A touch input device capable of detecting a touch position and touch pressure may be provided that includes: a display panel; a touch sensor including a touch electrode which is used to detect the touch position; and a pressure sensor including a pressure electrode which is used to detect the touch pressure. A harmonic frequency and a frequency of a horizontal synchronization signal, which is used to drive the display panel, do not exist within a first gap from a touch pressure sensing frequency which is used to drive the pressure sensor. The first gap may be 5 kHz.
