  • Patent number: 10606541
    Abstract: A display device or an electronic device with high portability and browsability is provided. A display device which includes two display panels that overlap with each other and in which the area of a portion where the two display panels overlap with each other is variable is provided. The larger the area where the two display panels overlap with each other is, the smaller the display device becomes. The first display panel includes a first region that performs display. The second display panel includes a second region that performs display, and a third region that is adjacent to the second region and transmits visible light. When the third region overlaps with the side of a surface which performs display of the first region, display can be performed using a seamless large display region.

  • Publication number: 20190226381
    Abstract: An energy conversion device includes a first acoustic wave generator, a second acoustic wave generator, and an output unit which are provided in a pipe member. The first acoustic wave generator has a thermal energy generator configured to generate thermal energy from electric energy, and converts the thermal energy generated by the thermal energy generator into acoustic energy to generate acoustic wave in working gas by a self-excited thermo acoustic vibration. The second acoustic wave generator converts thermal energy supplied from a heat supply source into acoustic energy and generates acoustic wave in working gas by a self-excited thermo acoustic vibration. The output unit converts the acoustic energy of the acoustic waves from the first acoustic wave generator and the second acoustic wave generator into cold energy to output.

  • Publication number: 20190008014
    Abstract: 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.

  • Patent number: 10056043
    Abstract: A display system including a display device and an image processing device is provided. The display device includes a second display panel overlapping with a first display panel on the display surface side. The second display panel has a region that transmits visible light adjacent to a display region. The region that transmits visible light of the second display panel overlaps with a display region of the first display panel, which makes a non-display region between display regions of two display panels in the display device small. The image processing device has a function of correcting the gray scale, which is included in image data, corresponding to at least one of a portion overlapping with the region that transmits visible light and a portion not overlapping with the region in the display region of the first display panel.
