OG exemplary drawing
 
1. An image display system, configured to display a 3D image, wherein the image display system comprises a first image display device, a second image display device, and a 3D wearable device, and each of the first image display device and the second image display device comprises:
an image decoding circuit, configured to decode a 3D image signal from an external signal source, so as to obtain and output an image data signal and a synchronization signal;
a 3D image processing circuit, receiving the image data signal and the synchronization signal from the image decoding circuit, and configured to perform 3D image processing on the image data signal and the synchronization signal, so as to generate and output a processed image data signal and a processed synchronization signal,
wherein the 3D image processing circuit further comprises a viewing angle switching circuit configured to generate and output a processed viewing angle switching signal according to the processed synchronization signal; and
an image playback circuit, configured to receive the processed image data signal, and generate and output a playback image signal according to the processed image data signal,
wherein the image display system generates the 3D image according to the processed viewing angle switching signal and the playback image signal,
wherein the first image display device and the second image display device respectively receive the 3D image signal from the external signal source, and respectively output the playback image signal at a same timing,
wherein the 3D wearable device is electrically connected to one of the first image display device and the second image display device, and is configured to receive the processed viewing angle switching signal from the one of the first image display device and the second image display device, and the 3D wearable device is operated according to the processed viewing angle switching signal when the image display system displays the 3D image.
