Abstract
An overlapped type double-screen liquid crystal display screen comprises two liquid crystal display screens, two polarized light pieces and a phase difference membrane. The first piece facing stereo image light source is a polarized light piece, the second piece facing stereo image light source is a liquid crystal display screen, the third piece facing stereo image light source is a polarized light piece, the fourth piece facing stereo image light source is a liquid crystal display screen and the fifth piece facing stereo image light source is the phase difference membrane. Five pieces are arranged at the same position in an overlapped mode without gaps. When the overlapped type double-screen liquid crystal display screen is used to display a stereo image, crosstalk value of the displayed stereo image is reduced below 2 percent in comparison with crosstalk value of a displayed stereo in the prior art. The overlapped type double-screen liquid crystal display screen is undifferentiated in appearance, good in optical performance, capable of effectively shielding crosstalk light, and good in stereo image displaying effect.
Description
Technical field
A kind of conversion manifests the eclipsed form double screen liquid crystal display that stereopsis is used.
Background technology
Liquid crystal display in the past is single screen liquid crystal display, adds polarized light piece and phasic difference film, realizes manifesting of stereopsis.
Liquid crystal display in the past, although can realize manifesting of stereopsis, because of the setting of its single screen liquid crystal display, filtering Crosstalk effectively is so that the image that manifests, with tail shadow significantly, sharpness can not reach desired level, thereby can not satisfy the demand that manifests solid, high-resolution image.
Summary of the invention
The purpose of this utility model is by double screen, and the design that the dual-polarization mating plate overlaps so that the utility model is eliminated image tail shadow than existing single more effectively filtering Crosstalk of liquid crystal display that shields, improves sharpness and stereoscopic sensation that image manifests.
The utility model is comprised of liquid crystal display, polarized light piece and phasic difference film, liquid crystal display is two, polarized light piece is two, and the phasic difference film is a slice, order is set be, the first of facing the stereopsis light source is polarized light piece, second is liquid crystal display, and the 3rd is polarized light piece, and the 4th is liquid crystal display, the 5th is phasic difference film, five overlapping gapless settings of coordination.
When using the utility model to manifest stereopsis, develop through double images, can be so that the stereopsis crossfire value that manifests than single stereopsis crossfire value that shields liquid crystal display, be reduced to below 2%.
The utlity model has the outward appearance indifference, optical property is more superior, can effectively shield Crosstalk, makes stereopsis manifest the better characteristics of effect.
Description of drawings
Accompanying drawing is structural representation of the present utility model, also is that summary is with scheming.
Each label is respectively among the figure: (1) polarized light piece, (2) liquid crystal display, (3) polarized light piece, (4) liquid crystal display, (5) phasic difference film.
Embodiment
The utility model is described in further detail now to lift an example:
Embodiment: take 50 mmX50mm liquid crystal displays as example, polarized light piece 1 polarizing axis vertically arranges, and liquid crystal display 2 is the TN type, and polarized light piece 3 polarizing axiss are horizontally disposed with, and liquid crystal display 4 is the OCB type, and phasic difference film 5 slow axis angles are 45 degree.
Claims (1)
1. eclipsed form double screen liquid crystal display, be comprised of liquid crystal display, polarized light piece and phasic difference film, liquid crystal display is two, and polarized light piece is two, the phasic difference film is a slice, it is characterized in that: order is set is, the first of facing the stereopsis light source is polarized light piece, and second is liquid crystal display, the 3rd is polarized light piece, the 4th is liquid crystal display, and the 5th is phasic difference film, five overlapping gapless settings of coordination.
