The present invention concerns the field of safe disposal or recycling of devices which include flat panel displays (FPDs) such as televisions, public information screens and signs, advertising panels, computer monitors and lap-tops, tablets and computers with integrated flat panel displays. The invention provides an apparatus for the disassembly of flat panel display units (FPDs) which each comprise a display screen provided on the front face of the FPD and a housing which accommodates the screen and associated electronic circuitry, the apparatus comprising: (i) a cutting station for receiving an end-of-life FPD, the cutting station being configured and arranged to make cuts into the FPD along cutting paths which permit detachment of the entire display screen, or a cut-out sub-unit of the display screen, from the FPD, (ii) an FPD characterisation station provided in advance of, or at, the cutting station, the characterisation station being adapted to measure and/or log one or more characterising parameters or identifiers of the FPD in advance of the cutting step, (iii) a data processing system in data communication with the FPD characterisation station, the data processing system being adapted to receive and one or more of said parameters or identifiers, and derive therefrom an appropriate protocol for cutting the FPD display screen, and provide instructions in accordance with the protocol which are sent back to the cutting station so as to control the cuts. An FPD database may be associated with the data processing system, the FPD database being pre-loaded with cutting path instructions for a range of known FPDs.
