Embodiment Construction

[0022] In the following embodiments, the laser processing method is adopted without using chemicals and avoiding pollution to the environment.

[0023] combined reference figure 1 , a processing method for an ITO film, comprising the steps of: placing a substrate 20 with an ITO film 10 on a processing table 30, the ITO film 10 facing the table 30 and setting a gap 40 between the ITO film 10 and the table 30; The side where the substrate 20 is located emits a laser 50 to process the ITO film 10 .

[0024] The substrate 20 may be glass, polyethylene terephthalate (polyethylene terephthalate, PET for short) and the like.

[0025] A gap 40 is provided between the ITO film 10 and the table top 30 , for example, the substrate 20 is padded with a jig to keep a certain distance between the table top 30 and the ITO film 10 , which is convenient for dust suction in the gap during laser processing. For example, a through hole is provided on the table top 30 so that the through hole com...

Abstract

The invention relates to a method for processing ITO membrane, comprising the followings steps: a substrate attached with the ITO membrane is placed on a processing table, the ITO membrane faces the processing table and clearance is arranged between the ITO membrane and the processing table; laser is transmitted from one side where the substrate is located to process the ITO membrane. As laser processing is adopted, no chemical medicine is needed, thus avoiding polluting the environment; in addition, the purpose of rapid preparation of the membrane can be realized so long as the ITO membrane is processed by the laser technology; furthermore, the invention also provides an electric device containing transparent electrodes prepared by the method for processing the ITO membrane.

Description

【Technical field】 [0001] The invention relates to the field of processing technology of transparent conductive films, in particular to a processing method of an ITO film and an electronic device made by using the processing method of the ITO film. 【Background technique】 [0002] Tin-doped indium oxide (Indium Tin Oxide, referred to as ITO) material is an n-type semiconductor material, due to its high electrical conductivity, high visible light transmittance, high mechanical hardness and chemical stability, it is a liquid crystal display ( LCD), plasma display (PDP), electroluminescent display (EL / OLED), touch screen (Touch Panel), solar cells and the most commonly used materials for transparent electrodes of other electronic instruments. According to different applications, ITO films need to be processed into different shapes. [0003] Traditional ITO film processing generally uses masks and chemicals for etching. There are some problems in this processing process: [0004...
