Claim Text:
1. A touch point detection method comprising: determining a to-be-determined touch point among touch detection points of a touch panel; determining whether the to-be-determined touch point is influenced by noise of a display driving circuit according to a touch signal, a first noise value and a second noise value of touch detection points in a line where the to-be-determined touch point is located; wherein the first noise value is a noise value of the touch driving circuit when the display driving circuit is not turned on, and the second noise value is a noise value of the touch driving circuit when the display driving circuit is turned on; upon determining that the to-be-determined touch point is influenced by the noise of the display driving circuit, determining whether the to-be-determined touch point is a touch point according to the second noise value and a first threshold value; the first threshold value being greater than the first noise value and smaller than the second noise value.
