[0026] Please refer to Figures 1 and 2. Figure 1 is a schematic diagram of the structure of the electronic device 10 in some embodiments, and Figure 2 is a schematic diagram of the structure of the display panel 20 in some embodiments. The display panel 20 provided in this application includes but is not limited to any applicable display device or touch display device such as an OLED display screen. The display panel 20 can be used in the electronic device 10 to enable the electronic device 10 to realize the display function or the touch display function. The electronic device 10 includes but is not limited to a smartphone, a tablet computer, an e-reader, etc. The electronic device 10 may include a housing 11 or a middle frame, and the display panel 20 may be provided on the housing 11 or the middle frame, and the light-emitting surface of the display panel 20 is exposed on the housing 11 or the middle frame. In this application, a smartphone is used as an example of the electronic device 10.

[0027] In some embodiments, the display panel 20 is a self-luminous display device. The display panel 20 includes a pixel definition layer 21 and a color filter film 22. The pixel definition layer 21 is provided with a plurality of light-emitting units 211 arranged in an array. The light-emitting units 211 may include red light-emitting devices, blue light-emitting devices, and green light-emitting devices. The three light-emitting units 211 together form a light-emitting array to achieve a color display function. The pixel definition layer 21 may also include a black color resist 212. The black color resist 212 defines a plurality of pixel opening areas arranged in an array. The light-emitting units 211 are arranged one-to-one in the pixel opening areas defined by the black color resist 212. The area where the black color resist 212 is located is considered a non-opening area. Each light-emitting unit 211 can be regarded as a sub-pixel unit of the display panel 20. An adjacent red light-emitting device, a blue light-emitting device, and a green light-emitting device together constitute a pixel unit of the display panel 20.

[0028] In some embodiments, a color filter film 22 is disposed on the light-emitting side of the pixel definition layer 21. The color filter film 22 includes a black matrix 221 and a color filter matrix 222 disposed in the same layer. The black matrix 221 corresponds to the non-opening area, that is, it is disposed opposite the black color resist 212 of the pixel definition layer 21. The color filter matrix 222 is disposed opposite the light-emitting unit 211. Light emitted by the light-emitting unit 211 is modulated by the color filter matrix 222 before being emitted. In FIG2 , the black matrix 221 is hatched to facilitate distinction between the black matrix 221 and the color filter matrix 222. The color filter matrix 222 may include a plurality of filter portions 2221 arranged in an array. The black matrix 221 is disposed around the filter portions 2221. The filter portions 2221 may be divided into red, blue, and green color resists. The red color resists are disposed opposite the red light-emitting device in the light-emitting unit 211, the blue color resists are disposed opposite the blue light-emitting device, and the green color resists are disposed opposite the green light-emitting device. Using the color filter film 22 in the display panel 20 instead of the traditional polarizer is beneficial to improving the light extraction efficiency of the display panel 20 , thereby helping to reduce the power consumption of the display panel 20 and improve the display brightness.

[0029] In some embodiments, the display panel 20 further includes a microlens array layer 23, which is disposed between the pixel definition layer 21 and the color filter film 22 and includes a refractive layer 231 and a plurality of microlens portions 232 arranged in an array. The plurality of microlens portions 232 are aligned one-to-one with the plurality of light-emitting units 211, and the refractive layer 231 covers the microlens portions 232 on the side of the microlens portions 232 facing away from the pixel definition layer 21. For example, the display panel 20 further includes an encapsulation layer 24 for encapsulating the pixel definition layer 21. The encapsulation layer 24 is disposed on the side of the pixel definition layer 21 facing the color filter film 22 and covers the pixel definition layer 21. The microlens portions 232 are disposed on the surface of the encapsulation layer 24 facing away from the pixel definition layer 21, and the refractive layer 231 is laid flat on the encapsulation layer 24, covering the microlens portions 232 and filling the gaps between adjacent microlens portions 232. It is understood that at least a portion of the light emitted by the light-emitting unit 211 is sequentially regulated by the microlens portion 232, the refractive layer 231, and the color filter matrix 222 before being emitted. In some embodiments, the refractive index of the material of the refractive layer 231 is less than the refractive index of the material of the microlens portion 232. It should be noted that the embodiment shown in FIG2 only illustrates two of the light-emitting units 211 of the display panel 20, as well as the two microlens portions 232 corresponding to the two light-emitting units 211 and the two filter portions 2221 in the color filter matrix 222. In practice, the number of light-emitting units 211, the number of light-emitting devices, and the arrangement rules need to be set according to display requirements and are not limited in this application. The filter portions 2221, the microlens portions 232, and the light-emitting units 211 are arranged one-to-one. The number and arrangement rules of the microlens portions 232 and the filter portions 2221 in the color filter matrix 222 can be adapted to the light-emitting units 211.

[0030] The display panel 20 described above has a microlens array layer 23 disposed between the pixel definition layer 21 and the color filter film 22. The refractive index of the material of the refractive layer 231 is designed to be lower than the refractive index of the material of the microlens portion 232. When light passes from the microlens portion 232 to the refractive layer 231, that is, from an optically dense medium to an optically rarefying medium, the light's exit angle is reduced, for example, by reducing the angle between the light and the axis of the microlens portion 232. Firstly, the matching refractive indices of the microlens portion 232 and the refractive layer 231 can focus the light emitted by the light-emitting unit 211, thereby reducing the light's exit angle and increasing the brightness attenuation at wide viewing angles, thereby facilitating the implementation of an anti-peep screen function. For example, at a 30° viewing angle, the brightness attenuation of the display panel 20 can reach over 40%, achieving an effective anti-peep screen design. Secondly, the focusing effect of the microlens array layer 23 reduces the area of ​​light coverage on the color filter 22, thereby reducing the amount of light that strikes the black matrix 221 of the color filter 22. This reduces the probability of light being absorbed by the black matrix 221, allowing more light to be emitted from the color filter matrix 222. This improves the light extraction efficiency of the display panel 20 and reduces the power consumption of the display panel 20. For example, the combination of the microlens array layer 23 and the color filter 22 can increase the light extraction efficiency of the display panel 20 from the traditional 20% to 40% or above, thereby reducing the power consumption of the display panel 20 by approximately 40%. Third, the reflectivity of the microlens array layer 23 to ambient light is generally higher than that of the color filter film 22. Positioning the microlens array layer 23 on the back side of the color filter film 22 keeps it away from the light-emitting surface of the display panel 20, thus preventing the display panel 20 from excessively increasing its reflectivity to ambient light. This helps reduce reflections from the display panel 20, preventing them from affecting display quality. This allows the display panel 20 to achieve better display quality at lower brightness, and also helps reduce power consumption. Fourth, the refractive index coordination between the microlens portion 232 and the refractive layer 231 achieves light focusing. Compared to traditional methods of refraction achieved through microlens reflection, this method maintains good light uniformity while focusing the light, improving color uniformity. This improves color shift at wide viewing angles, such as those between 45° and 80°, and balances color at both narrow and wide viewing angles, thus improving the display quality of the display panel 20.

[0031] In some embodiments, the refractive index of the microlens portion 232 is greater than or equal to 1.6 and less than or equal to 1.8, for example, 1.6, 1.7, or 1.8. The refractive index of the refractive layer 231 is greater than or equal to 1.4 and less than or equal to 1.53, for example, 1.4, 1.5, or 1.53. The material of the microlens portion 232 and the refractive layer 231 can both be organic glass, such as OC glass, which helps to improve the drop resistance and chemical stability of the display panel 20. Of course, the material of the microlens portion 232 and the refractive layer 231 can also be any other suitable material, as long as it can meet the corresponding refractive index requirements and light transmittance requirements.

[0032] In some embodiments, the dimension of the microlens portion 232 in the direction from the pixel definition layer 21 to the color filter 22 is greater than or equal to 3 μm and less than or equal to 10 μm, for example, 3 μm, 5 μm, 8 μm, or 10 μm. This configuration allows the microlens portion 232 to effectively deflect light while also minimizing the thickness of the microlens array layer 23, thereby reducing the thickness of the display panel 20. In some embodiments, the microlens portion 232 can be fabricated by first applying a coating process to the encapsulation layer 24, followed by etching to form a plurality of microlens portions 232 arranged in an array. The coating process allows for better control of the thickness of the microlens portion 232, thereby reducing the thickness of the microlens array layer 23. After the microlens portion 232 is fabricated, the refractive layer 231 can be fabricated on the side of the microlens portion 232 and the encapsulation layer 24 facing away from the pixel definition layer 21 using any suitable process, such as coating or inkjet printing.

[0033] In conjunction with Figures 2 and 3 , Figure 3 can be viewed as a schematic diagram of the projections of the light-emitting unit 211, the microlens portion 232, and the color filter matrix 222 onto the light-emitting surface of the display panel 20, wherein R represents a red light-emitting device, B represents a blue light-emitting device, and G represents a green light-emitting device. The radial dimension of the light-emitting unit 211 of the present application can be between 4 μm and 15 μm, and can be specifically set according to display requirements. In the embodiment shown in Figure 3 , the opening shape of the pixel definition layer 21 is circular. In other embodiments, the opening shape of the pixel definition layer 21 can also be any suitable shape, such as an ellipse, square, rectangle, or diamond. The shapes of the microlens portion 232 and the filter portion 2221 can also be adjusted to adapt to the opening shape of the pixel definition layer 21. In some embodiments, the projection of the microlens portion 232 on the pixel definition layer 21 covers the light-emitting surface of the light-emitting unit 211, allowing the microlens portion 232 to focus more light emitted by the light-emitting unit 211, effectively improving light extraction efficiency and reducing power consumption. It can also effectively improve brightness attenuation at wide viewing angles, thereby better implementing an anti-peep screen design. In some embodiments, the projection of the color filter matrix 222 on the microlens array layer 23 covers the microlens portion 232, allowing more light passing through the microlens array layer 23 to be emitted through the color filter matrix 222 without being easily blocked by the black matrix 221. This also helps to improve the light extraction efficiency of the display panel 20 and reduce the power consumption of the display panel 20.

[0034] For example, in some embodiments, the radial dimension of the projection of the filter portion 2221 on the light-emitting surface of the display panel 20 is larger than the radial dimension of the microlens portion 232 opposite the filter portion 2221, and the radial dimension of the projection of the microlens portion 232 on the light-emitting surface is larger than the radial dimension of the light-emitting surface of the light-emitting unit 211 opposite the microlens portion 232. This allows the microlens array layer 23 and the color filter film 22 to fully regulate light, improve light extraction efficiency, reduce power consumption, and enhance display quality.

[0035] It should be noted that, in the embodiment illustrated in the present application, each light-emitting unit 211 is matched with a microlens portion 232, and the projection of one microlens portion 232 on the pixel definition layer 21 covers one light-emitting unit 211. In other embodiments, each light-emitting unit 211 may also be matched with multiple microlens portions 232, and the projection of each multiple microlens portion 232 on the pixel definition layer 21 covers one light-emitting unit 211.

[0036] In some embodiments, the side of the microlens portion 232 facing away from the pixel definition layer 21 is configured as a convex surface. In other words, when the surface of the encapsulation layer 24 facing away from the pixel definition layer 21 and used to support the microlens portion 232 is a flat surface, the thickness of the middle portion of the microlens portion 232 is greater than the thickness of the edge portion. As a result, the microlens portion 232 is generally convex in shape, which better matches the refractive index of the microlens portion 232 and the refractive layer 231 to achieve stronger light focusing ability, thereby further reducing the probability of light hitting the black matrix 221 and improving brightness attenuation at wide viewing angles, thereby reducing the power consumption of the display panel 20 and achieving a better anti-peep screen design.

[0037] The specific configuration of the convex surface of the microlens portion 232 is not limited, as long as it can further enhance the light-gathering capability of the microlens portion 232. In some embodiments, the convex surface of the microlens portion 232 is defined as a first surface 2321. The first surface 2321 includes a middle portion and a peripheral portion, with the peripheral portion being disposed around the periphery of the middle portion. The middle portion is generally planar, for example, generally parallel to the light-emitting surface of the light-emitting unit 211, and the peripheral portion is curved. Thus, while enhancing the light-gathering capability of the microlens portion 232, it can effectively balance the incident and exit angles of high-angle and low-angle light, improving the uniformity of light color, thereby improving the display quality of the display panel 20 and alleviating color shift at wide viewing angles. When the peripheral portion is curved, a grayscale mask can be used for exposure processing during etching to prepare the microlens portion 232. The grayscale mask can be used to control different exposure levels for different portions, for example, with higher or lower exposure levels for locations closer to the edge, thereby forming a curved peripheral portion.

[0038] Of course, the shape of the microlens portion 232 can also have any other applicable design as long as it can effectively deflect light. For example, in the direction perpendicular to the plane where the pixel definition layer 21 is located, the cross-sectional shape of the microlens portion 232 includes but is not limited to an arc shape, a triangle or a trapezoid, etc.

[0039] In some embodiments, in the direction from the pixel definition layer 21 to the microlens array layer 23, the encapsulation layer 24 includes a first inorganic layer 241, an organic layer 242, and a second inorganic layer 243, which are stacked in sequence. The materials of the first inorganic layer 241 and the second inorganic layer 243 can be the same or different inorganic materials. The materials of the first inorganic layer 241 and the second inorganic layer 243 include, but are not limited to, one or more of silicon oxide (SiOx), silicon nitride (SiNx), silicon oxynitride (SiOxNy), ZnSe, ZnO, Sb2O3, Al2O3, In2O3, or SnO2. The material of the organic layer 242 includes, but is not limited to, acrylic polymers. The organic layer 242 can block the penetration of external moisture or oxygen, thereby providing encapsulation and protection for the pixel definition layer 21. The organic layer 242 can also planarize the inorganic layer by blocking defects in the inorganic layer, thereby improving the light extraction efficiency of the display panel 20.

[0040] Furthermore, in some embodiments, the thickness of the organic layer 242 is greater than or equal to 12um, for example, it can be 12um, 14um or 18um. It is understandable that the thickness of the encapsulation layer 24 affects the angle of light exiting the encapsulation layer 24. The thicker the encapsulation layer 24, the more high-angle light exits from the encapsulation layer 24. Therefore, setting the thickness of the organic layer 242 to 12um or above can increase the probability that the high-angle exiting light is blocked by the black matrix 221, and increase the brightness attenuation at a large angle viewing angle, thereby effectively realizing the anti-peep screen design. At the same time, it is also beneficial to avoid the inorganic layer being too thick and affecting the flatness of the encapsulation layer 24. The thickness design of the organic layer 242 cooperates with the microlens array layer 23 and the color filter film 22 to achieve the effect of both high light extraction efficiency and anti-peep screen design.

[0041] In some embodiments, the display panel 20 further includes a touch sensing layer 25, which is disposed between the microlens array layer 23 and the color filter film 22. The touch sensing layer 25 is provided with touch electrodes 251 to implement touch sensing functionality. When the display panel 20 is provided with the touch sensing layer 25, the display panel 20 is a touch-sensitive display device. In some embodiments, the touch electrodes 251 in the touch sensing layer 25 are arranged corresponding to the black matrix 221 of the color filter film 22. The black matrix 221 shields the touch electrodes 251, eliminating the need for an additional shielding structure. This helps reduce the thickness of the display panel 20 and improves the display quality of the display panel 20.

[0042] In some embodiments, the display panel 20 further includes a substrate 26, a buffer layer 27, and a planarization layer 28, which are disposed on the side of the pixel definition layer 21 facing away from the encapsulation layer 24. The substrate 26, the buffer layer 27, and the planarization layer 28 are stacked in sequence in the direction from the substrate 26 to the pixel definition layer 21. The material of the substrate 26 includes, but is not limited to, polyimide (PI), the material of the buffer layer 27 includes, but is not limited to, silicon nitride (SiNx), silicon oxide (SiOx), or silicon oxynitride (SiOxNx), and the material of the planarization layer 28 includes, but is not limited to, any suitable organic resin material. In some embodiments, the display panel 20 further includes an optical adhesive layer 29 and a cover layer 31, which are disposed on the side of the color filter film 22 facing away from the encapsulation layer 24. The optical adhesive layer 29 bonds the cover layer 31 to the color filter film 22. The cover layer 31 may include a glass layer 311 provided on the optical adhesive layer 29 and a surface layer 312 provided on the glass layer 311. The material of the glass layer 311 includes but is not limited to UTG glass, and the material of the surface layer 312 includes but is not limited to organic materials such as polyethylene terephthalate (PET). Of course, the cover layer 31 may also have any other applicable settings, as long as the strength and light transmittance requirements can be met. The display panel 20 may also include any other applicable components, and the above-mentioned components may also be replaced by other components, as long as the corresponding functions can be achieved, which will not be described in detail in this application. It can be understood that when the display panel 20 is provided with a cover layer 31, the surface of the cover layer 31 facing away from the color filter film 22 can be regarded as the light-emitting surface of the display panel 20, and the surface of the light-emitting unit 211 facing the cover layer 31 can be regarded as the light-emitting surface of the light-emitting unit 211.

[0043] Referring to Figure 4, Figure 4 is a schematic diagram of the structure of an electronic device 10 provided in an embodiment of the present application. The electronic device 10 may include a radio frequency (RF) circuit 501, a memory 502 including one or more computer-readable storage media, an input unit 503, a display unit 504, a sensor 505, an audio circuit 506, a wireless fidelity (WiFi) module 507, a processor 508 including one or more processing cores, and a power supply 509. It will be understood by those skilled in the art that the structure of the electronic device 10 shown in Figure 4 does not constitute a limitation on the electronic device 10, and may include more or fewer components than shown, or combine certain components, or arrange the components differently.

[0044] The radio frequency circuit 501 can be used to send and receive information, or receive and send signals during a call. In particular, after receiving downlink information from the base station, it is handed over to one or more processors 508 for processing; in addition, uplink data is sent to the base station. Generally, the radio frequency circuit 501 includes but is not limited to an antenna, at least one amplifier, a tuner, one or more oscillators, a subscriber identity module (SIM) card, a transceiver, a coupler, a low noise amplifier (LNA), a duplexer, etc. In addition, the radio frequency circuit 501 can also communicate with the network and other devices through wireless communication. The wireless communication can use any communication standard or protocol, including but not limited to Global System of Mobile Communications (GSM), General Packet Radio Service (GPRS), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA), Long Term Evolution (LTE), email, Short Messaging Service (SMS), etc.

[0045] The memory 502 can be used to store applications and data. The applications stored in the memory 502 include executable code. The applications can be composed of various functional modules. The processor 508 executes various functional applications and data processing by running the applications stored in the memory 502. The memory 502 may mainly include a program storage area and a data storage area, wherein the program storage area may store an operating system, applications required for at least one function (such as a sound playback function, an image playback function, etc.), etc.; the data storage area may store data created based on the use of the electronic device 10 (such as audio data, a phone book, etc.), etc. In addition, the memory 502 may include a high-speed random access memory, and may also include a non-volatile memory, such as at least one disk storage device, a flash memory device, or other volatile solid-state storage device. Accordingly, the memory 502 may also include a memory controller to provide the processor 508 and the input unit 503 with access to the memory 502.

[0046] The input unit 503 can be used to receive input digital, character information or user feature information (such as fingerprints), and generate keyboard, mouse, joystick, optical or trackball signal input related to user settings and function control. Specifically, in a specific embodiment, the input unit 503 may include a touch-sensitive surface and other input devices. The touch-sensitive surface, also known as a touch display or touchpad, can collect user touch operations on or near it (such as operations performed by the user using a finger, stylus or any other suitable object or accessory on or near the touch-sensitive surface) and drive the corresponding connection device according to a pre-set program. Optionally, the touch-sensitive surface may include two parts: a touch detection device and a touch controller. The touch detection device detects the user's touch direction and detects the signal generated by the touch operation, and transmits the signal to the touch controller; the touch controller receives the touch information from the touch detection device, converts it into touch point coordinates, and then sends it to the processor 508. It can also receive commands sent by the processor 508 and execute them.

[0047] The display unit 504 can be used to display information input by the user or information provided to the user, as well as various graphical user interfaces of the electronic device 10. These graphical user interfaces can be composed of graphics, text, icons, videos, and any combination thereof. The display unit 504 may include a display panel. Optionally, the display panel can be configured in the form of a liquid crystal display (LCD), an organic light-emitting diode (OLED), or the like. Furthermore, a touch-sensitive surface can cover the display panel. When the touch-sensitive surface detects a touch operation on or near it, it transmits the information to the processor 508 to determine the type of touch event. The processor 508 then provides a corresponding visual output on the display panel based on the type of touch event. Although in Figure 4, the touch-sensitive surface and the display panel are implemented as two independent components to implement input and output functions, in some embodiments, the touch-sensitive surface and the display panel can be integrated to implement input and output functions.
