Display brightness uniformity detection fixture

Abstract

This utility model relates to the field of auxiliary positioning technology for display energy efficiency testing, and provides a display brightness uniformity testing fixture, including a movable plate, a fixed column on the movable plate, and multiple movable columns that can move left and right on both sides of the movable column. The fixed column and the movable columns are respectively provided with a first sliding sleeve and a second sliding sleeve that can move up and down. Each first sliding sleeve and second sliding sleeve is equipped with a brightness sensor. This display brightness uniformity testing fixture, by setting a fixed column and the movable columns on both sides, and setting multiple sliding sleeves on the fixed column and the movable columns, and installing brightness sensors on the surface of the sliding sleeves, forms an adjustable-size grid in the same plane to adapt to different screen sizes, and performs detection at multiple points on its surface. This saves the time spent finding measurement points when measuring screen brightness uniformity and improves the accuracy of the measurement.
