A PRESSURE SENSING DEVICE USING BOTTOM-LAYER PRESSURE SENSITIVE CHANNEL ON THE 2-LAYER STRUCTURE TOUCH SCREEN PANEL

摘要

The present invention relates to a pressure sensing device using a channel for sensing lower layer pressure in a two-layer structure touch screen panel. The device comprises: a touch screen panel touch unit (110) in which a plurality of Tx-electrode patterns (113) are formed; and a touch screen panel controller (120) electrically connected to the touch screen panel touch unit (110). Therefore, the device reduces manufacturing costs of the touch screen panel to improve productivity.
