Title:
COMPLEX INPUT-TYPE TOUCH PANEL
Document Type and Number:
WIPO Patent Application WO/2010/107271
Kind Code:
A2
Abstract:
The present invention relates to a complex input-type touch panel configured to detect: a soft touch input in which a body or a touch device with a conductive property similar to the body lightly touches or approaches a single touch panel; and a pressure-type touch input in which a 2nd substrate is pressed by a touch device such as a touch pen or a nonconductor. The present invention comprises: a 1st substrate (30) and a 2nd substrate (60) which are made of optical transparent materials and are distanced from each other by multiple spacers (25); 1st capacitive signal lines (32), 2nd capacitive signal lines (34), and 3rd capacitive signal lines (36); a capacitive touch cell (31) having a 3-terminal type capacitive switching device (40) and a touch pad (50); multiple 1st resistive signal lines (42) and 2nd resistive signal lines (44); a resistive touch cell (70) having a 1st conductive pad (46) and a 2nd conductive pad (48); and a touch position detector (80) which applies position detecting signals to each of the 1st capacitive signal lines (32) and the 1st resistive signal lines (42).
