Embodiment Construction

[0018] like figure 2 , image 3 As shown, the specific steps of the LED splicing display screen construction method based on surface color screening of the present invention are as follows:

[0019] Step 1. Place the display box 1 flat on the fixed bracket 2 in the darkroom;

[0020] Step two, such as image 3 As shown, turn on the LED light source 3, and let the light beam irradiate the upper surface of the display box 1 at an inclination angle a of 45° to 60°. 1, and then name the photo and display box 1 as 1;

[0021] Step 3, repeat steps 1 and 2, place all the display cabinets of the LED splicing display on the bracket 2 in the dark room in turn, take pictures with the camera and name the photos and the corresponding display cabinets as 1, 2, ... (can be consecutive numbers or discontinuous numbers);

[0022] Step 4, such as Figure 4 As shown, according to the principle that the color of the photos does not exceed the recognizable range of the human eye, select a n...

Abstract

The invention relates to a method for building a LED color display screen based on surface color screening. The method is as follows: sequentially place all the display cabinets of the spliced ​​display screen in a fixed area in a dark room and use a camera to take pictures of the center of the display cabinets. , name each photo and the corresponding display box accordingly; select photos with the same number as the number of columns on the display screen and similar colors as any row of the photo array; use the color of the row of photos as a reference Arrange from light to dark from top to bottom to form a photo array with the same number of rows and columns as the cabinet displayed on the display screen, so that the color difference between the two adjacent photos up and down does not exceed the range that can be recognized by human eyes; finally, according to the photos The arrangement order of the photos in the array Use the display box to build the display screen. The present invention effectively solves the problem of color inconsistency on the surface of the display screen, and at the same time shortens the construction time and reduces the production cost.

Description

technical field [0001] The invention belongs to the technical field of large-screen display, and relates to a construction method of an LED splicing display screen based on surface color screening. Background technique [0002] In recent years, with the continuous improvement of people's demand for display equipment and the rapid development of LED full-color display products, the requirements for the overall surface color consistency of display products are getting higher and higher. At present, due to the different background colors of the display units, during the construction process of the cabinet, it is often encountered that the surface color is inconsistent, such as figure 1 As shown, it leads to repeated disassembly and assembly during the construction process, which wastes manpower and increases costs. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a LED splicing display construction method based on s...
