ABSTRACT:
A flat-panel display device having test architecture is disclosed for disposing shorting bars without sacrificing wiring-on-array bus layout area of the outer-lead-bonding region. The flat-panel display device essentially includes a substrate having a plurality of driving integrated-circuit (IC) mounting areas, a plurality of signal lines and transmission lines disposed on the substrate, and a plurality of shorting bars disposed on the driving IC mounting areas. Each shorting bar is coupled to a corresponding signal line and a corresponding transmission line. Furthermore, in order to take out the laser-cutting process in the fabrication of the flat-panel display device for saving production cost, each driving IC mounting area is further disposed with a plurality of transistors for controlling the signal connections between the shorting bars and the signal lines, and also for controlling the signal connections between the shorting bars and the transmission lines.
