Problems solved by technology

[0006] It can be seen from the above that for the existing calibration method of the LED cabinet in the factory, the LED cabinet needs to be manually placed in the preset position. If there is a deviation between the placement position and the set position, it will affect the data collection of the LED cabinet ;In addition, images of multiple cabinets cannot be collected at the same time; in addition, two calibration personnel are required to move the cabinets and one calibration personnel is required. The cooperation between the three people leads to longer time-consuming manual calibration

Abstract

The invention relates to an LED display module brightness and chromaticity correction production line, which includes: a track; a plurality of workstations arranged on the track and including a plurality of first darkroom stations; a plurality of image acquisition equipment, respectively arranged on the plurality of first darkroom stations; A darkroom station is used to capture images of different colors displayed sequentially by LED display modules to be corrected mounted on the track to obtain color image data; and a track computer system is used to control the movement of the track and control all The LED display module to be corrected displays the different color images and connects signals to the multiple image acquisition devices to obtain the color image data. The present invention collects various color image information of LED display modules in a pipeline manner through multiple image acquisition devices, improves correction efficiency and makes data collection more accurate, avoids data collection errors caused by different image acquisition devices correcting different LED display modules, and Reduces correction manpower.

Description

technical field [0001] The invention relates to the technical field of display correction, in particular to a production line for brightness and chromaticity correction of LED display modules. Background technique [0002] With the development of the LED display industry, the application fields of LED display are becoming more and more extensive. Advertising media, road traffic information display, dispatching command center information display, performances and gatherings are widely used in LED display. However, these displays will more or less have uneven phenomena such as mosaics caused by brightness and chromaticity deviations. It is necessary to use image acquisition equipment to correct each LED light to make the LED display screen smooth as a mirror. [0003] The calibration of the LED cabinet only needs to be carried out in the factory building, which consumes relatively little manpower and material resources. At present, display manufacturers tend to choose the box...
