1A and FIG. 1B, FIG. 1A is a partial top view of a display panel before being bent according to an embodiment of the invention. Figure 1B is a cross-sectional view of the display panel of Figure 1A taken along section line 1-1'. As shown in FIG. 1A and FIG. 1B , the display panel 100 of the present embodiment includes at least the pixel layer 120 and the substrate 110 , but is not limited thereto. In other embodiments, a liquid crystal layer 121 may be disposed between the substrate 110 and the pixel layer 120 to form a liquid crystal display device, but not limited thereto, wherein the liquid crystal layer 121 has a plurality of liquid crystal molecules 125, and a liquid crystal. The molecules 125 can be changed in the arrangement state by the electric field generated by the pixel electrodes 126 in the pixel layer 120 to perform brightness control of the display screen of the display panel 100. In addition, the pixel layer 120 and the substrate 110 of the present embodiment are a flexible pixel layer and a flexible substrate.

In this embodiment, the pixel layer 120 has a plurality of pixels 122 (only one representative pixel is shown in the figure), and the pixels 122 are arranged in a matrix manner, but are not limited thereto. In other embodiments, the pixel layer 120 includes a pixel 122 and other electronic components, such as a metal conductive path or a transistor, but is not limited thereto. On the other hand, the substrate 110 may include a color filter 112 and a plurality of black matrices 114. The color filter 112 has a plurality of corresponding regions 112a. For example, the corresponding region 112a is a color filter 112. The black matrix 114 is surrounded by blocks of dyes or materials of different colors, corresponding regions 112a and the black matrix 114 collectively correspond to the pixels 122, that is, the black matrix 114 is disposed substantially at the edge of the corresponding region 112a, and the shape formed by the black matrix 114 and the shape of the corresponding region 112a are substantially equal to each pixel 122. The shapes are the same, so that the light is emitted from the pixel 122, and the color filter effect can be achieved by the corresponding corresponding region 112a. In this embodiment, the corresponding area 112a is substantially rectangular, and the opening formed by the black matrix 114 is also substantially rectangular, but is not limited thereto. In addition, in the embodiment, the pixel layer 120 and the substrate 110 are bent together to form a curved display, and one side 122a of each pixel 122 and the side 112b of the same side of the corresponding corresponding area 112a. The axial direction A1 of the long side of the parallel substrate 110 has a pitch D in which the value of the pitch D is larger than zero.

2A and FIG. 2B, FIG. 2A is a partial top view of the display panel after being bent according to an embodiment of the invention. Figure 2B is a cross-sectional view of the display panel in accordance with Figure 2A taken along section line 2-2'. As shown in FIG. 2A and FIG. 2B, after the pixel layer 120 and the substrate 110 are bent together to form a curved display surface 100a, the pixel layer 120 and the substrate 110 have different bending curvatures, thereby causing the pixel layer 120 to be different. The relative position after bending with the color filter 112 is changed so that the side edges 122a of the same side of each pixel 122 and the side 112b of the same side of the corresponding corresponding area 112a are aligned with each other after being bent. In a partial design, the corresponding region 122a of the color filter 112 after the bending is substantially centered on the light transmissive region 122b of the pixel 122 thereof. In contrast, before the bending, the center line of the corresponding region 122a is opposite thereto. The center line of the light transmitting region 122b of the corresponding pixel 122 has an offset of the pitch D as shown in FIG. 1B. In other words, after the pixel layer 120 and the substrate 110 are bent together to form a curved display surface 100a, the side 122a of the light-transmitting region 122b of each pixel 122 and the side of the same side of the corresponding corresponding region 112a 112b is substantially aligned with each other after bending (corresponding area 122a) The center line and the center line of the light transmitting area 122b of the corresponding pixel 122 are also substantially aligned, so that the data line layer 123 and the gate line layer 124 in the pixel 122 can be completely black after being bent. The matrix 114 is covered to avoid the problem that the data line layer 123 and the gate line layer 124 are exposed outside the black matrix 114 after being bent, causing a decrease in display brightness and causing color errors and ripple effects in the displayed image.

In a specific embodiment, since the pixel layer 120 and the substrate 110 are bent after the pixel layer 120 and the substrate 110 are deformed by bending, the positions corresponding to each other are not the same, and therefore, with each The positions of one pixel 122 on the pixel layer 120 are different such that the degree to which each pixel 122 is offset from its corresponding corresponding region 122a is also different. At the same time, the curvature of the color filter 112 and the pixel layer 120 are also different when bent, so that each pixel 122 has a different degree of offset from the corresponding region 112a. Therefore, in this embodiment, the side edges 122a of the light-transmitting regions 122b of each pixel 122 on the display panel 100 and the side edges 112b of the same side of the corresponding corresponding regions 112a may be approximated to each other after being bent. The one side of the light-transmitting area 122b of the pixel 122 corresponding to each position of the display panel 100 of the present embodiment has a specific spacing value of the same side of the corresponding area 112a. The value of the spacing value is obtained by multiplying the value of the spacing D by a corresponding parameter.

As shown in FIG. 1C, FIG. 1C is a partial distribution diagram showing the pitch values of the pixels before the display panel of FIG. 1A is bent. In the present embodiment, FIG. 1C is a distribution of pitch values of each pixel 122 in the quarter display panel 100 and its corresponding corresponding region 112a, wherein each line segment represents a specific pitch value, and at the same time, each The pitch value represented by the line segment is gradually decreased from the outer line segment L2 to the outer line segment L1. In addition to this, the pitch value of the line segment L2 is the value of the pitch D, and the value of the line segment L1 approaches zero (for example, For the third of the spacing D value, each line segment between the line segment L2 and the line segment L1 has a corresponding parameter, and the corresponding parameter of each line segment is multiplied by the value of the spacing D, that is, the spacing value of the line segment, and simultaneously The corresponding parameter of each line segment is gradually decreased from the line segment of the adjacent line segment L2 to the adjacent line segment L1, so that the interval value represented by each line segment is gradually decreased from the outer line segment L2 to the outer line segment L1. In addition, taking the quarter display panel 100 described in FIG. 1C as an example, the corresponding parameters of the two sides and the top edge of the quarter display panel 100 are zero, that is, the four points. The distance between the pixel 122 corresponding to the two sides and the top edge of the display panel 100 and the corresponding corresponding region 112a of the display panel 100 is zero. Therefore, if a pixel 122 located on the line segment L2 is compared with another pixel 122 located on the line segment L1, the pixels 122 are located on the side of the pixel 122 on the line segment L2 before the bending. The same side of the corresponding area 112a has a pitch D in the axial direction A1 parallel to the long side of the substrate 110, and the side of the pixel 122 on the line segment L1 is parallel to the same side of the corresponding corresponding area 112a. The axial direction A1 of the long side has a pitch of about 0, and the two have a difference D after subtraction.

In this embodiment, on the premise that the display panel 100 of the present embodiment is 55 ,, the pitch value represented by each line segment on FIG. 1C is between 28.99 μm and 39.22 μm, but not limited thereto. In addition, FIG. 1C discloses the distribution of the pitch value of each pixel 122 and the corresponding area 112a in the quarter display panel 100, but only needs to distribute the quarter of the distribution to the axis 101 of the display panel 100. After the mirror copying is performed separately, the spacing value distribution of each pixel 122 of the other three-quarters of the display panel 100 and the corresponding area 112a can be obtained, and it is further known that the entire display panel 100 has each pixel 122 and the corresponding area. The pitch value distribution of 112a.

In detail, the aforementioned quarter display panel 100 points The short side 101a and the long side 101b of the connecting core 101 are mirrored to completely mirror the distribution of the pitch value of each pixel 122 and the corresponding area 112a in the quarter display panel 100, and the phase is obtained. The spacing value distribution of each pixel 122 of the other two quarters of the display panel 100 of the quarter display panel 100 and the corresponding area 112a. Further, the pitch value distribution of each pixel 122 and the corresponding area 112a in the quarter display panel 100 is mirror-reproduced with the short side 101a as a mirror surface, and then the extension line of the long side 101b is used as a mirror surface. A mirror copy is performed again, and the pitch value distribution of each pixel 122 and the corresponding region 112a of the display panel 100 at a diagonal of one quarter thereof can be obtained. Thereby, the distribution of the pitch values of each of the pixels 122 and the corresponding regions 112a as a whole of the entire display panel 100 can be obtained.

In addition, referring to FIG. 1B, FIG. 1C and FIG. 2B, in the embodiment, after the substrate 110 and the pixel layer 120 are collectively bent, the position of each pixel 122 corresponding to the substrate 110 may be shifted. In general, each pixel 122 corresponding to each other along the short side 101a and its extension line can be along the long side of the substrate 110 with respect to its corresponding corresponding region 112a of the color filter 112 on the substrate 110. The axial direction A1 is shifted toward the short side 101a and its extension line direction. In other words, the corresponding region 112a of the color filter 112 of the substrate 110 along which the short side 101a and its extension line are mirror images of each other can be distant from the axial direction A1 of the long side of the substrate 110 with respect to its corresponding pixel 122. The short side 101a and its extension line are offset.

Referring to FIG. 1A and FIG. 1B, in the embodiment, the pitch D may be formed in such a manner that the side 122a of each pixel 122 is along the axial direction A1 of the long side of the parallel substrate 110 to the corresponding corresponding region 112a. The side edges 112b of the same side are aligned and aligned, or the side 112b of each corresponding area 112a is also The side edges 122a on the same side of the corresponding pixels 122 are aligned and aligned along the axial direction A1 of the long side of the parallel substrate 110, and are not limited thereto.

Further, in the present embodiment, the value of the pitch D is greater than: 0.35* (-1.08*10 ^-11 *R ³ +2.2456*10 ^-7 *R ² -0.001714*R+5.6312)*S*T, and The value of the pitch D is less than: 0.4736* (-1.08*10 ^-11 *R ³ +2.2456*10 ^-7 *R ² -0.001714*R+5.6312)*S*T. Here, R is the curvature of the curved display surface 100a, T is the thickness of each of the pixels 122 and the color filter 112, and S is the visible size of the curved display surface 100a. In addition, the curvature R of the curved display surface 100a may be greater than 2500 mm, the thickness T of each pixel 122 and the color filter 112 of the pixel layer 120 may be greater than 0.2 mm, and the visible dimension S of the curved display surface 100a may be greater than 32 吋, But not limited to this. In some embodiments, the thickness T of each of the pixels 122 and the color filter 112 may be greater than 0.2 mm and less than 0.5 mm, for example, 0.3 mm or 0.4 mm, or the visible size S of the curved display surface 100a may be 42.吋~65吋, for example, 46吋, 48吋, 50吋, 55吋 or 60吋, but not limited to this.

In addition, in the present embodiment, the spacing D is obtained by regression analysis of an engineering analysis software. Further, the engineering analysis software may be an LS-dyna analysis software or an Abaqus analysis software, but is not limited thereto.

Please refer to FIG. 3A and FIG. 3B. FIG. 3A is a partial top view of the display panel before being bent according to another embodiment of the present invention. Figure 3B is a cross-sectional view of the display panel of Figure 3A taken along section line 3-3'. As shown in FIG. 3A and FIG. 3B, the display panel 300 of the present embodiment does not form a pitch D before bending, but further increases the width of the black matrix 114, as compared with the embodiment described in FIG. 1A to FIG. Extendingly, in detail, the black matrix 114 may have a first black matrix 114a and a second black matrix 114b, the first black matrix The first black layer 114b and the second black matrix 114b have a first width a and a second width b, respectively, wherein the first width a minus the second width b forms a difference, and the difference is further the first black matrix 114 of the black matrix 114. The value of the width W that extends out, where the difference is greater than zero. In this embodiment, the value of the second width b is between approximately 15 um and 30 um, but is not limited thereto.

Further, the first black matrix 114a of the present embodiment extends along the axial direction A2 of the short side of the parallel substrate 110, and the second black matrix 114b extends along the axial direction A1 of the long side of the parallel substrate 110, and the first black matrix The first width a of the 114a is greater than the second width b of the second black matrix 114b. That is, since the width of the second black matrix 114b of the present embodiment is not increased, only the width of the first black matrix 114a needs to be increased, so the width of the first black matrix 114a is larger than the width of the second black matrix 114b. It should be understood that the second black matrix 114b of the present embodiment is a black matrix 114 having a small width among the black matrices 114 extending along the axial direction A1 of the long side of the parallel substrate 110. On the other hand, referring to FIG. 1C together, the width W of the width of the black matrix 114 further extending may be the same as the distribution of the pitch values of the pixels as shown in FIG. 1C, in other words, taking a pixel located on the line segment L2. 122 is compared with another pixel 122 located on the line segment L1, the black matrix of the pixel 122 on the line segment L2 extending along the axial direction A2 of the short side of the parallel substrate 110 before the bending of the two pixels 122. There is an additional width W, and the pixel 122 on the line segment L1 has a width of 0 extending further along the black matrix extending in the axial direction A2 of the short side of the parallel substrate 110, so that the two have a difference W after subtraction.

4A and FIG. 4B, FIG. 4A is a partial top view of the display panel after being bent according to another embodiment of the present invention. Figure 4B is a cross-sectional view of the display panel in accordance with Figure 4A taken along section line 4-4'. As shown in FIG. 4A and FIG. 4B, although the pixel layer 120 and the substrate 110 are bent, The offset, but due to the width W of the first black matrix 114a of the black matrix 114 extending further, may cover the portion of the substrate 122 that is deflected after the pixel 122 is bent to avoid the light leakage condition generated when the pixel 122 is shifted.

That is to say, the data line layer 123 and the gate line layer 124 in the pixel 122 can be completely covered by the first black matrix 114a after being bent, so that the data line layer 123 and the gate line layer 124 are prevented from being exposed.
