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.
The present invention relates to a kind of alignment methods of 3D display device, the liquid crystal layer that the display panels of 3D display device comprises the lower glass substrate with thin film transistor (TFT) (TFT) array, the top glass substrate with color filter array (CF) and is arranged between lower glass substrate, in lower glass substrate on the outside surface of back light unit, be pasted with lower light polarizing film; The upper light polarizing film of top glass substrate is pasted with 3D phase difference film.In the lower glass substrate of the display panel of liquid crystal, be formed with the data line supplying data voltage to tft array and the gate line intersected with data line.In the lower glass substrate and top glass substrate of display panels or in lower glass substrate, be formed to the electrode of liquid crystal supply electric field.These electrodes comprise be formed in top glass substrate with or lower glass substrate on be connected with the TFT of tft array and supply the pixel electrode of data voltage and the public electrode for supplying common electric voltage.Display panels is the left image of Alternation Display and right image line by line.Aim at 3D phase difference film to make display panels, the lower glass substrate of display panels is provided with the multiple alignment marks for display panels of the same metal formation being applied to tft array, or in the top glass substrate of display panels, is provided with the multiple alignment marks for display panels of the black matrix" same material formation being applied to CF array.
As shown in Figure 3, display panels alignment mark 30 is formed at the pad place of the periphery of the pel array in the lower glass substrate of display panels 10.Display panels alignment mark 30 is arranged at predetermined intervals.The formation material of this alignment mark 30 can be the grid of tft array or the metal material of source/drain material.Or display panels alignment mark 30 also can be formed at the periphery of the CF array in the top glass substrate of display panels 10.Display panels alignment mark 30 is also arranged at predetermined intervals, and the formation material of this alignment mark 30 can be the black matrix" same material of CF array.Display panels alignment mark 30 is with cross intaglio or other shape compositions.Also form alignment mark 40 at the correspondence position of 3D phase difference film 12 simultaneously.The pattern of alignment mark 40 is consistent with display panels alignment mark 30 and quantity is identical.The alignment mark 40 of 3D phase retardation film has the phase place of λ/4 or 3 λ/4 and is transparent, and λ is wavelength.In order to the alignment mark 40 of the alignment mark 30 with 3D phase difference film that make display panels 10 is aimed at, by using image capture unit (CAM), alignment mark 30 and alignment mark 40 are obtained.CAM is first by a second phase difference film 22 before acquisition alignment mark, and second phase difference film has the phase place of 3 λ/4 or λ/4 and is transparent, and λ is wavelength.Namely second phase difference film 12 is λ/2 or negative λ/2 with the phase differential of the alignment mark of 3D phase difference film.
As shown in Figure 4, when light source irradiates light to display panels 10, liquid crystal panel 10 has the light polarizing film through horizontal linear polarization light, light polarizing film is the light of horizontal direction light polarization, then this polarized light enters the 3D phase difference film 12 of top, alignment mark because of phase difference film 12 has λ/4 phase place, therefore 3D phase difference film 12 allows left light to pass through in an alignment mark B position.And second phase difference film 22 has the phase place of 3 λ/4, only allow right-hand circularly polarized light by, by the left of the alignment mark B of 3D phase difference film 12 only not by second phase difference film 22.Therefore when passing through second phase difference film 22 with CAM, when acquisition image is carried out to the alignment mark B of 3D phase difference film 12, obtain the alignment mark of black as shown in Figure 5.To make on the alignment mark B of 3D phase difference film 12 and display panels the alignment mark 30 on 10 carry out to punctual just easily.When each alignment mark on each alignment mark of 3D phase difference film 12 and display panels on 10, namely display panels 10 is aimed at 3D phase difference film.The light of the horizontal direction of other positions beyond the alignment mark B of phase difference film 12 has left light or right-hand circularly polarized light can pass through by 3D phase difference film 12.
In like manner, the phase place of the alignment mark B of phase difference film 12 can be set to 3 λ/4, and when the phase place of this standard mark B is set to 3 λ/4, the phase place of second phase difference film 22 is set to λ/4.3D phase difference film 12 allows right-hand circularly polarized light to pass through.And second phase difference film 22 has the phase place of λ/4, only allow left light by, be not by second phase difference film 22 by the right-hand circularly polarized light of 3D phase difference film 12.Such CAM is also the alignment mark of black at the image that the alignment mark B by second phase difference film 22 pairs of 3D phase difference film 12 obtains.The light of the horizontal direction of other positions beyond the alignment mark B of phase difference film 12 has left light or right-hand circularly polarized light can pass through by 3D phase difference film 12.
The present invention gives the second embodiment, as shown in Figure 6.With previous embodiment unlike, the present embodiment does not use second phase difference film 22.But use CAM directly to obtain image to the alignment mark of 3D phase difference film and the alignment mark of display panels.Meanwhile, the 3D phase difference film 12 in the present embodiment comprises the lower phase difference film 121 with λ/2 phase place and the upper micro-bit phase difference film 122, λ with λ/4 or 3 λ/4 phase places is wavelength.And the light polarizing film 125 be positioned in the middle of lower phase difference film 121 and upper micro-bit phase difference film 122.Three's adhesive composition becomes 3D phase difference film 12.Wherein, light polarizing film 125 has the light polarization axle through perpendicular linear polarization light.Wherein phase difference film 121 has and the alignment mark one to one of the alignment mark on display panels 10, and the phase place of the alignment mark of lower phase difference film 121 is 0 °.And upper micro-bit phase difference film 122 does not arrange a phase with the alignment mark correspondence position of phase difference film 121 yet.Position as an alignment mark A of phase difference film 121 lower in Fig. 6 is 0 ° mutually and upper micro-bit phase difference film 122 is also 0 ° mutually with the position of alignment mark A correspondence position A '.When light source irradiates light to display panels 10, liquid crystal panel 10 has the upper light polarizing film through horizontal linear polarization light, light polarizing film is the light of horizontal direction light polarization, then this polarized light enters the lower phase difference film 121 of 3D phase difference film 12, because lower phase difference film 121 has λ/2 phase place, the light transmission of vertical direction.And because of the phase place of the alignment mark A of lower phase difference film 121 be 0 °, therefore alignment mark A position light be still horizontal direction through.And when light enters light polarizing film 125, because light polarizing film 125 has the light polarization axle through perpendicular linear polarization light.Therefore the horizontal direction light of alignment mark A position can not be through.And the perpendicular linear polarization light of other positions can carry out through and still for perpendicular linear polarization light.When light enters upper micro-bit phase difference film 122, because upper micro-bit phase difference film 122 has λ/4 or 3 λ/4 phase places, only allow left light or right-hand circularly polarized light through.But, be 0 ° at upper micro-bit phase difference film 122 and the phase place at the alignment mark A correspondence position A ' place of lower phase difference film 121, be still and there is no light transmission.Therefore when carrying out acquisition image with the alignment mark A of CAM to lower phase difference film 121, obtain the alignment mark of black, the same with the effect that Fig. 5 obtains.When the alignment mark on the alignment mark of 3D phase difference film 12 and display panels on 10 is carried out to punctual just easily.When each alignment mark on each alignment mark of 3D phase difference film 12 and display panels on 10, namely display panels 10 is aimed at 3D phase difference film.Because other parts are the same with a upper embodiment, therefore do not describe in detail.
By this programme effectively solve 3D phase difference film and display panel group harmonize immediately time, the problem being difficult to quantize adjustment grade and aim at overlong time of harmonizing by image.
