Detailed Description
In order to make the technical solutions of the present invention better understood, the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
In the present invention, the two structures "in the same layer" means that they are formed of the same material layer and thus are in the same layer in a stacked relationship, but do not represent that they are equidistant from the substrate nor that they are completely identical in structure with other layers 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 steps of forming a material layer, coating a photoresist, exposing, developing, etching, stripping a photoresist, 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 in the various figures are denoted by like reference numerals. For purposes of clarity, the various features in the drawings are not necessarily drawn to scale. Moreover, certain well-known elements may not be shown in the figures.
In the following description, numerous specific details of the invention, such as structure, materials, dimensions, processing techniques and techniques of components, are set forth in order to provide a more 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, so that the display panel and the support frame are fixed.
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: the array substrate and the color film substrate 12 are arranged in a box-to-box mode. The display panel includes: the liquid crystal display panel comprises an array substrate and a 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, at least one side of the edge portion (first region) of the array substrate is not covered by the color filter substrate 12, that is, a fault is formed between the array substrate and the edge portion of the color filter substrate 12 in the first region. The first area may include one or more of a detection area or a signal line binding area (e.g., a PAD area) or the like to be configured to connect a screen detection device or a driving chip (IC) or a screen driving board or the like.
When the display panel is fixed with the support frame, the color film substrate 12 is farther away from the support frame relative to the array substrate. That is, the support frame main body is located on the non-display surface side of the display panel. Conventionally, an adhesive layer is usually provided in the peripheral edge region of the color filter substrate 12, and the edge region of the color filter substrate 12 and the edge region of the support frame are bonded and fixed. The adhesive layer is generally conductive, so that electrostatic charges on the upper surface of the display panel can be quickly introduced into the backplane and then conducted to the ground, and the electrostatic Discharge (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 includes a pixel unit for displaying, but also includes a touch unit for realizing touch identification. Specifically, referring to fig. 1, when a finger (corresponding to the ground) touches the TDDI module, the coupling capacitance of the touch unit changes, and the touch position of the user is determined by recognizing the capacitance change, so as to perform a corresponding response. In order to ensure the touch performance of the TDDI module, the touch unit is usually disposed in the display panel as close as possible to the outermost surface layer.
In the prior art, for the TDDI module, the conductive tape is disposed at the edge region of the display panel, which causes a serious problem in the touch recognition performance of the edge region of the TDDI module. Specifically, when the adhesive layer having a conductive property is attached to the periphery of the display panel, the difference value is lower, and thus the touch sensitivity is reduced, and the problem that the edge is not cut or scribed is caused.
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 respectively adhered and fixed to the first region of the array substrate and the supporting frame, and the first adhesive tape 21 is not adhered to the color filter substrate 12.
Referring to fig. 1, when the periphery of the display panel is attached with the conductive adhesive layer, which is equivalent to that the edge area of the TDDI module is grounded, when a finger touches the edge of the TDDI module, the change of the coupling capacitance is reduced, which is expressed as a lower difference value, thereby causing a reduction in touch sensitivity and a problem of breaking or not scribing the edge. In this embodiment, when the display module and the support frame are bonded and fixed by the bonding layer, the first adhesive tape 21 is only connected to the array substrate, but not connected to the color filter substrate 12, that is, the first adhesive tape 21 is connected to the support frame through the cross-sectional position areas of the color filter substrate 12 and 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 longer, so that the electric signal of the touch unit can be prevented from being affected.
Optionally, in some examples, the array substrate includes: a conductive part 11a disposed in the first region of the array substrate; the orthographic projection of the first tape 21 on the array substrate covers the orthographic projection of the conductive part 11a on the array substrate.
Wherein the first area may include one or more of a detection area or a signal line binding area (e.g., PAD area) or the like configured to connect to a screen detection device or a driving chip (IC) or a screen driving board or the like. That is, the conductive portion 11a of the display panel may be provided in this region to connect the internal circuit of the array substrate with an external driving chip, a driving board, and the like. The conductive part 11a includes at least one conductive element such as a signal trace or a line probing point. In addition, the conductive portion 11a serves as an integral part of the array substrate, which can be fabricated together with the pixel driving circuit in the array substrate in the fabrication process of the array substrate.
The orthographic projection of the conductive part 11a on the array substrate is positioned in the orthographic projection of the first tape 21 on the array substrate. Optionally, the conductive portion 11a is opposite to the first tape 21, and an orthographic projection area of the conductive portion 11a on the array substrate is smaller than an orthographic projection area of the first tape 21 on the array substrate, at this time, the first tape 21 can rapidly guide the electrostatic charges on the upper surface of the display panel into the backplane, and then the electrostatic charges are conducted into the ground, so that the ESD capability of the display panel is effectively improved. Meanwhile, the first adhesive tape 21 is not disposed on the color film substrate 12, so that the signal of the touch unit can be prevented from being affected. The first tape 21 is grounded, and can provide EMI protection for the conductive portion 11a located below (on the non-display side). It should be noted that an insulating layer should be disposed between the first tape 21 and the conductive part 11a to effectively insulate the conductive part 11a from the first 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 bonds and fixes a portion of the color film substrate 12 corresponding to the second edge region to the support frame. In the display panel, in the edge region of a part of the side, the array substrate is flush with the color filter substrate 12, that is, the edge of the array substrate on the side is completely covered by the color filter substrate 12. In order to secure the display panel and the rubber frame, the display panel and the rubber frame are preferably bonded and fixed at each side position of the display panel. Since the color film substrate 12 is flush with the array substrate, the adhesive layer needs to be bonded and fixed with the adhesive frame through the color film substrate 12. Specifically, referring to 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 comprising an insulating material; part of the edge area is adhesively secured to the support frame by means of a second adhesive tape 22. It can be understood that the orthographic projection of the bonding 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, when the adhesive layer is still closer to the edge of the display area. In this embodiment, the adhesive tape is an insulating adhesive tape, so that an electrical signal is blocked, and the electrical signal in the working process of the display panel is prevented from being affected. Specifically, for example, the coupling capacitance of the touch unit in the touch display panel can be prevented from being affected, so that the touch recognition sensitivity and accuracy of the touch display panel can be improved.
In some examples, the material of the adhesive layer includes a light blocking material. The adhesive layer has light shielding performance, so that light leakage of the display module adhered through the adhesive layer from the side can be prevented. Optionally, the substrate in the tape is a light-shielding substrate, that is, the substrate is made of a material having light-proof property or light transmittance of less than or equal to 10%, such as black polyimide. When the adhesive layer is made of a conductive material, the material of the adhesive layer may include a light-shielding conductive adhesive layer, that is, the conductive adhesive layer is made of a conductive adhesive with light-proof property or light transmittance less than or equal to 10%, for example, a 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 to the first surface; the display panel is provided with a first surface close to the support 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 is provided with an inward sunken area for accommodating the display panel, so that the display panel can be embedded in the inward sunken area. When the display panel is embedded in the supporting frame, the second surface (light-emitting 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 is understood that the projection of the adhesive layer on 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 tape 21 includes a first portion 21a and a second portion 21b, the first portion 21a being adhesively secured to a first area of the display panel; the second part 21b is fixedly bonded with the support frame; the length of the first part in the extending direction parallel to the corresponding side edge of the first area is larger than the length of the second part in the extending direction parallel to the corresponding side edge of the first area. The first region is a region not covered by the color filter 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 is overlapped with the orthographic projection of the first area on the substrate, and the first part extends along the extending direction of the corresponding side edge; the second part covers partial area of the support frame, and the extending direction of the second part is consistent with that 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 filter substrate 12 at the position of the fault with the support frame. 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 inner line of the plane where the first area is located is in the display module. That is, the first tape 21 has a climbing slope when adhering the array substrate and the frame. In this embodiment, the extension length of the first portion and the extension length of the second portion of the first tape 21 are designed, so that a step difference exists between two portions of the two edge ends of the first tape 21, which are bonded to the array substrate and the support frame, and the bonding area where the first portion protrudes from the second portion can ensure that the first tape 21 is bonded and fixed to the array substrate by using the shortening difference, thereby preventing the second portion from pulling the first portion after climbing a slope, which causes the two ends of the first portion to tilt.
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 the second edge region is not covered; 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 second tape 22 is used to adhere and fix the display panel to the frame, and the second tape 22 is adhered to the area of the color filter substrate 12 not covered by the polarizer 13. Through the above limitation on 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 away from the color film substrate 12, so that a glass cover plate and other accessories can be smoothly mounted on the polarizer 13.
In some examples, the display module further comprises a backlight module. The backlight module is configured to provide backlight to the display panel, and a light emitting area of the backlight module is generally disposed corresponding to a 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 supporting frame and the backlight module are mutually independent, and the backlight module is positioned on one side of the supporting frame, which is deviated from the light-emitting surface of the display panel.
In some examples, the backlight module includes a base, and a backlight source, a light guide plate, and an optical film set stacked on the base. 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 board, a flexible circuit board electrically connected with the display panel and connectors respectively and electrically connected with the screen driving board and the flexible circuit board.
On the other hand, the present embodiment provides a display device, including any one of the above display modules.
The display device has the same beneficial effects as the display module in some embodiments. Since the foregoing embodiments have described the structure and the beneficial effects of the display module in detail, the details are not repeated herein.
Specifically, in some examples, the display device may be any product or component having a display function, such as a liquid crystal display panel, a vehicle-mounted display device, electronic paper, a mobile phone, a tablet computer, a television, a display, a notebook computer, a digital photo frame, and a navigator.
