Title:
FORCE-TOUCH PANEL AND DISPLAY APPARATUS INCLUDING SAME
Document Type and Number:
WIPO Patent Application WO/2019/231103
Kind Code:
A1
Abstract:
A force-touch panel according to the present invention is characterized by comprising: a first substrate; a second substrate; an elastic resistor member disposed on the second substrate-facing surface of the first substrate; an electrode structure formed on the first substrate-facing surface of the second substrate; and a spacer for spacing apart the first substrate and the second substrate from each other, wherein the thickness of the spacer is less than a value of the sum of the thickness of the elastic resistor member and the thickness of the electrode structure. Through the present invention, reliable force-touch sensing can be made possible even when there is an air-gap formed between the force-touch panel and a middle-frame in a display apparatus. In addition, the air-gap can be minimized to increase the durability inside the force-touch panel, and an elastic member can be brought into contact with the electrode structure to electrically connect a VCC electrode and a GND electrode that are included in the electrode structure to allow an initial resistance value in an IC to be checked and thereby enable continuous tracking.
