摘要： Disclosed are display panel test device and method. The device comprises: a color analyser including a host and a measuring probe, wherein the measuring probe can obtain optical information of a positional point of a light emitting surface of display panel, the positional point being a point to which the measuring probe is aligned on the light emitting surface, and the host can determine optical characteristics of the positional point according to the optical information; and a position determination component, configured to determine a positional identifier of the positional point on the light emitting surface, the positional identifier being capable of indicating a relative position of the positional point on the light emitting surface. Since the position determination component determines the position of the to-be-tested point, it is not necessary to visually place the measuring probe over the to-be-tested point, thereby improving the determination accuracy of the to-be-tested point.
