The present disclosure provides a shadow elimination detection method for a touch substrate, a touch substrate manufacturing method, a touch substrate, and a touch device. The shadow elimination detection method for a touch substrate includes detecting a difference in light reflectance between test blocks with different structures located in an area outside a touch area of the touch substrate using a detection device, and determining a shadow elimination effect of the touch substrate according to the difference, wherein each of the test blocks with different structures includes a structure corresponding to a respective structure in different structures in the touch area.
說明書
This patent application is a National Stage Entry of PCT/CN2017/093647 filed on Jul. 20, 2017, which claims the benefit and priority of Chinese Patent Application No. 201610868054.9 filed on Sep. 30, 2016, the disclosures of which are incorporated herein by reference in their entirety as part of the present application.
Embodiments of the present disclosure relate to the field of touch control technology, and in particular, to a shadow elimination detection method for a touch substrate, a touch substrate manufacturing method, a touch substrate, and a touch device.
At present, the capacitive touch screen has become a very popular electronic product, and OGS (One Glass Solution) has become a mainstream technical solution thereof. OGS refers to the technology of directly forming an indium tin oxide (ITO) conductive film and sensors on a protective glass of a touch screen. There are channel patterns formed by ITO in the visible area of the OGS touch screen. The visibility of the ITO channel patterns (referred to as the shadow elimination level in technical terms) is related to the user experience. Therefore, in the manufacturing process of the touch screen, its shadow level needs to be tested.
