Optical apparatus for splicing wall display equipment

Abstract

The invention provides an optical device which is used for assembly wall display equipment, comprising a microlens array and an image receiving layer which are sequentially arranged at the front of the display equipment according to the sequence from front to rear; the microlens array and the image receiving layer are fixedly connected with each other. The optical device of the invention solves the seam assembly problem between each assembly display unit of the assembly wall, better ensures the continuity and integration of the display image, has the advantages of simple structure and convenient installation, and is applicable to various assembly wall display equipments.

Description

technical field [0001] The present invention relates to a display device, in particular to an optical device for a video wall display device. Background technique [0002] In recent years, with the rapid development of flat-panel display technology represented by PDP, LCD, etc., flat-panel display equipment has gradually become the mainstream of display technology due to its advantages of high brightness, small size, and light weight, and has greatly replaced CRT and rear projection. device trends. Although a single flat-panel display device can meet the display requirements of general occasions, it cannot meet the requirements for occasions that require large-screen display (such as a control room). Therefore, splicing flat-panel display devices to achieve large-screen display becomes a natural choice. [0003] Although the current flat-panel display devices have many advantages, their use in splicing is limited to a certain extent. The reason is that the flat-panel displa...

Problems solved by technology

The Chinese invention patent with the application number 200410091098.2 "A method and device for eliminating seams between spliced ​​display screens" proposes a method of solving splicing gaps with image translation, but this method is suitable for splicing in the form of front projection and cannot be used for rear projection or flat panel display device

The Chinese utility model patent "optical fiber magnified display" with application number 00225268.6 proposes the concept of optical fiber magnified display, which uses optical fibers with different thickness at both ends to amplify the image geometrically. Deteriorating the display screen image quality

The Chinese invention patent "Assembled Plasma Display Device" with the application number of 200310106028.5 proposes to use the magnification of the lens to enlarge the image projected on the screen, so as to make up for the combination of display images due to the use of small plasma display units. However, in this scheme, one plasma display unit should correspond to more than one lens, and the spacing between adjacent plasma display unit bodies must be precisely adjusted, and the distance between adjacent plasma display units must be adjusted. Only when the edge light is projected onto the screen by the lens and the light spot is compatible with the resolution can the goal of seam elimination be achieved. This requires too high precision for the arrangement of the plasma display unit and the lens, which is difficult to achieve in practical applications.
