*for touch version only
Supports high-quality audio processing, providing clear and high-quality audio input and output
Allows access to online large model platforms such as DeepSeek, Doubao, etc
E-paper display utilizes microcapsule electrophoretic technology for displaying, the principle is: charged particles suspended in clear fluid will move to sides of microcapsule when electric field is applied, making the microcapsule become visible by reflecting ambient light, just as traditional printed paper.
E-paper display will clearly display images/texts under lamplight or natural light, requires no backlight, and features nearly up to 180° viewing angle. It is usually used as e-reader due to its paper-like effect.
Suitable for Voice Interaction and e-Reader, etc
