Technical Field
The invention relates to the field of spliced display screens, in particular to a method and a device for processing a splicing seam of a spliced display screen.
Background
In recent years, large-size screens are developed rapidly and widely applied to the fields of communication, electric power, military command mechanisms and the like. The large screen is formed by splicing a plurality of display units, and is generally divided into a DLP spliced display screen, an LCD spliced display screen, an OLED spliced display screen and the like.
However, after the display units are spliced with each other, a physical seam with a certain width is left between the adjacent display units, and a large screen inevitably appears at the physical seam when an image is displayed. For example, the DLP tiled display screen is formed by individual DLP display units tiled in a matrix of rows and columns, and an optical display at a physical tiled position between the DLP display units is discontinuous, which causes an optical tiled gap of about 0.5mm, and affects the display effect, as shown in fig. 1. In the LCD splicing display screen and the OLED splicing display screen, because each LCD/OLED display unit has a frame and a physical splicing seam, an optical splicing seam on the display vision exists. Because of the optical discontinuity at the splicing part, the optical splicing seam in the display vision is a black line, which seriously affects the whole effect of large-screen splicing display.
In order to eliminate the prior art as much as possible, there are generally two methods for eliminating the physical splicing seam: the first method is to add an LED dot matrix on the frame of the display unit, and the method has higher cost, is not easy to produce in quantity and has not ideal display effect; the second is to achieve the refraction effect by bending the glass, the method can realize that the visual angle for watching seamless content is smaller, and even when the visual angle is larger, enlarged splicing seams can be watched; such curved glass is susceptible to ambient light, and a viewer may more easily view brighter ambient light through the curved glass portion, thereby affecting the visual effect.

The grid is arranged on the picture to be displayed, the lines of the grid are similar to the splicing seams, and the non-grid line area displays normal image picture content, so that an observer can see the same image as the existing display mode, and the optical splicing seam effect caused by the physical splicing seams can be eliminated visually.
In the above embodiment, all the areas other than the grid lines are added to form a total display area in which normal picture content is displayed so that the viewer sees the entire display content.
As shown in fig. 2, the specific steps of this embodiment include:
s101: obtaining the width D of the horizontal splice jointHAnd the width D of the vertical splicing seamV；
When the steps are realized, the large-screen display screen is formed by splicing a plurality of display units, horizontal splicing seams and vertical splicing seams with certain widths are formed between adjacent display units in the horizontal direction and the vertical direction in the splicing process, and the width of the horizontal splicing seams and the width of the vertical splicing seams are required to be obtained in step S101.
S102: according to the width D of the horizontal splicing seamHAnd the width D of the vertical splice seamVMaking a grid on a picture to be displayed, wherein the grid is displayed as a line of a splicing seam color in an image processing mode, and displaying the content of a normal picture as picture pixel points in a non-grid line region as shown in fig. 3;
s103: synthesizing a picture to be displayed with a grid template to form a picture containing grids;
s104: and outputting and displaying the picture containing the grids.

As an optional implementation manner, step S102 specifically includes:
according to the horizontal splicing seam DHAnd the width D of the vertical splicing seamVAnd respectively setting the line width in the horizontal direction and the line width in the vertical direction of the grid, and manufacturing a grid template.
As another alternative, before or after step S102, the following steps may be further performed: receiving an external image signal, in step S103, before or after the picture to be displayed is synthesized with the grid template, scaling the image signal to obtain the picture to be displayed, that is, before the grid template is synthesized with the picture to be displayed, scaling the picture to be displayed, and then synthesizing the scaled display picture with the grid to form the picture containing the grid, or synthesizing the picture to be displayed with the grid template to obtain the picture containing the grid, and then scaling the pictures therein. This step may scale the input image signal to the desired resolution and then display it in the grid.
As an optional implementation manner, when the grid template is manufactured in step S103, the line area ratio of the whole grid area is dynamically adjustable (e.g., 5-50%), the line area ratio is not too large, otherwise the picture resolution is sacrificed. Further, the distance between the horizontal lines of the adjacent grids can be determined according to the area ratio of the lines.
Furthermore, the distances between the horizontal lines of the grid are the same; and/or the distance between the vertical lines of the grid is the same.

Specifically, for example, the horizontal line width of the grid is the number of unit pixels of the standard line image multiplied by the horizontal scaling, and the vertical line width of the grid is the number of unit pixels of the standard line image multiplied by the vertical scaling. Wherein the scaling ratio is equal to the width of the joint divided by the center distance between adjacent display physical pixels of the display screen, specifically, the horizontal scaling ratio is equal to the physical width D of the horizontal jointHHorizontal direction physical pixel center distance, vertical scaling equal to vertical splice joint physical width DVVertical physical pixel center spacing.
As an optional implementation manner, in order to provide a better visual effect, when the picture is displayed on the tiled display screen in step S104, the horizontal stitching seams and/or the vertical stitching seams on the tiled display screen coincide with a certain line on the grid, that is, all the vertical stitching seams and the horizontal stitching seams on the tiled display screen are covered by the line on the grid;
