Embodiment 1

[0028] Such as figure 1 As shown, it represents a manufacturing method of an OLED product provided by the present invention. The manufacturing method of the OLED product specifically includes the following steps:

[0029] Step 1, providing an ITO substrate; specifically, the step 1 may include: step 1.1, providing a transparent substrate; step 1.2, making a SiO2 layer on the transparent substrate; step 1.2, plating the second SiO2 layer on the SiO2 layer One ITO layer. Wherein, the transparent substrate is preferably a glass substrate, and its surface is polished before making the SiO2 layer, and the thickness of the SiO2 layer is 200 to 300 Å; the manufacturing method of the first ITO layer is magnetron sputtering, The deposition temperature is between 200-280°C, and the thickness can be 800-2200Å. After the first ITO layer is manufactured, the surface needs to be soft-polished to control its surface roughness Ra<10Å.

Abstract

The invention provides an OLED product and a production method thereof. The production method comprises the following steps: 1, providing an ITO substrate; 2, etching a first ITO layer on the ITO substrate to form an ITO anode layer; 3, producing an Mo alloy layer on the ITO anode layer, and producing a second ITO layer on the other surface of the ITO substrate; 4, etching the second ITO layer toform a first ITO touch layer; 5, producing and etching a first Mo / Al / Mo pattern layer on the first ITO touch layer; 6, producing a hard protective layer on the first ITO touch layer and the first Mo / Al / Mo pattern layer; 7, removing the Mo alloy layer; 8, producing and etching a second Mo / Al / Mo pattern layer on the ITO anode layer; 9: producing an OLED functional layer and a metal cathode layer. Bythe production method, the problem of poor compatibility between the existing technical scheme of adding auxiliary metal in the process of producing an OLED product by an ON CELL technology and an Moalloy protection scheme can be solved, and the product quality and the production efficiency can be effectively improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for manufacturing an OLED product and the OLED product. Background technique [0002] ON CELL technology is one of the best solutions for integrated touch function of OLED products. This technology sets the ITO touch layer on the light-emitting surface of OLED products. When etching the touch pattern of the ITO touch layer, it is necessary to first place the touch pattern on the back of the substrate. The ITO anode layer is protected, and the commonly used protection method is to silk screen or paste a protective film on the ITO anode layer. Although this type of protection method is relatively simple in equipment and process, it is prone to problems such as residual glue and ITO anode layer being crushed, and the protective film needs to be manually torn off after the ITO touch layer is etched, which is not conducive to the automation and high efficiency of the process...
