The invention relates to a sensor control board, a display device and a control method of the display device. Provided is a sensor control board capable of reducing noise included in an image displayed by a display device. The sensor control board is provided with: a clock generation circuit that generates a clock; and a phase adjustment circuit that adjusts the phase of the clock so that the clock is inverted at each predetermined timing, and outputs a transmission signal to the position detector using the adjusted clock as the transmission signal. The position detector is disposed on an upper layer or a lower layer of a display unit in which a plurality of image elements having a common potential input to one end and an individual potential input to the other end are disposed in a lattice shape, and detects a position indicated on the display unit. 本发明涉及传感器控制板、显示装置及显示装置的控制方法。提供能够降低显示装置显示的图像中包含的噪声的传感器控制板。传感器控制板具备：时钟生成电路，生成时钟；及相位调整电路，对时钟以在每个规定的定时下反转的方式调整相位，将调整后的时钟作为发送信号，对位置检测器输出发送信号，位置检测器配置于呈格子状地配置有多个向一端输入共用电
