Abstract
A complex resistance type coordinate input device includes an upper conductive structural layer, a lower conductive structural layer, and an intermediate conductive structural layer being disposed between the upper conductive structural layer and the lower conductive structural layer. The upper conductive structural layer provides an upper conductive thin layer, the lower conductive structural layer provides a lower conductive thin layer, and the intermediate conductive structural layer provides the first intermediate conductive thin layer facing the upper conductive thin layer and the second side of the intermediate conductive structural layer to form a digit-resistance type touch pad structure, and the second intermediate conductive thin layer facing the lower conductive thin layer to form an analog-resistance type touch pad structure.
