For example, in the exemplary embodiment of the present invention illustrated in FIG. 1, the lever push unit 300 is configured as one to inspect the AMOLED panel 10 sequentially arranged for each channel, but the present invention is not limited thereto, and the lever push unit 300 is not limited thereto. ) May be configured in plural to perform dual inspection.

For example, assuming a ten-channel structure, the first lever push unit 300-1 examines the first to fifth channels, and at the same time, the second lever push unit 300-2 performs the sixth to tenth channels. There is an advantage that can reduce the inspection time by half.

In addition, in the embodiment of the present invention illustrated in FIG. 1, the lever push unit 300 has been described as capable of operating only one lever 250, but is not limited thereto. The lever push unit 300 may be moved in a horizontal direction. In the form of an extended push bar, the plurality of levers 250 may be operated simultaneously with the lowering.

At this time, since the lever push unit 300 can operate two or more levers 250 simultaneously according to the length extending in the horizontal direction, it is possible to simultaneously inspect a large amount of AMOLED panel and to shorten the inspection time. have.

The embodiments of the present invention are not limited to the above-described apparatuses and / or methods, but may be implemented through a program for realizing functions corresponding to the configuration of the embodiment of the present invention, a recording medium on which the program is recorded And such an embodiment can be easily implemented by those skilled in the art from the description of the embodiments described above.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, It belongs to the scope of right.
