Luminance and chrominance correction production line for LED (light-emitting diode) display modules

Abstract

The invention relates to a luminance and chrominance correction production line for LED (light-emitting diode) display modules. The production line comprises a track, a plurality of stations, a plurality of image acquisition devices and a track computer system, wherein the stations are arranged on the track and include a plurality of first darkroom stations; the image acquisition devices are arranged in the first darkroom stations respectively, and used for performing image shooting on pictures different in color and sequentially displayed by the to-be-corrected LED display modules loaded on the track respectively to obtain color image data; the track computer system is used for controlling the motion of the track and controlling the to-be-corrected LED display modules to display the pictures different in color, and is in signal connection with the image acquisition devices to obtain the color image data. According to the production line, various color image information of the LED display modules is acquired in an assembly-line manner through the image acquisition equipment, so that the correction efficiency is improved, the data acquisition is relatively accurate, the data acquisition errors caused by correction of different LED display modules by different image acquisition devices are avoided, and the correction manpower is reduced.

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...

AI Technical Summary

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
