[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings 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 making creative work are within the scope of protection of this application.

[0023] like Figures 1 to 3 As shown, an embodiment of the present application provides a display module, including a display panel 1, a supporting component 2, a mainboard 3 and a transparent conductive film 4.

[0024] The display panel 1 has a light-transmitting area AA, and the display panel 1 may be an OLED display panel or a liquid crystal display panel. For ease of description, the embodiment of the present application is described by taking the display panel 1 as an OLED display panel as an example.

[0025] The support assembly 2 is located at the backlight side of the display panel 1 , and the support assembly 2 is provided with light-transmitting holes 20 corresponding to the light-transmitting areas AA.

[0026] The main board 3 is located at the backlight side of the display panel 1 . A photosensitive element 30 corresponding to the light-transmitting hole 20 is disposed on the main board 3 . The photosensitive element 30 is used to sense the intensity of light entering from the light-transmitting hole 20 .

[0027] The transparent conductive film 4 is disposed between the light-transmitting hole 20 and the photosensitive element 30 . The transparent conductive film 4 is grounded to discharge the radiated electromagnetic waves generated by the display panel 1 when working to the ground.

[0028] The photosensitive element 30 is a device used by the display module to sense the intensity of external light, and is used to adjust the brightness of the display panel 1: when the external light is strong, the brightness of the display panel 1 increases; when the external light is weak, the brightness of the display panel 1 decreases. While saving power consumption, the brightness of the display panel 1 is made more suitable for the human eye. Since the photosensitive element 30 needs to measure external light, it is generally installed outside the display panel 1 (generally at the frame position) to sense external light. However, for high-end display modules, the screen-to-body ratio requirements are very high. It is usually necessary to place the photosensitive element 30 on the backlight side of the display panel 1 (called under-screen light sensing) without occupying the frame space to increase the screen-to-body ratio.

[0029] The support component 2 is located on the backlight side of the display panel 1. The support component 2 is provided with a light-transmitting hole 20 corresponding to the light-transmitting area AA, so that external light enters the under-screen photosensitive element 30 through the light-transmitting hole 20. The photosensitive element 30 measures the intensity of the penetrating light, thereby adjusting the brightness of the display panel 1.

[0030] The OLED display panel 1 generates radiated electromagnetic waves when working. Considering that the OLED display panel 1 has a certain transmittance (2%-4%), the effective electrical signal strength generated by the light entering the photosensitive element 30 is reduced. Even if the light-sensing output signal after the mixed interference signal is subjected to multiple filtering processes, the effect is still not ideal, and the light-sensing value is inaccurate, resulting in the display panel 1 having a flickering display problem.

[0031] To this end, the present application performs shielding processing at the interference source, reduces the interference signal, improves the signal-to-noise ratio of the photosensitive element, and solves the problem of the display panel flickering.

[0032] Specifically, a transparent conductive film 4 is arranged between the light-transmitting hole 20 of the support assembly 2 and the photosensitive element 30, and the transparent conductive film 4 is grounded to discharge the radiated electromagnetic waves generated by the display panel 1 when working to the ground. Since the transparent conductive film 4 can transmit light and will not affect the light path, it can shield the radiated electromagnetic waves and discharge the radiated electromagnetic waves to the ground through the grounding setting. Therefore, the present application is based on the fact that the radiation interference of the display panel 1 with low light transmittance to the light perception under the screen is an important reason for the insufficient light perception accuracy. Shielding is performed from the interference source, and the transparent conductive film 4 is arranged between the light-transmitting hole 20 and the photosensitive element 30 and grounded, thereby reducing the interference signal and improving the signal-to-noise ratio and measurement accuracy of the photosensitive element.

[0033] Furthermore, the material of the transparent conductive film 4 is indium tin oxide (ITO for short), the light transmittance of the transparent conductive film 4 is greater than 90%, and the square resistance is 5 ohms. "Light transmittance greater than 90%" means that the transmittance from visible light to infrared light (wavelength 400nm-1300nm) is greater than 90%, so as to improve the light transmittance of the display panel 1.

[0034] In one example, a grounding wire is provided on the mainboard 2, and the transparent conductive film 4 is electrically connected to the grounding wire, so that the radiated electromagnetic waves generated by the display panel 1 during operation can be discharged to the ground.

[0035] In one example, the display panel 1 further includes a middle frame, which is disposed between the outer peripheral side of the display panel 1 and the main board 2, and includes a metal grounding portion 22, and the transparent conductive film 4 is electrically connected to the metal grounding portion 22. The middle frame may be a metal structural member, or may be a plastic member including a metal grounding portion, so that the transparent conductive film 4 is electrically connected to the middle frame or a part of the middle frame, so that the radiated electromagnetic waves generated by the display panel 1 during operation can be discharged to the ground.

[0036] In one example, the transparent conductive film 4 is disposed on the side of the photosensitive element 30 facing the display panel 1. The transparent conductive film 4 covers the photosensitive element 30, so that the transparent conductive film 4 is in close contact with the photosensitive element 30, thereby improving the sensitivity of the photosensitive element 30 and its optical path system. At this time, the transparent conductive film 4 can be electrically connected to the grounding wire provided on the mainboard 2, or the transparent conductive film 4 is electrically connected to the metal grounding part of the middle frame, so as to block the interference electromagnetic wave signal and discharge the radiated electromagnetic wave generated by the display panel 1 when working to the ground.

[0037] In one example, the support component 2 includes a support frame and a buffer layer, the buffer layer is located between the support frame and the display panel 1, a metal grounding portion 22 is provided on the backlight side of the display panel 1, the buffer layer exposes the metal grounding portion 22, the light-transmitting hole 20 passes through the metal grounding portion 22, and the transparent conductive film 4 is provided on the side of the metal grounding portion 22 away from the display panel 1, and the transparent conductive film 4 is electrically connected to the metal grounding portion 22, thereby blocking interference electromagnetic wave signals and discharging the radiated electromagnetic waves generated by the display panel 1 when working to the ground.

[0038] Optionally, the buffer layer is foam. Optionally, the transparent conductive film 4 is attached to the metal grounding portion 22 of the buffer layer by means of a conductive double-sided adhesive tape, completely covers the light-transmitting hole 20, and is electrically connected to the metal grounding portion 22. In one example, the transparent conductive film 4 is disposed on the side of the photosensitive element 30 facing the display panel 1, and is electrically connected to the metal grounding portion 22 of the buffer layer, so as to block the interfering electromagnetic wave signal and discharge the radiated electromagnetic wave generated by the display panel 1 when working to the ground.

[0039] Optionally, the metal grounding portion 22 and the grounding wire are generally made of copper, stainless steel, titanium alloy, etc., which are connected to the ground to provide electromagnetic protection for the display panel 1 and shield electromagnetic interference signals from the mainboard 2.

[0040] Furthermore, if Figure 4 As shown, the display panel 1 includes: a base substrate 11 , a drive array layer 12 , a pixel defining layer 13 , a light emitting functional layer 14 and an encapsulation layer 15 .

[0041] The material of the base substrate 11 may be glass or polyimide. When the material of the base substrate 11 is polyimide, the display panel may be a flexible foldable display panel.

[0042] The driving array layer 12 is located on the base substrate 11 and includes pixel circuits and signal lines, etc. The pixel defining layer 13 is located on the side of the driving array layer 12 away from the base substrate 11 and includes a plurality of pixel openings.

[0043] The light-emitting functional layer 14 is located on the side of the driving array layer 12 away from the base substrate 11 . The light-emitting functional layer 14 includes a plurality of light-emitting elements, at least part of which is located in the pixel opening. The encapsulation layer 15 is located on the side of the light-emitting element layer away from the base substrate 11 .

[0044] The encapsulation layer (Encapsulation) 15 includes a first inorganic layer, an organic layer and a second inorganic layer arranged in sequence in a direction away from the base substrate 11. Among them, the first inorganic layer and the second inorganic layer are both transparent inorganic film layers, and their materials may include one or more of the following materials: Al2O3, TiO2, ZrO2, MgO, HFO2, Ta2O5, Si3N4, AlN, SiN, SiNO, SiO, SiO2, SiC, SiCNx, ITO, IZO. These inorganic materials have both good light transmittance and good water and oxygen barrier properties. The material of the organic layer is a transparent organic conductive resin, specifically including a transparent matrix resin, and conductive molecules and / or conductive ions. Specifically, it can be a transparent conductive resin formed by stirring and completely dissolving organic acid-doped polyaniline, cross-linking monomers, toluene, etc.; or, conductive molecules such as polyaniline are added to the above transparent conductive resin; or, conductive ions are added to the above transparent conductive resin, such as nano-scale antimony-doped SiO2, and nano-scale conductive ions such as nano-scale indium tin oxide or nano-silver can also be used.

[0045] The first inorganic layer and the second inorganic layer made of inorganic materials completely cover the light-emitting functional layer 14, which can prevent water vapor from invading from the side and affecting the electrical performance of the light-emitting functional layer 14. The patterned organic layer has high elasticity and is sandwiched between the first inorganic layer and the second inorganic layer. It can not only inhibit the cracking of the inorganic film and release the stress between the inorganic materials, but also improve the flexibility of the entire encapsulation layer, thereby achieving reliable flexible encapsulation.

[0046] In some embodiments, the display panel 1 includes: a polarizer layer 17 , a touch layer 18 and a transparent cover plate 19 .

[0047] like Figure 4As shown, the polarizer layer 17 is used to control the polarization direction of the light beam, and the touch layer 18 includes a plurality of touch electrodes, which can be capacitive touch electrodes, including self-capacitance and mutual capacitance. The working principle of the touch layer 18 is as follows: when a finger approaches or touches the plane where the plurality of touch electrodes are located, the finger is equivalent to a conductor, and the capacitance of the finger will be superimposed on the capacitance of the touch layer 18, so that the capacitance of the touch layer 18 increases. During touch detection, the touch layer 18 detects the plurality of touch electrodes in turn, and determines the coordinates X in the horizontal direction and Y in the vertical direction according to the changes in capacitance before and after the touch, and then combines them into the touch coordinates of the plane, which is equivalent to projecting the touch points on the touch layer 18 to the X-axis and Y-axis directions, and then calculating the coordinates in the X-axis and Y-axis directions, and finally combining them into the coordinates of the touch points.

[0048] The transparent cover plate 19 is bonded to the touch layer 18 by transparent optical adhesive, so as to protect the internal structure of the display panel 1 and prevent foreign matter from entering or scratching the touch layer 18 .

[0049] At present, most foldable display panels 1 use traditional polarizer technology. Since the polarizer layer 17 is relatively thick, creases are easily generated after bending. Therefore, a color filter on Encapsulation (COE) can be used instead of the polarizer layer to eliminate creases, and the total cost is expected to decrease. However, the light transmittance of the OLED display panel 1 using COE technology is greatly reduced, only 0.5% or even lower, resulting in external light passing through the display panel 1. It will be submerged in the interference signal of the radiated electromagnetic wave 10, and the light intensity entering the photosensitive element 30 under the screen will be greatly reduced, resulting in large and inaccurate light measurement errors, poor display effects and other problems.

[0050] To this end, in some embodiments, the display panel 1 includes: a color resist layer 16 , a touch layer 18 and a transparent cover plate 19 .

[0051] like Figure 5 As shown, the color resist layer 16 is located on the side of the encapsulation layer 15 away from the base substrate 11, and the color resist layer 16 includes a plurality of color resist units and light resists located between adjacent color resist units, and the color resist units are arranged corresponding to the light emitting elements. The touch layer 18 is located between the encapsulation layer 15 and the color resist layer 16, and the transparent cover 19 covers the color resist layer 16.

[0052] The color blocking layer 16 is composed of red, green and blue primary color transparent films arranged in a pixel matrix according to the light-emitting elements of the display panel 1, overlapping with the matrix of the red, green and blue primary color light-emitting elements, so that the display panel 1 emits three primary color light while maximally preventing external light from entering the display module. Therefore, the color blocking layer 16 plays a role similar to the polarizer layer 17 in eliminating external reflected light.

[0053] The touch layer 18 is located between the encapsulation layer 15 and the color resist layer 16 , and the transparent cover plate 19 covers the color resist layer 16 , which will not be described in detail.

[0054] The display module provided in the embodiment of the present application is particularly suitable for mobile terminals such as low-transmittance folding screens or straight-screen mobile phones that adopt COE technology. By setting the transparent conductive film 4 between the light-transmitting hole 20 of the supporting component 2 and the photosensitive element 30 and grounding it, and replacing the polarizer layer 17 with a color resist layer 16, it can avoid the problem of creases caused by bending due to the thick polarizer layer 17, and can also reduce the radiation interference signal received by the photosensitive element 30, thereby improving the signal-to-noise ratio and measurement accuracy of the photosensitive element 30, and enhancing the user experience.

[0055] The shielding effect of the transparent conductive film 4 is compared with two groups of test samples, each group has 3 test samples. Table 1 shows the light perception test data without the transparent conductive film 4, the signal-to-noise ratio is close to 1 (the signal is submerged in the noise and cannot be extracted), which is very poor and cannot be used; Table 2 shows the light perception test data after adding the transparent conductive film 4, the signal-to-noise ratio is greatly improved by more than 4 times, reaching a usable level.

[0059]

[0060] The present application is based on the fact that the radiation interference of the low-transmittance display panel to the light perception under the screen is an important reason for the insufficient light perception accuracy. Shielding is performed from the interference source, and a transparent conductive film is set between the light-transmitting hole of the support component and the photosensitive element and grounded, which can reduce the interference signal, improve the signal-to-noise ratio of the photosensitive element, and solve the display problem of the display panel flickering. In addition, the display module of the present application can also be combined with the processor for further filtering and other optimizations to obtain accurate external light intensity and stably control the brightness of the display panel 1.

[0061] In addition, the present application also provides an electronic device, including the display module as described above. The electronic device can be, for example but not limited to, a mobile phone, a tablet computer, a wearable device, a television, a display, a laptop computer, an e-book, an e-newspaper, a digital photo frame, a navigator, or any other product or component with a display function.

[0062] It should be easily understood that “on,” “above,” and “over” in this application should be interpreted in the broadest manner, so that “on” not only means “directly on something,” but also includes the meaning of “on something” with intervening features or layers therebetween, and “above” or “over” not only includes the meaning of “above something” or “over,” but also may include the meaning of “above something” or “over” with no intervening features or layers therebetween (i.e., directly on something).

[0063] The term "substrate substrate" as used herein refers to the material on which subsequent material layers are added. The substrate substrate itself can be patterned. The material added on top of the substrate substrate can be patterned, or can remain unpatterned. In addition, the substrate substrate can include a wide range of materials, such as silicon, germanium, gallium arsenide, indium phosphide, etc. Alternatively, the substrate substrate can be made of a non-conductive material (e.g., glass, plastic, or sapphire wafer, etc.).

[0064] The term "layer" used in the text may refer to a material portion including an area with a certain thickness. A layer may extend over the entire underlying structure or overlying structure, or may have a range smaller than the range of the underlying or overlying structure. In addition, a layer may be an area of ​​a homogeneous or inhomogeneous continuous structure, the thickness of which is less than the thickness of the continuous structure. For example, a layer may be located between the top surface and the bottom surface of the continuous structure or between any paired lateral planes at the top surface and the bottom surface. A layer may extend laterally, vertically and / or along a tapered surface. A substrate substrate may be a layer, may include one or more layers therein, and / or may have one or more layers located thereon, above it and / or below it. A layer may include multiple layers. For example, an interconnect layer may include one or more conductors and a contact layer (forming contacts, interconnects and / or vias therein) and one or more dielectric layers.
