Description
Technical Field
The present invention relates to a display panel, and more particularly, to a display panel for limiting frame adhesives.
Background
Since a Display panel (TFT LCD) has excellent characteristics such as high image quality, good space utilization efficiency, low power consumption, and no radiation, it has gradually become the main stream of the market.
Generally, a display panel is composed of a thin film transistor array substrate, a liquid crystal layer and a color filter substrate, wherein the thin film transistor array substrate is attached to the color filter substrate by the adhesion of the frame glue located at the periphery, and the liquid crystal layer is sealed between the thin film transistor array substrate and the color filter substrate by the frame glue. Therefore, the sealant is mainly used for stably sealing the injected liquid crystal between the thin film transistor array substrate and the color filter substrate in the manufacturing process.
However, due to the limitation of the equipment, the frame sealant has a slight error in position relative to the periphery when coated to the periphery, so that the frame sealant may not be accurately coated to a proper position, and the frame sealant is too close to the display area (AA area) of the display panel or too far away from the display area (AA area) of the display panel.
When the sealant is too close to the display area (AA area) of the display panel, the sealant may contact the liquid crystal of the liquid crystal layer when the display panel is assembled, thereby causing contamination of the liquid crystal layer; on the contrary, when the sealant is too far away from the display area (AA area) of the display panel, the sealant may be cut on the display panel, so that the display panel may suffer from uneven brightness due to uneven pressure. In addition, when the sealant is coated, the sealant output amount is not uniform, and the luminance may also be non-uniform due to local gaps.
Therefore, how to develop a display panel that can effectively improve the above-mentioned defects and inconveniences is an important issue that related manufacturers are reluctant to find.
Disclosure of Invention
An objective of the present invention is to provide a display panel for limiting sealant coated on the periphery, so as to reduce the probability that the sealant is too close to or far away from the display area of the display panel, thereby meeting the design requirement of the assembly position.
Another objective of the present invention is to provide a display panel, which can effectively surround the periphery of the display panel with redundant sealant even if the sealant amount of the sealant coated on the periphery is not uniform, so as to avoid the uneven brightness.
One embodiment of the present invention discloses a display panel. The display panel has a display area and a peripheral area surrounding the display area. The display panel comprises an upper substrate, a lower substrate, a display medium, a sealing structure and a frame glue. The upper substrate and the lower substrate are arranged oppositely. The display medium is arranged between the upper substrate and the lower substrate and in the display area. The sealing structure is located in the peripheral region between the upper substrate and the lower substrate and surrounds the display medium, and the sealing structure comprises a surrounding body. The surrounding body is arranged between the upper substrate and the lower substrate, is positioned in the peripheral area and surrounds the display medium, wherein the inside of the surrounding body is provided with a glue containing space, and the outer side of the surrounding body, which is opposite to the display medium, is provided with a groove communicated with the glue containing space. The frame glue is positioned in the glue containing space, and the groove continuously surrounds the frame glue. The surrounding body comprises an upper supporting piece and a lower supporting piece, wherein the upper supporting piece is positioned on the upper substrate, the lower supporting piece is positioned on the lower substrate, the outer side of the upper supporting piece relative to the display medium and the outer side of the lower supporting piece relative to the display medium are not physically contacted with each other so as to form the groove, and when the glue output amount of the frame glue is excessive, the frame glue in the glue containing space can be extruded out of the groove.
In an embodiment of the present invention, the upper supporting member and the lower supporting member are combined with each other by the sealant to form a sealing structure for sealing the display medium in the display region between the upper substrate and the lower substrate.
In this embodiment, the upper support member includes a first bottom, a first inner wall and a first outer wall. The first bottom is located on the upper substrate and surrounds the display medium. The first inner wall is located at one side of the first bottom near the display area and surrounds the display medium. The first peripheral wall is located on a side of the first bottom portion away from the display medium and surrounds the first inner enclosing wall. A first concave part is defined among the first bottom, the first inner enclosing wall and the first outer enclosing wall.
In this embodiment, the lower support comprises a second bottom, a second inner wall and a second outer wall. The second bottom is located on the lower substrate and surrounds the display medium. The second inner wall is located at one side of the second bottom near the display area, surrounds the display medium, and is combined with the first inner wall. The second outer surrounding wall is located at one side of the second bottom part far away from the display area, surrounds the second inner surrounding wall, and has the groove with the first outer surrounding wall. A second concave part is defined among the second bottom, the second inner wall and the second outer wall, and the second concave part and the first concave part jointly form the glue containing space. In addition, the height of the second outer surrounding wall is equal to the height of the second inner surrounding wall, and the height of the first outer surrounding wall is smaller than the height of the first inner surrounding wall.
In a variation of the described embodiment, the second peripheral wall is disposed in alignment with the first peripheral wall. Therefore, a first distance is formed between the first inner surrounding wall and the first outer surrounding wall, a second distance is formed between the second inner surrounding wall and the second outer surrounding wall, and the first distance is the same as the second distance.
In another variation of the described embodiment, the second peripheral wall is offset from the first peripheral wall. Therefore, a first distance is formed between the first inner wall and the first outer wall, a second distance is formed between the second inner wall and the second outer wall, and the first distance is different from the second distance.
In various variations of the described embodiment, the upper substrate is a color filter substrate and the lower substrate is an active array substrate; or, the upper substrate comprises a black matrix layer, and the upper support member is formed by forming a photosensitive spacer on the black matrix layer; alternatively, the lower support is an insulating layer (PL) or an organic protective layer (PV).
Another embodiment of the present invention discloses a display panel. The display panel comprises an upper substrate, a lower substrate, an upper supporting piece, a lower supporting piece and frame glue. The upper support is located at the peripheral position of the upper substrate to surround the display medium and is provided with a first concave part. The lower support is located at the peripheral position of the lower substrate to surround the display medium, is arranged opposite to the upper support and is provided with a second concave part. When the upper substrate and the lower substrate are overlapped, the upper supporting piece and the lower supporting piece are combined with each other, the first concave part and the second concave part form a glue containing space together, the outer side of the upper supporting piece relative to the display medium and the outer side of the lower supporting piece relative to the display medium are not in physical contact with each other, so that a continuous groove is formed, the groove is communicated with the glue containing space, and when the glue discharging amount of the frame glue is excessive, the frame glue in the glue containing space can be extruded out from the groove. The frame glue is positioned in the glue containing space and the groove and used for fixing the upper supporting piece and the lower supporting piece.
In summary, the display panel of the invention has at least the following advantages:
1. by means of the sealing structure of the display panel, the frame glue is limited in the glue containing space by the upper supporting piece and the lower supporting piece, so that the support strength and the integral structural strength of the cured frame glue in the sealing structure can be enhanced, the adhesion strength of the frame glue with the upper supporting piece and the lower supporting piece can be improved, and the effect of taking the structural strength into consideration is achieved;
2. by the sealing structure of the display panel, the frame glue and the liquid crystal layer can be effectively separated and positioned in the peripheral area and the display area, and the probability that the frame glue is too close to or far away from the liquid crystal layer is reduced so as to meet the design requirement of the paired positions; and
3. by the sealing structure of the display panel, when the upper substrate and the lower substrate are assembled, the redundant frame glue coated in the glue containing space can overflow from the lateral groove of the surrounding body, so that the frame glue output amount can be tolerated to have a small error, and the processing capability and stability are improved.

Detailed Description
In order to make the present disclosure more complete and complete, reference is made to the accompanying drawings, in which like references indicate similar or analogous elements, and to the various embodiments of the invention described below. However, it will be understood by those of ordinary skill in the art that the examples provided below are not intended to limit the scope of the present invention. In addition, the drawings are only for illustrative purposes and are not drawn to scale.
Referring to fig. 1 to 2, fig. 1 is a top view of a display panel 100 according to the present invention, and fig. 2 is a schematic diagram of the display panel 100 according to an embodiment of the present invention.
The display panel 100 of the present invention can be seen from the plane direction (refer to the top view of fig. 1) to distinguish the display area S and the peripheral area E. In the top view, the display area S is located at a substantially central area of the plane of the display panel 100, and corresponds to a pixel array (not shown) in the display panel 100, which is an area for providing display content. The peripheral region E is located at the periphery of the plane of the display panel 100 and completely surrounds the display region S therein. In practical situations, the peripheral region E is a reserved area of the display panel 100 that is left in consideration of the trimming tolerance, and therefore, the width of the peripheral region E can be adjusted according to the actual situation by the designer.
Referring to fig. 2 to 4, fig. 3 is a cross-sectional view taken along line 3-3 in fig. 2, and fig. 4 is a side view of the display panel 100 viewed from direction D in fig. 2.
As shown in fig. 3, the display panel 100 of the present invention includes an upper substrate 200, a display medium 400, a sealing structure 500, and a lower substrate 300. The upper substrate 200 and the lower substrate 300 are disposed opposite to each other, and each has a display region S and a peripheral region E. The upper substrate 200 and the lower substrate 300 may be, for example, a color filter substrate and a thin film transistor array substrate, and respectively have a common electrode (not shown) and a pixel array electrode (not shown). The display medium 400 is disposed between the upper substrate 200 and the lower substrate 300 and only located in the display region S. Specifically, the display medium 400 is mainly used for displaying images, such as a liquid crystal layer, and liquid crystal molecules 410 in the liquid crystal layer incline at different angles according to a voltage difference between a pixel array electrode and a common electrode, so that the display panel 100 displays different gray scales in the display area S, and further displays images.
The sealing structure 500 is also between the upper substrate 200 and the lower substrate 300 and is located in the peripheral region E. The sealing structure 500 surrounds the display medium 400, and the display medium 400 is sealed between the sealing structure 500, the upper substrate 200 and the lower substrate 300.
Specifically, the sealing structure 500 includes an enclosure 510. The enclosure 510 is substantially a square ring, as shown in fig. 2, between the upper substrate 200 and the lower substrate 300 and in the peripheral region E. The enclosure 510 includes an inner sidewall 511 adjacent to the display region S and an outer sidewall 513 opposite to the display region S, the inner sidewall 511 of the enclosure 510 encloses and forms a central opening 520, an area of the central opening 520 substantially represents the display region S, and therefore, a space of the central opening 520 is used for accommodating the display medium 400. The enclosure 510 is hollow, and is sandwiched between the inner sidewall 511 and the outer sidewall 513, and the hollow interior thereof is a substantially square ring-shaped glue containing space 530, and the glue containing space 530 is filled with the sealant 600, so as to stabilize the overall structure of the enclosure 510. In addition, the outer sidewall 513 of the enclosure 510 has a groove 540, and the groove 540 is substantially square ring-shaped, connects the glue containing space 530 with the outside, and continuously surrounds the sealant 600 in the glue containing space 530.
In this embodiment, the enclosure 510 includes an upper support 550 and a lower support 560, which are formed on the upper substrate 200 and the lower substrate 300, respectively, and are composed of the upper support 550 and the lower support 560. The upper supporter 550 has a square ring shape and is disposed on the peripheral region E of the upper substrate 200. The lower supporter 560 has a square ring shape and is disposed on the peripheral region E of the lower substrate 300.
The cross section of the upper support 550 is substantially concave, and includes a first bottom 551, a first inner peripheral wall 552 and a first outer peripheral wall 553. The first base 551 is located on the surface of the upper substrate 200. The first inner wall 552 is located on one side of the first bottom 551 close to the central opening 520, i.e. the inner side of the upper support 550, and surrounds the central opening 520. The first peripheral wall 553 is located on the other side of the first bottom 551 away from the central opening 520, i.e., the outer circumferential side of the upper support 550, and surrounds the first inner peripheral wall 552. Accordingly, a first recess 554 may be defined between the first bottom 551, the first inner peripheral wall 552 and the first peripheral wall 553. The first bottom 551, the first inner peripheral wall 552 and the first peripheral wall 553 of the upper support 550 are not limited to being integrally formed or separately formed in this embodiment.
The cross-section of the lower support 560 is substantially concave, and includes a second bottom 561, a second inner peripheral wall 562 and a second outer peripheral wall 563. The second bottom 561 is positioned on the surface of the lower substrate 300. The second inner peripheral wall 562 is located on one side of the second bottom portion 561 near the central opening 520, i.e. the inner peripheral side of the lower support 560, and surrounds the central opening 520. The second outer perimeter wall 563 is located on the other side of the second bottom portion 561 away from the central opening 520, i.e. the outer perimeter side of the lower support 560, and surrounds the second inner perimeter wall 562. Therefore, a second recess 564 can be defined between the second bottom 561, the second inner peripheral wall 562 and the second outer peripheral wall 563. The second bottom portion 561, the second inner peripheral wall 562 and the second outer peripheral wall 563 are not limited to being integrally formed or being formed separately in this embodiment.
In this embodiment, the first peripheral wall 553 is disposed in alignment with the second peripheral wall 563 to form the outer wall 513 of the surrounding body 510, and further, the top surface of the first peripheral wall 553 is disposed in alignment with (or directly opposite to) the top surface of the second peripheral wall 563. First inner perimeter wall 552 is aligned with second inner perimeter wall 562 to form inner sidewall 511 of enclosure 510, and further, the top surface of first inner perimeter wall 552 is aligned with (or directly opposite) the top surface of second inner perimeter wall 562. In this embodiment, since first peripheral wall 553 is disposed in alignment with second peripheral wall 563 and first inner peripheral wall 552 is disposed in alignment with second inner peripheral wall 562, a first spacing G1 between first inner peripheral wall 552 and first peripheral wall 553 is equal to a second spacing G2 between second inner peripheral wall 562 and second outer peripheral wall 563, as shown in fig. 3.
In this embodiment, the height H1 of first peripheral wall 553 is less than the height H2 of first inner peripheral wall 552, in other words, the vertical height from the top surface of first peripheral wall 553 to first bottom 551 is less than the vertical height from the top surface of first inner peripheral wall 552 to first bottom 551. The height H3 of the second peripheral wall 563 is equal to the height H4 of the second inner peripheral wall 562, in other words, the vertical height from the top of the second peripheral wall 563 to the second bottom 561 is equal to the vertical height from the top of the second inner peripheral wall 562 to the second bottom 561.
In addition, the manufacturing method of the display panel 100 initially includes the following steps.
Step (1): providing an upper substrate 200 and a lower substrate 300;
step (2): forming an upper supporter 550 and a lower supporter 560 on the outer peripheral region E of the upper substrate 200 and the outer peripheral region E of the lower substrate 300, respectively;
and (3): coating the sealant 600 in the first recess 554 of the upper support 550 or the second recess 564 of the lower support 560;
and (4): filling the display medium 400 in the display region S of the upper substrate 200 or the display region S of the lower substrate 300;
and (5): assembling the upper substrate 200 and the lower substrate 300, wherein the first recess 554 and the second recess 564 together form a glue-accommodating space 530; and
and (6): the sealant 600 is cured.
Specifically, in the step (2), the upper support 550 and the lower support 560 of the surrounding body 510 may be formed on the upper substrate 200 and the lower substrate 300 respectively by, for example, exposure and development, and the like, and particularly, the first recess 554 of the upper support 550 and the second recess 564 of the lower support 560 may be formed by adjusting the exposure amount at different positions by using a similar technique such as a Halftone Mask (Halftone Mask).
Alternatively, the manufacturing method of the upper support 550 or the lower support 560 may be integrated into the manufacturing process of the upper substrate 200 or the lower substrate 300, so that the upper support 550 or the lower support 560 does not need to be additionally manufactured, thereby saving the manufacturing cost. In other words, the upper supporter 550 or the lower supporter 560 may be formed at the periphery of an originally existing layer in the display panel 100. For example, the upper support 550 and the Photosensitive Spacer (PS) are formed by the same mask process, such as forming a black matrix layer (BM) included in the upper substrate 200, so that the upper support 550 can be formed by the photosensitive spacer and the black matrix layer; the upper support 550 is formed by being integrated into the photosensitive spacer process or the black matrix layer process. The lower support 560 is integrated with the process of forming an insulating layer (PL) or an organic protective layer (PV), such as a silicon nitride layer, of the lower substrate 300.
In step (3), the sealant 600 is filled or coated in the first recess 554 or the second recess 564.
In step (5), the upper substrate 200 and the lower substrate 300 are stacked such that the upper support 550 is aligned with the lower support 560 and integrated with each other by the sealant 600, such that the display medium 400 is sealed in the display region S (the central opening 520). By combining the upper support 550 and the lower support 560, the first recess 554 and the second recess 564 are connected together to form the sealant accommodating space 530 for accommodating the sealant 600, and the first inner wall 552 of the upper support 550 and the second inner wall 562 of the lower support 560 are in physical contact with each other to enclose the display medium 400 in the central opening 520; in addition, the first peripheral wall 553 of the upper support 550 and the second peripheral wall 563 of the lower support 560 are not physically contacted with each other, so that the continuous groove 540 is formed on the outer sides of the upper support 550 and the lower support 560.
Thus, since the first inner surrounding wall 552 of the upper supporting member 550 and the second inner surrounding wall 562 of the lower supporting member 560 are physically contacted with each other, the sealant 600 is confined in the sealant containing space 530, so that the sealant 600 does not approach the display region S too much, thereby preventing the sealant 600 from contacting the liquid crystal molecules 410 in the liquid crystal layer and further contaminating the liquid crystal molecules 410 in the liquid crystal layer, or the sealant 600 does not get far away from the display region S too much, thereby causing the phenomenon of uneven brightness due to local gaps.
In addition, when the sealant 600 is discharged too much, the sealant 600 in the sealant containing space 530 can be extruded from the groove 540, and the sealant 600 extruded from the groove 540 can be removed by mechanical scraping, so that the sealant 600 fills the groove 540, and the phenomenon of uneven brightness caused by local gaps is avoided.
In step (6), the sealant 600 is, for example, a thermosetting or photo-curing resin, and can be cured by heating or UV light irradiation.
Referring to fig. 5 to 6, fig. 5 is a top view of a display panel 101 according to another embodiment of the present invention, and fig. 6 is a cross-sectional view taken along line 6-6 in fig. 5.
The display panel 101 in this embodiment is substantially the same as the display panel 100 described in fig. 2 to 4, and the differences are as follows.
In this embodiment, the first spacing G3 between the first inner peripheral wall 552 and the first outer peripheral wall 553 is smaller than the second spacing G4 between the second inner peripheral wall 562 and the second outer peripheral wall 563, so that when the first inner peripheral wall 552 is disposed in alignment with the second inner peripheral wall 562, the first outer peripheral wall 553 and the second outer peripheral wall 563 are disposed alternately, i.e., the first outer peripheral wall 553 is disposed in non-alignment with the second outer peripheral wall 563.
In this alternative embodiment, height H5 of first peripheral wall 553 is less than height H6 of first inner peripheral wall 552, in other words, the vertical height from the top surface of first peripheral wall 553 to first bottom 551 is less than the vertical height from the top surface of first inner peripheral wall 552 to first bottom 551. The height H7 of the second peripheral wall 563 is equal to the height H8 of the second inner peripheral wall 562, in other words, the vertical height from the top of the second peripheral wall 563 to the second bottom 561 is equal to the vertical height from the top of the second inner peripheral wall 562 to the second bottom 561. Thus, the groove 540 formed between the upper supporter 550 and the lower supporter 560 of the display panel 101 facilitates the extrusion of the excess sealant 600, and the larger second distance G4 between the second inner wall 562 and the second outer wall 563 also increases the contact area between the sealant 600 and the lower supporter 560, thereby improving the adhesion strength.
However, in another embodiment of the present invention, the height H5 of the first peripheral wall 553 is not limited to be less than the height H6 of the first inner peripheral wall 552, but may be equal to the height H6, or the height H563 of the second outer peripheral wall is not limited to be equal to the height H of the second inner peripheral wall 562, or is higher than the height H of the second inner peripheral wall 562, which not only increases the contact area between the sealant and the lower support, increases the adhesion strength, but also reduces the amount of the sealant extruded out of the groove.
In summary, with the sealing structure of the display panel of the present invention, the frame adhesive is confined in the adhesive containing space by the upper supporting member and the lower supporting member, so that the cured frame adhesive in the sealing structure can enhance the supporting strength and the overall structural strength, and thereby the adhesive strength between the frame adhesive and the upper supporting member and the lower supporting member can be improved, and the effect of taking account of the structural strength can be achieved. In addition, the sealing structure of the display panel can effectively separate and position the frame glue and the liquid crystal layer in the peripheral area and the display area, and reduce the chance that the frame glue is too close to or far away from the liquid crystal layer. Moreover, when the upper substrate and the lower substrate of the display panel are assembled, the excess sealant coated in the sealant containing space can overflow from the groove of the surrounding body, which can allow some error of sealant output amount, thereby improving the processing capability and stability.
Hereinbefore, specific embodiments of the present invention are described with reference to the drawings. However, those skilled in the art will appreciate that various modifications and substitutions can be made to the specific embodiments of the present invention without departing from the spirit and scope of the invention. Such modifications and substitutions are intended to be included within the scope of the present invention as defined by the appended claims.
