Abstract
A stereoscopic display device and a control method thereof are disclosed. A liquid crystal display (LCD) panel of the stereoscopic display device is configured to display left-eye frames and right-eye frames alternately. Each of the left-eye frames includes a left-eye sub-frame and a black sub-frame that are displayed by a first display region and a second display region alternatively. Each of the right-eye frames includes a right-eye sub-frame and a black sub-frame that are displayed by the first display region and the second display region alternately. The backlight module includes a first backlight and a second backlight. The first backlight and the second backlight are turned on alternately in such a way that the first backlight illuminates the first display region when the first display region displays one of the left-eye sub-frames and the right-eye sub-frames and the second backlight illuminates the second display region when the second display region displays one of the left-eye sub-frames and the right-eye sub-frames. In this way, uniformity in brightness of the stereoscopic display device can be improved.
