  • Publication number: 20200133055
    Abstract: A color display device comprises an array of a plurality of sub-pixels including a red sub-pixel, a blue sub-pixel, a first green sub-pixel and a second green sub-pixel. The first green sub-pixel and the second green sub-pixel are smaller than that of the red sub-pixel or the blue sub-pixel. The two adjacent first green sub-pixels are arranged in a first direction, the two adjacent second green sub-pixels are arranged in the first direction. The blue sub-pixel is directly adjacent to the red sub-pixel in a second direction; the blue sub-pixel is directly adjacent to the two first green sub-pixels and the two second green sub-pixels.

  • Patent number: 10551664
    Abstract: In a color display device, when using white (W) sub-pixels in addition to subpixels of red (R) and green (G) plus blue (B) without increasing a wiring line number, the per-color pixel number in a unit area decreases so that the image resolution is deteriorated. The area and number of subpixels are adjusted in accordance with the visual sensitivity or luminosity required. Practically, the area of red (R) and blue (B) subpixels which are relatively low in luminosity is set to be about two times greater than the area of green (G) and white (W) subpixels that are relatively high in luminosity while letting the number of green (G) and white (W) subpixels be twice the number of red (R) and blue (B) subpixels. A larger subpixel is configured from a plurality of unit subpixels. A smaller subpixel is formed of a one unit subpixel.

  • Patent number: 10287652
    Abstract: The purpose of the present invention is to provide a method for recovering calcium-containing solid components from steelmaking slag, with which it is possible to easily increase the calcium recovery rate. With the method, steelmaking slag is immersed in an aqueous solution containing carbon dioxide, and calcium in the steelmaking slag is made to leach out into the aqueous solution. Next, the immersed steelmaking slag is removed from the aqueous solution, and, subsequently, the pH of the aqueous solution is increased. When solid components precipitated by doing so are recovered, it is possible to recover solid components containing 20% or more by mass in terms of calcium atoms.
