The present invention relates to a display panel bonding technology, and more particularly, when bonding a stereoscopic panel and a display module of a stereoscopic image display panel, the alignment between the stereoscopic panel and the display module is performed. The present invention relates to a technology for bonding them without alignment errors between the three-dimensional panel and the display module by checking the alignment state.

Advances in information and communication technology have enabled multimedia services that support two-dimensional video and voice to digital terminals that process text, voice, and video at high speeds. It is expected to develop.

In general, a three-dimensional image representing a three-dimensional image is made by the principle of stereo vision through two eyes. An important factor of the three-dimensional effect is the parallax of binocular disparity, or binocular disparity, which appears because the human eyes are about 65 mm apart. Therefore, the left and right eyes each look at a different two-dimensional image, and when these two images are transmitted to the brain through the retina, the brain fuses with each other to reproduce the depth and actual sense of the original three-dimensional image. This is commonly referred to as stereography.

The stereoscopic image display apparatus is largely classified into a stereoscopic stereoscopic image display apparatus and a non-eyeglass type (autostereoscopic) stereoscopic image display apparatus according to whether to wear glasses separately.

Spectacular stereoscopic image display apparatus must bear the inconvenience of observer wearing special glasses, but non-stereoscopic stereoscopic image display apparatus can feel stereoscopic image simply by staring at the screen without wearing the above glasses. Since the shortcomings of the stereoscopic image display device can be solved, much research has been conducted on this. The non-stereoscopic 3D display device is largely classified into a lenticular device and a parallax-barrier device.

In the lenticular method, a display panel is arranged in a vertical direction by alternately arranging a left image and a right image in units of vertical cells (R, G, B) in a vertical direction (vertical interlacing method), and a specially manufactured refractive lens (hereinafter referred to as "lenticular) Lens ”) to separate the left and right images so that a stereoscopic image can be viewed.

In addition, the parallax-barrier method is a method in which a vertical barrier is placed in front of an image corresponding to left and right eyes so that two left and right images synthesized through the barrier are separated and observed to make a stereoscopic feeling. to be.

The stereoscopic image display device includes a stereoscopic panel including the above-described lenticular lens array or parallax barrier and a display module for illuminating image light on the stereoscopic panel, and the specific configuration of the stereoscopic panel and display module including the parallax barrier is It is described in detail in patent application 2005-0078650, filed August 26, 2005 by the applicant and incorporated herein by reference.

In addition, in the parallax barrier type stereoscopic image display device, R, G, and B are sequentially displayed in each pixel according to the image signal instead of R, G, and B units, and stereoscopic images are displayed in pixel units. A configuration of a parallax barrier type stereoscopic image display device, which was filed on December 22, 2004 by the present applicant, claims patent application No. 2004-0110501, which is incorporated herein by reference, and claims priority thereto. And patent application 2005-0127631, filed December 22, 2005.

On the other hand, in the three-dimensional panel according to the parallax-barrier method and the three-dimensional panel according to the lenticular method, the degree of separation between the left image and the right image of the stereoscopic image is influenced by the fine alignment position with the display module, thus joining them.

In addition to the problems, when the state of TN-LCD or TFT included in the three-dimensional panel and the display module is slightly different from each other according to the cutting state, and the guide mark is displayed according to the determined value, the guide mark is displayed in the original state before cutting. In the same manner as in the case of misalignment occurred between them.
