Micro LED screen specification adaptive multi-point chromaticity measurement device

Abstract

A disclosed Micro LED screen specification adaptive multi-point chromaticity measuring device comprises an outer frame and a limiting strip, a protection pad is fixedly connected to the inner side of the outer frame, a detection opening is formed in the inner side of the protection pad, sliding grooves are formed in the upper side and the lower side of the front end of the outer frame, the sliding grooves are formed in the outer side of the detection opening, sliding blocks are fixedly connected to the upper side and the lower side of the rear end of the limiting strip, the sliding blocks are movably connected to the inner sides of the sliding grooves, the inner end of the limiting strip is fixedly connected with expansion pull pieces, and the expansion pull pieces are movably connected to the left side and the right side of the inner end of the detection opening. According to the Micro LED screen specification adaptive multi-point chromaticity measuring device, a first driving motor drives a detection probe to horizontally move along a transverse sliding rail, the surface of an LED screen is horizontally and sequentially detected, detection dead angles are avoided, the detection accuracy is improved, non-detection parts in the periphery of the LED screen can be protected through deformable structures of a protection pad and a detection opening, the detection accuracy is improved, and meanwhile, the size of the detection opening can be adjusted to change the detection range of the LED screen.

Description

technical field [0001] The invention relates to the technical field of electronic testing equipment, in particular to a Micro LED screen specification self-adaptive multi-point chromaticity measurement device. Background technique [0002] Micro LED screens refer to the use of organic materials in the stacks of pixels that produce light. The display technology has the characteristic of self-illumination. When a current passes through, the organic materials that make up each pixel will emit light to display images. Pixels that do not need to display images do not need current to pass through, thereby achieving true black and power-saving characteristics. , In addition, OLED screen technology also has the characteristics of thin, light, bendable and broad application prospects. [0003] The display chromaticity measurement is an inspection procedure that the display must go through when it is produced and leaves the factory. If the chromaticity of the LED display is uneven, i...
