摘要： A flat panel detector includes a base substrate, a sensing electrode and a bias electrode over the base substrate, and an insulating layer over the sensing electrode and the bias electrode at a side distal from the substrate. A difference between thicknesses of regions of the insulating layer corresponding to the sensing electrode and the bias electrode respectively is not greater than a preset threshold. When a sufficiently high voltage is applied to the insulating layer and turned on, because the thickness thereof is relatively uniform, a dark current generated by the sensing electrode and the bias electrode under the insulating layer is relatively uniform, thereby improving detection accuracy of the flat panel detector.

摘要： An array substrate and a fabrication method thereof, and a display device are provided. The array substrate comprises: a pattern of an organic light-emitting layer (11); a pattern of an active layer (4a) located in a thin film transistor region and a pattern of an absorbing layer (4b) located in an open region, which are arranged in a same layer, wherein, the pattern of the absorbing layer (4b) is located in a light outgoing direction of the pattern of the organic light-emitting layer (11), and is made of a transparent material having an ultraviolet absorbing function. In this way, the pattern of the absorbing layer located in the open region can absorb ultraviolet light from outgoing light, so that damage to eyes caused by the outgoing light can be reduced; and the pattern of the active layer and the pattern of the absorbing layer are arranged in a same layer, which, as compared with a manner of separately arranging a layer of an ultraviolet absorbing layer in the array substrate, can reduce a thickness of the array substrate, which is conducive to lighting and thinning a display device.
