  • Patent number: 10663834
    Abstract: A constitution of the display device of the invention is shown in the following. The display device includes a pixel unit including TFTs of which the active layer contains an organic semiconductor material for forming channel portions in the opening portions in an insulating layer arranged to meet the gate electrodes. The pixel unit further includes a contrast media formed on the electrodes connected to the TFTs for changing the reflectivity upon the application of an electric field, or microcapsules containing electrically charged particles that change the reflectivity upon the application of an electric field. The pixel unit is sandwiched by plastic substrates, and barrier layers including an inorganic insulating material are provided between the plastic substrates and the pixel unit. The purpose of the present invention is to supply display devices which are excellent in productivity, light in weight and flexible.

  • Publication number: 20190355303
    Abstract: In a display element such as an organic EL element, deterioration progresses due to light emission, and emission luminance is lowered even if the same voltage is applied to the display element. Therefore, use over time causes variations in luminance of each pixel, thereby a so-called “image burn-in” phenomenon occurs. Given this factor, the invention provides a display device which can reduce the difference in deterioration of a display element in each pixel and suppress variations in light emission of a display element in a pixel. It is prevented that only a specific pixel has a long accumulated lighting time. For that purpose, a gray scale of a display pattern is changed to prevent the difference in deterioration of display element in pixels from increasing. Alternatively, a specific display pattern is prevented from being fixedly displayed in a specific region.
