Summary of the invention

Technical matters to be solved by this invention is: a kind of simple in structure, 3D eyeglass that contrast is high is provided, and this 3D eyeglass can reduce the light leak rate, improves viewing quality.

For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of 3D eyeglass, comprise sandwich construction from display screen successively toward outside light source direction: following polaroid, lower glass substrate, down nesa coating, down insulation course, down oriented layer, liquid crystal layer, fluid sealant, go up oriented layer, go up insulation course, go up nesa coating, top glass substrate and last polaroid, the absorption axes of described polaroid down and last polaroid is vertical mutually, and each liquid crystal lamella of described liquid crystal layer becomes 90 ° of distortion helical arrangement.

As a kind of preferred scheme, described upward polaroid and following polaroid are the polaroid of high-polarization.

As a kind of preferred scheme, described nesa coating down is plated on the lower glass substrate, the described nesa coating of going up is plated on the top glass substrate, and described insulation course down is printed on the described nesa coating down, and the described insulation course of going up is printed in described going up on the nesa coating.

As a kind of preferred scheme, described nesa coating down and last nesa coating are indium oxide tin film.

After having adopted technique scheme, effect of the present invention is: because a kind of 3D eyeglass, comprise sandwich construction successively from display screen toward outside light source direction: following polaroid, lower glass substrate, following nesa coating, following insulation course, following oriented layer, liquid crystal layer, fluid sealant, last oriented layer, last insulation course, last nesa coating, top glass substrate and last polaroid, the absorption axes of described polaroid down and last polaroid is vertical mutually, each liquid crystal lamella of described liquid crystal layer becomes 90 ° of distortion helical arrangement, therefore, to the eyeglass no power time, because not being only limited to a fixed-direction, the vibration plane of natural light on all directions, evenly do not distribute, therefore, when natural light when eyeglass passes through, filter direction of vibration and the uneven natural light of its absorption axes on the process during polaroid, the direction of vibration polarized light parallel with last polaroid absorption axes sees through, each liquid crystal lamella owing to liquid crystal layer when liquid crystal layer becomes 90 ° of distortion helical arrangement, therefore each liquid crystal lamella just changes the direction of vibration of polarized light gradually, thereby make the direction of vibration of its polarized light parallel with the absorption axes of following polaroid, this moment, polarized light passed through from following polaroid, thereby realized the unlatching of eyeglass; When eyeglass powers up, putting in order of liquid crystal lamella changed, the direction of vibration this moment polarized light parallel with the absorption axes of last polaroid just do not change direction of vibration through liquid crystal smoothly, and because the absorption axes of following polaroid is vertical with the absorption axes of last polaroid, thereby stoped passing through of the direction of vibration polarized light parallel with the absorption axes of last polaroid, so just realized closing to the printing opacity of eyeglass, close very thorough, reduce the light leak rate, the seeing through and close of light forms huge contrast, improve the contrast of eyeglass, increased the quality of watching, solved the problem of ghost image.
