480×480 square pixel array maps naturally to a round viewing area, making full use of the available display region.
Stronger Visual Focus: Circular interfaces draw the user's eye to the center of the control panel, which is ideal for primary functions like start/stop, temperature adjustment, or mode selection in smart coffee machines and kitchen appliances.
Consistent Aesthetics Across Product Lines: Appliance brands can standardize on circular display modules across multiple products: coffee machines, air purifiers, washing machines creating a unified design language while simplifying procurement and inventory.
Touch + Display Integration: Combined with optical bonding and PCAP touch, a circular display becomes a sealed, easy-to-clean front panel, critical for kitchen appliances exposed to moisture, grease, and daily cleaning.
For smart home appliances, compared to traditional air-gap structures, optical Bonding delivers a more integrated display effect, highlighting the premium feel of the product.
By seamlessly bonding the touch panel to the display, this solution effectively minimizes visible light reflections caused by the air gap and prevents moisture ingress in varying humidity levels. It creates a much cleaner front surface, making it particularly ideal for home products with demanding aesthetic requirements.
This technology can be widely applied across various appliance designs, such as smart coffee machines, air purifiers, kitchen appliances, washing machine control panels, and smart ovens.
Featuring an extremely compact mechanical footprint of just 56.18 × 59.71 × 2.26 mm, 2.1 inch circular touch display solution is perfectly suited for applications with strict internal space constraints. Its 480x480 resolution delivers a square user interface that seamlessly integrates into the assembly of compact control panels.
We can discuss customized solutions with our clients based on the following workflow:
Display Size → Touch Panel → Cover Glass → Lamination → Interface Configuration → Mechanical Structure
Different projects may require varying screen dimensions, aspect ratios, mounting structures, or touch solutions tailored to specific use cases. Therefore, we highly recommend integrating custom development into the early design stage of your product. Through in-depth communication regarding your specific needs, we can provide superior customized solutions.
This 2.1 inch circular touch display solution assembly supports an I2C touch interface, allowing the touch function to be seamlessly integrated with the customer’s master control system.
In terms of display performance, the screen features a brightness of 300 cd/m² and an 800:1 contrast ratio. It offers wide viewing angles of up to 80° in all directions, and provides options for both RGB and MIPI display interfaces.

These outstanding characteristics lay a practical foundation for the interactive interfaces of compact home appliances, fully meeting users' human-machine interaction (HMI) needs.
Every customer device features a unique display interface and distinct industrial design. To serve our diverse customer base, we provide comprehensive OEM and ODM customization services. We can discuss tailored solutions based on your specific requirements, such as custom touch panels, custom cover glass, various interface options, customized FPC cables, logo silk-screen printing, and customized brightness and optical parameters.
In addition to our reference 2.1 inch circular touch display solution, we also offer integrated display driver board customization services, including options like serial port boards.
1.Requirement Confirmation: Share your display size, resolution, touch function, and installation space.
2.Solution Design: We propose touch panel, cover glass, and interface configuration.
3.Sample Development: Prototype assembly for your mechanical and electrical validation.
4.Design Verification: Joint review of fit, touch performance, and optical effect.
5.Mass Production: Stable batch supply with full inspection before shipment.
Early involvement is recommended: we can adapt the display assembly to your industrial design rather than forcing your design around a standard module.
Our display solutions are widely applicable to various smart home and appliance products, including:
Smart Coffee Machines: Touch controls provide a modern and interactive user interface.
Air Purifiers: Compact touch display assemblies allow for quick adjustment of various functions.
