The mechanism provides a display under normal conditions.

Hereinafter, a description will be given of a method of setting the polarizer of the present invention. Referring to FIG. 1A to FIG. 1F , FIG. 1A to FIG. 1F are schematic flowcharts showing different steps of a method for setting a polarizer according to an embodiment of the present invention.

Please refer to FIG. 1A. FIG. 1A is a view showing a polarizer 102 used in the present method. The polarizer 102 includes a polarizer main body 104, a aligning sheet 106 and a connecting portion 108, wherein the polarizer main body 104, the aligning sheet 106 and the connecting portion 108 are integrally formed, and the aligning sheet 106 has a pair of side edges L1 perpendicular to each other. With L2.

The outline of the polarizer main body 104 is not a conventional rectangular outline, and is, for example, a circular arc or a curved shape. In other words, the edge of the polarizer main body 104 is not a straight line, and each point on the edge of the polarizer main body 104 has a tangent. In the present embodiment, the shape of the polarizer main body 104 is circular, but is not limited thereto. In some embodiments, the shape of the polarizer body 104 includes an elliptical shape having a point symmetry. Further, a diagonal line drawn on the polarizer main body 104 is a transmission axis 109 for indicating the polarizer main body 104.

In this embodiment, the pair of sites 112a and 112b may be solid cylinders or bumps, and the pair of sites 112a and 112b have tangent lines T1 and T2, respectively, wherein the tangent lines T1 and T2 are perpendicular to each other. The vacuum tip 114 is disposed to fix the polarizing plate 102 that is aligned.

Referring to FIG. 1C, FIG. 1C is a view of aligning the polarizer 102 on the alignment stage 110. In this stage, the polarizer 102 is disposed on the alignment platform 110 to perform the alignment step. Further, a pair of mutually perpendicular side edges L1 and L2 of the alignment sheet 106 are respectively aligned with the alignment platform 110 such that the pair of side edges L1 and L2 are aligned with one of the alignment platforms 110 and the opposite alignment point 112a.

In some embodiments, the setting method further includes configuring the positions of the pair of sites 112a and 112b to define an extending direction of the penetrating axis 109 of the polarizer body 104 on the alignment platform 110. Taking the 1C diagram as an example, the transmission axis 109 of the polarizer main body 104 is at an angle θ with respect to the horizontal direction of the first C-picture (the angle with respect to the transmission axis 109 in the clockwise direction is based on the horizontal direction). θ), however, when the polarization mechanism of the display panel is changed, for example, when the display panel has different polarization design such that the polarizing plate 102 needs to be adjusted to the polarization direction of the display panel, the transmission axis 109 is on the alignment platform 110. The direction of extension also needs to be adjusted accordingly.

For example, when the polarization design of the display panel is such that the direction of the transmission axis 109 of FIG. 1C needs to be rotated 90 degrees clockwise, the user can change the alignment points 112a and 112b to the alignment platform 110 according to the polarization design. The upper position is such that the penetrating axis 109 is aligned with the polarizer 102 to correspond to the polarized design, as shown in FIG. 1C', wherein the 1C' is a polarized light rotated 90 degrees clockwise in the 1C chart. The slice 102 is aligned. In Fig. 1C', by arranging the positions of the opposite sites 112a and 112b, the polarizer 102 rotated 90 degrees clockwise can be aligned by the alignment of the sites 112a and 112b to define the penetrating axis 109 again. The extending direction on the platform 110, wherein the penetrating axis 109 and the horizontal direction of the 1st C' figure are 90 degrees plus an angle θ (the angle between the penetrating axis 109 and the penetrating axis 109 in the clockwise direction is based on the horizontal direction 90 degrees plus angle θ).

However, the positions of the above reconfigured pairs 112a and 112b are reconfigured. The present invention is merely illustrative and not intended to limit the present invention. Those skilled in the art to which the present invention pertains can flexibly select the relative positional relationship of the opposing points 112a, 112b to define the transmission axis 109 of the polarizer body 104. The direction of extension on the alignment platform 110.

Please refer to both 1D and 1E. FIG. 1D is a view showing the substrate 120 used in the present method, and FIG. 1E is a view in which the polarizer main body 104 is bonded to the substrate 120. At this stage, the polarizer main body 104 is bonded to the substrate 120. Further, the polarizer main body 104 that has been aligned on the alignment stage 110 of FIG. 1C is bonded to the substrate 120, and the polarizer main body 104 and the substrate 120 are bonded to each other. More specifically, in the present embodiment, the polarizer 102 of FIG. 1C is inverted and fixed to the upper surface of the substrate 120 of the first DD to form a case as shown in FIG. Therefore, in the first FIG. 1C, the alignment sheet 106 of the polarizer 102 is relatively located in the upper left corner, and in the first E diagram, the alignment sheet 106 of the polarizer 102 is relatively located in the upper right corner.

Please refer to FIG. 1E and FIG. 1F simultaneously. FIG. 1F is a view of separating the alignment sheet 106 of the polarizer 102. In this stage, the alignment sheet 106 is separated from the polarizer main body 104 such that the polarizer main body 104 and the connecting portion 108 remain on the substrate 120. The method of separating the alignment sheet 106 includes separating the pair by disconnecting the connecting portion 108. Bit slice 106.

In other words, the connecting portion 108 disposed between the polarizer main body 104 and the alignment sheet 106 can be regarded as the sacrificial line 124 of the polarizer 102, so that when the alignment sheet 106 is separated, the riding stitch 124 can be used as a tear line to perform pairing. Separation of the bit slice 106. Further, after the alignment sheet 106 is separated, there is at least one gap between the edge of the remaining portion of the polarizer 102 and the edge of the substrate 120, for example, There is a gap 122 between the edge of the polarizer body 104 and the edge of the substrate 120. After the alignment sheet 106 is separated, the setting of the polarizer main body 104 can be completed.

Further, in FIG. 1F, the combination of the substrate 120 and the polarizer 102 bonded thereto can be regarded as a set of the display panel 100.

Since the display panel 100 will not be able to normally provide a display screen when the transmission axis 109 is offset from the predetermined angle due to the alignment offset, for example, the light emitted from the display panel 100 is offset by the transmission axis 109. It is not possible to exit normally. Through the foregoing arrangement, the transmission axis 109 of the polarizer main body 104 can be disposed at a predetermined angle, so that the display panel 100 can complete the polarization mechanism under normal conditions and provide a display screen.

In addition, the substrate 120 may also be a display module, wherein the display module has an opposite display surface and a backlight surface. The polarizer 102 can be disposed on the display surface or the backlight surface. Taking the 1F diagram as an example, the polarizer 102 can be disposed on its display surface. The vertical projection of the boundary contour formed by the polarizer main body 104 and the connecting portion 108 on the display surface or the backlight surface falls within the display surface or the backlight surface (that is, when the substrate 120 of the first F is a display module). The vertical projection of the boundary contour formed by the polarizer main body 104 and the connecting portion 108 on the substrate 120 may fall on the substrate 120. within).

In summary, when the contour of the polarizer main body 104 is an arc shape or a curved shape, the polarizer 102 may be misaligned due to the rotation when it is aligned. In the embodiment, the polarizer 102 can be aligned with the alignment points 112a and 112b on the alignment platform 110 through the alignment sheet 106, and the polarizer can be disposed after the alignment is completed. The substrate 102 is attached to the substrate 120, and then the alignment sheet 106 is peeled off, so that the polarizer main body 104 can be left on the surface of the substrate. Through such an arrangement, the transmission axis 109 of the circular polarizer body 104 can be disposed at the correct angle in the display panel 100, so that the display panel 100 can normally provide a display screen.

Since the alignment sheet 106 has three sides that can be used for alignment, when the polarizer 102 is When alignment is performed on the alignment platform 110, the number of alignment points 112 on the alignment platform 110 may also be correspondingly increased. For example, the number of alignment points 112 on the alignment platform 110 may be correspondingly increased to three. The alignment step of the polarizer 102 on the alignment platform 110 can be made easier by the increase in the number of the alignment patches 106 and the alignment sites 112. In addition, it should be understood that the number of the above-mentioned aligning patches 106 is merely exemplary, and is not intended to limit the configuration of the polarizer 102 of the present invention. Those skilled in the art to which the present invention pertains can flexibly select the alignment. The number of slices 106. For example, the number of alignment patches 106 can also be two, with each alignment tile 106 still having three sides such that there are six sides available for alignment.

In FIG. 2B, the alignment sheet 106 of the polarizer 102 surrounds the outer edge of the polarizer main body 104, and the side contour of the alignment sheet 106 can be regarded as a rectangle. Similarly, as the number of sides of the alignment sheet 106 increases, the number of alignment points 112 on the alignment platform 110 can also be correspondingly increased, so that the alignment step of the polarizer 102 on the alignment platform 110 can be performed more easily. In this embodiment, the number of the matching points 112 on the alignment platform 110 is four.
