The Knob Screen is an innovative display module that combines traditional knob control and display functions. This screen not only has the graphic or text display function of a conventional display but also integrates a knob-type input device so that users can interact with the device by rotating and pressing the knob. Knob Screen usually uses a small-sized LCD or OLED display that can display necessary parameters, ícones, text or menus. The size is generally between 0.96 e 2.4 polegadas, and the resolution is relatively low, but it is sufficient to meet the functional display requirements. The characteristics of Knob Screen are that the knob and the screen are combined into one, the operation is intuitive, the space is saved, and the visual feedback is timely. It is widely used in car center consoles and dashboards, high-end home appliances such as washing machines, ovens, refrigerators and coffee machines, audio and mixing consoles, industrial equipment, equipamento médico, dispositivos portáteis, e outras indústrias.
