technical field

The present invention relates to a display technology of a display panel, in particular to a structure of a display panel.

Background technique

Generally speaking, the display panel is mainly composed of the array substrate and the opposite substrate, the liquid crystal layer is sealed inside, and then assembled with the backlight module to form a liquid crystal display panel. Here, basically, the array substrate is roughly aligned with the opposite substrate.

During the process of transporting or assembling the display panel, or when the display panel is a curved display device (that is, a flat display panel is bent into a curved display panel), when the display panel is affected by an external force, the array substrate and the opposite substrate There is a relative displacement (misalignment) between them. In this way, the spacers located on the array substrate or the opposite substrate are likely to scrape off the alignment layer or protective layer on the array substrate or the opposite substrate on the opposite side, and, during the relative displacement of the array substrate and the opposite substrate During the process, the spacers easily push the scraped alignment layers or protection layers into the sub-pixel regions, thereby affecting the display quality of the effective display region.

FIG. 4 is a schematic top view schematic diagram of the structure of the displaced display panel according to an embodiment of the present invention. FIG. 5A is a schematic cross-sectional view of the display panel corresponding to the line A2 ′-A2 ′ in FIG. 4 . FIG. 5B is a schematic cross-sectional view of the display panel corresponding to the line B2 ′-B2 ′ in FIG. 4 .

When the display panel 100 is bent, squeezed or moved to cause the first substrate 110 and/or the second substrate 120 to be stressed, the amount of extension between the first substrate 110 and the second substrate 120 is different, resulting in displacement or It is a dislocation situation, and it can be called a dislocation state between the first substrate 110 and the second substrate 120 relative to the normal alignment state. Please refer to FIG. 4, FIG. 5A and FIG. 5B, when the first substrate 110 and the second substrate 120 are displaced, for example, the relative displacement between the first substrate 110 and the second substrate 120 can be substantially along the second direction D2. , then the first spacer 172 and the second spacer 174 can be displaced substantially along the second direction D2 to approach the protruding block 164 or move away from the protruding block 164 . Here, taking the first spacer 172 as an example, when the first spacer 172 substantially moves along the second direction D2 close to the bump 164 and the relative displacement is between the first inner distance D11 and the first inner distance D11 and the bump When the sum of the width U2 of 164 is between, in the vertical projection direction D3, the vertical projection range of the first spacer 172 and the vertical projection range of the protrusion 164 at least partially overlap, and the first spacer 172 contacts the corresponding part of the light shielding component 160 At the bump 164 (for example: the first spacer 172 contacts the top surface 164s of the bump 164 or the first spacer 172 contacts the protective layer or alignment layer PI on the top surface 164s of the bump 164, etc.); and the second spacer The vertical projection range of 174 does not overlap with the vertical projection range of the protrusion 164 , and the second spacer 174 does not touch the corresponding protrusion 164 of the light shielding component 160 . For example, the first spacer 172 is displaced and may contact part or all of the top surface 164s of the bump 164 (or contact the protection layer or alignment layer PI located on the top surface 164s of the bump 164); the second spacer 174 displacement, and the vertical projection of the top surface 174s of the second spacer 174 is located within the projection range of the light shielding layer 162 (when the relative displacement is less than the second outer distance D22) or the vertical projection of the top surface 174s of the second spacer 174 At least partially beyond the projection range of the light shielding layer 162 (when the relative displacement is greater than the second outer distance D22). Viewed from another aspect, the second spacer 174 can see the relative displacement and not exceed the fourth edge 1623 of the light shielding layer 162 or cross the fourth edge 1623 of the light shielding layer 162 and enter the display range of the sub-pixel 150 (ie not covered by the light-shielding layer 162).

Here, when the displacement of the first spacer 172 is less than or substantially equal to the sum of the width U2 of the protrusion 164 and the first inner distance D11, the first spacer 172 may abut against the protrusion 164, in other words the first The distance between the substrate 110 and the second substrate 120 will increase, causing the top surface 174s of the second spacer 174 to be spaced apart from the surface 162s of the light-shielding layer 162, so that the top surface 174s of the second spacer 174 is spaced from the surface of the light-shielding layer 162. 162s has a gap G in the vertical projection direction. In different implementations, since the alignment layer PI conformally covers the outer surfaces of the light shielding element 160 and the spacer 170 , the gap G can substantially ignore the influence of the thickness of the alignment layer PI. From another perspective, the gap G may refer to the distance between the top surface 174s of the second spacer 174 and the surface 162s of the light shielding layer 162, or may refer to the distance between the top surface 174s of the second spacer 174. The distance between the alignment layer PI and the alignment layer PI located on the surface 162 s of the light shielding layer 162 .

When the first spacer 172 continues to move over the bump 164 and the second spacer 174 moves into the display range (not shown) of the sub-pixel 150, because the second spacer 174 and the light shielding layer 162 are in the vertical projection direction There is a gap G on D3, and the second spacer 174 scraped off the pollutants from the surface layer of the light-shielding layer 162 during the previous displacement process (such as the light-shielding layer 162, or the alignment layer PI on the surface 162s of the light-shielding layer 162 or the protection layer, etc.) will remain within the range of the light-shielding layer 162 (that is, not beyond the fourth edge 1623), so that these pollutants can be avoided from being pushed into the display range of the sub-pixel 150, thereby avoiding affecting the display quality of the display panel 100 .

Next, please refer to FIG. 1, FIG. 3A, and FIG. 3B again. In one embodiment, when the external force disappears, the first substrate 110 and the second substrate 120 return to their original positions, which can be referred to as the first substrate 110 and the second substrate. When the substrate 120 is in a normal alignment state, the projection of the top surface 172 s of the first spacer 172 is located between the first edge 132 and the bump 164 and does not overlap with the bump 164 . Likewise, the projection of the top surface 174 s of the second spacer 174 is located between the second edge 134 and the bump 164 and does not overlap with the bump 164 .

In some embodiments, in order to be able to contact at least the first spacer 172 , the bump 164 may have various designs. In an embodiment, the protruding bump 164 can be designed as a convex strip, and the extending direction of the protruding bump 164 is substantially the same as the extending direction of the light shielding layer 162 . In one embodiment, the centerline L1 of the bump 164 is substantially parallel to and coincides with the centerline L2 of the light shielding layer 162 , as shown in FIG. 2 . In another embodiment, in the vertical projection direction of the first substrate 110, the centerline of the bump 164 does not coincide with the centerline of the light-shielding layer 162 (not shown in the figure), and the bump 164 is far away from both sides of the light-shielding layer 162 For example, the range of the bump 164 does not touch the edges 1621 , 1623 of the light shielding layer 162 adjacent to the sides of the bump 164 . In one embodiment, as shown in FIG. 2 , in the vertical projection direction of the first substrate 110, the area A2 of the bump 164 (for example: the vertical projection range of the bump 164) occupies the area A1 of the light shielding layer 162 (for example: The proportion of the light-shielding layer 162 (vertical projection range) is about 5-40%.

In addition, the shape of the protrusion 164 may have various designs. In an embodiment, the bump 164 may be a cuboid, as shown in FIG. 6A . In addition, in order to facilitate the displacement of the first spacer 172 along the side of the protrusion 164 to the top surface 164s of the protrusion 164, so that the first spacer 172 is abutted against the protrusion 164 (for example: the first spacer 172 touches the protrusion block 164). In an embodiment, the bumps 164 can be designed to taper from the bottom to the top surface 164s, for example, a long trapezoid (as shown in FIG. 3A and FIG. 3B ), wherein the bumps 164 are respectively adjacent to the first The two side surfaces of the first spacer 172 and the second spacer 174 can be inclined planes or curved surfaces. In addition, in yet another embodiment, the top surface 164s of the bump 164 can be a plane (as shown in FIG. 6A ), or the two sides and the top surface of the bump 164 can be continuous arc surfaces (as shown in FIG. 6B ). Show).

In addition, in one embodiment, the bump 164 and the light-shielding layer 162 can be integrally formed. Here, the materials of the light-shielding layer 162 and the bump 164 can be the same type and manufactured in the same process. In addition, for technical considerations, the bumps 164 and the light-shielding layer 162 may also be produced in different process steps, for example, a photoresist material or a metal material is firstly formed on the inner surface 112 of the first substrate 110 as a pad A tall object 166, and then a layer of black photoresist material is covered on the raised object 166, as shown in FIG. , photoresist materials of various colors, and/or metal materials, etc.

In one embodiment, both the first spacer 172 and the second spacer 174 serve as a main photospacer, and the thickness S1 of the first spacer 172 and the thickness S2 of the second spacer 174 are substantially the same. When the first substrate 110 and the second substrate 120 are not displaced (for example: normal alignment state), the top surface 172s of the first spacer 172 contacts the corresponding light shielding layer 162 of the light shielding component 160, and the second spacer The top surface 174s of 174 is in contact with the corresponding light-shielding layer 162 of the light-shielding component 160 . For example, the top surface 172s of the first spacer 172 and the top surface 174s of the second spacer 174 contact the surface 162s of the light shielding layer 162, or the top surface 172s of the first spacer 172 and the top surface of the second spacer 174 The protection layer or the alignment layer PI on the surface 174 s is in contact with the protection layer or the alignment layer PI on the surface 162 s of the light shielding layer 162 . In different implementations, since the alignment layer PI conformally covers the outer surfaces of the light-shielding element and the spacer, the relationship between the thickness S1 and the thickness S2 can generally ignore the influence of the thickness of the alignment layer PI.

In another embodiment, the structure of the display panel 200 is substantially similar to that of the display panel 100, and reference may be made to the relevant descriptions of the foregoing embodiments, which are not described here, wherein the first spacer 172 serves as an auxiliary spacer (sub photospacer) , and the second spacer 174 serves as the main spacer.

Referring to FIG. 7 , FIG. 8A and FIG. 8B , the thickness S1 of the first spacer 172 is different from the thickness S2 of the second spacer 174 , and the thickness S1 of the first spacer 172 is smaller than the thickness S2 of the second spacer 174 . In the case where the first substrate 110 and the second substrate 120 are not displaced (for example: in a normal alignment state), the top surface 172s of the first spacer 172 is not in contact with the corresponding light-shielding layer 162 of the light-shielding component 160 and the first spacer The top surface 174s of 172 is between the top surface 164s of the bump 164 and the surface 162s of the light-shielding layer 162, and the top surface 174s of the second spacer 174 contacts the corresponding light-shielding layer 162 of the light-shielding component 160 (for example: the second spacer The top surface 174s of 174 is in contact with the surface 162s of the light-shielding layer 162 or the alignment layer PI or protective layer in contact with the surface 162s of the light-shielding layer 162). In this embodiment, the thickness T1 of the bump 164 is greater than the difference between the thickness S1 of the first spacer 172 and the thickness S2 of the second spacer 174 , and in another embodiment, the thickness of the bump 164 The thickness T1 is, for example, about 0.3 μm, but not limited thereto.

In this embodiment, please refer to FIG. 7, FIG. 8A and FIG. 8B, when the first substrate 110 and the second substrate 120 are not bent, squeezed or moved by external force, etc. When there is no displacement or misalignment, on the vertical projection direction D3 of the first substrate 110, the projection of the first spacer 172 (for example: auxiliary spacer) and the projection of the second spacer 174 (for example: main spacer) They are all located within the projected range of the light-shielding layer 162 , and respectively located on different sides of the bump 164 substantially parallel to the central line of the first electrode line 130 . In an embodiment, the projection of the top surface 172 s of the first spacer 172 (eg, auxiliary spacer) is located between the first edge 132 and the bump 164 and does not overlap with the bump 164 . Likewise, the projection of the top surface 174 s of the second spacer 174 (eg, the main spacer) is located between the second edge 134 and the protrusion 164 and does not overlap with the protrusion 164 . The first outer distance D12 is greater than the first inner distance D11, and the second outer distance D22 is greater than the second inner distance D21. Moreover, the first inner distance D11 is smaller than the second outer distance D22, and the first outer distance D12 is greater than the second inner distance D21.

FIG. 9 is a schematic top view schematic diagram of the structure of the displaced display panel according to another embodiment of the present invention. FIG. 10A is a schematic cross-sectional view of the display panel corresponding to the line C2-C2' in FIG. 9 . FIG. 10B is a schematic cross-sectional view of the display panel corresponding to the line D2-D2' in FIG. 9 .

When the display panel 200 is bent, squeezed or moved, etc., the first substrate 110 and the second substrate 120 are subjected to different forces, so that the extension amount between the first substrate 110 and the second substrate 120 is different, resulting in displacement or misalignment. situation. 9, FIG. 10A and FIG. 10B, when the first substrate 110 and the second substrate 120 are displaced, for example, the first substrate 110 and the second substrate 120 are displaced along the second direction D2, then the first The spacer 172 and the second spacer 174 are displaced along the second direction D2 toward the protruding block 164 or away from the protruding block 164 . Here, taking the first spacer 172 (for example: auxiliary spacer) as an example, when the first spacer 172 moves along the second direction D2 close to the bump 164 and the relative displacement is between the first inner distance D11 and the first inner distance Between the sum of the distance D11 and the width U2 of the bump 164, on the vertical projection direction D3 of the first substrate 110, the first spacer 172 at least partially overlaps with the bump 164 and contacts the corresponding bump 164 of the light shielding component 160 (For example: the first spacer 172 contacts the surface 162s of the bump 164 or contacts the protection layer or the alignment layer PI located on the top surface 164s of the bump 164), and the second spacer 174 (for example: main spacer) and the bump 164 do not overlap and do not contact the corresponding bump 164 of the light shielding component 160 (for example: the second spacer 174 does not contact the surface 162s of the bump 164 or does not contact the protective layer or alignment layer PI located on the top surface 164s of the bump 164) . For example, the first spacers 172 are displaced and may contact some or all of the top surfaces 164s of the bumps 164 (or contact the protective layer or alignment layer PI on some or all of the top surfaces 164s of the bumps 164 ). and, the second spacer 174 is displaced, and the vertical projection range of the top surface 174s of the second spacer 174 is located within the vertical projection range of the light shielding layer 162 (for example: when the relative displacement is less than the second outer distance D22) or the first The vertical projection range of the top surface 174s of the two spacers 174 at least partially exceeds the vertical projection range of the light shielding layer 162 (for example: when the relative displacement is greater than the second outer distance D22 ) and enters the range of the sub-pixel 150 . Viewed from another perspective, the second spacer 174 can see the amount of relative displacement and does not exceed the fourth edge 1623 of the light shielding layer 162 or cross the fourth edge 1623 of the light shielding layer 162 and enter the display range of the sub-pixel 150 (eg : not covered by the light-shielding layer 162).

Here, when the displacement of the first spacer 172 is less than or substantially equal to the sum of the width U2 of the protrusion 164 and the first inner distance D11, the first spacer 172 may abut against the protrusion 164, in other words the first The distance between the substrate 110 and the second substrate 120 will increase, causing the top surface 174s of the second spacer 174 to be spaced apart from the surface 162s of the light-shielding layer 162, so that the top surface 174s of the second spacer 174 is spaced from the surface of the light-shielding layer 162. 162s has a gap G in the vertical projection direction D3.

When the first spacer 172 continues to move over the bump 164 and the second spacer 174 moves into the display range (not shown) of the sub-pixel 150, because the second spacer 174 and the light shielding layer 162 are in the vertical projection direction There is a gap G on the D3, and the second spacer 174 is scraped from the surface layer of the light-shielding layer 162 during the previous displacement process (for example, the light-shielding layer 162, the alignment layer PI or the protective layer on the surface 162s of the light-shielding layer 162 pollutants) will stay within the range of the light-shielding layer 162 (for example: not exceeding the fourth edge 1623), so that these pollutants can be avoided from being pushed into the display range of the sub-pixel 150, thereby avoiding affecting the display of the display panel 200 quality.

Next, please refer to FIG. 7, FIG. 8A, and FIG. 8B again. When the external force disappears, the first substrate 110 and the second substrate 120 return to their original positions, that is, the first substrate 110 and the second substrate 120 are in a normal alignment state. , the projection of the top surface 172s of the first spacer 172 (for example: auxiliary spacer) is located between the first edge 132 and the bump 164 and does not overlap with the bump 164 . Likewise, the projection of the top surface 174 s of the second spacer 174 (eg, the main spacer) is located between the second edge 134 and the protrusion 164 and does not overlap with the protrusion 164 .

FIG. 11 is a schematic structural diagram of a spacer according to an embodiment of the present invention. For the sake of clarity, FIG. 11 only shows the structural schematic diagrams of the spacers 172 and 174 , the second substrate 120 , and the alignment layer PI. The spacer shown in FIG. 11 (for example: the first spacer 172 and/or the second spacer 174) configuration is substantially the same as the spacer shown in FIG. 3A, the difference is that the spacer shown in FIG. 11 consists of A plurality of film layers are stacked on each other and the alignment layer PI is covered on the outside of these stacked film layers. For example, color filter layers of different colors can be stacked on each other or a plurality of photoresist layers can be formed. stacked on top of each other. In addition, the first spacer 172 and the second spacer 174 can be cylindrical, conical, pyramidal, etc., and can be adjusted according to actual needs.

To sum up, in the display panel of the embodiment of the present invention, bumps are provided on the light-shielding layer of the first substrate, and the first spacer and the second spacer on the second substrate are along the extension of the first electrode line. The directions are arranged in a staggered manner, and the first spacer and the second spacer are respectively arranged correspondingly to the corresponding bumps. When the first substrate and the second substrate are displaced, the first spacer can touch the bump during the displacement process, so that there is a gap between the second spacer and the light shielding layer. Thereby, the second spacer is less likely to scratch the alignment layer or the protective layer during the displacement process, or the pollutants caused by scratching the alignment layer or the protective layer during the displacement process of the second spacer are less likely to enter the range of the sub-pixels , so as to avoid affecting the display quality of the display panel.
