The above described objects, features, and advantages of the present invention will become more apparent from the description of the appended claims appended claims A good example. It is to be understood that the invention is not limited to the scope of the invention.

Figure 1 is a block diagram showing a display system in accordance with an embodiment of the present invention. As shown in FIG. 1, the display system 100 has a mobile device 110 and a display device 120. The mobile device 110 includes a controller 111, a first wireless network module 112, and a wireless power transmitter 113. According to an embodiment of the present invention, when the mobile device 110 is close to the display device 120, the controller 111 first activates the power transmitter 113 and controls the wireless power S _P transmitted by the wireless power transmitter 113 when the display device 120 receives the wireless power. When the S _P is connected to the mobile device 110, the controller 111 transmits the image data S ₁ to the display device 120 via the first wireless network module 112. The display device 120 includes a wireless power receiver 121, a power processing module 122, a second wireless network module 123, a processor 124, and a display 125. The power processing module 122 is coupled to the wireless power receiver 121, and provides the internal power source P to the second wireless network module 123, the processor 124, and the display 125. The processor 124 is coupled to the second wireless network module. 123 and the display 125.

Wireless charging, also known as inductive charging, non-contact inductive charging, utilizes near-field sensing, that is, inductive coupling, by the mobile device 110 through the wireless The power transmitter 113 delivers energy to the wireless power receiver 121 of the display device 120, which uses the received energy for its own operation. Since the mobile device 110 and the display device 120 transmit energy by inductive coupling, and there is no wire connection between the two, the mobile device 110 and the display device 120 can be exposed without conductive contacts.

According to one embodiment of the present invention, when the mobile device 120 close to the display device 110, the wireless power receiver 121 receives the wireless power transmitter 113 transmits the wireless power _P S, P is conveyed and the internal power supply 122 to the power processing module. After receiving the internal power source P, the power processing module 122 supplies the power to the second wireless network module 123, the processor 124, and the display 125, respectively, while the second wireless network module 123, the processor 124, and the display 125 are thus start up.

According to one embodiment of the present invention, when the wireless power receiver 121 receives the wireless power S _P is started when the processor 124, the processor 124 controls the second wireless network module 123 establishes a first wireless network module 112 The first wireless network module 112 transmits the image data S _I to the second wireless network module 123 through the point-to-point connection, and the processor 124 then receives the image data S received by the second wireless network module 123. After the processing of _I , the transmitted processed image data S _I ' is displayed on the display 125. In accordance with an embodiment of the invention, the point-to-point connection is a point-to-point connection between wireless networks. According to an embodiment of the invention, the display 125 has a timing control circuit 126 that receives the processed image data S _I ' of the processor 124 and controls the timing of the processed image data S _I ' to be displayed on the display 125.

Therefore, the display device 120 can be placed independently without connecting the power line or the data transmission line, and only the mobile device 110 with the built-in wireless network module and the wireless power transmitter should be close to the display device 120. Here, the mobile device 110 Can be in any form.

2 is a flow chart showing an image data and wireless power transmission method according to an embodiment of the present invention. For the sake of clarity, the flow chart of Figure 2 below will be combined with Figure 1. When the device 120 is a mobile device of FIG.'S 1 110 closer to the display, the wireless power S _P by the mobile device 110 is wirelessly transmitted to the display device 120 (step 201); The receiver of the wireless power S _P, starts the display device 120 (step 202) ; mobile device 110 and display device 120 to establish a point to point connection (step 203); a mobile device 110 via a connection point S _I transmitted image data to the display device 120 (step 204); and a display device 120 displays the image data S _I (step 205). At step 205, when the mobile device 110 changes the image data S _I, the process returns to step 204, again via the mobile device 110 updates the connection point S _I transmitted image data to the display device 120.

The display device 120 proposed by the present invention can be separated from the power supply line and the data transmission line by using the wireless charging and wireless transmission technologies. The display device 120 is highly flexible and convenient for the user to share with the public. Digital content, or convenient for users to use in their presentations.
