The method includes: in a dark room environment, collecting a projection light point on a projection screen projected by a projection system, to obtain a projection image; adjusting the test pattern, so that a first projection light point corresponding to the white point of a first coordinate on the test pattern after being projected by a first color light source is located in a center of the projection image; obtaining a second and/or a third projection light points corresponding to the white point of the first coordinate after being projected by a second and/or a third color light sources from the projection image; and adjusting an assembly parameter of the projection system according to a position of the second and/or the third projection light points and a position of the first projection light point."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for correcting color convergence error","description":"Provided are a method and an apparatus for correcting a color convergence error.
