DETAILED DESCRIPTION

[0050] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0051] Referring to Figure 1 Fig. 1, a display module disclosed in the embodiments of the present application is shown, which comprises a display panel 10, a control circuit board 60 and a support 80.

[0052] Specifically, referring to Figure 1 Fig. 2, the display panel 10 comprises a first subunit 11, a second subunit 12 and a third subunit 13 connecting the first subunit 11 and the second subunit 12, and the plane where the first subunit 11 is located intersects the plane where the second subunit 12 is located, that is, the first subunit 11 and the second subunit 12 are in different planes, and the third subunit 13 is a transition part between the first subunit 11 and the second subunit 12.

[0053] Overall, the display panel 10 is roughly in the shape of “L”, so that the display module can be placed at the corner of an object when applied, for example, when the display module is a vehicle-mounted display module, the “L”-shaped display module can be placed in the door, armrest box or operating table of the vehicle, or other positions with corners, so as to make full use of the corner space inside the vehicle to realize various function controls and atmosphere display effects.

[0054] Referring to Figure 1As shown, from the film layer structure, the display panel 10 can include a panel layer 20, a support layer 40 and a cover layer 30. The panel layer 20 is a part of the display panel 10 that emits light, specifically, the panel layer 20 can include a substrate, a driving circuit layer and a light-emitting layer, etc. in sequence. In the embodiment, the substrate can be made of flexible material, such as polyimide, etc. In addition, in the embodiment, the panel layer 20 includes a display part 201, a bending part 202 and a binding part 203. The light emitted by the panel layer 20 is emitted from the display part 201, and the binding part 203 is bent to the backlight side (i.e. the side opposite to the light-emitting direction) through the bending part 202. The bending part 202 and the binding part 203 can include circuit units connected to the devices of the display part 201. The bending part 202 can be coated with a reinforcing glue layer 2021 to protect the bending part 202.

[0055] The driving circuit layer can include at least two thin film transistors and at least one capacitor structure, etc. The thin film transistor can be a top gate type, which can include an active layer, a first gate insulating layer, a gate, a second gate insulating layer, an interlayer dielectric layer, a source and a drain. Specifically, the active layer can be formed on a buffer layer, the first gate insulating layer covers the buffer layer and the active layer, the gate is formed on the side of the first gate insulating layer away from the active layer, the second gate insulating layer covers the gate and the first gate insulating layer, the interlayer dielectric layer covers the second gate insulating layer, and the source and the drain are formed on the side of the interlayer dielectric layer away from the substrate and are respectively located on the opposite sides of the gate. The source and the drain can respectively contact the opposite sides of the active layer through vias (e.g. metal vias). It should be understood that the thin film transistor can also be a bottom gate type.

[0056] The light-emitting layer includes a first pixel electrode and a pixel defining part formed in sequence on the interlayer dielectric layer. It should be understood that the display panel 10 can also include a light-emitting part and a second pixel electrode.

[0057] Specifically, when the thin film transistor is a top gate type, a planarization layer can also be made before forming the light-emitting layer, which can be a single-layer structure or a multi-layer structure; the planarization layer is usually made of organic materials, such as photoresist, acrylic-based polymers, silicon-based polymers, etc. Among them, the first pixel electrode can be electrically connected to the driving transistor in at least two thin film transistors through a via, the first pixel electrode can be an anode, which can be made of materials such as ITO (indium tin oxide), IZO (indium zinc oxide), ZnO (zinc oxide), etc. The pixel defining part can cover the planarization layer, which can be made of organic materials such as photoresist, and the pixel defining part can have a pixel opening exposing the first pixel electrode; the light-emitting part is located in the pixel opening and formed on the first pixel electrode, which can include small molecule organic materials or polymer molecule organic materials, and can be a fluorescent or phosphorescent light-emitting material, which can emit red, green, blue, or white light, etc. Furthermore, according to different needs, the light-emitting part can further include functional layers such as electron injection layer, electron transport layer, hole injection layer, hole transport layer, etc. in different examples; the second pixel electrode covers the light-emitting part, and the polarity of the second pixel electrode is opposite to that of the first pixel electrode; the second pixel electrode can be a cathode, which can be made of metal materials such as lithium (Li), aluminum (Al), magnesium (Mg), silver (Ag), etc.

[0058] Referring to Figure 1 As shown in the figure, the control circuit board 60 is connected with the binding part 203 through the film 70, and the driving chip 71 is arranged on the film 70. The back plate part 203 can realize the electrical connection between the driving chip 71 and the control circuit board 60, and transmit the power signal, control command and image data of the external circuit to the driving chip 71. The driving chip 71 processes the control command and image data and converts them into the control timing sequence of the array substrate to realize the display of the image.

[0059] Therefore, the panel layer 20 can emit light to realize the display of the image.

[0060] Referring to Figure 1 As shown in the figure, the cover plate layer 30 is arranged on the light-emitting side of the panel layer 20, and the cover plate layer 30 completely covers the display part 201 of the panel layer 20. The cover plate layer 30 mainly plays a role of protecting the display part 201 of the panel layer 20, and the cover plate layer 30 and the display part 201 of the panel layer 20 can be connected through the optical adhesive layer 31. The polaroid layer 32 can also be arranged between the cover plate layer 30 and the panel layer 20, which can converge the light emitted by the panel layer 20 to improve the display effect of the display module.

[0061] Referring to Figure 1As shown, the support layer 40 is arranged on the backlight side of the panel layer 20, that is, the side of the display portion 201 away from the cover plate layer 30. The support layer 40 can provide support for the entire display panel 10. The support layer 40 is preferably made of a metal material with good bending performance, such as aluminum or an aluminum alloy material, etc. In the embodiment of the present application, a composite heat dissipation layer 41 is further arranged on the side of the support layer 40 away from the panel layer 20. The composite heat dissipation layer 41 can also be referred to as a super clean film (SCF). The composite heat dissipation layer 41 can include a laminated adhesive layer, a buffer layer and a heat dissipation layer (not shown in the figure). The SCF can be pasted to the panel layer 20 through the adhesive layer. The buffer layer can absorb impact and reduce damage to the panel layer 20 caused by impact. The heat dissipation layer mainly plays a role in heat dissipation and electromagnetic shielding.

[0062] It should be noted that the display panel 10 in the embodiment of the present application can be an active light-emitting display panel, such as an organic light-emitting diode (OLED) display panel, a quantum dot light-emitting diode (QLED) display panel, etc.

[0063] The display panel 10 in the embodiment of the present application can also be a liquid crystal display panel. The present application does not limit the type of display panel. It can be a vertical electric field type liquid crystal display panel, such as a twisted nematic (TN) type liquid crystal display panel or a multi-domain vertical alignment (MVA) type liquid crystal display panel. It can also be a horizontal electric field type liquid crystal display panel, such as a fringe field switching (FFS) type liquid crystal display panel or an in-plane switching (IPS) type liquid crystal display panel.

[0064] In the related art, the control circuit board 60 is generally directly connected to the backlight side of the panel layer 20, that is, connected to the composite heat dissipation layer 41, and the chip on film 70 is also directly connected to the composite heat dissipation layer 41. However, since the display panel 10 has an "L" shape, the control circuit board 60 interferes with the corner portion of the display panel 10, resulting in that the display module cannot be assembled. At the same time, since the control circuit board 60 and the chip on film 70 are directly attached to the backlight side of the display panel 10, local temperature rise is too high, which causes the aging rate of the light-emitting material in this area to be different from that in other areas, resulting in yellowing, which affects the display effect of the display module.

[0065] Therefore, with reference to Figure 1As shown, in the embodiment of the present application, the support 80 is located at the backlight side of the display panel 10, and the support 80 is connected with the backlight side of the display panel 10. It can be understood that the support 80 is located in the space surrounded by the first sub-unit 11 and the second sub-unit 12. Meanwhile, the control circuit board 60 is arranged on the support 80, so that the orthographic projection of the display panel 10 on the first plane does not overlap with the orthographic projection of the control circuit board 60 on the first plane. The first plane is perpendicular to the plane where the first sub-unit is located, and the first plane is also perpendicular to the plane where the second sub-unit is located. In the embodiment of the present application, the first plane can also be understood as the plane where the side wall of the display panel 10 is located (i.e. the plane where the cross section in the figure is located).

[0066] The orthographic projection of the display panel 10 on the first plane does not overlap with the orthographic projection of the control circuit board 60 on the first plane, that is, by connecting the control circuit board 60 on the support 80, the interference problem between the control circuit board 60 and the display panel 10 can be avoided. Meanwhile, the area where the driving chip 71 on the chip on film 70 is located is connected with the support 80, so that the control circuit board 60 and the chip on film 70 are supported by the support 80, and since the control circuit board 60 and the chip on film 70 are not in direct contact with the display panel 10, the problem of local yellowing of the display panel 10 can be reduced.

[0067] Referring to Figure 2 As shown, in an alternative embodiment, the embodiment of the present application provides a display module, in which the support 80 includes a first part 81 and a second part 82.

[0068] Specifically, the first part 81 and the second part 82 are both plate bodies, one side of the first part 81 is connected with one side of the second part 82, and the plane where the first part 81 is located intersects with the plane where the second part 82 is located, so that the cross-sectional shape of the support 80 as a whole is approximately a "V" shape. The first part 81 is connected with the backlight side of the display panel 10, and the control circuit board 60 and the chip on film 70 are connected on the second part 82. It should be noted that the position where the chip on film 70 is connected with the second part 82 is the area where the driving chip 71 is located.

[0069] In the embodiment of the present application, the second part 82 is completely not in contact with the display panel 10, that is, there is no connection relationship between the second part 82 and the display panel 10, and the second part 82 does not overlap the first sub-unit 11, the second sub-unit 12 and the third sub-unit 13 of the display panel 10. Therefore, after the control circuit board 60 is connected to the second part 82, the control circuit board 60 and the display panel 10 will not interfere with each other. At the same time, since the control circuit board 60 is not directly in contact with the display panel 10, the problem of local yellowing of the display panel 10 caused by heat dissipation of the module can be reduced.

[0070] In the embodiment of the present application, the first part 81 is connected to the first sub-unit 11 of the display panel 10 through the first connecting glue layer 84, and the second part 82 extends along the second sub-unit 12 of the display panel 10, but the second part 82 is not in contact with the second sub-unit 12, and a first included angle is formed between the first part 81 and the second part 82, and the size of the first included angle is less than 90°. For example, the size of the first included angle can be greater than or equal to 30° and less than or equal to 60°. If the size of the first included angle is too large, it may be difficult to connect the control circuit board 60 and the thin film 70, and if the size of the first included angle is too small, the second part 82 may interfere with the display panel 10. Therefore, the size of the first included angle should be controlled at an appropriate angle. It should be noted that the specific size of the first included angle can be set according to the shape of the display module, as long as the second part 82 does not interfere with the control circuit board 60 and the display panel 10.

[0071] At the same time, the size (including length, width and thickness) of the first part 81 and the second part 82 of the support 80 can be set according to the size of the actual display product. Generally, the length and width of the first part 81 of the support 80 can be set according to the connection position of the first part 81, and the width of the second part 82 of the support 80 should at least be adapted to the width of the control circuit board 60, so that the control circuit board 60 can be better connected to the support 80. The length of the second part 82 can be slightly less than the length of the control circuit board 60, that is, in the embodiment of the present application, one side edge of the control circuit board 60 exceeds the edge of the second part 82, so as to avoid interference between the second part 82 and the display panel 10. Of course, the length of the second part 82 can also be the same as the length of the control circuit board 60. The thickness of the first part 81 and the second part 82 can be set according to actual needs, as long as the support strength of the support 80 can be ensured while the weight of the entire display module is reduced as much as possible. It should be noted that the size of the support 80 is defined based on the size direction of the display module.

[0072] In addition, with reference to Figure 2As shown, in the embodiment of the present application, the first connecting adhesive layer 84 does not completely fill the area between the first part 81 and the display panel 10, and the first connecting adhesive layer 84 approximately fills 70% of the area between the first part 81 and the display panel 10, so that the use amount of the first connecting adhesive layer 84 can be reduced while the connecting effect is ensured, and the cost is reduced while the weight of the display module is reduced. Of course, the first connecting adhesive layer 84 can also completely fill the area between the first part 81 and the display panel 10. The first connecting adhesive layer 84 can be selected from a pressure-sensitive adhesive.

[0073] In an embodiment, the first part 81 can also be connected to the second subunit 12 through the first connecting adhesive layer 84. The first connecting adhesive layer 84 can be selected from a pressure-sensitive adhesive.

[0074] Referring to Figure 2 As shown, in the embodiment of the present application, the control circuit board 60 and the second part 82 are connected through the second connecting adhesive layer 85.

[0075] Specifically, the second connecting adhesive layer 85 can also be selected from a pressure-sensitive adhesive, and the second connecting adhesive layer 85 also does not completely fill the area between the control circuit board 60 and the second part 82, and the second connecting adhesive layer 85 approximately fills 80% of the area between the second part 82 and the control circuit board 60, so that the use amount of the second connecting adhesive layer 85 can be reduced while the connecting effect is ensured, and the cost is reduced while the weight of the display module is reduced. Of course, the second connecting adhesive layer 85 can also completely fill the area between the second part 82 and the control circuit board 60.

[0076] In order to ensure the ESD (Electro-Static Discharge) performance of the display module, the control circuit board 60 needs to be in communication with the shell of the display module, and for this purpose, referring to Figure 3 As shown, the second connecting adhesive layer 85 includes a connecting part 851 and a plurality of conductive parts 852, wherein the connecting part 851 is the area that mainly plays a connecting effect, and the connecting part 851 can also be understood as a part of adhesive material with adhesion on both sides, and the conductive part 852 is a part of adhesive material with conductive capacity, and the position of the conductive part 852 corresponds to the position of the copper leakage area in the control circuit board 60, that is, the conductive part 852 can realize the connection between the copper leakage area and the second part 82, so that the static electricity charge on the control circuit board 60 can be transmitted to the support 80 through the conductive part 852 of the second connecting adhesive layer 85, and then transmitted to the shell of the display module through the support 80. In the embodiment of the present application, the second connecting adhesive layer 85 includes two conductive parts 852, and the two conductive parts 852 are located on the two sides of the connecting part 851. It can be understood that the number and area of the conductive part 852 are determined according to the number and area of the copper leakage area in the control circuit board 60.

[0077] Referring to Figure 2 As shown, the CTF 70 can be connected with the second part 82 through the foam 87.

[0078] It can be understood that, referring to Figure 4 As shown, the first connecting adhesive layer 84, the second connecting adhesive layer 85 and the foam 87 can be formed on the support 80 before assembly, and a protective film is covered on the first connecting adhesive layer 84, the second connecting adhesive layer 85 and the foam 87 respectively for protection, and the protective film is removed when the assembly is performed, so that the support 80 is connected with the display panel 10, the control circuit board 60 and the CTF 70 respectively.

[0079] In addition, the material of the support 80 can be selected from metal materials or injection molding materials. Exemplarily, the material of the support 80 can be selected from aluminum or aluminum alloy materials, and the material of the support 80 can be selected from PC materials and the like.

[0080] It should be noted that the material of the support 80 should have the ability to conduct electricity to ensure the ESD performance of the display module.

[0081] To this end, referring to Figure 5 As shown, when the display module is selected from injection molding materials, a conductive layer 86 should also be provided on the support 80. The conductive layer 86 covers the side of the support 80 connected with the display panel 10, and the conductive layer 86 covers the side of the support 80 connected with the control circuit board 60, and the conductive layer 86 is a continuous structure. Referring to the drawing, the conductive layer 86 completely covers the first part 81 and the second part 82, and there is no disconnected part in the middle of the conductive layer 86. In this way, the static charge on the control circuit board 60 can be transmitted to the shell part of the display module through the conductive layer 86.

[0082] In an embodiment, referring to Figure 2 As shown, the first part 81 and the second part 82 of the support 80 are integrally formed. That is, the first part 81 and the second part 82 are formed in the mold at the same time, so that there is no connection fracture point between the first part 81 and the second part 82, and the support strength of the support 80 can be better improved.

[0083] In an embodiment, referring to Figure 2 As shown, a chamfer structure is provided at the position where the first part 81 and the second part 82 of the support 80 are connected. The chamfer structure can avoid damaging the film layer structure of the display panel 10 during assembly.

[0084] Referring to Figure 6As shown, in an alternative embodiment, the display module provided by the embodiments of the present application includes a support 80 including a first portion 81, a second portion 82 and a third portion 83.

[0085] Specifically, the first portion 81 and the third portion 83 are connected to the backlight side of the display panel 10, the two ends of the second portion 82 are connected to the first portion 81 and the third portion 83 respectively, and the control circuit board 60 is arranged on the second portion 82. For example, the first portion 81 can be connected to the first sub-unit 11 of the display panel 10 through a first connecting adhesive layer 84, and the third portion 83 can be connected to the second sub-unit 12 of the display panel 10 through the first connecting adhesive layer 84, that is, the second portion 82 is connected to the display panel 10 through the first portion 81 and the third portion 83.
