The device of the present invention can ensure the precision of the test and the stability of test results.

Description

technical field [0001] The invention relates to the production field of liquid crystal display screens, in particular to a test fixture used for light testing of liquid crystal screens. Background technique [0002] Existing screen light test instruments are sensitive to light, and the test equipment usually does not have relevant supporting tooling. There are the following problems: the test position is manually positioned during the test process, which affects the consistency of the test results. In addition, the test results are also easily affected by external light. , causing deviations in test results. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects of the existing optical testing instruments that affect the testing accuracy due to manual positioning, and provide a test fixture that can ensure the accuracy of the test and the stability of the test results. [0004] The present invention solves...
