Abstract
The utility model provides a lens matrix device for removing splicing black frame of television wall, comprising optical lens. The device is characterized in that a lens matrix plain face comprising units of optical lens is arranged in front of the television wall; the device can regulate the separation distance between the lens matrix plain face and the television wall to magnify all the pictures through the corresponding units of lens; the black frame can be right cut off. The utility model has the advantages of convenient manufacturing, convenient installation, and cheap raw materials. The device for removing splicing black frame of television wall can make the pictures behing the black frame coherent, complete, sharp and lifelike.
Description
The utility model relates to a kind of elimination large-screen tv wall picture tube splicing black frame, the video wall picture displayed is linked up become the device of a complete whole picture.
Be to obtain the sensational effect of video wall large scale display, at present, employing be the way that is combined into video wall with a plurality of picture tubes, promptly each display is close to mutually in the display matrix, this has strengthened the picture whole structure of video wall to a certain extent.But because of the influence of picture tube black surround glass bulb thickness and Mounting Earrings, can not between each unit of display matrix, eliminate so-called black surround, thereby, the integrality and the appreciation effect of picture influenced.The patent that two kinds of known elimination black surrounds are arranged, the first " combination screen video wall window frame effect cancellation element " (number of patent application: 88209669.9), its solution is that the trellis reflection box of protruding panel is set at the black surround place, in order to colour and the brightness of reflective viewing screen near the black surround place.Obviously this scheme is can not make picture continuously, just make the black surround place send light and since adopt reflection its brightness of mode and real screen about, left and right sides order is just the opposite, thereby can not play the effect that makes picture continuous; Another is " video wall piece display unit " (number of patent application: 90212394.7), its solution is to add identical with walls display number (or being slightly less than body of wall display number) and the piece display identical with the walls type of display again at the body of wall rear side, and the piece pixel of its generation is led to surface of wall with conduction optical fiber.At first this scheme is because of increasing devices such as piece display and conduction optical fiber, need almost to increase exponentially the equipment investment of video wall, next conducts that optical fiber will pass and effective about 50 millimeters not luminous the scattering between screen of two displays from 3 to 5 millimeters slits between body of wall two displays, the difficulty of its manufacturing process is very big, and the linear relationship of picture also can't guarantee.
The purpose of this utility model is: a kind of elimination video wall splicing black frame is provided, and making the video wall picture displayed is the device of a whole picture that links up.
The method that the utility model is eliminated the video wall black surround is:
Display matrix plane that video wall promptly is made up of each display unit just in face of, be added with the lens matrix that the optical lens unit identical with the video wall element number formed, and each lens of forming lens matrix have identical optical parametric, and distance can be adjusted between lens matrix and the display matrix.
The lens of forming lens matrix can adopt any lens or set of lenses with amplification such as convex lens, meniscus, Fresnel Lenses, fly lens.The size of lens unit equals the size (containing black surround interior) of display unit.
The utility model can change the shape of lens matrix, and to adapt to different appreciation environment, lens unit adopts splicing to form.
With reference to the accompanying drawings and in conjunction with the embodiments the utility model is described in detail.
Accompanying drawing is the structural representation that the utility model is eliminated the device of video wall splicing black frame.
As shown in the figure, the display matrix plane ［ 3 ］ formed by display unit ［ 1 ］ of the utility model and form by lens unit ［ 2 ］ that lens matrix plane ［ 4 ］ constituted.The interplanar distance of display matrix and lens matrix is adjustable.
Regulate the spacing on lens matrix plane ［ 4 ］ and display matrix plane ［ 3 ］, the image of display unit is all amplified by relative lens unit, and black surround is just in time by amputation.
Owing to adopted specification unanimity, lens matrix cheap, simple for production, not only make the cost of device well below the device of existing elimination video wall black surround, and, because there is not pipeline in lens matrix, greatly reduce when installing requirement to mechanical dimension's precision, make this device of Installation and Debugging very easy, and can adjust the size of picture as required at any time.
Claims (2)
1, a kind of lens matrix of being made up of optical lens is eliminated the device of video wall splicing black frame, it is characterized in that: the display matrix plane of forming by display unit [1] [3] and form lens matrix plane [4] by lens unit [2] and constituted, the element number of lens matrix and size equate that with the quantity and the size of display matrix unit two plane distances are adjustable.
2, according to the device of the described elimination video wall of claim ［ 1 ］ splicing black frame, it is characterized in that: the lens unit ［ 2 ］ of forming lens matrix plane ［ 4 ］ can adopt any lens or set of lenses with amplification such as convex lens, meniscus, Fresnel Lenses or fly lens, and each lens unit ［ 2 ］ has identical optical parametric.
