Referring to fig. 1 and 2, the display screen assembly 100 provided in the present application is a display screen of an electronic device 200 such as a mobile phone, an Ipad, etc., and the display screen assembly 100 includes a display screen 10 and a flexible printed circuit board 20 disposed on the display screen 10. It is understood that the flexible printed circuit board 20 is a highly reliable and excellent flexible printed circuit board made of polyimide or polyester film as a base material. The high-density light-weight LED lamp has the characteristics of high wiring density, light weight, thin thickness and good bending property. The flexible printed circuit board 20 serves as an intermediate medium for transmitting a current or an electrical signal, etc. required on the display screen 10 between the main circuit board or the sub circuit board in the electronic device 200 through the flexible printed circuit board 20.

Specifically, in one embodiment, the display screen 10 includes a display area 12 and a bezel area 14 disposed around the display area 12. The display area 12 is a region of the display panel 10 displaying a picture, and specifically, the display area 12 includes a plurality of scan lines 13-1 to 13-M (hereinafter referred to as 13), a scan driver (not shown) connected to the scan lines 13-1 to 13-M, a plurality of data lines 15-1 to 15-M (hereinafter referred to as 15) crossing the scan lines 13-1 to 13-M, a data driver (not shown) connected to the data lines 15-1 to 15-M, and pixel units 17 formed at crossing positions of the scan lines 13-1 to 13-M and the data lines 15-1 to 15-M. The scan driver sequentially generates scan signals on the scan lines 13-1 to 13-M, and the data driver generates corresponding data signals on the data lines 15-1 to 15-M to charge the pixel units 17 in the display panel, so as to generate corresponding frames. The flexible printed circuit board 20 is connected to the data driver on the display screen and the main circuit board or the sub circuit board outside the display screen 10, respectively.

In this embodiment, the display area 12 of the display screen 10 is provided with a functional hole 122, and the functional hole 122 is used for disposing some functional elements. Further, in one embodiment, the functional element disposed in the functional hole 122 includes at least one of a light sensing element, a camera assembly, and a flash. By adopting the structure, the display screen 10 does not need to reserve an extra large non-display area for accommodating the functional elements, and only a very small hole is reserved for the outer surface of the display screen 10 through which light can penetrate, so that the screen of the display screen 10 occupies a larger area.

In this embodiment, the first ground line 30 is disposed around the functional hole 122, and the first ground line 30 is connected to the flexible printed circuit board 20 on the display screen 10. Specifically, in one embodiment, the first grounding wire 30 has a portion forming a closed loop around the functional hole 122. In other embodiments, a closed loop may not be formed, but a gap 31 may be formed partially around the functional hole 122, as shown in fig. 3, as long as most of the static electricity around the functional hole 122 can be led away from the first grounding line 30 and grounded.

It can be understood that, with the above-mentioned structure, since at least one of the light sensing element, the camera assembly and the flash is disposed in the functional hole 122, during the use of the electronic device 200, for example, when the electronic device is shaken, bumped or dropped, the functional element in the functional hole 122 is easily displaced, or rubbed with an adjacent component product, or the functional elements collide with each other by a plurality of devices in the functional element itself, so that static electricity can be collected at the edge of the functional hole 122, or static electricity entering the electronic device 200 from an opening or an edge gap outside the electronic device 200 may also migrate to the edge of the functional hole 122. If the static electricity at the edge of the functional hole 122 is not led away and grounded, the display area 12 may be affected by the fuzzy display or the distorted color of the display in the area around the functional hole, and even if the static electricity at the edge of the functional hole 122 is relatively strong, one or more of the scan lines 13 or the data lines 15 may be damaged, so that the display screen 10 may appear black lines when displaying, and the display quality of the display screen 10 is greatly affected.

By arranging the first grounding wire 30 at the periphery of the functional hole 122, at least most of static electricity near the functional hole 122 can be led away for grounding, and the display effect that the display area 12 is located at the position of the functional hole 122 is better. It is understood that in the embodiment where the first ground line 30 forms a closed loop, the first ground line 30 is more effective in eliminating static electricity.

Optionally, in an embodiment, the functional hole 122 is one of a circle, an ellipse, or a quadrilateral. Specifically, in different examples, the shape of the functional hole 122 may be determined according to the size of the functional element disposed in the functional hole 122 or according to the appearance of the display screen 10. The functional holes 122 may be regular or irregular, and are not limited in particular.

Alternatively, in another embodiment, a plurality of functional holes 122 may be disposed in the display area 12, and the optical sensor element, the camera assembly, and the flash are separately disposed in one of the functional holes 122. It is understood that the functional element received in one functional hole 122 may also be a multi-functional integrated element, such as a three-in-one integrated sensor assembly including a light sensing element, a proximity sensor, and a digital converter, which is not limited in this respect.

Further, in various embodiments, the functional holes 122 may be located anywhere on the display area 12. In this embodiment, the functional holes 122 include at least two, one of which is used to accommodate the camera assembly, and the other functional holes are used to accommodate the optical sensing element, the proximity sensor or the three-in-one optical sensing element. In this embodiment, the functional hole 122 is located near the top of the display area 12. In other embodiments, the functional hole 122 may also be located at the bottom or at the edge of both sides of the display area 12, which is not particularly limited.

It will be appreciated that in embodiments where the functional aperture 122 is circular or oval, the first ground line 30 is at least partially radiused, i.e., the portion located near the periphery of the functional aperture 122 is radiused. The section of the first ground line 30 away from the functional hole 122 to which the flexible printed circuit board 20 is connected is a straight line. Further, in the embodiment where the functional hole 122 is circular or elliptical, the part of the data line 15 and the part of the scan line 13 near the functional hole 122 are located at the part of the arc transition of the periphery of the functional hole 122 to bypass the location of the functional hole 122.

Further, in an embodiment, the first ground line 30 is disposed closer to the functional hole 122 than the corresponding data line 15 and scan line 13 of the arc transition. By adopting the structure, the data line 15 or the scanning line 13 can be avoided from being separated between the first grounding line 30 and the functional hole 122, so that the first grounding line 30 can lead away a larger amount of static electricity at the position of the grounding functional hole 122, and the display effect of the display area 12 at the position of the functional hole is ensured. In other embodiments, a small amount of data lines 15 and/or scan lines 13 may be disposed between the first ground line 30 and the functional holes 122, as long as the first ground line 30 can lead away part of the static electricity around the functional holes 122, thereby ensuring the display effect of the display area 12 at the position of the functional holes 122.

In other embodiments, if the functional hole 122 is a quadrilateral or other irregular shape, the first ground line 30 and the scan line 13 closest to the functional hole 122 or the data line 15 closest to the functional hole 122 may not include a portion of circular arc transition, for example, a portion of the circular arc transition extends in a bending manner, as long as the functional hole 122 can be bypassed, and this is not particularly limited.

In another embodiment, the display screen 10 further includes a second ground line 40 disposed in the frame area 14, two ends of the second ground line 40 are respectively connected to the flexible printed circuit board 20, the second ground line 40 is disposed around the display area 12, and the first ground line 30 is connected to the second ground line 40. That is, the first ground line 30 includes a ring portion 32 surrounding the function hole 122, and an extension portion 34 having two ends respectively connected to the ring portion 32 and the second ground line 40, static electricity generated at the function hole 122 contacts the ring portion 32, is transmitted from the ring portion 32 to the extension portion 34, is transmitted from the extension portion 34 to the second ground line 40, is transmitted from the second ground line 40 to the flexible printed circuit board 20, and is finally discharged and grounded by the flexible printed circuit board 20. It can be understood that the extension portion 34 selects the position of the second ground line 40 closest to the functional hole 122 for connection, which can save the wiring length of the extension portion 34, make the structure simpler and save space. In other embodiments, the extension 34 may not be connected to the second ground line 40 located in the frame region 14, but the extension 34 may increase the length of the extension 34, and the extension 34 is directly connected to the flexible printed circuit board 20, which is not particularly limited.

The present application further provides an electronic device 200, wherein the electronic device 200 includes the display screen assembly 100 described in any of the above embodiments. The electronic device 200 may be a mobile phone, an IPad, an intelligent wearable device, a digital audio/video player, an electronic reader, a handheld game console, a vehicle-mounted electronic device, a digital camera, a printer, a flash drive, etc., which are not exhaustive and limited herein.

The above description is only for the purpose of illustrating embodiments of the present application and is not intended to limit the scope of the present application, and all modifications of equivalent structures and equivalent processes, which are made by the contents of the specification and the drawings of the present application or are directly or indirectly applied to other related technical fields, are also included in the scope of the present application.
