Abstract
A driving circuit for a touch screen, an in-cell touch screen and a display apparatus. A timing controller of the driving circuit controls a power supply circuit to output a clock signal with a first amplitude to an (N+1−n)-stage to an N-stage shift registers (SR(n)) in a first time period at a display stage, and controls the power supply circuit to output a clock signal with a second amplitude to each stage of shift register (SR(n)) in a second time period at the display stage; and then levels of scanning signals output by the (N+1−n)-stage to the N-stage shift registers (SR(n)) are higher than levels of scanning signals output by other stages of shift registers (SR(n)).
