Description

A kind of multimedia television blackboard
Technical field
The invention belongs to Display Technique field, in particular, provide a kind of multimedia television blackboard, be applicable to the places such as classroom, enterprise's vocational training, TV station's column, have purposes widely.
Background technology
Teacher say while write, student listens while recording the note is the most effective certified teaching means, both pictures and texts are excellent is more conducive to strengthening the space imagining ability of student and the understandability for special graph.Obviously, the teaching method of traditional projector's giant-screen, be difficult to meet above-mentioned requirement, one be the color saturation of projected image, brightness, contrast be difficult to meet the demands, draw the curtain together or turn off houselights and reduce the brightness in classroom, student will cannot see and record the note, thus have influence on teaching efficiency, draw the curtain apart or open houselights, the color saturation of image on projection screen and contrast can reduce rapidly, student can not see screen again, can have influence on teaching efficiency yet; Two is that the light of front projection not only can shake the eye of teacher, causes the temporary blindness of teacher, has not only had potential safety hazard but also can disturb the continuity of teacher's thinking, and be projected in the disappearance that teacher's image with it also can cause projection screen epigraph; Three is that the chalk type being difficult to realize blackboard is on the projection screen write, even if be suitable for hard projection screen, also there is the occlusion issue of hand for projector's light.Adopt back projection to there is the large problem that takes up room, the blackboard obviously for school is also unconformable.Adopt large-sized LCD TV or plasm TV, although can sharpness problems be met, touch-control problem, the eye problem that shakes, but, large-sized LCD TV, plasm TV are obviously too little again relative to international standard 1200x3600 (149 inches), the 1200x4000 (164 inches) of primary school, middle school's blackboard, even adopt the LCD TV of maximum 110 inches, the GB of distance blackboard is also what there is a big difference.There is two problems in too small blackboard, one is that the content of blackboard carrying is very few, can destroy the integrality of courseware content thus, be unfavorable for the integral memory of student, thus teaching efficiency is reduced when row student rear in meeting knows viewing; Two is when meeting the integrality of courseware and be conducive to student's integral memory, can due to the word of courseware, figure too small and in causing after the student of row do not see the content on blackboard and cannot record the note, equally also can have influence on teaching efficiency.In addition, also there is packaging in excessive TV, transport, install, enter and expensive, more high row problems of expense after sale.How to continue, under the prerequisite developing conventional teaching advantage, to incorporate multimedia teaching, improving teaching efficiency undoubtedly by the understandability greatly promoting student.
Summary of the invention
The object of the present invention is to provide a kind of multimedia television blackboard, is the new type blackboard of the advantage unification of melting conventional teaching and multimedia teaching.
Principle of the present invention is the display section being formed a kind of multimedia television blackboard with seamless spliced video wall, to be spraying plating black view film in the surface of seamless spliced video wall increase one side or to paste black view film, one side is the chalk writing board that the clear glass doing anti-dazzle process forms a kind of multimedia television blackboard, use with the blackboard that this makes blackboard of the present invention can work as common available chalk-writing, also can carry out explanation as a kind of multimedia television blackboard to audio frequency and video class courseware to use, the function of the function and multimedia television blackboard that can also merge normal blackboard carries out conbined usage.
