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 by this display screen, 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 stock information.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 the contradiction that machine volume dwindles and needs giant-screen to show.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 light, 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) 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 display screen is reduced;
(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 also than higher, is unfavorable for practical application.
Scheme three,
Shown in Fig. 2 B, at giant-screen application facet prior art such as 01215900.X, adopt Optical Fiber Transmission to amplify device shown, daylight opening adopts light transmitting fiber 3, and the other end stretches into circular-arc light head 2 interior images with each Optical Fiber Transmission and amplifies, and 1 is bracing frame, 4 is the fiber support thing, be unsettled between the optical fiber of center section, some demonstration occasions that this method relatively is fit to image is amplified, volume ratio is bigger.
