Method for improving the efficiency of three-dimensional optical film

This invention relates to the field of three-dimensional display technology, and more particularly to a method of improving the effectiveness of three-dimensional optical films.

The traditional three-dimensional flat panel display method attaches a three-dimensional optical film on the display panel, so that the two-dimensional display panel can have a three-dimensional display effect.

However, in the manufacturing process of the three-dimensional optical film, a slight inadvertent result in scratching or hole-breaking of the three-dimensional optical film. Therefore, when it is detected that the three-dimensional optical film attached to the display panel is scratched or broken, it is necessary to remove the damaged three-dimensional optical film from the display panel, and then reattach a new three-dimensional optical. film. As a result, a lot of labor costs and material costs will be incurred.

The present invention provides a method for improving the efficiency of a three-dimensional optical film, which can cause a large amount of labor cost and material cost without causing scratches or holes in the three-dimensional optical film in the manufacturing process of the three-dimensional flat display.

The present invention further provides a three-dimensional flat panel display using the above method for improving the efficiency of a three-dimensional optical film.

The present invention provides a method for improving the efficiency of a three-dimensional optical film, comprising the steps of: confirming a damaged range of a three-dimensional optical film disposed on a display panel; and illuminating at least at least a portion of the display panel corresponding to the damaged area by using laser light A sub-pixel to make the above sub-pixels permanently disabled.

The invention further provides a three-dimensional flat panel display comprising a display panel and a three-dimensional optical film. The three-dimensional optical film is disposed on the display panel and has a damaged range. At least one sub-pixel corresponding to the damaged range in the display panel is permanently disabled.

The method for solving the foregoing problem is to first confirm the damage range of the three-dimensional optical film disposed on the display panel, and then irradiate the at least one sub-pixel corresponding to the damaged area in the display panel with the laser light to The above sub-pixels are permanently disabled. In other words, the dark spots are formed by disabling at least one normal sub-pixel in the display panel corresponding to the above-mentioned damaged range. As a result, the damaged portion of the three-dimensional optical film will not leak light and affect the picture quality. Therefore, the present invention can save a lot of labor and material costs due to scratches or holes in the three-dimensional optical film during the manufacturing process of the three-dimensional flat panel display.

The above and other objects, features and advantages of the present invention will become more <RTIgt;

Hereinafter, the arrangement relationship between the display panel of the three-dimensional flat display and the three-dimensional optical film will be described first with reference to FIG. 1 is a side elevational view of a three-dimensional flat panel display. Referring to FIG. 1, the three-dimensional flat panel display is composed of a display panel 100 and a three-dimensional 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.

It is assumed that the three-dimensional optical film 180 disposed on the display panel 100 is damaged, for example, by scratches or holes, and the damage range of the three-dimensional optical film 180 disposed on the display panel 100 can be confirmed first. Shown. Figure 2 is a diagram A top view of a 3D flat panel display. Referring to FIG. 2, in this example, the area circled by the numeral 110 is the damaged range of the three-dimensional optical film 180. The damage range 110 covers two sub-pixels of one 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 Located outside the damaged range 110.

After confirming the damaged range 110 of the three-dimensional optical film 180, the manufacturer can illuminate at least one sub-pixel corresponding to the damaged range 110 in the display panel 100 with a laser light to make the irradiated sub-pixel Permanent disability, as exemplified in Figure 3. 3 is a schematic view of the display panel of FIG. 2 after irradiating the laser light. As shown in FIG. 3, the green sub-pixel 104 corresponding to the damaged area 110 is permanently disabled by illumination of the laser light. Of course, the manufacturer can also use the laser light to illuminate all of the sub-pixels corresponding to the damaged range 110. The above operation is to form a dark spot in the display panel 100 corresponding to at least one normal sub-pixel in the damaged area 110. As a result, the damaged portion of the three-dimensional optical film 180 (ie, the damaged region 110) will not leak light and affect the picture quality. Therefore, such a manner can avoid a large labor cost and material cost due to scratches or holes in the three-dimensional optical film 180 during the manufacturing process of the three-dimensional flat panel display.

In addition, at least two ways of illuminating at least one sub-pixel corresponding to the damaged area 110 in the display panel 100 by laser light are illustrated by referring to FIG. 1 again. In the first aspect, the laser light is transmitted through the three-dimensional optical film 180 and the first surface 192 of the display panel 100 to illuminate at least one sub-pixel corresponding to the damaged area 110 in the display panel 100, that is, from the display panel 100. Display the surface to illuminate. In the second method, the laser light is transmitted through the second surface 194 of the display panel 100 to illuminate at least one sub-pixel corresponding to the damaged area 110 in the display panel 100, that is, from the back surface of the display panel 100. In these two ways, the first way will burn out the color resistance of the color filter, which may make It is a doubt about light leakage; the second method is to treat the thin film transistor in the sub-pixel, which is a better choice.

The following describes how to irradiate a thin film transistor with laser light to permanently disable the sub-pixel. Figure 4 is an enlarged view of a pixel. In Fig. 4, three regions composed of different oblique lines are represented as sub-pixels of different colors. In addition, reference numeral 402 is shown as a storage capacitor line, numeral 404 is shown as a pixel electrode, numeral 406 is indicated as a source line, numeral 408 is indicated as a drain electrode of a thin film transistor in the middle of the sub-pixel, and reference numeral 410 is represented as a gate. Polar electrode. Assuming that the sub-pixel in the middle is permanently disabled, the laser light 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 be welded together. The corresponding storage capacitor line 402 and the corresponding pixel electrode 404 are electrically connected to each other. An indication of a solder joint is shown at 412. Further, it is also possible to use laser light to cut off the gate electrode of the thin film transistor in the middle sub-pixel to avoid the occurrence of a bright line or a dark line. An indication of a cut-off point is shown at 414.

Since the human eye is most sensitive to the green color of the three primary colors, the red color is second. Therefore, when the laser light is used to illuminate the sub-pixel, the green sub-pixel corresponding to the damaged range is preferentially disabled, and the second is corresponding to The red sub-pixel of the damaged range is permanently disabled, and finally the blue sub-pixel corresponding to the damaged range is permanently disabled.

It is worth mentioning that the above-mentioned three-dimensional optical film 180 can be, for example, a retarder film, a micro-retarder, a parallax-barrier film or a lenticular lens film. The lenticular lens film is implemented, and is not limited herein.

With the above teachings, those skilled in the art can use the above methods to create a three-dimensional flat panel display. The three-dimensional flat panel display of course includes a display panel and a three-dimensional optical film, and the three-dimensional optical film system configuration And on the display panel, and having a damaged range, and at least one sub-pixel in the display panel corresponding to the damaged area is permanently disabled.

In addition, with the above teachings, there are some basic operational steps in the art that can be generalized to improve the efficiency of three-dimensional optical films, as shown in FIG. 5 is a flow chart of a method of improving a three-dimensional optical film in accordance with an embodiment of the present invention.
