Specific embodiment
In order to which technical problems, technical solutions and advantages to be solved are more clearly understood, tie below
Accompanying drawings and embodiments are closed, the present invention will be described in further detail.It should be appreciated that specific embodiment described herein is only
To explain the present invention, it is not intended to limit the present invention.
It should be noted that it can be directly another when element is referred to as " being fixed on " or " being set to " another element
On one element or indirectly on another element.When an element is known as " being connected to " another element, it can
To be directly to another element or be indirectly connected on another element.
It is to be appreciated that term " length ", " width ", "upper", "lower", "front", "rear", "left", "right", "vertical",
The orientation or positional relationship of the instructions such as "horizontal", "top", "bottom" "inner", "outside" is that orientation based on the figure or position are closed
System, is merely for convenience of description of the present invention and simplification of the description, rather than the device or element of indication or suggestion meaning must have
Specific orientation is constructed and operated in a specific orientation, therefore is not considered as limiting the invention.
In addition, term " first ", " second " are used for descriptive purposes only and cannot be understood as indicating or suggesting relative importance
Or implicitly indicate the quantity of indicated technical characteristic.Define " first " as a result, the feature of " second " can be expressed or
Implicitly include one or more of the features.In the description of the present invention, the meaning of " plurality " is two or more,
Unless otherwise specifically defined.
It is existing referring to FIG. 1 to FIG. 4, that projection TV curtain provided by the invention is illustrated.The projection TV curtain, packet
Include curtain ontology 2 and the retina texture on curtain ontology 2.Retina texture 3a, 3b, 3c include multiple plane geometry figures
Shape 31, the plane geometric figure 31 at least meet a following conditions: the distance of adjacent plane geometric figure 31 is less than human eye
The product of angular resolution and sighting distance；The width of plane geometric figure 31 is respectively less than the angular resolution of human eye and the product of sighting distance.It needs
It to be illustrated, plane geometric figure 31 includes point 31c, linear 31a, 32a, circle, polygonal figures, linear to include
Straight line, camber line 31a, 32a etc., circle include positive round, ellipse, multifocal null circle etc., and polygon includes triangle, quadrangle, five sides
The concrete shape of shape etc., plane geometric figure 31 is not construed as limiting herein.When plane geometric figure 31 is that closed figures are such as round, more
It is in border shape, the width of frame is the plane geometric figure 31 when being not filled by inside side shape and the plane geometric figure 31
Line thickness；When plane geometric figure 31 is the inside filling of closed figures and the plane geometric figure 31, in solid
Shape, whole width are the line thickness of plane geometric figure 31, such as the width of positive diameter of a circle, quadrangle.
The angular resolution of human eye refers to the resolution capability of human eye, i.e., human eye can two adjacent objects of differentiated differentiation most
The ability of small spacing, and the ability of minimum feature that can be differentiated.The theoretical resolution ability of human eye is about 20 rads, but by
It is actually 1 jiao point to the resolution capability of 5000 nanometers of green-yellow lights, width is small in the distribution and the defect of itself of photosensory cell
It just combines together with background in 1 jiao point of object, can not visually differentiate.Assuming that human eye is sighting distance at a distance from retina texture
D.When sighting distance D is 1m, the minimum spot size (or width of minimum straight line) of resolution described in human eye is the angular resolution and view of human eye
Product away from D, angular resolution α=1 jiao point=0.000291 radian of human eye, when sighting distance D is 1m, the minimum of resolution described in human eye
Point diameter is then 0.000291 radian * 1000mm=0.291mm.Specifically, when sighting distance D is 1m, point 31c, line less than 0.291mm
The plane geometric figures such as 31a, 31b 31 incorporate in the background of curtain ontology 2, and curtain ontology 2 can also incorporate adjacent spacing and be less than
In the plane geometric figure 31 of 0.291mm.More popular says, when sighting distance D is 1m, width is less than the plane geometry of 0.291mm
Perhaps curtain background is plane geometric figure 31 or curtain background of the sightless width more than or equal to 0.291mm to figure 31
Just it is visible.When sighting distance is 2m, the minimum planes geometric figure 31 that human eye can be differentiated is 0.582mm.Plane geometric figure
31 size and spacing is selected according to the size of sighting distance, and specific value is not construed as limiting herein.The size of sighting distance, according to room or
The size in person parlor is selected.The combination of multiple several figures of plane can mutually be echoed with house decoration, not use the projection TV
When curtain, it may have decorative effect makes it have household attribute.
Further, when the width of plane geometric figure 31 be respectively less than human eye angular resolution and sighting distance product when, should
Plane geometric figure 31 can be colored drawing figure, and when due to observing outside the sighting distance, plane geometric figure 31 is invisible, so in the reality
It applies in example, the color of plane geometric figure 31 is not construed as limiting, and can be the combination of random color.When adjacent plane geometric figure 31
Distance be less than human eye angular resolution and sighting distance product when, the background of curtain ontology 2 incorporates in plane geometric figure 31, at this
In embodiment, the color of preferably each plane geometric figure 31 is identical, for white or grey.
Projection TV curtain provided by the invention, compared with prior art, the curtain ontology 2 of projection TV curtain of the present invention
On be provided with retina texture, and the multiple plane geometric figures 31 being spaced apart from each other of stria retinae reason form, the angle point of human eye
Resolution be it is certain, the size of the object that human eye can be differentiated or the limit for differentiating two adjacent objects are related to sighting distance, when
The distance between adjacent plane geometry is less than the angular resolution of human eye and the product of the sighting distance or plane geometric figure 31
Width be respectively less than human eye angular resolution and the sighting distance product when, human eye can not differentiate the plane geometry figure in the sighting distance
Shape 31 can not differentiate two adjacent plane geometric figures 31, i.e., the plane geometric figure 31 and curtain ontology 2 mutually melt
Enter, human eye can not discrimination retina texture and curtain ontology 2, do not influence normal projection when use, the view on curtain ontology 2
Film texture also has certain artistic effect when not in use, and the curtain is made to have household attribute.
A kind of specific embodiment as projection TV curtain provided by the invention referring to FIG. 1 to FIG. 4, curtain sheet
