Detailed Description
The present invention will be described in further detail below with reference to the drawings and detailed description for the purpose of better understanding of the technical solution of the present invention to those skilled in the art.
In the present invention, the term "co-layer arrangement" means that both are formed from the same material layer, so that they are in the same layer in a stacked relationship, but do not represent that they are equidistant from the substrate, nor that they are exactly the same as the other layer structures between the substrate.
In the present invention, the "patterning process" refers to a step of forming a structure having a specific pattern, which may be a photolithography process including one or more of the steps of forming a material layer, coating photoresist, exposing, developing, etching, photoresist stripping, and the like; of course, the "patterning process" may also be an imprinting process, an inkjet printing process, or other processes.
The invention will be described in more detail below with reference to the accompanying drawings. Like elements are denoted by like reference numerals throughout the various figures. For clarity, the various features of the drawings are not drawn to scale. Furthermore, some well-known portions may not be shown in the drawings.
Numerous specific details of the invention, such as construction, materials, dimensions, processing techniques and technologies, may be set forth in the following description in order to provide a thorough understanding of the invention. However, as will be understood by those skilled in the art, the present invention may be practiced without these specific details.
In one aspect, the present embodiment provides a display module. Referring to fig. 1 to 4, the display module includes: display panel, support frame and adhesive layer (Cell Tape). The bonding layer is configured to bond the display panel to the support frame to fix the display panel to the support frame.
The display panel generally has a display area AA and a non-display area (peripheral area) located at the periphery of the display area. Display surface) the display panel includes: an array substrate and a color film substrate 12 arranged in a box. The display panel includes: the array substrate and the color film substrate 12 arranged on the array substrate. When the display panel is a liquid crystal display panel, a liquid crystal layer is disposed between the array substrate and the color film substrate 12. In addition, an edge portion (first area) of at least one side of the array substrate is not covered by the color film substrate 12, that is, a fault exists between the array substrate and the edge portion of the color film substrate 12 in the first area. The first region may include one or more of a detection region or a signal line binding region (e.g., PAD region), etc., configured to connect to a screen detection device or a driver chip (IC), or a screen driver board, etc.
When the display panel is fixed to the support frame, the color film substrate 12 is farther away from the support frame than the array substrate. That is, the supporting frame body is located on the non-display surface side of the display panel. In the prior art, an adhesive layer is generally disposed on the peripheral edge region of the color film substrate 12, and the edge region of the color film substrate 12 is adhered and fixed to the edge region of the supporting frame. The adhesive layer has conductivity, so that the electrostatic charge on the upper surface of the display panel can be quickly led into the back plate and then conducted to the ground, and the electrostatic discharge (Electro Static Discharge, abbreviated as ESD) resistance of the display panel is effectively improved.
The display module provided by the embodiment is particularly suitable for a touch display module (TDDI module). In the touch display module, the display panel not only comprises a pixel unit for display, but also comprises a touch unit for realizing touch identification. Specifically, referring to fig. 1, when a finger (equivalent to ground) touches the TDDI module, the coupling capacitance of the touch unit changes, and the user touch position is confirmed by identifying the capacitance change, so as to perform a corresponding reaction action. In order to ensure the touch performance of the TDDI module, the touch unit is generally disposed at a position in the display panel that is as close to the outermost surface layer as possible.
In the prior art, for the TDDI module, the placement of the conductive tape on the edge area of the display panel causes serious problems in touch recognition performance of the edge area of the TDDI module. Specifically, when the conductive adhesive layer is attached to the periphery of the display panel, the difference value is lower, so that the touch sensitivity is reduced, and the problems of broken lines, insufficient scribing, and the like occur.
Based on the above technical problem, in the display module provided in this embodiment, the adhesive layer includes the first adhesive tape 21, the first adhesive tape 21 is adhered and fixed to the first area of the array substrate and the supporting frame, and the first adhesive tape 21 is not adhered to the color film substrate 12.
Referring to fig. 1, when an adhesive layer with conductive properties is attached to the periphery of a display panel, the edge area of the TDDI module is grounded, and when a finger touches the edge of the TDDI module, the change of coupling capacitance is reduced, which is represented by a lower difference value, so that the touch sensitivity is reduced, and the problems of disconnection or scribing cannot reach the edge are caused. In this embodiment, when the display module and the support frame are adhered and fixed by the adhesive layer, the first adhesive tape 21 is only connected with the array substrate, but not with the color film substrate 12, that is, the first adhesive tape 21 is connected with the support frame through the color film substrate 12 and the fault position region of the array substrate. It can be understood that in this arrangement, the distance between the adhesive layer and the touch unit of the display panel becomes long, so that the influence on the electrical signal of the touch unit can be avoided.
Optionally, in some examples, the array substrate includes: a conductive portion 11a provided in a first region of the array substrate; the orthographic projection of the first adhesive tape 21 on the array substrate covers the orthographic projection of the conductive portion 11a on the array substrate.
Wherein the first region may include one or more of a detection region or a signal line binding region (e.g., PAD region) or the like to be configured to connect to a screen detection device or a drive chip (IC) or a screen drive board or the like. That is, the conductive portion 11a of the display panel may be provided in this region, and the internal circuit of the array substrate may be connected to an external driving chip, a driving board, or the like. The conductive portion 11a is at least one conductive element including a signal trace or a trace detection point. In addition, the conductive portion 11a is a component of the array substrate, and can be manufactured together with the pixel driving circuit in the array substrate during the manufacturing process of the array substrate.
The orthographic projection of the conductive portion 11a on the array substrate is located within the orthographic projection of the first adhesive tape 21 on the array substrate. Optionally, the conductive portion 11a is opposite to the first adhesive tape 21, and the orthographic projection area of the conductive portion 11a on the array substrate is smaller than the orthographic projection area of the first adhesive tape 21 on the array substrate, at this time, the first adhesive tape 21 can rapidly guide the electrostatic charges on the upper surface of the display panel into the back plate, so as to be conducted into the ground, thereby effectively improving the ESD capability of the display panel. Meanwhile, the first adhesive tape 21 is not arranged on the color film substrate 12, so that the influence on the signal of the touch unit can be avoided. Also, the first tape 21 is grounded, so that it can provide EMI protection to the conductive portion 11a located therebelow (non-display side). It should be noted that an insulating layer should be disposed between the first adhesive tape 21 and the conductive portion 11a to effectively insulate the conductive portion 11a from the first adhesive tape 21.
In some examples, the array substrate includes a first edge region including the first region and a second edge region covered by the color film substrate 12; the adhesive layer further includes a second adhesive tape 22, and the second adhesive tape 22 adheres and fixes the portion of the color film substrate 12 corresponding to the second edge area to the support frame. In the display panel, in the edge region of the partial side, the array substrate is flush with the color film substrate 12, i.e., the edge of the array substrate on the side is completely covered by the color film substrate 12. In order to ensure the fixation of the display panel and the glue frame, the display panel and the glue frame are preferably adhered and fixed at the positions of each side edge of the display panel. The color film substrate 12 is flush with the array substrate, and the adhesive layer is required to be adhered and fixed with the adhesive frame through the color film substrate 12. Specifically, as shown in fig. 2 to 4, a partial region of the adhesive layer is adhered to the color filter substrate 12, and a partial region is adhered to the support frame.
In some examples, the adhesive layer further includes a second tape 22, the material of the second tape 22 including an insulating material; part of the edge area is adhesively secured to the support frame by means of a second adhesive tape 22. It is understood that the orthographic projection of the adhesive layer on the display module should fall into the non-display area of the display module to avoid shielding the normal display of the display module. Even so, the adhesive layer is still closer to the edge of the display area. In this embodiment, the portion of the adhesive tape is set as an insulating adhesive tape, so as to isolate the electrical signal and avoid the influence on the electrical signal in the working process of the display panel. Specifically, for example, the influence on the coupling capacitance of the touch unit in the touch display panel can be avoided, so that the touch recognition sensitivity and accuracy of the touch display panel are improved.
In some examples, the material of the adhesive layer includes a light shielding material. The adhesive layer has a light shielding performance, so that light leakage from the side of the display module adhered by the adhesive layer can be prevented. Optionally, the substrate in the adhesive tape is a light-shielding substrate, that is, the substrate is made of a material with light-tightness or light-transmittance less than or equal to 10%, for example, black polyimide. When the adhesive layer is made of conductive material, the material may include a light-shielding conductive adhesive layer, that is, the conductive adhesive layer is made of conductive adhesive with light-tightness or light-transmittance less than or equal to 10%, for example, black conductive adhesive.
In some examples, the display panel is embedded in a support frame, the support frame having a first surface facing away from the display panel and a second surface opposite the first surface; the display panel is provided with a first surface close to the supporting frame and a second surface opposite to the first surface; the second surface of the display panel and the second surface of the supporting frame are in the same plane. The support frame has an inward sinking region for accommodating the display panel so that the display panel can be embedded therein. When the display panel is embedded in the supporting frame, the second surface (light emergent surface) of the display panel and the second surface of the supporting frame are located in the same plane. The adhesive layer may directly cover the second surface of the support frame and the second surface of the display panel, thereby adhesively fixing the display panel to the support frame. It will be appreciated that the projection of the adhesive layer onto the display panel should fall into the non-display area of the display panel to avoid affecting the normal display of the display panel.
In some examples, the first adhesive tape 21 includes a first portion 21a and a second portion 21b, the first portion 21a being adhesively secured to the first region of the display panel; the second part 21b is fixedly adhered to the support frame; the length of the first portion in the extending direction parallel to the corresponding side of the first region is longer than the length of the second portion in the extending direction parallel to the corresponding side of the first region. The first area is an area not covered by the color film substrate 12. That is, in the present embodiment, the first tape 21 passes through a first portion adhered to the array substrate and a second portion adhered to the support frame. Wherein, the orthographic projection of the first part of the first adhesive tape 21 on the array substrate overlaps with the orthographic projection of the first area on the substrate, and the first part extends along the corresponding side extending direction; the second part covers a part of the area of the supporting frame, and the second part is consistent with the extending direction of the first part. The first portion has an extension length greater than an extension length of the second portion. It can be understood that the first adhesive tape 21 adheres and fixes the array substrate and the color film substrate 12 to the support frame at the fault position. The upper surface of the supporting frame and the upper surface of the color film substrate 12 are in the same plane, so that the first area is in the plane of the display module. That is, the first tape 21 has a slope when bonding the array substrate and the frame. In this embodiment, by designing the extension lengths of the first portion and the second portion of the first adhesive tape 21, there is a level difference between two portions of the two edge ends of the first adhesive tape 21, which are bonded to the array substrate and the support frame, and by using the change of the level difference, the bonding area of the first portion protruding from the second portion can ensure that the first adhesive tape 21 is bonded to the array substrate, so that the second portion is prevented from pulling the first portion after climbing, and the two ends of the first portion are prevented from tilting.
Optionally, in some examples, the display module further includes: the polarizer 13 is arranged on one side of the color film substrate 12, which is far away from the array substrate, and the orthographic projection of the polarizer 13 on the array substrate is smaller than that of the color film substrate 12 on the array substrate and does not cover the second edge area; the thickness of the second adhesive tape 22 is less than or equal to the thickness of the polarizer 13. Referring to fig. 3 and 4, in the present embodiment, the display panel is adhered and fixed to the frame by using the second adhesive tape 22, and the second adhesive tape 22 is adhered to the area of the color film substrate 12 not covered by the polarizer 13. By limiting the relative thickness dimensions of the second adhesive tape 22 and the polarizer 13, the outer surface of the second adhesive tape 22 is not higher than the surface of the polarizer 13 facing away from the color film substrate 12, so that other accessories such as a glass cover plate and the like can be mounted on the polarizer 13 smoothly.
In some examples, the display module further includes a backlight module. The backlight module is configured to provide backlight for the display panel, and the light emitting area of the backlight module is generally arranged corresponding to the display area of the display panel. The structure of the backlight module can be selected and set according to actual requirements. In some examples, the support frame may be part of a backlight module. Or the support frame and the backlight module are mutually independent, and the backlight module is positioned at one side of the support frame away from the light emitting surface of the display panel.
In some examples, the backlight module includes a chassis, and a backlight, a light guide plate, and an optical film set stacked on the chassis. Wherein, optionally, the optical film group comprises at least one layer of functional film, such as a diffusion sheet and a brightness enhancement sheet which are arranged in a stacked manner.
In some examples, the display module further comprises: the display panel comprises a screen driving plate, a flexible circuit board electrically connected with the display panel and a connector electrically connected with the screen driving plate and the flexible circuit board respectively.
On the other hand, the embodiment provides a display device, which comprises any one of the display modules.
The display device has the same beneficial effects as the display module in the embodiments. Since the foregoing embodiments have already described the structure and the beneficial effects of the display module, they are not described in detail herein.
