The invention discloses an integrated panel and a testing method. According to the integrated panel, a pressure control unit, a constant reference unit and a TFT signal detection and amplification unit are integrated and designed into a pressure sensing and detecting module; weak electrical parameter variation of the stressed pressure control unit causes variation of input voltage and current of the TFT signal detection and amplification unit; the output current of the TFT signal detection and amplification unit is further adjusted to a magnitude order variation range; signals are rapidly amplified and collected by using the characteristics of operation zones of thin-film transistor (TFT) devices; the sensitivity and the accuracy of pressure detection can be improved; the integrated panelis especially applicable to real-time detection of weak force.
