Patent number: 10534401Abstract: A display device or a display system with which a viewer can feel a strong or natural stereoscopic effect in a two-dimensional image and is less likely to be fatigued is provided. The display system includes a display portion, a detection portion, and a control portion. The display portion is flexible.

Publication number: 20190008014Abstract: A display device that can display an image along a curved surface is provided. In the display device, a first display panel and a second display panel overlap each other with a light-transmitting layer provided therebetween. The light-transmitting layer is positioned on a display surface side of the first display panel, and on a side opposite to the display surface of the second display panel. The light-transmitting layer has an average transmittance of 80% or more with respect to light in the wavelength range of 450 nm to 700 nm and a refractive index higher than that of air. A display region of the first display panel overlaps a region transmitting visible light of the second display panel with the light-transmitting layer provided therebetween. It is preferred that the display region of the first display panel not overlap with a region blocking visible light of the second display panel.Type: ApplicationFiled: September 5, 2018Publication date: January 3, 2019Inventors: Hisao IKEDA, Nozomu SUGISAWA, Yuichi YANAGISAWA
