However, in the manufacturing process of the three-dimensional optical film, a little carelessness may cause scratches or holes in the three-dimensional optical film. Therefore, when it is detected that the three-dimensional optical film attached to the display panel has scratches or holes, the damaged three-dimensional optical film must be removed from the display panel, and then a new layer of three-dimensional optical film must be attached again. Optical film. As a result, a large amount of labor costs and material costs will be consumed.

Detailed ways

The arrangement relationship between the display panel and the three-dimensional optical film of the three-dimensional flat-panel display will be described below with reference to FIG. 1 . FIG. 1 is a schematic side view of a three-dimensional flat panel display. Please refer to FIG. 1 , the 3D flat panel display is composed of a display panel 100 and a 3D optical film 180 . The display panel 100 has a first surface 192 and a second surface 194 , and the first surface 192 and the second surface 194 are opposite to each other. The first surface 192 is the display surface of the display panel 100 , and the three-dimensional optical film 180 is disposed (eg attached) on the first surface 192 .

Assuming that the three-dimensional optical film 180 disposed on the display panel 100 is damaged, for example, there is a scratch or a hole, the damage range of the three-dimensional optical film 180 disposed on the display panel 100 can be confirmed first, as shown in FIG. 2 shown. FIG. 2 is a top view of the three-dimensional flat panel display in FIG. 1 . Please refer to FIG. 2 , in this example, the area circled by the mark 110 is the damaged area of the three-dimensional optical film 180 . The damaged area 110 covers two sub-pixels of a pixel in the display panel 100 , the two sub-pixels are the red sub-pixel 102 and the green sub-pixel 104 respectively, and the blue sub-pixel 106 is located within the damaged area 110 outside.

After confirming the damaged area 110 of the three-dimensional optical film 180, the manufacturer can use a laser to irradiate at least one sub-pixel corresponding to the damaged area 110 in the display panel 100, so that the irradiated sub-pixel is permanently disabled. , take Figure 3 as an example. FIG. 3 is a schematic diagram of the display panel of FIG. 2 after being irradiated with laser light. As shown in FIG. 3 , the green sub-pixels 104 corresponding to the damaged area 110 are permanently disabled by laser irradiation. Of course, the manufacturer can also use laser light to irradiate all the sub-pixels corresponding to the damaged area 110 . The above operation is to disable at least one normal sub-pixel in the display panel 100 corresponding to the damaged area 110 to form a dark spot. In this way, the damaged part of the three-dimensional optical film 180 (that is, the damaged area 110 ) will no longer leak light and affect the image quality. Therefore, such a damage repair method can prevent a lot of labor costs and material costs due to scratches or holes in the 3D optical film 180 during the manufacturing process of the 3D flat panel display.

In addition, there are at least two ways to irradiate at least one sub-pixel corresponding to the damaged area 110 in the display panel 100 with laser light, please refer to FIG. 1 again for illustration. The first method is to let the laser pass through the three-dimensional optical film 180 and the first surface 192 of the display panel 100 to irradiate at least one sub-pixel corresponding to the damaged area 110 in the display panel 100, that is, from the display surface of the display panel 100 to irradiate. The second method is to let the laser pass through the second surface 194 of the display panel 100 to irradiate at least one sub-pixel corresponding to the damaged area 110 in the display panel 100 , that is, irradiate from the back of the display panel 100 . Among these two methods, the first method will burn the color resistance of the color filter, which may cause light leakage concerns; while the second method is to deal with the thin film transistors in the sub-pixels, which should belong to better choice.

How to irradiate the TFT with laser light to permanently disable the sub-pixel will be described below. FIG. 4 is an enlarged view of a pixel. In FIG. 4 , the three regions constituted by different oblique lines represent sub-pixels of different colors. In addition, the mark 402 represents the storage capacitor line, the mark 404 represents the pixel electrode, the mark 406 represents the source line, the mark 408 represents the drain electrode of the thin film transistor of the sub-pixel located in the middle, and the mark 410 represents the gate electrode . Assuming that the sub-pixel in the middle is to be permanently disabled, a laser can be used to weld the storage capacitor line 402 corresponding to the sub-pixel in the middle to the corresponding pixel electrode 404 to make the corresponding storage capacitor line 402 welded together. The capacitor line 402 is electrically connected to the corresponding pixel electrode 404 . Marker 412 shows an example of a welding point. Further, the laser can also be used to cut off the gate electrodes of the TFTs located in the middle sub-pixels, so as to avoid the problem of bright lines or dark lines. The mark 414 is an example of a cut-off point.

Since the human eye is most sensitive to green among the three primary colors, followed by red, when using laser light to irradiate sub-pixels, the priority is to permanently disable the green sub-pixels corresponding to the damaged range, and the second is to permanently disable the green sub-pixels corresponding to the damaged range. The red sub-pixel is permanently disabled, and finally the blue sub-pixel corresponding to the damaged area is permanently disabled.

It is worth mentioning that the above-mentioned three-dimensional optical film 180 can be, for example, a retarder, a micro-retarder, a parallax-barrier film or a lenticular film. lens film), there is no limitation here.

Through the above teachings, those skilled in the art can use the above damage repair method to manufacture a 3D flat panel display. Of course, this three-dimensional flat-panel display includes a display panel and a three-dimensional optical film, and the three-dimensional optical film is arranged on the display panel and has a damaged area, and at least one of the damaged areas in the display panel corresponds to the above-mentioned damaged area. Subpixels are permanently disabled.

In addition, through the above teachings, those with ordinary knowledge in this field can summarize some basic operation steps of the method for repairing the damage of the three-dimensional optical film, as shown in FIG. 5 . FIG. 5 is a flowchart of a damage repair method for a three-dimensional optical film according to an embodiment of the present invention. Please refer to FIG. 5, the method includes the following steps: confirming the damaged area of the three-dimensional optical film disposed on the display panel (as shown in step S502); a sub-pixel to permanently disable the above-mentioned sub-pixel (as shown in step S504).

To sum up, the method of the present invention to solve the aforementioned problems is to first confirm the damage range of the three-dimensional optical film disposed on the display panel, and then use laser light to irradiate at least one part of the display panel corresponding to the above damage range. pixel to permanently disable the aforementioned sub-pixels. In other words, at least one normal sub-pixel in the display panel corresponding to the damaged range is disabled to form a dark spot. In this way, the damaged part of the three-dimensional optical film will no longer leak light and affect the image quality. Therefore, the present invention can prevent a large amount of labor cost and material cost due to scratches or holes in the three-dimensional optical film during the manufacturing process of the three-dimensional flat panel display.
