Usually, a circle of frame sealing adhesive is required to be arranged between the thin film transistor array substrate and the color film substrate, so that the thin film transistor array substrate and the color film substrate are adhered together. When the display panel is subjected to a box forming process, uncured frame sealing glue is coated on the color film substrate, and after the thin film transistor array substrate and the color film substrate are assembled, the uncured frame sealing glue is heated and pressurized to be cured. In order to maintain the uniformity of the periphery of the display panel, spacers, such as support balls, are added to the sealant. Since the non-display area of the display panel has different numbers of layers of electrodes at different positions and the sizes of the support balls are substantially the same, the thickness of the display panel in the non-display area is different, for example, the number of electrode layers in the binding area of the non-display area is larger, the number of electrode layers in other areas of the non-display area is smaller, the display panel is thicker in the area with the larger number of electrode layers, and the area with the smaller number of electrode layers is thinner, which causes the display panel to have display color difference at the periphery of the display area and display non-uniformity (edge mura).

Detailed Description
To further illustrate the technical means and effects of the present invention adopted to achieve the predetermined objects, the following detailed description of the embodiments, structures, features and effects of the display panel, the manufacturing method and the display device according to the present invention with reference to the accompanying drawings and the preferred embodiments is as follows:
[ example one ]
Fig. 1 is a schematic plan view illustrating a display panel according to a first embodiment of the present invention, fig. 2 is a schematic perspective view illustrating the display panel without sealant according to the first embodiment of the present invention, fig. 3 is a schematic cross-sectional view illustrating the display panel according to the first embodiment of the present invention, and fig. 4 is a schematic perspective view illustrating the display panel with sealant according to the first embodiment of the present invention.
As shown in fig. 1 to 4, a display panel according to a first embodiment of the present invention includes a first substrate 10, a second substrate 20 disposed opposite to the first substrate 10, and a liquid crystal layer 30 disposed between the first substrate 10 and the second substrate 20. Preferably, positive liquid crystal molecules, that is, liquid crystal molecules having positive dielectric anisotropy are used in the liquid crystal layer 30. As shown in fig. 3, in the initial state, the positive liquid crystal molecules in the liquid crystal layer 30 are aligned parallel to the first substrate 10 and the second substrate 20, and the alignment direction of the positive liquid crystal molecules near the first substrate 10 is parallel or antiparallel to the alignment direction of the positive liquid crystal molecules near the second substrate 20.
The display panel has a display area AB and a non-display area AA located at the periphery of the display area AB. The first substrate 10 and the second substrate 20 have a first spacing region and a second spacing region between them and within the non-display area AA, and a first height h1 of the first spacing region is greater than a second height h2 of the second spacing region. The frame sealing adhesive 40 is disposed between the first substrate 10 and the second substrate 20 and in the non-display area AA, and the first substrate 10 and the second substrate 20 are bonded together by the frame sealing adhesive 40. The frame sealing glue 40 is internally provided with a first supporting structure 41 and a second supporting structure 42, the height of the first supporting structure 41 is greater than that of the second supporting structure 42, the first supporting structure 41 is located in the first spacing region and has the same height as the first height h1 of the first spacing region, and the second supporting structure 42 is located in the second spacing region and has the same height as the second height h2 of the second spacing region.
According to the invention, the first supporting structure 41 and the second supporting structure 42 with different heights are arranged in the frame sealing glue 40, the first supporting structure 41 corresponds to the first spacing area, the second supporting structure 42 corresponds to the second spacing area, and the first supporting structure 41 and the second supporting structure 42 support the display panel together, so that the thickness of the display panel in the non-display area AA is uniform, and the phenomena of uneven display and color difference at the periphery of the display area AB are avoided.
Further, as shown in fig. 4, the frame sealing adhesive 40 is provided with the support balls 43(SP), the height of the support balls 43 is the same as the second height h2 of the second pitch region, and the support balls 43 in the second pitch region are used as the second support structures 42, i.e. in this embodiment, the second support structures 42 are the support balls 43. The support balls 43 are mixed in the frame sealing adhesive 40, and when the frame sealing adhesive 40 is coated, the support balls 43 are also coated on the substrate. The first supporting structure 41 is a supporting Pillar (PS), wherein the supporting pillar is fabricated on the substrate as the first supporting structure 41 before the substrate is not coated with the frame sealing adhesive 40. In this embodiment, one end of the first supporting structure 41 is connected to the first substrate 10, and the other end of the first supporting structure 41 is abutted against the second substrate 20, that is, a supporting pillar is fabricated on the first substrate 10 as the first supporting structure 41. Of course, in other embodiments, one end of the first supporting structure 41 is connected to the second substrate 20, and the other end of the first supporting structure 41 is abutted against the first substrate 10, that is, a supporting pillar is fabricated on the second substrate 20 as the first supporting structure 41.
Further, a third supporting structure 13 is disposed between the first substrate 10 and the second substrate 20 and in the display area AB, the third supporting structure 13 is also a supporting column (PS), the third supporting structure 13 supports the first substrate 10 and the second substrate 20 in the liquid crystal layer 30, and the third supporting structure 13 is matched with the first supporting structure 41 and the second supporting structure 42 in height, so that the cell thickness of the display panel in the display area AB is the same as the cell thickness of the non-display area AA. Here, the first support structure 41 may be formed together with the third support structure 13, but since the first substrate 10 or the second substrate 20 has different protrusion heights in the display area AB and the non-display area AA, the first support structure 41 and the third support structure 13 may have different heights.
In practical application, when the first substrate 10 and the second substrate 20 are pressed together, the supporting column has a certain compression amount, in order to make the thickness of the display panel more uniform, the compression amount can be taken into consideration, and the following table shows the compression amount of the supporting column and the simulation data of the number, size and height of the supporting column:
the table I is a simulation relation between the compression amount of the support columns and the size (diameter) of the support columns, the table II is a simulation relation between the compression amount of the support columns and the number of the support columns, and the table III is a simulation relation between the compression amount of the support columns and the height of the support columns. It can be seen from the above three tables that the number, size and height of the support columns all affect the compression amount of the support columns, so that not only the height of the support columns but also the number and size of the support columns need to be considered when the support columns are actually arranged. For example, three support columns are provided per square millimeter in the first pitch region, the support columns have a diameter of 5 μm and a height of 3 μm, and the compression amount of the corresponding support columns is 0.70 μm, so that the actual height of the support columns is only 2.3 μm after the first substrate 10 and the second substrate 20 are bonded together.
Further, the second substrate 20 is provided with metal layers in the non-display area AA, and the number of the metal layers in the first interval area is smaller than that in the second interval area. The metal layer can be a contact pin of the binding region, so that an external signal is in signal connection with the data line, the scanning line and the touch line. Of course, the metal layer is not required to be disposed in the second spacing region, and the metal layer is only disposed in the first spacing region. That is, since the first and second pitch regions have different functions, the number of metal layers in the regions thereof is also different, resulting in different protrusion heights of the second substrate 20 in the first and second pitch regions.
In this embodiment, as shown in fig. 3, the first substrate 10 is a color film substrate, the color resist layers 12 arranged in an array and the black matrix 11 separating the color resist layers 12 are disposed on the first substrate 10, and the color resist layers 12 include color resist materials of three colors of red (R), green (G), and blue (B), and form sub-pixels of three colors of red (R), green (G), and blue (B) correspondingly. The black matrix 11 corresponds to the scanning lines, the data lines, and the non-transparent electrodes such as the thin film transistors in the display area AB, and the black matrix 11 also corresponds to the entire non-display area AA.
The second substrate 20 is an array substrate, the second substrate 20 defines a plurality of pixel units on a side facing the liquid crystal layer 30 by a plurality of scan lines and a plurality of data lines which are insulated from each other and crossed, a pixel electrode 22 and a thin film transistor are arranged in each pixel unit, and the pixel electrode 22 is electrically connected with the data lines of the adjacent thin film transistors through the thin film transistors. The thin film transistor includes a gate electrode, an active layer, a drain electrode and a source electrode, the gate electrode and the scan line are located in the same layer and electrically connected, the gate electrode and the active layer are isolated by an insulating layer, the source electrode and the data line are electrically connected, and the drain electrode and the pixel electrode 22 are electrically connected through a contact hole.
As shown in fig. 3, in the present embodiment, a common electrode 21 is further disposed on a side of the second substrate 20 facing the liquid crystal layer 30, and the common electrode 21 and the pixel electrode 22 are located at different layers and insulated and isolated by an insulating layer. The common electrode 21 may be located above or below the pixel electrode 22 (the common electrode 21 is shown below the pixel electrode 22 in fig. 1). Preferably, the common electrode 21 is a planar electrode disposed over the entire surface, and the pixel electrode 22 is a block electrode disposed in one block in each pixel unit or a slit electrode having a plurality of electrode bars to form a Fringe Field Switching (FFS) mode. Of course, In other embodiments, the pixel electrode 22 and the common electrode 21 may be located on the same layer, but they are insulated and isolated from each other, and each of the pixel electrode 22 and the common electrode 21 may include a plurality of electrode stripes, and the electrode stripes of the pixel electrode 22 and the electrode stripes of the common electrode 21 are alternately arranged to form an In-Plane Switching (IPS) mode; alternatively, in other embodiments, the second substrate 20 is provided with the pixel electrode 22 at a side facing the liquid crystal layer 30, and the first substrate 10 is provided with the common electrode 21 at a side facing the liquid crystal layer 30 to form a PET display architecture, a TN display architecture or a VA display architecture, and for other descriptions of the PET display architecture, the TN display architecture and the VA display architecture, reference is made to the prior art, and details are not repeated here.
Further, an upper polarizer 51 is disposed on the first substrate 10, a lower polarizer 52 is disposed on the second substrate 20, and a transmission axis of the upper polarizer 51 is perpendicular to a transmission axis of the lower polarizer 52.
The first substrate 10 and the second substrate 20 may be made of glass, acrylic, polycarbonate, or the like. The material of the common electrode 21 and the pixel electrode 22 may be Indium Tin Oxide (ITO), Indium Zinc Oxide (IZO), or the like.
The embodiment also provides a manufacturing method of a display panel, which is used for manufacturing the display panel, and the manufacturing method includes:
providing a first substrate 10, a second substrate 20 and a frame sealing adhesive 40, wherein the frame sealing adhesive 40 has a first supporting structure 41 and a second supporting structure 42. The first substrate 10 is a color film substrate, the second substrate 20 is an array substrate, and the specific structures of the color film substrate and the array substrate can refer to the prior art.
The frame sealing adhesive 40 is coated on the first substrate 10 and/or the second substrate 20 and corresponds to the non-display area AA, that is, the frame sealing adhesive 40 may be coated on the first substrate 10, the second substrate 20, or both the first substrate 10 and the second substrate 20.
The first substrate 10 and the second substrate 20 are bonded together by the frame sealing glue 40, a first spacing region and a second spacing region are formed between the first substrate 10 and the second substrate 20 and in the non-display region AA, and a first height h1 of the first spacing region is greater than a second height h2 of the second spacing region.

Further, the first supporting structures 41 are supporting pillars, and before the frame sealing adhesive 40 is coated, the first supporting structures 41 are fabricated on the first substrate 10 and/or the second substrate 20, where the first supporting structures 41 correspond to the non-display area AA of the display panel. After the first substrate 10 and the second substrate 20 are bonded together, the first supporting structure 41 is wrapped in the frame sealing adhesive 40.

However, since the support balls 43 are mixed before the frame sealing adhesive 40 and coated on the substrate, the support balls 43 are also disposed in the first space region, and the support balls 43 can also be used to reduce the fluidity of the frame sealing adhesive 40 and prevent the frame sealing adhesive 40 from flowing around.
[ example two ]
Fig. 5 is a schematic perspective view illustrating a display panel having a sealant according to a second embodiment of the present invention. As shown in fig. 5, the display panel and the manufacturing method thereof according to the second embodiment of the present invention are substantially the same as those of the display panel and the manufacturing method according to the first embodiment (fig. 1 to 4), except that in this embodiment, the second supporting structure 42 is also a supporting column, i.e., the first supporting structure 41 and the second supporting structure 42 are both supporting columns. One end of the second supporting structure 42 is connected to the first substrate 10, and the other end of the second supporting structure 42 is abutted to the second substrate 20, i.e. a supporting column is fabricated on the first substrate 10 as the second supporting structure 42. Of course, in other embodiments, one end of the second supporting structure 42 is connected to the second substrate 20, and the other end of the second supporting structure 42 is abutted against the first substrate 10, i.e. a supporting column is fabricated on the second substrate 20 as the second supporting structure 42.
Preferably, the frame sealing adhesive 40 is provided with the supporting balls 43(SP), the height of the supporting balls 43 is less than or equal to the second height h2 of the second spacing region, although the first supporting structure 41 and the second supporting structure 42 support the first substrate 10 and the second substrate 20, the adding of the supporting balls 43 in the frame sealing adhesive 40 can prevent the frame sealing adhesive 40 from flowing around. Of course, in other embodiments, the frame sealing adhesive 40 does not need to be provided with the supporting balls 43.
Here, since the first support structure 41 and the second support structure 42 are support columns, the amount of compression needs to be considered for both the first support structure 41 and the second support structure 42. For example: under the condition that the height and the number of the first supporting structure 41 and the second supporting structure 42 are the same, the compression amount of the supporting columns with the diameter of 5um is 0.7um, and the compression amount of the supporting columns with the diameter of 17um is 0.2um, so that the offset of 0.5um can be improved under the condition that the initial height of the first supporting structure 41 and the initial height of the second supporting structure 42 are the same. Similarly, different numbers and heights can be selected to achieve the same effect.
In this embodiment, a method for manufacturing a display panel is further provided, in which the second supporting structures 42 are supporting pillars, and before the frame sealing adhesive 40 is coated, the second supporting structures 42 are manufactured on the first substrate 10 and/or the second substrate 20, and the second supporting structures 42 correspond to the non-display area AA of the display panel. After the first substrate 10 and the second substrate 20 are bonded together, the second supporting structure 42 is wrapped in the frame sealing adhesive 40.
It should be understood by those skilled in the art that the rest of the structure and the operation principle of the present embodiment are the same as those of the first embodiment, and are not described herein again.
The invention also provides a display device comprising the display panel.
