S108: if the difference is less than the difference of the flicker value, finding the optimal common electrode voltage and an optimal flicker value;

S109: after finding the optimal common electrode voltage, confirming whether the optimal common electrode voltage is within the range;

S110: if within the range, shipping out goods normally;

S111: If not within the range, the steps S107 to S109 are repeated until the optimum common electrode voltage is within the range.

In the panel inspection method provided by the embodiment of the present invention, the optical probe set includes at least two optical probes in S105, and the number of the flicker values is equal to the number of the optical probes.

In the panel inspection method provided by the embodiment of the present invention, the host performs subtraction operations in pairs for all the read flicker values in S105, to get the largest difference.

In the panel inspection method provided by the embodiment of the present invention, first find the optimal flicker value in S108, and after finding the optimal flicker value, the optimal common electrode voltage corresponding to the optimal flicker value is found.

In the panel inspection method provided by the embodiment of the present invention, the method of finding the optimal flicker value is to obtain a minimum flicker value by comparison in S108, which is the optimal flicker value.
