Abstract

The invention provides a device for detecting the brightness of a liquid crystal display by using a light reflection method. A supporting rod is slidably mounted in a rotating plate, a movable plate is fixedly mounted at the bottom end of the supporting rod, the movable plate is movably mounted on the rear surface of a push seat, the push seat is connected to the outer surface of a supporting column in a sleeving manner, the supporting column is slidably mounted on the outer surface of a sliding rod, and an ejector rod is fixedly mounted on the inner end surface of the supporting column. When the rotating plate rotates, the movable plate at the top end of the supporting rod is driven to rotate, the movable plate drives the push seat to slide in the supporting column, and meanwhile, the supporting column slides in the sliding rod, so that the supporting column is driven to move up and down on the surface of the sliding rod, after the supporting column moves upwards, an inserting rod at the bottom is separated from a reset rod, and the reset rod pulls a clamping table to move, so that the reflection angle between the liquid crystal display and a reflection lens and the reflection angle between the liquid crystal display and a condensation cover are kept perpendicular all the time, brightness detection between different distances of the liquid crystal display is completed through a light reflection method, and detection is more accurate.

Description

technical field

[0001] The invention belongs to the technical field of liquid crystal display detection, and in particular relates to a detection device for liquid crystal display brightness by using a light reflection method. Background technique

[0002] Liquid crystal display is a flat and ultra-thin display device. It is composed of a certain number of color or black and white pixels. After the display is produced, the generated brightness parameters are particularly important, so it is very necessary to detect the brightness of the display.

[0003] In the traditional brightness detection, it is impossible to detect different distances, the detection is not comprehensive enough, the detection data is not accurate and true, and at the same time, it is impossible to intuitively judge the brightness change of the display device at different distances, and the detection range is limited. Therefore, in view of this, the existing structure and defects are studied and improve...
