Abstract:
1. A display device configured to switch a display mode between a first display mode for time-divisionally displaying a left frame image, which is observed by a left eye, and a right frame image, which is observed by a right eye, to depict a stereoscopic video and a second display mode for time-divisionally displaying a first video and a second video, which are different in contents from each other, the display device comprising: a display portion which displays the stereoscopic video in the first display mode and the first and second videos in the second display mode; and a signal generator which generates a first control signal to notify a view start timing and a view end timing of the left and right frame images in the first display mode and a second control signal to notify a view start timing and a view end timing of one of the first and second videos in the second display mode, the first control signal having four types of command signals including a shared command signal which is commonly used in the first and second display modes, and the second control signal including the shared command signal and a first unshared command signal which is different from the four types of command signals, wherein the shared command signal of the second control signal notifies one of the view start timing and the view end timing of the one of the first and second videos, wherein the first unshared command signal of the second control signal notifies another of the view start timing and the view end timing of the one of the first and second videos, wherein, when the display mode is switched, the signal generator generates a stop signal, which stops an operation of an eyewear device that adjusts an image light amount to reach each of the left and right eyes so as to assist in viewing the stereoscopic video, the first video or the second video, wherein the stop signal includes the shared command signal and a second unshared command signal, and wherein the second unshared command signal is different from the four types of command signals and the first unshared command signal.
