Since the projection display plays an increasingly important role in various fields , from manufacturing cost and easy-to-use point of view , the projection display is spread at an alarming rate in people 's lives . With the improved quality of life , people are more and more on the performance requirements of the projector , which also resulted in a the projector performance test links become a particularly important step in the production process of the projector . This thesis is focused on tests and test methods of projection display performance improvements initiated . The main projection display the status quo and development of the industry in the first part of this article . Four projection projector display technologies - LCD , DLP , LCoS and GLV comparison; introduced and explained as well as the performance of the projector , and detailed the projector performance test method , a special presentation specifications of the American National Standard ANSI-1997 test method projection display . Comparison of China, Japan and the United States , the difference in the the projector performance test methods and superiority . The proposed set of projector performance automatic test system for the second part of this article , the system uses color illuminance meter as a detector , detector stepper motor driven scanning probe in the two-dimensional projection plane . The system can scan the projection surface , with a positioning accuracy , high accuracy, high speed , easy operation , etc. . In this paper, the use of automatic test system to test a large number of projectors analysis , there is a certain degree of error found that current testing methods . The spirit of looking for the easy to operate , and the authenticity of the projector closer to the principle of energy , this paper has made ??some improvements on the test methods , major improvement DLP projector flux, contrast , illumination uniformity and chroma uniformity test method , proposed separately luminous flux testing Act 4:00 , 4:00 contrast test , 5:00 ( 0.9 FOV ) Act, illumination uniformity and chroma uniformity test method . Confirmed by a large number of experimental test , performance test the feasibility and reliability of the improved method . Part in the third part. Finally, the research topic , a summary of the work , and pointed out a new direction .
