1.28 inch HMI
As a leading display manufacturer in China, Seeenka Electronics has launched the 1.28-inch rotary knob display (CNKHTLQVGA0128C-01), redefining HMI standards for smart appliances and industrial systems.
Combining IPS LCD technology, a 240×240 resolution, and 300 cd/m² brightness, it delivers crisp visuals with a 178° viewing angle. A UART interface and a 5V low-power design ensure seamless integration, while its operating temperature range of –20°C to 70°C and IP65 protection (customizable) enable it to withstand harsh environments.
This display features Wi‑Fi and Bluetooth connectivity, enabling remote control and cloud‑based data collaboration. The Open SDK supports accelerated UI customization for a wide range of applications. As a manufacturer of monochrome displays, CNK offers cost‑effective solutions for industrial equipment, with specialized expertise in shape adaptation (including a compact 50 mm design), multi‑protocol compatibility (LVDS/SPI), and hybrid touch‑rotary interfaces.
Widely used in smart kitchens, industrial PLCs, and medical applications.
