Embodiment
To combine the accompanying drawing among the utility model embodiment below, the technical scheme among the utility model embodiment is carried out clear, intactly description, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making all other embodiment that obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
The utility model embodiment provides a kind of combination; As shown in Figure 2, comprising: a plurality of display units 101 are provided with post lens 102 at the non-display area of adjacent two said display unit 101 jointing positions 103; Said post lens 102 are planar structure near a side of display unit; Planar structure one side of said post lens 102 and the non-display area of said jointing positions display unit 101 are fitted, and perhaps adopt other structural design, for example; Non-display area at said display unit is provided with a supporting structure, and said post lens 102 are positioned on the said supporting structure and are relative with the non-display area of said display unit.
Need to prove that the non-display area with said display unit 101 said post lens adhere described in the utility model embodiment is meant the surface of the non-display area of said display unit 101 and the corresponding side of beholder.
Concrete, post lens 102 are by transparency material, for example a kind of optical element of processing of various transparent materials such as glass, crystal, plastics.Post lens 102 are planar structure near a side of display unit; A side relative with this planar structure one side can be sphere, also can be aspheric surface, for example; Globoidal structure, male and fomale(M&F) structure; Be other irregular structure etc. perhaps, the utility model does not limit, as long as guarantee to utilize these post lens can reflect the picture that the non-display area at the display unit of jointing positions dwindles.In all embodiment of the utility model, be planar structure with the post lens near a side of display unit, the side that these post lens are corresponding with planar structure one side is that sphere is that example describes.
As shown in Figure 3; The non-display area of adjacent two display units 101 is provided with lens pillar 102; Plane one side of post lens 102 is set to splicing seams with display unit 101 splices everywhere non-display area 103 and fits relatively, the width of plane one side of post lens 102 with equate with the width sum of the non-display area of adjacent two display units 101 of its corresponding applying, exemplary; If adjacent two display units are display unit 1 and display unit 2; In said display unit 1 and said display unit 2 jointing positions, the width of the non-display area of display unit 1 is n1, in said display unit 1 and said display unit 2 jointing positions; The width of the non-display area of display unit 2 is n2; The width of planar structure one side of then said post lens 102 is n1+n2, utilizes post lens 102 to reflect the picture that the jointing positions non-display area dwindles, and is implemented in the purpose of the width of the non-display area that visually reduces display unit 101 jointing positions 103.
Need to prove; The described post lens 102 of above-mentioned embodiment post lens for this reason can be the projection lens; Also can be the lens that make concave cylindrical lens or other type, can be convex lens for wherein certain or certain several lens also, and remaining be the perhaps lens etc. of other type of concavees lens; The utility model does not limit this, and the purpose that only needs these lens of assurance to can be implemented in the width of the non-display area that visually reduces display unit 101 jointing positions 103 gets final product.
As shown in Figure 5; These post lens are made up of the sub-post lens 102 ' of sizes such as a plurality of; The width of each sub-post lens 102 ' is identical with the width sum of non-display area 103 of corresponding adjacent two display unit 101 jointing positions with it in these post lens; The length of post lens with the equal in length of the non-display area of adjacent two said display unit jointing positions of its applying; The length of the post lens that the employing present embodiment is processed is controlled more easily, can carry out freely changing according to the size of combination, adapts to the combination of all size.
Need to prove; The width of each sub-post lens 102 ' can be identical with the width sum of non-display area of corresponding adjacent two display unit 101 jointing positions with it in the described post lens of above-mentioned embodiment; Also can be different; For example, the width of each sub-post lens 102 ' can be less than the width sum of non-display area of corresponding adjacent two display unit 101 jointing positions with it in the post lens; The length of post lens with the equal in length of the non-display area of adjacent two said demonstration display unit jointing positions of its applying, also can less than with the length of the non-display area of adjacent two said demonstration display unit jointing positions of its applying; Sub-post lens 102 ' in the said post lens can be the projection lens; Also can be the lens of concave cylindrical lens or other type; Also can be the combination of above-mentioned several kinds of lens, the purpose that only needs these lens of assurance to can be implemented in the width of the non-display area that visually reduces display unit 101 jointing positions 103 gets final product.
Post lens among the utility model embodiment also can be formed for being superposeed up and down by two-layer lens; As shown in Figure 6; The post lens are formed by being positioned to superpose up and down with the convex lens 1021 that are positioned at concavees lens 1022 tops near the concavees lens of display unit one side 1022; Certainly also be not limited only to this, persons skilled in the art can adopt the lens of other type to superpose up and down to form needed post lens according to actual needs, and the utility model does not limit at this.Need to prove that in the present embodiment, the length of the post lens and method to set up combination and post lens is identical with above-mentioned other embodiment with the setting of width.
Further; The absolute value of the logitudinal magnification of said post lens is less than 1; Realize that the post lens reflect the purpose of reduced image, make the picture that the non-display area of display unit jointing positions dwindles through reflecting of post lens, be implemented in the width of the non-display area that visually reduces the display unit jointing positions.
Because the main design parameters of post lens comprises post lens width d, height H, the radius-of-curvature r of post lens, and refractive index n.Principle according to geometrical optics can know, the object space focal distance f of post lens and as square focal distance f ' can know through following formula.
The computing formula of the imaging of post lens is:
The computing formula of the logitudinal magnification β of post lens is:
can realize that through radius-of-curvature r, refractive index n and the thickness H of post lens reasonable in design the post lens reflect the purpose of the picture that dwindles.
The utility model embodiment also provides a kind of display device, comprises combination.Wherein, said combination is any combination described in the foregoing description.
Display unit described in the utility model embodiment can be display units such as liquid crystal display, OLED display unit, plasma display unit, Electronic Paper display unit.
The utility model embodiment has put forward a kind of combination and display device, at the non-display area of the jointing positions of display unit the post lens is set.Utilize the refraction of post lens, visually realized reducing the width of the non-display area of jointing positions between display unit, improved the display quality of combination, make large-sized display screen when display frame, reduced the sense of isolating of picture.
The above; Be merely the embodiment of the utility model; But the protection domain of the utility model is not limited thereto; Any technician who is familiar with the present technique field can expect changing or replacement in the technical scope that the utility model discloses easily, all should be encompassed within the protection domain of the utility model.Therefore, the protection domain of the utility model should be as the criterion with the protection domain of said claim.
