Abstract
The invention discloses a kind of magnetic blackboard of displaying, and including magnetic display layer, magnetic-particle is white magnetic particle in magnetic display layer；It is black background layer behind magnetic display layer, is hard before magnetic display layer, wear-resisting and transparent writing protective layer；It is provided with after black background layer and is slidably used to magnetropism display layer rear portion be attracted to eliminate the recovery magnetic stripe of display content white magnetic particle.Black matrix adds white displays content identical with traditional blackboard perception, combine that traditional blackboard is comfortable, resolution is high and existing magnetic display board without dust, low-carbon energy-saving is environmentally friendly the advantages of.
Description
Technical field
The present invention relates to teaching aids, particularly a kind of blackboard.
Background technology
Existing magnetic display board all blackens color display content for white background.But traditional blackboard is in comfort level and identification
It is more dominant.Also, existing blackboard and magnetic display board are all without backlight, and upper class hour, classmate farther out are not easy to see at night
It is clear.
The content of the invention
The technical problem to be solved in the present invention is to provide the above problems existing for existing magnetic display board and traditional blackboard.
In order to solve the above technical problems, present invention employs a kind of magnetic blackboard of displaying, including magnetic display layer, magnetism is aobvious
Show that magnetic-particle is white magnetic particle in layer；It is black background layer behind magnetic display layer, be hard before magnetic display layer,
Wear-resisting and transparent writing protective layer；It is provided with after black background layer and is slidably used to attract white magnetic particle to magnetic
Property display layer rear portion is to eliminate the recovery magnetic stripe of display content.
Black background layer is translucent, and even photosphere, luminescent layer and reflector layer are followed successively by behind black background layer；Even photosphere is
Translucent frosted film, luminescent layer are evenly distributed with the hyaline layer of multiple LED lamp beads for surrounding, restore magnetic stripe behind reflector layer.
The device have the advantages that：
Black matrix adds white displays content identical with traditional blackboard perception, combines that traditional blackboard is comfortable, resolution is high and existing
Be magnetic display board without dust, low-carbon energy-saving is environmentally friendly the advantages of.Increased backlight further improves display identification, is farther out
Classmate can also see.
Description of the drawings
Fig. 1 is the structure diagram of the present invention.
In figure：Reflector layer (1), luminescent layer (2), even photosphere (3), black background layer (4), magnetic display layer (5), white magnetic
Property particle (6), writing protective layer (7), magnetic writing pen (8), restore magnetic stripe (9).
Specific embodiment
Embodiment one
As shown in Figure 1, a kind of magnetism blackboard of displaying, including magnetic display layer 5, magnetic-particle is white in magnetic display layer 5
Color magnetic-particle 6；Magnetic display layer 5 is below black background layer 4, is hard before magnetic display layer 5, wear-resisting and transparent
Write protective layer 7；Slidable be used for after white magnetic particle 6 is attracted magnetropism display layer 5 is provided with after black background layer 4
Portion is to eliminate the recovery magnetic stripe 9 of display content.
Present embodiments provide a kind of magnetic display board adds white displays content identical with traditional blackboard perception for black matrix,
Combine that traditional blackboard is comfortable, resolution is high and existing magnetic display board without dust, low-carbon energy-saving is environmentally friendly the advantages of.
Embodiment two
On the basis of embodiment one, black background layer 4 to be translucent, black background layer 4 be followed successively by below even photosphere 3,
Luminescent layer 2 and reflector layer 1；Even photosphere 3 is translucent frosted film, and luminescent layer 2 is evenly distributed with the hyaline layer of multiple LED lamp beads for surrounding,
Magnetic stripe 9 is restored behind reflector layer 1.
Increased backlight further improves display identification in the present embodiment, is that classmate farther out can also see.
Claims (2)
1. magnetic blackboard of displaying, which is characterized in that including magnetic display layer (5), magnetic-particle is white in magnetic display layer (5)
Magnetic-particle (6)；Magnetic display layer (5) below for black background layer (4), be hard before magnetic display layer (5), it is wear-resisting and
Transparent writing protective layer (7)；Be provided with after black background layer (4) it is slidable be used for by white magnetic particle (6) attract to
Magnetic display layer (5) rear portion is to eliminate the recovery magnetic stripe (9) of display content.
2. magnetism blackboard of displaying as described in claim 1, it is characterised in that：Black background layer (4) is translucent, black background
Layer (4) is followed successively by even photosphere (3), luminescent layer (2) and reflector layer (1) below；Even photosphere (3) be translucent frosted film, luminescent layer
(2) hyaline layer of multiple LED lamp beads is evenly distributed with for surrounding, restores magnetic stripe (9) behind reflector layer (1).
