Electronic reader display screenTechnical field
The present invention relates to a kind of electronic reader display screens, more particularly, to a kind of reflective black using Electromagnetic Control progressThe display shown in vain, belongs to display technology field.
Background technology
Could reader be read currently, conventional liquid crystal display needs actively to shine, therefore, long-timeThe light of display screen can cause fatigue to the eyes of reader after reading；For this purpose, many experts and scholars suggest that young student are morePaper reading is carried out, to protect eyesight；But the reading of electronic reading is of low cost, the cost for buying e-book is often paper/ the tens of matter books, and electronic reading is not necessarily to paper, can save a large amount of timber, be good for the environment；
Therefore, there is producer to have developed the display screen of electric ink form, reflective structure is used to carry out display reading, fromAnd the effect similar to printed matter reading is obtained, contribute to the eyes for protecting reader；But due to the display of electric ink formIt is complicated to shield its, and the core technology country does not grasp, can not be applied on a large scale at home.
Invention content
The purpose of the present invention is to overcome the above shortcomings and to provide a kind of simple in structure, easy to use and protection is contributed to readThe electronic reader display screen of reader's eyesight.
The object of the present invention is achieved like this：
A kind of electronic reader display screen, the display screen include display board, and the display board is single by multiple displaysThe matrix structure that identical permutation is constituted, on the display board pressing have a transparent panel, under the display board pressing have an insulation board, it is described absolutelyListrium is arranged with wiring board；
The display unit includes the vertical connecting cylinder being installed on insulation board, and the cross section of the connecting cylinder is rectangleStructure, the connecting cylinder is interior to be equipped with transparent block, is to be provided with hollow cavity in the transparent block, is filled in the hollow cavityThere is dark solution, the cross section of the hollow cavity is rectangular configuration, and white displays block is provided in hollow cavity；The connectionElectromagnet is additionally provided in cylinder, the electromagnet is located at below transparent block；
The white displays block is metal material, and the density of white displays block is less than the density of dark solution；Or instituteIt is non-metallic material to state white displays block, and the density of white displays block is more than the density of dark solution, and dark solution is fourFe 3 O liquid.
A kind of electronic reader display screen of the present invention, the outer wall of the white displays block are vertically provided with plurality of guiding gutter.
A kind of electronic reader display screen of the present invention, be provided on the insulation board passed through for the supply lines of electromagnet it is logicalHole, and the supply lines of electromagnet is connected to after insulation board on wiring board.
Compared with prior art, the beneficial effects of the invention are as follows：
The configuration of the present invention is simple, easy to make and use reflective structure are read, help to protect regarding for readerPower.

Specific implementation mode
Embodiment one：
Referring to Fig. 1 and Fig. 2, a kind of electronic reader display screen of the present invention, the display screen includes display board102, the display board 102 is the matrix structure being arranged to make up by multiple display units 105, and being pressed on the display board 102 hasTransparent panel 101,102 times pressings of the display board have insulation board 103, the insulation board 103 to be arranged with wiring board 104；
The display unit 105 includes the vertical connecting cylinder 1 being installed on insulation board 103, the connecting cylinder 1 it is transversalFace is rectangular configuration, and transparent block 2 is equipped in the connecting cylinder 1, is to be provided with hollow cavity in the transparent block 2, in describedDark solution 3 is filled in cavity body, the cross section of the hollow cavity is rectangular configuration, and it is aobvious that white is provided in hollow cavityShow block 4, the white displays block 4 is metal material, and the density of white displays block 4 is less than dark solution 3, white displays block 4Outer wall be vertically provided with plurality of guiding gutter so that when white displays block 4 moves up and down, dark solution 3 can be smoothCirculation；
Electromagnet 5 is additionally provided in the connecting cylinder 1, the electromagnet 5 is located at 2 lower section of transparent block, the insulation board 103On be provided with the through-hole passed through for the supply lines of electromagnet 5, and the supply lines of electromagnet 5 pass through insulation board 103 after be connected to lineOn road plate 104；
When work, when electromagnet 5 does not work, white displays block 4 floats on 3 top of dark solution, and display screen is shown at this timeFor white, when needing a certain display unit 105 to be shown as black, electromagnet 5 is powered, after white displays block 4 is adsorbed at this timeIt is sunken to 3 lower section of dark solution, is shown as black at this time；
Embodiment two：
The white displays block 4 is non-metallic material, and the density of white displays block 4 is more than dark solution 3, and black is moltenLiquid 3 is ferroso-ferric oxide liquid；At this point, when electromagnet 5 does not work, white displays block 4 is sunken to 3 lower section of dark solution, at this timeDisplay screen is shown as black, and when needing a certain display unit 105 to be shown as white, electromagnet 5 is powered, at this time dark solution 3It is adsorbed downwards, so that white displays block 4 floats on 3 top of dark solution, is shown as white at this time；At this point, can also pass throughControl enters the magnetic force of the current regulation electromagnet 5 of electromagnet 5, so that 3 sinking buoyancy of dark solution is adjustable so that it canShow the font color with certain contrastive colours, such as grey；
In addition：It should be noted that above-mentioned specific implementation mode is only a prioritization scheme of this patent, the skill of this fieldAny change or improvement that art personnel are done according to above-mentioned design, within the protection domain of this patent..
