Technical Field

[0001] The utility model relates to the technical field of ITO transparent conductive films, in particular to an ITO transparent conductive film provided with an anti-bending layer. Background Art

[0002] Several commonly used types of touchscreens, such as resistive touchscreens, surface capacitive touchscreens, and inductive capacitive touchscreens, all require the use of transparent conductive films as electrode materials. Transparent conductive films are generally defined as being transparent in the visible light range and having low resistivity. Commonly used transparent conductive films include ITO films, AZO films, and aluminum oxide. Among conventional transparent conductive films, ITO (indium tin oxide) films are the most common and offer the best performance. However, existing ITO transparent conductive films have poor bending properties and are prone to cracking or even breaking when bent, impacting their lifespan. Therefore, we propose an ITO transparent conductive film with an anti-bending layer. Utility Model Content
