Embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is elaborated.
At first describe in conjunction with Fig. 1 .a and the existing display screen structure of Fig. 1 .b and Fig. 2 .a, the existing seamless spliced scheme of Fig. 2 .b, Fig. 3.
Be the structure of existing display screen and the partial enlarged drawing of frame thereof such as Fig. 1 .a and Fig. 1 .b.Because the restriction of the factors such as display screen technology principle and manufacturing process, all there is the frame 12 of not luminous (namely can not show image) of one fixed width in display screen, when the single display screen shows, 12 stylishnesss that can reduce the display appearance moulding of these frames, can not destroy the integrality of image, but when carrying out the collaborative demonstration of multi-display, these frames will have a strong impact on the effect of demonstration in splicing.
In order to solve the above problems, application number CN200910104850.5 patent disclosure a kind of optical texture that can eliminate piece, such as Fig. 2 .a, Fig. 2 .b and shown in Figure 3.Shown in Fig. 2 .a, Fig. 2 .b, can in certain viewing angle scope, make the sight line 61 of watching that should drop on piece 13 places after optical texture refraction and reflection, fall into picture display face 11, thereby realize utilizing optical means to the blanking of piece.Its concrete grammar: directly over display screen 1, install optical amplifier plate 7 additional, optical amplifier plate 7 be edge thickness than the transparent optical component of middle section thin thickness, and to add the side at edge joint position be the tapered member of reflecting surface 8.Such structure can make near the image of picture display face 11 edge reflect through optical component, so that human eye can be watched in the position that should watch piece 13 image of two display screens of continuous splicing.
Adopt the optical component of Fig. 2 .a structure, situation about can't watch because of the full emission effect of optical amplifier plate lower surface when large viewing angle shows, can occur.As shown in Figure 3, when viewing angle is larger, watch sight line 61 behind superrefraction, can make the angle 73 of itself and optical amplifier plate 7 greater than the cirtical angle of total reflection, thereby make part watch sight line can't fall into image display area owing to total reflection, shade is watched in generation, that is to say that unfavorable effect that the technology of this elimination piece is brought is that the scope of effectively watching of image narrows down.
The defective that can not watch in wide-angle in order to overcome existing optical component, a kind of blanking frame display device shown in Fig. 4 .a and Fig. 4 .b of the utility model structure.Blanking frame display device comprises with the display screen 1 of display bezel 12 and is used for the optical component 2 of blanking display screen frame.
Optical component of the present utility model, its marginal portion 22 comprises convex surface 221, concave curved surface 222 and end face 223.Convex surface 221 and concave curved surface 222 are crooked to frame in the position of the edge of close optical component, convex surface 221 and concave curved surface 222 are the close together near frame place and display image display surface, away from the distant curved surface of frame place and display image display surface.

Watching the sight line knockdown, in the time of as shown in Figure 5, because reflecting the sight line of watching that enters optically denser medium (transparent material) through the optical component upper surface can shine with the lower surface normal direction angle less than the cirtical angle of total reflection in the optically thinner medium (air), namely watch the angle 2222 of sight line and concave curved surface normal 2221 less than the angle of total reflection, so total reflection can not occur, make and watch sight line can successfully drop on the picture display face 11, still can watch good blanking frame image, effectively watch scope thereby can obtain very large demonstration image.
As shown in Figure 6, be the second embodiment of the present utility model, the plane of end face 223 for tilting of the optical component of present embodiment, and the plane of this inclination covers display screen frame 12 fully, through the refraction of optical component upper surface, and total reflection can occur in this dip plane in the sight line 61 of watching at directive frame 12 places, makes and watches sight line still to fall into picture display face 11, be implemented in any viewing location and all can't see display screen frame, namely realize the frame blanking of any viewing location.
Fig. 7 is the 3rd embodiment of the present utility model, the curved surface of end face 223 for tilting of optical component, the end face 223 of optical component adopts curved surface, can make through the sight line areal coverage 111 that falls into picture display face after the reflection less when adopting the plane, thereby the local mirror image distortion of the image that can reduce to watch.
Fig. 8 is the utility model the 4th embodiment, in order to satisfy necessary optical characteristics, the marginal portion 22 of the optical component of this embodiment is thickness larger regional 201, but be that thickness less than marginal portion 22 is than zonule 203 with the Thickness Design of center section 21, on the lower surface of optical component, between two-part different-thickness, adopt mild Transition Design, be mild transitional region 202, adopt the design of present embodiment, can be under the prerequisite that guarantees the required optical characteristics that reaches of optical component, significantly reduce the weight of optical component, this can reduce optical component material cost and so that optical component install and fix easily.
Fig. 9 is the utility model the 5th embodiment, optical component is fixing with display screen 1 by tapered member 3, wherein the end face 223 of the inclined-plane of tapered member 3 and optical component is fitted, tapered member 3 extends a thin slice toward the display screen side, fit in the inner surface of thin slice and display screen side, the oblique surface machining of fitting with the end face of optical component becomes minute surface, and transparent bonding with optical component end face 223, form transparent bonding plane 31, the binding face of display screen side and thin slice inboard adopts bonding, also mechanical connection be can adopt, bonding plane 32 or mechanical connection face 33 formed.Tapered member 3 adopts intensity better and the surperficial metal material that is difficult for oxidation, preferably adopts stainless steel.
