摘要:
A touch-sensored display device 20 according to the present invention includes: a counter substrate 6 disposed on a viewer side of an active matrix substrate 8 via a display medium layer 4, the counter substrate 6 having a counter electrode 5 which opposes pixel electrodes; a display panel driving circuit 14 for supplying to the counter electrode 5 a common voltage which undergoes periodic inversion in polarity; a transparent conductive film 7 for position detection placed so as to oppose the counter electrode 5 via the counter substrate 6; a strobe signal generation circuit 32 for generating a strobe signal which is in synchronization with a polarity inversion period of the common voltage, and a noise-cut current signal generation circuit 30 for generating a noise-cut current signal which is obtained by eliminating based on the strobe signal a predetermined portion from a current flowing from a terminal connected to the transparent conductive film 7 for position detection.
