Detailed Description
To further explain the display panel and the display device provided by the embodiments of the present invention, the following description is made in detail with reference to the accompanying drawings.
With the development of display technologies, users have increasingly high quality requirements for display panels in mobile terminals such as mobile phones and tablet computers, and display panels with good visual effects and high reliability gradually become a main development trend. In order to ensure that the reliability of the display panel can meet the increasing quality requirements of users, after the display panel is prepared, some higher-requirement mechanical performance tests, such as a compression test, a drop test and the like, are generally required to be performed on the display panel, so as to optimize the display panel according to the performance of the display panel in each test.
The structure of the conventional liquid crystal display panel is shown in fig. 1, and after the liquid crystal display panel is subjected to multiple times of higher-requirement mechanical performance tests, the reason for the poor reliability is found to be that: because there is a single-layer portion independently floating inside, that is, the portion of the array substrate 4 where the bonding region C is located. After the integrated Circuit chip (IC) 71 and the Flexible Printed Circuit (FPC) 72 are bonded to the bonding region C, although the gap is filled with the filler 8 such as foam or silicone adhesive, due to the presence of the IC and the FPC on the bonding region C, the filler 8 is difficult to completely fill the gap between the bonding region C and the cover plate 1, and the filler 8 is difficult to be accurately filled due to the influence of the precision of the filling equipment, i.e., the filling misalignment of the filler 8 may occur, so that the bonding region C of the array substrate 4 is difficult to be uniformly and stably supported by the filler 8, and therefore, when a mechanical performance test with a higher requirement is performed on the liquid crystal display panel, the bonding region C of the array substrate 4 is easily damaged due to uneven force, or shake in the direction perpendicular to the surface of the array substrate 4 under the action of external force, thereby affecting the reliability of the liquid crystal display panel.
In order to effectively improve the reliability of the display panel, please refer to fig. 2 and fig. 3, an embodiment of the present invention provides a display panel, which includes an array substrate 4 and a color film substrate 6 sequentially arranged from a display side a of the display panel to a back side B of the display panel; the bonding region C of the array substrate 4 is located on the surface of the array substrate 4 opposite to the display side, and the bonding region C is not covered by the color film substrate 6.
The array substrate 4 and the color film substrate 6 are arranged in parallel and opposite to each other. One side of the array substrate 4, which faces away from the color film substrate 6, is a display side a of the display panel, that is, the side of the display panel where the cover plate 1 is arranged; the side of the color film substrate 6 facing away from the array substrate 4 is a back side B of the display panel, that is, the side of the display panel opposite to the backlight module.
The embodiment of the utility model provides a display panel sets gradually array substrate 4 and various membrane substrate 6 from display panel's demonstration side A to display panel's dorsal part B for array substrate 4 bind district C and be located array substrate 4 surface of demonstration side A dorsad, array substrate 4 is towards the surface of various membrane substrate 6 promptly, and is not covered by various membrane substrate 6. Thus, by using a fault gap between the color film substrate 6 and the array substrate 4 binding region C, the binding circuit of the array substrate 4 binding region C can be accommodated without reserving a space on the side of the array substrate 4 facing the display side a, and therefore, the entire surface of the array substrate 4 facing the display side a can be directly and fixedly connected with the cover plate 1 arranged on the display side a, or indirectly and fixedly connected, for example, fixedly connected with the cover plate 1 through an optical element with a planar structure; therefore, the fixed connection between the array substrate 4 binding area C and the cover plate 1 is realized, and the fixed supporting effect of the cover plate 1 on the array substrate 4 binding area C can be utilized to ensure that the binding area C of the array substrate 4 can not easily shake or be damaged due to the action of external force when the binding area C faces higher requirements on mechanical performance test, so that the reliability of the display panel is improved.
Furthermore, the embodiment of the utility model provides a display panel need not to use fillers such as bubble cotton or silicone adhesive to carry out the space filling, not only can reduce the kind of display panel production raw and other materials, practices thrift manufacturing cost, can also reduce display panel's preparation process to improve display panel's production efficiency.
The cover plate 1 is disposed on a side of the array substrate 4 facing the display side a, and may be a glass cover plate for display or a glass cover plate for touch display. The fixed connection between the surface of the array substrate 4 facing the display side a and the cover plate 1 can be implemented in various ways, such as: the surface of the array substrate 4 facing the display side a is directly bonded to the cover plate 1, or the surface of the array substrate 4 facing the display side a is bonded to the cover plate 1 through some optical elements of a planar structure, etc., which should be determined according to the structure of the display panel.
For example, referring to fig. 2, the surface of the array substrate 4 facing the display side a is directly bonded to the cover plate through the optical transparent adhesive layer 2. The embodiment of the utility model provides a through optics transparent adhesive tape layer 2 firmly bond array substrate 2 to apron 1 on, can utilize apron 1 to array substrate 4's fixed stay, ensure that array substrate 4's the district C of binding can not rock easily or damaged because of the effect of external force, be favorable to improving display panel's reliability.
The above optical transparent adhesive layer 2 may cover the entire surface of the array substrate 4 facing the display side a, and is specifically represented as: the size of each edge of the plane of the optical transparent adhesive layer 2 is equal to the size of the corresponding edge of the plane of the array substrate 4; or, the size of each side of the plane of the optical transparent adhesive layer 2 is slightly larger than the size of the corresponding side of the plane of the array substrate 4, and the optical transparent adhesive layer 2 is properly expanded relative to the array substrate 4. The above-mentioned edge sizes of the plane of the optical transparent adhesive layer 2 generally refer to the edge sizes of the orthographic projection of the optical transparent adhesive layer 2 on the array substrate 4, such as: when the orthographic projection of the optical transparent adhesive layer 2 on the array substrate 4 is a rectangle, the dimensions of each side of the plane of the optical transparent adhesive layer 2 include the dimensions of each long side and each wide side of the rectangle.
Of course, the above-mentioned optical transparent adhesive layer 2 may also partially cover the surface of the array substrate 4 facing the display side a, which is specifically represented as: the size of each side of the plane of the optical transparent adhesive layer 2 is slightly smaller than the size of the corresponding side of the plane of the array substrate 4, and the optical transparent adhesive layer 2 is properly retracted relative to the array substrate 4. It can be understood that when the optical transparent adhesive layer 2 partially covers the surface of the array substrate 4 facing the display side a, the size of each side of the plane of the optical transparent adhesive layer 2 cannot be too small, and the fixed connection between the array substrate 4 and the cover plate 1 should be realized as a limitation.
For example, referring to fig. 3, the display panel is a liquid crystal display panel; a liquid crystal layer 5 is sandwiched between the array substrate 4 and the color film substrate 6. The surface of the array substrate 4 facing the display side a is fixedly provided with a first polarizer 31, and the first polarizer 31 is adhered to the cover plate 1 through an optical transparent adhesive layer 2. A second polarizer 32 is fixedly arranged on the surface of the color film substrate 6 opposite to the display side a. The Liquid Crystal layer 5 may be integrated in the array substrate 4 in advance, and may be in an integrated structure of an LCD (Liquid Crystal Display) array substrate.
The first polarizer 31 is generally made of a thin plate structure, and the mounting surface thereof is generally provided with an adhesive, so that the first polarizer 31 can be firmly adhered to the array substrate 4. The embodiment of the utility model provides a firmly bond first polaroid 31 on apron 1 through optics transparent adhesive layer 2, and first polaroid 31 firmly bonds with array substrate 4, utilizes apron 1 to the fixed stay of first polaroid 31 like this to and the fixed stay of first polaroid 31 to array substrate 4, can ensure that array substrate 4 bind district C and can not rock easily or damage because of the effect of external force, be favorable to improving display panel's reliability.
In the liquid crystal display panel provided in the above embodiment, the first polarizer 31 may cover the entire surface of the array substrate 4 facing the display side a, which is specifically represented by: the dimensions of each side of the plane of the first polarizer 31 are equal to the dimensions of the corresponding side of the plane of the array substrate 4, as shown in fig. 3; or, the size of each side of the plane of the first polarizer 31 is slightly larger than the size of the corresponding side of the plane of the array substrate 4, and the first polarizer 31 is properly extended with respect to the array substrate 4, as shown in fig. 4a and 4 c. The dimensions of the above-mentioned sides of the plane of the first polarizer 31 generally refer to the dimensions of the sides of the first polarizer 31 orthographically projected on the array substrate 4, such as: when the orthographic projection of the first polarizing plate 31 on the array substrate 4 is a rectangle, the dimensions of each side of the plane of the first polarizing plate 31 include the dimensions of each long side and each wide side of the rectangle.
The first polarizer 31 may also partially cover the surface of the array substrate 4 facing the display side a, and is specifically represented as: the dimensions of each side of the plane of the first polarizer 31 are slightly smaller than the dimensions of the corresponding side of the plane of the array substrate 4, and the first polarizer 31 is properly retracted with respect to the array substrate 4, as shown in fig. 4b and 4 d. It is understood that, although the thickness of the first polarizer 31 is small, when the first polarizer 31 partially covers the surface of the array substrate 4 facing the display side a, the size of each side of the plane of the first polarizer 31 cannot be too small to avoid a large gap between the surface of the array substrate 4 facing the display side a and the cover plate 1. Of course, if the dimensions of the sides of the plane of the first polarizer 31 are too small, that is, there may be a large gap between the surface of the array substrate 4 facing the display side a and the cover plate 1, in the subsequent assembly process of the display panel, the gap needs to be sealed by using a sealing adhesive, a sealing case, or the like, so as to ensure the reliability of the finished display panel.
Similarly, when the first polarizer 31 is adhered to the cover plate 1 through the optical transparent adhesive layer 2, the optical transparent adhesive layer 2 may cover the entire surface of the first polarizer 31 facing the display side a, which is specifically represented as: the size of each side of the plane of the optical transparent adhesive layer 2 is equal to the size of the corresponding side of the plane of the first polarizer 31, as shown in fig. 4a and 4 b; or, the size of each side of the plane of the optical transparent adhesive layer 2 is slightly larger than the size of the corresponding side of the plane of the first polarizer 31, and the optical transparent adhesive layer 2 is properly expanded relative to the first polarizer 31. Of course, the above-mentioned optical transparent adhesive layer 2 may also partially cover the surface of the first polarizer 31 facing the display side a, which is specifically represented as: each side dimension of the plane of the optical transparent adhesive layer 2 is slightly smaller than the corresponding side dimension of the plane of the first polarizer 31, and the optical transparent adhesive layer 2 is properly retracted relative to the first polarizer 31, as shown in fig. 4c and 4 d. It is understood that when the optical transparent adhesive layer 2 partially covers the surface of the first polarizer 31 facing the display side a, the size of each side of the plane of the optical transparent adhesive layer 2 cannot be too small, and the fixed connection between the first polarizer 31 and the cover plate 1 should be realized as a limitation.
Please refer to fig. 3, in the display panel provided in the above embodiment, the bonding region C of the array substrate 4 is provided with a bonding circuit, which generally includes: an Integrated Circuit (IC) 71 and/or a Flexible Printed Circuit (FPC) 72. In order to protect the bonding area C of the array substrate 4 and the conductive connection between the bonding area C and the bonding circuit from water, a glue protection layer 73 is usually further disposed on the bonding area C of the array substrate 4, and the glue protection layer 73 may not cover or partially cover the bonding circuit according to actual needs, for example, the glue protection layer 73 does not cover the IC, and/or the glue protection layer 73 partially covers the FPC. The material for the adhesive protective layer 73 can be selected according to actual needs.
Illustratively, the array substrate 4 generally includes a Thin Film Transistor (TFT) array substrate, or an LCD-TFT array substrate. The bonding area of the TFT array substrate is generally bonded with an FPC (flexible printed circuit), and the display function of the TFT array substrate can be controlled through the FPC. For the LCD-TFT array substrate, the binding region can adopt a COG (chip on glass) structure, namely, the IC and the FPC are respectively bound in the binding region of the LCD-TFT array substrate; or a COF (chip On film) structure is adopted, namely, an IC is integrated in the FPC, and then the integrated FPC is bound in a binding region of the LCD-TFT array substrate; thereby driving the LCD in the LCD-TFT array substrate through the IC and controlling the display function of the LCD-TFT array substrate through the FPC.
It should be added that, referring to fig. 3, 5 and 6, when the flexible circuit board 72 is included in the binding circuit, most of the main body of the flexible circuit board 72 extends out of the edge of the array substrate, so in order to ensure stable binding of the flexible circuit board 72 in the binding region C of the array substrate 4, the flexible circuit board 72 is generally extended out of the edge of the array substrate 4 and the surface opposite to the display side a is adhered to the edge of the corresponding array substrate by a line adhesive 74. A line adhesive 74 is generally applied in a line shape, and the surface of the flexible circuit board 722 extending beyond the edge of the array substrate 4 and opposite to the display side a is firmly adhered to the edge of the array substrate 4 to assist in fixing the flexible circuit board 72. Of course, the above bonding structure of the line glue and the edge of the array substrate is not only suitable for the flexible circuit board, but also suitable for other components in the binding circuit under the same condition.
Referring to fig. 7 and 8, when the display panel provided in the above embodiment is manufactured, the manufacturing method includes:
in step S1, an array substrate is provided. The array substrate generally includes a Thin Film Transistor (TFT) array substrate, or an LCD-TFT array substrate.
Step S2, a color film substrate is disposed on one side of the array substrate where the bonding region is disposed, and the color film substrate does not cover the bonding region. When the array substrate is an LCD-TFT array substrate, the color film substrate is generally disposed opposite to the LCD-TFT array substrate.
Step S3, a cover plate is disposed on a side of the array substrate opposite to the color filter substrate, and the surface of the array substrate opposite to the color filter substrate is fixedly connected to the cover plate. The cover plate generally includes a glass cover plate for display or a glass cover plate for touch display.
The embodiment of the utility model provides a display panel's preparation method for the display panel that the above-mentioned embodiment of preparation provided, consequently, the beneficial effect that its can reach can refer to the beneficial effect that the above-mentioned embodiment provided corresponds display panel, and the here is no longer repeated.
It should be noted that the fixed connection between the surface of the array substrate facing away from the color filter substrate and the cover plate may be implemented in various ways, for example: the surface of the array substrate, which faces away from the color film substrate, is directly bonded with the cover plate, or indirectly bonded with the cover plate, and the like, which is specifically determined according to the structure of the display panel.
For example, in step S3, the step of providing the cover plate on the side of the array substrate opposite to the color filter substrate may include any one of the following two ways.
Firstly, an optical transparent adhesive layer is pasted on the surface of the array substrate, which is opposite to the color film substrate, and the optical transparent adhesive layer is adhered to the cover plate. The embodiment of the utility model provides a through optics transparent adhesive layer firmly bond array substrate to the apron on, can utilize the apron to array substrate's fixed stay, ensure that array substrate's the district of binding can not rock easily or damaged because of the effect of external force, be favorable to improving display panel's reliability.

The dimensions of the sides of the plane of the optical transparent adhesive layer generally refer to the dimensions of the sides of the orthographic projection of the optical transparent adhesive layer on the array substrate, such as: when the orthographic projection of the optical transparent adhesive layer on the array substrate is a rectangle, the size of each side of the plane of the optical transparent adhesive layer comprises the size of each long side and the size of each wide side of the rectangle.
Of course, the optical transparent adhesive layer may also partially cover the surface of the array substrate facing away from the color film substrate, which is specifically represented as: the size of each edge of the plane of the optical transparent adhesive layer is slightly smaller than the size of the corresponding edge of the plane of the array substrate, and the optical transparent adhesive layer is properly retracted relative to the array substrate. It can be understood that when the optical transparent adhesive layer partially covers the surface of the array substrate facing away from the color film substrate, the size of each side of the plane of the optical transparent adhesive layer cannot be too small, and the fixed connection between the array substrate and the cover plate should be realized as a limiting condition.
Secondly, when the array substrate is an LCD-TFT array substrate, that is, the display panel is a liquid crystal display panel, a first polarizer is attached to a surface of the array substrate opposite to the color filter substrate, for example, in step S31 in fig. 8; attaching a second polarizer to the surface of the color film substrate opposite to the array substrate, for example, in step S32 in fig. 8; an optical transparent adhesive layer is attached to a surface of the first polarizer opposite to the array substrate, and the optical transparent adhesive layer is attached to the cover plate, for example, in step S36 in fig. 8.
The first polarizer is usually in a thin plate structure, and the mounting surface of the first polarizer is generally provided with adhesive; when the first polarizer is attached to the surface of the array substrate, which is opposite to the color film substrate, the first polarizer can be firmly adhered to the array substrate. The embodiment of the utility model provides a firmly bond first polaroid and array substrate, and firmly bond first polaroid to the apron through optics transparent adhesive layer, utilize the apron to the fixed stay of first polaroid like this to and the fixed stay of first polaroid to array substrate, can ensure that array substrate's the district of binding can not rock easily or damage because of the effect of external force, be favorable to improving display panel's reliability.
The first polarizer can cover the whole surface of the array substrate, which is opposite to the color film substrate, and the first polarizer is specifically represented as follows: the size of each side of the first polaroid plane is equal to the size of the corresponding side of the array substrate plane; or, the size of each side of the first polarizer plane is slightly larger than the size of the corresponding side of the array substrate plane, and the first polarizer is properly expanded relative to the array substrate. The dimensions of the sides of the plane of the first polarizer generally refer to the dimensions of the sides of the orthographic projection of the first polarizer on the array substrate, such as: when the orthographic projection of the first polarizer on the array substrate is a rectangle, the size of each side of the first polarizer plane comprises the size of each long side and the size of each wide side of the rectangle.
The first polarizer can also partially cover the surface of the array substrate, which faces away from the color film substrate, and the first polarizer is specifically represented as follows: the size of each side of the first polaroid plane is slightly smaller than the size of the corresponding side of the array substrate plane, and the first polaroid is properly retracted relative to the array substrate. It can be understood that, although the thickness of the first polarizer is smaller, when the first polarizer partially covers the surface of the array substrate facing away from the color filter substrate, the size of each side of the first polarizer plane cannot be too small, so as to avoid a large gap between the surface of the array substrate facing away from the color filter substrate and the cover plate. Of course, if the dimensions of the edges of the first polarizer plane are too small, that is, a large gap may exist between the surface of the array substrate facing away from the color filter substrate and the cover plate, in the subsequent assembly process of the display panel, the gap needs to be encapsulated by using an encapsulation adhesive, an encapsulation shell, and the like, so as to ensure the reliability of the finished display panel.
Similarly, when the first polarizer is bonded to the cover plate through the optical transparent adhesive layer, the optical transparent adhesive layer may cover the entire surface of the first polarizer facing away from the array substrate, which is specifically represented as: the size of each edge of the plane of the optical transparent adhesive layer is equal to the size of the corresponding edge of the plane of the first polaroid; or, the size of each side of the plane of the optical transparent adhesive layer is slightly larger than the size of the corresponding side of the plane of the first polaroid, and the optical transparent adhesive layer is properly expanded relative to the first polaroid. Of course, the optical transparent adhesive layer may also partially cover the surface of the first polarizer opposite to the array substrate, which is specifically represented as: the size of each edge of the plane of the optical transparent adhesive layer is slightly smaller than the size of the corresponding edge of the plane of the first polaroid, and the optical transparent adhesive layer is properly retracted relative to the first polaroid. It can be understood that, when the optical transparent adhesive layer partially covers the surface of the first polarizer opposite to the array substrate, the size of each side of the plane of the optical transparent adhesive layer is not too small, and the fixed connection between the first polarizer and the cover plate should be realized as a limiting condition.
Please refer to fig. 8, in the method for manufacturing a display panel according to the above embodiment, before the optical transparent adhesive layer is attached, a bonding circuit may be disposed in the bonding region, for example, S33 in fig. 8; coating a glue protection layer on the surface of the binding area which is not covered by the binding circuit so as to perform waterproof protection on the binding area of the array substrate by using the glue protection layer; or coating adhesive protection layers on the surfaces of the binding regions which are not covered by the binding circuit and part of the surfaces of the binding circuit so as to carry out waterproof protection on the binding regions of the array substrate and the conductive connection between the binding regions of the array substrate and the binding circuit by using the adhesive protection layers; such as S34 in fig. 8. The above binding circuit generally includes: an Integrated Circuit (IC) chip and/or a Flexible Printed Circuit (FPC).
Illustratively, the array substrate generally includes a TFT array substrate, or an LCD-TFT array substrate. The bonding area of the TFT array substrate is generally bonded with an FPC (flexible printed circuit), and the display function of the TFT array substrate is controlled through the FPC. For the LCD-TFT array substrate, the binding region can adopt a COG (chip on glass) structure, namely, the IC and the FPC are respectively bound in the binding region of the LCD-TFT array substrate; or a COF (chip On film) structure is adopted, namely, an IC is integrated in the FPC, and then the integrated FPC is bound in a binding region of the LCD-TFT array substrate; thereby driving the LCD in the LCD-TFT array substrate through the IC and controlling the display function of the LCD-TFT array substrate through the FPC.
It is to be supplemented that, when the binding circuit includes a flexible circuit board, most of the flexible circuit board body extends out of the edge of the array substrate, so that, in order to ensure stable binding of the flexible circuit board in the binding region of the array substrate, the flexible circuit board generally extends out of the edge of the array substrate and faces the surface of the cover plate, and is bonded with the edge of the corresponding array substrate through a line adhesive; namely, a line glue is coated at the joint of the surface of the flexible circuit board facing the cover plate and extending out of the edge of the array substrate and the edge of the array substrate. A line of glue is generally coated in a line shape, and the surface of the flexible circuit board, which extends out of the edge of the array substrate and faces the cover plate, can be firmly adhered to the edge of the array substrate so as to perform auxiliary fixing on the flexible circuit board. Of course, the above-mentioned step of bonding the flexible circuit board and the edge of the array substrate by using the wire adhesive is not only applicable to the flexible circuit board, but also applicable to other components of the same condition in the binding circuit, and refer to step S35 in fig. 8.
The embodiment of the present invention further provides a display device, please refer to fig. 5 and fig. 6, where the display device includes the display panel provided in the above embodiment; the back side of the display panel is provided with a backlight module 9.
The backlight module 9 is generally provided with a backlight source, such as a Light-emitting diode (LED) array, and an LED-FPC91 for controlling the LED array.
The display panel in the display device has the same advantages as the display panel in the above embodiments, and the description thereof is omitted.
The display device provided by the above embodiment may be a product or a component having a display function, such as a mobile phone, a tablet computer, a notebook computer, a display, a television, a digital photo frame, or a navigator.
The above description is only a specific implementation manner of the embodiments of the present invention, but the scope of the embodiments of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the embodiments of the present invention, and all the changes or substitutions should be covered within the scope of the embodiments of the present invention.
