Fig. 4 is the sketch map of structure of the coupling device of existing display panel for stereoscopic image.
According to Fig. 4, comprise substantially according to the coupling device of the display panel for stereoscopic image of existing No. 709728 patents: position adjustment unit 10, three-dimensional image signal control unit 20, image inspection unit 30 and joint unit 40.
With reference to figure 1 and examine the structure shown in Fig. 4, position adjustment unit 10 is adjusted the bonding station of stereoscopic panel 100 and display module 200, wherein, stereoscopic panel 100 is used to make that left-eye image and eye image are optionally shown that display module 200 shines image on the described stereoscopic panel 100 to realize stereo-picture.In addition, position adjustment unit 10 comprises the anchor clamps that are used to support stereoscopic panel 100, is used to support the anchor clamps of display module 200 and is used to adjust at least one described anchor clamps along above-below direction (vertical direction) or the mobile adjustment unit of left and right directions (horizontal direction); Yet, also can optionally use the method for adjustment of any routine, as long as it can adjust the bonding station of stereoscopic panel 100 and display module 200.
The three-dimensional image signal control unit 20 that is connected to stereoscopic panel 100 and display module 200 provides three-dimensional image signal and drive control signal so that it shows stereo-picture.Three-dimensional image signal comprises and is designed to the left-side images of being watched by people's left eye, and is designed to the image right watched by people's right eye.In addition, drive control signal comprises drive signal, can be controlled at the arbitrary structures that can adjust driving in stereoscopic panel 100 and the display module 200 (for example, as shown in Figures 2 and 3 comprise parallax barrier under the parallax barrier situation in stereoscopic panel 100).
In the coupling device according to the display panel for stereoscopic image of No. 709728 patents, image inspection unit 30 comprises two cameras 31,32 that separate with preset distance each other.According to a better embodiment of the present invention, the average distance between two of this preset distance between described two cameras 31,32 and people is identical, is preferably 65mm, but is not limited to this.Described two cameras can be divided into: corresponding to the camera (camera L) of left eye with corresponding to the camera (camera R) of right eye.Image inspection unit 30 is checked the left-side images of stereo-picture and the differentiation situation of image right by taking the described stereo-picture that is presented on described stereoscopic panel 100 and the display module 200 by described camera 31,32.Therefore, camera 31,32 can be arranged on two anchor clamps of position adjustment unit 10, and be positioned on the space at crossover position place of stereoscopic panel 100 and display module 200 and toward each other.Preferably on position adjustment unit 10, but be not limited to this.
In addition, adjust the bonding station of described stereoscopic panel 100 and described display module 200 in position adjustment unit 10, so that the differentiation situation of left-eye image of being checked by image inspection unit 30 and eye image satisfies after the predetermined benchmark, joint unit 40 engages described stereoscopic panel 100 and described display modules 200.Because it is to review and validate under the situation of differentiation situation of left-side images and image right at image inspection unit 30 that joint unit 40 engages the process of stereoscopic panel 100 and display module 200, take place on by position adjustment unit 10 determined optimum positions, therefore can reduce the bonding error that in this process, can occur.
But, utilize above-mentioned coupling device according to No. 709728 patents come in the horizontal direction with the both direction of vertical direction on when all the cell stereo-picture display module of needs adjustment engages, can produce following problem.In order to be explained,, below the cell type stereo-picture display module according to above-mentioned No. 647517 patents is described as an example of cell type stereo-picture display module.
Fig. 5 to Fig. 7 is the diagram of structure of display module that is used to illustrate cell type parallax barrier mode according to No. 647517 patents.
As shown in Figure 5, in the display module of cell type parallax barrier mode, each pixel is arranged according to horizontal direction (X-X ' direction) and vertical direction (Y-Y ' direction), has omitted regularly corresponding to the pixel on the even column of even number line among Fig. 5.Above-mentioned pixel is cross-linked and is optionally driven by two kinds of public terminals (C1 and C2) and two kinds of segment terminal (S1 and S2) as shown in Figure 6, thereby has constituted as (a) of Fig. 7 and the vertical direction (b) or the parallax barrier of horizontal direction.
That is, be different from the display module of general parallax barrier mode as shown in Figures 2 and 3, according to the display module of the cell type parallax barrier mode of No. 647517 patents, it needs the alignment on horizontal direction and the vertical direction both direction.
All need the cell type display module that aligns in the horizontal direction with on the vertical direction both direction for this type of, if utilize the alignment situation of confirming horizontal direction and vertical direction as the existing coupling device of above-mentioned No. 709728 patents, generally speaking, must be earlier in the horizontal direction with vertical direction in one of them direction on confirm the alignment situation of stereoscopic panel 100 and display module 200, then with its rotation, reaffirm the alignment situation of another direction in horizontal direction and the vertical direction, and engage.In above-mentioned rotary course alignment error can take place, therefore reduce the efficient of engaging process.Hereinafter will be elaborated to this in conjunction with the accompanying drawings.
Fig. 8 is an example of the stereo-picture that provided of the three-dimensional image signal control unit by the coupling device of display panel for stereoscopic image.
As shown in Figure 8, the left-side images of the three-dimensional image signal that is provided by three-dimensional image signal control unit 20 can comprise the sign (for example L) of representing left-side images, and the image right of described three-dimensional image signal can comprise the sign (for example R) of representing image right.These stereo-pictures that provided by three-dimensional image signal control unit 20 can be as shown in Figure 8, left-side images and image right vertically are divided, and alternately arrange in the horizontal direction, therefore formed left-side images and image right on the whole and overlapped on together shape.As shown in Figure 8, under the situation of image L and R overlapping, on behalf of left-side images and R, L represent image right.By the three-dimensional image signal control unit 20 actual images that provide, the left-side images and the image right that more accurately are divided by the image more shown than Fig. 8 are staggered.Therefore, when eye-observation, be difficult to recognize left-side images and the image right ground that is staggered, human eye only can think that L and R are overlapped.
Fig. 9 is the diagram that is used to illustrate according to an example of the differentiation situation of the left-side images of the image inspection unit of existing display panel for stereoscopic image coupling device and image right.
If carry out the adjustment of the bonding station of stereoscopic panel 100 and display module 200 by position adjustment unit 10, by the captured image of the left camera 31 of image inspection unit 30 in fact and the image shown in Fig. 9 (1) basic identical, and in fact identical with the image shown in Fig. 9 (2) by the captured image of right camera 32.In other words, take in stereoscopic panel 100 and display module 200 shown images by two cameras 31 of image inspection unit 30 and 32 pairs, when shooting results as shown in Fig. 9 (1) and (2) by under the situation about distinguishing, engage stereoscopic panel 100 and display module 200.
Figure 10 and Figure 11 have illustrated the position relation of using between two cameras that the image inspection unit checks the alignment situation of cell type display module.
When the coupling device of stereo-picture display module engages as shown in Figures 2 and 3 general parallax-barrier type stereoscopic panel and display module, any direction that two cameras 31 of image inspection unit and 32 can be arranged in vertical Y direction and horizontal X direction (this Y and directions X all pass through the center of stereoscopic panel 100 and display module 200) (for example, horizontal direction X-X ' among Figure 10) on about (for example, position 501 and position 502) on these centrosymmetric two positions.Here, can check actual alignment situation on the horizontal direction of parallax barrier as shown in Figures 2 and 3 and any direction in the vertical direction.Preferably, the distance (d) between described two cameras 31 and 32 is corresponding to the distance between people's the eyes.Generally speaking, above-mentioned distance is preferably 65mm, but is not limited to 65mm.
Wherein, if the utilization of cell type stereo-picture display module engages according to the existing coupling device of 709728 patents, as above 10 described with reference to the accompanying drawings, be necessary to check the alignment situation of any direction (the horizontal direction X-X ' among Figure 10) in horizontal direction and the vertical direction, then as shown in Figure 11, by being revolved, stereoscopic panel 100 and display module 200 turn 90 degrees or 270 degree (example that dextrorotation turn 90 degrees has been shown in the accompanying drawing 11) are checked alignment situation on another direction (for example, vertical direction Y-Y ').Here, two of described image inspection unit 10 cameras 31 and 32 position should need from corresponding to the change in location of position 501 and position 502 to as shown in figure 11 position corresponding to position 601 and position 602.
As mentioned above, if stereoscopic panel 100 and display module 200 are rotated to check the alignment situation of described cell type display module, when rotated, will produce alignment error, the efficient of engaging process also will reduce because of additional rotary course.And, if the design of image inspection unit 10 is changed to using four cameras to replace two cameras, the manufacturing cost that is used for the coupling device of described stereo-picture display module so will increase, and because the reason of camera volume, than difficulty in place (for example, four positions 501,502,601 and 602 among Figure 11) go up four cameras of arrangement.
Further, do not consider the method for described rotary stereo panel 100 of above-mentioned Figure 10 and Figure 11 and display module 200, also it is also conceivable that with two cameras 31 and 32 revolve turn 90 degrees or 270 the degree methods.Yet the same with display module 200 with rotary stereo panel 100, because additional rotary course, efficient still is lowered, and because the inaccurate of position of rotation of two cameras still alignment error will take place.
In order to overcome the above problems, the present invention will provide the coupling device of stereo-picture display module, and it improves No. 709729 patents based on following principle.
Figure 12 is the diagram that is used to illustrate according to the key concept of the coupling device of stereo-picture display module of the present invention.
For the horizontal direction of checking described stereo-picture display module and the alignment situation of one of them direction in the vertical direction, might not need two cameras.Among Figure 12, the same with ordered state shown in Figure 10, but removed two magazine cameras (camera 32), had only another camera (camera 31) to be used to check alignment situation on the horizontal direction (X-X ' direction) of stereoscopic panel 100 and display module 200.In this case, have only a camera to be used to carry out the differentiation situation of the arbitrary image in the image shown in stereoscopic shooting and controlling chart 9 (1) and (2) in two cameras, another image is considered to be automatic alignment.For example, if the camera of Figure 12 31 is used to left-side images L is taken, have only the differentiation situation of camera 31 by as shown in Figure 8 stereoscopic panel 100 and display module 200 shown images are taken the left-side images L shown in the controlling chart 9 (1).Here, can think that image right is alignment automatically.
Wherein camera can be positioned at through on any one direction (for example, horizontal direction X-X ') at the center of stereoscopic panel 100 and display module 200 about any one position in these centrosymmetric two positions (being two positions of distance center same distance).And, as shown in Figure 2, left-side images and image right are optionally watched by left eye and right eye, even a glance in office (for example, right eye) under the unheeded situation, if left-side images L can think that image right R is only watched by right eye by left eye according to watching more than certain discrimination.
