Description

Technical Field

[0001] This application relates to the field of display technology, and in particular to a display device and its display panel. Background Technology

[0002] Thin-film transistor liquid crystal display (TFT-LCD) panels typically consist of an upper substrate and a lower substrate, with conductive layers on both substrates connected by conductive gold balls. In current mass production using external expansion of PI (polyimide) liquid, both the sealant coating and the conductive gold ball placement are located on the PI film. Since the main component of the PI film is polyimide, an insulating film formed from a high-molecular polymer, when the conductive gold balls are located on the PI film, they need to pierce the PI film to conduct electricity between the ITO (indium tin oxide) layers of the upper and lower substrates. Coupled with batch-to-batch instability of the conductive gold balls, poor conductivity can easily occur, resulting in screen flickering.

[0003] Meanwhile, with the PI film shrinking inward, the frame adhesive coating and conductive gold ball dotting are both located on the substrate ITO film layer. At this time, the conductive gold ball has good conductivity, but due to the poor condition of the PI film edge surface, uneven brightness occurs around the pixel, which seriously affects the product yield and quality. Summary of the Invention

[0004] The main technical problem addressed by this application is to provide a display device and its display panel that solves the problems of poor conductivity of conductive gold balls and uneven display brightness in the prior art.

[0005] To address the aforementioned technical problems, the first technical solution provided in this application is: to provide a display panel having a display area and a non-display area, the display panel comprising:

[0006] Array substrate;

[0007] A color filter substrate is disposed opposite to the array substrate;

[0008] A frame adhesive, disposed between the color filter substrate and the array substrate and located in the non-display area, is used to encapsulate the display panel;

[0009] A conductor, fixed to the frame adhesive, is used to conduct electricity between the color filter substrate and the array substrate;

[0010] An alignment film is disposed on the side of the color filter substrate near the array substrate;

[0013] The window is a notch structure; in a direction parallel to the color filter substrate, the opening of the notch structure is oriented away from the display area.

[0014] In the direction parallel to the color filter substrate, the cross-sectional area of ​​the notch structure gradually increases in the direction away from the display area.

[0015] The notch structure connects to the side of the alignment film away from the display area.

[0016] Wherein, in the direction parallel to the color filter substrate, the junction between the notch structure and the alignment film is an arc or a rounded corner.

[0017] The conductor is located on the side of the frame adhesive close to the display area, and at least partially overlaps with the frame adhesive in a direction parallel to the color filter substrate.

[0018] The array also includes a first conductive layer and a second conductive layer. The first conductive layer is disposed on the side of the alignment film near the color filter substrate, and the second conductive layer is disposed on the side of the array substrate near the color filter substrate. One end of the conductor near the color filter substrate passes through the window and is electrically connected to the first conductive layer, and the other end is electrically connected to the second conductive layer.

[0019] The color filter substrate includes a black matrix layer; the window is disposed in the non-display area and corresponds to the black matrix layer.

[0020] To solve the above-mentioned technical problems, the second technical solution provided by this application is: to provide a display device, the display device including a backlight module and the above-mentioned display panel.

[0021] The beneficial effects of this application are as follows: Unlike existing technologies, this application provides a display device and its display panel. The display panel has a display area and a non-display area, and includes an array substrate, a color filter substrate, a frame adhesive, a conductor, and an alignment film.

By providing a window on the alignment film, the end of the conductor near the color filter substrate can directly conduct electricity with the color filter substrate through the window, so that the conductor does not need to pierce the alignment film, and can directly conduct electricity with the color filter substrate, thereby improving the conductivity between the color filter substrate and the conductor.

[0038] Please see Figure 1 , Figure 1 This is a schematic diagram of an embodiment of the display device provided in this application.

[0039] This application provides a display device 300, which includes a backlight module 200 and a display panel 100. The display panel 100 is disposed opposite to the backlight module 200. The backlight module 200 provides a backlight source for the display panel 100. The display device 300 may also include one or more of the following components: a memory, a power supply component, a processing component, a multimedia component, an audio component, an input / output (I / O) interface, a sensor component, and a communication component. The specific structure and function of these components are the same as or similar to those in the prior art, and specific details can be found in the prior art, which will not be repeated here.

[0040] The display device 300 may be a computer, digital broadcasting terminal, messaging device, game console, medical device, fitness equipment, personal digital assistant, etc., and this application does not limit it.

[0041] Please see Figure 2 , Figure 2 This is a schematic diagram of the structure of an embodiment of the display panel provided in this application.

[0042] This application provides a display panel 100, which is a liquid crystal panel. The display panel 100 has a display area 101 and a non-display area 102. The non-display area 102 can be located on one or both sides of the display area 101, or it can surround the display area 101. The display area 101 is used to house structures such as driving circuits and signal lines. The non-display area 102 is used to house structures such as scanning circuits, test circuits, and display control circuits. In this embodiment, the non-display area 102 surrounds the display area 101.

[0043] The display panel 100 includes a color filter substrate 1, an array substrate 2, a frame adhesive 3, a conductor 4, an alignment film 5, a first conductive layer 6, a second conductive layer 7, and a liquid crystal layer 8. The array substrate 2 is disposed opposite to the color filter substrate 1. The frame adhesive 3 is disposed between the color filter substrate 1 and the array substrate 2 and located in the non-display area 102, for encapsulating the display panel 100. The conductor 4 is fixed to the frame adhesive 3 for conducting electricity between the color filter substrate 1 and the array substrate 2. The alignment film 5 is disposed on the side of the color filter substrate 1 near the array substrate 2, and on the side of the array substrate 2 near the color filter substrate 1. The first conductive layer 6 is disposed on the side of the alignment film 5 near the color filter substrate 1, and the second conductive layer 7 is disposed on the side of the array substrate 2 near the color filter substrate 1. The liquid crystal layer 8 is located between the color filter substrate 1 and the array substrate 2.

[0044] The color filter substrate 1 includes a first substrate 11, a filter layer 12, a black matrix layer 13, and a first polarizer 14. The filter layer 12 is disposed on the same layer as the black matrix layer 13 and is located on the side of the first substrate 11 closest to the array substrate 2. The filter layer 12 includes red, blue, and green color filters. The black matrix layer 13, using a material with high light-shielding properties, separates the red, green, and blue primary colors in the filter layer 12 and prevents light leakage, thereby improving the contrast of each color block. The filter layer 12 enables full-color display of the liquid crystal display device 300. The first polarizer 14 is disposed on the side of the color filter substrate 1 away from the array substrate 2 and is used to control the deflection direction of the light beam. The color filter substrate 1 may also include other functional layers, which are not limited here. In other embodiments, the filter layer 12 may also include color filters of other colors.

[0045] The array substrate 2 includes a second substrate 21, a thin-film transistor (not shown), and a second polarizer 22. The thin-film transistor is disposed on the side of the second substrate 21 closer to the color filter substrate 1. The second polarizer 22 is disposed on the side of the array substrate 2 away from the array substrate 2 and is used to control the deflection direction of the light beam. The polarization directions of the first polarizer 14 and the second polarizer 22 are orthogonal and perpendicular, and can effectively control the polarization direction of a specific light beam. The array substrate 2 may also include other functional layers, which are not limited here. The materials of the first substrate 11 and the second substrate 21 are generally alkali-free borosilicate glass with excellent mechanical properties, heat resistance, and chemical corrosion resistance. Other materials may also be used for the first substrate 11 and the second substrate 21, which are not limited here.

[0046] The liquid crystal layer 8 includes liquid crystal, which acts as a light valve in the display device 300, controlling the brightness of transmitted light to achieve the effect of information display. The frame adhesive 3 is disposed in the non-display area 102, surrounding the display area 101. The frame adhesive 3 bonds the array substrate 2 and the color filter substrate 1 together, maintaining a certain gap to seal the liquid crystal and prevent leakage, while also preventing external contaminants from entering the liquid crystal layer 8.

[0047] Conductor 4 is fixed to frame adhesive 3 and is used to conduct electricity between color filter substrate 1 and array substrate 2. One end of conductor 4 near color filter substrate 1 abuts against and is electrically connected to the first conductive layer 6, and the other end near array substrate 2 abuts against and is electrically connected to the second conductive layer 7. Conductor 4 conducts electricity between color filter substrate 1 and array substrate 2 by connecting the first conductive layer 6 and the second conductive layer 7. Conductor 4 is located on the side of frame adhesive 3 near display area 101 and at least partially overlaps with frame adhesive 3 in a direction parallel to color filter substrate 1. That is, conductor 4 is at least partially embedded in the side of frame adhesive 3 closest to display area 101. Multiple conductors 4 are arranged at intervals. Conductor 4 can be at least one of a sphere, cone, cuboid, or cube. Conductor 4 can be made of gold, silver, copper, or aluminum, or a sphere plated with gold, silver, copper, or aluminum; no limitation is imposed, and the selection is based on actual needs. In this embodiment, conductor 4 has an elliptical structure. Both the first conductive layer 6 and the second conductive layer 7 are ITO. In other embodiments, the materials of the first conductive layer 6 and the second conductive layer 7 may be the same or different. The first conductive layer 6 and the second conductive layer 7 may also be made of other materials.

[0048] Please see Figures 2 to 5 , Figure 3 This is a top view schematic diagram of an embodiment of the frame adhesive, the first alignment film, and the conductor provided in this application. Figure 4 This is a schematic diagram of the structure of the first embodiment of the first alignment film provided in this application. Figure 5 yes Figure 4 A schematic diagram of the cross-sectional structure at point AA.

[0049] The alignment film 5 disposed on the side of the color filter substrate 1 near the array substrate 2 is defined as the first alignment film 51, and the alignment film 5 disposed on the side of the array substrate 2 near the color filter substrate 1 is defined as the second alignment film 55. The second alignment film 55 is disposed on the side of the frame adhesive 3 and the conductor 4 near the display area 101, and the side of the conductor 4 near the array substrate 2 is directly electrically connected to the second conductive layer 7. The first alignment film 51 is provided with at least one window 52, ​​which penetrates the alignment film 5 in a direction perpendicular to the color filter substrate 1. The window 52 is disposed in the non-display area 102 and corresponds to the black matrix layer 13. The black matrix layer 13 is partially located in the display area 101 and partially located in the non-display area 102. The orthographic projection of the black matrix layer 13 located in the non-display area 102 onto the array substrate 2 covers the orthographic projection of the frame adhesive 3 onto the array substrate 2. It should be noted that the first alignment film 51 of this application is manufactured in one process, and the window 52 of the first alignment film 51 is also formed during the preparation of the first alignment film 51. Compared to the prior art where grooves or holes are fabricated on the first alignment film 51 after coating, the design of the first alignment film 51 and the window 52 in this application is completed together, which simplifies the fabrication process and makes the thickness of the first alignment film 51 more uniform.

[0050] One end of the conductor 4, near the color filter substrate 1, is located within the window 52 and is directly connected to the color filter substrate 1. In other words, the end of the conductor 4 near the color filter substrate 1 passes through the window 52 and directly contacts the first conductive layer 6 to achieve electrical connection. Compared to a design where the end of the conductor 4 near the color filter substrate 1 directly abuts against the first alignment film 51, requiring the conductor 4 to pierce the first alignment film 51 before contacting the first conductive layer 6 during display panel 100 operation, this application provides a window 52 on the first alignment film 51, allowing the conductor 4 to pass through the window 52 and directly contact the first conductive layer 6. This design provides better conductivity between the conductor 4 and the first conductive layer 6, avoiding flickering issues caused by poor conductivity and improving the display effect of the display panel 100.

[0051] The portion of the adhesive 3 near the color filter substrate 1 is located within the window 52. That is, the adhesive 3 surrounding the conductor 4 is located within the window 52. This can be understood as follows: in the direction parallel to the color filter substrate 1, the cross-sectional area of ​​the window 52 is larger than the cross-sectional area of ​​the end of the conductor 4 near the color filter substrate 1, allowing the end of the conductor 4 near the color filter substrate 1 to directly contact the first conductive layer 6 without piercing the first alignment film 51. Simultaneously, the portion of the adhesive 3 connecting the conductor 4 is located within the window 52, ​​allowing it to directly contact the first conductive layer 6. Compared to a design where the entire side of the adhesive 3 near the color filter substrate 1 contacts the first alignment film 51, this design provides a stronger connection between the adhesive 3 and the color filter substrate 1, improving the adhesion between them.

[0052] Window 52 is a through hole ( Figures 1 to 5 (Not shown) and / or notch structure 53. That is, the first alignment film 51 may only have through holes, or only have notch structure 53, or both through holes and notch structure 53. During the coating process of the first alignment film 51, the position of the window 52 is reserved in advance. The position of the reserved window 52 is larger than the actual position of the window 52 to prevent the cross-sectional area of ​​the window 52 finally formed on the first alignment film 51 in the direction parallel to the color filter substrate 1 from being too small, so that the end of the conductor 4 near the color filter substrate 1 can completely pass through the window 52 and abut against the first conductive layer 6. The material used to prepare the first alignment film 51 is PI (Polyimide) liquid. Because the PI liquid is liquid during coating, it has fluidity and, due to surface tension, flows towards the reserved window 52. This causes the cross-sectional area of ​​the reserved window 52 to decrease in the direction parallel to the color filter substrate 1. Furthermore, in the direction parallel to the color filter substrate 1, the cross-section of the final window 52 is different from that of the reserved window 52. The final window 52 has an arc-shaped cross-section, and the reserved window 52 is preferably rectangular. Further, in the process of preparing the first alignment film 51 in this application, no mask or other structures are used to obscure the position of the reserved window 52. In other words, there will be no accumulation of PI liquid around the window 52, ​​which would affect the uneven thickness of the first alignment film 51 around the window 52. Therefore, the uneven thickness of the first alignment film 51 at the edge of the display area 101 will not cause uneven brightness of the displayed image. It should be understood that in this application, the window 52 is formed during the coating process of PI liquid, and a mask is not made at the reserved window 52 position. Due to the surface tension of PI liquid, the window 52 cannot be a regular rectangular or square structure.

[0053] When window 52 is a notch structure 53, the opening of the notch structure 53 is positioned away from the display area 101 in the direction parallel to the color filter substrate 1. The notch structure 53 connects to the side of the first alignment film 51 away from the display area 101. In the direction parallel to the color filter substrate 1, the junction of the notch structure 53 and the first alignment film 51 is an arc or a rounded corner. Specifically, the cross-section of the notch structure 53 in the direction parallel to the color filter substrate 1 is a structure composed of arc segments, including a first arc segment 531, a second arc segment 532, and a third arc segment 533 connecting the first arc segment 531 and the second arc segment 532. The third arc segment 533 is U-shaped, and the third arc segment 533 is positioned close to the display area 101, while the first arc segment 531 and the second arc segment 532 are positioned away from the display area 101. Due to the proximity of the third arc segment 533 to the display area 101 and the surface tension of the PI liquid, the PI liquid on the outside of the notch structure 53 near the third arc segment 533 converges towards the center of the notch structure 53, forming a U-shape. Because the first arc segment 531 and the second arc segment 532 are located away from the display area 101 and at the edge of the first alignment film 51, and due to the surface tension of the PI liquid, the PI liquid near the first arc segment 531 on the outside of the notch structure 53 converges away from the second arc segment 532, and the PI liquid near the second arc segment 532 on the outside of the notch structure 53 converges away from the first arc segment 531. In other words, in the direction parallel to the color filter substrate 1, the cross-sectional area of ​​the notch structure 53 gradually increases in the direction away from the display area 101. When the window 52 is a through hole, the cross-sectional area of ​​the through hole in the direction parallel to the color filter substrate 1 is an ellipse or an irregular circle. Due to the surface tension of the PI liquid, the inner wall of the window 52 is also an arc surface. That is, in the direction perpendicular to the color filter substrate 1, the inner wall of the window 52 is not a regular cross-section, but an arc surface like the outer surface of a water droplet; that is, in the direction perpendicular to the inner wall of the window 52, ​​the inner wall has an arc-shaped protrusion. Specifically, as... Figure 5 As shown, the inner wall of the notch structure 53 corresponding to the third arc segment 533 is an arc surface, and the inner wall of the notch structure 53 protrudes towards the direction close to the first arc segment 531 and the second arc segment 532. It should be understood that when the window 52 is a through hole, the annular inner wall of the through hole protrudes towards the direction close to the center line of the through hole. In this embodiment, the window 52 is a notch structure 53 and is located in the non-display area 102. There are multiple notch structures 53, which are disposed on opposite sides of the first alignment film 51 and symmetrically disposed on both sides of the first alignment film 51. This facilitates the coating of PI liquid to form a shaped first alignment film 51 in one process, simplifying the preparation process.

[0054] Please see Figures 6a to 6c , Figure 6a This is a schematic diagram of the structure of the second embodiment of the first alignment film provided in this application. Figure 6bThis is a structural schematic diagram of the third embodiment of the first alignment film provided in this application. Figure 6c This is a schematic diagram of the structure of the fourth embodiment of the first alignment membrane provided in this application.

[0055] In other embodiments, the window 52 may be disposed on one side or each side of the first alignment film 51. The window 52 on the first alignment film 51 may be a through hole 54, or a through hole 54 and a notch structure 53. The number of windows 52 on each side of the first alignment film 51 may be the same or different. The windows 52 on opposite sides of the first alignment film 51 may be symmetrically arranged or asymmetrically arranged. The size of the window 52 is not limited, as long as the end of the conductor 4 near the color filter substrate 1 can completely pass through the window 52 and abut against the first conductive layer 6, without affecting the display effect of the display panel 100. It should be noted that the embodiments in this application only illustrate some examples and do not represent that the structure of the first alignment film 51 and the window 52 is limited to this.

[0056] This application provides a display panel 100, which has a display area 101 and a non-display area 102. The display panel 100 includes an array substrate 2, a color filter substrate 1, a frame adhesive 3, a conductor 4, and an alignment film 5. The color filter substrate 1 is disposed opposite to the array substrate 2; the frame adhesive 3 is disposed between the color filter substrate 1 and the array substrate 2 and is located in the non-display area 102 for encapsulating the display panel 100; the conductor 4 is fixed to the frame adhesive 3 for conducting electricity between the color filter substrate 1 and the array substrate 2; the alignment film 5 is disposed on the side of the color filter substrate 1 near the array substrate 2; wherein, the alignment film 5 has at least one window 52, ​​the window 52 penetrates the alignment film 5 in a direction perpendicular to the color filter substrate 1, and the inner sidewall of the window 52 is curved. By providing a window 52 on the alignment film 5, the end of the conductor 4 near the color filter substrate 1 can be directly connected to the color filter substrate 1 through the window 52, ​​so that the conductor 4 does not need to pierce the alignment film 5 and can be directly connected to the color filter substrate 1, thereby improving the conductivity between the color filter substrate 1 and the conductor 4.

[0057] The above are merely embodiments of this application and do not limit the scope of patent protection of this application. Any equivalent structural or procedural changes made using the content of this application’s specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of this application.
