Description
Technical field
The invention belongs to the image display technology field, relate in particular to a kind of method and device of eliminating seam between spliced display screens.
Background technology
Current, along with the continuous progress of electronic information technology, increasing computing machine just develops towards the direction of miniaturization, and in miniaturization, the ability of the deal with data of computing machine has also obtained reinforcement, and its treatable data type of institute also more and more widely.People can use small-sized pocket computer to finish large-scale data processing, storage and compile work, thus routine work that is convenient for people to greatly and life.For example, can adopt notebook computer that stock information, map datum and view data are handled, and on display screen, show corresponding contents according to result.Yet because the miniaturization of computing machine must cause its display screen significantly to dwindle thereupon, this display screen that dwindles can bring the difficulty of watching to the user.Especially for the above data that display quality is had relatively high expectations, this display screen that dwindles can't satisfy the requirement of display quality, thereby makes the user at large to obtain corresponding information by portable computer, thereby makes troubles to the user.For instance, when the user downloads map datum by notebook computer, because display screen is less, therefore, the user can't clearly obtain its needed map that has bulk information by this display screen, such as being the partial, detailed view of determining the big figure of approximate location and showing route, and for example, if the user handles stock certificate data by notebook computer, because this display screen is less, then the user can't clearly obtain corresponding a large amount of stock information, such as deep bid general trend and personal share details.In addition, because computing machine is more and more stronger for the processing power of the multi-medium data of for example video etc., therefore, the user for example also can utilize, and the such portable equipment of notebook computer carries out video playback, although these portable equipments possess enough video data processing poweies, because the size restrictions of its display screen, make that can't give the beholder can't obtain the visual enjoyment that giant-screen can provide, and has reduced the video data display capabilities of portable equipment thus.In addition, carry out also needing display screen to have large-size, to make things convenient for user's actual use in the process of engineering drawing and multiwindow operation using a computer.
This shows, in the process of current computer miniaturization, exist machine volume and dwindle and need giant-screen to show such contradiction.Current, adopt the display screen splicing to solve this contradiction usually, increase screen size by a plurality of display screens being spliced, reaching under the prerequisite that does not increase equipment size.In addition, in actual applications, also exist the occasion that many needs carry out large-scale demonstration, for example airport, railway station, sports tournament and large-scale exhibition.In these occasions, need utilize the very big display screen of size to provide corresponding information for the far people of distance, and because in manufacture process, the manufacturing cost of kinescope and production difficulty can significantly rise along with the increase of required size, therefore, for the occasion of the large-scale demonstration of needs, need the display screen splicing equally.
In the prior art, the display screen splicing that adopts usually comprises: the splicing of CRT kinescope, LCD splicing and projector's splicing.Because projector is comparatively harsh to the requirement of ambient light, in the stronger place of ambient light, can't see image clearly, therefore, only be suitable for indoor use, its range of application is narrower, and for splicing of CRT kinescope and LCD splicing, its subject matter is, no matter how close the display screen that will splice, in splicing, always between display screen, there is piece, is specially:
CRT gets on the video screen of inside surface of kinescope by electronics to show, its kinescope is made by certain thickness glass shell, the centre is evacuated, in order to guarantee certain intensity, glass shell need have certain thickness, thereby the edge of CRT kinescope can not dwindle, its minimum widith is the thickness of glass shell, and this minimum widith is generally 5 millimeters;
The technology of LCD is that the liquid crystal that can become color and gray scale under the voltage effect is filled in the little space, display is formed in a plurality of so little spaces, constitute a complete display screen, to prevent liquid crystal leakage, the width at this edge usually can not be less than 5 millimeters with the lapping protection at the edge of LCD;
Therefore, because the border width that CRT and LCD are had separately makes to occur piece inevitably in the display screen splicing.In order to address this problem, the following technological means of available technology adopting is eliminated piece:

(1) this scheme can only reduce the piece width, can not eliminate piece fully; After adopting this scheme, the edge of display screen still can be seen, its formed piece thickness is approximately 1 millimeter, this also accepts reluctantly for large screen display, but occasion for those portable set the small screen splicings, then beyond affordability, show: because the small screen splicing occasion generally all is that portable equipment splices, and user's eyes are closer usually from the display screen of portable set, therefore, present fairly obviously even there is a slit all can see, thereby picture quality is damaged, and then cause user's strong dissatisfaction;
(2) adopt this scheme, the thickness of the optical glass mirror of being placed on the display screen is bigger, thereby can increase the volume and the quality of display screen, thereby reduces its portability; For example, two LCD merge, and its piece width is 10 millimeters, and then Shang Mian optical glass thickness is 25 millimeters, and the optical glass of this thickness can obviously increase the volume and the quality of display screen, makes it be unfavorable for carrying;
(3) because this scheme need be compressed and processing and amplifying the image border, therefore, can cause damage to image itself;
In addition, need compress and the area of the edge image of processing and amplifying because this scheme need accurately calculate, therefore, it is complicated to make that this scheme realizes, is unfavorable for practical application;
Scheme two:
Adopt Fresnel magnifier (FRENSNAL LENS) to realize eliminating piece: in this scheme, the Fresnel magnifier all amplifies the image of each display screen according to certain multiplying power, to mask the middle piece of two displays, referring to Fig. 2,20 is two display screens that independently are stitched together among the figure, 11 is the Fresnel magnifier, and 12 are the pressure-sensitive plate, and 13 is flexible film; Though this method can be eliminated piece, this method has following shortcoming:
(1) in order to obtain suitable enlargement factor, the Fresnel magnifier must leave display 20 1 segment distances, otherwise image can't amplify, and can cause display thicker like this, thereby increase the volume of display screen, and the portability of equipment that this method is constituted reduces;
(2) the Fresnel magnifier produces the diffraction phenomenon in order to make the bending of light of passing this magnifier, thereby form the effect of magnifier, must be covered with tiny serrate concentric circles striped on its surface, this striped can cause certain infringement to image, thereby reduces picture quality;
In addition, the processing cost of Fresnel magnifier is also than higher, and costing an arm and a leg influences practical application.
