Abstract

A data transmission system includes a visual interface device and an operation device. The visual interface device includes a display panel and a control unit. The control unit receives display data and transmission data, and transmits the display data and the transmission data to the display panel. The operation device includes a capturing unit. A coupling signal containing the display data and the transmission data is coupled from an electrode of the display panel to the operation device when the visual interface unit is in operation, and the operation device utilizes the capturing unit to retrieve the transmission signal from the coupling signal.

Claims

1. A data transmission system comprising:

a visual interface device comprising a display panel and a control unit, wherein the display panel includes a pixel matrix including plural pixel electrodes, row electrodes and column electrodes, the control unit receives display data and transmission data, and transmits the display data and the transmission data to at least one of the row electrodes or the column electrodes of the pixel matrix of the display panel, the display data and the transmission data are different data; and

an operation device comprising an extracting unit, wherein the operation device and the visual interface device are located separately from each other;

wherein a coupling signal containing the display data and the transmission data is wirelessly coupled from the at least one of the row electrodes or the column electrodes of the pixel matrix of the display panel to the operation device when the operation device operates on the visual interface device, and the operation device retrieves the transmission data from the coupling signal by the extracting unit.

2. The data transmission system of claim 1 wherein the coupling signal comprises at least one tag and the operation device retrieves the transmission data according to the tag.

3. The data transmission system of claim 2 wherein the tag indicates, at least one of, the starting point, the endpoint, or the data size of the transmission data.

4. The data transmission system of claim 2 wherein the tag indicates, at least one of, the starting point, the endpoint, or the data size of the display data.

5. The data transmission system of claim 2 wherein the tag comprises, at least one of, an identification information of the visual interface device, an identification information of the operation device, or an error-correcting code.

6. The data transmission system of claim 2 wherein the signal between the display data and the transmission data with the tag has different characteristics in amplitude, frequency, phase, time, pulse width or data format.

7. The data transmission system of claim 1 wherein the extracting unit retrieves the transmission data according to the frequency range, time range, phase or amplitude.

8. The data transmission system of claim 1, wherein the control unit adds a tag into the display data and/or adds an additional tag into the transmission data, and the extracting unit distinguishes the display data and the transmission data according to the tag and/or the additional tag.

9. An operation device, adapted for being wirelessly coupled to a display panel wherein the display panel is located separately from the operation device and comprises a pixel matrix including plural pixel electrodes, row electrodes and column electrodes, comprising:

a coupling unit, wirelessly coupled to a signal transmitted from at least one of the row electrodes or the column electrodes of the pixel matrix of the display panel, wherein the signal carries display data and transmission data for the operation device and the display data and the transmission data are different data; and

an extracting unit, retrieving the transmission data from the coupled signal.

10. The operation device of claim 9, wherein the signal comprises at least one tag, and the operation device retrieves the transmission data according to the tag.

11. The operation device of claim 10, wherein the tag indicates, at least one of, the starting point, the endpoint, or the data size of the transmission data.

12. The operation device of claim 10, wherein the tag indicates, at least one of, the starting point, the endpoint, or the data size of the display data.

13. The operation device of claim 10, wherein the tag comprises, at least one of, an identification information of the visual interface device, an identification information of the operation device, or an error-correcting code.

14. The operation device of claim 10, wherein the signal between the display data and the transmission data with the tag has different characteristics in amplitude, frequency, phase, time, pulse width or data format.

15. The operation device of claim 9, wherein the extracting unit retrieves the transmission data according to the frequency range, time range, phase or amplitude of the coupled signal.

16. The operation device of claim 9, wherein the display data is added with a tag and/or the transmission data is added with an additional tag, and the extracting unit distinguishes the display data and the transmission data according to the tag and/or the additional tag.
