[0002] With the continuous development of technology, full-screen technology is an important innovation in the display field of electronic devices such as mobile phones and tablets.

[0075] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings.

The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of structures consistent with some aspects of this disclosure as detailed in the appended claims.

Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

[0078] The technical solutions provided by the various embodiments of this disclosure are described in detail below with reference to the accompanying drawings.

[0079] Figure 1 This is a schematic diagram of the structure of a display panel according to an exemplary embodiment. Figure 1 , Figure 2 This is a schematic diagram of the structure of a display panel according to an exemplary embodiment. Figure 2 ,like Figure 1 and Figure 2 As shown, the display panel 10 may include:

[0080] Base 11;

[0081] Touch layer 12 is located on substrate 11;

[0082] The light-emitting layer 13 is stacked between the substrate 11 and the touch layer 12, and includes a plurality of pixel units 131 and a gap region 132 between any two pixel units 131;

[0083] A light-concentrating structure 14 is disposed on the substrate 11 along the stacking direction of the light-emitting layer 13 and is disposed opposite to the gap region 132. It is used to converge ambient light passing through the gap region 132 or to converge ambient light to the gap region 132.

[0084] In this embodiment of the disclosure, the display panel can be an organic light-emitting diode (OLED) panel; wherein, the OLED display panel may include, but is not limited to: an active matrix organic light-emitting diode (AMOLED) panel or a passive matrix organic light-emitting diode (PMOLED) panel, etc.

[0085] It should be noted that the specific type of display panel can be selected according to the actual application, and this disclosure does not impose any limitations. For example, the above-mentioned display panel can be a mobile phone display panel, a watch display panel, a tablet computer display panel, etc.

[0086] The display panel proposed in this disclosure can be applied to various display fields with OLED full-screen displays to improve the problem of simultaneously achieving high image quality and high screen quality in OLED full-screen displays. For example, such as... Figure 3a and Figure 3b As shown, the display panels described above can be applied to display fields such as full-screen applications for mobile phones and tablets, and application scenarios can include mainstream user needs such as audio-visual entertainment, office work, and games.

[0087] The aforementioned substrate can be a substrate structure at the bottom of the display panel, used to support other upper structures in the display panel.

[0088] It should be noted that the substrate can be an insulating substrate made of glass, quartz, transparent plastic, etc., or a metal substrate made of stainless steel, etc.; wherein, the transparent plastic substrate can be formed from any one of polyimide (PI) resin, acrylic resin, polyacrylate resin, polycarbonate (PC) resin or polyether resin, and the embodiments disclosed herein are not limited thereto.

[0089] Here, the aforementioned touch layer can be a functional layer in the display panel responsible for sensing user touch commands; the touch layer can include touch electrodes and touch traces connecting the touch electrodes and the driver chip, and can convert touch signals into electrical signals by sensing changes in capacitance or resistance when touched by an object (such as a finger or stylus), and transmit them to the driver chip to calculate the touch position in order to realize touch interaction.

[0090] It should be noted that an opening may be provided in the position opposite to the gap area between the pixel units in the touch layer, or the electrodes and traces in the touch layer opposite to the gap area may be made of transparent material.

[0091] In this embodiment of the disclosure, the light-emitting layer can be a functional layer in the display panel that is responsible for converting electrical energy into light energy, and is the light source basis for forming an image; under the control of the driving circuit, the light-emitting layer can emit light of different brightness and color through electroluminescence effect to form a display image.

[0092] The aforementioned pixel units can be the smallest light-emitting units in the light-emitting layer of the display panel that can independently control brightness and color, and are the basic pixel units for forming an image; each pixel unit may include at least one of the three sub-pixels: red, green, and blue.

[0093] Here, the gap between any two pixel units in the light-emitting layer can be a pixel definition layer (PDL), which can be used to separate adjacent pixel units and prevent light crosstalk and color mixing of organic materials. The gap area in this disclosure can allow ambient light to pass through so that it can be transmitted to the camera under the display panel, thereby realizing the full-screen technology of the display panel.

[0094] In this embodiment of the present disclosure, the light-concentrating structure can cause light to propagate in a predetermined direction through refraction, that is, to focus the light in a predetermined direction; the light-concentrating structure in this disclosure can focus ambient light passing through the gap region on the light-emitting layer or focus ambient light into the gap region.

[0095] Here, the relative arrangement of the aforementioned focusing structure and the aforementioned gap region can be understood as follows: the orthographic projection of the focusing structure onto the substrate overlaps with the orthographic projection of the gap region onto the substrate; for example, the orthographic projection of the focusing structure onto the substrate may completely or partially overlap with the orthographic projection of the gap region onto the substrate. Specifically, the complete overlap between the orthographic projection of the focusing structure onto the substrate and the orthographic projection of the gap region onto the substrate may include: the size of the orthographic projection of the focusing structure onto the substrate being less than or equal to the size of the orthographic projection of the gap region onto the substrate.

[0096] Understandably, taking an electronic device with an under-display camera as an example, the substrate of the display panel has a light-transmitting area for transmitting ambient light to the under-display camera. In this case, the touch layer has an opening at a position opposite to this light-transmitting area, or the electrodes and traces of the touch layer at this position are made of transparent materials. That is, ambient light outside the display panel can be transmitted to the under-display camera through the light-concentrating structure, the opening or transparent material of the touch layer, the gap area of ​​the light-emitting layer, and the light-transmitting area; or, ambient light outside the display panel can also be transmitted to the under-display camera through the opening or transparent material of the touch layer, the gap area of ​​the light-emitting layer, the light-concentrating structure, and the light-transmitting area.

[0097] It should be noted that the specific position of the light-concentrating structure on the substrate can be set according to the actual application scenario, as long as the light-concentrating structure is relatively positioned relative to the gap area on the light-emitting layer. This embodiment does not impose any restrictions.

[0098] For example, when the display panel is a screen with a polarizer, the light-concentrating structure can be stacked on the side of the touch layer away from the substrate, or stacked between the substrate and the light-emitting layer; when the display panel is a screen with a depolarizer, the display panel may include a filter layer stacked on the side of the touch layer away from the substrate, and the light-concentrating structure can be stacked on the side of the filter layer away from the substrate, etc.

[0099] In some embodiments, the light-concentrating structure includes an organic film layer. Thus, the fluidity and plasticity of the organic film layer allow for the precise fabrication of the light-concentrating structure required for the display panel using a low-cost process, thereby improving the processing flexibility of the light-concentrating structure and reducing the production cost of the display panel.

[0100] Here, the organic film layer can be a film layer formed by imprinting or injection molding of organic materials; for example, the light-concentrating structure can include, but is not limited to, organic film layers such as a protective layer, a passivation layer, or a planarization layer.

[0101] In some embodiments, the organic film layer includes a protective layer, a passivation layer, or a planarization layer.

[0102] The aforementioned overcoat layer (OC) can be a structure formed of organic insulating material, used to protect the underlying film layer and functional devices, preventing them from being affected by external environmental factors (such as moisture, oxygen, dust, etc.) and thus causing performance degradation or damage. It can also play a role in buffering and wear resistance, improving the reliability and service life of the entire display panel.

[0103] The aforementioned passivation layer (PAS) can be made of materials with good chemical stability and insulation properties. The function of the passivation layer is to passivate the surface of the light-concentrating structure, reduce surface defects and dangling bonds, and reduce surface state density, thereby improving the electrical performance and stability of the display panel.

[0104] The planarization layer (PLN) mentioned above can be a polymer layer, formed using materials such as polyacrylate and parylene. The planarization layer can be used to fill in the unevenness of the substrate surface, making the surface smooth. In display panel manufacturing, subsequent film deposition and device fabrication require a high degree of substrate surface smoothness. The planarization layer can provide a smooth surface for subsequent processes, which is beneficial for improving the uniformity of the film and the consistency of device performance.

[0105] It should be noted that the focusing structure is usually formed by OC, and the specific type of focusing structure can be set according to the actual application scenario. This disclosure does not limit it.

[0106] In some embodiments, the light-concentrating structure includes a microprism structure. Thus, the microprism structure allows for more precise focusing of ambient light, further improving the light transmittance of the display panel and effectively increasing the amount of light entering the electronic device where the display panel is located for photography.

[0107] Here, a microprism structure is an optical structure with tiny dimensions. It is usually based on triangular or trapezoidal cross-sections as basic units, which are periodically arranged on a substrate to form a surface structure with specific optical functions. The surface and angle of the microprism structure are precisely designed and processed to meet the requirements of precise light path deflection, so that light can propagate in a predetermined direction.

[0108] It should be noted that the specific material of the microprism structure can be set according to the actual application scenario, and this disclosure does not impose any limitations. For example, the microprism structure can be made of materials such as polyethylene terephthalate (PET), polycarbonate, or glass, and prepared using a UV-curing resin molding process.

[0109] In some embodiments, the light-gathering structure is hemispherical, ellipsoidal, or conical in shape, thereby enhancing the design diversity of the light-gathering structure in the display panel.

[0110] It should be noted that the specific shape of the microprism structure can also be set according to the actual application scenario, and this disclosure does not impose any limitations. For example, the shape of the microprism structure can be hemispherical, ellipsoidal, or conical, etc.

[0111] In some embodiments, the size of the orthographic projection of the light-concentrating structure onto the substrate is smaller than the size of the orthographic projection of the gap region onto the substrate.

[0112] In this way, by setting the size of the orthogonal projection of the light-concentrating structure onto the substrate to be smaller than the size of the orthogonal projection of the gap area on the light-emitting layer onto the substrate, the light transmittance of the display panel can be effectively improved without affecting the display effect of the display panel.

[0113] Here, the size of the orthographic projection of the light-concentrating structure onto the substrate being smaller than the size of the orthographic projection of the gap region onto the substrate may include, but is not limited to: the area of ​​the orthographic projection of the light-concentrating structure onto the substrate being smaller than the area of ​​the orthographic projection of the gap region onto the substrate; or, the length of the orthographic projection of the light-concentrating structure onto the substrate in the direction parallel to the substrate may be smaller than the length of the orthographic projection of the gap region onto the substrate in the direction parallel to the substrate, etc.

[0114] For example, the period of the pixel unit of the light-emitting layer is 20 micrometers, that is, the length of the orthogonal projection of the above-mentioned gap region onto the substrate in the direction parallel to the substrate is 20 micrometers; at this time, the length of the orthogonal projection of the light-concentrating structure onto the substrate in the direction parallel to the substrate can be less than 20 micrometers, for example, 15 micrometers, 17 micrometers or 19 micrometers, etc.

[0115] In some embodiments, such as Figure 2As shown, there are multiple light-concentrating structures 14; one light-concentrating structure 14 is arranged opposite to a gap region 132; the size of the orthographic projection of each light-concentrating structure 14 onto the substrate 11 is smaller than the size of the orthographic projection of the corresponding gap region 132 onto the substrate 11.

[0116] In this way, by setting the size of the orthographic projection of each of the multiple light-concentrating structures onto the substrate to be smaller than the size of the orthographic projection of the corresponding gap region onto the substrate, it is possible to further improve the light transmittance of the display panel while ensuring the display effect of the display panel.

[0117] In this embodiment, the number of light-concentrating structures can be the same as the number of gap regions on the light-emitting layer, and the size of the orthographic projection of each light-concentrating structure onto the substrate is smaller than the size of the orthographic projection of the corresponding gap region onto the substrate. That is, the area of ​​the orthographic projection of each light-concentrating structure onto the substrate is smaller than the area of ​​the orthographic projection of the corresponding gap region onto the substrate; or, the length of the orthographic projection of each light-concentrating structure onto the substrate in the direction parallel to the substrate is smaller than the length of the orthographic projection of the corresponding gap region onto the substrate in the direction parallel to the substrate, etc.

[0118] It should be noted that the specific number of light-concentrating structures can be set according to the size of the light-transmitting area required by the display panel in the actual application scenario, as long as the number of gap areas in the light-transmitting area is the same as the number of light-concentrating structures. This disclosed embodiment does not impose any restrictions.

[0119] In current full-screen technologies, there is a trade-off between image quality and screen quality in the CPU area. Specifically, higher display quality in the CPU area results in lower screen transmittance, thus degrading the image quality of the under-display camera; conversely, achieving high transmittance in the CPU area requires sacrificing display quality in that area. Therefore, improving the transmittance of the CPU area is a pressing issue that needs to be addressed in this field.

[0120] In view of this, such as Figure 4a and Figure 4b As shown, the traditional display panel 20 improves its light transmittance to the greatest extent by reducing the pixel density of the under-display camera area 21, designing the pixel units in the under-display camera area 21 as islands (i.e., increasing the spacing between two adjacent pixel units), and placing the array circuit 22 below the island-shaped pixel units.

[0121] However, this approach of designing the pixel units in the CUP area as islands still sacrifices some of the display effect of the CUP area to improve the photo quality of the under-display camera. The CUP area still faces the problem of not being able to balance screen display effect and photo quality.

[0122] Based on this, the present disclosure provides a display panel, which includes: a substrate; a touch layer located on the substrate; a light-emitting layer stacked between the substrate and the touch layer, and including a plurality of pixel units and a gap region between any two pixel units; and a light-concentrating structure disposed on the substrate along the stacking direction of the light-emitting layer and disposed opposite to the gap region, for converging ambient light passing through the gap region or converging ambient light to the gap region.

[0123] In this way, by adding a light-concentrating structure on the substrate of the display panel along the stacking direction of the light-emitting layer, and setting the position of the light-concentrating structure opposite to the gap area between any two pixel units in the multiple pixel units of the light-emitting layer, it is possible to converge ambient light passing through the gap area or to converge ambient light to the gap area, so as not to affect the normal display of the pixel units in the display panel, thereby improving the light transmittance of the display panel while ensuring the display quality of the display panel.

[0124] In some optional embodiments, taking an electronic device with an under-display camera as an example, this disclosure can stack a light-gathering structure on the substrate of the display panel, which is opposite to both the gap area and the under-display camera. This can gather ambient light passing through the gap area or gather ambient light into the gap area, so as not to affect the normal display of the pixel units in the display panel. This can improve the light transmittance of the display panel while ensuring the display quality of the display panel, thereby increasing the amount of light entering the under-display camera in the electronic device and improving the photo quality of the electronic device.

[0125] In some embodiments, such as Figure 2 As shown, the light-concentrating structure 14 is stacked on the side of the touch layer 12 away from the substrate 11;

[0126] Ambient light is transmitted to the gap region 132 via the light-concentrating structure 14 and the touch layer 12;

[0127] The light emitted by the light-emitting layer 13 is transmitted to the outside of the display panel 10 via the touch layer 12 and the light-concentrating structure 14.

[0128] In this way, by stacking the light-concentrating structure on the side of the touch layer away from the substrate, ambient light can be transmitted to the gap area on the light-emitting layer through the light-concentrating structure and the touch layer, while the light emitted by the light-emitting layer can be transmitted to the outside of the display panel through the touch layer and the light-concentrating structure. This allows for better adaptation to display panels with polarizers and improves the flexibility of setting the position of the light-concentrating structure in the display panel.

[0129] In this embodiment of the present disclosure, when the display panel is a screen with a polarizer, the light-concentrating structure can be stacked on the side of the touch layer away from the substrate; at this time, the polarizer can be stacked on the side of the touch layer away from the substrate, and the light-concentrating structure can be stacked between the touch layer and the polarizer.

[0130] For example, such as Figure 2 As shown, when the display panel 10 is a screen with a polarizer L1, and the light-concentrating structure 14 is stacked between the touch layer 12 and the polarizer L1, the path of ambient light outside the display panel 10 can be polarizer L1 - light-concentrating structure 14 - opening or transparent material of touch layer 12 - gap area 132 on the light-emitting layer - light-transmitting area of ​​substrate 11 - under-screen camera; similarly, the path of light emitted from the light-emitting layer can be pixel unit 131 of the light-emitting layer - touch layer 12 - light-concentrating structure 14 - polarizer L1 - outside the display panel 10.

[0131] In some embodiments, such as Figure 2 and Figure 5a As shown, the light-concentrating structure 14 is stacked between the substrate 11 and the light-emitting layer 13;

[0132] Ambient light is transmitted to the light-concentrating structure 14 via the touch layer 12 and the gap region 132;

[0133] The light emitted by the light-emitting layer 13 is transmitted to the outside of the display panel 10 via the touch layer 12.

[0134] In this way, by stacking the light-concentrating structure between the substrate and the light-emitting layer, and by transmitting ambient light to the light-concentrating structure through the gap area on the touch layer and the light-emitting layer, while the light emitted by the light-emitting layer can be transmitted to the outside of the display panel through the touch layer, the flexibility of setting the position of the light-concentrating structure in the display panel can be effectively improved while adapting to display panels with polarizers.

[0135] In this embodiment of the disclosure, when the display panel is a screen with a polarizer, the light-gathering structure can be stacked between the substrate and the light-emitting layer; at this time, the polarizer can be stacked on the side of the touch layer away from the substrate.

[0136] For example, in combination Figure 2 and Figure 5a When the display panel 10 is a screen with a polarizer L1 and the light-concentrating structure 14 is stacked between the substrate 11 and the light-emitting layer 13, the path of ambient light outside the display panel 10 can be polarizer L1 - opening or transparent material of touch layer 12 - gap area 132 of light-emitting layer - light-concentrating structure 14 - light-transmitting area of ​​substrate 11 - under-screen camera; similarly, the path of light emitted by the light-emitting layer can be pixel unit 131 of light-emitting layer - touch layer 12 - polarizer L1 - outside the display panel 10.

[0137] In some embodiments, such as Figure 5b and Figure 5c As shown, the above-mentioned display panel 10 also includes:

[0138] The filter layer 15 includes a filter portion 151 and a light-shielding portion 152, and is stacked on the side of the touch layer 12 away from the substrate 11.

[0139] The filter unit 151 is disposed opposite to the plurality of pixel units 131;

[0140] The light-shielding part 152 is disposed opposite to the gap region 132 and is provided with a first opening 153;

[0141] The light-concentrating structure 14 is stacked on the side of the filter layer 15 away from the substrate 11 and is disposed opposite to the first opening 153.

[0142] Thus, in a display panel having a filter layer stacked on the side of the touch layer away from the substrate, by stacking a light-concentrating structure on the side of the filter layer away from the substrate and setting the light-concentrating structure opposite to the first opening on the light-shielding part of the filter layer, it is possible to better adapt to a display panel with a depolarizer but a filter layer, and further improve the flexibility of setting the position of the light-concentrating structure in the display panel.

[0143] In this embodiment of the present disclosure, when the display panel is a screen with a depolarizer, the display panel may include a filter layer stacked on the side of the touch layer away from the substrate; the filter layer may include a filter portion disposed opposite to the pixel unit of the light-emitting layer and a light-shielding portion disposed opposite to the gap region of the light-emitting layer, and the light-shielding portion is provided with a first opening; at this time, the light-concentrating structure may be stacked on the side of the filter layer away from the substrate and disposed opposite to the first opening on the light-shielding portion.

[0144] Here, the aforementioned filter layer can be a structure used to replace the function of the polarizer after the polarizer is removed from the display panel; the filter layer may include, but is not limited to, a filter part and a light-shielding part, which can filter the incident stray light while preventing light leakage through the gap area on the light-emitting layer, thereby improving the light utilization rate.

[0145] The aforementioned filter unit can be a functional unit in the filter layer of the display panel responsible for precise light filtering and generating three primary colors; for example, the filter unit can be a color resist, each color resist corresponding to a sub-pixel of a pixel unit. By filtering specific wavelengths of light, the display panel can display red (R), green (G), and blue (B) colors, thereby mixing to produce a full-color image.

[0146] The aforementioned light-shielding part can be a grid-like structure in the filter layer of the display panel, which can be used to define the boundaries of pixel units and prevent light leakage and color mixing between pixel units. For example, the light-shielding part can be a black matrix (BM), which is a light-shielding material located in the non-effective display area of ​​the display panel. It can prevent light leakage between pixel units and block light from overflowing from the edge of the display area, thereby improving the contrast and visual effect of the displayed image. It can also be used to wrap the wiring in the display panel to prevent the wiring from affecting the display effect.

[0147] It is understood that the aforementioned filter layer can be fabricated using the same device, meaning that the filtering portion and the light-shielding portion are two different parts of the filter layer fabricated using the same device. Alternatively, the filter layer can also be composed of different components, meaning that the filtering portion and the light-shielding portion are two separate components constituting the filter layer; for example, the filter layer may include color resist and BM.

[0148] It should be noted that when the display panel has a CUP area, the first opening provided on the light-shielding part is located within the CUP area; and the specific number of the first openings on the light-shielding part can be set according to the number of light-gathering structures in the actual application scenario, that is, the number of the first openings on the light-shielding part can be the same as the number of light-gathering structures, and this embodiment does not impose any restrictions.

[0149] In some embodiments, such as Figure 5c As shown, ambient light is transmitted to the gap region 132 via the light-concentrating structure 14, the first opening 153 and the touch layer 12;

[0150] The light emitted by the light-emitting layer 13 is transmitted to the outside of the display panel 10 via the touch layer 12, the filter 151 and the light-concentrating structure 14.

[0151] In this way, ambient light can be transmitted to the gap area through the light-concentrating structure, the first opening and the touch layer, while the light emitted by the light-emitting layer can be transmitted to the outside of the display panel through the touch layer, the filter and the light-concentrating structure, thereby improving the light transmittance of the display panel.

[0152] For example, such as Figure 5c As shown, when the display panel 10 is a screen with a depolarizer and the light-concentrating structure 14 is stacked on the side of the filter layer 15 away from the substrate 11, the path of ambient light outside the display panel 10 can be: light-concentrating structure 14 - first opening 153 on the filter layer 15 - opening or transparent material of the touch layer 12 - gap area 132 on the light-emitting layer - light-transmitting area of ​​the substrate 11 - under-display camera; similarly, the path of light emitted from the light-emitting layer can be: pixel unit 131 of the light-emitting layer - touch layer 12 - filter part 151 on the filter layer 15 - light-concentrating structure 14 - outside the display panel 10.

[0153] In some embodiments, see Figure 1 , Figure 2 as well as Figures 6a-6b The arrangement of multiple sub-pixels 133 in each pixel unit 131 of the light-emitting layer 13 is different, and the arrangement position of the corresponding light-gathering structure 14 is different.

[0154] In this way, when the arrangement of multiple sub-pixels in each pixel unit of the light-emitting layer is different, light-concentrating structures with different arrangement positions can be set to improve the light transmittance of display panels with various pixel arrangements and enhance the user experience.

[0155] Here, the arrangement of multiple subpixels in each pixel unit of the luminescent layer can include, but is not limited to: real RGB pixel arrangement, subpixel rendering (SPR) pixel arrangement, or jagged pixel arrangement, etc.

[0156] In some embodiments, such as Figure 1 and Figure 6a As shown, when multiple sub-pixels 133 are arranged in the first arrangement, the orthogonal projection of the light-concentrating structure 14 onto the light-emitting layer 13 is located in the gap between any two sub-pixels 133 among the multiple sub-pixels 133.

[0157] Among them, the multiple sub-pixels 133 include a first color sub-pixel, a second color sub-pixel and a third color sub-pixel, and the first arrangement method is that the first color sub-pixel, the second color sub-pixel and the third color sub-pixel are arranged in a preset order.

[0158] In this way, when multiple sub-pixels are arranged in the first arrangement, the orthogonal projection of the light-collecting structure onto the light-emitting layer can be set on the gap between any two sub-pixels, thereby improving the light transmittance of the display panel with uniformly distributed pixel arrangement.

[0159] In this embodiment of the disclosure, the multiple sub-pixels in each pixel unit of the light-emitting layer are arranged in a first arrangement, which can be a real RGB pixel arrangement, and can adopt a pixel structure with a complete RGB sub-pixel arrangement. That is, the multiple sub-pixels in each pixel unit can be composed of a first color sub-pixel, a second color sub-pixel, and a third color sub-pixel, that is, composed of standard red (R), green (G), and blue (B) three primary color sub-pixels, and each sub-pixel can emit light independently.

[0160] Here, the preset order can be the arrangement order of each color sub-pixel in the real RGB pixel arrangement; for example, the preset order can be a strip arrangement order, that is, the red, green and blue color sub-pixels are arranged in the horizontal direction, each pixel unit contains complete three primary color sub-pixels, and the preset order in each pixel unit is the same.

[0161] For example, when the display panel is a screen with a depolarized film, such as Figure 6a As shown, each pixel unit contains multiple sub-pixels 133 (i.e., R pixels, G pixels, and B pixels) arranged in real RGB pixel configuration. Furthermore, in the direction of the light-collecting structure 14 (i.e., the microprism) projecting onto the light-emitting layer, each sub-pixel 133 is surrounded by a light-shielding portion 152 (i.e., a BM ring). The blank area between the light-shielding portions 152 is the first opening provided on the light-shielding portion 152. At this time, the light-collecting structure 14 is positioned opposite to the first opening, and the projected light-collecting structure 14 onto the light-emitting layer is located in the gap between any two sub-pixels 133.

[0162] In some embodiments, such as Figure 1 , Figure 6b and Figure 6c As shown, when multiple sub-pixels 133 are arranged in the second arrangement, the orthogonal projection of the light-concentrating structure 14 onto the light-emitting layer 13 is located in the gap between two adjacent sub-pixels 133 among the multiple sub-pixels 133.

[0163] Among them, the multiple sub-pixels 133 include at least two color sub-pixels, and the second arrangement is that the arrangement order of at least two color sub-pixels in two adjacent pixel units 131 is different.

[0164] In this way, when multiple sub-pixels are arranged in the second arrangement, the orthogonal projection of the light-collecting structure onto the light-emitting layer can be set in the gap between two adjacent sub-pixels, thereby improving the light transmittance of the display panel with pixels arranged in a cross distribution.

[0165] In this embodiment of the disclosure, the arrangement of multiple sub-pixels in each pixel unit of the light-emitting layer in a second arrangement can be called SPR pixel arrangement. By optimizing the layout and rendering method of sub-pixels, the visual resolution of the display panel under limited physical pixels can be improved. Among them, SPR pixel arrangement usually changes the traditional RGB strip arrangement. For example, the PenTile arrangement uses different combination modes of red, green and blue sub-pixels, or in some cases, some sub-pixels are omitted to reduce the total number of sub-pixels.

[0166] Here, each pixel unit arranged in the second arrangement includes at least two color sub-pixels, that is, the number of color sub-pixels in the pixel units arranged in the second arrangement can be different; for example, the sub-pixels in the first pixel unit include a first color sub-pixel and a second color sub-pixel, while the sub-pixels in the second pixel unit adjacent to the first pixel unit include a first color sub-pixel, a second color sub-pixel, and a third color sub-pixel.

[0167] It is understandable that, taking the second arrangement method, SPR pixel arrangement, as an example, adjacent pixel units in the SPR pixel arrangement can share sub-pixels. That is, the number of green sub-pixels in the SPR pixel arrangement is the same as the number of pixel units, while the number of red and blue sub-pixels can be half the number of standard RGB sub-pixels. In this case, the arrangement order of sub-pixels in two adjacent pixel units in the SPR pixel arrangement is different so that they can share sub-pixels. For example, when the display panel is a screen with a polarizer, such as... Figure 6b As shown, the multiple sub-pixels 133 (i.e., R pixels, G pixels, and B pixels) in each pixel unit are arranged in SPR pixel configuration. Furthermore, in the forward projection direction of the light-collecting structure 14 (i.e., microprism) onto the light-emitting layer, the light-collecting structure 14 is located in the gap between two adjacent sub-pixels 133 among the multiple sub-pixels 133.

[0168] Similarly, when the display panel is a screen with a depolarized filter, such as Figure 6c As shown, the multiple sub-pixels 133 (i.e., R pixels, G pixels, and B pixels) in each pixel unit are arranged in SPR pixel configuration. Furthermore, in the direction of the light-collecting structure 14 (i.e., the microprism) projecting onto the light-emitting layer, each sub-pixel 133 is surrounded by a light-shielding portion 152 (i.e., a BM ring), and the blank area between the light-shielding portions 152 is the first opening provided on the light-shielding portion 152. At this time, the light-collecting structure 14 is positioned opposite to the first opening, and the projected light-collecting structure 14 onto the light-emitting layer is located in the gap between two adjacent sub-pixels 133.

[0169] In some embodiments, such as Figure 1 and Figure 7a As shown, the substrate 11 includes a first region 111 for light transmission;

[0170] The orthographic projection of the light-concentrating structure 14 onto the substrate 11 is located within the first region 111.

[0171] In this way, by projecting the light-concentrating structure onto the substrate and placing it in the first area of ​​the substrate for light transmission, the light transmittance of the first area of ​​the display panel can be further improved, effectively enhancing the light utilization rate of the device located below the first area of ​​the display panel.

[0172] Here, the first area can be the base of the display panel for light transmission, and can be made of transparent material; for example, the first area can be the CUP area of ​​the display panel, that is, an under-display camera is set below the first area of ​​the display panel.

[0173] It is understood that by projecting the light-concentrating structure onto the substrate and placing it in the first region, the present disclosure can concentrate the ambient light incident on the display panel into the first region, thereby increasing the amount of light entering the first region and improving the light transmittance of the display panel in the corresponding first region.

[0174] In some embodiments, such as Figure 1 , Figure 5a , Figure 7b and Figure 7c As shown, the substrate 11 also includes a second region 112 disposed adjacent to the first region 111; the touch layer 12 includes:

[0175] The second opening 121 is disposed opposite to the first region 111;

[0176] Barrier section (in) Figure 7b and Figure 7c (Not shown in the middle), disposed around the second opening 121;

[0177] Touch unit (in) Figure 7b and Figure 7c (Not shown in the middle), is disposed on the side of the barrier portion away from the second opening 121, and is disposed opposite to the second region 112.

[0178] In this way, by setting a second opening on the touch layer opposite to the first area, and setting the touch part in the touch layer opposite to the second area, and setting a blocking part to isolate the touch part and the second opening, the light transmittance of the display panel corresponding to the first area can be improved without affecting the touch function of the second area of ​​the display panel.

[0179] Here, the second region can be a region in the substrate that is positioned opposite to the area on the display panel used for displaying images. The second opening can be an opening on the touch layer that is positioned opposite to the first region, and the orthographic projection of the second opening onto the substrate can be located within the first region.

[0180] In this embodiment, the aforementioned barrier portion can be an insulating separation structure located in the touch layer between the touch portion and the second opening assembly. On one hand, the barrier portion can separate the second opening area from the touch portion, preventing the conductive material of the touch portion from extending into the second opening area and affecting the light transmission effect; on the other hand, the barrier portion can protect the touch portion structure at the edge of the second opening, avoiding material overflow or structural damage during subsequent processes (such as bonding and encapsulation).

[0181] It is understandable that the aforementioned touch unit can be the core structure in the touch layer responsible for sensing touch signals, and is the basis for realizing touch functions; for example, the touch unit may include touch electrodes distributed in an array and touch traces connecting the touch electrodes and the driver chip, etc.

[0182] It should be noted that the orthographic projections of the aforementioned barrier portion and touch portion onto the substrate can both be located within the second region of the substrate to avoid affecting the light transmission effect of the display panel.

[0183] In some embodiments, the touch layer disposed opposite to the first region is made of a transparent material.

[0184] In this way, by setting the material of the touch layer opposite to the first area to be transparent, the light transmittance of the display panel corresponding to the first area can be effectively improved without affecting the touch function of the second area of ​​the display panel.

[0185] Here, the touch layer positioned opposite the first region may include at least: touch electrodes and touch traces projected onto the first region. The aforementioned transparent material may include, but is not limited to: indium tin oxide (ITO), silver nanowires, or graphene.

[0186] It should be noted that the material of the touch layer disposed opposite to the second region can be a conventional touch material; for example, the material of the touch layer disposed opposite to the second region can include, but is not limited to, conductive metallic materials such as copper, aluminum or silver.

[0187] In some embodiments, such as Figure 1 , Figure 5a and Figure 5b As shown, the above-mentioned display panel 10 also includes:

[0188] A driving circuit layer 16 is stacked between the substrate 11 and the light-emitting layer 13;

[0189] In the driving circuit layer 16, the traces that are disposed opposite to the first region 111 are transparent traces, or are disposed around the first region 111.

[0190] In this way, by stacking a driving circuit layer between the substrate and the light-emitting layer, and making the traces in the driving circuit layer that are opposite to the first area transparent or surrounding the first area, the light transmittance of the display panel corresponding to the first area can be effectively improved without affecting the touch function and display effect of the display panel.

[0191] Here, the aforementioned driving circuit layer can be the core functional layer in the display panel that realizes the conversion between electrical signals and optical signals, and is responsible for receiving external control signals and accurately addressing and driving the pixel units of the light-emitting layer.

[0192] It should be noted that the specific material of the transparent trace positioned opposite the first region in the driving circuit layer can be set according to the actual application scenario. For example, the material of the transparent trace can include, but is not limited to, ITO or silver nanowires.

[0193] In some embodiments, such as Figure 1 , Figure 5a and Figure 5b As shown, the display panel 10 also includes:

[0194] The ink layer 17 covers the light-concentrating structure 14 and is used to absorb stray light passing through the light-concentrating structure 14.

[0195] In this way, by setting an ink layer on the light-concentrating structure, stray light passing through the light-concentrating structure can be absorbed, thereby increasing the refractive index of the light-concentrating structure and further improving the light utilization rate of the display panel.

[0196] Here, the ink layer can be an ink layer applied to the light-concentrating structure after it has been prepared; this ink layer can be used to form colored patterns or to achieve specific functions of various functional inks.

[0197] It should be noted that the ink layer and the light-gathering structure have different refractive indices, which can absorb stray light passing through the light-gathering structure and increase the refractive index of the light-gathering structure.

[0198] In some embodiments, such as Figure 1 , Figure 5a and Figure 5b As shown, the display panel 10 in this embodiment may further include: an encapsulation layer 18, which is stacked between the touch layer 12 and the light-emitting layer 13, for encapsulating the pixel units in the light-emitting layer 13 to isolate external moisture (such as humidity in the air) and oxygen and to prevent external forces from damaging the pixel units.

[0199] The encapsulation layer may include, but is not limited to, chemical vapor deposition (CVD) structures, inkjet printing (IJP) structures, etc.

[0200] like Figure 1 , Figure 5a and Figure 5b As shown, the above-mentioned display panel 10 may further include: a planarization layer 19, which is stacked between the light-emitting layer 13 and the driving circuit layer 16, for filling the unevenness of the surface of the driving circuit layer 16 and providing a flat surface for the setting of the light-emitting layer 13.

[0201] The planarization layer can be a polymer layer; the material of the planarization layer can be, but is not limited to, polyacrylate or poly(p-xylene).

[0202] In this embodiment of the disclosure, such as Figure 1 , Figure 5a and Figure 5b As shown, the light-concentrating structure 14 can be stacked between the touch layer 12 and the ink layer; or it can be stacked between the planarization layer 19 and the light-emitting layer 13; or it can be stacked between the filter layer 15 and the ink layer.

[0203] It is understandable that, in order to improve the light transmittance of the display panel corresponding to the first area, transparent materials can be used in the encapsulation layer and the planarization layer at positions opposite to the first area, so as to improve the light transmittance of the display panel without affecting the display effect.

[0204] It should be noted that the specific fabrication process of the above-mentioned light-concentrating structure can be selected according to the actual application scenario, and the embodiments disclosed herein are not limited thereto. For example, the light-concentrating structure can be fabricated on the touch layer, filter layer, or planarization layer using photolithography or nanoimprint technology.

[0205] For example, such as Figure 8 As shown, the preparation process of the yellow light process can be as follows: coating microprism material L2 on the touch layer, exposure, development, thermal reflow, coating ink material on the microprism structure formed after thermal reflow to form the above-mentioned display panel.

[0206] like Figure 9 As shown, the preparation process of nanoimprint technology can be as follows: a microprism material L2 is coated on the touch layer 12, the microprism material L2 is nanoimprinted (mask L4), and ultraviolet light L3 is used to solidify the microprism material L2 to form a pattern structure (i.e., light-concentrating structure 14), the mask L4 on the light-concentrating structure 14 is peeled off, and an ink material (i.e., ink layer 17) is coated on the light-concentrating structure 14 to form the above-mentioned display panel.

[0207] This disclosure provides an electronic device that may include at least a display panel as described in the above embodiments of this disclosure.

[0208] In this embodiment of the disclosure, the aforementioned electronic device can be any device with a display panel, such as a mobile phone, laptop computer, in-vehicle device, tablet computer, personal digital assistant (PDA), mobile internet device (MID), wearable device, etc.

[0209] The electronic device proposed in this disclosure can add a light-concentrating structure on the substrate of the display panel of the electronic device along the stacking direction of the light-emitting layer, and the position of the light-concentrating structure is opposite to the gap area between any two pixel units in the multiple pixel units of the light-emitting layer. This can concentrate ambient light passing through the gap area or concentrate ambient light into the gap area, so as not to affect the normal display of the pixel units in the display panel. In this way, while ensuring the display quality of the display panel, the light transmittance of the display panel can be improved, thereby increasing the amount of light entering the electronic device where the display panel is located for taking pictures and improving the picture quality of the electronic device.

[0210] In some embodiments, the above-mentioned electronic device further includes:

[0211] The display panel is mounted on the middle frame;

[0212] The circuit board is located inside the middle frame.

[0213] The camera module is mounted on the circuit board and located between the circuit board and the display panel, and is positioned opposite to a first area of ​​the base of the display panel.

[0214] Here, the aforementioned mid-frame can be a frame in an electronic device used to support, fix, and protect internal components; the display panel of the electronic device can be mounted on the mid-frame, which can be located between the display panel and the back cover of the electronic device.

[0215] The aforementioned circuit board can be a printed circuit board (PCB) in electronic devices, made of double-sided fiberglass board; the circuit board can be used to support various components such as camera modules, and can realize electrical connection or electrical insulation between various components.

[0216] The aforementioned camera module can be a module used to capture images in an electronic device; for example, the camera module can be an under-display camera, i.e., a front-facing camera, in electronic devices such as mobile phones or tablets.

[0217] It should be noted that the camera module is completely hidden below the display panel, that is, the camera module is set between the circuit board and the display panel in the middle frame, without the need to create a notch, cutout, or use a mechanical lifting structure on the display panel; the camera module is set opposite to the first area of ​​the display panel's base, so the ambient light can be gathered to the camera module through the light-gathering structure set in the display panel, thereby increasing the amount of light entering the camera module when taking pictures and improving the image quality of the camera module.

[0218] In some embodiments, the light-concentrating structure of the display panel projects onto the circuit board and is located on the camera module.

[0219] Ambient light is transmitted to the camera module via a light-focusing structure, a gap area of ​​the display panel, and a first area; or, the ambient light is transmitted to the camera module via a gap area, a light-focusing structure, and a first area.

[0220] Here, the projection of the light-concentrating structure of the display panel onto the circuit board can be located on the camera module. That is, the light-concentrating structure can transmit the gathered ambient light to the camera module to increase the amount of light entering the camera module in the electronic device, thereby improving the photo quality of the electronic device.

[0221] It should be noted that, taking the under-display camera module as an example, the substrate of the display panel has a first area for transmitting ambient light to the under-display camera. When the light-concentrating structure is stacked on the side of the touch layer or the filter layer away from the substrate, ambient light outside the display panel can be transmitted to the camera module, i.e., the under-display camera, through the light-concentrating structure, the openings or transparent materials of the touch layer, the gaps in the light-emitting layer, and the first area; when the light-concentrating structure is stacked between the substrate and the light-emitting layer, ambient light outside the display panel can also be transmitted to the camera module, i.e., the under-display camera, through the openings or transparent materials of the touch layer, the gaps in the light-emitting layer, the light-concentrating structure, and the first area.

[0222] In this embodiment, a light-gathering structure can be added to the first region of the substrate of the electronic device's display panel along the stacking direction of the light-emitting layer. The position of the light-gathering structure is opposite to the gap region between any two pixel units in the plurality of pixel units of the light-emitting layer. The camera module is positioned opposite to the first region of the substrate of the display panel. This allows the ambient light passing through the gap region to be gathered or the ambient light to be gathered to the gap region, so as not to affect the normal display of the pixel units in the display panel. This improves the light transmittance of the display panel while ensuring the display quality of the display panel, thereby increasing the amount of light entering the electronic device where the display panel is located and improving the image quality of the electronic device.

[0223] Figure 10 This is a structural block diagram of an electronic device according to an exemplary embodiment. For example, the electronic device 1000 may be a mobile phone, computer, in-vehicle device, digital broadcasting terminal, messaging device, game console, tablet device, medical device, fitness device, personal digital assistant, etc.

[0224] Reference Figure 10 The electronic device 1000 may include one or more of the following components: processing component 1002, memory 1004, power supply component 1006, multimedia component 1008, audio component 1010, input / output (I / O) interface 1012, sensor component 1014, and communication component 1016.

[0225] Processing component 1002 typically controls the overall operation of electronic device 1000, such as operations associated with at least one of display, telephone call, data communication, camera operation, and recording operation. Processing component 1002 may include one or more processors 1020 to execute instructions to perform all or part of the steps of the methods described above. Furthermore, processing component 1002 may include one or more modules to facilitate interaction between processing component 1002 and other components.
