The anode layer includes a plurality of transparent anodes, each transparent anode being connected to a sub-pixel. The driving circuit layer is provided with a plurality of first driving units in a region corresponding to the first pixel definition region. The first transparent conductive layer forms a plurality of curved transparent conductive lines, and each transparent anode is electrically connected to a first driving unit through a transparent conductive line. Based on this, in the display device of this application embodiment, when external light passes through the display device, a transparent anode is disposed in the anode layer corresponding to the first pixel definition area, and the transparent anode has less diffraction interference to the external light; and, the opaque first driving unit is disposed in the area outside the first pixel definition area, and the opaque first driving unit does not affect the incident external light at all, so that the transmittance of external light in the area corresponding to the first pixel definition area is high; at the same time, when external light passes through the circular or elliptical sub-pixels, the energy in the diffraction spectrum formed by the external light is more concentrated in the primary diffraction fringes, the energy of each secondary diffraction fringes is lower, and there are fewer secondary diffraction fringes, thereby reducing the diffraction phenomenon.

[0033] The following will refer to the appendices in the embodiments of this application. Figures 1 to 18The technical solutions in the embodiments of this application are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0034] This application provides an electronic device. The electronic device can be a mobile phone, tablet computer, or other motion terminal device; it can also be a gaming device, augmented reality (AR) device, virtual reality (VR) device, in-vehicle computer, laptop computer, data storage device, audio playback device, video playback device, wearable device, or any other device with a display device. Wearable devices can include smart bracelets, smart glasses, etc.

[0035] Please refer to Figure 1 , Figure 1 This is a schematic diagram of a first structure of an electronic device provided in an embodiment of this application. The electronic device 10 includes a cover plate 100, a display device 200, a middle frame 300, a circuit board 400, a battery 500, a back cover 600, and an image sensor 700.

[0036] Display device 200 can be used to display information such as images and text. Display device 200 can be an organic light-emitting diode (OLED) display device.

[0037] The cover plate 100 can be installed on the middle frame 300 and covers the display device 200 to protect it from scratches or water damage. The cover plate 100 can be a transparent glass cover plate, allowing the user to observe the content displayed on the display device 200 through it. The cover plate 100 can be made of sapphire glass.

[0038] The display device 200 can be mounted on the middle frame 300 and connected to the rear cover 600 through the middle frame 300 to form the display surface of the electronic device 10. The display device 200, as the front housing of the electronic device 10, together with the rear cover 600, forms the housing of the electronic device 10, used to house other electronic components of the electronic device 10. For example, the housing can be used to house electronic components such as the processor, memory, and one or more sensors of the electronic device 10.

[0039] The middle frame 300 can be a thin plate or sheet structure, or a hollow frame structure. The middle frame 300 provides support for electronic devices in the electronic device 10, allowing them to be mounted together. For example, electronic devices such as the image sensor 700, receiver, circuit board 400, and battery 500 in the electronic device 10 can be mounted on the middle frame 300 for fixation.

[0040] The circuit board 400 can be mounted on the mid-frame 300. The circuit board 400 can be the motherboard of the electronic device 10. The circuit board 400 can integrate one, two or more electronic devices such as a microphone, speaker, receiver, headphone jack, universal serial bus interface (USB interface), camera assembly, proximity sensor, environmental sensor, gyroscope and processor.

[0041] The display device 200 can be electrically connected to the circuit board 400, so that the processor on the circuit board 400 can control the display of the display device 200. An image sensor 700 can be disposed inside the display device 200. Both the display device 200 and the image sensor 700 can be electrically connected to the processor, and the image sensor 700 can acquire signals transmitted through the display device 200 to realize the corresponding functions of the image sensor 700.

[0042] For example, the image sensor 700 may be the front-facing camera module of the electronic device 10. When the processor receives a shooting command, the processor controls the front-facing camera module to capture images through the display device 200. When the processor does not receive a shooting command but receives an image display command, the processor controls the display device 200 to display the image.

[0043] The image sensor 700 may include a lens, a color filter, a light sensor, a digital-to-analog converter, and a digital processing chip. The lens may consist of multiple lenses. The lens can capture ambient light transmitted through the first display area 210. The color filter can decompose ambient light into monochromatic light such as red, blue, and green light. The light sensor is a semiconductor chip whose surface contains hundreds of thousands to millions of photodiodes. When the photodiodes are illuminated, they generate electrical charges. The light sensor can receive the filtered three-color ambient light and convert it into different electrical signals under the illumination of the three-color ambient light. The digital-to-analog converter can convert the electrical signals into digital image signals. The digital processing chip can process the digital image signals and obtain the final image information.

[0044] Understandably, after the light sensor collects the ambient light, the digital processing chip can process it through white balance, depigmentation, noise reduction, color gamut conversion, gamma correction, compression, etc., to obtain the final image information.

[0045] Battery 500 can be mounted on mid-frame 300. Simultaneously, battery 500 is electrically connected to circuit board 400 to power electronic device 10. Power management circuitry can be provided on circuit board 400. This power management circuitry distributes the voltage provided by battery 500 to various electronic components within electronic device 10. Battery 500 can be a rechargeable battery, such as a lithium-ion battery.

[0046] The back cover 600 can be located on the side of the circuit board 400 away from the display device 200, that is, the back cover 600 is located on the outermost side of the electronic device 10 and is used to form the outer contour of the electronic device 10. The back cover 600 can be integrally molded. During the molding process of the back cover 600, structures such as rear camera holes and fingerprint recognition module mounting holes can be formed on the back cover 600.

[0047] The back cover 600 can be made of metal, such as magnesium alloy or stainless steel. It should be noted that the material of the back cover 600 in this embodiment is not limited to these; other materials can also be used. For example, the back cover 600 can be made of plastic. Another example is that the back cover 600 can be made of ceramic or glass. Yet another example is that the back cover 600 can include both plastic and metal parts, and the back cover 600 can be a shell structure in which metal and plastic interact. Specifically, the metal part can be formed first, for example, by injection molding a magnesium alloy substrate, and then plastic can be injection molded onto the magnesium alloy substrate to form a plastic substrate, thus forming a complete shell structure.

[0048] Please combine Figure 1 And refer to Figure 2 , Figure 2 for Figure 1 The diagram shows a first structural schematic of the display device. The display device 200 may include a first display area 210 and a second display area 220 connected to each other. A cover plate 100 is disposed outside the first display area 210 and the second display area 220, covering the first display area 210 and the second display area 220. Electronic components such as a circuit board 400 and a battery 500 of the electronic device 10 may be disposed inside the first display area 210. That is, the circuit board 400, the battery 500, and other electronic components may be disposed between the first display area 210 and the back cover 600. An image sensor 700 may be disposed inside the first display area 210. The lens of the image sensor 700 may be positioned facing the first display area 210, and the image sensor 700 is used to acquire external light signals transmitted through the first display area 210 for imaging.

[0049] Both the first display area 210 and the second display area 220 can be used to display text or images. The first display area 210 and the second display area 220 can jointly display the same image; for example, the second display area 220 can display a portion of a preset image, while the first display area 210 displays the remaining portion of the preset image. Alternatively, the first display area 210 and the second display area 220 can display different images; for example, the second display area 220 can display a preset image, while the first display area 210 displays a taskbar image.

[0050] Understandably, the area of ​​the first display area 210 can be much smaller than that of the second display area 220. The second display area 220 can be positioned around the first display area 210, and the periphery of the first display area 210 can be adjacent to the second display area 220. The first display area 210 can be located in the middle of the second display area 220. Alternatively, the second display area 220 can partially surround the first display area 210, with some edges of the first display area 210 adjacent to the second display area 220. The corners of the second display area 220 can also be irregularly shaped, for example, having a notch, within which the first display area 210 can be located.

[0051] It is understood that the positional relationship between the first display area 210 and the second display area 220 is not limited to the example above, and other schemes that enable the display device 200 to include the first display area 210 and the second display area 220 are all within the scope of protection of this application.

[0052] It should be noted that, in this embodiment, the second display area 220 can serve as the main display area of ​​the display device 200, and the first display area 210 can serve as an auxiliary display area of ​​the display device 200. The second display area 220 can be an active-matrix OLED (AMOLED) display area, and the first display area 210 can be either an AMOLED or a passive-matrix OLED (PMOLED) display area. Although the display effect of PMOLED is lower than that of AMOLED, because the area of ​​the first display area 210 is very small, the content displayed is also small, and the first display area 210 is located at the edge of the display device 200, the importance of the displayed content is relatively low. Therefore, the first display area 210 can use PMOLED. The passively driven first display area 210 only requires one thin-film transistor (TFT) to drive it. The number of opaque thin-film transistors is extremely small, which can greatly improve the light transmittance of the first display area 210.

[0053] It should be understood that in the description of this application, terms such as "first" and "second" are used only to distinguish similar objects and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

[0054] Please see Figure 3 , Figure 3 forFigure 2 The diagram shows a first cross-sectional view of the display device along the direction from P1 to P2. The display device 200 may include a layered structure consisting of a driving circuit layer 291, a first transparent conductive layer 292, an anode layer 293, a pixel definition layer 294, a common electrode layer 295, etc., stacked sequentially.

[0055] The pixel definition layer 294 includes a first pixel definition region 2941, which can be configured to correspond to the first display area 210 of the display device 200. Please refer to... Figure 3 Please refer to point 4. Figure 4 for Figure 3 The diagram illustrates a structure of a pixel definition layer. A first pixel definition region 2941 has multiple pixel holes, each containing a pixel unit. Each pixel unit comprises an organic light-emitting material. The first pixel definition region 2941 may have at least one first pixel unit, which may include one or more sub-pixels 201. For example, a first pixel unit may include red, green, and blue sub-pixels. Sub-pixels 201 may be at least elliptical or circular sub-pixels, allowing the first pixel unit to contain either elliptical or circular sub-pixels.

[0056] An anode layer 293 can be stacked on one side of the pixel definition layer 294. The anode layer 293 is electrically connected to the driving circuit layer 291 and is used to control each first driving unit 2911 of the driving circuit layer 291. The anode layer 293 includes a plurality of transparent anodes 2931, which can be disposed corresponding to the first display area 210 of the display device 200, that is, the plurality of transparent anodes 2931 can be disposed corresponding to the first pixel definition area 2941. A transparent anode 2931 can be electrically connected to a sub-pixel 201 of the pixel definition layer 294.

[0057] A driving circuit layer 291 is disposed at intervals on the side of the anode layer 293 opposite to the pixel definition layer 294. The driving circuit layer 291 has multiple first driving units disposed in the area outside the first pixel definition region 2941. The area outside the first pixel definition region 2941 can refer to the area outside the first display area 210 or the area outside the second display area 220. Each first driving unit 2911 drives one sub-pixel 201. The first driving unit 2911 includes an opaque portion, such as a thin-film transistor (TFT).

[0058] A first transparent conductive layer 292 is disposed between the anode layer 293 and the driving circuit layer 291. The first transparent conductive layer 292 forms multiple curved transparent conductive lines 2921, which can be partially disposed corresponding to the first display area 210 and partially disposed corresponding to the second display area 220. Each transparent anode 2931 is electrically connected to a first driving unit 2911 through a transparent conductive line 2921.

[0059] A common electrode layer 295 is disposed on the pixel definition layer 294. The common electrode layer 295 can be disposed corresponding to the first display area 210 and the second display area 220. The anode layer 293 and the common electrode layer 295 are respectively disposed on both sides of the pixel definition layer 294, and together with the multiple first driving units 2911 of the driving circuit layer 291, they drive multiple sub-pixels 201.

[0060] In the display device 200 of this application embodiment, the driving circuit layer 291 can be electrically connected to the positive terminal of the power supply, and the common electrode layer 295 can be electrically connected to the negative terminal of the power supply. When the positive and negative terminals of the power supply are energized, the current flows in the driving circuit layer 291, the anode layer 293, the pixel definition layer 294 and the first transparent conductive layer 292, so that the sub-pixels 201 of the pixel definition layer 294 are driven and can emit light under the action of the current, so as to realize the display function of the display device 200.

[0061] In the electronic device 10 of this application embodiment, when the image sensor 700 is disposed inside the display device, when external light passes through the first display area 210 of the display device 200, a transparent anode 2931 is disposed in the anode layer 293 corresponding to the first display area 210. The transparent anode 2931 has less diffraction interference to external light. Furthermore, the opaque first driving unit 2911 is disposed in the area corresponding to the outside of the first display area 210. The opaque first driving unit 2911 does not affect the incident external light at all, resulting in a higher transmittance of external light in the first display area 210. At the same time, when external light passes through the circular or elliptical sub-pixels 201, the energy in the diffraction spectrum formed by the external light is more concentrated in the primary diffraction fringes, and the energy of each secondary diffraction fringes is lower, resulting in fewer secondary diffraction fringes, thereby reducing diffraction phenomena.

[0062] To further reduce diffraction interference, please refer to... Figure 5 , Figure 5 for Figure 4The diagram shows a first structural schematic of a sub-pixel. In the display device 200 of this application embodiment, each sub-pixel 201 may include a main body portion 2011 and an edge portion 2012 connected to each other. The cross-section of the main body portion 2011 can be circular or elliptical in a direction parallel to the pixel definition layer 294. The cross-section of the edge portion 2012 can be approximately annular, and this annular shape may include an outer contour and an inner contour. The inner contour surrounds and conforms to the outer periphery of the main body portion 2011, and the inner contour can be a closed circular or elliptical curve. The outer contour may include multiple curves with different curvatures, which, when connected end-to-end, can form a closed curve surrounding the main body portion 2011.

[0063] It is understandable that multiple curves with different curvatures can form an irregular closed curve surrounding the main body 2011. This irregular closed curve can refer to a curve that is not a regular polygon such as a regular triangle or quadrilateral; it is also not a common triangle, square, rectangle, or parallelogram; it is also not a regular circle or ellipse; and it is not a curve formed by connecting multiple identical arcs.

[0064] It is understandable that when the outer contour of the edge portion 2012 includes multiple curves, the curvature of any two adjacent curves can be different. Consequently, when light passes through any two adjacent curves, the diffraction phenomena formed are more likely to cancel each other out. Thus, when light passes through the entire edge portion 2012, the probability of diffraction is greatly reduced, and the diffraction phenomenon can be mitigated to the greatest extent.

[0065] In the display device 200 of this application embodiment, when the sub-pixel 201 includes an edge portion 2012 composed of curves with different curvatures, it is affected by the curves with different curvatures. When external light passes through the edge portion 2012 of the sub-pixel 201, the diffraction phenomena formed at different parts of the edge portion 2012 will cancel each other out, thereby reducing the formation of diffraction fringes and reducing diffraction interference.

[0066] Please refer to the following: Figure 6 , Figure 6 for Figure 4 The diagram shows a second structural representation of a subpixel. In the display device 200 of this application embodiment, each subpixel 201 may include a main body portion 2011 and a protrusion portion 2013 connected to each other. The protrusion portion 2013 may include a plurality of spaced protrusions that surround and protrude from the outer periphery of the main body portion 2011.

[0067] It is understandable that multiple protrusions can be composed of multiple curves with different curvatures, and each protrusion can extend from the outer edge of the main body 2011 in a direction away from the main body 2011. In this case, the outer periphery of the sub-pixel 201 can include multiple protrusions.

[0068] It is understandable that the number of protrusions can be around 20 to 30. In this case, the outer periphery of the edge 2012 can include 20 to 30 curves that are connected to each other, and the outer edge of the sub-pixel 201 can be an irregular curve.

[0069] In the display device 200 of this application embodiment, when the sub-pixel 201 includes an outer edge composed of multiple protrusions, since the protrusions have a greater bending curvature, when external light passes through the edge portion 2012 of the sub-pixel 201, the diffraction phenomena formed by different protrusions on the sub-pixel 201 will cancel each other out, thereby reducing the formation of diffraction fringes and reducing diffraction interference.

[0070] Please continue to refer to the following: Figure 5 and Figure 6 The diameter of the cross-section of sub-pixel 201 in the direction parallel to pixel definition layer 294 can be a non-integer multiple of half the target wavelength. It is understood that the target wavelength can be any wavelength within a certain band. For example, when the target wavelength is in the visible light band (380 nm to 750 nm band), the cross-sectional diameter of sub-pixel 201 can be a non-integer multiple of half the wavelength of any wavelength within the entire visible light band; that is, the cross-sectional diameter of sub-pixel 201 can avoid being an integer multiple of half the wavelength of any wavelength within the entire band.

[0071] It is understandable that a non-integer multiple of half the target wavelength means that the diameter of the cross-section of sub-pixel 201 is not an integer multiple of half the target wavelength, that is, diameter D ≠ n·1 / 2·λ (target wavelength), where n is a positive integer.

[0072] It is understandable that when the cross-section of sub-pixel 201 in the direction parallel to pixel definition layer 294 is circular, that is, when sub-pixel 201 is a cylindrical pixel, the diameter between any two points passing through the center on the cross-section of sub-pixel 201 in the direction parallel to pixel definition layer 294 can be a non-integer multiple of half the target wavelength. The center of sub-pixel 201 can be the center of the circular cross-section of sub-pixel 201 in the direction parallel to pixel definition layer 294.

[0073] It is understandable that when the cross-section of sub-pixel 201 in the direction parallel to pixel definition layer 294 is elliptical, that is, when sub-pixel 201 is an elliptical cylindrical pixel, the diameter between any two points passing through the center of the cross-section of sub-pixel 201 in the direction parallel to pixel definition layer 294 can also be a non-integer multiple of half the target wavelength. The center of sub-pixel 201 can be the intersection of the upper major axis and the semi-major axis of the elliptical cross-section of sub-pixel 201 in the direction parallel to pixel definition layer 294.

[0074] Based on optical principles, when light from outside the display device 200 passes through the sub-pixel 201, because the transmittance of the sub-pixel 201 differs from that of the air and the pixel gap area, the sub-pixel 201 acts as an obstacle relative to the air and the pixel gap area. As a result, the light deviates from its original straight-line propagation trajectory when passing through the sub-pixel 201, thus forming a diffraction phenomenon. In the display device 200 of this embodiment, the sub-pixel 201 has a circular or elliptical cross-section. When the sub-pixel 201 blocks light of the target wavelength, since the diameter of the sub-pixel 201's cross-section is a non-integer multiple of half the target wavelength, the energy can be more concentrated in the primary diffraction fringes. The energy of the secondary diffraction fringes is lower, resulting in fewer secondary diffraction fringes and thus mitigating the diffraction phenomenon.

[0075] Please refer to the following: Figure 7 , Figure 7 for Figure 4 The diagram shows a third structure of the sub-pixels. In the display device 200 of this application embodiment, the first pixel unit within the first pixel definition region 2941 may include a first sub-pixel 2014, a second sub-pixel 2015, and a third sub-pixel 2016 spaced apart. That is, sub-pixel 201 may include the first sub-pixel 2014, the second sub-pixel 2015, and the third sub-pixel 2016. In the direction parallel to the pixel definition layer 294, the cross-sectional area of ​​the first sub-pixel 2014 and the second sub-pixel 2015 may be larger than the cross-sectional area of ​​the third sub-pixel 2016.

[0076] Understandably, the first sub-pixel 2014, the second sub-pixel 2015, and the third sub-pixel 2016 can be made of organic light-emitting materials, which can emit light spontaneously under the influence of an electric current. For example, the first sub-pixel 2014 can emit light of a first color, the second sub-pixel 2015 can emit light of a second color, and the third sub-pixel 2016 can emit light of a third color. The first, second, and third colors can all be different.

[0077] Understandably, in the direction parallel to the pixel definition layer 294, the cross-section of the first sub-pixel 2014 and the second sub-pixel 2015 can be circular, and the cross-section of the third sub-pixel 2016 can be elliptical. The major axis of the ellipse can be equal to the diameter of the circle, and the minor axis of the ellipse can be smaller than the diameter of the circle, so that the cross-sectional area of ​​the third sub-pixel 2016 is smaller than the cross-sectional area of ​​the first sub-pixel 2014 and the second sub-pixel 2015.

[0078] It is understandable that the thickness of the first sub-pixel 2014, the second sub-pixel 2015, and the third sub-pixel 2016 can be the same. That is, within the first pixel definition area 2941, the upper surfaces of the first sub-pixel 2014, the second sub-pixel 2015, and the third sub-pixel 2016 can be on the same plane, and the lower surfaces of the first sub-pixel 2014, the second sub-pixel 2015, and the third sub-pixel 2016 can also be on the same plane.

[0079] In the display device 200 of this application embodiment, the cross-section of the third sub-pixel 2016 in the direction parallel to the pixel definition layer 294 is smaller than that of the first sub-pixel 2014 and the second sub-pixel 2015, so that the third sub-pixel 2016 occupies less space. Since light only diffracts when it passes through an obstacle, the probability of the third sub-pixel 2016, which occupies less space, producing diffraction is even lower, thereby reducing the probability of diffraction in the entire display device 200 and reducing diffraction interference.

[0080] Specifically, in the direction parallel to the pixel definition layer 294, when the cross-sectional area of ​​the first sub-pixel 2014 and the second sub-pixel 2015 is greater than the cross-sectional area of ​​the third sub-pixel 2016, the first sub-pixel 2014, the second sub-pixel 2015 and the third sub-pixel 2016 can be made of different light-emitting materials, so that the first sub-pixel 2014 can have a first light-emitting attenuation frequency, the second sub-pixel 2015 can have a second light-emitting attenuation frequency, and the third sub-pixel 2016 can have a third light-emitting attenuation frequency, and the first light-emitting attenuation frequency and the second light-emitting attenuation frequency can be greater than the third light-emitting attenuation frequency.

[0081] In the display device 200 of this application embodiment, when the light emission attenuation frequency of the first sub-pixel 2014 and the second sub-pixel 2015 is greater than the light emission attenuation frequency of the third sub-pixel 2016, after the same usage time, under the same current, the intensity of light emitted by the first sub-pixel 2014 and the second sub-pixel 2015 per unit area will decrease and will be less than the intensity of light emitted by the third sub-pixel 2016 per unit area. Since the cross-sectional area of ​​the first sub-pixel 2014 and the second sub-pixel 2015 is greater than the cross-sectional area of ​​the third sub-pixel 2016, the total intensity of light emitted by the first sub-pixel 2014 and the second sub-pixel 2015 can be the same as the total intensity of light emitted by the third sub-pixel 2016. Therefore, in the display device 200 of this application embodiment, the first sub-pixel 2014, the second sub-pixel 2015, and the third sub-pixel 2016 can emit light of the same brightness, which can compensate for pixel attenuation and improve the service life of the entire display device 200.

[0082] Please refer to the following: Figure 8 , Figure 8 for Figure 4 The diagram shows a fourth structure of the sub-pixels. In the display device 200 of this application embodiment, the first display area 210 may include a plurality of sub-pixels 201 spaced apart; that is, the plurality of sub-pixels 201 are spaced apart within the first pixel definition area 2941. Specifically, in the direction parallel to the pixel definition layer 294, the cross-sectional diameter d of the sub-pixel 201 may not be half the distance a between two adjacent sub-pixels 201; that is, the cross-sectional diameter of the sub-pixel 201 may be greater than or less than half the distance a between two adjacent sub-pixels 201.

[0083] It is understood that, in the direction parallel to the pixel definition layer 294, the cross-sectional diameter of the sub-pixel 201 can be referred to the aforementioned description, and will not be repeated here. It is understood that, as Figure 8 As shown, in the direction parallel to the pixel definition layer 294, the spacing 'a' between two adjacent sub-pixels 201 can be the distance between two points located on the edges of the two sub-pixels 201, wherein the line connecting the two points on the edges of the two sub-pixels 201 will pass through the center of the two sub-pixels 201 respectively.

[0084] It is understood that, in the direction parallel to the pixel definition layer 294, the cross-sections of the two sub-pixels 201 in this embodiment can both be elliptical, both can be circular, or one can be circular and the other elliptical. Of course, the two sub-pixels 201 in this embodiment can also be other shapes, and this embodiment does not limit their specific shapes.

[0085] Understandably, assuming the refractive index of the pixel spacing region of the first display area 210 is n1 and the thickness is d1, the refractive index of the sub-pixel 201 is n2 and the thickness is d2, the spacing between two adjacent sub-pixels 201 is a, the diameter of the sub-pixel 201 is d, and the distance of the light source from the first display area 210 is n0, then the transmittance function of light passing through the first display area 210 can be expressed as:

[0086]

[0087] Different diffraction patterns can be obtained by changing the values ​​of a and d respectively. For examples, please refer to [link / reference]. Figures 9 to 11 ,in, Figure 9 This is a first type of diffraction pattern for the first display area in an embodiment of this application. Figure 10 This is a second diffraction pattern for the first display area in an embodiment of this application. Figure 11 This is a third type of diffraction pattern for the first display area in an embodiment of this application. Furthermore, in Figures 9 to 11 In the image, the left side shows the diffraction intensity envelope of the first display area 210, and the right side shows the diffraction order distribution of the first display area 210.

[0088] exist Figure 9 In the image, the spacing 'a' between two adjacent sub-pixels 201 is 18 micrometers, and the diameter 'd' of sub-pixel 201 is 23 micrometers. Figure 10 In the image, the spacing 'a' between two adjacent sub-pixels 201 is 18 micrometers, and the diameter 'd' of sub-pixel 201 is 33 micrometers. Figure 11 In the image, the spacing a between two adjacent sub-pixels 201 is 18 micrometers, and the diameter d of sub-pixel 201 is 63 micrometers.

[0089] contrast Figures 9 to 11 It can be seen that the diffraction order spacing is inversely proportional to d. As d increases, the diffraction order spacing gradually decreases. When the ratio of a to d is close to a = 0.5d, the intensity of the ±1st order diffraction light is strongest. Based on this, in the display device 200 of this application embodiment, the diameter of the cross-section of the sub-pixel 201 can be less than half the spacing a between two adjacent sub-pixels 201. When light passes through the first display area 210, the intensity of the secondary diffraction light can be weaker, thereby reducing diffraction.

[0090] Please refer to the following: Figure 2 Please refer to Figure 12 , Figure 12 for Figure 2 The diagram shows a second cross-sectional view of the display device along the direction from P1 to P2.

[0091] The first display area 210 of the display device 200 includes a substrate 296, a driving circuit layer 291, a first planarization layer 298, a first transparent conductive layer 292, a second transparent conductive layer 297, an anode layer 293, a pixel definition layer 294, a common electrode layer 295, a second planarization layer 299, and a touch layer 290, which are stacked sequentially.

[0092] The substrate 296 can serve as a support platform for the display device 200. The substrate 296 can be made of glass, plastic, resin, or other materials. For example, the material of the substrate 296 can be polyimide (PI).

[0093] A driving circuit layer 291 is disposed on the substrate 296. The driving circuit layer 291 includes a first driving unit 2911 for driving the sub-pixels 201 of the first display area 210. Each first driving unit 2911 includes at least one thin-film transistor (TFT). The source and drain of the TFT are located in the same layer, and the gate is located between the source and the light-emitting layer.

[0094] An anode layer 293 is disposed on the driving circuit layer 291, electrically connected to the driving circuit layer 291, and used to control each first driving unit 2911 of the driving circuit layer 291. The anode layer 293 includes a plurality of transparent anodes 2931, which can be disposed corresponding to the first display area 210 of the display device 200, that is, the plurality of transparent anodes 2931 can be disposed corresponding to the first pixel definition area 2941. One transparent anode 2931 can be electrically connected to a sub-pixel 201 of the pixel definition layer 294.

[0095] The light-emitting layer 294 is disposed on the anode layer 293. The light-emitting layer 294 includes a first pixel definition region 2941. The first pixel definition region 2941 has a plurality of pixel holes. Each pixel hole is provided with a sub-pixel 201. The sub-pixel 201 includes an organic light-emitting material.

[0096] A first transparent conductive layer 292 is disposed between the anode layer 293 and the driving circuit layer 291. The first transparent conductive layer 292 forms multiple curved transparent conductive lines 2921, which can be partially disposed corresponding to the first display area 210 and partially disposed corresponding to the second display area 220. Each transparent anode 2931 is electrically connected to a first driving unit 2911 through a transparent conductive line 2921.

[0097] The second transparent conductive layer 297 is disposed between the anode layer 293 and the driving circuit layer 291. The second transparent conductive layer 297 can be stacked with the first transparent conductive layer 292; that is, the second transparent conductive layer 297 can be disposed between the driving circuit layer 291 and the first transparent conductive layer 292, or between the first transparent conductive layer 292 and the anode layer 293. The second transparent conductive layer 297 includes multiple transparent conductive sub-layers, each of which electrically connects a transparent anode 2931 to a first driving unit 2911. As the resolution of the first display area 210 increases, due to the size limitation of the electronic device 10, the first transparent conductive layer 292 cannot completely connect every sub-pixel 201. In this embodiment, the cooperation of the first transparent conductive layer 292 and the second transparent conductive layer 297 can connect to every sub-pixel 201 of the high-resolution first display area 210.

[0098] A first planarization layer 298 is disposed between the anode layer 293 and the drive circuit layer 291. The first planarization layer 298 has multiple vias 2981 extending through it in the thickness direction. These vias 2981 are used to pass through transparent conductive lines 2921 to electrically connect the first drive unit 2911 and the transparent anode 2931. The transparent conductive lines 2921 are routed through the vias 2981 on the first planarization layer 298, allowing for shorter traces to further reduce interference with light.

[0099] A common electrode layer 295 is disposed on the light-emitting layer 294, and the anode layer 293 and the common electrode layer 295 are disposed on both sides of the sub-pixel 201, and together drive the sub-pixel 201. The common electrode layer 295 can be made of ITO material with high light transmittance.

[0100] A second planarization layer 299 can also be provided on the common electrode layer 295. The sub-pixel 201 is placed after the pixel hole. The sub-pixel 201 does not fill the pixel hole. After the common electrode layer 295 is placed on the sub-pixel 201, a groove will appear. The second planarization layer 299 can fill the groove and cover the entire light-emitting layer 294 to protect the light-emitting layer 294, etc.

[0101] A touch layer 290 can also be disposed on the second planarization layer 299. The touch layer 290 can be used to detect user touch operations. A polarizer (not shown in the figure) can also be disposed on the touch layer 290. The polarizer can be used to prevent internal light from being transmitted out and to prevent the user from seeing internal components such as the driving unit. The touch layer 290 and the polarizer can be bonded together and then disposed on the planarization layer 296.

[0102] It should be noted that in some other embodiments, some structures may be added or removed as needed, and this application does not limit the scope of the embodiments. For example, at least one of the touch layer 290 and the polarizer may be removed. As another example, a protective layer may be added between the second planarization layer 299 and the touch layer 290, and the protective layer may be made of the same material as the substrate 296.

[0103] Except for the first driving unit 2911 in the driving circuit layer 291, all layers in the first display area 210 are made of light-transmitting materials to improve the light transmittance of the first display area 210. For example, the substrate 296, pixel definition layer 294, common electrode layer 295, first planarization layer 298, second planarization layer 299, and touch layer 290 of the first display area 210 can all be made of light-transmitting materials, and the signal lines in the anode layer 293 can be made of light-transmitting materials such as ITO or nano-silver. The TFT in the driving circuit layer 291 cannot be made of light-transmitting materials, but other parts of the driving circuit layer 291 besides the TFT can also be made of light-transmitting materials. It is understood that any scheme to improve the light transmittance of the first display area 210 by increasing the light transmittance of the materials and changing the wiring arrangement is within the scope of this application.

[0104] It should be noted that the second display area 220 can adopt a similar layered structure to the first display area 210, as detailed in the above embodiments, which will not be repeated here. At least one of the substrate, pixel definition layer, common electrode layer, planarization layer, and touch layer of the second display area 220 can use the same light-transmitting material as the first display area 210. For example, the substrate can be a light-transmitting material such as glass or resin. At least one of the substrate, pixel definition layer, common electrode layer, planarization layer, and touch layer of the second display area 220 can use different materials than the first display area 210. For example, the signal lines in the anode layer 293 of the second display area 220 can be made of metals or alloys such as molybdenum, aluminum molybdenum, or Ag. Since the second display area 220 does not have a light-shielding block, the metal anode of the second display area 220 can be made of metal materials such as Mg, Ag, or Al. The common electrode layer of the second display area 220 can be made of materials such as Mg or Ag. The common electrode layer of the second display area 220 and the common electrode layer of the first display area 210 are connected at their edges, forming a complete common electrode layer 295. The light-emitting layer of the second display area 220 includes multiple sub-pixels. The material of the sub-pixels of the second display area 220 can be the same as the material of the sub-pixels 201 of the first display area 210, and they can also have the same light transmittance. Alternatively, the sub-pixels of the second display area 220 can be different from the sub-pixels 201 of the first display area 210, so that the light transmittance of the first display area 210 is greater than that of the second display area 220.

[0105] Please refer to this again. Figure 4In the display device 200 of this application embodiment, the pixel definition layer 294 may further include a second pixel definition region 2942, which may correspond to the driving circuit layer 291 and be located in the area outside the first pixel definition region 2941. That is, the orthographic projection of the first driving unit 2911 on the pixel definition layer 294 is located in the second pixel definition region 2942.

[0106] It is understood that the second pixel definition region 2942 can form at least one second pixel unit, and when multiple second pixel units are included, the multiple second pixel units can be arranged at intervals. The second pixel unit can include multiple fourth sub-pixels 202, for example, the second pixel unit can include red light sub-pixels, green light sub-pixels, and blue light sub-pixels. In the direction parallel to the pixel definition layer 294, the cross-sectional area of ​​the fourth sub-pixel 202 can be larger than the cross-sectional area of ​​the sub-pixel 201.

[0107] It is understood that the second pixel definition area 2942 can be disposed in the second display area 220, and the second pixel definition area 2942 can be disposed adjacent to and connected to the first pixel definition area 2941. The first pixel definition area 2941 and the second pixel definition area 2942 can be located inside the cover plate 100 so that the cover plate 100 can protect the first pixel definition area 2941 and the second pixel definition area 2942.

[0108] It is understandable that the first pixel definition area 2941 and the second pixel definition area 2942 can be set on the same layer. Setting on the same layer means that the outer surface of the first pixel definition area 2941 can be on the same plane as the outer surface of the second pixel definition area 2942, and the inner surface of the first pixel definition area 2941 can be on the same plane as the inner surface of the second pixel definition area 2942.

[0109] Understandably, in the direction parallel to the pixel definition layer 294, the cross-section of the fourth sub-pixel 202 of the second pixel unit can be circular or elliptical, just like the sub-pixel 201 of the first pixel unit, in order to reduce diffraction interference.

[0110] It is understood that the driving circuit layer 291 is provided with a plurality of second driving units (not shown in the figure) in the area corresponding to the second pixel definition area 2942, and each second driving unit is electrically connected to a fourth sub-pixel 202 of the second pixel unit to drive a fourth sub-pixel 202.

[0111] It is understood that the anode layer 293 may be provided with multiple metal anodes (not shown), and the metal anodes may be disposed in the second display area 220. Each metal anode may be electrically connected to a fourth sub-pixel 202 of the second pixel unit. The display device 200 may also include a conductive layer (not shown), which is disposed in the second display area 220 and forms multiple curved conductive lines. Each metal anode is electrically connected to a fourth sub-pixel 202 through a conductive line.

[0112] In the display device 200 of this application embodiment, the opaque first driving unit 2911 is orthogonally projected onto the second pixel definition region 2942. The opaque first driving unit 2911 does not affect the external light incident on the first pixel definition region 2941, resulting in higher transmittance of external light in the region corresponding to the first pixel definition region 2941. Furthermore, the cross-sectional area of ​​the second pixel unit 202 is larger than the cross-sectional area of ​​the sub-pixel 201, and the size of the sub-pixel 201 is smaller than the size of the second pixel unit 202. Consequently, the sub-pixel 201 occupies a smaller area, the pixel spacing within the first display area 210 is larger, the transmittance of the first display area 210 is higher, and the probability of diffraction is lower.

[0113] It is understandable that, in the direction parallel to the pixel definition layer 294, when the cross-sectional area of ​​the fourth sub-pixel 202 can be larger than the cross-sectional area of ​​the sub-pixel 201, a light-emitting material with a specific decay frequency can be selected, so that the decay frequency of the fourth sub-pixel 202 is greater than the decay frequency of the sub-pixel 201, thereby ensuring the consistency of the display of the first display area 210 and the second display area 220, and the first display area 210 and the second display area 220 will not have obvious boundary when displaying information.

[0114] The transmittance of the first display area 210 can be greater than that of the second display area 220. It is understandable that there are multiple ways to achieve a higher transmittance for the first display area 210 than for the second display area 220.

[0115] For example, the first display area 210 may include a plurality of sub-pixels 201, and the second display area 220 may include a plurality of fourth sub-pixels 202. The pixel density of the plurality of sub-pixels 201 may be less than the pixel density of the plurality of fourth sub-pixels 202, so that the spacing between the plurality of sub-pixels 201 in the first display area 210 is larger, thereby increasing the area that can transmit light, so that the light transmittance of the first display area 210 is greater than that of the second display area 220.

[0116] Understandably, in order to further improve the light transmittance of the first display area 210, the sub-pixels 201 of the first display area 210 are made of a light-transmitting material, such as indium tin oxide.

[0117] It is understandable that multiple fourth sub-pixels 202 and multiple sub-pixels 201 can be arranged in an array. The arrangement of sub-pixels 201 in the first display area 210 can be one of a standard RGB arrangement, a Pentile arrangement, or a Delta arrangement, and the arrangement of fourth sub-pixels 202 in the second display area 220 can be one of a standard RGB arrangement, a Pentile arrangement, or a Delta arrangement. It should be noted that sub-pixels 201 in the first display area 210 can also be arranged in other ways, and fourth sub-pixels 202 in the second display area 220 can also be arranged in other ways.

[0118] For example, a plurality of driving circuit layers 291 are provided in the display device 200. The first driving layer (not shown) is connected to and drives the sub-pixel 201, and the second driving layer (not shown) is connected to and drives the fourth sub-pixel 202. The first driving layer is disposed inside the second driving layer. The second driving layer is provided with a via 2981 that penetrates its thickness direction. The driving trace passes through the via 2981 to electrically connect the first driving unit 2911 in the first driving layer to the sub-pixel 201.

[0119] It is understandable that the driving unit can employ one of the following driving circuits: 2T1C, 5T1C, or 7T1C. For example, the first driving unit 2911 can employ one of 2T1C, 5T1C, or 7T1C, and the second driving unit can employ one of 2T1C, 5T1C, or 7T1C. Here, T represents a thin-film transistor, and C represents a capacitor. To improve the light transmittance of the first display area 210, the first driving unit 2911 in the first display area 210 can be a simpler driving circuit than the main driving unit of the second display area 220. For example, the first driving unit 2911 includes fewer thin-film transistors than the second driving unit. For example, the first driving unit 2911 can employ one of 2T1C or 5T1C, and the second driving unit can employ 7T1C. The first driving unit 2911 has fewer opaque thin-film transistors, resulting in less opaque portion in the first display area 210, thus improving the light transmittance of the first display area 210.

[0120] For example, the first display area 210 and the second display area 220 may have the same pixel physical structure. However, multiple sub-pixels 201 in the first display area 210 may be connected in parallel to a signal line to form a pixel set. This can reduce the number of signal lines connecting the sub-pixels 201 to the signal line, thereby improving the light transmittance of the first display area 210.

[0121] It is understood that the above are merely examples of solutions to achieve a higher light transmittance of the first display area 210 than that of the second display area 220. The solutions of this application are not limited to these, and other solutions that can achieve a higher light transmittance of the first display area 210 than that of the second display area 220 are all within the protection scope of this application.

[0122] Please refer to the following: Figure 13 , Figure 13 for Figure 1 The diagram shows a second possible structure of the display device. The display device 200 may further include a non-display area 230. The non-display area 230 may be located at the periphery of the second display area 220, and the non-display area 230 may be interconnected with the second display area 220.

[0123] It is understood that the first driving unit 2911 is located within the non-display area 230, and the transparent conductive line 2921 is connected to the sub-pixel 201 and the first driving unit 2911 respectively, so that the first driving unit 2911 can drive the sub-pixel 201 to emit light.

[0124] It is understandable that the non-display area 230 may not have a display function and may not be able to display an image. It is understandable that the non-display area 230 may be located in the top area of ​​the electronic device 10, or in the bottom area of ​​the electronic device 10, or simultaneously in the top and bottom areas of the electronic device 10, or in the top, bottom, and two oppositely positioned sides of the electronic device 10.

[0125] Understandably, the transparent conductive line 2921 can be a curved trace. The transparent conductive line 2921 can be made of a transparent material, such as tin oxide.

[0126] In the display device 200 of this application embodiment, the first driving unit 2911 is disposed in the non-display area 230. The first driving unit 2911 does not occupy the space of the first display area 210, allowing for higher transmittance in the first display area 210. External light will not encounter the first driving unit 2911 within the first display area 210 and thus avoid diffraction, thereby reducing diffraction interference to the first display area 210. Simultaneously, the transparent conductive line 2921 uses an arc-shaped trace. When external light encounters the arc-shaped trace, the diffraction phenomena formed at different locations on the arc-shaped trace will cancel each other out, further reducing the formation of diffraction fringes and minimizing diffraction interference.

[0127] The first pixel definition area 2941 and the second pixel definition area 2942 of the first display area 210 and the second display area 220 can be OLED display layers. The OLED display layer can include layered structures such as hole transport layer, organic light-emitting layer, and electron transport layer. When current passes between the anode layer 293 and the common electrode layer 295, electrons and holes injected by the electrode recombine in the light-emitting layer to form excitons. The excitons radiate de-excitation to emit photons and generate visible light.

[0128] Because OLED pixels are self-emissive, the emitted light can be transmitted to the outside of the display device 200 and absorbed by the human eye. The emitted light can also be transmitted into the display device 200; this light transmitted into the display device 200 is generally referred to as screen leakage. This portion of light is not received by the human eye, affecting the brightness of the display device 200 and also reducing the pixel transmittance, resulting in diffraction. To improve the brightness of the display device 200, related technologies often add reflective materials, such as silver, to the anode layer 293. When light passes through the OLED pixels, the reflection from the silver material can reflect the screen leakage from the first pixel definition area 2941 and the second pixel definition area 2942 to the outside of the display device 200.

[0129] Adding reflective material to the anode layer 293 can improve the brightness of the display device 200, but it will reduce the light transmittance of the pixels in the display layer. When light passes through the display device 200, diffraction will occur, which will seriously affect the light collection and shooting effect of the image sensor 700.

[0130] Therefore, please refer to Figure 14 , Figure 14 for Figure 2 The diagram shows a third cross-sectional view of the display device along the direction from P1 to P2. In the display device 200 of this application embodiment, the second display area 220 can be provided with reflective material in the anode layer 293 of the second pixel definition area 2942 to form a reflective layer 270 in the second pixel definition area 2942, so as to ensure the display brightness of the display device 200.

[0131] It is understandable that the reflective layer 270 can also be set on one side of the second pixel definition area 2942, such as the inner side, to ensure the display brightness of the display device 200.

[0132] It is understandable that the first pixel definition area 2941 may not contain reflective material within the anode layer 293, thus preventing the formation of the reflective layer 270.

[0133] To simultaneously balance display brightness and image sensor 700 capture performance, the display device 200 of this embodiment may further include a blocking member, which may be disposed between the first pixel definition area 2941 and the image sensor 700. The blocking member can switch between a first state and a second state. In the first state, the blocking member can reflect or absorb light emitted from the first pixel definition area 2941 and the second pixel definition area 2942 outside the display device 200. In the second state, the blocking member allows at least a portion of ambient light to pass through the display device 200 and enter the image sensor 700.

[0134] Please refer to the following: Figure 15 and Figure 16 , Figure 15 for Figure 1 The diagram shows a first cross-sectional view of the electronic device along M1 to M2. Figure 16 for Figure 1 The diagram shows a second cross-sectional view of the electronic device along M1 to M2. The blocking element can be an electroreflective layer 240, which can be disposed between the display device 200, for example, the first pixel definition area 2941, and the image sensor 700. The electroreflective layer 240 can be positioned directly opposite the first pixel definition area 2941 and the first display area 210. Furthermore, under the influence of current, the electroreflective layer 240 can achieve a reversible change from a low-transmittance colored state to a high-transmittance achromatic state.

[0135] For example, such as Figure 15 As shown, in the unpowered state, the electroreflective layer 240 of this embodiment can present a colored first state. In the first state, the electroreflective layer 240 has a low light transmittance, and the light emitted from the first pixel definition area 2941 and the second pixel definition area 2942 cannot pass through the electroreflective layer 240. Furthermore, the electroreflective layer 240 can preferably be made of a material with reflective function, so that in the first state, the electroreflective layer 240 can also reflect the light emitted from the organic light-emitting layer to the outside of the display device 200.

[0136] like Figure 16 As shown, when powered on, the electroreflective layer 240 of this embodiment can exhibit a transparent second state. In the second state, the electroreflective layer 240 has a high light transmittance, and ambient light can pass through the electroreflective layer 240 and enter the image sensor 700. Furthermore, in the second state, the electroreflective layer 240 can allow at least a portion of the ambient light to pass through the display device 200 and enter the image sensor 700.

[0137] The blocking element can also be an electro-absorbing layer, which can be disposed between the display device 200, for example, the first pixel definition area 2941 and the image sensor 700. The electro-absorbing layer can be disposed directly opposite the first pixel definition area 2941 and the first display area 210. Furthermore, under the action of current, the electro-absorbing layer can also achieve a reversible change from a colored state with low light transmittance to a colorless state with high light transmittance.

[0138] For example, in the unpowered state, the electro-absorbing layer of this embodiment can exhibit a colored first state. In the first state, the electro-absorbing layer has low light transmittance, and light emitted from the first pixel definition area 2941 and the second pixel definition area 2942 cannot pass through the electro-absorbing layer and can be absorbed by the electro-absorbing layer. In the powered state, the electro-absorbing layer of this embodiment can exhibit a transparent second state. In the second state, the electro-absorbing layer has high light transmittance, and ambient light can pass through the electro-absorbing layer and enter the image sensor 700. Furthermore, in the second state, the electro-absorbing layer allows at least a portion of the ambient light to pass through the display device 200 and enter the image sensor 700.

[0139] Please refer to the following: Figure 17 and Figure 18 , Figure 17 for Figure 1 The diagram shows a third cross-section of the electronic device along M1 to M2. Figure 18 for Figure 1 The diagram shows a fourth cross-sectional view of the electronic device along M1 to M2. The blocking element can also be a reflective element 250. The electronic device 10 may also include a driving mechanism 260, which can be electrically connected to the reflective element 250. Under the action of the driving mechanism 260, the reflective element 250 can switch between a first state and a second state. In the first state, the reflective element 250 is positioned directly opposite the first pixel definition area 2941. In the second state, the reflective element 250 is positioned at least partially offset from the first pixel definition area 2941.

[0140] like Figure 17 As shown, when the reflective element 250 is in the first state, the reflective surface of the reflective element 250 can be positioned directly opposite the light-emitting surface of the first pixel definition area 2941. The projection of the reflective surface of the reflective element 250 onto the first pixel definition area 2941 can cover the first pixel definition area 2941 and the light-emitting surface, so that the reflective element 250 can reflect all the light emitted from the first pixel definition area 2941 to the outside of the display device 200.

[0141] like Figure 18As shown, when the reflective element 250 is in the second state, the reflective surface of the reflective element 250 can be completely or partially offset from the emitting surface of the first pixel definition area 2941. This offset arrangement can mean that the projection of the reflective element 250 onto the first pixel definition area 2941 does not intersect with the first pixel definition area 2941 at all, and the projection of the reflective surface onto the first pixel definition area 2941 does not intersect with the projection of the emitting surface onto the first pixel definition area 2941 at all. At this time, the reflective element 250 does not completely block the first pixel definition area 2941, and the light emitted from the first pixel definition area 2941 can directly enter the interior of the display device 200 without reflection and be received and detected by the image sensor 700.

[0142] It is understandable that this staggered arrangement can also mean that the projection of the reflective element 250 onto the first pixel definition area 2941 does not intersect with a portion of the first pixel definition area 2941, and the projection of the reflective surface onto the first pixel definition area 2941 does not intersect with the projection of the emitting surface onto the first pixel definition area 2941. In this case, the reflective element 250 does not completely block the first pixel definition area 2941, and a portion of the light emitted from the first pixel definition area 2941 can directly enter the interior of the display device 200 without reflection and be received and detected by the sensor.

[0143] Of course, the offset setting can also refer to the fact that the reflective surface of the reflective element 250 and the light-emitting surface are at a preset angle. The preset angle can be greater than zero degrees and less than 360 degrees, so that the reflective surface is not completely facing the light-emitting surface. At this time, some of the light emitted from the first pixel definition area 2941 can pass through the reflective element 250 without being reflected, so that it can enter the interior of the display device 200 and be received and detected by the image sensor 700.

[0144] It is understood that the driving mechanism 260 can be a motor driving mechanism. For example, the driving mechanism 260 can include a motor and a slide rail. The slide rail can be set on one side, such as the inner side, of the first pixel definition area 2941. The motor shaft can be connected to the reflective element 250. The motor drives the reflective element 250 to slide on the slide rail so that the reflective element 250 can be set directly opposite to the first pixel definition area 2941 and cover the first display area 210, or the reflective element 250 can be set away from the first pixel definition area 2941 and away from the first display area 210.

[0145] For example, the driving mechanism 260 can also be an electromagnetic driving mechanism. For instance, the driving mechanism 260 may include two magnets, a spring, and an electromagnetic circuit. The two magnets are respectively disposed on the reflective element 250 and the first pixel definition area 2941. One end of the spring is connected to the reflective element 250, and the other end of the spring can be fixed to the structure of the second display area 220. When the electromagnetic circuit is on, under the action of magnetic attraction, the reflective element 250 is positioned directly opposite the first pixel definition area 2941 and covers the first display area 210, at which time the spring is stretched. When the electromagnetic circuit is off, the magnetic attraction between the reflective element 250 and the first pixel definition area 2941 disappears, and the reflective element 250 is pulled back to its initial position by the spring. That is, the reflective element 250 is offset from the first pixel definition area 2941 and moved away from the first display area 210.

[0146] Of course, the driving mechanism 260 in this application embodiment is not limited to the examples above. The driving mechanism 260 can also be other driving mechanisms, such as a cylinder driving mechanism, a motor gear driving mechanism, a motor belt driving mechanism, etc. Any driving mechanism 260 that can switch the reflective element 250 between the first state and the second state is within the protection scope of this application.

[0147] In the display device 200 and electronic device 10 of this application embodiment, the blocking member can switch between a first state and a second state. When the blocking member is in the first state, it can completely block the first pixel definition area 2941, and can completely reflect or absorb the light emitted from the first pixel definition area 2941 outside the display device 200, thereby ensuring the brightness of the display device 200 and reducing reflection. When the blocking member is in the second state, it cannot completely block the first pixel definition area 2941, and light can directly enter the display device 200 without passing through the blocking member and be received by the image sensor 700. Thus, on the one hand, the light transmittance of the display device 200 can be improved, and on the other hand, the multiple sub-pixels 201 of the first pixel definition area 2941 will not form a diffraction grating, and will not affect the shooting effect of the image sensor 700.

Furthermore, those skilled in the art will recognize that, based on the ideas of this application, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this application.
