Abstract: Embodiments of the invention provide a recording device, which comprises a recording unit, a management unit and a storage unit, wherein the management unit is arranged to generate an identification code and write the identification code into the storage unit, the storage unit is arranged to store the identification code, and the recording unit is arranged to read the identification code from the storage unit and record the identification code into TFT display module. The recording device can record the unique code for each TFT display module to uniquely distinguish different TFT display modules, thereby facilitating tracking and adjustment of parameters, such as color and the like, of an installed TFT display terminal. On the other hand, the recording device can simplify a large amount of complex marking work, and guarantee that the TFT display modules would not be identified mistakenly while saving manpower and material resources.

Abstract: The present disclosure provides a test device and a test method using the test device. The test device includes a first fastener structure for fastening a to-be-tested substrate with first touch lines, a second fastener structure for fastening a test match panel with second touch lines, and the first touch lines and the second touch lines forming a touch module, a third fastener structure for supporting a change-over flexible printed circuit board, a signal input structure for electrically connecting to one of a circuit board in the test match panel and the first touch lines through the change-over flexible printed circuit board, and inputting trigger data signals, a sensing signal capture structure for capturing touch sensing signals in the first touch line or the second touch lines.

Abstract: The present invention provides a detecting circuit, a detecting method and a display device, and the detecting circuit includes data signal input buses, switching units and control units, wherein the data signal input buses are used to provide data signals to the data lines and a predetermined number of data lines corresponding to a central region of the display panel constitute a first data line group; the switching units are arranged between the data lines and corresponding data signal input buses, all of which are divided into two switching unit groups, and all switching units in correspondence with the data lines in the first data line group constitute a first switching unit group; and the control units are used to control all switching units of corresponding switching unit groups to be turned on or turned off simultaneously.
