Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0039] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation manners:
[0040] It should be noted that the front projection mentioned below in the display panel assembly refers to the projection in the vertical direction of the display panel plane. By analogy, all front projections are projections in the vertical direction.
[0041] To solve the above technical problems, as Figures 1 - 4 shown, in the first aspect of the embodiments of the present application, a display module is provided, including:
[0042] A display panel assembly;
[0043] In a specific embodiment, as Figure 1 shown, the display panel assembly includes:
[0044] A display panel 7;
[0045] The display panel 7 of the present invention can be various OLED display panels 7. According to functions, it can be a common OLED display panel 7, a transparent OLED display panel 7, etc.; according to the light-emitting principle, it can be an RGB three-color display panel 7, an OLED display panel 7 with white light + color film, a quantum dot + OLED display panel 7, etc. The present invention does not specifically limit the type of the display panel 7.
[0046] A main support member 8, installed on the backlight side of the display panel 7;
[0047] A printed circuit board 9, installed on the side of the main support member 8 away from the display panel 7, and communicatively connected to the display panel 7 through a flip chip film 14; in a specific embodiment, one end of the flip chip film 14 away from the display panel 7 is bent toward the backlight side of the display panel 7 for communicatively connecting to the printed circuit board 9 to design the display module into a foldable structure to reduce the volume of the display module; specifically, the parameter range of the flexible circuit board 3 is: width: 60 mm - 70 mm, length: 20 mm - 30 mm.
[0048] A polarizer 1, installed on the light-emitting side of the display panel assembly;
[0049] The sensor 2 is installed on the side of the polarizer 1 away from the display panel assembly. Preferably, the sensor 2 is adhered to the side of the polarizer 1 away from the display panel assembly by optical glue. Of course, the connection between the sensor 2 and the polarizer 1 is not limited to the above connection method. As long as the connection method can achieve a stable connection between the sensor 2 and the polarizer 1, it belongs to the protection scope of this embodiment. Moreover, it is communicatively connected to the printed circuit board 9 through the flexible circuit board 3, and is used to transmit the electrical signal generated by the sensor 2 to the printed circuit board 9 through the flexible circuit board 3 to achieve the communication connection between the sensor 2 and the printed circuit board 9. Specifically, the parameter range of the flexible circuit board 3 is: width: 60 mm - 65 mm, length: 40 mm - 45 mm. Preferably, the sensor 2 has the same size as the display panel 7, or the length of the sensor 2 is 0.1 mm - 0.5 mm smaller than the length of the display panel 7.
[0050] In existing small-sized devices such as mobile phones and other wearable devices, the sensor 2 and the display panel assembly are integrated. However, the display module of this application is applied to medium and large-sized devices such as laptop computers, and correspondingly, a design of externally mounting the sensor 2 on the display panel assembly is adopted to facilitate various tests on the sensor 2, especially to ensure the accuracy of the reliability environment test.
[0051] In a preferred embodiment, one end of the flexible circuit board 3 away from the sensor 2 is bent to the backlight side of the display panel assembly for communicative connection with the printed circuit board 9. In this embodiment, the design of the flexible circuit board 3 can enable the display module to be bent at the position of the flexible circuit board 3 to reduce the volume of the display module.
[0052] In a preferred embodiment, there are at least two end portions of the flexible circuit board 3 overlapping with the sensor 2, and the at least two end portions are respectively bound and connected to the bonding area 5. Among them, the two end portions can both be bound and connected to the same side wall surface of the bonding area 5, or the at least two end portions are respectively bound and connected to two opposite wall surfaces of the bonding area 5.
[0053] In a specific embodiment, both the transmitting end (TX) and the receiving end (RX) of the sensor 2 are disposed on the side of the sensor 2 away from the display panel assembly. At this time, in order to ensure that the flexible circuit board 3 is communicatively connected to the transmitting end and the receiving end of the sensor 2 correspondingly, the two ends of the flexible circuit board 3 overlapping with the sensor 2 are communicatively connected to the corresponding transmitting end and receiving end; the installation method of this embodiment is often applied to existing small-sized wearable devices. Taking a mobile phone as an example, when the sensor 2 is integrated with the display panel assembly, both the transmitting end and the receiving end of the sensor 2 are disposed on the side of the sensor 2 away from the display panel assembly. At this time, in order to ensure that the flexible circuit board 3 is communicatively connected to the transmitting end (TX) and the receiving end (RX) of the sensor 2 correspondingly, the end of the flexible circuit board 3 overlapping with the sensor 2 can be correspondingly set to two, or only set to one, so as to realize overlapping with the transmitting end and the receiving end at the same time, and further realize the communication connection between the sensor 2 and the printed circuit board 9. However, in the above design, the transmitting end and the receiving end of the sensor 2 are easily corroded by external environmental factors at the same time, thus affecting the normal use of the sensor 2.
[0054] To solve the above technical problems, as Figure 1 shown, in this embodiment, preferably, the transmitting end and the receiving end of the sensor 2 are correspondingly disposed on two opposite wall surfaces of the sensor 2 through an imprinting process, so as to effectively avoid the simultaneous corrosion of the transmitting end and the receiving end of the sensor 2 by external environmental factors and improve the corrosion resistance of the sensor 2. In order to ensure a stable connection between the flexible circuit board 3 and the transmitting end and the receiving end of the sensor 2 at the same time, in this embodiment, correspondingly, the end of the flexible circuit board 3 overlapping with the sensor 2 is set to two. Specifically, one end is communicatively connected to the transmitting end of the sensor 2, and the other end is communicatively connected to the receiving end of the sensor 2; of course, the end of the flexible circuit board 3 overlapping with the sensor 2 is not limited to the above two designs, and the corresponding number is adapted to the number of the transmitting end and the receiving end of the sensor 2 to be overlapped. When the number of the transmitting end and the receiving end of the sensor 2 to be overlapped is multiple, correspondingly, the end of the flexible circuit board 3 overlapping with the sensor 2 is also correspondingly set to multiple.
[0055] The cover plate 4 covers the side of the sensor 2 away from the polarizer 1 and is used to protect multiple film layers in the display module. Preferably, the cover plate 4 is adhered to the side of the sensor 2 facing away from the polarizer 1 by an optical adhesive. Of course, the connection between the cover plate 4 and the sensor 2 is not limited to the above connection method, and any connection method that can achieve a stable connection between the cover plate 4 and the sensor 2 belongs to the protection scope of this embodiment. A cover film is provided on the outer side of the cover plate. Preferably, a high-viscosity adhesive is provided on the side of the cover film 6 close to the sensor, and the cover film 6 is stably connected to the sensor through the high-viscosity adhesive. Of course, the connection between the cover film 6 and the sensor is not limited to the above connection method, and any connection method that can achieve a stable connection between the cover film 6 and the sensor belongs to the protection scope of this embodiment. In summary, on the one hand, this application adopts the method of externally mounting the sensor on the display panel assembly to meet the usage requirements of medium and large-sized products. On the other hand, this application adopts the method of cooperating the sensor with the cover film to avoid the situation of being corroded by water and oxygen during the reliability environmental test of the sensor.
[0056] In another preferred embodiment, there is a gap between one edge of the cover plate in the orthographic projection of the display panel assembly and one edge of the sensor in the orthographic projection of the display panel assembly to expose the bonding area of the sensor, and the cover film covers the outside of the bonding area.
[0057] In summary, when the display module of this embodiment is applied to a folding product, taking the inner-fold design as an example for illustration, at this time, the display surface is the inner diameter of the bend, and the rear shell 11 is the outer diameter of the bend. From the specific perspective of the OLED display module, that is, the cover plate 4 is on the innermost side. Compared with other film layers, the bending stress borne by the cover plate 4 is the greatest. At this time, if designed conventionally and the cover plate 4 expands outward relative to the lower film layer, during the bending process of the product, wrinkles will occur at the edge of the cover plate 4. Especially for medium and large-sized products, the bending stress is greater, and the wrinkles of the cover plate 4 are more serious. The wrinkles will not only affect the visual effect of the product but also affect the folding performance. To solve the above technical problems, this embodiment adopts Figure 1As shown, the lower edge of the cover plate 4 is retracted relative to the lower film layer so that the cover plate 4 avoids the bending position. In a specific embodiment, the above gap ranges from 3 mm to 5 mm, so that the length range of the exposed sensor 2 bonding area 5 is from 3 mm to 5 mm; specifically, the setting range of the cover film 6 is equal to the setting range of the bonding area 5 of the sensor 2. Further, in order to facilitate the bending of the display module in the direction close to the cover plate 4, preferably, there is a gap between the cover film 6 and the cover plate 4; furthermore, in a preferred embodiment, the cover film 6 also overlaps with a part of the flexible circuit board 3 to improve the connection stability between the cover film 6 and the bonding area 5, and to prevent the cover film 6 and the bonding area 5 from being misaligned when the display module moves in the inner folding or outer folding direction close to or away from the cover plate 4, thereby improving the protection stability of the cover film 6 for the bonding area 5.
[0058] In a preferred embodiment, in order to ensure the light conduction effect, preferably, the cover film 6 is provided with a transparent structure, and on the premise of ensuring the water and oxygen isolation effect for the bonding area 5 of the sensor 2, it is ensured that the light emitted by the display panel 7 can be stably transmitted.
[0059] In summary, in this embodiment, the method of adding the cover film 6 to the exposed bonding area 5 of the sensor 2 is adopted to protect the bonding area 5 of the sensor 2, so as to avoid the situation of being corroded by water and oxygen during the reliability environmental test.
[0060] In a specific embodiment, the cover film 6 is set as the insulating layer 13. Preferably, the insulating layer 13 is set as an insulating PET film. Of course, the insulating layer 13 is not limited to being made of the above materials, and any material with insulating properties is within the protection scope of this embodiment. Exemplarily, the insulating layer 13 can also be set as a PBT film.
[0061] In the prior art, when the display module is attacked by external static electricity, it will cause damage to the exposed sensor 2. When the static electricity conducts to the inside of the sensor 2, the situation that the sensor 2 channel is burned out by static electricity will occur. Therefore, it is particularly important to carry out electrostatic protection design for the sensor 2.
[0062] Therefore, in order to improve the antistatic ability of the bonding area 5 of the sensor 2, in another preferred embodiment, as Figure 4As shown, the covering film 6 includes: an insulating layer 13 and a first conductive layer 10 which are stacked in sequence from bottom to top. Preferably, the first conductive layer 10 can be set to but not limited to conductive cloth, copper foil, and aluminum foil, etc. As long as the material can achieve static electricity conduction, it is suitable for this embodiment and belongs to the protection scope of this embodiment. In summary, in this embodiment, the design of adding a first conductive layer 10 above the insulating layer 13 can conduct static electricity generated during anti-static testing or actual use of the product, thereby effectively reducing the impact of static electricity on the binding area 5 of the sensor 2, thereby avoiding the situation where the sensor 2 channel is damaged by static electricity.
[0063] In a preferred embodiment, the orthographic projection of the first conductive layer 10 on the display panel assembly falls within the orthographic projection of the insulating layer 13 on the display panel assembly; or, the orthographic projection of the first conductive layer 10 on the display panel assembly covers the orthographic projection of the insulating layer 13 on the display panel assembly; theoretically, as long as part of the first conductive layer 10 is in conflict with the insulating layer 13, the electrostatic desorption of the sensor 2 can be achieved. In this embodiment, for the convenience of processing and to ensure the electrostatic desorption effect, preferably, the size of the first conductive layer 10 is equal to the size of the insulating layer 13, and the parameter setting range is as follows: length: 60mm-65mm; width: 1.5mm-2.5mm.
[0064] Furthermore, when one side of the covering film 6 overlaps a portion of the flexible circuit board 3 , the width of the first conductive layer 10 is greater than or equal to the width of the flexible circuit board 3 , so that the static electricity borne by the binding area 5 of the sensor 2 and the flexible circuit board 3 can be discharged through the first conductive layer 10 .
[0065] In a preferred embodiment, the display module also includes: a rear shell 11 for protecting the entire display module, one end of the rear shell 11 is connected to the cover plate 4, and the other end is bent to the backlight side of the display module to cover the binding area 5 of the sensor 2 and the flexible circuit board 3.
[0066] In a preferred embodiment, a second conductive layer 12 is further provided on the rear shell 11, and the second conductive layer 12 is in contact with the first conductive layer 10. Specifically, the second conductive layer 12 can be set to but not limited to conductive cloth, copper foil and aluminum foil, etc. Preferably, the second conductive layer 12 can be set to conductive glue sprayed on the inner wall of the rear shell 11, which can ensure that it cooperates with the first conductive layer 10 to enhance the antistatic ability of the sensor 2, and can achieve a stable connection with the first conductive layer 10. In summary, as long as the material can achieve static electricity conduction, it is suitable for this embodiment and belongs to the protection scope of this embodiment. In summary, in this embodiment, by adding a second conductive layer 12 to the inner wall of the rear shell 11, the static electricity that cannot be conducted by the first conductive layer 10 is conducted through the second conductive layer 12, thereby improving the antistatic performance of the terminal product.
[0067] In a specific embodiment, the positive projection of the second conductive layer 12 on the display panel assembly at least covers the positive projection of the first conductive layer 10 within the display panel assembly; preferably, as Figure 1 shown, the setting range of the second conductive layer 12 is to cover the part of the flexible circuit board 3 near the light-emitting side of the display panel assembly and the bending area, and, preferably, the second conductive layer 12 is in contact with the part of the flexible circuit board 3 near the light-emitting side of the display panel assembly and the bending area to achieve the conduction of the static electricity generated by the sensor 2 and the entire flexible circuit board 3; in another preferred embodiment, there is a gap between the second conductive layer 12 and the bending area of the flexible circuit board 3, and this gap can be used to arrange the antenna. At this time, the design of the second conductive layer 12 will facilitate the conduction of the antenna signal.
