The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is elaborated.

A kind of vacuum suction look grain dot matrix display type no material consumption environment friendly blackboard, as Fig. 1, shown in 2, it comprises housing 1, be provided with the blackboard main body of forming with the physical lattice display module 2 of air stream drives by some 3 in the housing 1, some pin holes 4 evenly distribute on the physical lattice display module 2, color dot particle 5 is set in the pin hole 4, physical lattice display module 2 rear portions are provided with and prevent that color dot particle 5 breaks away from the spacing hole 6 of physical lattice display module 2 backward, color dot particle 5 rear portions are provided with and prevent that color dot particle 5 breaks away from the limited post 7 of physical lattice display module 2 forward, housing 1 downside is provided with vacuum generator 8, vacuum generator 8 is provided with vacuum output 9, vacuum output 9 connects housing 1 rear portion and vacuum lettering pen 10 respectively, make between vacuum generator 8 and the pin hole 4 and form passage, vacuum generator 8 one sides are provided with removes writing device 11, switch 12 is set on vacuum generator 8 panels and removes button 13 automatically.

Physical lattice display module 2 is primary colours, and color dot particle 5 is the some look, and what primary colours and two kinds of color contrasts of some look employing were bigger shows that as contrast primary colours adopt matt inferior look, and the some look adopts high reflecting material.
