Problems solved by technology

[0005] 1. Due to the need to classify the LED lamps first, the cost of the product is increased
[0006] 2. Since the LED modules or modules are calibrated one by one, when the time, environment and operation are inconsistent, it is inevitable that some LED modules or modules will have brightness differences or chromatic aberrations that can be observed by the naked eye, so it is necessary to carry out Secondary or tertiary calibration increases work intensity and reduces calibration efficiency
[0007] 3. There is also a certain color error in the camera itself, which affects the color point correction effect of the LED display

Embodiment Construction

[0050] Below, the present invention will be described in detail with reference to the accompanying drawings.

[0051] This embodiment provides a full-screen color correction method for an LED display and its implementation system, such as figure 1 , figure 2 with image 3 shown.

[0052] Among them, the method can be divided into three stages, the first stage is the preparation stage:

[0053] Step 101, determine system parameters. Start the correction software, and determine the parameters of the full screen of the LED display screen 40 by the correction computer 50. offset, etc.;

[0054] Step 102, full screen partition. According to the resolution of the LED display screen, the LED display screen 40 is divided into subregions matching the resolution of the camera 60 by calibrating the computer 50. In this embodiment, four subregions are divided;

[0055] Step 103, pixel positioning of the partition. Choose a partition, operate the correction computer 50 to view and...

Abstract

The invention provides a full-screen color correction method for an LED display and an implementation system thereof, wherein the system comprises a correcting computer, a camera, an optical tester, an integrating sphere, a display control computer, an LED controller and a scanning control panel, wherein the camera and the optical tester respectively carry out parameter sampling on the partitions and full screen of the LED display, and after correction of brightness and chromaticity on the pixel level and the module level of the partitions and the full screen on the correcting computer, the corrected data are transmitted to the scanning control panel of the LED display and stored. The full-screen color correction method and the implementation system thereof of the invention realize full-screen color correction of the LED display, and overcome the defect that after LED modules are corrected one by one by a conventional discrete correction method, when the time, environment and operation are inconsistent, individual LED modules have brightness or chromatic aberration observable by naked eyes, thereby improving the correction quality and correction efficiency.

Description

technical field [0001] The invention relates to the technical field of LED display screens, in particular to a full-screen color correction method for LED display screens and a system for realizing the same. Background technique [0002] Due to the production process, LED tubes have inconsistencies in brightness and wavelength, which leads to the need for color correction for displays using LED tubes. [0003] At present, the color correction method of the LED display screen is: classify the LED lamp tubes of different colors according to the brightness and chromaticity, and use the lamp tubes of the same grade to form the LED display screen. Or use a conventional discrete correction method to take pictures of the red, green, blue, and white colors of dozens or hundreds of modules or module units that make up the LED display, and input the photos into the computer for brightness analysis and analysis. Its homogenization processing, the processed data is input into the LED m...
