摘要：
A touch panel comprises light sensing circuits configured to generate light sensing data, scan lines, a scan driving unit configured to sequentially apply scan pulses to the light sensing circuits via the scan lines, data lines, a data receiving unit configured to receive the light sensing data transmitted via the data lines in a first/second data receiving state, and generate touch data including first and second touch data, and a location calculation unit configured to determine a touch location using the touch data. In the first/second data receiving state, two neighboring data lines in each first/second combination are electrically coupled to each other, and light sensing data from the data lines in each first/second combination are combined so as to generate a first/second data. The first/second touch data includes the first/second data from each of the first/second combinations. The second combinations are different from the first combinations.
