Description
Technical field
The utility model relates to large-scale (outdoor or indoor) LED image display screen especially can bore hole be watched large-scale (outdoor or indoor) LED image display screen of stereopsis.
Background technology
Adopt LED to form that large-scale image display screen is used for advertisement or stage background or as the technology of big assembly landscaping now by ripe and adopted widely.Problem is that these screens all can only the display plane image.
A kind of stereoscopic photograph that utilizes the cylindricality grating is arranged in the market, and what have does finely, and not only third dimension is very strong, and angle of visibility is also big, and the variation of viewing distance is also had suitable adaptability.Watch this stereoscopic picture plane need not carry extraordinary glasses, bore hole just watches.This stereoscopic photograph, be that the light that the eyes that utilize the cylindricality grating adjacent image point stringer can be throwed the characteristic of two eyes to about the beholder and people are respectively penetrated fork-like farm tool used in ancient China to different directions has optionally characteristics, allow two width of cloth that angle differs (or the several) similar image that has after treatment about the beholder two to see respectively, thereby produce third dimension.But these use the stereoscopic photograph of three-dimensional cylindricality original screen panel or film to be difficult to size is done greatly, if do very greatly, also are very difficult received on technology and on the size of plate or film; In addition, they can only show still image, if show that dynamic image must use TV, do not say that large scale stereoscopic TV cost will increase, and require people to wear extraordinary glasses and see that tridimensional advertisement in the street also is very unpractical.
Summary of the invention
The purpose of this utility model is the large LED image display screen that provides a kind of bore hole to watch stereopsis.
The technical solution of the utility model adopts large-scale the shown static state is made up of LED and the screen of dynamic color image.A kind of bore hole is watched the large LED screen of stereopsis, it is characterized in that, and the equal ovalize in the top of red light emitting diodes, blue LED, green LED, longitudinally linear array is formed a luminescence unit; There are several luminescence units to be embedded on the plane of delineation plate of reflective black not; The top of luminescence unit is concordant with plane of delineation plate surface;
Leaded light polarisation piece cross section is a square, and length of side N is identical with the line-spacing P of luminescence unit; Its four sides are by the not reflective plastic wraps of black, and the internal material that is surrounded by the not reflective plastics of black is the big polyester (PET) of the good refractive index of transparency; Leaded light polarisation piece is divided into the top curved surface of column towards the leaded light polarisation piece on a left side and the top curved surface of column leaded light polarisation piece towards the right side;
Be provided with not reflective black positioning and guiding wall in the both sides of each luminescence unit; Leaded light polarisation piece is fixed between two adjacent positioning and guiding walls; The line-spacing M of leaded light polarisation piece is identical with the line-spacing P of luminescence unit;
The leaded light polarisation piece top curve surface garden arc that is provided with on each luminescence unit in each luminescence unit file is towards all identical, and the top curve surface garden arc of the leaded light polarisation piece that is provided with on each luminescence unit in its adjacent luminescence unit file is towards opposite with it.
See from macroscopic view and its garden, top arc all is installed on each luminescence unit that each file luminescence unit lists on the whole LED image display screen towards identical leaded light polarisation piece, and its garden, top arc is installed towards the leaded light polarisation piece opposite with it on each luminescence unit of its adjacent luminescence unit file, this just forms a kind of large size column mirror grating that is applicable to the large LED screen that is equivalent to each luminescence unit is regarded as a pixel.The large LED screen of this structure has has the similar image of certain subtense angle to throw respectively to left and right two of the interior beholder of certain limit distance treated two width of cloth, thereby makes it produce relief effect under the bore hole situation.
The utility model has the advantages that and under beholder's bore hole situation, to show stereo-picture, and be applicable to large-scale (outdoor or indoor) LED color image display screen curtain.
