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 millimeter;
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:

Wherein, 140 is optical lens among the figure, and Fig. 1 a, Fig. 1 b and Fig. 1 c have adopted the optical glass of difformity and structure respectively, and these optical glass can both reach the purpose of enlarged image by its marginal portion to interception of rays; 30 is display screen, and the dark part in the middle of two display screens 30 be the piece between display screen, shown in Fig. 1 a～1c, through the light of optical lens the image of refraction with the amplification marginal portion takes place, thereby makes visible piece width significantly reduce.Though this method can reduce the piece width,, this method has following shortcoming:
(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, makes the portable reduction of display screen;
(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 saw point shape 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.

With the notebook display screen is that LCD is an example, a very thin glass is arranged on the surface of LCD, the glass below is a liquid crystal material, above glass, cover the glassy layer that one deck is combined into by the translation glass unit again, the selection of thickness of glass is decided according to the width of the piece of LCD screen, if self border width of LCD screen is 5 millimeters, then the piece width is 10 millimeters, the distance of the mobile image of translation glassy layer needs is exactly 5 millimeters so, therefore the thickness that can determine glassy layer is generally and is approximately 5 millimeter, this is because minimum at present LCD border width is 5 millimeter, the shape of translation glassy layer such as Fig. 7 or shown in Figure 12, and, glass symmetry on two LCD is placed, toward each other, thereby make the image on two display screens move 5 millimeter to middle piece position respectively, so just piece is narrowed down to minimum degree; In order to reduce the influence of piece, can also above the translation glassy layer, place one deck light transmission film again to image;
Can see, Figure 14 C is the situation that two screens of notebook fold, volume ratio is less, 14D is an opening procedure, 14A is the situation after two screens are opened, there is a splicing seams clearly the centre, 14B be add the translation glassy layer latter two display image all to middle translation the effect behind one segment distance.
2, the mobile phone of band PDA function:
At present along with the development and the swift and violent of digital mobile phone of mobile communication are popularized, the computing power of mobile device improves constantly, on mobile phone, also comprised the PDA function, but, because the display screen of mobile telephone of band PDA function is undersized, therefore can cause input inconvenient, so also can't substitute such as the such mobile office equipment of laptop at present, its main contradiction is exactly the conflict of portable and comfort, if on the mobile phone of band PDA function, contain two display screens that size is the same, when using as mobile phone, as shown in figure 15, make this mobile phone be in folded state, only use one of them display screen, and when carrying out PDA or literal input operation, when perhaps watching character image, shown in Figure 16 A, two display screens are stitched together, then can form a bigger display screen; Because the computing power of embedded mobile processor is become stronger day by day, miniature memory span is also huge to be increased, and therefore, can utilize the mobile phone of this band PDA function to realize the work of similar present notebook fully; Equally, shown in Figure 16 A, in the process that present embodiment splices display screen, also there is piece between the display screen, in this embodiment, adopts embodiment two realization image translations as mentioned above, thereby eliminate piece, thereby obtain the effect shown in Figure 16 B.
In order to reach above effect, need all do dividing processing to the image of two displays, as shown in figure 17, wherein the border width of display screen is 5 millimeters, translation glass needs parallel mobile distance also to be 5 millimeters, the image of left side 5 mm wides of the display screen on the left side will be by a display screen length-5 of translation mm distance, therefore in pretreated process, should move on to the left side to the image of display screen right side 5 mm wides earlier, and then carry out translation by translation glass, and the way and the left side of right side display screen are similar, and only direction is opposite, above this translation glass, cover thin film again, be used to go back original image;
In Figure 17, LCD display and translation glass separate, pass in the translation glass process lossy at the LCD screen image, therefore can be the consideration of putting together of LCD liquid crystal display and translation glass, directly the glass shape on LCD liquid crystal display surface is made the shape of translation glass, so also reduced mounting hardness, as shown in figure 18.
The above only is preferred embodiment of the present invention, and is in order to restriction the present invention, within the spirit and principles in the present invention not all, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
