Disclosed is a system and method for processing account registration by identifying account candidates attempting to open an account as abusive. The system includes a plurality of interconnected precast panels. To the gates of the read and reset thin film transistors in each pixel are applied ON and OFF voltages at predetermined timings and these voltages are set to values such that any excessive electric charge produced in the storage period is discharged by way of the thin film reset transistor, not by way of the thin film read transistor, in the same storage period.
