LED display module detection and calibration equipment

Abstract

The invention relates to LED display module detection and correction equipment. The equipment comprises an equipment running machine platform, an image acquisition device and an optical cavity. The equipment running machine platform comprises a transfer track, a sliding seat and a fixture platform; the transfer track is provided with a detection position; the sliding seat is slidably mounted on the transfer track; the fixture platform is used to carry an LED display module and is fixedly mounted on the sliding seat. The optical cavity is provided with a light entrance part, a reflection mirror group and a light exit part; the light entrance part is located at the bottom of the optical cavity and right above the detection position. The reflection mirror group is arranged in the optical cavity and is used for reflecting image lights entering from the light entrance part into the optical cavity to form outgoing image lights transmitted to the light exit part, wherein the image lights reach the detection position and are emitted by the LED display module carried by the fixture platform. The image acquisition device is arranged adjacent to the light exit part, and is used for collecting the outgoing image lights for the detection and calibration of the LED display module. Therefore, the equipment can realize the automatic detection and calibration of the LED display module, and greatly improves the production efficiency.

Description

technical field [0001] The invention relates to the technical field of LED detection and correction, in particular to the detection and correction of LED display modules. Background technique [0002] The point-by-point brightness and chromaticity correction system collects the brightness and chromaticity of each LED light point on the LED display or LED display module such as an LED cabinet or LED light board through the camera, and obtains the LED display or LED display module through calibration software analysis. The correction coefficients of each LED light point on the screen, and then apply the correction coefficient to the LED display screen or LED display module through the control system, so as to realize the coefficient adjustment of each LED light point, and then realize the brightness and chromaticity of the LED light points are highly consistent sex. [0003] The detection process of the brightness and chromaticity difference of the LED display module is as fo...

Problems solved by technology

[0005] However, in the prior art, LED display module detection and point-by-point brightness and chromaticity correction cannot realize synchronous and automatic operation, and there is a handling process between the two processes, which is not efficient enough; moreover, it is difficult to detect non-compliant brightness and chromaticity errors in the assembly line by naked eyes Range of LED Display Modules
