Abstract
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.
