Abstract
An electromagnetic-type touch display apparatus is disclosed. The apparatus comprises: a first substrate; a second substrate; a first conductive layer formed on the first substrate comprising first electromagnetic induction coils forming loops extending in a first direction; and a second conductive layer formed between the first and second substrates comprising second electromagnetic induction coils forming loops extending in a second direction perpendicular to the first direction. Each of the substrates comprises a display region and a non-display region, and the first and second electromagnetic induction coils are used to determine a touch position, wherein, at least one of the first conductive layer and the second conductive layer is also configured as at least one film layer of the first substrate or the second substrate, which forms a pattern required by the first or second electromagnetic induction coils and transmits a sensing signal.
