The invention discloses a production method of an industrial control LCD display panel. A substrate is cut into a required panel size, four sides are polished after cutting, a plurality of substrateswith the same size are obtained, the SMT workpiece beating is carried out on the cut substrates, a conductive strip is formed on an upper-layer substrate, a lower substrate is attached to a surface, provided with the conductive strip, of the upper-layer substrate, a TFT layer is manufactured on the substrates, then a passivation layer is prepared on the TFT layer, a color resistance layer is formed on the passivation layer, a PFA protection layer is formed on the color resistance layer, a pixel electrode layer is prepared on a surface of the PFA protection layer, then the substrates are subjected to spraying and excited state ultraviolet irradiation, a point screen test and an ATE electrical performance test are performed on the substrates, the frame packaging is performed on the substrates, and a golden finger is welded. The production method has the advantages of simple technological process and convenient realization of mass production, the manufacturing cost of a single display panel is reduced, the golden finger is welded after the electrical performance test, a panel is not easy to scrap due to problems such as short circuit and the like, and meanwhile, the problem that the panel is fragile is avoided by packaging.
