Abstract: The present invention discloses a touch point detection method, device, a touch driving circuit and a touch panel. After determining a to-be-determined touch point among touch detection points of a touch panel, it is determined 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; and after it is determined that the to-be-determined touch point is influenced by the noise of the display driving circuit, it is determined whether the to-be-determined touch point is a touch point according to the second noise value and a preset first threshold value; the second noise value is the noise value of the touch driving circuit when the display driving circuit is turned on. Because it is determined whether the to-be-determined touch point is influenced by the noise of the display driving circuit before determining whether it is a touch point, it is possible to effectively identify interference of noise on the touch signals, improve signal-to-noise ratio of touch signals, and ensure accuracy of touch determining operation.
