The present invention relates to a method and a device for determining regions to be detected on a display motherboard. The method comprises acquiring a first image, acquiring detection parameters of the regions to be detected, acquiring second images which have a resolution higher than that of the first image, and correcting obtained detection parameters based on the second images. Compared with the prior art, the present invention can improve accuracy and efficiency of detection of a display motherboard.

Method and device for detecting boundary of region on display motherboard

The present invention relates to the technical field for detecting a display substrate, and discloses a substrate detection apparatus and a protrusion height detection method. The substrate detection apparatus comprises a carrier configured to carry a substrate to be detected as well as a sensor bracket, a height measuring sensor is disposed at one end of the sensor bracket, the height measuring sensor is of a cone structure, and a diameter of an end face, which is configured to detect the substrate to be detected, of the height measuring sensor is smaller than that of the other end face. The substrate detection apparatus and the protrusion height detection method can solve problems such as inaccurate measurement and inaccurate calculation for a height of a protrusion defect on a color filter substrate.
