An array substrate and manufacturing method thereof, a display device are provided. The array substrate includes a display region and a non-display region; the non-display region includes a first laminated structure and a second laminated structure that are separately disposed on a base substrate, a gap between the first laminated structure and the second laminated structure constitutes a connecting hole; the first laminated structure includes a first via hole provided for exposing a first metal layer, the second laminated structure includes a second via hole provided for exposing a second metal layer, the first via hole and the second via hole are connected to a connecting hole via breaches on corresponding walls, and the first metal layer and the second metal are electrically connected with a conductive film.

Array substrate and manufacturing method thereof, display device

An array substrate, comprising: a substrate; a metal pattern formed on the substrate; an insulation layer formed on the metal pattern and formed with a via therein; and a transparent conductive pattern formed on the insulation layer and electrically connected to the metal pattern through the via, wherein the via has a cross section exhibiting an irregular geometry shape having a curved side edge.

Array substrate and method for producing the same, display

The disclosed technology provides a detection apparatus and its operating method. The disclosed technology provides a detection apparatus, comprising: a test chamber, an exchange chamber, and a communicating mechanism, which is provided between the test chamber and the exchange chamber and capable of rendering the test chamber and the exchange chamber separated from or communicated with each other; wherein transmission devices are positioned within the test chamber and the exchange chamber, respectively, and the transmission devices are adapted to convey a probe frame from the test chamber to the exchange chamber or from the exchange chamber to the test chamber.

Detection apparatus and operating method

The present invention relates to a substrate testing circuit comprising a testing bus and a testing signal terminal connected to the testing bus, a signal line to be tested in the substrate being connected to the testing bus via a signal connecting terminal, wherein a plurality of signal access terminals are provided on the testing bus; one testing branch is connected between each the signal access terminal and the testing signal terminal; and resistance values of the testing branches are the same. By means of the present invention, since a plurality of signal access terminals are introduced and the testing branches with the same resistance are added so that input resistances and impedances of testing signals across the display screen are substantially identical without making changes to process flow and device hardware structure, input resistances and impedances of respective signal lines are well averaged, thereby no obvious regional attenuation occurs in the testing signals within the pixel area to be tested irrespective of limitation in size of panel, so as to realize tests for panels with greater sizes.
