Description

Technical Field

[0001] This application relates to the field of display technology, and more specifically to a display module and display device. Background Technology

[0002] Currently, high screen-to-body ratio OLED display panels are becoming the mainstream. For display panels, a high screen-to-body ratio means that the width of the outer bezel of the display area is further compressed, and the width of the bottom bezel is becoming narrower and narrower. Due to the limitations of wiring and packaging requirements, the touch traces of the touch layer need to be electrically connected to the metal traces of the driving layer through the touch transfer hole (TP transfer hole) in the bottom bezel area. As the size of the bottom bezel area is compressed, there is a problem of touch failure caused by the peeling of the touch traces of the touch layer from the metal traces of the driving layer.

[0020] In a preferred embodiment, an optical adhesive layer is stacked on the side of the first touch trace away from the substrate, and a cover plate is disposed on the side of the optical adhesive layer away from the substrate.

[0021] In a preferred embodiment, the minimum distance from the connecting hole to the boundary line of the bending area is between 10 and 20 μm;

[0022] Preferably, the connecting hole is square;

[0031] Based on the same inventive concept, this application proposes a display device that includes the aforementioned display panel.

[0032] Compared with the prior art, the display module of this application optimizes the structure of the connection hole located in the lower bezel area of ​​its touch layer. In the bent state, the connection hole is configured such that its slope (taper) is not parallel to the bending direction of the display panel (screen body). That is, the edge of the connection hole near the bending area (i.e., the plane where the sidewall of the connection hole is located) is not parallel to the boundary line of the bending area (also known as the PB line) (the included angle is greater than 10°). Compared with the current design where the edge of the TP connection hole near the bending area is parallel to the boundary line of the bending area near the display area, it is equivalent to rotating the connection hole by a certain angle, so that the bending direction of the connection hole and the display panel is not parallel. This helps to reduce stress concentration at the bezel / edge of the connection hole in the bent state, improve the influence of stress on the bezel of the connection hole under the bent structure, improve the peeling problem between the first touch trace and the first metal trace of the driving layer located in the non-display area, and thus improve / avoid the touch failure caused by this.

[0040] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings.

[0041] It should be noted that, unless otherwise defined, the technical or scientific terms used in the embodiments of this application should have the ordinary meaning understood by one of ordinary skill in the art to which this application pertains. The terms "first," "second," and similar terms used in the embodiments of this application do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed after the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are only used to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0042] With technological advancements and rising consumer aesthetic standards, there is an increasing demand for thinner and lighter smart devices with higher screen-to-body ratios. For display panels, a high screen-to-body ratio means that the width of the outer bezel of the display area is further compressed, and correspondingly, the width of the bottom bezel becomes narrower and narrower.

[0043] In practice, the bottom bezel area is sometimes shortened by using FIAA (Fanout In AA) technology and then bending it to the back of the display panel through a pad-bending process. However, this structure can lead to touch layer failure in curved screens (or screens with a certain curvature around the display area).

[0044] Further investigation by the applicant revealed that the curved screen's display panel has a certain curvature. In the lower bezel area, the touch trace layer of the touch layer is electrically connected (overlapped) to the metal of the driving layer via a connection hole (also known as a TP line replacement hole). The location of this connection hole is relatively close to the encapsulation layer (CVD). During CVD coating, the thickness at the connection hole increases due to the CVD shadow. Furthermore, the touch trace (TP M2) at the connection hole location is subjected to normal tensile stress. During subsequent reliability testing, the SiON at the shadow location absorbs water and expands, causing peeling between the touch trace and the array metal to begin at the TP line replacement hole location, leading to touch failure.

[0045] Based on this discovery, the applicant improved the touch traces and connection holes to improve the peeling problem between the touch traces and the array metal, that is, to avoid the problem of touch failure.

[0046] To this end, a display module is proposed, comprising a display area, a non-display area at least partially surrounding the display area, the non-display area including a lower border area having a bent area (which can subsequently be bent to the back of the display panel, the starting point of the bend being the boundary line of the bent area), and further comprising:

[0047] substrate;

[0048] A driving layer is disposed on a substrate, and the driving layer includes a first metal trace located in a non-display area;

[0049] A light-emitting layer is disposed on the side of the driving layer away from the substrate;

[0050] A touch layer is disposed on the side of the light-emitting layer away from the substrate. This touch layer includes a first touch trace layer, comprising a first touch trace located in a non-display area. The first touch trace is electrically connected to a first metal trace via a connecting hole, and the angle between the extension line of the edge of the connecting hole near the bending area and the boundary line of the bending area near the display area is greater than 10°. This reduces stress concentration at the edge / frame / edge of the connecting hole in a bent state, improves the impact of stress on the frame of the connecting hole under bent structures, and alleviates the peeling problem between the first touch trace and the first metal trace of the driving layer located in the non-display area.

[0051] The display module and display device proposed in this application will now be described with reference to the accompanying drawings.

[0052] like Figure 1 The image shown is the front view structure of a display module according to an embodiment of this application.

[0053] The display module includes a display area and a non-display area surrounding at least a portion of the display area. The non-display area includes a lower border region 130 with a bending region 131. The bending region 131 can be bent to the back of the display area in a subsequent process along a boundary line 131a (the boundary line 131a is the starting position of the bending of the bending region 131) on the side of the bending region closest to the display area.

[0054] Specifically, the display area includes a first display area 110 and a second display area 120 that at least partially surrounds the first display area 110, with the second display area 120 located between the first display area 110 and the non-display area. Preferably, in a subsequent process, the non-display area includes a lower border region 130 that bends along the boundary line 131a of the bending area near the display area to the back of the second display area 120 (or the back of both the second display area 120 and the first display area 110). The boundary line 131a is the starting position of the bend in the bending area 131.

[0055] The display module includes a four-curved screen. Taking the four-curved screen as an example, the central area of ​​the display module is flat (i.e., the first display area 110 is flat), and the boundary areas of the display body are curved (i.e., the second display area 120 (also called the curved display area) has a certain curvature). The surface of the substrate located in the first display area 110 is flat, and the surface of the substrate located in the second display area 120 is curved. In the thickness direction, the distance from the edge of the second display area (curved display area) 120 away from the first display area 110 is the distance H of the plane on which the flat back surface of the first display area 110 is located (see...). Figure 2 The distance should be greater than or equal to 0.3mm (to make the curvature of the curved display area deeper). For example, this distance can be any value of 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm or greater than 0.5mm.

[0056] The display module also includes,

[0057] The substrate is a flexible substrate, and its material can be selected from polyimide (PI), polyethylene naphthalate (PEN) or polyethylene terephthalate (PET), etc., or it can be a mixture of the above materials. Alternatively, the substrate can be a rigid substrate, and its material can be selected from glass.

[0058] A driving layer is disposed on the substrate. The driving layer includes a pixel driving circuit located in the display area and a first metal trace located in the non-display area. The pixel driving circuit may include multiple transistors (TFTs), capacitors, etc., and may be formed in various forms such as 2T1C (i.e., 2 transistors (TFTs) and 1 capacitor (C)), 3T1C, or 7T1C. The pixel driving circuit is electrically connected to the light-emitting unit to control the switching state and brightness of the light-emitting unit.

[0059] The light-emitting layer, stacked on the substrate-away side of the driving layer, includes multiple light-emitting units, each of which is electrically connected to a matching pixel driving circuit. The light-emitting layer may further include one or more of the following: a hole injection layer, a hole transport layer, an organic light-emitting layer, an electron transport layer, and an electron injection layer; for example, it may further include one or more of the following: a hole blocking layer and an electron blocking layer.

[0060] An encapsulation layer, which is stacked on the light-emitting layer, is used to prevent water and oxygen from entering. The encapsulation layer may include a first sub-encapsulation layer and a second sub-encapsulation layer, such that the first sub-encapsulation layer is made of an inorganic material and the second sub-encapsulation layer is made of an organic material.

[0061] The touch layer, which is stacked on the side of the encapsulation layer away from the light-emitting layer, is also called the TP film layer. It can be a self-capacitive TP film layer or a mutual-capacitive TP film layer. The TP film layer may include a second touch trace layer, an insulating layer, and a first touch trace layer. The second touch trace layer includes a plurality of first touch signal units located in the display area and second touch traces located in the non-display area.

[0062] The first touch trace layer includes a plurality of second touch signal units located in the display area and a first touch trace located in the non-display area. An insulating layer is used to isolate the second touch trace layer and the first touch trace layer. The insulating layer extends to the lower bezel area (preferably, it extends to the boundary line of the lower bezel area near the bend area (also called the PB line, padbending), and a connection hole is provided in the insulating layer in the lower bezel area, through which the first touch trace of the first touch trace layer is electrically connected / lapped to the first metal trace.

[0063] In one embodiment, see Figure 1 and combined Figure 3 and Figure 4 ,

[0064] Preferably, the first touch trace 171 extends to the lower frame region 130 and overlaps with the first metal trace 142 of the driving layer through the connection hole 161 of the insulating layer 160 (the first metal trace 142 is an M5 for LTPO type driving or an M4 for LTPS type driving). Preferably, the surface of the first touch trace 171 covering part of the insulating layer, the connection hole (also called the wire replacement hole) 161, and the sidewall 161a of the connection hole 161 are electrically connected to the first metal trace 142.

[0065] The first metal trace 142 is disposed on a planarization layer 141, which is disposed on a substrate 140. In one embodiment, a second metal trace (not shown) is also disposed between the planarization layer 141 and the substrate 140. The connection hole is square, with a side length between 2-50 μm (e.g., a side length of 10 μm), or rectangular, with a side length between 10-20 μm (e.g., a rectangular connection hole with a side length of 10*20 μm). A bending area is provided on the side of the connection hole away from the display area, and the distance from the connection hole 161 to the boundary line (also called PB line, pad bending) of the display area side near the bending area is between 10-20 μm. An optical adhesive (e.g., OC organic adhesive) layer 180 is stacked on the first touch trace 171. A cover plate may be disposed on the side of the optical adhesive layer 180 away from the first metal trace 142. In implementation, after the encapsulation layer is prepared, a second touch trace layer is set on the encapsulation layer and patterned to obtain the second touch trace and the second touch signal unit. Then, an insulating layer 160 is set on it, which extends to the vicinity of the bending area and a connection hole (exposing the first metal trace) is set (in the bending area). The first touch trace layer is deposited on the insulating layer 160 and patterned to obtain the first touch trace and the first touch signal unit. The first touch trace is connected to the first metal trace through the connection hole.

[0066] The connecting hole 161 is configured such that the angle α between the extension of its edge near the bending area (the plane on which the sidewall near the bending area is located) and the boundary line (also called the PB line) of the bending area near the display area is greater than 10°. This angle α can be the angle between the extension of the edge of the connecting hole 161 near the bending area before the bending area is bent and the boundary line of the bending area near the display area. Preferably, the included angle α is between 10° and 50° (e.g., 10°, 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°); more preferably, α is between 15° and 45° (e.g., 15°, 20°, 25°, 30°, 35°, 40°, 45°); and most preferably, in a planar state, the included angle α is between 20° and 40°. With this design, the connecting hole is effectively rotated by a certain angle (currently, the edges of the TP cable replacement hole and the connecting hole near the bending area are parallel to the boundary line of the bending area; taking a square connecting hole as an example, the four sides of the current TP cable replacement hole are either parallel (approximately parallel) to the boundary line of the bending area near the display area, or perpendicular (approximately perpendicular) to the boundary line of the bending area near the display area). The connection hole in this application is rotated at a certain angle so that when in a bent state, the connection hole is not parallel to the bending direction of the display panel (taking a square connection hole as an example, its four sides are not perpendicular or parallel to the boundary line of the bending area). This helps to reduce stress concentration at the edge of the connection hole in a bent state and improve the influence of stress on the edge of the connection hole under the bending structure. Since it is not parallel to the bending direction of the display module, it helps to reduce stress concentration at the edge of the connection hole during bending, improve the influence of stress on the edge of the connection hole under the bending structure, and improve the peeling problem between the first touch trace and the first metal trace of the driving layer located in the non-display area, thereby improving / avoiding the resulting touch failure. Preferably, in this way, the existing size of the connection hole can be maintained, so no additional mask or new process is required in the manufacturing process. Preferably, the boundary line of the bending area is parallel to the boundary line of the first display area 110 near the lower bezel area, or to the boundary line of the second display area 120.

[0067] In one embodiment, the first metal trace 142 has an overlap portion 142a facing a connection hole 161 (i.e., the connection hole is located at the overlap portion and communicates with it). The first touch trace 171 overlaps with the overlap portion 142a through the connection hole. The material of the overlap portion 142a can be the same as the material of the first metal trace 142. During fabrication, an insulating layer 160 covers the first metal trace 142, and then the connection hole 161 (located in the lower border area) is fabricated when the insulating layer 160 is imaged, exposing the first metal trace 142 through the connection hole 161.

[0068] In one embodiment, see Figure 5 and Figure 6The first touch trace 171 is electrically connected / lapped to the first metal trace 142 or to the corresponding lap portion 142a of the first metal trace 142 through two or more connection holes 161. Thus, when the first touch trace 171 of one of the connection holes 161 peels away from the first metal trace 142, the remaining portion (the isolation portion 162 between adjacent connection holes 161) can remain conductive, thereby ensuring normal touch function. In this structure, the isolation portion 162 between the connection holes can be used to prevent peeling between metals (i.e., peeling occurs between the first touch trace 171 and the first metal trace 142 or with the corresponding lap portion 142a, but the isolation portion 162 between the connection holes prevents peeling, thus preventing deterioration and indirectly improving reliability). In this embodiment, the insulating layer corresponding to the first metal trace has two or more connecting holes, the size of which can be the same as the size of a single connecting hole. In other embodiments, the size of the connecting hole can be smaller than the size of a single connecting hole (e.g., the side length of the connecting hole is 2*2 or 3*3 μm). Preferably, the sides of the multiple connecting holes near the bending area are parallel to each other.

[0069] In one embodiment, the TP film layer includes a substrate, a second touch wiring layer, an insulating layer, and a first touch wiring layer. The substrate is stacked on the side of the encapsulation layer away from the light-emitting layer, the second touch wiring layer is stacked on the substrate on the side away from the encapsulation layer, and an insulating layer is stacked on top of it. The first touch wiring layer is disposed on the side of the insulating layer away from the second touch wiring layer, and the side of the first touch wiring layer away from the insulating layer has optical adhesive. A cover plate is disposed on the side of the optical adhesive away from the first touch wiring layer. The substrate can be made of PI material, optical adhesive, CPI material, or PET material. During manufacturing, a layer of liquid optical adhesive can be first coated on the encapsulation layer, and then cured by UV irradiation or exposure to prepare the optical adhesive layer.

[0070] It should be noted that the display panel can also include other functional structures. For example, the display panel can also include an identification structure to provide fingerprint recognition functionality. For instance, the identification structure can be a touch panel or a touch layer. The touch panel can be bonded to the display panel, or the touch layer can be directly fabricated on the encapsulation layer of the display panel, which facilitates a thinner and lighter design for the display panel.
