[0002] In related technologies, antennas are designed at the upper and lower ends of the middle frame structure of electronic devices. With the development of full-screen technology, the display module driver chip and related driver circuits, and thin-film transistors (TFT, Thin Film Transistor) are getting closer and closer to the edge of the display module, which means that the display module driver circuit and driver integrated circuit (IC, Integrated Circuit) are greatly shortened from the distance to the middle frame antenna, resulting in greater electromagnetic interference between the antenna and the display module.

[0003] At present, in order to reduce the electromagnetic interference of the display module to the antenna, an electrostatic shielding layer is set on the display module, which can reduce the electromagnetic interference of the display module to the antenna. However, the added shielding layer makes the original display module structure more complicated, increasing the difficulty of manufacturing the display module. Summary of the invention

[0021] Combine the following Figures 1 to 5 As shown, a display module 100 and an electronic device 220 according to an embodiment of the present application are described.

[0022] The present application embodiment provides a display module 100, such as Figure 1 and Figure 2 As shown, the display module 100 includes a substrate 110, a first electrode layer 136, a light-emitting layer 120, a second electrode layer 132 and a shielding layer 134. The substrate 110 has a first region 112 and a second region 114; the first electrode layer 136 is disposed on the substrate and located in the first region 112; the light-emitting layer 120 is disposed on the first electrode layer 136 and located in the first region 112; the second electrode layer 132 is disposed on the light-emitting layer 120, electrically connected to the light-emitting layer 120, and located in the first region 112; the shielding layer 134 is arranged at intervals from the first electrode layer 136 or the second electrode layer 132, and covers at least a portion of the second region 114.

[0023] The present application proposes a display module 100, including a substrate 110 and a light-emitting layer 120. The substrate 110 is divided into two regions, a first region 112 and a second region 114. The light-emitting layer is located in the first region 112, and the light-emitting layer 120 is used to display images and provide light. The first electrode layer 136 is arranged on the substrate, located in the first region 112, the light-emitting layer 120 is arranged on the first electrode layer 136, and is electrically connected to the first electrode layer 136, the second electrode layer 132 is arranged on the light-emitting layer 120, and is electrically connected to the light-emitting layer 120, the first electrode layer 136 and the second electrode layer 132 are used to conduct current to ensure circuit connectivity. The shielding layer 134 is arranged in the same layer as the first electrode layer 136 or the second electrode layer 132, the first electrode layer 136 and the second electrode layer 132 are electrically connected to the light-emitting layer 120, and are the cathode and anode of the light-emitting layer 120. The present application reduces the electromagnetic intermodulation interference of the display module 100 on the TRX (Transfer & Receive) of the antenna 250 through the setting of the shielding layer 134, improves the signal-to-noise ratio of the antenna 250, reduces the risk of the display module 100 being interfered by the antenna 250, improves the reliability of the display module 100, and also improves the stability of the antenna 250 signal, thereby improving the user experience. At the same time, the present application sets the shielding layer 134 and the first electrode layer 136 or the second electrode layer 132 on the same layer. When manufacturing the display module 100, the shielding layer 134 is designed to be at the same layer as the first electrode layer 136 or the second electrode layer 132, and the shielding layer 134 in the corresponding area is manufactured using the first electrode layer 136 or the second electrode layer 132. The manufacturing is completed through integration, and the shielding layer 134 is embedded in the display module 100 without adding additional costs and manufacturing processes, and the number of layers of the display module 100 will not increase due to the addition of the shielding layer 134. The structure and manufacturing process of the display module 100 are simplified, and the production efficiency of the product is improved.

[0024] Specifically, the shielding layer 134 is provided in the second area 114 of the display module 100, which can reduce the electromagnetic interference of the antenna 250. If it is an organic light-emitting diode (OLED, Organic Light-Emitting Diode) display screen, the shielding layer 134 covers at least part of the second area 114, and the electromagnetic interference improvement effect is particularly obvious. The present application designs the shielding layer 134 directly to the first electrode layer 136 or the second electrode layer 132 of the OLED light-emitting material, and uses the first electrode layer 136 or the second electrode layer 132 to manufacture the shielding layer 134 of the corresponding area, completes the manufacturing through integration, and is embedded in the display (LCM, Liquid Crystal Multiple) module, without cost increase, making the product more competitive in the market.

[0025] At the same time, by using the first electrode layer 136 or the second electrode layer 132 to manufacture the shielding layer 134 of the corresponding area, the manufacturing is completed through integration, which does not increase the manufacturing cost of the product, so that the user does not need to spend extra costs during later maintenance and replacement, which provides protection for the after-sales of the product.

[0026] At the same time, by using the first electrode layer 136 or the second electrode layer 132 to manufacture the shielding layer 134 of the corresponding area, the manufacturing is completed through integration. The number of layers of the display module 100 is not increased due to the addition of the shielding layer 134, so that the thickness of the electronic device 220 is guaranteed, thereby improving the market competitiveness of the product.

[0027] Specifically, the first electrode layer 136 and the second electrode layer 132 are both conductive layers.

[0028] According to some embodiments of the present application, optionally, Figure 1 , Figure 2 and Figure 3 As shown, the bending region 116 is a partial region of the second region 114 , and the shielding layer 134 covers the bending region 116 .

[0029] In this embodiment, the bending region 116 is a part of the second region 114, and the shielding layer 134 covers the bending region 116. The bending region 116 is closer to the antenna 250, and the shielding layer 134 is arranged in the bending region 116 to further reduce the interference of the display module 100 to the antenna 250.

[0030] According to some embodiments of the present application, optionally, Figure 3 As shown, the shielding layer 134 extends to the second region 114 except the bending region 116 .

[0031] In this embodiment, the shielding layer 134 extends to the area of ​​the second area 114 except the bending area 116. If the film layer with differences is only manufactured in a fixed small area, stress is easily generated, and the transition partition cannot be manufactured in the process. Under the premise of controlling the thickness of the film layer, the shielding layer 134 is extended to the non-effective display (AA, Active Area) area, which helps to improve the reliability after bending. Among them, the AA area refers to the operable area of ​​the thin film transistor (TFT, Thin Film Transistor) liquid crystal screen, that is, the touchable area.

[0032] Specifically, the display module 100 is an organic light-emitting diode (OLED) module. The present application sets a shielding layer 134 in the complete area corresponding to the OLED module. The shielding layer 134 uses indium tin oxide (ITO), or tin-doped indium oxide material, or magnesium-silver alloy (AgMg), covers the bending area 116 of the display module 100 to the flexible printed circuit board 244 bonding (FPC bonding, flexible print circuit bonding) area, and is connected to the zero potential reference level of the panel to form a ground shield. Through the electromagnetic shielding principle, the electromagnetic intermodulation interference between the antenna 250 and the display drive circuit 240 is reduced, and the signal quality of the electronic device 220 is improved.

[0033] Furthermore, the present application adds a shielding layer 134 as the basic principle of electromagnetic barrier. Based on the existing OLED film process and material characteristics, the conductive layer is mainly a metal alloy layer (cathode) or ITO (anode) and other metal (Metal) wiring. For example, metal 1 / metal 2 are molybdenum (Mo, Molybdenum) and titanium-aluminum-titanium (TiAlTi, Titanium-Aluminum-Titanium), so the embodiment of the present application uses a conventional isolation design and a new mask design to replace the use of an open mask (OPEN MASK) as a cathode, which can form a shielding layer 134 for the integrated circuit (IC, Integrated Circuit) and the bending area and the entire lower frame area. Or when making the anode contact layer ITO, the mask design is also used to adopt the shielding layer 134 style design corresponding to the lower frame. When the process film layer is manufactured, a complete shielding layer 134 can be formed in an integrated manner without adding additional costs and manufacturing processes.

[0034] According to some embodiments of the present application, optionally, Figure 1 and Figure 2As shown, the base 110 includes a substrate 140, a buffer layer 150, a first doping layer 160, a second doping layer 170, an insulating layer 180, a planar layer 190 and a driver 200. The buffer layer 150 is disposed on the substrate 140; the first doping layer 160 is disposed on the side of the buffer layer 150 away from the substrate 140; the second doping layer 170 is disposed on the side of the buffer layer 150 away from the substrate 140, and is arranged in parallel with the first doping layer 160; the insulating layer 180 is disposed on the side of the first doping layer 160 and the second doping layer 170 away from the substrate 140; the planar layer 190 is disposed on the side of the insulating layer 180 away from the substrate 140, and the anode of the light-emitting layer 120 is disposed on the side of the planar layer 190 away from the substrate 140; the driver 200 is disposed on the insulating layer 180 and the planar layer 190, and is electrically connected to the anode of the light-emitting layer 120.

[0035] In this embodiment, the base 110 includes a base substrate 140, a buffer layer 150, a first doping layer 160, a second doping layer 170, an insulating layer 180, a flat layer 190 and a driver 200. The buffer layer 150 is disposed on the base substrate 140. The base substrate 140 is a basic component of the display module 100 and provides support for other functional layers. At the same time, the base substrate 140 can also help control the pixel arrangement, and the base substrate 140 can prevent leakage and other situations. The buffer layer 150 can reduce the damage to the display module 100 caused by external impact, and can also play a role in flattening and isolation. The first doping layer 160 is disposed on the side of the buffer layer 150 away from the base substrate 140, and the second doping layer 170 is disposed on the side of the buffer layer 150 away from the base substrate 140, and is arranged in parallel with the first doping layer 160. The first doping layer 160 is an N-type doping layer or a P-type doping layer, and the second doping layer 170 is another type of the first doping layer 160. The N-type doped layer and the P-type doped layer realize the transmission of charges, which plays a key role in the light-emitting function of the display module 100. The insulating layer 180 is arranged on the side of the first doped layer 160 and the second doped layer 170 away from the base substrate 140. The first doped layer 160 and the second doped layer 170 can form a PN combination for conductivity. The insulating layer 180 mainly prevents the current from flowing in unnecessary places, and plays the role of electrical isolation and protection. The flat layer 190 is arranged on the side of the insulating layer 180 away from the base substrate 140, and the anode of the light-emitting layer 120 is arranged on the side of the flat layer 190 away from the base substrate 140. The flat layer 190 can make the surface of the display module 100 more flat and smooth, providing a good adhesion basis for subsequent functional layers, which is conducive to improving the display effect. The driver 200 is disposed on the insulating layer 180 and the planar layer 190 and is electrically connected to the anode of the light-emitting layer 120 . The driver 200 is a thin film transistor (TFT) and is an active matrix driver 200 of the display module 100 , which is used to accurately control the current of each pixel point and improve the imaging quality of the display module 100 .

[0036] Furthermore, the insulating layer 180 is provided with a gate 172, a drain 174 and a source 176. The gate 172 is a component of the thin film transistor and is used to control the switch of the pixel circuit so that the display module 100 can accurately display images. In the field effect transistor of the electronic device, the drain 174 is the end where the current flows out, and the source 176 is the end where the current flows in.

[0037] Furthermore, a Polly layer is provided between the buffer layer 150 and the insulating layer 180 , and the Polly layer is arranged in parallel with the first doping layer 160 and the second doping layer 170 .

[0038] According to some embodiments of the present application, optionally, Figure 1 and Figure 2 As shown, the display module 100 also includes a pixel definition layer 210, which is disposed on the substrate 110 and arranged around the light-emitting layer 120; wherein, when the shielding layer 134 and the first electrode layer 136 are arranged on the same layer, the pixel definition layer 210 is filled between the first electrode layer 136 and the shielding layer 134; wherein, when the shielding layer 134 and the second electrode layer 132 are arranged on the same layer, the pixel definition layer 210 is filled between the second electrode layer 132 and the shielding layer 134.

[0039] In this embodiment, the display module 100 further includes a pixel definition layer 210, which is disposed on the substrate 110 and arranged around the light-emitting layer 120 to determine the position and size of the pixels, separate the pixels, and prevent color crosstalk between pixels. When the shielding layer 134 and the first electrode layer 136 are arranged in the same layer, the pixel definition layer 210 is filled between the first electrode layer 136 and the shielding layer 134. When the shielding layer 134 and the second electrode layer 132 are arranged in the same layer, the pixel definition layer 210 is filled between the second electrode layer 132 and the shielding layer 134, so that the first electrode layer 136 and the second electrode layer 132 and the shielding layer 134 are isolated. This improves the stability of the display module 100 during operation.

[0040] Specifically, when the shielding layer 134 and the first electrode layer 136 are arranged on the same layer, the material of the shielding layer 134 is the same as that of the first electrode layer 136. The first electrode layer 136 is the anode of the light-emitting layer. The material of the first electrode layer 136 is indium tin oxide (ITO). The material of the first electrode layer 136 is also indium tin oxide (ITO).

[0041] The material of the first electrode layer 136 may also be other metal materials or tin-doped indium oxide materials.

[0042] Specifically, when the shielding layer 134 and the second electrode layer 132 are arranged in the same layer, the material of the shielding layer 134 is the same as that of the second electrode layer 132 . The second electrode layer 132 is a cathode and the material of the second electrode layer 132 can be a metal alloy, such as magnesium-silver alloy (AgMg).

[0043] According to some embodiments of the present application, optionally, Figure 3 As shown, the shielding layer 134 is provided with a plurality of through holes 138 , and the plurality of through holes 138 are located in the bending region 116 .

[0044] In this embodiment, multiple through holes 138 are provided in the shielding layer 134, and the multiple through holes 138 are located in the bending area 116, so as to reduce the internal force generated by the display module 100 during the bending process, which may cause damage to the display module 100, such as cracks or display abnormalities.

[0045] Specifically, the bending area may be considered to have a through hole 138 with a diameter less than 5 um on the mask according to the minimum process capability to reduce the bending stress.

[0046] Specifically, the aperture of the through hole 138 may be 1 um, or 2.5 um, or 4 um.

[0047] According to some embodiments of the present application, optionally, the shielding layer 134 is grounded.

[0048] In this embodiment, the shielding layer 134 is grounded, and the electromagnetic cross-modulation interference between the antenna 250 and the display driving circuit 240 is reduced through the electromagnetic shielding principle, thereby improving the signal quality of the electronic device 220.

[0049] Specifically, the grounding line of the shielding layer 134 can be connected to the ground line (GND, Ground) of the panel or flexible printed circuit board 244 (FPC, flexible print circuit) using metal 2 routing (metal 2 routing is a metal routing on the same layer as the data driving line, generally titanium-aluminum-titanium alloy) or metal 1 routing (metal 1 routing, generally molybdenum metal).

[0050] Furthermore, by increasing the conductive area and grounding of the shielding layer 134 , when static electricity is generated, the static electricity is quickly discharged through the shielding layer 134 and grounded, thereby improving the reliability of electrostatic discharge (ESD) of the display module 100 .

[0051] According to some embodiments of the present application, optionally, the first electrode layer 136 is the anode of the light-emitting layer 120, the second electrode layer 132 is the cathode of the light-emitting layer 120, and the first electrode layer 136 and the second electrode layer 132 provide power to the light-emitting layer 120 so that the light-emitting layer 120 can emit light.

[0052] According to some embodiments of the present application, an electronic device 220 is provided, comprising a frame 230 and a display module 100 as in any of the above embodiments, wherein the display module 100 is disposed in the frame 230. Therefore, the electronic device 220 has all the beneficial effects of the display module 100 as in any of the above embodiments.

[0053] According to some embodiments of the present application, optionally, Figure 3 , Figure 4 and Figure 5As shown, the display module 100 includes a display portion 232 and a bending portion 234. The display portion 232 is provided with a light-emitting layer 120; the bending portion 234 is connected to the display portion 232 and is located on a side of the display portion 232 close to the antenna 250 of the frame 230, the bending portion 234 is bent between the display portion 232 and the frame 230, and the shielding layer 134 is provided on the bending portion 234.

[0054] In this embodiment, the display module 100 includes a display portion 232 and a bending portion 234. The display portion 232 is provided with a light-emitting layer 120. The bending portion 234 is connected to the display portion 232 and is located on a side of the display portion 232 close to the antenna 250. The bending portion 234 is bent between the display portion 232 and the frame 230, and the shielding layer 134 is provided at the bending portion 234. Through the electromagnetic shielding principle, the electromagnetic intermodulation interference between the antenna 250 and the display driving circuit 240 is reduced, and the signal quality of the electronic device 220 is improved.

[0055] Specifically, a shielding film is attached to the lower frame area of ​​the display panel to reduce the electromagnetic interference of the antenna 250. If it is an OLED display screen, the shielding layer 134 is set at the bending part 234, and the signal quality improvement effect is particularly obvious.

[0056] According to some embodiments of the present application, optionally, Figure 3 As shown, the electronic device 220 further includes a display driving circuit 240 , which is electrically connected to the display module 100 for driving the display module 100 ; the shielding layer 134 is located between the display driving circuit 240 and the antenna 250 .

[0057] In this embodiment, the electronic device 220 further includes a display driving circuit 240, which is electrically connected to the display module 100 and is used to drive the display module 100. The shielding layer 134 is located between the display driving circuit 240 and the antenna 250, and the electromagnetic shielding principle is used to reduce the electromagnetic intermodulation interference between the antenna 250 and the driving circuit, thereby improving the signal quality of the electronic device 220 and enhancing the user experience.

[0058] Further, the display module 100 is electrically connected to the display driver circuit 240, wherein the display driver circuit 240 is a display driver integrated circuit (Driver IC). The display driver circuit 240 and the antenna 250 are shielded by the shielding layer 134. The display driver circuit 240 is electrically connected to a flexible printed circuit board 244 (FPC, flexible print circuit), and a touch integrated circuit 242 (Touch IC, Touch IC) is provided on the flexible printed circuit board 244. The display module 100 uses a polyimide substrate 246 (PI sub, Polyimide substrate). The shielding layer 134 is located between the display driver circuit 240 and the antenna 250, and the electromagnetic shielding principle is used to reduce the electromagnetic intermodulation interference between the antenna 250 and the driver circuit, improve the signal quality of the electronic device 220, and thus enhance the user experience.

[0059] According to some embodiments of the present application, if the electronic device 220 adopts the general packaging technology of the liquid crystal display (LCD), the narrow frame uses chip on glass (COG) bonding, and it is necessary to compress the design routing (through a variety of routing technologies, such as double-sided routing, narrower routing, etc.), so that the overall layout of the fanout (Fanout) and the multiplexer (Demux) is shortened along the length of the long axis direction of the display module 100, so that the display driver integrated circuit (DDIC) and the fanout and Demux layout are closer to the bottom frame of the electronic device 220. The reduction of the bottom frame area causes the compressed Fanout and Demux to be closer to the antenna 250 under the middle frame, which is easy to cause electromagnetic interference, weaken the antenna 250 signal, and affect reliability and user experience.

[0060] If the electronic device 220 adopts DDIC packaging technology, DDIC is bonded on a flexible film to achieve bending, which is widely used in LCD or rigid OLED display screens. However, the main interference source of Chip On Film (COF) packaging technology is caused by the source drive signal line. As long as there is an image display, there will be a large number of source drive line (source) signal flips. When making a call, the RF signal emitted by the antenna 250 is easy to couple with the source drive line (source) drive array signal, thereby affecting the call quality.

[0061] If the electronic device 220 adopts DDIC packaging technology, DDIC bonding is applied to the flexible PI substrate, which is widely used in flexible OLED. However, the main interference source of chip packaging on plastic substrate technology (COP, chip on plastic) is caused by the source drive signal line. As long as there is an image display, there will be a large number of source drive line (source) signal flips. When making a call, the RF signal emitted by the antenna 250 is easy to couple with the source drive line drive array signal, thereby affecting the call quality.

[0062] Therefore, the electronic device 220 of the present application is set on the same layer through the shielding layer 134 and the second electrode layer 132 of the light-emitting layer 120. When manufacturing the display module 100, the shielding layer 134 is directly designed into the second electrode layer 132 of the display module 100, and the shielding layer 134 of the corresponding area is manufactured using the second electrode layer 132. The manufacturing is completed by integration, and the shielding layer 134 is embedded in the display module 100. There is no need to increase additional costs and manufacturing processes, and the number of layers of the display module 100 will not increase due to the addition of the shielding layer 134. The structure and manufacturing process of the display module 100 are simplified, and the production efficiency of the product is improved. At the same time, through the principle of electromagnetic shielding, the shielding layer 134 reduces the electromagnetic intermodulation interference between the antenna 250 and the display drive circuit 240, and improves the signal quality of the electronic device 220.

[0063] Specifically, the electronic device 220 defined in the present application may be a mobile phone, a tablet computer, an electronic notebook, a car-mounted tablet computer, or the like.

[0064] The display module 100 is an OLED display screen.
