An embodiment of the present invention provides a manufacturing method of an array substrate comprising forming a gate detecting pattern on the array substrate with gate lines and common electrode lines formed thereon, the gate detecting pattern being arranged on one side of a pixel region of the array substrate and used to connect all the common electrode lines for pixel units; and performing a short circuit or a open circuit detection, wherein if the difference between a signal received by a receiving terminal for a gate line and a signal transmitted from a transmitting terminal for the gate line is larger than a predetermined detection threshold value, it is determined that short circuit between the gate line and a common electrode line or open circuit in the gate line occurs.

Manufacturing method of array substrate

A coal gasification process is provided based on the grading conversion of carbon hydrogen components of coal, wherein the coal gasification process comprises a carbonization process, a carbon monoxide-producing process and a shift reaction process. By blending the coke-oven gas, carbon monoxide and hydrogen produced in the above processes in different ratios, coal gasification syngases with various carbon hydrogen ratios can be obtained. Further, the coal gasification process does not need pure oxygen to take part in the reactions, and has several advantages, such as high gasification efficiency, low equipment investment costs, less limitation on the types of coal and flexible adjustment of the gasification products.
