Abstract: A detection device of a GOA circuit of a display panel includes a signal supply unit for supplying a test signal to the GOA circuit; an acquisition unit for determining whether each of the GOA units in the GOA unit group of the GOA circuit has an output signal, if there is an output signal, acquiring the output signal of each of the GOA units in the GOA unit group; wherein part of the GOA units in the GOA circuit constitute the GOA unit group, the GOA unit group at least includes an initial GOA unit and a distal GOA unit of the GOA circuit; a processing unit for determining whether the GOA circuit is abnormal based on the acquired output signal of each of the GOA units in the GOA unit group.

Abstract: A display module detection device is disclosed. The display module detection device includes a storage module, in which configuration parameters of multiple types of display modules are pre-stored for determining a configuration parameter to be outputted by the storage module based on a type of a display module to be detected, and a test system module being communicatively connected with the storage module and configured for determining an output parameter of a test signal output interface based on the configuration parameter outputted by the storage module.

Abstract: An aluminum alloy product for manufacturing structural components, made from direct chill casting ingots comprises, based on wt %: Zn 7.5˜8.7, Mg 1.1˜2.3, Cu 0.5˜1.9, Zr 0.03˜0.20, the balance being Al, incidental elements and impurities. The levels of Zn, Mg, Cu, and Zr in the aluminum alloy products satisfy the expressions of (a) 10.5?Zn+Mg+Cu?11.0; (b) 5.3?(Zn/Mg)+Cu?6.0; and (c) (0.24?D/4800)?Zr?(0.24?D/5000). D is the minimum length of a line section connecting any two points on the periphery of the cross section of the ingot and passing through the geometrical center of the cross section. 250 mm?D?1000 mm. The aluminum alloy products have a superior combination of strength and damage tolerance, and exhibit homogeneous and consistent performance on the surface, at various depths under the surface, and in the core of the product. A method of producing the aluminum alloy products is also provided.
