Method and device for eliminating seam between spliced display screens

Abstract

The method includes steps: (1) collecting original images, which are suitable for image shift in subsequent step (2); (2) shifting the collected images to position of edge joint; (3) restoring the shifted images to original images. The invention also provides device for eliminating edge joint between scabbed display screens. The device includes image collection module, module for shifting original image, and image restoring module. The image collection module is in use for collecting original images, and sends the collected images to the module for shifting original image. The module for shifting original image is in use for shifting the received image to position of edge joint so that the shifted images can cover the edge joint. Receiving the shifted images from the module for shifting original image, the image restoring module 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 proper magnification, the Fresnel magnifier must leave a certain distance from the display 20, otherwise the image cannot be enlarged, which will cause the display to be relatively thick, thereby increasing the volume of the display screen, making the portability of the equipment formed by this method reduce;

[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 zigzag concentric circle stripes, which will cause certain damage to the image , thereby reducing the image quality;

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