Abstract
The present invention relates to a kind of LED colorful display screen building methods based on surface color screening, this method is as follows: successively lying in dark indoor fixed area mosaic display screen with all display cabinets and shows that cabinet center is taken pictures with camera face, is named accordingly each photo and corresponding display cabinet；Pick out that quantity is equal with columns on display screen, any a line of photo as photo array similar in color；Using the row photo color as benchmark by all photos according to the sequence of color from top to bottom from light to dark be arranged in one with cabinet line number and the identical photo array of columns are shown on display screen so that two neighbouring photo color color difference are no more than the identifiable range of human eye；Display screen is finally built with display cabinet according to putting in order for photo in photo array.The present invention shortens while effectively solving display screen surface color problem of inconsistency and builds the time, reduce production cost.
Description
Technical field
The invention belongs to Large Screen Display Technology fields, are related to a kind of LED colorful display screen based on surface color screening
Building method.
Background technique
In recent years, the continuous improvement with people to display device requirement, the rapid development of the full-color display product of LED are right
It is higher and higher to show that the overall surface colour consistency of product requires.At present since display unit background color is different, cabinet is caused to exist
In build process, it is inconsistent to frequently encounter surface color, as shown in Figure 1, leading to the repeated disassembled and assembled in build process, wastes people
Power increases cost.
Summary of the invention
Technical problem to be solved by the invention is to provide one kind can effectively solve the problem that display screen surface color inconsistency
Problem simultaneously reduces the LED colorful display screen building method based on surface color screening for building the time.
In order to solve the above-mentioned technical problem, the LED colorful display screen building method of the invention based on surface color screening
Include the following steps:
Step 1: display cabinet is lain in dark indoor fixed area；
Step 2: opening LED light source, makes light beam with 45 °~60 ° inclination angles irradiation display cabinet upper surface, stablize to illumination
Afterwards, it shows that cabinet center is taken pictures with camera face, the photo of the display cabinet is obtained, then to photo and the display cabinet
It is named accordingly；
Step 3: repeat Step 1: two, successively taken pictures to mosaic display screen with all display cabinets and to photo and
Corresponding display cabinet name；
Step 4: picking out columns in quantity and display screen according to the principle that photo color is no more than human eye recognizable set
Equal photo and any a line as photo array；Then using the row photo color as benchmark by all photos according to face
The sequence of color from top to bottom from light to dark is arranged in a photo array, so that two neighbouring photo color color difference do not surpass
Cross the identifiable range of human eye；The line number and columns of cabinet are shown in the line number and columns of the photo array and display screen to be spliced
It is identical；
Step 5: building display screen according to putting in order for photo in photo array；If ranks difference where any photo
For n, m, then the position of the corresponding display cabinet of the photo on a display screen is that n-th, m is arranged.
The LED light source is 100WLED bulkhead lamp.
The present invention carries out arrangement to corresponding display cabinet according to the sequence of photo color light and shade gradual change and builds display screen,
While effectively solving display screen surface color problem of inconsistency, shortens and build the time, reduce production cost.

Specific embodiment
As shown in Figure 2 and Figure 3, the LED colorful display screen building method specific steps of the invention based on surface color screening
It is as follows:
Step 1: will show that cabinet 1 is lain on the fixed bracket 2 of dark indoor location；
Step 2: as shown in figure 3, opening LED light source 3, makes light beam with table on 45 °~60 ° inclination angle a irradiation display cabinets 1
Face shows that the center of cabinet 1 is taken pictures with 4 face of camera, obtains the photo of the display cabinet 1, then after illumination is stablized
The photo and display cabinet 1 are named as 1；
Step 3: repeating Step 1: two, mosaic display screen is successively lain in into secretly indoor bracket with all display cabinets
It on 2, is taken pictures with camera and photo and corresponding display cabinet is named as 1,2 ... ... and (can be continuous number or not
Continuous number)；
Step 4: as shown in figure 4, picking out quantity according to the principle that photo color is no more than human eye recognizable set and showing
The equal photo of columns and the 6th row as photo array in display screen, then using the row photo color as benchmark by all photographs
Piece is arranged in a photo array according to the sequence of color from top to bottom from light to dark, so that two neighbouring photo colors
Color difference is no more than the identifiable range of human eye；The row of cabinet is shown in the line number and columns of the photo array and display screen to be spliced
Number is identical with columns；
Step 5: building display screen according to putting in order for photo in photo array；If ranks difference where any photo
For n, m, then the position of the corresponding display cabinet of the photo on a display screen is that n-th, m is arranged.It is respectively shown on the display screen built
The name of cabinet is shown in Table 1.
