  • Publication number: 20230422543
    Abstract: A display module includes a window including a base substrate and a bezel pattern overlapping the base substrate in a plan view, and a display panel. The bezel pattern includes a first bezel pattern extending along an edge of the base substrate, and a second bezel pattern which extends from the first bezel pattern and of which at least a portion defines a transmission area. The display panel includes a glass substrate, an encapsulation substrate on the glass substrate, a sealing member coupling the glass substrate and the encapsulation substrate and overlapping the first bezel pattern in the plan view, a circuit element layer disposed on the glass substrate and including a transistor, and a display element layer disposed on the circuit element layer and including light emitting elements. The display element layer exposes a portion of a layer disposed thereunder, which corresponds to the transmission area.

  • Patent number: 8199517
    Abstract: Provided are a flexible printed circuit board (PCB), which can contribute to the reduction of damage to wiring layers and wiring defects regardless of a decrease in the width of wiring layers and can thus contribute to the miniaturization of various products, a method of fabricating the flexible PCB, and a display device having the flexible PCB. The flexible PCB includes a base film, one or more first pad patterns formed on the base film, one or more second pad patterns formed on the base film and connected to the one or more first pad patterns, a cover film formed on the one or more first pad patterns and the base film and exposing the one or more second patterns, and a plurality of expanded portions corresponding to the boundaries between the one or more first pad patterns and the one or more second pad patterns and having a greater width than the one or more first pad patterns and the one or more second pad patterns.
