Background

With the improvement of the importance of electronic equipment in modern life, users pay more and more attention to the appearance of electronic equipment, and the concept of a comprehensive screen is deeply conscious and quickly becomes one of the mainstream directions of the development of the current electronic equipment. In order to reduce the occupation area of the front camera on the front side of the electronic equipment, a pole screen is generated.

The organic light-Emitting Diode (OLED) screen has a problem that the filled glue at the opening is "glue convex" due to the difficulty in handling the tolerance of the glue dispensing, so that the cover plate and the encapsulating layer (ENCAP) of the screen deform, and are equivalent to a positive lens, and the focal distance of the camera shifts toward the near-focus direction, thereby reducing the resolution of the camera.

Disclosure of Invention

The embodiment of the application aims to provide an electronic device, which can solve the problem that the focusing distance of a camera deviates to the near-focus direction because the tolerance of dispensing is difficult to grasp, so that the resolving power of the camera is reduced.

Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application may be practiced in sequences other than those illustrated or described herein, and that the terms "first," "second," and the like are generally used herein in a generic sense and do not limit the number of terms, e.g., the first term can be one or more than one. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.

Referring to fig. 1a, there is shown an opening position structure of a conventional pole screen, which includes, from top to bottom, a cover plate 01, an Optically Clear Adhesive (OCA) hard glue 02, an Optically Clear Resin (OCR) soft glue 03, a polarizer 04, a touch metal layer 05, an ENCAP layer 06, a spacer (PS) 07, a routing layer 08, an organic film 09, an inorganic film 010, and a Low Temperature Polysilicon (LTPS) layer 011 in sequence, where the polarizer 04, the touch metal layer 05, the spacer 07, the routing layer 08, the organic film 09, and the inorganic film 010 in a field of view are all removed, that is, an opening region 012 because a Clear aperture needs to be left for a camera.

Referring to fig. 1b, in an actual manufacturing process, the tolerance of the OCR soft rubber 03 is hard to be grasped, so that the glue at the opening is "glue convex", and the cover plate and the ENCAP of the screen are deformed, that is, a deformation region 013 shown in the figure is equivalent to a positive lens, so that the focus distance of the camera 014 is shifted toward the near focus direction, and the resolution of the camera 014 is reduced.

The electronic device provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

Referring to fig. 2, an embodiment of the present application provides an electronic device, which includes a screen 1 and a camera 2, and includes, at a position corresponding to the camera 2 on the screen 1, a cover plate 11, an adhesive layer 12, an optical filter 13, a packaging layer 14, a routing layer 15, and an LTPS layer 16, which are stacked from outside to inside;

in some embodiments, the screen 1 may be an OLED pole screen, where the position of the screen 1 corresponding to the camera 2 refers to an area of the screen 1 corresponding to the position of the camera 2, and for the pole screen, refers to an opening of the screen 1, where the opening refers to an opening in the internal structure of the screen 1 to expose the camera 2, instead of providing a through hole on the whole screen 1.

The optical filter 13 is positioned in the orthographic projection area of the camera 1 on the screen, and the optical filter 13 is used for filtering part of light in light rays entering the camera 2; in some embodiments, the optical filter 13 is an infrared filter, and functions to filter out infrared components of incident light.

The wiring layer 15 is provided with an opening 10, i.e. the area indicated by the dashed line in fig. 2, the opening 10 being located in the orthographic projection area of the camera 2 on the screen 1. In order to ensure that the camera 2 can receive light normally, it is necessary to ensure that there is no obstruction in the optical path of the camera 2, and therefore an opening 10 is provided in the routing layer 15 for the passage of incident light.

In the embodiment of the application, the optical filter is arranged inside the screen, the adhesive structure is adjusted, and compared with the existing equipment shown in fig. 1a and fig. 1b, the optical filter is used for replacing the original adhesive dispensing position, so that the problem that the camera is close to focus due to the convex phenomenon of the adhesive in the pole screen can be avoided.

Further, compared to the conventional apparatus shown in fig. 1a and 1b, the filter 015 of the conventional apparatus is located between the lens 014 and the imaging plane 016 (e.g. the position of the image sensor). In actual imaging, the optical filter can be regarded as a piece of flat glass, so that the back focal length of the lens is prolonged, and the height of the camera module is increased. For a specific comparison, see fig. 3, the optical filter 015 in the existing device is located in the camera 014, and compared with the case where the optical filter is disposed in the screen in the scheme of the embodiment of the present application, the position of the imaging surface 31 in the existing device is more backward than the position of the imaging surface 32 in the embodiment of the present application.

Therefore, the optical filter moves outwards, and the back focus of the lens can be shortened, so that the height of the camera is reduced, and the thickness of the whole machine is favorably reduced.

In some embodiments, the glue layer 12 is an OCR glue layer, or may also be referred to as an OCR soft glue. By virtue of the characteristic of fluidity of the OCR glue, the OCR glue fills the gap between the optical filter 13 and the hole in a flowing manner, prevents bubbles from occurring and avoids the problem of near focus caused by the convex phenomenon of the glue.

With continued reference to fig. 2, in some embodiments, the screen 1 further includes a polarizer 17, the polarizer 17 being positioned between the adhesive layer 12 and the encapsulation layer 14 and disposed around the optical filter 13.

With continued reference to fig. 2, in some embodiments, the screen 1 further includes a touch metal layer 18, and the touch metal layer 18 is located between the polarizer 17 and the encapsulation layer 14 and is disposed around the optical filter 13.

With continued reference to fig. 2, in some embodiments, the screen 1 further comprises: the isolation part 19, isolation part 19 are located between encapsulation layer 14 and routing layer 15, play the isolation effect, and are located camera 2 outside the orthographic projection area of screen 1, can avoid causing the sheltering from to camera 2's light path like this.

Specifically, as shown in fig. 2, the isolation portion 19 includes a plurality of isolation pillars that are uniformly distributed.

With continued reference to fig. 2, in some embodiments, the screen 1 further comprises: an organic film layer 20 and an inorganic film layer 21, wherein the organic film layer 20 and the inorganic film layer 21 are positioned between the routing layer 15 and the LTPS layer 16.

All set up trompil 10 on organic rete 20 and the inorganic rete 21, dotted line frame is regional in fig. 2 promptly, and the trompil is located camera 2 and is in the orthographic projection region of screen 1, can avoid causing the sheltering from like this to camera 2's light path.
