One aspect of the present disclosure provides a touch panel shadow elimination detection method which includes detecting a difference in light reflectance between test blocks with different structures located in an area outside a touch control area of a 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.

Another aspect of the present disclosure provides a method for manufacturing a touch substrate which includes forming test blocks with different structures in an area outside a touch area of a touch substrate in a manufacturing process of the touch substrate, wherein each of the test blocks with different structures includes a structure corresponding to a respective structure in different structures in the touch area.

Still another aspect of the present disclosure provides a touch substrate including test blocks with different structures located in an area outside a touch area thereof, wherein each of the test blocks with different structures includes a structure corresponding to a respective structure in different structures in the touch area.

Still another aspect of the present disclosure provides a touch device which includes the touch substrate according to any embodiment of the present disclosure.
