Abstract
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.

14. A puzzle system, comprising:
-
a plurality of puzzle pieces, and each puzzle piece including a radio frequency identification (RFID) module, a display panel and a display driving module, and the RFID module being provided for storing an identification code; a puzzle platform, for placing the puzzle pieces; a plurality of RF readers, installed at the puzzle platform, and each RF reader emitting a radio signal for reading the identification code; a storage device, installed at the puzzle platform, for recording a correspondence of data of the identification codes and the RF readers; and a processing device, installed at the puzzle platform, capable of receiving the identification code read by each of the RF readers, and determining whether or not each of the RF readers is matched with the identification code read by the RF reader according to the correspondence data;
if yes, then the processing device controls the matched RF reader to continue emitting a radio signal;wherein, when the RFID module of the puzzle piece receives the radio signal, the RFID module generates a power which is provided to the display driving module, such that the display driving module drives the display panel to change a display state, and allow the puzzle piece to expose a puzzle image. - View Dependent Claims (15, 16, 17, 18)
