Abstract

The invention discloses a radio frequency charging system and a radio frequency charging method, which aim to charge a radio frequency device on a display panel and improve charging efficiency. The radio frequency device generates a response signal when receiving a radio frequency signal. The radio frequency charging system comprises an antenna group comprising a plurality of antennae, a switching unit, a radio frequency module and a micro-control unit, wherein the micro-control unit controls the switching unit to select an antenna from the antenna group capable of receiving the response signal to transmit the radio frequency signal so as to charge the radio frequency device.

Description

technical field [0001] The invention relates to radio frequency charging technology, especially a radio frequency charging system and method capable of charging a radio frequency device on a display panel. Background technique [0002] In recent years, radio frequency (radio frequency; RF) communication technology has developed a variety of short-range wireless communication applications, for example, in figure 1 In the shown surface computer (Surface Computer) 10, the radio frequency device 11 (such as mobile phone, radio frequency identification tag (radio frequency identification tag; RFIDtag) etc.) The radio frequency module 13 (including antenna and related radio frequency circuit) at the back communicates with a host computer 14 . For example, the radio frequency device 11 can transmit the photos stored in it to the host computer 14, and after processing and transmission by the host computer 14, it will be displayed on the display panel 12 around the location of the r...
