Abstract
The utility model relates to an LED displayer with an imaging surface. The utility model comprises a plurality of box bodies, wherein each box body is provided with an LED installing board, a circuit board and relevant control parts; each LED is respectively connected with the circuit board; the LED displayer also comprises an imaging surface which is arranged in front of the LED installing board. Light rays of the LED are projected onto the imaging surface to form an image, what a user comes into view is no longer a plurality of pixel dots and the granular sensation of a displayed image can be avoided so that a picture is softer and more delicate.
Description
Technical field
The utility model relates to a kind of display technique, more particularly, relates to a kind of light emitting diode indicator with imaging surface.
Background technology
At present, LED display generally all is to arrange red, green, blue (being R, G, B) three-primary color LED or dual base color LED on screen, directly carries out image or literal and shows that people directly see the light that LED sends, such screen is a light-emitting mode, because screen is made up of the pixel of separating, the result is a LED skewness in the screen, and luminous intensity is inconsistent, the mixed light weak effect, have tangible dark space between pixel, display image has tangible particle, and the soft property of picture is poor.
Summary of the invention
A technical matters to be solved in the utility model is, at the defective of prior art, provides a kind of light emitting diode that has imaging surface, and what make that the user sees no longer is luminous one by one LED pixel, and whole screen display is softer.
The technical scheme that the present invention addresses the above problem is, a kind of light emitting diode indicator with imaging surface is provided, comprise a plurality of casings, each casing is provided with light emitting diode installing plate, circuit board and relevant control section, each light emitting diode links to each other with described circuit board respectively, and described display comprises the imaging surface that is arranged on light emitting diode installing plate front.The size of described imaging surface is the display surface size that a plurality of casings are formed.
In the light emitting diode indicator that provides according to the utility model, described imaging surface is a transparent plate.
In the light emitting diode indicator that provides according to the utility model, described imaging surface adopts poly (methyl methacrylate) plate to constitute.
In the light emitting diode indicator that provides according to the utility model, described imaging surface is a translucent sheet.
In the light emitting diode indicator that provides according to the utility model, described imaging surface adopts the ground glass plate to constitute.
In the light emitting diode indicator that provides according to the utility model, described imaging surface is the translucent plate of partially transparent part.
In the light emitting diode indicator that provides according to the utility model, described imaging surface is transparent or semitransparent circular arc panel.
In the light emitting diode indicator that provides according to the utility model, described imaging surface adopts organic glass, ground glass to constitute.
In the light emitting diode indicator that provides according to the utility model, the outside surface of described imaging surface is provided with uniform antireflection microgroove structure.
The utlity model has the light emitting diode indicator of imaging surface, have ray cast that following beneficial effect: LED sends to imaging surface, what the user saw is a smooth screen, makes demonstration softer.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the stereographic map that has the light-emitting diode display of imaging surface in the utility model.
Fig. 2 is the side view that has the light-emitting diode display of imaging surface in the utility model.
Fig. 3 is an another kind of side view with light-emitting diode display of imaging surface in the utility model.
Embodiment
As depicted in figs. 1 and 2, it is for having the stereographic map and the side view of the light-emitting diode display of imaging surface among the embodiment in the utility model, this display comprises a plurality of casings 1, each casing 1 is provided with light emitting diode installing plate 10, circuit board 20 and relevant control section 30, each light emitting diode 100 links to each other with described circuit board 20 respectively, and described display also comprises the imaging surface 40 that is arranged on light emitting diode installing plate 10 fronts.A plurality of light emitting diodes 100 on the installing plate 10 are embarked on journey into the row arrangement, constitute plurality of pixels respectively, and each pixel is made of at least one light emitting diode 100.In Fig. 1, this display screen 10 is a display screen, and each pixel is made of the LED of three kinds of colors of red, green, blue.This display screen also can be single primary colours display screen or dual base color display screen, and in single primary colours display screen, each pixel only is made of a kind of LED of color, and in dual base color LED, each pixel is made of the LED of two kinds of colors.
With reference to shown in Figure 2, LED100 is a direct insertion LED, is welded on the light emitting diode installing plate 10 luminous flat of the common formation of all LED100 by pin.An imaging surface 40 is installed before this light-emitting area, and the ray cast that LED100 sends is to imaging surface 40, thus the formation image.
Fig. 3 is an another kind of side view with light-emitting diode display of imaging surface in the utility model.LED100 among this figure is a paster type light emitting type, this moment light emitting diode installing plate 10 with circuit board 20 integrators, LED100 is attached to the one side of circuit board.
This imaging surface 40 is transparent plates, adopts organic glass to make, and can be translucent flat board also, is made of ground glass.Also can as required this imaging surface 40 be made the translucent flat board of partially transparent part, its material is made of jointly organic glass and ground glass.According to the shape of display, the shape of imaging surface 40 can be arranged to corresponding rectangle, circle or the like.Imaging surface 40 can be arranged to plate shaped, equates that with distance between the light-emitting area also can be arranged to circular arc, the distance between its each several part and the light-emitting area has less variation.On this imaging surface 40, be provided with evenly distributed microgroove, be used for preventing that the light that LED sends is reflected.The shape of this microgroove can be multiple, as straight trough shape, and waveform, pit shape etc.
In display described above, when LED is luminous, ray cast on the whole light-emitting area is to imaging surface 40, thereby formation image, the user sees no longer is one by one luminous point, but the light intensity uniform in-plane has been avoided dark space and tangible particle between the pixel, makes the image of demonstration softer, careful.
