DETAILED DESCRIPTION
[0050] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0051] Reference Figure 1 As shown, a display module disclosed in an embodiment of the present application includes a display panel 10 , a control circuit board 60 and a support member 80 .
[0052] Specifically, refer to Figure 1 As shown, the display panel 10 includes 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 with 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 "L"-shaped, so that the display module can be placed at the corner of an object when used. For example, when the display module is a vehicle-mounted display module, the "L"-shaped display module can be placed in a vehicle door, armrest box, or operating table and other locations with corners, thereby making full use of the corner space inside the vehicle to achieve various function controls and atmosphere display effects.
[0054] Reference Figure 1As shown, from the perspective of the film layer structure, the display panel 10 may include a panel layer 20, a support layer 40, and a cover plate layer 30. Among them, the panel layer 20 is the part of the display panel 10 that emits light. Specifically, the panel layer 20 may include a substrate, a driving circuit layer, a light-emitting layer, etc., which are stacked in sequence. In the embodiment of the present application, since the display panel 10 is irregular in shape, the substrate may be made of a flexible material, such as polyimide. In addition, in the embodiment of the present application, the panel layer 20 includes a display portion 201, a bending portion 202, and a bonding portion 203. The light emitted by the panel layer 20 is emitted from the display portion 201, and the bonding portion 203 is bent to the backlight side (i.e., the side opposite to the light-emitting direction) through the bending portion 202. The bending portion 202 and the bonding portion 203 may include circuit units connected to the respective devices of the display portion 201. A reinforcing adhesive layer 2021 may be coated on the bending portion 202 to protect the bending portion 202.
[0055] The driving circuit layer may include at least two thin-film transistors and at least one capacitor structure, etc. The thin-film transistor may be a top-gate type. This thin-film transistor may include an active layer, a first gate insulating layer, a gate electrode, a second gate insulating layer, an interlayer dielectric layer, a source electrode, and a drain electrode. Specifically, the active layer may be formed on the buffer layer, the first gate insulating layer covers the buffer layer and the active layer, the gate electrode is formed on the side of the first gate insulating layer away from the active layer, the second gate insulating layer covers the gate electrode and the first gate insulating layer, the interlayer dielectric layer covers the second gate insulating layer, and the source electrode and the drain electrode are formed on the side of the interlayer dielectric layer away from the substrate and are respectively located on opposite sides of the gate electrode. The source electrode and the drain electrode may be in contact with opposite sides of the active layer through vias (e.g., metal vias). It should be understood that this thin-film transistor may also be a bottom-gate type.
[0056] The light-emitting layer includes a first pixel electrode and a pixel defining portion formed in sequence on the interlayer dielectric layer. It should be understood that the display panel 10 may further include a light-emitting portion and a second pixel electrode.
[0057] Specifically, when the thin-film transistor is of the top-gate type, a planarization layer can be fabricated before forming the light-emitting layer. This planarization layer can be a single-layer structure or a multi-layer structure; this planarization layer is usually made of organic materials, such as: photoresist, acrylic-based polymers, silicon-based polymers and other materials. Among them, the first pixel electrode can be electrically connected to the driving transistor among at least two thin-film transistors through a via. This first pixel electrode can be an anode, and this anode can be made of materials such as ITO (indium tin oxide), indium zinc oxide (IZO), zinc oxide (ZnO), etc.; the pixel defining part can cover the planarization layer, and this pixel defining part can be made of organic materials, such as: organic materials such as photoresist, and there can be a pixel opening in the pixel defining part that exposes the first pixel electrode; the light-emitting part is located within the pixel opening and formed on the first pixel electrode. This light-emitting part can include small molecule organic materials or polymer molecule organic materials, can be a fluorescent light-emitting material or a phosphorescent light-emitting material, can emit red light, green light, blue light, or can emit white light, etc.; and, according to actual different needs, in different examples, the light-emitting part can further include functional layers such as an electron injection layer, an electron transport layer, a hole injection layer, a hole transport layer, etc.; the second pixel electrode covers the light-emitting part, and the polarity of this second pixel electrode is opposite to the polarity of the first pixel electrode; this second pixel electrode can be a cathode, and this cathode can be made of metal materials such as lithium (Li), aluminum (Al), magnesium (Mg), silver (Ag), etc.
[0058] Referring to Figure 1 As shown, the control circuit board 60 is connected to the bonding part 203 through a chip-on-film 70, and a driving chip 71 is provided on the chip-on-film 70. The backplane 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, image data, etc. of the external circuit to the driving chip 71. After processing the control command and image data, the driving chip 71 converts them into the control timing of the array substrate to realize the display of the image.
[0059] Thus, light can be emitted through the panel layer 20, thereby realizing the display of the image.
[0060] Referring to Figure 1 As shown, the cover layer 30 is provided on the light-emitting side of the panel layer 20. The cover layer 30 completely covers the display part 201 of the entire panel layer 20. The cover layer 30 mainly serves to protect the display part 201 of the panel layer 20. The cover layer 30 and the display part 201 of the panel layer 20 can be connected through an optical adhesive layer 31. A polarizer layer 32 can also be provided between the cover layer 30 and the panel layer 20. The polarizer layer 32 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 disposed on the backlight side of the panel layer 20, that is, on the side where the display portion 201 faces away from the cover plate layer 30. The support layer 40 can provide a support effect 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 aluminum alloy material, etc. In the embodiment of the present application, a composite heat dissipation layer 41 is further disposed 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 SCF (super clean film). It can include: a stacked adhesive layer, a buffer layer, and a heat dissipation layer (not shown in the figure). Among them, the SCF and the panel layer 20 can be pasted through the adhesive layer. The function of the buffer layer is to absorb impacts and reduce damage to the panel layer 20 caused by impacts. The heat dissipation layer mainly plays the role of 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 Diodes (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 the 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, a Multi-domain Vertical Alignment (MVA) type liquid crystal display panel, or 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 flip chip film 70 is also directly connected to the composite heat dissipation layer 41. However, since the shape of the display panel 10 is "L" shaped, interference occurs between the control circuit board 60 and the corner portion of the display panel 10, resulting in the inability to complete the assembly of the display module. At the same time, since the control circuit board 60 and the flip chip film 70 are directly attached to the backlight side of the display panel 10, local temperature rise is too high, resulting in different aging rates of the light-emitting materials in this area from other areas and yellowing, affecting the display effect of the display module.
[0065] For this reason, referring to Figure 1As shown, in the embodiment of the present application, a support member 80 is provided. The support member 80 is located on the backlight side of the display panel 10, and the support member 80 is connected to the backlight side of the display panel 10. It can be understood that the support member 80 is located within the space enclosed by the first sub-unit 11 and the second sub-unit 12. At the same time, the control circuit board 60 is disposed on the support member 80 such 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. Here, the first plane is perpendicular to the plane where the first sub-unit is located and 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 of the cross-section in the figure).
[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 to say, by connecting the control circuit board 60 to the support member 80, interference problems between the control circuit board 60 and the display panel 10 can be avoided. At the same time, the area where the driving chip 71 is located on the COF film 70 is connected to the support member 80. In this way, the support member 80 supports the control circuit board 60 and the COF film 70, and since the control circuit board 60 and the COF film 70 do not directly contact the display panel 10, the problem of local yellowing of the display panel 10 can be reduced.
[0067] Refer to Figure 2 As shown, in an alternative embodiment, the embodiment of the present application provides a display module. In this display module, the support member 80 includes a first part 81 and a second part 82.
[0068] Specifically, both the first part 81 and the second part 82 are plate bodies. One side of the first part 81 is connected to 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, such that the overall cross-sectional shape of the support member 80 is approximately a "V" shape. The first part 81 is connected to the backlight side of the display panel 10, while the control circuit board 60 and the COF film 70 are connected to the second part 82. It should be noted that the position where the COF film 70 is connected to the second part 82 is the area where the driving chip 71 is located.
[0069] Moreover, in the embodiment of the present application, the second part 82 is completely not in contact with the display panel 10. That is to say, there is no connection relationship between the second part 82 and the display panel 10, and the second part 82 does not overlap with the first sub-unit 11, the second sub-unit 12, and the third sub-unit 13 of the display panel 10. Therefore, after connecting the control circuit board 60 to the second part 82, interference between the control circuit board 60 and the display panel 10 can be avoided. 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 problems 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 in the display panel 10 through the first connection adhesive layer 84. The second part 82 extends along the second sub-unit 12 in 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. The size of the first included angle is less than 90°. Exemplarily, 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 cause difficulties in connecting the control circuit board 60 and the COF film 70. If the size of the first included angle is too small, it may cause interference between the second part 82 and 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 it can prevent interference between the second part 82, the control circuit board 60, and the display panel 10.
[0071] Meanwhile, the dimensions (including length, width, and thickness) of the first part 81 and the second part 82 can be set according to the size of the actual display product. Generally speaking, the length and width of the first part 81 in the support 80 can be set according to the connection position of the first part 81. The width of the second part 82 in the support 80 should be at least 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. As for the length of the second part 82, it can be slightly less than the length of the control circuit board 60. That is to say, in the embodiment of the present application, one side edge of the control circuit board 60 extends beyond the edge of the second part 82 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 thicknesses of the first part 81 and the second part 82 can be set according to actual requirements, as long as the support strength of the support 80 can be ensured while minimizing the weight of the entire display module as much as possible. It should be noted that the dimensions of the support 80 are all 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 connection adhesive layer 84 does not completely fill the area between the first part 81 and the display panel 10. The first connection adhesive layer 84 roughly fills 70% of the area between the first part 81 and the display panel 10. This can ensure the connection effect between the two while reducing the amount of the first connection adhesive layer 84, reducing costs and lightening the weight of the display module. Of course, the first connection adhesive layer 84 can also completely fill the area between the first part 81 and the display panel 10. The first connection adhesive layer 84 can be a pressure-sensitive adhesive.
[0073] In one embodiment, the first part 81 can also be connected to the second sub-unit 12 through the first connection adhesive layer 84. Among them, the first connection adhesive layer 84 can be a pressure-sensitive adhesive.
[0074] Refer to Figure 2 As shown, in the embodiment of the present application, the control circuit board 60 is connected to the second part 82 through the second connection adhesive layer 85.
[0075] Specifically, the second connection adhesive layer 85 can also be a pressure-sensitive adhesive. At the same time, the second connection adhesive layer 85 does not completely fill the area between the control circuit board 60 and the second part 82. The second connection adhesive layer 85 roughly fills 80% of the area between the second part 82 and the control circuit board 60. This can ensure the connection effect between the two while reducing the amount of the second connection adhesive layer 85, reducing costs and lightening the weight of the display module. Of course, the second connection adhesive layer 85 can also completely fill the area between the second part 82 and the control circuit board 60.
[0076] To ensure the ESD (Electro-Static Discharge) performance of the display module, the control circuit board 60 needs to be connected to the housing of the display module. For this purpose, refer to Figure 3 As shown, the second connection adhesive layer 85 includes a connection part 851 and a plurality of conductive parts 852. Among them, the connection part 851 is the area that plays the main connection effect. The connection part 851 can also be understood as the adhesive part with adhesiveness on both sides, while the conductive part 852 is the adhesive part with conductivity. 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 to say, the conductive part 852 can realize the connection between the copper leakage area and the second part 82. In this way, the static charge on the control circuit board 60 can be transferred to the support 80 through the conductive part 852 of the second connection adhesive layer 85, and then transferred to the housing of the display module through the support 80. In the embodiment of the present application, the second connection adhesive layer 85 includes two conductive parts 852, and the two conductive parts 852 are respectively located on both sides of the connection part 851. It can be understood that the number and area of the conductive parts 852 are determined according to the number and area of the copper leakage areas in the control circuit board 60.
[0077] Referring to Figure 2 as shown, the flip-chip film 70 and the second part 82 can be connected by a foam 87.
[0078] It can be understood that referring to Figure 4 as shown, the first adhesive layer 84, the second adhesive layer 85 and the foam 87 can all be formed on the support 80 before assembly, and a protective film is covered on the first adhesive layer 84, the second adhesive layer 85 and the foam 87 respectively for protection. When assembling, the protective film is torn off to realize the connection between the support 80 and the display panel 10, the control circuit board 60 and the flip-chip film 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, etc.
[0080] It should be noted that the material of the support 80 should have conductivity to ensure the ESD performance of the display module.
[0081] For this reason, referring to Figure 5 as shown, when the injection molding material is selected for the display module, a conductive layer 86 should also be provided on the support 80. While covering the side of the support 80 connected to the display panel 10, the conductive layer 86 covers the side of the support 80 connected to the control circuit board 60, and the conductive layer 87 is a continuous structure. Referring to the figure shown, the conductive layer 86 completely covers the first part 81 and completely covers the second part 82, and there is no disconnected part in the middle of the conductive layer 86. In this way, the static charges on the control circuit board 60 can be transferred to the housing part of the display module through the conductive layer 86.
[0082] In one 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 to say, the first part 81 and the second part 82 are formed simultaneously in the mold, so that there is no connection break 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 one embodiment, referring to Figure 2 as shown, a chamfer structure is provided at the connection position between the first part 81 and the second part 82 of the support 80. The setting of the chamfer structure can prevent the support 80 from damaging the film layer structure of the display panel 10 during the assembly process.
[0084] Referring to Figure 6As shown, in an alternative embodiment, the embodiment of the present application provides a display module. In this display module, the support member 80 includes 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. Both ends of the second portion 82 are respectively connected to the first portion 81 and the third portion 83, and the control circuit board 60 is disposed on the second portion 82. Exemplarily, the first portion 81 may be connected to the first sub-unit 11 of the display panel 10 through a first adhesive layer 84, and the third portion 83 may be connected to the second sub-unit 12 of the display panel 10 through the first adhesive layer 84. That is to say, the second portion 82 is connected to the display panel 10 through the first portion 81 and the third portion 83. This can improve the connection stability between the support member 80 and the display panel 10, so as to reduce the situation where the support member 80 is detached from the display panel 10 after long-term use. The first portion 81, the second portion 82, and the third portion 83 of the support member 80 may be integrally formed.
[0086] Among them, the second portion 82 is completely not in contact with the display panel 10. That is to say, there is no connection relationship between the second portion 82 and the display panel 10, and the second portion 82 does not overlap with the first sub-unit 11, the second sub-unit 12, and the third sub-unit 13 of the display panel 10. Therefore, after connecting the control circuit board 60 to the second portion 82, it can be ensured that there is no interference between the control circuit board 60 and the display panel 10. At the same time, since the control circuit board 60 is not directly in contact with the display panel 10, it can reduce the problem of local yellowing of the display panel 10 caused by the heat dissipation problem of the module.
[0087] Refer to Figure 7 As shown, in an alternative embodiment, the embodiment of the present application provides a display module. In this display module, the support member 80 includes a first portion 81, a second portion 82, and a third portion 83.
[0088] Specifically, the first part 81 and the third part 83 are connected to the backlight side of the display panel 10. The second part 82 is connected to the first part 81 or the third part 83, and the control circuit board 60 is disposed on the second part 82. Exemplarily, the first part 81 can be connected to the first sub-unit 11 of the display panel 10 through the first adhesive layer 84, and the third part 83 can be connected to the second sub-unit 12 of the display panel 10 through the first adhesive layer 84. In this embodiment, the first part 81 and the third part 83 are connected to each other, and the second part 82 only needs to be connected to the first part 81 or the third part 83. This can improve the connection stability between the support member 80 and the display panel 10, so as to reduce the situation that the support member 80 is separated from the display panel 10 after long-term use. The first part 81, the second part 82, and the third part 83 of the support member 80 can be integrally formed.
[0089] Among them, the second part 82 is not in contact with the display panel 10 at all, that is to say, there is no connection relationship between the second part 82 and the display panel 10, and the second part 82 does not overlap with the first sub-unit 11, the second sub-unit 12, and the third sub-unit 13 of the display panel 10. Therefore, after connecting the control circuit board 60 to the second part 82, interference between the control circuit board 60 and the display panel 10 can be avoided. 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 the heat dissipation problem of the module can be reduced.
[0090] Referring to Figure 8 As shown, in one embodiment, the control circuit board 60 can be a flexible circuit board, and the flexible circuit board is directly connected to the bonding part 203 of the panel layer 20. At this time, the driving chip 71 is located on the bonding part 203, and the area where the foam 87 is connected to the control circuit board 60 can be used to place any components on the flexible circuit board, and the components can be protected by the area formed by the foam 87 and the control circuit board 60.
