[0078] When preparing the conductive layer 221, the metal conductive layer 221 can be formed on the third transparent medium layer by a physical vapor deposition (PVD) process, a chemical vapor deposition (CVD) process, a sputtering process, an atomic layer deposition (ALD) process, etc. 222 surface. When there are two or more metals in the conductive layer 221 , it can be prepared by co-deposition, and the co-deposition is realized by PVD sputtering, such as magnetron sputtering, thermal evaporation, electron beam evaporation and the like.

[0079] For the transparent electrode provided in this embodiment, the wavelength of the transmitted electromagnetic spectrum is preferably 380 nm to 780 nm, and the light transmittance ranges from 40% to 90%. For example, the transmittance may be greater than or equal to 40%, or greater than or equal to 50%, or greater than or equal to 55%, for a selected target wavelength or wavelength range of the electromagnetic spectrum (which may be ...

Abstract

The invention relates to the technical field of electrodes, and provides a transparent electrode assembly, a device and a preparation method of the transparent electrode assembly. The patterned transparent electrode is arranged on the surface of the substrate layer; the shadow eliminating layer is made of a photochromic material and comprises a first shadow eliminating area and a second shadow eliminating area, the first shadow eliminating area is arranged on the surface, opposite to the substrate layer, of the transparent electrode, and the second shadow eliminating area is arranged between the etched transparent electrodes and located on the surface of the substrate layer. The preparation method comprises the following steps: arranging a shadow eliminating layer on the surface of a patterned transparent electrode, wherein the shadow eliminating layer is made of a photochromic material; and irradiating one side, back to the shadow elimination layer, of the transparent electrode by adopting a spectrum of a preset wave band, so that the shadow elimination layer changes color under the action of the spectrum, and a first shadow elimination area and a second shadow elimination area are formed to obtain the transparent electrode assembly. According to the invention, the transmittance of the transparent electrode assembly to the spectrum is the same, so that the purpose of shadow elimination is achieved.

Description

technical field [0001] The present invention relates to the technical field of electrodes, and more specifically, relates to a transparent electrode assembly, a device and a method for preparing a transparent electrode assembly. Background technique [0002] With the rapid development of the display technology, the development of the display is also changing rapidly. For example, in the structure of the touch screen, the surface of the display screen is also provided with a conductive structure to realize the touch function. These structures will absorb or reflect light more or less, which will affect the luminous efficiency and even the display effect, so conductive materials with high transmittance must be used. For example, a tin-doped indium oxide film (Indium tin oxide, ITO) is widely used in commercial applications as a representative metal oxide film. [0003] However, in the process of making the touch screen, the electrode structure needs to be patterned to meet th...
