Display modules and electronic devices

[0001] Cross-reference to related applications

[0002] This application claims priority to Chinese Patent Application No. 202411804197.4, filed on December 10, 2024, entitled “Display Module and Electronic Device”, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application belongs to the field of electronic equipment technology, specifically relating to a display module and an electronic device. Background Technology

[0004] In related technologies, antennas are designed at the top and bottom of the mid-frame of electronic devices. With the development of full-screen technology, the display module driver chip and related driving circuits, thin film transistors (TFTs) are getting closer and closer to the edge of the display module. This means that the distance between the display module driver circuit and the driver integrated circuit (IC) and the mid-frame antenna is greatly shortened, resulting in greater electromagnetic interference between the antenna and the display module.

[0005] Currently, to reduce electromagnetic interference from the display module to the antenna, an electrostatic shielding layer is installed on the display module. This electrostatic shielding layer can reduce electromagnetic interference from the display module to the antenna. However, the added shielding layer makes the original display module structure more complex and increases the manufacturing difficulty of the display module. Summary of the Invention

[0006] This application aims to provide a display module and electronic device that at least solves one of the problems of complex display module structure.

[0007] In a first aspect, this application proposes a display module, including a substrate, a first electrode layer, a light-emitting layer, a second electrode layer, and a shielding layer. The substrate has a first region and a second region; the first electrode layer is disposed on the substrate and located in the first region; the light-emitting layer is disposed on the first electrode layer, electrically connected to the first electrode layer, and located in the first region; the second electrode layer is disposed on the light-emitting layer, electrically connected to the light-emitting layer, and located in the first region; the shielding layer is arranged in the same layer as the first electrode layer or the second electrode layer, covering at least a portion of the second region.

[0008] This application proposes a display module including a substrate and a light-emitting layer. The substrate is divided into two regions, a first region and a second region. The light-emitting layer is located in the first region and is used to display images and provide illumination. A first electrode layer is disposed on the substrate in the first region, and the light-emitting layer is disposed on and electrically connected to the first electrode layer. A second electrode layer is disposed on and electrically connected to the light-emitting layer. The first and second electrode layers are used to conduct current and ensure circuit continuity. A shielding layer is arranged in the same layer as either the first or second electrode layer. Both the first and second electrode layers are electrically connected to the light-emitting layer and serve as the cathode and anode of the light-emitting layer. By using a shielding layer, this application reduces electromagnetic intermodulation interference (EMI) between the display module and the antenna transmit and receive (TRX), improves the antenna signal-to-noise ratio, reduces the risk of antenna interference to the display module, improves the reliability of the display module, and enhances the stability of the antenna signal, thereby improving the user experience. Meanwhile, this application places the shielding layer and the first electrode layer or the second electrode layer on the same layer. When manufacturing the display module, the shielding layer is designed to be on the same layer as the first electrode layer or the second electrode layer. The shielding layer in the corresponding area is manufactured using the first electrode layer or the second electrode layer. The manufacturing is completed in one piece. The shielding layer is embedded in the display module without adding extra costs and manufacturing processes. It also does not increase the number of layers in the display module due to the addition of the shielding layer. This simplifies the structure and manufacturing process of the display module and improves the production efficiency of the product.

[0021] A display module 100 and an electronic device 220 according to an embodiment of this application are described below with reference to Figures 1 to 5.

[0022] This application provides a display module 100, as shown in Figures 1 and 2. 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, covering at least a portion of the second region 114.

[0023] This application discloses 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 120 is located in the first region 112 and is used to display images and provide illumination. A 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 electrically connected to the first electrode layer 136. A second electrode layer 132 is disposed on the light-emitting layer 120 and electrically connected to the light-emitting layer 120. The first electrode layer 136 and the second electrode layer 132 are used to conduct current and ensure circuit continuity. A 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 serve as the cathode and anode of the light-emitting layer 120. This application reduces electromagnetic intermodulation interference between the display module 100 and the antenna 250's transmission and reception (TRX) by setting the shielding layer 134, improves the signal-to-noise ratio of the antenna 250, reduces the risk of interference to the display module 100 from 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. Meanwhile, this application places 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 on the same layer as the first electrode layer 136 or the second electrode layer 132. 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 in one piece. The shielding layer 134 is embedded in the display module 100 without adding extra costs and manufacturing processes. The number of layers in the display module 100 will not increase due to the addition of the shielding layer 134. This simplifies the structure and manufacturing process of the display module 100 and improves the production efficiency of the product.

[0024] Specifically, by providing a shielding layer 134 in the second region 114 of the display module 100, electromagnetic interference from the antenna 250 can be reduced. If it is an Organic Light-Emitting Diode (OLED) display, the shielding layer 134 covers at least a portion of the second region 114, resulting in a particularly significant improvement in electromagnetic interference. This application directly designs the shielding layer 134 into the first electrode layer 136 or the second electrode layer 132 of the OLED luminescent material, using the first electrode layer 136 or the second electrode layer 132 to manufacture the corresponding region's shielding layer 134. This integrated manufacturing process embeds the shielding layer into the Liquid Crystal Multiple (LCM) display module without increasing costs, making the product more competitive in the market.

[0025] Meanwhile, by using the first electrode layer 136 or the second electrode layer 132 to manufacture the corresponding area of ​​the shielding layer 134, the manufacturing is completed in one piece, without increasing the manufacturing cost of the product. This ensures that users do not have to spend extra money when repairing or replacing the product later, thus providing after-sales service for the product.

[0026] Meanwhile, by using the first electrode layer 136 or the second electrode layer 132 to manufacture the corresponding area of ​​the shielding layer 134, the manufacturing is completed in one piece. The number of layers of the display module 100 is not increased due to the addition of the shielding layer 134, thus ensuring the thickness of the electronic device 220 and enhancing the market competitiveness of the product.

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

[0028] According to some embodiments of this application, optionally, as shown in FIG1, FIG2 and FIG3, the bending region 116 is a part 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 portion of the second region 114, and the shielding layer 134 covers the bending region 116. Since the bending region 116 is closer to the antenna 250, placing the shielding layer 134 in the bending region 116 can further reduce the interference of the display module 100 on the antenna 250.

[0030] According to some embodiments of this application, optionally, as shown in FIG3, the shielding layer 134 extends into the area of ​​the second region 114 other than the bending region 116.

[0031] In this embodiment, the shielding layer 134 extends into the second region 114, excluding the bending region 116. If the film layers with varying thicknesses are only manufactured in a fixed small area, stress is easily generated, and it is impossible to create a transition zone in the process. Extending the shielding layer 134 into the inactive display (Active Area, AA) region, while controlling the film thickness, helps improve reliability after bending. Here, the AA region refers to the operable area of ​​the thin-film transistor (TFT) liquid crystal screen, that is, the touchable area.

[0032] Specifically, the display module 100 is an Organic Light-Emitting Diode (OLED) module. This application provides a shielding layer 134 over the entire area corresponding to the OLED module. This shielding layer 134 uses indium tin oxide (ITO), tin-doped indium oxide, or magnesium-silver alloy (AgMg), covering the bending area 116 of the display module 100 to the flexible printed circuit board (FPC) bonding area, and is connected to the zero-potential reference level of the panel, forming a grounded shield. Through electromagnetic shielding, electromagnetic intermodulation interference between the antenna 250 and the display driving circuit 240 is reduced, improving the signal quality of the electronic device 220.

[0033] Furthermore, this application utilizes the fundamental principle of adding a shielding layer 134 to create an electromagnetic barrier. Based on existing OLED film layer processing methods and material characteristics, the conductive layer is mainly a metal alloy layer (cathode) or ITO (anode) and other metal traces. For example, metal 1 / metal 2 are molybdenum (Mo) and titanium-aluminium-titanium (TiAlTi), respectively. Therefore, this application's embodiments, through conventional isolation design, replace the use of an open mask as the cathode with a new mask design, forming a shielding layer 134 for the integrated circuit (IC), bending area, and the entire lower bezel area. Alternatively, when making the anode contact layer ITO, the same mask design can be used, adopting a shielding layer 134 design corresponding to the lower bezel. During film layer manufacturing, the complete shielding layer 134 can be integrally formed without additional cost or manufacturing process.

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

[0035] In this embodiment, the substrate 110 includes a substrate 140, a buffer layer 150, a first doped layer 160, a second doped layer 170, an insulating layer 180, a planarization layer 190, and a driver 200. The buffer layer 150 is disposed on the substrate 140, which serves as the basic component of the display module 100, providing support for other functional layers. The substrate 140 also helps control pixel arrangement and prevents leakage. The buffer layer 150 reduces damage to the display module 100 from external impacts and also provides planarization and isolation. The first doped layer 160 is disposed on the side of the buffer layer 150 away from the substrate 140, and the second doped layer 170 is disposed on the same side of the buffer layer 150 away from the substrate 140, arranged side-by-side with the first doped layer 160. The first doped layer 160 is either an N-type or P-type doped layer, and the second doped layer 170 is another type of the first doped layer 160. The N-type and P-type doped layers facilitate charge transfer and play a crucial role in the light-emitting function of the display module 100. An insulating layer 180 is disposed on the side of the first doped layer 160 and the second doped layer 170 away from the substrate 140. The first doped layer 160 and the second doped layer 170 can form a PN junction for conductivity, while the insulating layer 180 primarily prevents current from flowing in unwanted areas, providing electrical isolation and protection. A planarization 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 planarization layer 190 away from the substrate 140. The planarization layer 190 makes the surface of the display module 100 smoother and provides a good adhesion base for subsequent functional layers, thus improving the display effect. The driver 200 is disposed on the insulating layer 180 and the planarization 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. It is used to precisely control the current of each pixel and improve the imaging quality of the display module 100.

[0036] Furthermore, a gate 172, a drain 174, and a source 176 are also provided in the insulating layer 180. The gate 172 is a component of the thin-film transistor and is used to control the switching of the pixel circuit, thereby enabling the display module 100 to accurately display images. In the field-effect transistor of the electronic device, the drain 174 is the end from which current flows out, and the source 176 is the end from which 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 doped layer 160 and the second doped layer 170.

[0038] According to some embodiments of this application, optionally, as shown in FIG1 and FIG2, 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; wherein, when the shielding layer 134 is arranged in the same layer as the first electrode layer 136, the pixel definition layer 210 fills the space between the first electrode layer 136 and the shielding layer 134; when the shielding layer 134 is arranged in the same layer as the second electrode layer 132, the pixel definition layer 210 fills the space 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. The pixel definition layer 210 determines the position and size of the pixels, separates the pixels, and prevents color mixing between pixels. When the shielding layer 134 is arranged on the same layer as the first electrode layer 136, the pixel definition layer 210 fills the space between the first electrode layer 136 and the shielding layer 134. When the shielding layer 134 is arranged on the same layer as the second electrode layer 132, the pixel definition layer 210 fills the space between the second electrode layer 132 and the shielding layer 134, thus isolating the first electrode layer 136, the second electrode layer 132, and the shielding layer 134. 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 in 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, and the material of the first electrode layer 136 is indium tin oxide (ITO).

[0041] The material of the first electrode layer 136 can 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 the 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 this application, optionally, as shown in FIG3, 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, by providing multiple through holes 138 in the shielding layer 134, and the multiple through holes 138 being located in the bending area 116, the internal forces generated by the display module 100 during the bending process are reduced, which may cause damage to the display module 100, such as cracks or display abnormalities.

[0045] Specifically, in the bending area, the diameter of the through hole 138 on the mask can be less than 5um to reduce bending stress, based on the minimum process capability.

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

[0047] According to some embodiments of this application, the shielding layer 134 may optionally be grounded.

[0048] In this embodiment, the shielding layer 134 is grounded, and the electromagnetic intermodulation interference between the antenna 250 and the display driving circuit 240 is reduced by 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) of the panel or flexible printed circuit board 244 using either a metal 2 trace (metal 2 trace is a metal trace used on the same layer as the data drive line, usually titanium-aluminum-titanium alloy) or a metal 1 trace (metal 1 trace, usually molybdenum metal).

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

[0051] According to some embodiments of this 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 supply power to the light-emitting layer 120 so that the light-emitting layer 120 can emit light.

[0052] According to some embodiments of this application, an electronic device 220 is proposed, including a frame 230 and a display module 100 as described in any of the above embodiments, wherein the display module 100 is disposed in the frame 230. Therefore, the electronic device 220 possesses all the beneficial effects of the display module 100 as described in any of the above embodiments.

[0053] Optionally, according to some embodiments of this application, as shown in Figures 3, 4, and 5, the display module 100 includes a display section 232 and a bent section 234. The display section 232 is provided with a light-emitting layer 120; the bent section 234 is connected to the display section 232 and is located on the side of the display section 232 near the antenna 250 of the frame 230. The bent section 234 bends between the display section 232 and the frame 230, and a shielding layer 134 is disposed on the bent section 234.

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

[0055] Specifically, applying a shielding film to the lower bezel area of ​​the display panel can reduce electromagnetic interference from the antenna 250. For OLED displays, the shielding layer 134 is placed at the bend 234, which significantly improves signal quality.

[0056] According to some embodiments of this application, optionally, as shown in FIG3, 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.

[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. A shielding layer 134 is located between the display driving circuit 240 and the antenna 250. Utilizing the principle of electromagnetic shielding, the electromagnetic intermodulation interference between the antenna 250 and the driving circuit is reduced, improving the signal quality of the electronic device 220 and thus enhancing the user experience.

[0058] Furthermore, the display module 100 is electrically connected to the display driving circuit 240, which is a display driver integrated circuit (Driver IC). A shielding layer 134 shields the display driving circuit 240 and the antenna 250. The display driving circuit 240 is electrically connected to a flexible printed circuit board (FPC) 244, on which a touch integrated circuit 242 (Touch IC) is disposed. The display module 100 uses a polyimide substrate 246 (PI sub). The shielding layer 134, located between the display driving circuit 240 and the antenna 250, utilizes electromagnetic shielding principles to reduce electromagnetic intermodulation interference between the antenna 250 and the driving circuit, improving the signal quality of the electronic device 220 and thus enhancing the user experience.

[0059] According to some embodiments of this application, if the electronic device 220 adopts the general packaging technology of Liquid Crystal Display (LCD), and the narrow bezel uses Chip On Glass (COG) bonding, it is necessary to compress the design traces (through various trace techniques, such as double-sided traces, narrower traces, etc.) to shorten the overall layout of the fanout and demux along the long axis of the display module 100, making the display driver integrated circuit (DDIC) and the fanout and demux layout closer to the bottom bezel of the electronic device 220. Reducing the bottom bezel area results in the compressed fanout and demux being closer to the antenna 250 under the middle frame, which can easily cause electromagnetic interference, weakening the antenna 250 signal and affecting reliability and user experience.

[0060] If electronic device 220 uses DDIC packaging technology, bonding the DDIC onto a flexible film, it can be bent, and is widely used in LCD or rigid OLED displays. However, the main source of interference in Chip On Film (COF) packaging technology is the source drive signal lines. As long as there is an image display, there are a large number of source drive line (source) signal flips. During a call, the radio frequency signal emitted by antenna 250 is prone to coupling with the source drive line (source) drive array signal, thus affecting the call quality.

[0061] If electronic device 220 uses DDIC packaging technology, bonding the DDIC onto a flexible PI substrate, it is widely used in flexible OLEDs. However, the main source of interference in chip-on-plastic (COP) technology is the source drive signal lines. Whenever there is an image display, there are a large number of source drive line (source) signal flips. During a call, the radio frequency signal emitted by antenna 250 can easily couple with the source drive line drive array signal, thus affecting the call quality.

[0062] Therefore, in this application, the electronic device 220 has the shielding layer 134 and the second electrode layer 132 of the light-emitting layer 120 disposed on the same layer. When manufacturing the display module 100, the shielding layer 134 is directly designed into the second electrode layer 132 of the display module 100. The shielding layer 134 in the corresponding area is manufactured using the second electrode layer 132.
