ABSTRACT:
A probe device that includes a plurality of actuators respectively associated with a plurality of probe units. The probe device is adaptive to various display panels each having electrode terminals arranged at a particular pitch, without resorting to additional probe units. The probe device is therefore feasible for general-purpose applications and low in operation cost. In addition, the probe device allows electrode terminals and probes to be accurately aligned with each other. This enhances accurate testing, surely excludes defective products, and frees the subsequent steps from wasteful cost. A method of positioning the probes is also disclosed.
