  • Patent number: 10878161
    Abstract: An integrated circuit includes an active zone extending in a first direction, and a spacer extending in a second direction perpendicular to the first direction. The spacer protrudes into a substrate and divides the active zone into a first part and a second part. The integrated circuit includes a first conductive segment and a second conductive segment each extending in the second direction and in a middle layer between the substrate and a metal layer. The first conductive segment forms conductive contact with an active region of a first transistor in the first part of the active zone, and the second conductive segment forms conductive contact with an active region of the second transistor in the second part of the active zone. The spacer joins the first conductive segment and the second conductive segment while electrically isolating the first conductive segment from the second conductive segment.

  • Patent number: 10845639
    Abstract: Disclosed herein is a display device for increasing the transmittance of R, G, and B sub-pixels and reducing a transmittance of W sub-pixel through a pixel asymmetric design. To this end, the display device has a pixel asymmetric structure in which W sub-pixel has a different area from R, G and B sub-pixels. As a result, as the display device has an asymmetric structure in which the areas of W, R, G, and B sub-pixels are different from one another, particularly, an asymmetric structure in which the area of W sub-pixel is reduced and the area of R sub-pixel is increased. Such design has a structural advantage that the transmittance of R, G, and B sub-pixels can be increased and the transmittance of W sub-pixel can be lowered so that it is possible to correspond the product specifications in various ways.
