Method for removing visual gaps among modules after display screen is spliced and display method

Abstract

The invention discloses a method for removing visual gaps among modules after a display screen is spliced and a display method, and belongs to the field of display screens. The method comprises the steps of S1, obtaining a brightness distribution picture when the display screen is lightened; S2, determining the positions and gap positions of all light points on the brightness distribution picture;S3, calculating to obtain brightness compensation coefficients of the light points at the two sides of each gap and inside each module or all the light points according to the local average brightness difference of the gaps or the non-gaps, or according to the distance of adjacent light points at the two sides of each gap and the distance difference of adjacent light points inside each module; S4, using the brightness compensation coefficients to adjust the brightness of the light points at the two sides of each gap and inside each module or all the light points to visually remove the visualgaps among the modules after the display screen is spliced. Bright and dark lines in gaps among display units of the spliced display screen are visually removed, the visual effect is obviously improved, the achievement steps are simple, and the splicing and installation difficulty and installation cost are lowered.

Description

technical field [0001] The invention relates to the field of display screens, in particular to a method for eliminating visual gaps between modules after display screen splicing and a display method. Background technique [0002] The splicing display screen is a large-scale display device composed of thousands of light point arrays. Due to its large size, in order to facilitate assembly, a modular structure is generally used, and the prefabricated modules are spliced ​​together with appropriate gaps in the middle. [0003] In the process of splicing modules, due to limitations of machining accuracy, assembly process and other reasons, the gap between adjacent modules may be too wide or too narrow, resulting in the distance between the light points on both sides of the gap may be larger or smaller than the lights inside the module The spacing between the points, so that the density of light points at the gap changes. When the distance between the light points on both sides o...

Problems solved by technology

However, this method is time-consuming and labor-intensive. It needs to start from a certain place on the display screen and gradually adjust to the edge in turn. The adjustment of a certain place may cause changes in all gaps; and, limited by the splicing mechanism, the range and accuracy of manual adjustment are also limited. Restrictions; further, the fine-pitch display is easy to knock off the luminous point of the display during the adjustment process; finally, the effect of manual adjustment is judged by the human eye, and the improvement effect and evaluation standards vary from person to person
