Knob screen is a new type of human-computer interaction interface that deeply combines physical knobs with a touch screen display. It is not simply hardware or software, but a solution that tightly integrates hardware and UI design. The communication method used by this screen is TTL UART.
1.28吋圓形UART HMI顯示器的核心價值在於其極低的整合度和開發門檻,為需要小型、精緻、互動介面的產品提供了「即插即用」的解決方案。
1. 精準高效率的操作:旋轉旋鈕進行連續調整(如音量、溫度),相較於在螢幕上滑動,手感更好、更精準。
2.優秀的互動回饋:提供清晰的確認回饋,提升操作品質。
3. 簡潔的介面:透過螢幕定義的一個旋鈕可以實現多種功能,使控制區域變得簡單,同時提供無限的功能。
4.科技與品質:機械質感與數位螢幕的科技感完美融合,提升了產品的整體風格。
旋鈕螢幕主要用於智慧家庭和消費性電子領域。
For example Intelligent switch panel: replaces traditional switches to achieve scene control, temperature and humidity display, etc. Small household appliances: interactive interfaces for high-end coffee machines, air purifiers, humidifiers. As shown picture below:
