Description
Technical field
The utility model relates to the device that LCDs splicing frame is eliminated in the display of a kind of edge, make integrated after liquid crystal display become " seamless " display system of " gross area " " with great visual angle ", and the effect making spliced liquid crystal display reach " seamless " to show.
Background technology
Digital high-definition (2K), the large screen display of ultra high-definition (4K) has play more and more important role.But display screen is all with the black square frame without video after being spliced into giant-screen, and Fig. 1 is 2 (OK) x 2 (row) 4 spliced situations of liquid crystal display (after splicing, diagonal line is 120 English inch).If input a circle with 4 breach and cruciform (equally wide with black square width of frame) to the center (see Fig. 2) of 2x2 mosaic screen, result is 4 breach, cruciform and wide video image does not show with black square frame, (see Fig. 3).If all shown by input signal, result is unacceptable, because inputted video image " division ", the width of black square frame has become a part (see Fig. 4) for video image.Therefore, " to substitute " with the width of display screen black square frame after splicing of the black surround frame without video or some image of " occupying " input video.This for display data, curve, track, on map certain a bit (global location) etc. be all fatal defect.
And the entire display screen that will manufacture more than more than 120 English inch all exists a lot of obstacle in scale of investment, manufacture-e-quipments and materials intensity, yield rate, transport installation etc., also very uneconomical.Manufacture " the unit area cost " of the monoblock display screen of 80 ~ 120 English inch along with screen body size is with exponential form rising, and adopt mosaic screen, cost increases with splicing dimension linearity, and namely its " unit area cost " is substantially constant.
Be used for splicing for dissimilar display screen, the concrete manifestation without the black square frame of video is as follows:
1.0.0 liquid crystal (LCD) display screen:
Liquid crystal uses the most at present, reached the display screen of digital ultra high-definition (4K).But liquid crystal display can have the embedding edge printing signal line by viewing area periphery, and this edge " without video " display (monolateral 2 ~ 4 mm, bilateral 4 ~ 8 mm after splicing).No matter how narrow this edge is, still cannot avoid black square frame, (see Fig. 5) after liquid crystal display is spliced into giant-screen.In order to avoid these black square frames, have " passive " and " initiatively " two class mode process:
1.1.0 passive type
Passive type mainly utilizes the optical principle of reflection or refraction visually to carry out " covering " black square frame, and it can not " recover to show " original input video on width shared by black square frame.Generally there is following several form:
1.1.1 reflective
Cover on the original black surround frame of liquid crystal display with surrounding and liquid crystal display reflective mirror at 45 °, make liquid crystal display in 45 ° of reflective mirrors, " display can be repeated " near the video of black frame edge in viewing area, cause a kind of visual effect (see Fig. 6) not having black square frame.But it still cannot show 4 breach and the cruciform of former input video, (see Fig. 7).
1.1.2 amplify
A) with transparent material make one piece the same with liquid crystal display size, certain thickness material is had to cover on original liquid crystal display, and make " circular arc " at the edge through-thickness of this block transparent material, and this " circular arc " have amplify liquid crystal display can the effect (see Fig. 8) of viewing area periphery video
B) directly make one transparent " circular arc " and bend post, " circular arc " post should be bent be fitted in liquid crystal display and splice on black surround frame (see Fig. 9) after liquid crystal display splicing.
Above-mentioned no matter which kind of mode, when vertical " circular arc " base viewing, " circular arc " amplification of viewing area periphery video can serve the effect (see Figure 10) of part overlaid black square frame to liquid crystal.
But contrary, when watch on out of plumb " circular arc " base, " circular arc " but " amplifies the black square frame of liquid crystal display " must be wider, and along with the increase of this angle, the width of black square frame is wider, and visual angle is 30o, (see Figure 11); Be 45 o, (see Figure 12); Be 60 o, (see Figure 13).
And for several meters, tens meters of even larger sized liquid crystal-spliced giant-screens, each viewing area must " vertically " viewing be unpractical.Therefore, watching the liquid crystal giant-screen that is spliced into by " reflective " form, with " circular arc " base vertical beyond viewing area there will be black square frame than original liquid crystal display " wider ", obviously:
A) splicing quantity and the size of LCDs is limited;
B) can not " recover show " " be substituted " by black surround frame or the original video image of " occupying ";
C) mode of viewing is limited.
1.1.3 optical amplifier is dull and stereotyped
Optical amplifier flat board is based on fiber optic conduction principle, the pel spacing of light input layer (bottom) is equidistantly diffused to light output layer (top layer), make bottom and liquid crystal display pixel one_to_one corresponding, top layer diffuses to the outside dimension (see Figure 14) comprising liquid crystal black surround frame.
1.1.4 white
In order to avoid " impact " of black to vision and the contrast of viewing area and black of black surround frame, the black of black surround frame is changed into " white " or " silver gray ", with gentle this " impact ", but when former input video expresses black elements, " white " frame still produces vision " impact ".
1.2.0 active
Active is " to be substituted " by black square frame without " recover display " on the black surround width of frame face of video or the video image of " occupying ", and the video image that video image that the width face of liquid crystal display black surround frame " recovers to show " and liquid crystal display can viewing area be shown is fused into the width video image the same with former input.This is the display of a kind of edge, and in the display of this edge, need the pixel of " recovering display " that LED or OLED can be passed through, and corresponding circuit realizes, it and the most essential not being both of other forms " covering " black square frame: " recovering to show " " is substituted " by black square frame or the video image of " occupying ", (see Figure 15).
Except above-mentioned liquid crystal display, after the splicing of other display screens, the situation of black square frame is as follows:
2.0.0 rear-projection (DLP) display screen
Rear-projection adopts the mode of back-projection to make display screen.Because projection screen is fixed on very thin framework end face, make rear-projection without the black surround frame of video narrower (monolateral 1.5 mm, bilateral 3 mm after splicing), (see Figure 16).
But no matter how narrow these black surround frames are, and rear-projection still has black square frame after splicing.Simultaneously compared with liquid crystal display, rear-projection is the display technique belonging to older generation, self there are a lot of restriction and defect, as low in brightness, resolution is low (cannot accomplish high definition, ultra high-definition), the life-span is short, maintenance cost is high, thickness is large, need safeguard space etc. behind.
3.0.0 plasma (PDP) display screen
Plasma is a kind of " autoluminescence " pixel display technique, therefore the pixel of these " autoluminescences " can be produced on " " edge of display screen.But these " autoluminescence " pixels still need to obtain and support, the structural thickness therefore supporting these " autoluminescence " pixels is exactly the black surround frame (monolateral 1.5 mm, splicing is bilateral 3 mm afterwards) without video.
Meanwhile, the restriction of plasma display technology self and defect, like biscuiting is burnt, resolution low (cannot accomplish high definition, ultra high-definition), brightness is low, the life-span is short, price is high, power consumption is large etc. (see Figure 17).
4.0.0 LED display screen
LED display is very general.But LED display screen does not generally accomplish that high definition (2K) shows, and it is more difficult to show ultra high-definition (4K).At present, the pixel of LED display screen can accomplish 1.9 mm apart from (Pitch), for digital high-definition standard 1920 x 1080, the size when LED display screen is only had to reach 2052 x 3648 mm, namely when (1.9 x 1920) x (1.9 x 1080), can show high definition (2K) video image completely, but problem is:
A) HD video shows on 2.0 x 3.6 meters, and video image starts " fuzzy ";
B) in this LED display screen of 2.0 x 3.6 meters, use 2,000,000 three-color LED particles are needed, namely every square metre has 27.7 ten thousand independently three-color LEDs, this is all huge challenge to price, power consumption, heat, consistance, reliability, life-span.
5.0.0 OLED
OLED is a kind of novel display technique, but is still in the experimental phase at present.Be made into several meters even giant-screen of tens meters by OLED and need time.
In sum, the liquid crystal of band black surround frame, rear-projection, plasma all temporarily really cannot realize " seamless " splicing, namely when all producing black square frame after their splicings.
Summary of the invention
