[0029] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0030] The terminology used in this disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. The singular forms “a,” “the,” and “the” as used in this disclosure and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any and all possible combinations of one or more of the associated listed items.

[0031] It should be understood that, depending on the context, the word “if” as used here can be interpreted as “when”, “when”, or “in response to determination”.

[0032] Some flexible screen devices (such as mobile phones and tablets) are prone to accumulating static electricity during use. If this accumulated static electricity (especially that accumulated inside the flexible device) is not eliminated in time, it can adversely affect the screen assembly and the entire flexible screen device. The inventors have discovered that in some flexible screen devices with side frames made of insulating materials such as plastic (such as mobile phones with plastic frames), these devices inevitably come into contact with external structures and rub against each other during use, easily generating static electricity. Because the insulating side frames cannot be grounded, the static electricity generated by friction cannot be discharged in time, and at least some of it enters the interior of the screen assembly, adversely affecting the screen assembly and the entire flexible screen device. The inventors have also discovered that in some flexible screen devices with a front-facing camera, a whitish halo forms around the front-facing camera due to the accumulation of static electricity.

[0033] Therefore, this application provides a screen assembly and an electronic terminal. The screen assembly includes a display panel, a metal protective layer, and a flexible circuit board; the metal protective layer is located on the back side of the display panel, and the metal protective layer has at least two sub-protective areas spaced apart in a predetermined direction; the flexible circuit board has at least two protective connection circuits for respectively connecting the at least two sub-protective areas, and one of the at least two protective connection circuits is grounded. This structure, by setting the metal protective layer to have at least two sub-protective areas spaced apart in a predetermined direction and connecting them respectively through at least two protective connection circuits of the flexible circuit board, facilitates the provision of different input voltages to different sub-protective areas, and with one protective connection circuit grounded, allows a regular electric field to be formed on the back side of the screen assembly in the product, and the static charge is discharged through grounding, thereby effectively eliminating static electricity accumulated during the use of the screen assembly, such as static electricity accumulated during the operation of the screen assembly, and static electricity generated by friction between the screen assembly or the electronic terminal with the screen assembly and the external environment. For flexible screen terminals with a front-facing camera hole, it can also effectively eliminate the aperture formed around the front-facing camera hole due to the accumulation of static electricity.

[0034] The screen components mentioned here can be understood as flexible screen components, such as flexible AMOLED screen components.

[0035] The following is combined Figures 1 to 3 The screen components are described in detail.

[0036] Please refer to Figure 1 and combine when necessary Figure 2 and Figure 3As shown, the screen assembly 10 includes a cover plate 11, a display panel 12, a metal protective layer 13, and a flexible circuit board 14. The cover plate 11 and the metal protective layer 13 are located on opposite sides of the display panel 12. The metal is located on the back side of the display panel 12. The metal protective layer 13 has a first sub-protective area 131, a second sub-protective area 132, and a third sub-protective area 133 arranged at intervals in a predetermined direction. The flexible circuit board 14 has three protective connection circuits (not shown) for respectively connecting the first sub-protective area 131, the second sub-protective area 132, and the third sub-protective area 133, and one of the plurality of protective connection circuits is grounded.

[0037] Of course, in some other embodiments, the metal protective layer may also have two or more sub-protective areas spaced apart along a predetermined direction. Accordingly, the flexible circuit board has protective connection circuits for the user to connect a corresponding number of the two or more sub-protective areas respectively.

[0038] The display panel 12 has a front surface where the cover plate 11 is mounted and a back surface opposite the front surface. The front surface can be understood as the surface facing the user during use, and the back surface as the surface facing away from the user during use. The back side of the display panel 12, as mentioned here, refers to the side where the back surface of the display panel 12 is located. In the electronic terminal 100, the back side of the display panel 12 is generally located inside the electronic terminal 100.

[0039] The preset direction here can be understood as the width direction W of the screen component 10 (or the electronic terminal 100 having the screen component 10). Of course, in some other embodiments, the preset direction can also be other directions of the screen component 10, such as the length direction L.

[0040] The metal protective layer 13 here serves to support the display panel 12, prevent the screen assembly 10 from developing top marks, and dissipate heat. The metal protective layer 13 here can be copper foil.

[0041] It should be noted that in some embodiments, the flexible circuit board is provided with a grounding terminal, and the protective connection circuit used for grounding in the multiple protective connection circuits is directly connected to the grounding terminal.

[0042] Please combine Figure 3 As shown, in some embodiments, there is a spacer region 1031 with a preset width between each pair of adjacent sub-protection zones. The preset width d of the spacer region 1031 is 1mm-3mm, so as to maximize the protection area of ​​the protection zone while forming an electric field well. The preset width of the spacer region can be determined according to specific circumstances such as the voltage value of the input voltage required to be connected to each sub-protection zone.

[0043] For example, in some embodiments, the preset width d of the interval region 1031 can be 2mm.

[0044] In some embodiments, the sub-protection area and the protection connection circuit are connected via contacts. Specifically, corresponding connection contact keys can be provided between the sub-protection area and the corresponding protection connection circuit, and the two are connected via contacts during the assembly of the flexible circuit board 14.

[0045] In other embodiments, the two can also be connected by welding using electrical connection structures.

[0046] Please refer to Figure 4 and combine when necessary Figure 5 and Figure 6 As shown, this application also provides an electronic terminal 100, which includes a screen assembly 10 or a screen assembly similar to the screen assembly 10 described above, a control circuit board 20, and a power supply 30. The screen assembly similar to the screen assembly 10 mentioned here can be understood as a screen assembly with a metal protective layer having two or more sub-protective areas spaced apart along a predetermined direction.

[0047] The control circuit board 20 includes a control module 21, which is configured to control the connection between the at least two protective connection circuits other than the grounding protective connection circuit and the power supply 30, so that the metal protective layer 13 forms an electric field consistent with the preset direction, thereby effectively eliminating the static electricity accumulated during the use of the screen assembly.

[0048] The control circuit board mentioned here can be a PCB board. Taking a mobile phone as an example, the control circuit board can be at least one of the phone's motherboard or a small board.

[0049] It should be noted that for the flexible circuit board 14, which has a grounding terminal, the grounding terminal can be an auxiliary grounding terminal. Correspondingly, the control circuit board can have a main grounding terminal. This auxiliary grounding terminal can also be connected to the main grounding terminal of the electronic terminal through a connection circuit.

[0050] In some embodiments, the control circuit board 20 includes a boost module 22, the protective connection circuit is electrically connected to the power supply 30 through the boost module 22, and the control module 21 is configured to control the connection between the protective connection circuit other than grounding in the at least two protective connection circuits and the boost module 22.

[0051] For example, with Figure 3 The metal protective layer 13 shown is illustrated by taking as an example three sub-protective zones: a first sub-protective zone 131, a second sub-protective zone 132, and a third sub-protective zone 133.

[0052] If the second sub-protection zone 132 is grounded, the control module 21 is configured to control the connection between the protection connection circuits used to connect the first sub-protection zone 131 and the third sub-protection zone 133 and the boost module 22. Accordingly, the boost module 22 may have at least two different sub-boost modules to adjust the power supply voltage to at least two different voltages, such as -50V and 50V. The protection connection circuits used to connect the first sub-protection zone 131 and the third sub-protection zone 133 are respectively electrically connected to different sub-boost modules to provide different input voltages, such as -50V and 50V, to the first sub-protection zone 131 and the third sub-protection zone 133.

[0053] If the first sub-protection zone 131 is grounded, the control module 21 is configured to control the connection between the protection connection circuits used to connect the second sub-protection zone 132 and the third sub-protection zone 133 and the boost module 22. Accordingly, the boost module 22 may have at least two different sub-boost modules to adjust the power supply voltage to at least two different voltages, such as 5V and 10V. The protection connection circuits used to connect the second sub-protection zone 132 and the third sub-protection zone 133 are respectively electrically connected to different sub-boost modules to provide different input voltages, such as 5V and 10V, to the second sub-protection zone 132 and the third sub-protection zone 133.

[0054] In some embodiments, the metal protective layer 13 includes three or more sub-protective regions spaced sequentially along a preset direction, and the input voltage of the three or more sub-protective regions decreases or increases sequentially in the preset direction, thereby ensuring that the metal protective layer 13 forms an electric field consistent with the preset direction.

[0055] In some embodiments, the voltage difference between two adjacent sub-protective zones is equal, thus creating a more uniform electric field on the metal protective layer 13, resulting in better static electricity elimination. For example, similarly... Figure 3 Taking the metal protective layer 13 shown as having three sub-protective regions—a first sub-protective region 131, a second sub-protective region 132, and a third sub-protective region 133—as an example, in different embodiments, the input voltage of each sub-protective region can be as follows: Figure 6 The input voltages are shown in the table below. It should be noted that the three sub-protection zones 131, 132, and 133 can also be provided with other input voltage values, such as -3.3V, 0V, 3.3V, etc.

[0056] Of course, in some other embodiments, the voltage difference between two adjacent sub-protection zones may not be equal.

[0057] It should also be noted that the voltage difference between each sub-protection zone and the maximum input voltage supplied to each sub-protection zone can be set according to the specific situation of the static electricity that can be accumulated inside the electronic terminal.

[0058] In some embodiments, the flexible circuit board 14 has a display connection circuit for connecting the display panel 12, and the control module 21 is further configured to control the connection between the display connection circuit and the power supply 30.

[0059] In some embodiments, the control module 21 is further configured to control the protective connection circuit to be electrically connected to the power supply 30 at preset time intervals, so that the electric field formed by the metal protective layer 13 can be activated at preset time intervals. For example, the control module 21 may be configured to control the protective connection circuit to be electrically connected to the power supply 30 for 10 minutes every 50 minutes, so that the electric field formed by the metal protective layer 13 is activated for 10 minutes every 50 minutes.

[0060] In some embodiments, the control module 21 is further configured to control the protective connection circuit to be electrically connected to the power supply 30 when the display connection circuit is disconnected from the power supply 30 or after the disconnection time reaches a preset time, so that the electric field formed by the metal protective layer 13 can be turned on to eliminate static electricity when the display panel of the electronic terminal 100 is in a screen-off state.

[0061] In some embodiments, the control module 21 is further configured to control the protective connection circuit to be electrically connected to the power supply 30 within a preset time period. For example, the control module 21 is also configured to control the protective connection circuit to be electrically connected to the power supply 30 at night (e.g., between 21:00 and 6:00), so that the electric field formed by the metal protective layer 13 can eliminate static electricity at night.

[0062] In some embodiments, the electronic terminal 100 has a side bezel structure that surrounds the rear edge of the screen assembly 10. The side bezel structure is a plastic bezel.

[0063] For example, taking the electronic terminal 100 as a mobile phone, the side frame structure is a mid-frame structure.

[0064] In some embodiments, the screen assembly of the electronic terminal 100 is further provided with a camera hole that penetrates the metal protective layer 13 and the display panel 12.
