Abstract

A method for measuring a width of a gap of a display module includes the following steps. A sample image of the display module is captured from a viewpoint, the sample image includes a frame region corresponding to a frame part of the display module, an inner region corresponding to a display part of the display module, and a gap region corresponding to the gap between the frame and the display parts. A first line and a second line segments are determined in the sample image, the first line segment is a part of a boundary between the frame and the gap regions, and the second line segment is a part of a boundary between the gap and the inner regions. A distance between the first line and the second line segments is calculated to obtain the width of the gap.

A method for measuring a width of a gap of a display module, comprising steps of:

capturing a sample image of the display module from a viewpoint, the sample image comprising a frame region, an inner region and a gap region, the frame region corresponding to a frame part of the display module, the inner region corresponding to a display part of the display module, and the gap region corresponding to the gap between the frame part and the display part;
determining a first line segment and a second line segment in the sample image, the first line segment being a part of a boundary between the frame region and the gap region, the second line segment being a part of a boundary between the gap region and the inner region;
and
calculating a distance between the first line segment and the second line segment to obtain the width of the gap of the display module.
