Description

Device for assembling a display panel for stereoscopic images during horizontal/vertical alignment of the display panel

The present invention relates to a display panel assembly technique, and more particularly to a display for stereoscopic images in the case where the horizontal/vertical alignment of the display module and the stereoscopic panel is indeed checked. The stereo panel of the panel provides the technology of assembling to a display module.

The development of information and communication technologies enables multimedia services to support 2D video and sound to a digital terminal. The digital terminal processes text messages, sounds, and images at high speed. It is expected that multimedia services will be developed into three-dimensional information communication services that provide virtual multimedia services in a stereoscopic manner.

In general, a stereoscopic image expressed in three dimensions is based on the stereoscopic principle of the eye. One of the main factors of the stereoscopic effect of the letter is caused by the difference in the eyes, because the distance between the eyes is about 65 mm from each other. According to this, the two eyes see different two-dimensional images. If the two images are transmitted to the brain through the retina, the brain reproduces the depth and sense of reality of the original 3D image by combining the two images with each other. In general, this is called stereo imaging.

The stereoscopic display device is classified into a stereoscopic display device and an autostereoscopic display device depending on the presence or absence of the individual glasses. One disadvantage of stereoscopic display devices is that the viewer must wear special glasses. However, an autostereoscopic display device has an advantage in that a viewer can feel a stereoscopic image by directly viewing the screen without wearing special glasses. In this way, since the autostereoscopic display device solves the drawbacks of the stereoscopic display device, various studies on the autostereoscopic display device have been performed. The autostereoscopic display device is classified into a lenticular type device and a parallax-barrier device.

The lenticular type device means that the viewer views the stereoscopic image by arranging a display panel and fixing a specially manufactured refractor (hereinafter referred to as "convex lens") to the entire surface of the left and right images, respectively. At this time, the display panel is configured such that the left image and the right image of a set of vertical units (red, green, and blue) are alternately arranged in the vertical direction (vertical insertion type).

In addition, the parallax barrier type means that a vertical type of obstacle is disposed in front of the image corresponding to the two eyes, so that the two images synthesized through the mask are viewed by being separated from each other to allow the viewer to Feel the stereo effect.

The stereoscopic image display device includes a stereoscopic panel and a display module, wherein the stereoscopic panel includes the convex mirror lens array or a parallax barrier, and the display module irradiates the image light to the stereoscopic panel. The detailed configuration of the display module and the stereoscopic panel including the parallax barrier, and the detailed configuration of the unit-type stereoscopic image display module for displaying the stereoscopic image in the horizontal and vertical directions is applied to the applicant of the present invention on August 26, 2005. The application was filed in the name and was registered on November 13, 2006. The detailed configuration is disclosed in detail in Korean Patent No. 647517, entitled "Unit Structure Parallax Barrier and Stereoscopic Image Display Device Using the Barrier" (hereinafter referred to as "647517 Patent Invention").

Meanwhile, in the parallax barrier type stereoscopic panel and the convex mirror type stereoscopic panel, the degree of separation of the left image and the right image of the stereoscopic image is affected by the good alignment position with the display module. Accordingly, the assembly accuracy of assembling the panels must be increased.

In addition, according to the related art, before cutting a circular panel or a display module of a circular flat panel, a guiding symbol indicating an alignment position between the stereoscopic panel and the display module is marked. Then, the cut stereoscopic panel and the cut display panel are used to assemble a stereoscopic image display panel. However, there is a problem that the stereo panel and the display module may be misaligned due to a cutting error caused by the cutting step of the circular panel or the display module of the circular flat panel.

In addition, after the circular panel and the display module are cut, if a guiding mark is aligned according to each of the cut stereo panel and the cut display module, a problem occurs. The cost of the display module will increase. In addition, since the TN-LCD (Twisted Nematic Liquid Crystal Display) or TFT (Thin Film Transistor) states included in the stereoscopic panel and the display module are very different from each other, depending on the cutting state, if the value is based on a simple determination Marking the guide mark causes a problem that is misaligned in the same manner as the guide mark is marked in the state of the circular flat panel before cutting the stereo panel and the display module.

Further, if the process of embedding the guide mark to the stereoscopic panel and the display module and the process of assembling the same to each other are performed separately, a problem occurs, and an error generated in the assembly process cannot be avoided.

In order to solve the aforementioned problems, the inventors of the present invention invented the patent No. 0709728 (hereinafter referred to as "709728 Patent Invention") entitled "Equipment and Method for Assembling a Display Panel for Stereoscopic Image", which is based on the applicant's The name was filed on January 20, 2006 and was registered on April 13, 2007. In the "Invention of 709728", alignment of a stereoscopic image and a display module is performed by checking the separation state of the left image and the right image of the actual stereoscopic image state. At this time, the stereo panel and the display module are assembled with each other to reduce the aforementioned alignment error.

However, as disclosed in the 647 517 patent, a display module for a stereoscopic image should be assembled through a device for assembling a display panel, including an alignment requiring alignment of either the horizontal direction and the vertical direction. The module and the unit type stereoscopic image display module requiring alignment in both the horizontal direction and the vertical direction. If the unit type stereoscopic image display module is assembled according to the related art, the alignment of either the horizontal direction and the vertical direction is checked, and then the unit type stereoscopic image display module is rotated to check the other of the horizontal direction and the vertical direction. Alignment. In this case, an alignment error may occur during rotation of the display module.

Further, after checking the alignment of either the horizontal direction and the vertical direction, if the alignment of the other of the horizontal direction and the vertical direction is checked by the rotation, the yield of the assembly process is lowered.

In addition, in the 709,728 patent application, if the number of cameras of an image inspecting unit is increased from only two to four, so that the cameras are inspected in pairs for horizontal and vertical alignment, respectively, the manufacturing cost of the device It will increase, and the practicality of such cameras will decrease. Because of the size of the camera, it may be difficult to set up four cameras in pairs at appropriate positions in the horizontal and vertical directions equal to the distance between the eyes. In this regard, there is a need for another technique to improve the above problems.

It is to be understood that the invention is not intended

At the same time, the following detailed description contains details to provide a thorough understanding of the invention. However, it will be apparent to those skilled in the art that the present invention may be practiced without the details. In some instances, structures and devices of the prior art are omitted in order to avoid ambiguity in the concept of the present invention, or may be shown in the form of a block diagram based on the main functions of each structure and device. In addition, the same component symbols are used throughout the drawings and the description to refer to the same or the like.

1 is a schematic view showing a configuration of a stereoscopic panel and a display module which are assembled to each other by means for assembling a display panel for stereoscopic images.

The display panel for the stereoscopic panel includes a stereoscopic panel 100, and a display module 200 that illuminates the imagery light to the stereoscopic panel 100. Specifically, the stereoscopic panel 100 allows left and right images for stereoscopic images to be selectively displayed on a display panel for stereoscopic images, and may include a parallax barrier (not shown) or a convex mirror. An array of lenses (not shown) wherein the display panel is assembled using equipment for assembling a display panel for stereoscopic images. In addition, if the stereoscopic panel 100 includes a parallax barrier, the parallax barrier may include a TN-LCD. At this time, the display module may include a TFT that irradiates the image light to the TN-LCD.

Hereinafter, as an example, a brief description will be made of the structure in which the stereoscopic panel 100 is a parallax barrier.

2 and 3 are schematic views showing a structure in which a stereo panel is a parallax barrier.

In the parallax barrier type stereoscopic panel 100, as shown in FIGS. 2 and 3, the left image L and the right image R are arranged in the vertical direction Y-Y', and are interleaved in the horizontal direction X-X'. Displayed on the display module 200. In this case, as shown in FIG. 2, the left and right eyes of the user selectively see the left image L and the right image R. At this time, the stereoscopic panel 100 includes a parallax barrier that is repeatedly set at a pitch that the user cannot perceive. Accordingly, the fine alignment error between the stereoscopic panel 100 and the display module 200 can have a very large influence on the stereoscopic image.

Fig. 4 is a schematic diagram showing the configuration of an apparatus for assembling a display panel for stereoscopic image according to the invention of 709728.

As shown in FIG. 4, the apparatus for assembling a display panel for a stereoscopic image according to the 709728 patent includes a position adjusting unit 10, a stereoscopic image signal control unit 20, an image inspecting unit 30, and an assembly unit 40.

The configuration of each unit shown in Fig. 4 will be described with reference to Fig. 1. The position adjustment unit 10 adjusts an assembly position between the stereo panel 100 and the display module 200. The stereo panel 100 allows selective display of left and right images for stereoscopic images. The display module 200 illuminates image light. To the stereo panel 100. In addition, the position adjusting unit 10 includes a jig for supporting the stereo panel 100 and a mounting bracket for supporting the display module 200. Although the position adjustment unit 10 may include a controller that controls the mounts to move any of the mounts in the vertical and horizontal directions, any known control tool may be used as long as the control tool can control the stereo panel 100 and the assembly position of the display module 200 are sufficient.

The stereoscopic image control unit 20 is coupled to the stereoscopic panel 100 and the display module 200 to provide a stereoscopic image signal and a driving control signal, so that the stereoscopic panel 100 and the display module 200 display a stereoscopic image. The stereoscopic image signal includes a left image generated to be seen by one's left eye and a right image generated to be seen by one's right eye. In addition, the driving control signal includes a driving that can control the arbitrarily arranged one of the stereo panel 100 and the display module 200 (for example, if the stereo panel 100 includes the parallax barrier parallax shown in FIGS. 2 and 3, It is the signal of the driver of the obstacle.

In the apparatus for assembling a display panel for stereoscopic image according to the 709728 patent, the image inspecting unit 30 includes two cameras 31 and 32 which are disposed to be spaced apart from each other by a predetermined distance. The distance between the cameras 31 and 32 is equal to the average distance between one person's eyes. Preferably, the distance between the cameras is approximately 65 millimeters. In this case, the two cameras can be divided into a camera L corresponding to one person's left eye and a camera R corresponding to one person's right eye. When the cameras 31 and 32 acquire stereoscopic images displayed on the stereoscopic panel 100 and the display module 200, the image inspecting unit 30 checks the separation state of the left and right images. Accordingly, the cameras 31 and 32 are located at positions where the stereoscopic panel 100 and the display module 200 disposed in the two mounts of the position control unit 20 face each other and overlap each other. Preferably, the cameras 31 and 32 are disposed above the position adjusting unit 10.

In addition, the assembly unit 40 mounts the stereo panel 100 to the display module 200, and after the position adjustment unit 10 adjusts the assembly position of the stereo panel 100 and the display module 200, the image inspection unit 30 checks the same. The separated states of the left image and the right images reach a predetermined reference value or greater. When the left image and the right image are moved to the optimal position by the position adjusting unit 10 in a state where the separated state of the left image and the right image is inspected by the image inspecting unit 30, the assembly is performed. The unit 40 mounts the stereo panel 100 to the display module 200. Accordingly, assembly errors generated during the assembly process can be reduced.

However, if a unit type stereoscopic image display module that requires bidirectional alignment in the horizontal direction and the vertical direction is assembled using the apparatus according to 709728, the following problems occur. In this regard, as an example of the unit type stereoscopic image display module, a unit type stereoscopic image display module according to the invention of 647517 will be briefly described.

5 to 7 are views showing the configuration of a unit type parallax barrier type display module according to the 647517 patent invention.

As shown in Fig. 5, in the unit type parallax barrier type display module, the pixel system is disposed in the horizontal direction X-X' and the vertical direction Y-Y'. In Fig. 5, the pixels of the even-numbered rows corresponding to the double-numbered columns are omitted. The pixels, as shown in FIG. 6, are alternately connected to the two common terminals C1 and C2 and the two segment terminals S1 and S2, and then selectively driven, wherein the vertical or horizontal parallax barrier can be as the seventh The configuration is as shown in (a) and (b) of the figure.

In other words, unlike the general parallax barrier type display module shown in FIGS. 2 and 3, the unit type parallax barrier type display module according to the 647517 patent requires bidirectional alignment in the horizontal direction and the vertical direction.

In the above-described unit type display module requiring bidirectional alignment in the horizontal direction and the vertical direction, in order to check the horizontal alignment state and the vertical alignment state using the existing device such as the 709728 patent invention, the stereo panel and the display should be inspected by checking Executing the module 200 in any of the horizontal direction and the vertical direction, and then rotating the stereo panel and the display module to check the alignment state on the other of the horizontal direction and the vertical direction to perform the assembly process . In this rotating process, alignment errors may occur and the yield of the assembly process may decrease, as described below with reference to FIG.

Fig. 8 is a view showing an example of a stereoscopic image provided by a stereoscopic image signal control unit of a device for assembling a display panel for stereoscopic images.

As shown in FIG. 8, the left image of the stereoscopic image signal provided by the stereoscopic image signal control unit 20 may include an identification mark (eg, "L") representing the left image, and the right image of the stereoscopic image signal may include the representative right. The identification mark of the image (for example, "R"). The stereoscopic image signals provided by the stereoscopic image signal control unit 20 are segmented in the vertical direction in the left and right images as shown in FIG. 8, and are provided in a staggered manner in the horizontal direction, thereby integrally forming an overlapping shape. , where the left image overlaps the right image. In the example in which the image "L" overlaps with "R", as shown in Fig. 8, "L" represents the left image and "R" represents the right image. In the case where the image is actually supplied by the stereoscopic image signal control unit 20, the left and right images which are segmented more finely than the image shown in Fig. 8 are alternately arranged. In this case, when viewed with the naked eye, it is difficult to perceive the left and right image lines in a staggered configuration, and only the "L" and "R" are perceived to overlap each other.

Fig. 9 is a view showing an example of a separation state of the left image and the right image of the image inspecting unit of the apparatus for assembling a display panel for stereoscopic image according to the invention of 709728.

If the position adjustment of the stereo panel 100 and the display module 200 is completed by the position adjustment unit 10, the image obtained by the camera 31 for the left image of the image inspection unit 30 is substantially the same as that of (1) of FIG. The images shown are the same, and the image obtained by the camera 32 for the right image of the image inspecting unit 30 is substantially the same as the image shown in (2) of Fig. 9. That is, after the two cameras 31 and 32 of the image inspecting unit 30 acquire the images displayed by the stereoscopic panel 100 and the display module 200, the position adjustment of the images is completed, and the images are as shown in FIG. In the state of being divided as shown in (1) and (2), the stereoscopic panel 100 and the display module 200 are assembled to each other.

Fig. 10 and Fig. 11 are views showing the positional relationship between two cameras for checking the alignment state of a unit type display module by the image inspecting unit according to the invention of 709728.

In order to mount a general parallax barrier type display module as shown in FIGS. 2 and 3 in a device for assembling a display module for stereoscopic image, the positions of the two cameras 31 and 32 of the image inspecting unit It may be two relative positions (for example, position 501 and position 502) in either the horizontal direction X-X' and the vertical direction Y-Y' (for example, the horizontal direction X-X' in FIG. 10). It passes through the stereo panel 100 and the central portion of the display module 200. In this case, it is possible to check the actual alignment state of either the horizontal direction and the vertical direction of the parallax barrier as shown in FIGS. 2 and 3. Preferably, the distance d between the two cameras 31 and 32 corresponds to the distance between one eye of a person. In general, the distance d is preferably, but not limited to, 65 mm as described above.

Meanwhile, if the unit type stereoscopic image display module is assembled by using the existing device according to the invention of the 709728 patent, the alignment state of either the horizontal direction and the vertical direction must be checked as described above with reference to FIG. 10 (Fig. 10) The middle is the horizontal direction X-X'), and then the other panel is inspected by rotating the stereo panel 100 and the display module 200 by 90° to 270° (clockwise 90° in FIG. 11) (for example) , vertical direction Y-Y'), as shown in Figure 11. In this case, it is necessary to change the positions of the two cameras 31 and 32 of the image inspecting unit 10 from the positions of the corresponding positions 501 and 502 to the positions of the corresponding positions 601 and 602, as shown in Fig. 11.

If the stereo panel 100 and the display module 200 are rotated as described above to check the alignment state of the unit type display module, an alignment error may occur during the rotation as described above, and the assembly process capacity may be caused by individual rotation. And lower. Further, if the design of the image inspecting unit 10 is changed to use four cameras instead of two cameras, the manufacturing cost of the apparatus for assembling the display module for stereoscopic images is increased, and four cameras are appropriately arranged. The position (e.g., the four positions 501, 502, 601, and 602 of Fig. 11) may be limited due to the size of the camera.

Further, instead of rotating the stereoscopic panel 100 and the display module 200 as described above with reference to FIGS. 10 and 11, it is conceivable to rotate the two cameras 31 and 32 by 90 to 270. However, as with the rotation of the stereo panel 100 and the display module 200, the throughput is still reduced by the extra rotation, and the alignment error still occurs due to the inaccurate rotational position of the two cameras.

In order to solve such a problem, the present invention provides an apparatus for assembling a display module for stereoscopic images, which is superior to the 709728 patent invention based on the following principle.

Figure 12 is a schematic diagram showing the core concept of an apparatus for assembling a display module for stereoscopic images in accordance with the present invention.

In order to check the alignment state of the display module for stereoscopic images in either the horizontal direction and the vertical direction, it is not necessary to require two cameras. In Fig. 12, one of the two cameras (camera 32) in the configuration state shown in Fig. 10 is removed, and the other (camera) 31 is only used to check that the stereo panel 100 and the display module 200 are in the horizontal direction. Alignment status on X-X'. In this way, if one of the two cameras is used to acquire a stereoscopic image and check the alignment state of any of the images shown in (1) and (2) of FIG. 9, the other image is regarded as an automatic pair. quasi. For example, if the camera 31 of FIG. 12 is used to acquire the left image L, the camera 31 checks the image as shown in FIG. 9 by acquiring the stereo panel 100 and the display module 200 that display the image as shown in FIG. The alignment state of the left image L shown. In this case, the right image is considered to be an automatic alignment.

This can be achieved when the camera system is placed on either of the horizontal and vertical directions (eg, horizontal direction X-X') based on either of the two relative positions of the central portion (ie, two positions) Located at the same distance based on the central portion, it passes through the stereo panel 100 and the central portion of the display module 200. In addition, since the left image and the right image are selectively seen by the left eye and the right eye, as shown in FIG. 2, even if either of the eyes (for example, the right eye) is seen, the left eye sees For the left image L, it is considered that the right eye only sees the right image R.

Therefore, an image inspecting unit for assembling a device for a stereoscopic image display module according to a preferred embodiment of the present invention can be configured as follows, which can simultaneously check the bidirectional alignment state of the horizontal direction and the vertical direction.

Figure 13 is a diagram showing the arrangement relationship of a camera for an image inspecting unit in an apparatus for assembling a display module panel for stereoscopic images according to a preferred embodiment of the present invention.

Specifically, in the apparatus for assembling a display module panel for stereoscopic images according to the preferred embodiment of the present invention as shown in FIG. 13, the image inspecting unit 10 is equipped with the two cameras 31 and Any one of 32 is disposed on either of the two relative positions 501 and 502 based on the central portion in the horizontal direction XX' of the central portion of the stereo panel 100 and the display module 200 ( The position 501) is shown in FIG. 13 , and the other 32 is disposed on the relative position 601 based on the central portion through the stereo panel 100 and the central portion of the display module 200 in the vertical direction Y-Y′. Provided in any of the 602 and 602 (position 602 in Fig. 13). In this manner, if the two cameras are used, the image inspection unit can synchronously check the stereoscopic panel 100 and the display module 200 by the camera 31 to obtain the stereoscopic image displayed by the stereoscopic panel 100 and the display module 200. The alignment state in the horizontal direction X-X' is as shown in Fig. 12, and both the alignment state of the stereo panel 100 and the display module 200 in the vertical direction Y-Y' are checked by the camera 32. In this case, although two cameras are used as in the related art, it is possible to simultaneously check the alignment state of the display module for stereoscopic images in the horizontal direction and the vertical direction. According to this, the alignment accuracy can be increased, and the productivity of the assembly process can be improved.

In the present invention, although the display module for stereoscopic images is assembled, it may be a unit type display module according to the invention of the 647517 patent, but the display module according to the present invention may be used in the horizontal direction and the vertical direction. One checks the alignment state of the general display module for stereoscopic images. In this case, the advantage lies in the display module for stereoscopic images, which is assembled and placed in the apparatus for assembling the display module without any horizontal or vertical restrictions.

Further, although the stereoscopic panel 100 has been described as a parallax barrier type stereoscopic panel, the stereoscopic panel 100 can be used as a convex mirror-like lens array type stereoscopic panel.

Meanwhile, in the apparatus for assembling a display panel for stereoscopic image according to another embodiment of the present invention, the number of cameras is effectively reduced by the same concept as shown in Fig. 12.

In other words, the image inspecting unit 10 does not necessarily have to contain two cameras in an existing device for assembling a display panel for stereoscopic images. If the positional relationship of the cameras is clearly defined, either of the two cameras can be used to achieve the same effect.

In other words, in this embodiment, the image inspecting unit is assumed to contain a single camera. The single camera is disposed on either of the horizontal direction and the vertical direction of the central portion of the stereo panel 100 and the display module 200 based on the relative positions of the stereo panel 100 and the central portion of the display module 200. Any of them. In this manner, although a single camera is used, the actual alignment of the stereoscopic panel 100 and the display module 200 can be checked as described above with reference to FIG. According to this, the efficiency of using the camera can be multiplied in a state where the existing device is used.

The invention may be embodied in other specific forms without departing from the spirit and essential characteristics of the invention. The above embodiments are therefore to be considered in all respects The scope of the invention is to be determined by a reasonable interpretation of the scope of the appended claims, and all modifications that fall within the equivalent scope of the invention are included in the scope of the invention.

Industrial application

As described above, the present invention can be applied to a plurality of assembly processes in the same manner as the display panel and the stereo panel in the stereoscopic image field, after the actual image alignment state is checked.
