Abstract
A driving circuit for touch screen, a touch screen, and an electronic terminal are disclosure. The driving circuit for touch screen comprises: a control circuit, used for generating and outputting a scanning signal and a data selection signal according to a position of an electrode to be driven; and a data selection circuit, an input end thereof being connected with said control circuit, output ends thereof each being connected with a corresponding scanning end of the touch screen, wherein the data selection circuit is configured to turn on or turn off a connection between an input end thereof and an output end corresponding to the electrode to be driven according to said data selection signal. In the driving circuit, the influence on the following detection of the touch points generated by the attenuation of the scanning signal during transmission process can be reduced effectively, so that the reliability and accuracy of the detection result can be ensured.
