Description
Technical field
The present invention relates to a kind of stereo-liquid crystal display device.
Background technology
The structure of the graphical phase difference board of current diaphragm type (Film-type patterned retarder) stereo-liquid crystal display device as shown in Figure 1, common liquid crystal panel comprises the array base palte and color membrane substrates (not shown) that are oppositely arranged, the outside of array base palte and color membrane substrates is respectively equipped with the first Polarizer and the second Polarizer, liquid crystal layer (not shown) is accompanied between described array base palte and color membrane substrates, graphical phase difference board is attached in the outside of the second Polarizer, in graphical phase difference board, the height of the inclined region of circle (i.e. the region of quarter-wave plate and 3/4ths wave plates) is slightly less than the pixels tall of normal liquid crystal panel, therefore the linearly polarized light sent from normal liquid crystal panel is by the inclined region of circles different graphical phase difference board, linearly polarized light is made to become left circularly polarized light and right-circularly polarized light, and again by a rotatory polarization plate before entering human eye, the picture entering right and left eyes is separated, old friend's eye can experience 3D (three-dimensional) image.
As shown in Figure 1, between adjacent two inclined regions of circle, there is a transparent region to exist, this transparent region can cause partial line polarized light to become circularly polarized light, therefore this partial line polarized light is also arrived by eye-observation by the rotatory polarization plate before right and left eyes simultaneously, cause the crosstalk (crosstalk) of image, affect 3D display effect.
Summary of the invention
Goal of the invention: for above-mentioned prior art Problems existing and deficiency, the object of this invention is to provide a kind of stereo-liquid crystal display device improving 3D display effect.
Technical scheme: for achieving the above object, the technical solution used in the present invention is a kind of stereo-liquid crystal display device, comprise liquid crystal panel, graphical half-wave plate, 3rd Polarizer and graphical phase difference board, described liquid crystal panel comprises the first substrate and second substrate that are oppositely arranged, the outside of described first substrate and second substrate is respectively equipped with the first Polarizer and the second Polarizer, liquid crystal layer is accompanied between described first substrate and second substrate, described graphical half-wave plate, 3rd Polarizer and graphical phase difference board are attached at the outside of described second Polarizer successively, the angle of the described optical axis of the 3rd Polarizer and the optical axis of the second Polarizer is 2 times of the angle of the optical axis in half-wave plate region and the optical axis of the second Polarizer in described graphical half-wave plate.
The angle of the described optical axis of the 3rd Polarizer and the optical axis of the second Polarizer can be 90 degree, and in described graphical half-wave plate, the angle of the optical axis in half-wave plate region and the optical axis of the second Polarizer can be 45 degree.
In described graphical phase difference board, the height in the inclined region of circle can be slightly less than the height of pixel in described liquid crystal panel.
In described graphical half-wave plate, the height in half-wave plate region can be not less than the height in the inclined region of circle in described graphical phase difference board, and in described graphical half-wave plate, the height in half-wave plate region can be not more than the height of pixel in described liquid crystal panel.
Beneficial effect: the present invention adds the graphical half-wave plate of a slice and a Polarizer between traditional graphical phase difference board and liquid crystal panel, originally the line polarisation not changing into circularly polarized light because of the transparent region between the inclined region of circle is stopped because of the Polarizer added, therefore the crosstalk of image can be reduced, thus improve the 3D display effect of stereo-liquid crystal display device.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing stereo-liquid crystal display device;
Fig. 2 is the structural representation of stereo-liquid crystal display device of the present invention, is wherein the graphical phase difference board and the 3rd Polarizer that increase relative to Fig. 1 in dotted line frame.
In two width figure, the implication of L and R is respectively the pixel that the light the sent pixel entering left eye and the light sent enter right eye.
Embodiment
Below in conjunction with the drawings and specific embodiments, illustrate the present invention further, these embodiments should be understood only be not used in for illustration of the present invention and limit the scope of the invention, after having read the present invention, the amendment of those skilled in the art to the various equivalent form of value of the present invention has all fallen within the application's claims limited range.
As shown in Figure 2, the difference of the prior art shown in the present embodiment and Fig. 1 is: between the second Polarizer and graphical phase difference board, add graphical half-wave plate and the 3rd Polarizer, in this graphical half-wave plate, the optical axis in half-wave plate region and the angle of the optical axis of the 3rd Polarizer and the optical axis of the second Polarizer are respectively 45 degree and 90 degree, therefore by the line polarisation of the second Polarizer through being rotated by 90 degrees behind half-wave plate region in graphical half-wave plate, parallel with the optical axis of the 3rd Polarizer, thus light can normal through the 3rd Polarizer; Then can not be rotated by the transparent region of line polarisation in graphical half-wave plate between half-wave plate region of the second Polarizer, vertical with the optical axis of the 3rd Polarizer, thus light is not by the 3rd Polarizer.In the present embodiment, in graphical half-wave plate, the height in half-wave plate region is equal with the height in the inclined region of circle in graphical phase difference board, therefore not the original light by the transparent region between the inclined region of circle just by the light of the 3rd Polarizer, this causes presenting black (because not having light to pass through) between the inclined region of circle in graphical phase difference board, so the phenomenon of prior art right and left eyes image crosstalk is effectively suppressed, improve the quality of 3D image display.In order to regulate the relation between 3D display quality and brightness, adjust between the height that in graphical half-wave plate, the height in half-wave plate region can justify pixel in the height in inclined region and liquid crystal panel in graphical phase difference board, thus between the height making the transparent region of the height of black region between 0 and the inclined region of circle.
