[0059] Here, exemplary embodiments will be described in detail, and their examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0060] The solution provided by the present disclosure can be used in the application scenario of the display screen design of intelligent devices. For the sake of easy understanding, some terms and application scenarios related to the embodiments of the present disclosure will be briefly introduced below.

[0061] Pixel: Also known as an image element, it is the smallest unit representing an image. Specifically, an image can be regarded as composed of several small squares, where each small square has a definite position and an assigned color value, and these small squares can be regarded as the pixels of the image. When a computer device's screen (such as a display screen) displays an image, it can display one pixel in the image through one or more pixel display components.

[0062] 7T1C circuit: It refers to a driving circuit that includes 7 thin film transistors (TFTs) and 1 storage capacitor (C), simply referred to as a 7T1C circuit.

[0063] Evaporation coating: A method of heating a coating material in a vacuum environment to vaporize the coating material and deposit it on the surface of the material to be coated to obtain a thin film material.

[0064] Please refer to Figure 1 , which shows a cross-sectional schematic view of the stacked arrangement of pixel display components of an OLED provided by an embodiment of the present disclosure. As Figure 1As shown in the figure, the screen display component of the OLED display screen includes a cathode 101, a pixel display component 102, and a substrate 103; the pixel display components 102 are also separated by PDL. In the pixel display component 102, there are a light-emitting unit 104, an anode 105, and a driving circuit 106. Among them, the cathode 101 uses a magnesium-silver (Mg / Ag) material, the light-emitting unit 104 can be a red OLED material, a green OLED material, or a blue OLED material, the anode 105 uses a hybrid material of ITO and silver (Ag) or a stacked material (for example, an Ag material is provided on the surface of the ITO material, etc.), the driving circuit can be a 7T1C circuit, a 6T1C circuit, a 5T2C circuit, etc., and the substrate 103 can use a glass substrate, a polyimide (PI) substrate, etc. Optionally, the pixel display component can include multiple ones.

[0065] Optionally, the driving circuit can be fabricated using low-temperature polysilicon technology (LTPS) or indium gallium zinc oxide (IGZO) display screen technology. Optionally, the driving circuit can also include scan lines and data lines.

[0066] As Figure 1 shown in the stacked arrangement structure of the pixel display components of the OLED, since the material used for the anode is a non-translucent material and the driving circuit is also non-translucent, therefore, when devices such as a camera and a sensor are arranged below this area, the camera, the sensor, etc. cannot collect light signals above the pixel display components of the OLED, making it limited to fully apply this arrangement structure of the OLED to the display screen and realize a full-screen display.

[0067] In the related art, in order to avoid light blocking of devices such as a camera and a sensor arranged below the display screen, the stacked arrangement of the pixel display components of the above OLED can be adjusted. Please refer to Figure 2 , which shows a cross-sectional schematic diagram of the stacked arrangement of the pixel display components of an OLED related to an embodiment of the present disclosure. As Figure 2 shown, the screen display component of the OLED display screen is formed by combining a cathode 201, several pixel display components 202, a substrate 203, and a driving circuit 204. The pixel display components 202 are also separated by PDL. In the pixel display component 202, there are a light-emitting unit 205 and an anode 206. Among them, the above Figure 1 shown driving circuit is moved to Figure 2The positions shown (positions outside the pixel display component, on both sides of the pixel display component). Additionally, in this solution, the anode 206 is entirely made of ITO material, thereby improving the light transmittance of the anode. The cathode 201 uses a material with better light transmittance than the Mg / Ag material, also improving the light transmittance of the cathode. Optionally, the materials of the substrate 203, the driving circuit 204, and the light-emitting unit 205 can be similar to those Figure 1 shown, which will not be elaborated here.

[0068] Please refer to Figure 3 , which shows a schematic diagram of a display screen related to an embodiment of the present disclosure. As Figure 3 shown, in the display screen 300, it includes a first screen area 301, a second screen area 302, a remaining screen area 303, an under-screen camera 304, and an under-screen fingerprint sensor 305. Optionally, in the first screen area 301 and the second screen area 302, they can be arranged in the stacked arrangement manner of the OLED pixel display components as Figure 2 shown. In the remaining screen area 303, they can be arranged in the stacked arrangement manner of the OLED pixel display components as Figure 1 shown, or they can also be arranged in the stacked arrangement manner of the OLED pixel display components as Figure 2 shown. As Figure 3 shown, below the first screen area 301, an under-screen camera 304 is provided. Optionally, since the materials used for each pixel display component in the first screen area 301 are light-transmissive, therefore, this under-screen camera 304 can collect information outside the screen through the first screen area 301 for recognition, achieving the collection work of the camera under the screen; below the second screen area 302, an under-screen fingerprint sensor 305 is provided. Similarly, since the material used for the second screen area 302 is light-transmissive, therefore, this under-screen fingerprint sensor 305 can collect fingerprint information outside the screen through the second screen area 302 for recognition, achieving the collection work of the fingerprint sensor under the screen, thereby enabling the display screen to achieve a full-screen. In addition to the camera and the fingerprint sensor, other sensors that need to collect light, such as a light sensor, a distance sensor, etc., can also be provided below the light-transmissive area of the above display screen 300.

[0069] However, the stronger the light transmittance of a certain area in the display screen, the worse the corresponding screen display effect in that area. Therefore, the display effect of the display screen arranged in the arrangement manner as Figure 2 shown is poor. In addition, when the above Figure 3 shown display screen is displaying, if the pixel display components in the first screen area and the second screen area are arranged in the arrangement manner as Figure 2 shown, while the pixel display components in other parts of the display screen are arranged inFigure 1 If arranged in the arrangement shown, there is a significant difference in the light transmittance between the first screen area and the second screen area of the display screen and the light transmittance of other parts of the display screen. Correspondingly, when displaying content on the display screen, the picture effects shown in the first screen area and the second screen area may be quite different from the picture effects shown in other screen areas, thereby reducing the overall display effect of the display screen.

[0070] To solve the above problems, an embodiment of the present disclosure provides a pixel display component, which can be arranged in a display screen. Please refer to Figure 4 , which shows a side schematic view of the structure of a pixel display component provided by an embodiment of the present disclosure. As Figure 4 shown, the pixel display component 400 includes a light-emitting unit 401 and an anode 402;

[0071] Among them, the anode 402 includes a first anode portion 402a and a second anode portion 402b arranged along the direction parallel to the display screen; the material of the first anode portion 402a is a light-transmitting material, and the material of the second anode portion 402b includes a non-light-transmitting material.

[0072] Optionally, the direction parallel to the display screen can be the horizontal indication direction as Figure 4 shown. The first anode portion 402a and the second anode portion 402b can be arranged in the horizontal direction as Figure 4 shown. Optionally, the number of the first anode portion 402a and the second anode portion 402b can be arbitrary, or the ratio between the area of the first anode portion 402a and the area of the second anode portion 402b can be set by developers according to actual needs.

[0073] Optionally, the material of the above first anode portion can be a light-transmitting material, and the material of the second anode portion can be a non-light-transmitting material. Optionally, the light-transmitting material and the non-light-transmitting material described in the embodiment of the present disclosure can be defined by the light transmittance of the material. For example, if the light transmittance of the first material is not less than the light transmittance of the ITO material, then the first material can be referred to as a light-transmitting material in the embodiment of the present disclosure; if the light transmittance of the second material is less than the light transmittance of the ITO material, then the first material can be referred to as a non-light-transmitting material in the embodiment of the present disclosure.

[0074] Figure 4 also includes the cathode 403 of the display screen and the substrate 404. As Figure 4 shown, the light-emitting unit 401 can be arranged between the cathode 403 and the anode 402 of the display screen, and the anode 402 is arranged between the substrate 404 of the display screen and the light-emitting unit 401. The anode can be arranged on the substrate 404 of the display screen along the Figure 4 shown horizontal direction.

By providing the first anode portion and the second anode portion in the pixel display component, the second anode has a weak light divergence effect on the light emitted by the light-emitting unit, thereby improving the display effect at the position of the pixel display component in the display screen while ensuring the light transmittance at the position of the pixel display component.

[0076] In a possible implementation manner, the above-designed light-emitting unit can correspond to different anode portions, and the corresponding light-emitting unit portions can be designed respectively.

[0077] Among them, the anode 502 includes a first anode portion 502a and a second anode portion 502b arranged in a direction parallel to the display screen; the material of the first anode portion 502a is a light-transmitting material, and the material of the second anode portion 502b includes a non-light-transmitting material.

[0078] Optionally, the direction parallel to the display screen can be the horizontal indication direction as Figure 5 shown, and the first anode portion 502a and the second anode portion 502b can be arranged in the horizontal direction as Figure 5 shown. Optionally, the anode 502 can include at least two first anode portions 502a, and / or, the anode can include at least two second anode portions 502b. That is, the number of the first anode portion 502a and the second anode portion 502b can be arbitrary, or the ratio between the area of the first anode portion 502a and the area of the second anode portion 502b can be set by developers according to actual needs. That is, in the pixel display component 500 as Figure 5 shown, the anode 502 therein can be divided into at least two first anode portions and at least two second anode portions.

[0079] Optionally, the first anode portion 502a of the above anode design can surround the second anode portion 502b; or, the second anode portion 502b can surround the first anode portion 502a. Please refer to Figure 6 , which shows an embodiment of the present disclosure related to Figure 5Top view of a pixel display component. As Figure 6 shown, the pixel display component includes a first anode portion 502a and a second anode portion 502b. Optionally, the second anode portion 502b can be disposed at the pixel center, and a corresponding side view can be as Figure 5 shown. The first anode portion surrounds the periphery of the second anode portion, that is, the first anode portion 502a completely surrounds the second anode portion 502b. Optionally, Figure 6 the position, size, etc. of the second anode portion 502b shown can also be set by developers according to actual needs. Optionally, please refer to Figure 7 , which shows a top view of another pixel display component according to an embodiment of the present disclosure. That is, the first anode portion 502a can be disposed at the pixel center, and the second anode portion 502b surrounds the periphery of the first anode portion 502a, that is, the second anode portion 502b completely surrounds the first anode portion 502a.

[0080] In another possible implementation, the anode in the above pixel display component can include at least two first anode portions 801a, and / or the anode in the above pixel display component can include at least two second anode portions. For example, please refer to Figure 8 , which shows a side view of the structure of a pixel display component according to an embodiment of the present disclosure. As Figure 8 shown, the anode 801 included in the pixel display component 800 is divided into two first anode portions 801a and two second anode portions 801b.

The light-emitting unit is disposed between the cathode 803 of the display screen and the anode 801, and the anode 801 is disposed between the substrate 804 of the display screen and the light-emitting unit. Please refer to Figure 9 , which shows an embodiment of the present disclosure Figure 8 of a top view of a pixel display component. As Figure 9 shown, which shows Figure 8 the positions of the two first anode portions 801a and the two second anode portions 801b set therein. When developers set the anode, they can set the anode as two first anode portions and two second anode portions in the form shown in Figure 9 . Optionally, the pixel display component can also be square or rectangular, that is, the shape of the anode shown in the above Figure 9 can be square or rectangular. Developers can design the anode accordingly to form multiple first anode portions and multiple second anode portions. The embodiments of the present disclosure do not limit this.

[0081] Optionally, the positions of the horizontally arranged first anode portion 502a and second anode portion 502b can be changed to form a situation where the first anode portion 502a does not completely surround the second anode portion 502b. Please refer to Figure 10 , which shows an embodiment of the present disclosure related to Figure 5 a top view of a pixel display component, as Figure 10 shown, in the pixel display component, the anode 502 included therein, which includes a horizontally arranged second anode portion 502b and a first anode portion 502a, is different from the setting position of the second anode portion 502b shown in Figure 5 . Optionally, as Figure 10 shown, the second anode portion 502b can also be set at other positions in the figure (as shown by the dotted line in Figure 10 ), and examples are not given one by one here. Optionally, the first anode portion and the second anode portion included in the anode shown in Figure 8 can also change their setting positions to form a situation where the second anode portion 502b does not completely surround the first anode portion 502a. The embodiments of the present disclosure do not limit this.

[0082] Optionally, the material of the first anode portion can be a light-transmitting material, and the material of the second anode portion can be a non-light-transmitting material. Optionally, the light-transmitting material and the non-light-transmitting material described in the embodiments of the present disclosure can be defined by the light transmittance of the material. For example, if the light transmittance of the first material is not less than the light transmittance of the ITO material, then the first material can be referred to as a light-transmitting material in the embodiments of the present disclosure; if the light transmittance of the second material is less than the light transmittance of the ITO material, then the first material can be referred to as a non-light-transmitting material in the embodiments of the present disclosure.

[0083] Figure 5 also includes the cathode 503 of the display screen and the substrate 504. As Figure 5 shown, the light-emitting unit 501 can be set between the cathode 503 and the anode 502 of the display screen, and the anode 502 is set between the substrate 504 of the display screen and the light-emitting unit 501.

[0084] Optionally, the light-emitting unit 501 further includes a first light-emitting unit portion 501a and a second light-emitting unit portion 501b;

Optionally, the above Figure 8The first anode portion and the second anode portion shown may also respectively correspond to their own first light-emitting unit portion and second light-emitting unit portion, which will not be elaborated here.

[0087] In a possible implementation manner, the first light-emitting unit portion 501a and the second light-emitting unit portion 501b are isolated by a pixel defining layer PDL. As Figure 5 shown, a PDL can be provided between the anode and the cathode. When the light-emitting material of the light-emitting unit portion is vapor-deposited on the PDL on the anode, it can be separated by the PDL from each other, so as to be in different positions, corresponding to different anode portions to form the light-emitting unit portion. That is, the PDL can also control the vapor-deposition range of the light-emitting material of the light-emitting unit.

[0088] In a possible implementation manner, the first light-emitting unit portion 501a can be connected to the second light-emitting unit portion 501b. Please refer to Figure 11 which shows a side schematic view of the structure of a pixel display component related to an embodiment of the present disclosure. As Figure 5 shown, the first light-emitting unit portion 501a and the second light-emitting unit portion 501b can be connected above the PDL. Figure 11

The constituent material of the second anode portion 502b can use a hybrid material or a stacked material of ITO material and silver material. That is to say, the constituent material of the second anode portion can be the same as the material used for the anode shown in Figure 1 shown.

[0091] Optionally, the constituent material of the above cathode can be a silver-magnesium hybrid material; or, the constituent material of the cathode uses a material with a transmittance higher than that of the silver-magnesium hybrid material.
