摘要 |
This invention discloses a RF sensing system, a RF display device and a puzzle system using the same. The RF sensing system includes a platform, at least one RF reader and a RF display device. The RF reader is installed at the platform for generating a radio signal. The RF display device includes a display panel and a flat panel. If the RF display device receives the radio signal, the display panel can change a display state. The flat panel has a text or an image. If the display panel is at an opaque state, at least a portion of the text or the image is blocked by the display panel. If the display panel is at a transparent state, the text or the image is exposed. If the flat panel has a puzzle pattern, several RF display devices can be used for forming a puzzle. |
