The present invention provides a touch screen display apparatus including a touch structure. The touch structure includes multiple driving lines arranged in a column direction, multiple sensing lines arranged in a row direction, a preamplifier, a frequency outputter, a first shift register, and a second shift register. The first shift register is arranged between the driving lines and the frequency outputter, and the second shift register is arranged at output ends of the sensing lines. Each driving line outputs a driving signal and each sensing line outputs a sensing signal for the preamplifier. Accordingly, a single preamplifier may be used. |
