    Abstract: The present disclosure relates to a testing method of a 3D display cross interference and the testing device thereof. The method according to the present disclosure comprises: acquiring a brightness of at least one first test image in a region where a left eye image is displayed in a display device and a brightness of at least one second test image in a region where a right eye image is displayed in the display device through a left eye lens or a right eye lens of stereo glasses; comparing the brightness of the acquired first test image and the brightness of the acquired second test image, and determining a cross interference value or a cross interference value range between the left eye image and the right eye image according to the comparison result, a grey scale value of the first test image and a grey scale value of the second test image. By using the method according to the embodiment of the present disclosure, the cross interference value or the cross interference value range between the left eye image and the right eye image of the stereo display system is able to be tested quickly so that the processing speed and efficiency of the cross interference test are enhanced.
