A person shall be entitled to a patent unless –
(a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.

As to claim 16, Oke shows that the voltage compensation circuit includes: an operational amplifier 701 including an inverting input terminal connected to the input resistor (Fig. 14 and para. 100), a non-inverting input terminal configured to receive the DC voltage (Fig. 14 and para. 99), and an output terminal connected to the sensor driver (Figs. 6 and 14 and paras. 107 – 110); and a feedback resistor connected between the inverting input terminal and the output terminal of the operational amplifier (Fig. 14).
Allowable Subject Matter
Claims 3, 4, 6 – 8, 11, 12, 15, 17 and 18 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
Specifically, claim 3 recites a plurality of switching elements connected to the sensor lines, wherein the switching elements are configured to be turned on during the second period to connect the sensor lines to each other and to connect the sensor lines to the input resistor.
The prior art does not show this configuration; therefore this claim contains allowable subject matter.
Claim 4 contains allowable subject matter at least by virtue of its dependence on claim 3.
Also, claim 6 recites that the voltage compensation circuit includes: a transistor configured to be turned on to supply a DC voltage to the input resistor during the first period and to be turned off during the second period in response to a touch enable signal.
The prior art does not show this configuration; therefore this claim contains allowable subject matter.
Claim 7 contains allowable subject matter at least by virtue of its dependence on claim 6.
Also, claims 8 and 18 recite that the voltage compensation circuit includes: a multiplexer configured to supply the DC voltage to the input resistor during the first period and to connect the sensor lines to the input resistor during the second period in response to a touch enable signal.
The prior art does not show this configuration; therefore these claims contain allowable subject matter.
Also, claim 11 recites that the inverting amplifier includes: an input resistor electrically connected to the sensor lines; an operational amplifier including an inverting input terminal connected to the input resistor, a non-inverting input terminal configured to receive a DC voltage, and an output terminal; a first transistor and a first feedback resistor connected in series between the output terminal and the inverting input terminal of the operational amplifier; and a second transistor and a second feedback resistor connected in series between the output terminal and the inverting input terminal of the operational amplifier.
The prior art does not show this configuration; therefore this claim contains allowable subject matter.
Claim 12 contains allowable subject matter at least by virtue of its dependence on claim 11.
Also, claim 15 recites that the display panel includes: a plurality of switching elements connected to the sensor lines, and wherein the switching elements are configured to be turned on during the second period to connect the sensor lines to each other and to connect the sensor lines to the input resistor, and are configured to be turned off to electrically disconnect the sensor lines from each other and to electrically disconnect the sensor lines from the input resistor during the first period.
The prior art does not show this configuration; therefore this claim contains allowable subject matter.
Also, claim 17 recites that the voltage compensation circuit includes: a transistor configured to be turned on to supply the DC voltage to the input resistor during the first period and to be turned off during the second period in response to a touch enable signal.
The prior art does not show this configuration; therefore this claim contains allowable subject matter.
