[0024] The following will be combined with Figures 2 to 4 Describe a screen assembly and an electronic device according to an embodiment of the present application.
[0025] In some embodiments of the present application, a screen assembly is provided. Figure 2 The structural schematic diagram of the screen assembly according to the embodiment of the present application is shown. Figure 3 Shown is Figure 2 The partial enlarged view at A in Figure 2 And Figure 3 As shown in
[0026] In an embodiment of the present application, the screen assembly 100 includes a light-emitting layer assembly 102 and a support layer 104. Among them, the light-emitting layer assembly 102 is used to emit light during the operation of the screen assembly 100 to achieve the display function of the screen assembly 100. Specifically, the light-emitting layer may include Active Matrix Organic Light Emitting Diode (AMOLED). The support layer 104 can be used to support the light-emitting layer to ensure the stability of the light-emitting layer assembly 102. Especially when the screen assembly 100 is a foldable screen or a curved screen, the support layer 104 can effectively support the light-emitting layer assembly 102 during the bending process of the screen, ensuring the structural stability of the light-emitting layer assembly 102.
[0027] Further, the screen assembly 100 further includes a circuit board assembly 108, and the circuit board assembly 108 is connected to the light-emitting layer assembly 102. Through the circuit board assembly 108, the control of the light-emitting layer assembly 102 can be realized, that is, the different brightness and combination modes of multiple Active Matrix Organic Light Emitting Diodes in the light-emitting layer assembly 102 are controlled, and then different contents are displayed on the screen assembly 100.
[0028] Further, the screen assembly 100 further includes a conductive assembly 106. The conductive assembly 106 is used for grounding. Moreover, both the light-emitting layer assembly 102 and the circuit board assembly 108 are connected to the conductive assembly 106, so that the light-emitting layer assembly 102 and the circuit board assembly 108 can be grounded through the conductive assembly 106, thereby ensuring the grounding requirements of the light-emitting layer assembly 102 and the circuit board assembly 108 to ensure the normal operation of the light-emitting layer assembly 102 and the circuit board assembly 108.
[0029] Moreover, at least a part of the conductive assembly 106 is disposed within the support layer 104, that is, at least a part of the conductive assembly 106 can be disposed by utilizing the internal space of the support layer 104, so that there is no need to provide an additional conductive layer to achieve grounding. That is, by disposing at least a part of the conductive assembly 106 within the support layer 104, there is no need to provide copper foil and conductive adhesive as in the related art to meet the grounding requirements of the light-emitting layer assembly and the circuit board. Therefore, compared with the screen assembly in the related art, the screen assembly 100 of the present application can effectively reduce the thickness of the screen assembly 100 on the basis of grounding the light-emitting layer assembly 102 and the circuit board assembly 108 through the conductive assembly 106, which is beneficial to the thin and light design of the screen assembly 100.
[0030] In addition, compared with the related art where grounding is achieved through copper foil and conductive adhesive, the screen assembly 100 of the present application does not require the setting of copper foil, thereby avoiding unnecessary electrical signals that may be generated when current passes through the copper foil during the operation of the screen assembly 100. That is, it avoids the interference caused by the unnecessary electrical signals generated by the copper foil to the operation of the screen assembly 100, and improves the stability of the operation of the screen assembly 100. At the same time, without the need to set copper foil and conductive adhesive, it also avoids the situation where the conductive adhesive peels off during the operation of the screen assembly 100 in a high-temperature and high-humidity environment, resulting in the inability of the copper foil to be stably grounded.
[0031] The screen assembly 100 of the embodiment of the present application includes a light-emitting layer assembly 102, a support layer 104, a conductive assembly 106, and a circuit board assembly 108. Among them, both the light-emitting layer assembly 102 and the circuit board assembly 108 are grounded through the conductive assembly 106, and at least a part of the conductive assembly 106 is disposed within the support layer 104, so that at least a part of the conductive assembly 106 can be disposed by utilizing the internal space of the support layer 104. By disposing at least a part of the conductive assembly 106 within the support layer 104, there is no need to set copper foil and conductive adhesive as in the related art to meet the grounding requirements of the light-emitting layer assembly and the circuit board. Compared with the screen assembly in the related art, the screen assembly 100 of the present application can effectively reduce the thickness of the screen assembly 100 on the basis of grounding the light-emitting layer assembly 102 and the circuit board assembly 108 through the conductive assembly 106, which is beneficial to the thin and light design of the screen assembly 100.

[0033] In the embodiment of the present application, as Figure 3 shown, the support layer 104 may include a carrier 110 and a plurality of support fibers 112 disposed within the carrier 110. By setting the plurality of support fibers 112, the structural strength of the support layer 104 during deformation can be improved, so that the support layer 104 can withstand greater deformation. By setting the carrier 110, the connection of the plurality of support fibers 112 is realized, thereby further improving the structural integrity of the support layer 104 and further improving the structural strength of the support layer 104. Specifically, the support fibers 112 may be carbon fibers to ensure the strength of the support fibers 112, and the carrier 110 may be a resin, specifically an epoxy resin material, that is, the carbon fibers are wrapped inside the resin material.
[0034] Further, the conductive component 106 may include a metal coating 114 and a plurality of first conductive particles 116.

At the same time, the plurality of first conductive particles 116 are disposed inside the carrier 110 so that adjacent metal coatings 114 can be connected through the plurality of first conductive particles 116.
[0035] It can be understood that the support fibers 112 are usually arranged in an orderly manner within the carrier 110, and a metal coating 114 is disposed on the surface of each support fiber 112. At the same time, by disposing a plurality of first conductive particles 116 between two adjacent support fibers 112, two adjacent support fibers 112 are connected in series through the plurality of first conductive particles 116. That is, the plurality of support fibers 112 within the carrier 110 can be connected in series through the plurality of first conductive particles 116, thereby reducing the impedance of the support layer 104. At the same time, grounding the metal coating 114 also realizes the grounding of the conductive component 106.
[0036] Further, both the light-emitting layer assembly 102 and the circuit board assembly 108 are connected to the plurality of first conductive particles 116, thereby realizing the grounding of the light-emitting layer assembly 102 and the circuit board assembly 108 through the conductive component 106, meeting the grounding requirements of the light-emitting layer assembly 102 and the circuit board assembly 108.

Thus, there is no need to provide copper foil and conductive adhesive as in the related art to meet the grounding requirements of the light-emitting layer assembly and the circuit board assembly. On the basis of realizing the grounding of the light-emitting layer assembly 102 and the circuit board assembly 108 through the conductive component 106, the thickness of the screen assembly 100 can be effectively reduced, which is beneficial to the thin and light design of the screen assembly 100.

[0042] Furthermore, through the connecting portion 122, an electrical connection between the flexible circuit board 120 and the conductive component 106 can be achieved, that is, the flexible circuit board 120 is grounded through the conductive component 106. Specifically, at least a part of the connecting portion 122 can be disposed within the carrier 110 of the support layer 104, so that the connecting portion 122 can be connected to the plurality of first conductive particles 116 within the carrier 110, and further the flexible circuit board 120 is grounded through the first conductive particles 116 and the metal coating 114.
