[0003] In the related art, automatic adjustment of the brightness of a display screen is achieved by setting an ambient light sensor in the electronic device. Currently, the ambient light sensor is interfered by the light emitted by the display screen itself during operation, resulting in inaccurate measurement results of the ambient light brightness, which in turn leads to inaccurate adjustment of the brightness of the display screen. Summary of the invention

[0007] The display screen assembly and electronic device provided by the present application place the shielding portion in the pixel circuit below the anode of the pixel, so that most of the light that leaks downward through the anode when the pixel emits light can be blocked by the shielding portion, thereby preventing this part of the light from being captured by the ambient light sensor inside the electronic device, thereby improving the accuracy of the brightness collection of the ambient light and ensuring the accuracy of the brightness adjustment of the display screen.

[0015] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0016] With the advent of the mobile Internet era, the number of smart electronic devices continues to rise. At present, electronic devices are usually equipped with display screens, which light up when working and turn off when not working. In different environments, the brightness of the display screen can be automatically adjusted, which can adapt to the environment, better protect the user's eyes, and save power consumption.

[0017] In the related art, automatic adjustment of the brightness of a display screen is achieved by setting an ambient light sensor in the electronic device. Currently, the ambient light sensor is interfered by the light emitted by the display screen itself during operation, resulting in inaccurate measurement results of the ambient light brightness, which in turn leads to inaccurate adjustment of the brightness of the display screen.

[0018] At present, the ambient light sensor in electronic devices is usually set below the display assembly. When the display is emitting light, there are mainly three light leakage modes: the first is the downward leakage of the anode. The reason is that the transparency of the anode is high. After the display is emitting light, it can penetrate the anode and enter the ambient light sensor downward. The second is the lateral leakage of the pixel layer. The main reason is that after the pixel emits light, it leaks through the side wall of the groove of the organic layer and is reflected downward by the cathode. The third is that the pixel emits light upward and is reflected downward by the touch metal wiring of the capacitive touch layer. Among them, the amount of light reflected by the touch metal wiring is small, and the error caused by the ambient light brightness detection can be basically ignored.

[0019] Based on this, the inventor of the present application proposes a display screen assembly and an electronic device, in order to at least partially improve the above technical problems. The embodiments of the present application will be described in detail below in conjunction with the accompanying drawings.

[0020] See also Figure 1 This embodiment provides an electronic device 10 , including a middle frame 20 , a display screen assembly 30 , and a light sensor 100 , wherein the display screen assembly 30 is assembled on the middle frame 20 .

[0021] Please also read Figure 1 and Figure 2 , wherein the middle frame 20 includes a middle plate 21 and a frame 22, wherein the middle plate 21 is a roughly plate-shaped structure and is used to install various types of components, the frame 22 is surrounded by the middle plate 21 and connected to the middle plate 21, and the display screen assembly 30 is installed on the frame 22 during assembly and is roughly spaced relative to the middle plate 21. In some embodiments, refer to Figure 3 The frame 22 is formed with a step 23 facing inward, and the step 23 includes a step surface and an inner side surface connected to the step surface, and the angle between the step surface and the inner side surface is approximately 90°.

[0022] The light sensor 100 may be, for example, an ambient light sensor 100, an under-screen optical fingerprint sensor, an under-screen camera, and the like. In this embodiment, the ambient light sensor 100 is taken as an example for introduction. It should be noted that in some other embodiments, the light sensor 100 may be one or more, and this embodiment does not limit this. The ambient light sensor 100 is arranged inside the middle frame 20 and below the display screen assembly 40. The ambient light sensor 100 is used to detect the intensity of the ambient light, and then can be used to adjust the display brightness of the display screen assembly 40. Specifically, the electronic device 10 may also include a control unit (not shown in the figure), the control unit is electrically connected to the ambient light sensor 100, and the control unit is electrically connected to the display screen assembly 40. The control unit is used to control the display screen assembly 40 to adjust the display brightness according to the ambient light brightness detected by the ambient light sensor 100, for example: when the ambient light brightness is weak or weakens, the display brightness of the display screen assembly 40 is reduced, and when the ambient light brightness is strong or strong, the display brightness of the display screen assembly 40 is increased.

[0023] The control unit may include a memory and a processor, and the processor may include one or more processing cores. The processor uses various interfaces and lines to connect various parts of the entire electronic device 10, and executes various functions and processes data of the electronic device 10 by running or executing instructions, programs, code sets or instruction sets stored in the memory, and calling data stored in the memory. Optionally, the processor can be implemented in at least one hardware form of digital signal processing (Digital Signal Processing, DSP), field programmable gate array (Field-Programmable Gate Array, FPGA), and programmable logic array (Programmable Logic Array, PLA). The processor can integrate one or a combination of a central processing unit (Central Processing Unit, CPU), a graphics processing unit (Graphics Processing Unit, GPU) and a modem. Among them, the CPU mainly processes the operating system, user interface and application programs; the GPU is responsible for rendering and drawing display content; and the modem is used to process wireless communications. It can be understood that the above-mentioned modem may not be integrated into the processor, but implemented separately through a communication chip.

[0024] The memory may include a random access memory (RAM) or a read-only memory (ROM). The memory may be used to store instructions, programs, codes, code sets or instruction sets. The memory may include a program storage area and a data storage area, wherein the program storage area may store instructions for implementing an operating system, instructions for implementing at least one function (such as a touch function, a sound playback function, an image playback function, etc.), instructions for implementing the following various method embodiments, etc. The data storage area may also store data (such as a phone book, audio and video data, chat record data) created by the electronic device 10 during use.

[0025] See also Figure 4 As a more specific embodiment, the display screen assembly 40 includes a light-transmitting cover plate 43, a capacitive touch layer 42 and a light-emitting layer 41. The light-transmitting cover plate 43 is a roughly flat plate structure, for example, it can be made of tempered glass, which can protect the light-emitting layer 41 and can transmit light. The capacitive touch layer 42 can be used to detect the user's control operation on the touch surface and convert it into a corresponding operation signal. The capacitive touch layer 42 can be made of, for example, indium tin oxide (ITO) so that the capacitive touch layer 42 can be light-transmitting.

[0026] The light emitting layer 41 may be an LED, an OLED, etc., which is not limited in this embodiment. Figure 5 , the light-emitting layer 41 includes an organic layer 411, and the organic layer 411 includes a plurality of pixels 4111, and the light-emitting layer 41 also includes a pixel electrode 412, and the pixel electrode 412 includes an anode 4121 and a cathode 4122. Specifically, the anode 4121 and the cathode 4122 are used to form an electric field, thereby driving the pixel to emit light. Each pixel may include a red light (R) sub-pixel, a blue light (B) sub-pixel, and a green light (G) sub-pixel, and the plurality of pixels may be arranged in a predetermined manner. For example, in one embodiment, the plurality of pixels may be neatly arranged in an RGB arrangement. In another embodiment, each pixel may include a red light (R) sub-pixel, a blue light (B) sub-pixel, a green light (G) sub-pixel, and a white light (W) sub-pixel, and the plurality of pixels may be neatly arranged in an RGBW arrangement. In another embodiment, the plurality of pixels may be arranged in a Pentile arrangement (P arrangement), and each pixel is composed of an RG or BG sub-pixel, and the green pixel is complete. The present application does not limit the arrangement of multiple pixels, for example, it can also be a diamond arrangement, a Delta arrangement, etc.

[0027] An organic layer groove 413 is formed between adjacent pixels, and most of the anode 4121 is disposed in the area corresponding to the organic layer groove 413 and is located on the side of the light-emitting layer 41 away from the cathode 4122. In some embodiments, at least a portion of the anode 4121 extends below the pixel, so that the electric field formed by the anode 4121 and the cathode 4122 can drive the pixel to emit light. The cathode 4122 is disposed above the organic layer 411, that is, the cathode 4122 is disposed on the side of the pixel away from the anode 4121. The cathode 4122 is electrically connected to the pixel circuit 44 and can be made of materials such as Mg / Ag. The cathode 4122 is configured to be attached to the light-emitting layer 41 and is recessed at a position corresponding to the organic layer groove 413. Because of the presence of the organic layer groove 413, when the pixel emits light, it will leak light laterally toward the direction of the organic layer groove 413. This part of the laterally emitted light will be reflected by the cathode 4122 toward the bottom of the display screen to form lateral light leakage.

[0028] In a more specific embodiment, the anode 4121 can be made of ITO / Ag / ITO material. Specifically, the anode 4121 includes a first conductor layer, a metal layer and a second conductor layer stacked in sequence. The first conductor layer is electrically connected to the pixel circuit 44. The first conductor layer and the second conductor layer can both be made of indium tin oxide transparent conductive material. The metal layer is located between the first conductive layer and the second conductive layer. This structure combines the excellent properties of indium tin oxide and metal, maintaining the light transmittance and conductivity of indium tin oxide, and utilizing the high reflectivity and conductivity of metal. As a more specific embodiment, the metal layer can be a silver (Ag) layer. Ag is a metal material with high reflectivity in the visible light range and excellent photoelectric properties. It can be used as a reflective material with high application value in the visible light band. At the same time, the resistivity of Ag is usually 10-6Ω·cm, and its conductivity is outstanding, so it can be used as an electrode material.

[0029] As mentioned above, the light emitted by the light emitting layer 41 can propagate to the bottom of the display screen when passing through the anode 4121, thereby causing errors in the detection results of the ambient light sensor 100 below. Therefore, by reducing the light transmittance of the anode 4121, this part of the light can be reduced from entering the ambient light sensor 100. In some embodiments, the thickness of the metal layer is greater than the thickness of the first conductor layer and the thickness of the second conductor layer. Since the light transmittance of the metal layer is poor, by increasing the thickness of the metal layer, the light transmittance of the anode 4121 can be further reduced, so that it is not easy for light to pass through the anode 4121 and enter the ambient light sensor 100 below, thereby reducing interference with the detection results of the ambient light sensor 100.

[0030] For every 10nm increase in the thickness of the metal layer, the transmittance of the anode 4121 is reduced to 1 / 4 of the original value, while having no effect on the forward light emission of the light-emitting layer 41. As a more specific embodiment, the metal layer is an Ag layer, and the thickness of the metal layer can be 80nm-120nm, and in particular, for example, can be 80nm-100nm, 100nm-120nm, etc. At this thickness, the transmittance of the anode 4121 is low, and the amount of light leakage downward is significantly reduced, while having no effect on the forward light emission of the display assembly 40.

[0031] In this embodiment, the pixel circuit 44 includes a shielding portion, which is disposed below the anode 4121 and corresponds to the anode 4121, and the projection of the anode 4121 on the pixel circuit 44 is located within the range of the shielding portion. The shielding portion can shield the leakage light passing through the anode 4121, preventing this part of the light from entering the ambient light sensor 100 below, thereby improving the measurement and detection accuracy of the ambient light sensor 100.

[0032] In some embodiments, the shielding portion may also protrude a portion relative to the edge of the anode 4121, that is, there is a gap between the edge of the projection of the anode 4121 on the pixel circuit 44 and the edge of the shielding portion. The advantage of this arrangement is that after the pixel emits light, the lateral leakage light leaks out through the side wall of the organic layer groove and is reflected downward by the cathode. When propagating downward, it will also be blocked by the shielding portion, thereby preventing this part of the light from entering the ambient light sensor 100 below, thereby improving the measurement and detection accuracy of the ambient light sensor 100.

[0033] The probability of light leakage from the anode 4121 of the green pixel is greater than that from the red pixel and the blue pixel. Therefore, in some embodiments, the shielding portion may be preferably disposed below the anode 4121 corresponding to the green pixel, so as to improve the reflectivity of the light leakage. Of course, it is understandable that a shielding portion may also be disposed below the anode 4121 of the red pixel and the anode 4121 of the blue pixel, and this is not limited in this embodiment.

[0034] The pixel circuit 44 is located below the light emitting layer 41. The pixel circuit 44 is electrically connected to the cathode 4122 and the anode 4121 of the pixel electrode 412. The pixel circuit 44 includes a shielding metal layer 441, a gate layer 442, and a source-drain layer 443. The gate layer 442 is disposed on the surface of the shielding metal layer 441. The source-drain layer 443 is disposed on the surface of the gate layer 442 away from the shielding metal layer 441. The pixel circuit 44 also includes a metal routing, which is disposed on the gate layer 442 and the source-drain layer 443 and connects the gate, source, and drain corresponding to each pixel, thereby realizing the connection routing of the pixel electrode 412. The metal routing is configured in a roughly grid shape and corresponds to a plurality of pixels. The metal routing is electrically connected to the cathode 4122 and the anode 4121 of the pixel electrode 412 corresponding to each pixel.

[0035] In the display screen assembly 40, the electrical signal may be subject to various interferences during the transmission process, resulting in the image effect not being as expected. A shielding electrode 4431 is provided in the source-drain layer 443, and the shielding electrode 4431 can cover or be close to these interference sources, thereby blocking or weakening the interference signal, ensuring that the signal received by the pixel electrode 412 is purer and more stable. The shielding electrode 4431 can also inhibit the charge generated in the photoelectric conversion film of a certain pixel and entering the semiconductor layer from flowing out to adjacent pixels. This inhibitory effect can further improve the quantum efficiency of the pixel, reduce the crosstalk of the charge between different pixels, and thus improve the clarity and contrast of the image. The shielding electrode 4431 is a point to prevent the data voltage jump from affecting the key nodes of the pixel driving circuit, which can improve the display effect. The shielding electrode 4431 is usually made of a large-area metal material in a rectangular shape.

[0036] In a more specific embodiment, the shielding portion may include a shielding electrode 4431, which is arranged below the anode 4121, and the projection of the anode 4121 on the pixel circuit 44 is located within the range of the shielding electrode 4431. The shielding electrode 4431 is made of a metal material, which itself is opaque, and the metal wires constituting the shielding electrode 4431 are roughly rectangular structures. Therefore, it is arranged below the anode 4121 and corresponds to the anode 4121, which can block the leakage light passing through the anode 4121, thereby preventing this part of the light from entering the ambient light sensor 100 below, thereby improving the measurement and detection accuracy of the ambient light sensor 100.

[0037] Among them, the projection of the anode 4121 on the pixel circuit 44 can be completely located within the range of the shielding electrode 4431, so as to completely block the light transmitted from the anode 4121 as much as possible. In particular, the projection of the anode 4121 on the pixel circuit 44 can also be located in the central area of ​​the shielding electrode 4431, that is, the projection area of ​​the anode 4121 on the pixel circuit 44 is smaller than the area of ​​the shielding electrode 4431. This arrangement can prevent the light leaking from the anode 4121 from scattering during the propagation process. When it propagates to the shielding electrode 4431, it can still bypass the shielding electrode 4431 and continue to propagate downward. At the same time, the lateral leakage light that leaks out through the side wall of the organic layer groove after the pixel emits light and is reflected downward by the cathode will also be blocked by the shielding electrode 4431 when propagating downward, so as to prevent this part of the light from entering the ambient light sensor 100 below, thereby improving the measurement and detection accuracy of the ambient light sensor 100.

[0038] In another embodiment, the gate layer 442 includes a first electrode plate 4421 and a second electrode plate 4422, which are arranged at a relative interval to form a storage capacitor. The storage capacitor is used to maintain the pixel voltage stable, and can maintain the voltage stability on the liquid crystal pixel for a long time after the TFT is turned off, ensuring the continuity of the image display. At the same time, the storage capacitor can also reduce image flickering and support the light-emitting layer 41 to continuously emit light.

[0039] In another embodiment, the shielding portion includes the first electrode plate 4421 and the second electrode plate 4422, and the projection of the anode 4121 on the pixel circuit 44 is located within the range of the first electrode plate 4421 and / or the second electrode plate 4422. The first electrode plate 4421 and / or the second electrode plate 4422 are made of metal material, which itself is not light-transmitting. The metal wires constituting the first electrode plate 4421 and / or the second electrode plate 4422 are roughly rectangular structures. Therefore, they are arranged below the anode 4121 and corresponding to the anode 4121, which can block the leakage light passing through the anode 4121, prevent this part of the light from entering the ambient light sensor 100 below, and improve the measurement and detection accuracy of the ambient light sensor 100.

[0040] The projection of the anode 4121 on the pixel circuit 44 can be completely located within the range of the first electrode plate 4421 and / or the second electrode plate 4422, so as to completely block the light transmitted from the anode 4121 as much as possible. In particular, the projection of the anode 4121 on the pixel circuit 44 can also be located in the central area of ​​the first electrode plate 4421 and / or the second electrode plate 4422, that is, the projection area of ​​the anode 4121 on the pixel circuit 44 is smaller than the area of ​​the first electrode plate 4421 and / or the second electrode plate 4422. This arrangement can prevent the light leaking from the anode 4121 from scattering during the propagation process, and when propagating to the first electrode plate 4421 and / or the second electrode plate 4422, it can still bypass the first electrode plate 4421 and / or the second electrode plate 4422 and continue to propagate downward. At the same time, the lateral leakage light that leaks out through the side wall of the organic layer groove after the pixel emits light and is reflected downward by the cathode will also be blocked by the first electrode 4421 and / or the second electrode 4422 when propagating downward, thereby preventing this part of the light from entering the ambient light sensor 100 below, thereby improving the measurement and detection accuracy of the ambient light sensor 100.

[0041] The shielding metal layer 441 can shield external electromagnetic interference and avoid electrostatic influence. In this embodiment, the shielding metal layer 441 is located below the gate layer 442. In another embodiment, the shielding portion may include a shielding metal layer 441, which is disposed below the anode 4121, and the projection of the anode 4121 on the pixel circuit 44 is located within the range of the shielding metal layer 441. The shielding metal layer 441 is made of a metal material, which itself is opaque. The metal wires constituting the shielding metal layer 441 are roughly rectangular structures. Therefore, it is arranged below the anode 4121 and corresponds to the anode 4121, which can block the leakage light passing through the anode 4121, and prevent this part of the light from entering the ambient light sensor 100 below, thereby improving the measurement and detection accuracy of the ambient light sensor 100.

[0042] Among them, the projection of the anode 4121 on the pixel circuit 44 can be completely located within the range of the shielding metal layer 441, so as to completely block the light transmitted from the anode 4121 as much as possible. In particular, the projection of the anode 4121 on the pixel circuit 44 can also be located in the central area of ​​the shielding metal layer 441, that is, the projection area of ​​the anode 4121 on the pixel circuit 44 is smaller than the area of ​​the shielding metal layer 441. This setting method can avoid the phenomenon of scattering and the like of the light leaking through the anode 4121 during the propagation process. When propagating to the shielding metal layer 441, it can still bypass the shielding metal layer 441 and continue to propagate downward. At the same time, the lateral leakage light that leaks out through the side wall of the organic layer groove after the pixel emits light and is reflected downward by the cathode will also be blocked by the shielding metal layer 441 when propagating downward, so as to prevent this part of the light from entering the ambient light sensor 100 below, thereby improving the measurement and detection accuracy of the ambient light sensor 100.

[0043] It is understandable that in some other embodiments, the shielding portion may include the shielding electrode 4431, the first electrode plate 4421, the second electrode plate 4422 and the shielding metal layer 441 at the same time, or only include one or more of them, which is not limited in this embodiment.

[0044] In the display screen assembly 40 in the above embodiment, the shielding electrode 4431, the shielding metal layer 441, or the first electrode plate 4421 and the second electrode plate 4422 in the pixel circuit 44 are arranged below the anode 4121 as a shielding portion, and no additional components are required. The shielding portion shields and reflects the leaked light passing through the anode 4121, so that this part of the light cannot enter the ambient light sensor 100, thereby ensuring the detection accuracy of the ambient light sensor 100.
