It should be noted here that the contact area of the spacer with the substrate refers to the area of the substrate occupied by the spacer when it is disposed (or formed) on the corresponding substrate. For example, when the spacer is a linear cylinder, the top surface and the bottom surface thereof are perpendicular. The projected area is substantially the same such that its area of contact with the substrate is equal to the vertical projected area of the top/bottom surface. When the spacer is a cylindrical or trapezoidal shape with a wide bottom and a narrow top, the vertical projection area of the top surface is smaller than the vertical projection area of the bottom surface, and the wide bottom of the spacer is in contact with the substrate such that the contact area with the substrate is equal to the wide bottom surface.

The shape of the spacer is not limited to the foregoing, and may be other polygons such as a triangle, a square or other suitable shape. Furthermore, the foregoing spacers are in contact with the substrate, and the spacers may be in direct contact with the inner surface of the substrate, or the inner surface of the substrate may have components required for manufacturing the inner surface of the substrate or required for manufacturing the display panel. At least one film layer, therefore, the contact of the spacer with the inner surface of the substrate also includes the spacer being in contact with at least one film layer on the inner surface of the substrate.

In another embodiment, the at least one of the first spacers 141 and the second spacers 142 may be selected as the at least one main spacer 140a and the at least one spacer 140b. The sum of the contact areas of the main spacers 140a and the second spacers 140b with the first substrate 110 and the second substrate 120 is preferably less than 0.6% of the unit area and greater than 0% (ie, 0% < primary or secondary gap) The ratio of the material is <0.6%), and the ratio of the primary or secondary interstitial is no unit. Preferably, the total contact area of the main spacers 140a with the first substrate 110 or the second substrate 120 is less than 0.1% of the unit area, and is greater than 0% (ie, 0% < main spacer ratio <0.1%). The sum of the contact areas of the spacers 140a with the first substrate 110 or the second substrate 120 is smaller than the unit area. 0.6%, and greater than 0% (ie 0% < secondary interstitial ratio <0.6%). A description of the relationship between the unit area and the spacer ratio can be referred to the foregoing.

FIG. 3A and FIG. 3B are schematic diagrams showing the interlocking action of the spacers when the display panel of the present embodiment is bent. As shown in FIG. 3A and FIG. 3B, the first spacer 141 and the second spacer 142 are disposed on the first substrate 110 and the second substrate 120 by the staggered manner (or the staggered manner). When the panel 10 is bent, the spacing between the first spacers 141 and the second spacers 142 disposed in parallel with at least one of the first spacers 141 and the second spacers 142 becomes smaller, thereby causing interlocking. Act to reduce the possibility of pixel shift. For example, as shown in FIG. 3A, when the display panel 10 is convexly curved, the spacing between the pair of first spacers 141 and the second spacers 142 disposed in the same sub-pixel intermediate region may become smaller (eg, The direction of the arrow in FIG. 3A), and the spacing between the pair of first spacers 141 and the second spacers 142 in other regions of the same sub-pixel is substantially constant or slightly changed. As shown in FIG. 3B, when the display panel 10 is concavely curved, the spacing between the pair of first spacers 141 and the second spacers 142 disposed at the end regions of the same sub-pixel will become smaller (as shown in FIG. 3B). The direction of the arrow is the same, and the spacing between the pair of first spacers 141 and the second spacers 142 in the middle region or other regions of the same sub-pixel is substantially constant or slightly changed. In one embodiment, when the display panel is bent 10, the signal line 116 (eg, the scan line) may be substantially parallel to the direction of extension of the central axis of curvature BC of the display panel 10. In another embodiment, when the display panel 10 is bent, the signal line 118 (eg, the data line) may be substantially parallel to the direction of extension of the central axis of curvature BC of the display panel 10.

Moreover, the proportion of the spacers of the spacers 140 on the display panel may vary according to the degree of bending desired by the panel, that is, different display regions may have different ratios of spacers. For the remaining related components and definitions, refer to the foregoing description. 4A and 4B are schematic views showing the bending of different display areas of the display panel according to an embodiment of the present invention. As shown in FIG. 4A and FIG. 4B, the display panel 10 includes the first The display area 101, the second display area 102, and the third display area 103 are located, and the third display area 103 is located between the first display area 101 and the second display area 102. The first display area 101, the second display area 102, and the third display area 103 respectively include at least three sub-pixels 100 shown in the above embodiments. The first spacers 141 and the second spacers 142 have a first spacer ratio in at least three sub-pixels 100 of the first display area 101; the first spacers 141 and the second spacers 142 At least three sub-pixels in the second display area 102 have a second gap ratio; the first spacers 141 and the second spacers 142 have a third gap in at least three sub-pixels of the third display area 103 Proportion of matter. For example, the sum of the contact areas of the first spacer 141 and the second spacer 142 in the first display area 101 with the first substrate 110 and the second substrate 120 respectively is the first ratio with respect to the unit area of the display panel. The proportion of the gap. The total area of contact between the first spacer 141 and the second spacer 142 in the second display region 102 and the first substrate 110 and the second substrate 120, respectively, is a second spacer ratio with respect to the unit area ratio of the display panel. The total contact area of the first spacer 141 and the second spacer 142 in the third display region 103 with the first substrate 110 and the second substrate 120 is a third spacer ratio with respect to the unit area ratio of the display panel. The first spacer ratio, the second spacer ratio, and the third spacer ratio are preferably less than or substantially equal to 0.6%, respectively, and greater than 0% (ie, 0% < first, second, or third spacer ratio <0.6 %), the ratio of the gap is no unit. Furthermore, the relevant description of the unit area, the first, second or third spacer ratio, the main spacer, the secondary spacer, and the like can be referred to the foregoing embodiment.

In this embodiment, the first display area 101 has a first curvature, the second display area 102 has a second curvature, and the first curvature is different from the second curvature. For example, the first display area 101 and the second display area 102 are respectively located at two ends of the display panel 10 and are bent to different degrees in different directions. For example, the first display area 101 is curved toward the direction C1 and the second display area 102 is facing Direction C2 is bent, And the direction C1 and the direction C2 are opposite directions such that the first display area 101 has a first radius of curvature R1 and the first display area 102 has a second radius of curvature R2 different from the first radius of curvature R1. In other embodiments, direction C1 and direction C2 are substantially the same direction. When the degree of curvature of the first display area 101 is greater than the degree of bending of the second display area 102 (ie, the first curvature is greater than the second curvature, or the first radius of curvature R1 is less than the second radius of curvature R2), wherein the first spacer The ratio is preferably greater than the second spacer ratio. That is, in the display area where the degree of curvature of the display panel 10 is greater, the ratio of the spacers may be relatively high, that is, in the display area, the first spacers 141 and the second spacers 142 are respectively associated with the first substrate 110 and The total contact area of the second substrate 120 is relatively high with respect to the unit area ratio of the display panel.

In this embodiment, the third display area 103 is located between the first display area 101 and the second display area 102 and is less affected by stress (ie, the degree of bending is so small that the substantially planar area can be ignored). In order to facilitate the fabrication and cost consideration of the spacer 140, the third spacer ratio in the third display area 103 may be based on the first spacer ratio of the first display area 101 and/or according to the second display area 102. The proportion of the gap.

For example, in an embodiment, the display panel 10 may have substantially the same spacer ratio in the first display area 101, the second display area 102, and the third display area 103, and the spacer ratio is maximized by curvature or It is determined by the display area having the smallest radius of curvature, for example, the first spacer ratio of the first display area 101. Therefore, it is only necessary to use a single mask to complete the fabrication of the spacers in the three display areas without particularly considering the configuration of the spacers in the display area having a small curvature.

In another embodiment, the display panel 10 may have a spacer ratio corresponding to its curvature requirement in the first display area 101 and the second display area 102. For example, for the curvature requirements of the first display area 101 and the second display area 102, two masks for making different gap ratios are provided, so that the first The display area 101 has a first spacer ratio and the second display area 102 has a second spacer ratio. Moreover, the third display area 103 is substantially a planar area, and thus the third display area 103 can use the photomask used by the first display area 101 or the second display area 102 to fabricate the spacer. That is, the third spacer ratio of the third display region 103 is based on the first spacer ratio or the second spacer ratio.

In another embodiment, the area of the third display area 103 adjacent to the first display area 101 and the second display area 102 is considered as a stress transition area, so the third display area 103 can be further divided into the first sub-display area 103a. And a second sub-display area 103b, wherein the first sub-display area 103a is adjacent to the first display area 101, and the second sub-display area 103b is adjacent to the second display area 102. Corresponding to the distinction between the first sub-display area 103a and the second sub-display area 103b, the ratio of the spacers in the first sub-display area 103a is the first sub-interstitial ratio, and the ratio of the inter-space in the second sub-display area 103b is the second. Sub-interstitial ratio. In this embodiment, the first sub-display area 103a preferably uses the photomask used in the first display area 101 to fabricate the spacers, so that the first sub-interstitial ratio is based on the first spacer ratio, and the second sub-display area. 103b preferably uses the reticle used in the second display area 102 to fabricate the spacer so that the second sub-interstitial ratio is based on the second spacer ratio.

In still another embodiment, the first display area 101 has a first curvature, the second display area 102 has a second curvature, and the first curvature is substantially the same as the second curvature, and the direction C1 and the direction C2 may be substantially the same direction. Or the opposite direction. Wherein the first spacer ratio is preferably substantially the same as the second spacer ratio. Furthermore, the third display area 103 is substantially a planar area, and the third spacer ratio and range of the third display area 103 can be referred to the foregoing embodiment, and it is no longer said.

Please refer to Table 1. Table 1 shows the experimental results of the minimum radius of curvature (R) of the different thickness (T) display panels of the spacer structure which are interlaced on the upper and lower substrates with respect to different spacers. It can be seen from Table 1 that when the thickness of the display panel is about 180 μm, the ratio of the spacers can be When the thickness is about 0.6%, 0.4%, and 0.2%, respectively, the minimum curvature radius R of the display panel bending can be about 10 mm, about 16 mm, and about 25 mm, respectively. When the thickness of the display panel is about 240 μm and the ratio of the spacers is about 0.6%, 0.4%, and 0.2%, respectively, the minimum curvature radius R of the display panel bending can be about 24 mm, about 30 mm, and about 55 mm, respectively. When the thickness of the display panel is about 310 μm and the ratio of the spacers is about 0.6%, 0.4%, and 0.2%, respectively, the minimum curvature radius R of the display panel bending can reach about 35 mm, about 52 mm, and about 70 mm, respectively.

Compared with the prior art (ie, the design described in the present embodiment), the display panel of the present invention has a staggered manner or a similar arrangement in the upper and lower substrates. The spacers only need to form the upper and lower substrates respectively according to the configuration, and there is no need to specifically consider the problem that the spacers are specifically aligned with each other, so that the process is relatively simple and the panel bending limit can be improved. Moreover, before the display panel of the present invention is bent, the positioning of the spacers does not have any adverse effect on the panel, and can also be applied to a general panel. In addition, when the display panel of the present invention is curved, the first spacer and the second spacer may be interlocked to prevent the pixel offset from effectively fixing the pixel.
