This operator is only applied to coverage, and partly to attributes. In coverage, outcome shows those registers (polygons) which no contains the indicated coverage.

With attributes the operation carried out is “NOT LIKE” or no contain. This operation checks if the attribute field doesn’t contain the selected value.

If you don’t select coverage or an attribute, but “≠” operator is selected, it’s going to carry out an operation “IS NOT NULL”. Therefore, only are going to be selected the registers which don’t contains this null value (coverage or attribute, depending on which one are no selected).
