Description

Technical Field

[0001] The present application relates to the technical field of display panels, and in particular to a touch control module, a foldable display module, and a display device. Background Art

[0002] Currently, in the technical field of OLED (Organic Light-Emitting Diode), due to the integration and fabrication of touch sensors on the encapsulation layer of the OLED screen body, that is, the TOE (Touch on cell) technology is thinner and lighter than the traditional external touch panel lamination, it has achieved great development and application.

[0003] However, the existing TOE technology usually fabricates color filters on the encapsulation layer of the OLED screen body, and makes their orthographic projections respectively fill the light-emitting regions of the red, green, and blue sub-pixels of the OLED screen body, and fills the black matrix in the non-light-emitting regions by orthographic projection to absorb incident ambient light and reduce the OLED reflectivity. That is, the traditional TOE and COE (Color filter On Encapsulation) structures are respectively independent structural designs and manufacturing processes, so that the COE patterning scheme is usually more complex and the process risks are also more. Summary of the Invention

[0004] The main technical problem to be solved by the present application is to provide a touch control module, a foldable display module, and a display device to solve the problems that the COE patterning scheme in the display panel of the existing technology is usually more complex and the process risks are more.

The third insulating dielectric layer covers the second insulating dielectric layer, and the second electrode layer is disposed on the third insulating dielectric layer and the bottom of the groove body.

[0010] Among them, the third light-emitting filling layer and the third insulating dielectric layer are at least partially connected.

[0011] Among them, the color filter layer further includes a black matrix. The black matrix fills the gap between the first filling layer, the second light filtering layer, and the third light filtering layer, and covers the second electrode layer. At the same time, the black matrix also covers the insulating dielectric layer on the side away from the first electrode layer.

[0012] Among them, the width of the groove body in the set direction is equal to or less than the width of the first insulating dielectric layer in the set direction; wherein, the set direction is the extending direction of the first insulating dielectric layer.

[0016] To solve the above technical problems, yet another technical solution adopted by this application is: to provide a display device, among which, the display device includes a housing and a display module that are connected, and the display module is the display module described above.

The first insulating dielectric layer covers the first electrode layer, and a groove exposing a part of the first electrode layer is formed on the first insulating dielectric layer. The second electrode layer is further disposed on the bottom and the groove wall of the first insulating dielectric layer and the groove to connect the first electrode layer. Thus, by integrating the first electrode layer and the second electrode layer into the color filter layer and achieving electrical connection through the groove on the first insulating dielectric layer, the conduction difficulty between the touch electrodes can be effectively reduced, and its dielectric and impedance performance, as well as the manufacturing yield, are improved. This also enhances the touch performance of the touch module and reduces the risk of process defects, providing a clear solution for mass production of the process. BRIEF DESCRIPTION OF THE DRAWINGS

Those skilled in the art will explicitly and implicitly understand that the embodiments described herein may be combined with other embodiments.

[0030] Next, the present application will be described in detail in conjunction with the accompanying drawings and embodiments.

[0031] Please refer to Figures 1-3 , wherein, Figure 1 It is a schematic structural diagram of an embodiment of the touch control module of the present application, Figure 2 is Figure 1 a cross-sectional top view of a first electrode layer, a color filter layer, and a second electrode layer in the touch control module inFigure 3 Yes Figure 2 It is a detailed structural schematic diagram of a first light - filtering layer in a color - film layer. In this embodiment, the touch control module 10 includes: an insulating buffer layer 11, a first electrode layer 12, a color - film layer 13, and a second electrode layer 14.

[0032] Among them, the touch control module 10 is specifically used to cover the display screen body layer 20, provide protection for the display screen body layer 20, and flatten the display screen body layer 20, so that the display screen body layer 20 has the functions of touch control and light filtering.

[0033] And the display screen body layer 20 specifically includes a thin - film transistor layer 21, a light - emitting layer 22, and a packaging layer 23 which are stacked in sequence. And the light - emitting layer 22 further includes spaced - apart light - emitting units, for example, a red light - emitting unit 221, a green light - emitting unit 222, and a blue light - emitting unit 223, or RGBW (Red Green Blue White) light - emitting units, to be used for realizing the display function of corresponding products.

[0034] Specifically, the insulating buffer layer 11 is correspondingly arranged on the display screen body layer 20 to protect the display screen body layer 20 and serve as the base of the touch control module 10, so as to facilitate the realization of color - film light - filtering and touch - control functions.

[0035] Further, the first electrode layer 12 is correspondingly arranged on the insulating buffer layer 11, and the color - film layer 13 further includes a light - filtering layer. The light - filtering layer corresponds to the light - emitting units and can be one or more, which can be specifically set according to specific situations.

[0036] In this embodiment, taking three light - emitting units of a red light - emitting unit 221, a green light - emitting unit 222, and a blue light - emitting unit 223 as an example, the light - filtering layer includes a first light - filtering layer 131, a second light - filtering layer 132, and a third light - filtering layer 133. And the first light - filtering layer 131, the second light - filtering layer 132, and the third light - filtering layer 133 are correspondingly arranged at intervals on the insulating buffer layer 11 and are respectively arranged corresponding to the light - emitting layers 22 of the same color in the display screen body layer 20.

[0037] It should be noted that there is a gap between the first electrode layer 12 and each light - filtering layer in this embodiment.

[0038] Among them, the first light - filtering layer 131 further includes a first filling layer 1311 and a first insulating dielectric layer 1312. And the first filling layer 1311 and the first insulating dielectric layer 1312 are specifically in the same process flow and made of the same material, so as to effectively reduce the process complexity of the touch control module 10.

[0039] It should be noted that any one of the first light filtering layer 131, the second light filtering layer 132, and the third light filtering layer 133 in the color film layer 13 is a red light filtering layer, another is a green light filtering layer, and yet another is a blue light filtering layer. That is, the first light filtering layer 131, the second light filtering layer 132, and the third light filtering layer 133 are not limited to a combination arranged in any order among the red light filtering layer, the green light filtering layer, and the blue light filtering layer, nor is the specific process manufacturing order limited. In addition, when the light filtering layer includes a filling layer and an insulating dielectric layer, the filling layer corresponds to the corresponding light emitting unit, that is, the orthographic projection of the filling layer on the light emitting layer 22 covers the corresponding light emitting unit. For example, the first light filtering layer 131 is a red light filtering layer, the first light filtering layer 131 includes a first filling layer 1311 and a first insulating dielectric layer 1312, and the orthographic projection of the first filling layer 1311 on the light emitting layer 22 covers the corresponding red light emitting unit. When the light filtering layer is only a simple light filtering layer, the orthographic projection of the light filtering layer on the light emitting layer 22 covers the corresponding light emitting unit.

[0040] Further, the first insulating dielectric layer 1312 is specifically covered on the first electrode layer 12 to cooperate with the insulating buffer layer 11 to wrap the first electrode layer 12 for protecting the first electrode layer 12 to prevent over-etching or oxidation.

[0041] And a groove 1313 exposing a part of the first electrode layer 12 is also correspondingly formed on the first insulating dielectric layer 1312, and the second electrode layer 14 is specifically arranged on the bottom and the groove wall of the first insulating dielectric layer 1312 and the groove 1313, that is, a part of the second electrode layer 14 is filled in the groove 1313 to correspondingly connect with the first electrode layer 12 to facilitate the transmission of the touch signal. In this embodiment, the circuit layout of the touch sensor is realized through the insulating function of the first light filtering layer 131, without additionally providing an independently arranged insulating layer to isolate between the two electrodes, and at the same time, the integration of the touch function and the color film light filtering function is effectively realized, the thickness of the entire film layer is effectively reduced, and thus it is beneficial to the thinning design of related products.

[0042] In the above solution, by integrating the first electrode layer 12 and the second electrode layer 14 into the color film layer 13 and realizing the conductive connection through the groove 1313 on the first insulating dielectric layer 1312, the conduction difficulty between the touch electrodes is effectively reduced, and its dielectric and impedance performance, as well as the manufacturing yield, are improved, and thus the touch performance of the touch module 10 is improved and the risk of process defects is reduced. And by integrating the touch function and the color film light filtering function, a clear solution is provided for mass production of the process.

[0043] In one embodiment, the color filter layer 13 further includes a black matrix 134. The black matrix 134 fills the gap between the first color filter layer 131, the second color filter layer 132, and the third color filter layer 133. That is, a part of the black matrix 134 in this embodiment is disposed on the insulating buffer layer 11. At the same time, the black matrix 134 covers the second electrode layer 14 to provide insulation protection for the second electrode layer 14. In addition, the black matrix 134 also covers the insulating dielectric layer on the side away from the first electrode layer 12. That is, the black matrix 134 in this embodiment also covers the first insulating dielectric layer 1312, thereby effectively preventing light from emitting from the first insulating dielectric layer 1312 to ensure the display effect.

[0044] In one embodiment, one of the first electrode layer 12 and the second electrode layer 14 is specifically a bridge point electrode, and the other is a touch electrode, so as to realize the transmission of touch signals when the bridge point electrode and the touch electrode are connected. Specifically, the bridge point electrode may be covered by the first insulating dielectric layer 1312, or the touch electrode may be covered by the first insulating dielectric layer 1312. That is, the spatial positions of the bridge point electrode and the touch electrode can be interchanged in the actual implementation of the solution.

[0045] Furthermore, the width of the first insulating dielectric layer 1312 in the set direction is greater than the width of the first electrode layer 12 in the set direction, so as to cover the first electrode layer 12 to protect the electrode traces and prevent over-etching or oxidation. Wherein, the set direction is specifically the extending direction of the first insulating dielectric layer 1312.

[0046] In one embodiment, the touch module 10 is specifically disposed corresponding to the AA (Active Area, display area) area of the display screen layer 20.

[0047] In one embodiment, as Figure 3 shown, the width of the groove 1313 formed corresponding to the first insulating dielectric layer 1312 in the set direction may specifically be less than the width of the first insulating dielectric layer 1312 in the set direction. That is, the groove 1313 is specifically a through hole on the first insulating dielectric layer 1312 for realizing the electrical connection between the first electrode layer 12 and the second electrode layer 14.

[0048] Wherein, the set direction is specifically the extending direction of the first insulating dielectric layer 1312.

[0049] Please continue to refer to Figure 4 , Figure 4 which Figure 2 is a detailed structural schematic diagram of another embodiment of the first color filter layer in the color filter layer in

[0050] In this embodiment, the width of the groove 1313 formed corresponding to the first insulating dielectric layer 1312 in a set direction may specifically be equal to the width of the first insulating dielectric layer 1312 in the set direction, that is, the groove 1313 may specifically divide the first insulating dielectric layer 1312 into two segments to be used for realizing the electrical connection between the first electrode layer 12 and the second electrode layer 14.

[0051] In addition, as Figure 4 shown, the first filling layer 1311 and the first insulating dielectric layer 1312 in this embodiment are at least partially connected, and only need to ensure that they are in the same process flow and made of the same material.

[0052] Please continue to refer to Figure 5 and Figure 6 , where Figure 5 is Figure 1 a cross-sectional top view of another embodiment of the first electrode layer, color filter layer, and second electrode layer in the touch control module in Figure 6 is Figure 5 a schematic cross-sectional view of the first electrode layer, color filter layer, and second electrode layer at the groove in Figure 2 . The difference between the touch control module in this embodiment and Figure 2 an embodiment of the touch control module provided in this application in

[0053] is that the second light filtering layer 132 in the color filter layer 13 further includes a second filling layer 1321 and a second insulating dielectric layer 1322.

[0054] It can be understood that the specific layers covering the first electrode layer 12 may also be two layers. Specifically, the first insulating dielectric layer 1312 covers the first electrode layer 12, and the second insulating dielectric layer 1322 further covers the first insulating dielectric layer 1312, and at least part of the groove 1313 on the first insulating dielectric layer 1312 still exposes the first electrode layer 12. After part of the second electrode layer 14 is filled in the groove 1313, the second electrode layer 14 can be connected to the first electrode layer 12. And by covering the first electrode layer 12, the first electrode layer 12 can be effectively protected to prevent over-etching or oxidation.

[0055] It should be noted that, in this embodiment, the black matrix 134 not only fills the gaps between the first light filtering layer 131, the second light filtering layer 132, and the third light filtering layer 133, and covers the second electrode layer 14, but also covers the insulating dielectric layer on the side away from the first electrode layer 12, that is, the black matrix 134 in this embodiment also covers the second insulating dielectric layer 1322, thereby effectively preventing light from emitting from the first insulating dielectric layer 1312 and the second insulating dielectric layer 1322 to ensure the display effect.

[0056] Optionally, the width of the second insulating dielectric layer 1322 in the set direction is greater than the width of the first electrode layer 12 in the set direction to be able to wrap the first electrode layer 12.

[0057] Preferably, the width of the first insulating dielectric layer 1312 in the set direction is greater than the width of the first electrode layer 12 in the set direction, and the width of the second insulating dielectric layer 1322 in the set direction is greater than the width of the first insulating dielectric layer 1312 in the set direction.

[0058] In another embodiment, the second insulating dielectric layer 1322 may specifically also cover the first insulating dielectric layer 1312, and specifically, the second electrode layer 14 is disposed on the bottom and the side walls of the second insulating dielectric layer 1322 and the groove 1313 to be connected to the first electrode layer 12.

[0059] Similarly, the second filling layer 1321 and the second insulating dielectric layer 1322 in this embodiment are at least partially connected, and it is only necessary to ensure that they are in the same process flow and made of the same material.

[0060] Furthermore, in one embodiment, the third light filtering layer 133 in the color film layer 13 further includes a third filling layer (not shown in the figure) and a third insulating dielectric layer (not shown in the figure), and the third insulating dielectric layer specifically covers the second insulating dielectric layer 1322, and the second electrode layer 14 is correspondingly disposed on the bottom of the third insulating dielectric layer and the groove 1313 to be connected to the first electrode layer 12.

[0061] In this embodiment, in addition to filling the gaps between the first light filtering layer 131, the second light filtering layer 132, and the third light filtering layer 133, and covering the second electrode layer 14, the black matrix 134 also covers the insulating dielectric layer on the side away from the first electrode layer 12, that is, the black matrix 134 in this embodiment also covers the third insulating dielectric layer, thereby effectively preventing light from emitting from the first insulating dielectric layer 1312, the second insulating dielectric layer 1322, and the third insulating dielectric layer to ensure the display effect.

[0062] Optionally, the width of the third insulating dielectric layer in the set direction is greater than the width of the first electrode layer 12 in the set direction, so as to be able to wrap the first electrode layer 12.

[0063] Preferably, the width of the first insulating dielectric layer 1312 in the set direction is greater than the width of the first electrode layer 12 in the set direction, the width of the second insulating dielectric layer 1322 in the set direction is greater than the width of the first insulating dielectric layer 1312 in the set direction, and the width of the third insulating dielectric layer in the set direction is greater than the width of the second insulating dielectric layer 1322 in the set direction, so as to wrap the previous layer close to the insulating buffer layer 11 in sequence.

[0064] It should be noted that when etching to obtain the second insulating dielectric layer 1322, if the second insulating dielectric layer 1322 does not wrap the first insulating dielectric layer 1312, the first insulating dielectric layer 1312 will be etched again repeatedly, thus bringing the risk of Undercut (side etching) to the edge of the first insulating dielectric layer 1312; similarly, if the third insulating dielectric layer also does not wrap the second insulating dielectric layer 1322, there is also a risk of side etching at the edges of the first insulating dielectric layer 1312 and the second insulating dielectric layer 1322 during the process of etching to obtain the third insulating dielectric layer.

[0065] By wrapping the third insulating dielectric layer around the second insulating dielectric layer 1322 and wrapping the second insulating dielectric layer 1322 around the first insulating dielectric layer 1312, it is possible to effectively avoid the risk of side etching caused by repeatedly etching the inner insulating dielectric layer during the process of patterning the outer insulating dielectric layer.

[0066] And by wrapping the third insulating dielectric layer around the second insulating dielectric layer 1322 and wrapping the second insulating dielectric layer 1322 around the first insulating dielectric layer 1312, it is also possible to effectively prevent the first insulating dielectric layer 1312, the second insulating dielectric layer 1322, and the third insulating dielectric layer from all deviating from the insulating buffer layer 11, that is, the part facing the display direction of the finally manufactured display panel is exposed. During the image display process of the display panel, it is possible to effectively avoid the risk of color mixing due to the reflection of the first insulating dielectric layer 1312, the second insulating dielectric layer 1322, and the third insulating dielectric layer.

[0067] Similarly, at least part of the third light-emitting filling layer and the third insulating dielectric layer in this embodiment are connected. It only needs to ensure that they are in the same process flow and made of the same material. In one embodiment, the touch module 10 further includes a protective layer 15, and the protective layer 15 is correspondingly arranged on the first light-filtering layer 131, the second light-filtering layer 132, the third light-filtering layer 133, and the black matrix 134 to protect them.

[0068] The present application also provides a display device. Please refer to Figure 7 , Figure 7 which is a schematic structural diagram of an embodiment of the display module of the present application. Among them, the display module 30 specifically includes: a support layer 31, a display screen layer 32, a touch control module 33, and a cover plate 35 that are sequentially stacked.

[0069] Among them, the touch control module 33 described in this embodiment is the touch control module 10 described in any one of the above embodiments, and details thereof will not be repeated here.

[0070] In one embodiment, the support layer 31 further includes a support member (not shown in the figure), a support buffer film (not shown in the figure), and a polyimide film (not shown in the figure) that are sequentially stacked, and the display screen layer 32 is specifically disposed on the polyimide film.

[0071] In one embodiment, the cover plate 35 is disposed on a side of the touch control module 33 away from the display screen layer 32, and an adhesive layer 34 is further provided between the cover plate 35 and the touch control module 33. That is, the adhesive layer 34 is specifically disposed on a protective layer (not shown in the figure) in the touch control module 33, and the cover plate is further disposed on the adhesive layer 34.

[0072] Optionally, the adhesive layer 34 may specifically be an OCA (Optically Clear Adhesive) or any other reasonable material layer, and the present application does not make any limitation thereto.

[0073] Optionally, the cover plate 35 may specifically be a CPI (Clear Polyimide) layer, a PET (Polyethylene Terephthalate) layer, or any other reasonable material layer, and the present application does not make any limitation thereto.

[0074] The present application also provides a display device. Please refer to Figure 8 , Figure 8 which is a schematic structural diagram of an embodiment of the display device of the present application. Among them, the display device 40 includes a housing 41 and a display module 42 that are connected to each other.

[0075] Among them, the display module 42 described in this embodiment is specifically the display module 30 described in any one of the above embodiments, and details thereof will not be repeated here.

[0076] Optionally, the display device 40 may specifically be any reasonable display such as a smart phone, a tablet computer, or an in-vehicle display, and the present application does not make any limitation thereto.

[0077] Different from the prior art, in the touch module provided by the present application, the first electrode layer is disposed on the insulating buffer layer, and the color filter layer includes a first light filtering layer, a second light filtering layer, and a third light filtering layer that are spaced apart and disposed on the insulating buffer layer. The first light filtering layer includes a first filling layer and a first insulating dielectric layer. The first insulating dielectric layer covers the first electrode layer, and a groove exposing a part of the first electrode layer is formed on the first insulating dielectric layer. The second electrode layer is further disposed on the bottom and the sidewalls of the first insulating dielectric layer and the groove to connect to the first electrode layer to form a touch sensor. Thus, by integrating the first electrode layer and the second electrode layer into the color filter layer and realizing electrical connection through the groove on the first insulating dielectric layer, the conduction difficulty between the touch electrodes can be effectively reduced, and its dielectric and impedance performance, as well as the manufacturing yield, are improved. Moreover, the touch performance of the touch module is improved, and the risk of process defects is reduced, providing a clear solution for mass production of the process.
