Abstract: A method of manufacturing a display device is disclosed. In one aspect, the method includes forming an active layer over a substrate, forming a first insulating layer over the active layer, forming a gate electrode over the active layer, and forming an alignment mark over the substrate. The forming of the alignment mark includes forming a first layer including a first pattern and forming a second layer over the first layer and including concave and convex portions formed along the first pattern. The first insulating layer is interposed between the first and second layers.

Abstract: An organic light-emitting diode display is disclosed. In one aspect, the display includes a substrate and a plurality of pixels formed over the substrate, each pixel including a first region from which light is emitted and a second region through which external light is transmitted. The display also includes a plurality of pixel circuit units each formed in the first region and including at least one thin-film transistor, an inorganic insulating film formed in the second region, a transparent conductive film formed over at least a portion of the inorganic insulating film, and an organic insulating film covering the pixel circuit units and at least a portion of the transparent conductive film. The display further includes a plurality of first electrodes formed over the organic insulating film and in the first regions of the pixels.

Abstract: A supple, globally flexible, composite protective material having guard plates on a substrate with a clearly visible pattern. The substrate is flexible and has a surface with a colored pattern including two or more colors. The guard plates are small, non-overlapping, printed resin material members having major and minor dimensions and are arranged in a predetermined pattern over a substantial portion of the surface of the substrate. In one embodiment of the invention the guard plates are transparent or translucent to visible light so that the colored pattern on the surface of the substrate is visible. In another embodiment the colors of the guard plates blend in with the colored pattern of the substrate.

Abstract: A method for evaluating a structural strength of cancellous bone and a computer readable media incorporating a program for implementing the method therein. The method includes the steps of acquiring an x-ray image and defining a region of interest on the acquired x-ray image; extracting a bone trabecular pattern in the defined region of interest; and setting an index of the structural strength of the cancellous bone using an area density of the extracted bone trabecular pattern.
