Method and device for eliminating seam between spliced display screens

Abstract

The method includes steps: based on principle of total reflection, optical element shifts segmented original sub images to position of edge joint between display screens; and re-merges shifted each segmented image to restore the original image. The invention also provides device for eliminating edge joint between scabbed display screens. The device includes image segmentation module, image shift module, and image restoring module. The segmentation module is in use for segmenting original image, and transmitting each part of segmented original sub images to the image shift module. The image shift module is in use for shifting segmented all or parts of original image toward to position of edge joint between scabbed display screens in order to cover the edge joint. The image-restoring module merges and restores the shifted images to the original images.

Description

technical field [0001] The invention belongs to the technical field of image display, and in particular relates to a method and a device for eliminating seams between spliced ​​display screens. Background technique [0002] At present, with the continuous advancement of electronic information technology, more and more computers are developing in the direction of miniaturization. At the same time of miniaturization, the computer's ability to process data has also been strengthened. The types of data it can process is also becoming more widespread. People can use small portable computers to complete large-scale data processing, storage, and collection work, which greatly facilitates people's daily work and life. For example, a notebook computer may be used to process stock information, map data, and image data, and display corresponding content on a display screen according to the processing results. However, due to the miniaturization of the computer, its display screen wil...

Problems solved by technology

[0011] (1) This solution can only reduce the width of the patchwork, but cannot completely eliminate the patchwork; after adopting this solution, the edge of the display screen can still be seen, and the thickness of the formed patchwork is about 1 mm, which is suitable for large screens. The display is barely acceptable, but it is difficult to accept the splicing of small screens of portable devices. The performance is as follows: because small screen splicing is generally done by portable devices, and the user's eyes are usually closer to the display screen of the portable device , therefore, even if there is a little gap, it will be very obvious, which will damage the image quality and cause strong dissatisfaction among users;

[0012] (2) With this solution, the thickness of the optical glass mirror placed on the display screen is relatively large, which will increase the volume and quality of the display screen, thereby reducing its portability; for example, if two LCDs are combined, the seam width is 10 mm, the thickness of the optical glass above is 25 mm, and the optical glass of this thickness will significantly increase the volume and quality of the display screen, making it unfavorable to carry;

[0013] (3) Since the solution needs to compress and enlarge the edge of the image, it will cause damage to the image itself;

[0017] (1) In order to obtain a proper magnification, the Fresnel magnifying glass must be separated from the display 20 for a certain distance, otherwise the image cannot be enlarged, which will cause the display to be relatively thick, thereby increasing the volume of the display and reducing the portability of the display;

[0018] (2) In order for the Fresnel magnifying glass to bend the light passing through the magnifying glass and produce diffraction phenomenon, thereby forming the effect of the magnifying glass, the surface must be covered with small saw-dot-shaped concentric circle stripes, which will cause certain damage to the image. damage, thereby reducing image quality;

[0019] In addition, the processing cost of the Fresnel magnifying glass is relatively high, and the high price affects the practical application
