Abstract

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.

Description

technical field [0001] The invention relates to the technical field of flat panel display, in particular to an integrated panel and a testing method. Background technique [0002] With the rapid development of electronic technology and intelligent technology, it is becoming a trend to integrate various functions into the same electronic device. By using integrated sensors to detect external signals and perform human-computer interaction operations, human wishes can be quickly and directly converted into signals recognizable by equipment, and corresponding feedback can be made. In high-tech fields such as artificial intelligence skin, display touch panel, and weak force detection, it is of great significance to quickly and accurately identify the magnitude of force. [0003] At present, the application of force detection is detected by various voltage control methods such as piezoresistive, piezocapacitive, and piezoelectric. The voltage-controlled sensor has higher detectio...
