Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
The terms first, second and the like in the description and in the claims, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that embodiments of the application may be practiced otherwise than as specifically illustrated or described herein. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.
The electronic device provided by the embodiment of the application is described in detail below with reference to fig. 1 to 13 through specific embodiments and application scenarios thereof.
As shown in fig. 1 to 12, the electronic device according to the embodiment of the present application includes a foldable display screen, a first antenna, and a reflector 30, where the display screen has a folding area, and a first display screen 10 and a second display screen 20 located at two sides of the folding area, and the first display screen 10 and the second display screen 20 may be integrally formed; the first antenna 80 is disposed on the first display screen 10, and may be a millimeter wave antenna, where the first antenna includes a radiator 40 and a radio frequency circuit, and the radio frequency circuit is electrically connected to the radiator 40, and can feed signals into the radiator 40 through the radio frequency circuit, and radiate the fed signals through the radiator 40. The first antenna may be disposed in a non-display area or a display area of the first display screen 10, and the radiator 40 in the first antenna may be disposed on the cover plate of the first display screen 10, for example, disposed on an inner side of the cover plate. For example, the cover plate may be made of a flexible film or an ultra-thin glass (UTG), such as a polyimide film (CPI), and the radiator 40 may be coated on the inner surface of the CPI or UTG, so that the antenna is far away from the pixel circuit and the touch electrode, and the performance of the antenna is better. The reflector 30 is provided on the second display screen 20, and the reflector 30 may be provided on a non-display area or a display area of the second display screen 20, for example, the reflector 30 may be provided on a cover plate of the second display screen 20.
In the case that the first display screen 10 and the second display screen 20 are folded, the radiator 40 is spaced from the reflector 30, the first antenna and the reflector 30 form a second antenna, the signal radiated by the radiator 40 is radiated to the outside after being reflected by the reflector 30, and the signal radiated by the radiator 40 can be radiated to the outside after being reflected by the reflector 30, for example, the signal radiated by the radiator 40 can be radiated to the outside along the direction parallel to the first display screen 10 after being reflected by the reflector 30, so that the problem that the signal is not easy to radiate to the outside when the first display screen 10 and the second display screen 20 are folded is avoided. In the case where the first display 10 and the second display 20 are folded, end-fire radiation, such as radiation parallel to the screen direction, can be generated due to the reflector, without causing abrupt deterioration of antenna performance in the folded state. The cooperation of the radiator 40 and the reflector 30 can generate outwards-directed radiation parallel to the display screen, and the mobile phone can establish wireless communication connection with other intelligent terminals such as televisions, intelligent glasses, intelligent watches, VR/AR and the like, so that the user experience is improved. For example, video on a cell phone can be transmitted to a screen of the television 70 for playing, and high-speed high-definition video transmission, such as 4K and 8K video transmission, can be supported due to the fact that millimeter waves have an ultra-large bandwidth.
In the electronic device of the present application, the first antenna is disposed on the first display screen 10, the reflector 30 is disposed on the second display screen 20, and when the first display screen 10 and the second display screen 20 are folded, the signal of the first antenna can radiate to the outside through the reflection of the reflector 30, so as to avoid the performance degradation of the antenna when the first display screen 10 and the second display screen 20 are folded, and improve the performance of the antenna, so that the antenna can be used normally.

The radiator 40 may extend along a side of the first display screen 10, and the radiator 40 may be parallel to the side of the first display screen 10 to improve the performance of external radiation. The radiator 40, the director 50 and the reflector 30 may be respectively disposed on the inner side of the cover plate, and since the thickness of the cover plate (CPI or UTG of the flexible screen) is very thin, generally only tens to hundreds micrometers, it can be approximately considered that the strip-shaped reflector 30 and the radiator 40 of the dipole antenna are coplanar in the folded state, so as to form an approximately yagi antenna, so that the radiation direction is parallel to the screen and the radiation gain of the antenna parallel to the display screen is higher, and the antenna performance is not seriously deteriorated in the folded state, thereby improving the wireless communication experience in the folded state.
