Abstract

The invention provides a preparation method of a zinc-based alloy material, which comprises the following steps: A) in an oxygen atmosphere, carrying out heat treatment deoxidation on a zinc-based alloy in a rough blank container to obtain alloy material powder; the zinc-based alloy comprises 60 to 99 weight percent of zinc and 1 to 40 weight percent of aluminum; the temperature of the heat treatment ranges from 1100 DEG C to 1350 DEG C; the heat treatment time is 60 to 120 minutes; and (B) the alloy material powder is sequentially subjected to cold isostatic pressing and hot isostatic pressing treatment, and the zinc-based alloy material is obtained. The zinc-based alloy formula, the preparation process of the target material and the preparation process of the thin film are improved, the prepared zinc-based alloy target material is free of deformation and cracks, and the high-resistance thin film prepared from the alloy material target material has good anti-static capacity and cannot affect the sensitivity of electronic products. The invention provides a zinc-based alloy material and a preparation method of a high-resistance film and a memory high-resistance film.

Description

technical field [0001] The invention belongs to the technical field of electronic display devices, and in particular relates to a zinc-based alloy material, a preparation method thereof, a high-resistance film and a preparation method thereof. Background technique [0002] At present, most of the mutual capacitive touch screens are external, that is, the touch screen and the display screen are made separately and then attached together. This technology has the disadvantages of high production cost, low light transmittance, and thick module. With the development of science and technology, the embedded touch screen technology has gradually become a new favorite of research and development, which means that the driving electrode lines and the detection electrode lines used to realize the touch function are arranged on the substrate of the display screen. Compared with the external touch display device, the touch display device using the embedded touch screen technology has the...
