Abstract

The invention discloses a conductive glass cleaning method. The conductive glass cleaning method includes spraying an alkaline solution on one side of conductive glass with a conductive film for cleaning; spraying alignment liquid on one side of the conductive glass with the conductive film. According to the conductive glass cleaning method, the conductive film on the conductive glass is cleaned through the alkaline solution, the surface activity of the conductive film can be improved, the contact angle between the alignment liquid sprayed later and the conductive film is reduced, and the alignment liquid can be sufficiently and freely diffused on the conductive film to form a uniformly coated alignment film.

Description

technical field [0001] Embodiments of the present invention relate to a cleaning method for glass, in particular to a cleaning method for conductive glass. Background technique [0002] Conductive glass is a commonly used conductive thin film material and is widely used in the field of conductive thin film technology; among them, indium tin oxide (Indium tin oxide, ITO) conductive glass is the most common conductive glass material. [0003] Usually, conductive glass needs to be laminated with other conductive films to form a device with certain functions. Taking ITO glass as an example, in the process of forming devices, it is often necessary to spray PI alignment liquid on the surface of ITO glass. In order to form a uniform PI alignment liquid on the surface of the ITO glass, it is necessary to clean the surface of the ITO glass to improve the surface activity of the ITO glass. [0004] In the prior art, an ultraviolet cleaning machine and a plasma cleaning machine are o...
