  • Patent number: 10558080
    Abstract: A segmented transparent LCD is disclosed that includes a LC module that is substantially transparent to visible light. The segmented transparent LCD includes an array of spaced apart display segments supported by the LCD module. Each display segment is configured to display a segment of the display image. Each display segment includes a non-specular light-redirecting segment configured to provide localized backlight to the display segment when the ambient light is incident thereon. The segmented transparent LCD allows for a display image to be displayed and viewed while also allowing a viewer to see through one or more transparent regions that separate the display segments. Methods of displaying a display image using the segmented transparent LCD are also disclosed.

  • Patent number: 10288945
    Abstract: A reliability of seal portion of a liquid crystal display device can be improved by the following structure. A liquid crystal display device includes: a TFT substrate which includes a display region and a terminal part, and has an inorganic insulating film formed on an organic passivation film and an alignment film formed over the inorganic insulating film; a counter substrate, the TFT substrate and the counter substrate bonded together by a sealing material formed at a seal part surrounding the display region; and a liquid crystal sealed inside. At the seal part, a transparent conductive oxide film is formed between the inorganic insulating film and the alignment film. The transparent conductive oxide film exists inside an edge of the TFT substrate and hence, the edge of the TFT substrate is free of the transparent conductive oxide film.

  • Patent number: 9740062
    Abstract: A pixel electrode is configured of one comb tooth portion and a contact portion whose width is widened from the end portion of the comb tooth portion in a first direction that is the extending direction of a scanning line. The width of the contact portion is not expanded in a direction opposite to the first direction, and the production of a domain is prevented. A picture signal line is bent in the direction in which the width of the contact portion of the pixel electrode is widened, so that the comb tooth portion of the pixel electrode can be disposed in the center between the picture signal lines, and the width of the contact portion can be formed in a sufficient width in the direction in which the picture signal line is bent. Thus, the contact margin of the pixel electrode can be provided.
