Abstract

Disclosed are a contact error testing apparatus and method for TCP (tape carrier package) output pins of a flat panel display, and an error testing system for the flat panel display. The contact error testing apparatus indirectly determines whether the connection state between the TCP output pins and the bonding pads connected to the electrodes of the flat panel display is open, short, or normal without turning on the flat panel display, by connecting the reference resistor (RREF) between one selected from the plurality of inverter circuits contained in the TCPs and the input power source (Vpp) and measuring the variation of voltages across the reference resistor (RREF).
