For example, the industry has developed a liquid crystal display device with a curved surface, and the key point of its manufacture is to bend the liquid crystal display module. The bending method is generally to directly apply force to the liquid crystal display module to bend it.

The curved liquid crystal display device can provide users with no loss of image detail or image chroma when sitting in any seat they like to watch a video, and can increase consumers' choices in the flat panel display device market.

Please refer to FIG. 1A and FIG. 1B . FIG. 1A shows a partial top view of a display panel before bending according to an embodiment of the present invention. FIG. 1B shows a cross-sectional view of the display panel along the section line 1-1' according to FIG. 1A. As shown in FIG. 1A and FIG. 1B , the display panel 100 of this embodiment at least includes a pixel layer 120 and a substrate 110 , but is not limited thereto. In other embodiments, a liquid crystal layer 121 can also be arranged 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 several liquid crystal molecules 125, and the liquid crystal molecules 125 can be affected by the electric field generated by the pixel electrode 126 in the pixel layer 120 to change its arrangement state, so as to control the brightness of the display screen of the display panel 100 . In addition, the pixel layer 120 and the substrate 110 of this embodiment are flexible (flexible) pixel layers and flexible substrates.

In this embodiment, the pixel layer 120 has several pixels 122 (only one representative pixel is shown in the figure), and the pixels 122 are arranged in a matrix, but not limited thereto. In other embodiments, the pixel layer 120 includes pixels 122 and other electronic components, such as metal conductive paths or transistors, but not limited thereto. On the other hand, the substrate 110 may include a color filter 112 and several black matrices 114, wherein the color filter 112 has several corresponding regions 112a, for example, the corresponding regions 112a are on the color filter 112, covered with black The matrix 114 surrounds and is coated with the blocks of different colored dyes or materials, and the corresponding area 112a and the black matrix 114 jointly correspond to the pixels 122, that is to say, the black matrix 114 is roughly arranged on the edge of the corresponding area 112a, and black The shape of the matrix 114 and the shape of the corresponding region 112a are substantially the same as that of each pixel 122 , so that the light emitted from the pixel 122 can pass through the corresponding corresponding region 112a to achieve the effect of color filtering. In this embodiment, the corresponding area 112a is roughly rectangular, and the opening formed by the black matrix 114 is also roughly rectangular, but not limited thereto. In addition, in this embodiment, before the pixel layer 120 and the substrate 110 are jointly bent to form a curved display, one side 122a of each pixel 122 is parallel to the side 112b on the same side of the corresponding corresponding region 112a The axial direction A1 of the long side of the substrate 110 has a distance D, wherein the value of the distance D is greater than zero.

Further, please refer to FIG. 2A and FIG. 2B . FIG. 2A shows a partial top view of a display panel after being bent according to an embodiment of the present invention. FIG. 2B is a cross-sectional view of the display panel along the section line 2-2' according to FIG. 2A. As shown in FIG. 2A and FIG. 2B, after the pixel layer 120 and the substrate 110 are jointly bent to form a curved display surface 100a, since the curvature of the pixel layer 120 and the substrate 110 are different, the pixel layer 120 and the color filter The relative position of the light sheet 112 changes after being bent, so that the side 122a of each pixel 122 and the side 112b of the same side of the corresponding corresponding region 112a can be aligned with each other after being bent. In some designs, the corresponding region 122a of the color filter 112 can be substantially centered to the light-transmitting region 122b of the pixel 122 after bending. On the contrary, before bending, the center line of the corresponding region 122a corresponds to the The centerline of the light-transmitting region 122 b of the pixel 122 has an offset of a distance D as shown in FIG. 1B . In other words, after the pixel layer 120 and the substrate 110 are jointly bent to form a curved display surface 100a, the side 122a of the light-transmitting region 122b of each pixel 122 and the side 112b on the same side of the corresponding corresponding region 112a After bending, they are roughly aligned with each other (the centerline of the corresponding region 122a and the centerline of the light-transmitting region 122b of the corresponding pixel 122 will also be roughly aligned), so that the data line layer 123 and the gate line layer 124 in the pixel 122 are bent. Afterwards, it can be completely covered by the black matrix 114, which can prevent the data line layer 123 and the gate line layer 124 from being exposed outside the black matrix 114 after being bent, which will cause a decrease in display brightness and cause color errors and ripples in the displayed image effect problem.

In a specific embodiment, after the pixel layer 120 and the substrate 110 are bent, the corresponding positions of the pixel layer 120 and the substrate 110 at each position are not the same after being deformed due to bending. Therefore, as each pixel The positions of the pixels 122 on the pixel layer 120 are different, so that each pixel 122 has a different degree of offset from its corresponding corresponding region 122a. At the same time, the curvatures 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, in order to make the side 122a of the light-transmitting region 122b of each pixel 122 on the display panel 100 and the side 112b on the same side of the corresponding corresponding region 112a can be approximately equal to each other after bending Alignment, the side 122a of the light-transmitting region 122b of the pixel 122 corresponding to each position of the display panel 100 of this embodiment and the same side of the corresponding corresponding region 112a all have a specific distance value, and the distance value It is obtained by multiplying the value of the distance D by a corresponding parameter.

As shown in FIG. 1C , FIG. 1C shows a partial distribution diagram of the pitch values of the pixels before the display panel of FIG. 1A is bent. In this embodiment, FIG. 1C shows the distribution of spacing values between each pixel 122 in a quarter of the display panel 100 and its corresponding corresponding area 112a, wherein each line segment represents a specific spacing value, and at the same time, each line segment The represented spacing value gradually decreases from the inner line segment L2 to the outer line segment L1. In addition, the distance value of the line segment L2 is the value of the distance D, and the value of the line segment L1 tends to zero (for example, about 3% of the distance D value), each line between the line segment L2 and the line segment L1 The segments all have a corresponding parameter, and the corresponding parameter of each line segment is multiplied by the value of the distance D to be the distance value of this line segment. Decrease, so that the spacing value represented by each line segment gradually decreases from the outer line segment L2 to the outer line segment L1. In addition, taking the quarter of the display panel 100 described in FIG. 1C as an example, the corresponding parameters of the two sides and the top of the quarter of the display panel 100 are zero, that is, the quarter The distance between the pixels 122 corresponding to the two sides and the top side of one of the display panels 100 and the corresponding corresponding regions 112a is zero. Therefore, if a pixel 122 on the line segment L2 is compared with another pixel 122 on the line segment L1, before the two pixels 122 are bent, the side of the pixel 122 on the line segment L2 and its corresponding corresponding area 112a The same side of the pixel 122 on the line segment L1 has a distance D in the axial direction A1 parallel to the long side of the substrate 110, and the same side of the pixel 122 on the line segment L1 and the same side of the corresponding corresponding region 112a are in the axis parallel to the long side of the substrate 110 A1 has a distance of about 0, and the subtraction of the two has a difference D.

In this embodiment, on the premise that the display panel 100 of this embodiment is 55 inches, the pitch value represented by each line segment in FIG. 1C is between 28.99 μm˜39.22 μm, but not limited thereto. In addition, although FIG. 1C discloses a quarter of the distribution of distance values between each pixel 122 in the display panel 100 and the corresponding region 112a, it only needs to divide the distribution of this quarter by the axis 101 of the display panel 100. After mirror copying, the distance value distribution between each pixel 122 and the corresponding area 112a of the other three quarters of the display panel 100 can be obtained, and then the overall distance between each pixel 122 and the corresponding area 112a of the display panel 100 as a whole can be obtained. value distribution.

In detail, the aforementioned quarter of the display panel 100 uses the short side 101a and the long side 101b connecting the axis 101 as mirror surfaces to completely mirror each pixel 122 in the quarter of the display panel 100 According to the distribution of distance values between the corresponding area 112a and the corresponding area 112a, the distance between each pixel 122 and the corresponding area 112a of the other two quarters of the display panel 100 adjacent to the quarter of the display panel 100 described in this embodiment can be obtained. Spacing value distribution. Further, the distance value distribution between each pixel 122 and the corresponding area 112a in the aforementioned quarter of the display panel 100 is mirror-replicated using the short side 101a as a mirror surface, and then the extension line of the long side 101b is used as a mirror surface to reproduce A mirror copy is performed to obtain the distribution of distance values between each pixel 122 of the display panel 100 and the corresponding region 112a located at a quarter of the diagonal. In this way, the value distribution of the distance between each pixel 122 and the corresponding region 112a of the entire display panel 100 can be obtained.

In addition, referring to the descriptions of FIG. 1B , FIG. 1C and FIG. 2B , in this embodiment, after the substrate 110 and the pixel layer 120 are jointly bent, the position of each pixel 122 corresponding to the substrate 110 will shift and change. Roughly speaking, each pixel 122 that mirrors each other along the short side 101a and its extension line can be aligned 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 axis A1 is offset toward the short side 101a and its extension. In other words, the corresponding regions 112a of the color filter 112 on the substrate 110 along the short side 101a and its extension line, which are mirror images of each other, can be separated from the short side along the long side axis A1 of the substrate 110 with respect to the corresponding pixels 122 . The side 101a and its extensions are offset.

Please return to FIG. 1A and FIG. 1B , in this embodiment, the way to form the distance D can be: the side 122a of each pixel 122 extends along the axial direction A1 of the long side parallel to the substrate 110 toward the corresponding corresponding region 112a The sides 112b on the same side are close to and aligned, or, the sides 112b of each corresponding region 112a can also be aligned along the axial direction A1 of the long side parallel to the substrate 110 toward the side 122a on the same side of the corresponding pixel 122 , are not limited to this.

Furthermore, in this embodiment, the distance 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 spacing 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. Wherein, R is the curvature of the curved display surface 100a, T is the thickness of each pixel 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 can be greater than 2500mm, the thickness T of each pixel 122 of the pixel layer 120 and the color filter 112 can be greater than 0.2mm, and the visible size S of the curved display surface 100a can be greater than 32 inches, but Not limited to this. In some embodiments, the thickness T of each pixel 122 and the color filter 112 may be greater than 0.2 mm and less than 0.5 mm, such as 0.3 mm or 0.4 mm, or the visible size S of the curved display surface 100 a may be 42 mm. Between inches and 65 inches, such as 46 inches, 48 inches, 50 inches, 55 inches or 60 inches, but not limited thereto.

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

Please refer to FIG. 3A and FIG. 3B . FIG. 3A shows a partial top view of a display panel before bending according to another embodiment of the present invention. FIG. 3B is a cross-sectional view of the display panel along the section line 3-3' according to FIG. 3A. As shown in FIG. 3A and FIG. 3B , compared with the embodiment described in FIGS. 1A-2B , the display panel 300 of this embodiment does not form a distance D before bending, but the width of the black matrix 114 is further increased. To extend, in detail, the black matrix 114 may have a first black matrix 114a and a second black matrix 114b, and the first black matrix 114a and the second black matrix 114b have a first width a and a second width b respectively, wherein the first width a subtracts the second width b to form a difference, which is the value of the width W further extended by the first black matrix 114 of the black matrix 114 , wherein the difference is greater than zero. In this embodiment, the value of the second width b is approximately between 15um˜30um, but not limited thereto.

Further, in this embodiment, the first black matrix 114a extends along the axis A2 parallel to the short side of the substrate 110, the second black matrix 114b extends along the axis A1 parallel to the long side of the substrate 110, and the first black matrix The first width a of 114a is greater than the second width b of the second black matrix 114b. That is to say, since the width of the second black matrix 114b in this 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 greater than the width of the second black matrix 114b. It should be understood that the second black matrix 114 b in this embodiment is a black matrix 114 with a smaller width among the black matrices 114 extending along the axis A1 parallel to the long side of the substrate 110 . On the other hand, please refer to FIG. 1C together. The width W of the further extended width of the black matrix 114 can be the same as the distribution of the pixel spacing values as shown in FIG. 1C. In other words, if a pixel 122 and For comparison with another pixel 122 located on the line segment L1, before the two pixels 122 are bent, the black matrix of the pixel 122 located on the line segment L2 extending along the axis A2 parallel to the short side of the substrate 110 has an additional width W , and the pixel 122 on the line segment L1 extends along the axis A2 parallel to the short side of the substrate 110 . The extra extended width of the black matrix is 0. Therefore, the subtraction of the two has a difference W.

Further please refer to FIG. 4A and FIG. 4B . FIG. 4A shows a partial top view of a display panel after bending according to another embodiment of the present invention. FIG. 4B is a cross-sectional view of the display panel along the section line 4-4' according to FIG. 4A. As shown in FIG. 4A and FIG. 4B, although the pixel layer 120 and the substrate 110 are offset after being bent, due to the further extended width W of the first black matrix 114a of the black matrix 114, the offset after bending of the pixel 122 can be covered. part of the substrate 110 to avoid the light leakage situation generated when the pixels 122 are shifted.

That is to say, the data line layer 123 and the gate line layer 124 in the pixel 122 can still be completely covered by the first black matrix 114a after being bent, which can prevent the data line layer 123 and the gate line layer 124 from being exposed on the second black matrix.
