Substrate detection apparatus and protrusion height detection method
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.
