Embodiment Construction
[0014] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.
[0015] Example.
[0016] A light source adjustment method for defect detection of liquid crystal screen glass substrate, the design process is as follows:
[0017] (1) Light source model of LCD glass substrate defect detection system
[0018] The light source model for TFT-LCD glass substrate defect detection is shown in the figure.
[0019] in the attached figure 1 , 2 Shown in is the light source illumination model of traditional liquid crystal screen glass substrate defect detection. When installing a light source in an imaging system, we can only estimate the approximate position of the light source during routine operation, but cannot accurately calibrate it...
