When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1, the electronic device 10 will be described with reference to a smart phone as an example. Those skilled in the art will readily understand that the electronic device 10 of the present application may be any device having communication and storage functions, such as a smart terminal, for example, a smart phone, a tablet computer, a notebook computer, a mobile phone, a video phone, a digital still camera, an electronic book reader, a Portable Multimedia Player (PMP), a mobile medical device, etc., and the representation of the electronic device 10 is not limited herein.

The electronic device 10 includes a terminal body 100 and a touch module 200. In one embodiment, the terminal body 100 includes a housing assembly 110 and a display screen 120 connected to the housing assembly 110. The terminal body 100 is provided with a main board electrically connected to the display screen 120, and the main board can transmit signals to the display screen 120 to display information.

In one embodiment, the Display screen 120 may be a Liquid Crystal Display (LCD) screen for displaying information, and the LCD screen may be a Thin Film Transistor (TFT) screen or an In-Plane Switching (IPS) screen or a Liquid Crystal Display (SLCD) screen. In another embodiment, the display screen 120 may adopt an OLED (Organic Light-Emitting Diode) screen for displaying information, and the OLED screen may be an AMOLED (Active Matrix Organic Light-Emitting Diode) screen or a Super AMOLED (Super Active Matrix Organic Light-Emitting Diode) screen or a Super AMOLED Plus (Super Active Matrix Organic Light-Emitting Diode) screen, which will not be described herein again.

In one embodiment, the display 120 is a flexible display, and the display 120 can be folded and unfolded, in which case the electronic device 10 can be a foldable mobile terminal, such as a foldable mobile phone. In one embodiment, the housing assembly 110 includes a first housing 111 and a second housing 112, the display screen 120 is connected to the first housing 111 and the second housing 112, and the second housing 112 is rotatably connected to the first housing 111 to fold and unfold the display screen 120. For example, a folding mechanism 130 may be disposed between the first housing 111 and the second housing 112, and the second housing 112 can rotate relative to the first housing 111 through the folding mechanism 130. Referring to fig. 1, when the electronic device 10 is unfolded, the electronic device 10 has an effect of a large screen display. Referring to fig. 2, when the electronic device 10 is folded, the display screen 120 is exposed out of the first casing 111 and the second casing 112, so that the user can still use the electronic device 10 normally when the electronic device 10 is folded. It is understood that in other embodiments, when the electronic device 10 is folded, the display screen 120 may be hidden between the first housing 111 and the second housing 112, so that the display screen 120 is not exposed, and the display screen 120 may be in the off-screen operation state.

In one embodiment, as shown in fig. 1 and 2, the display screen 120 includes a first display area 121 and a second display area 122, the first display area 121 is connected to the first housing 111, and the second display area 122 is connected to the second housing 112. When the display screen 120 is folded, the first display area 121 is disposed opposite to the second display area 122. The areas of the first display region 121 and the second display region 122 may be the same or different.

Referring to fig. 1 and 3, the touch module 200 is rotatably connected to the terminal body 100, so that the touch module 200 is attached to the display screen 120 (shown in fig. 3) or detached from the display screen 120 (shown in fig. 1). The touch module 200 is electrically connected to the motherboard and can transmit a control command to the motherboard through a touch (i.e., a change in capacitance) sensed by the touch module 200 to perform information display of the display screen 120.

In one embodiment, referring to fig. 4, the touch module 200 includes a transparent substrate 210, a first touch unit 220 and a second touch unit 230. The transparent substrate 210 has a first surface 211 and a second surface 212 opposite to each other, and the material of the transparent substrate 210 may be selected from one of glass, polymethyl Methacrylate (PMMA), Polycarbonate (PC), Polyethylene terephthalate (PET), Cyclic Olefin Copolymer (COC), and Cyclic Olefin Polymer (COP).

For example, in an embodiment, the electronic device 10 includes a flexible circuit board 300 (shown in fig. 1), one end of the flexible circuit board 300 is electrically connected to the first touch unit 220, and an end of the flexible circuit board 300 opposite to the first touch unit 220 is electrically connected to the motherboard, for example, when the motherboard is disposed inside the first housing 111, the flexible circuit board 300 passes through the first housing 111 to be electrically connected to the motherboard, and when the motherboard is exposed out of the first housing 111, the flexible circuit board 300 may be directly electrically connected to the motherboard. Since the flexible circuit board 300 has a better bending performance, it is able to avoid the poor electrical contact between the touch module 200 and the motherboard during the rotation process. The first touch unit 220 has a first capacitive contact for detecting touch information of a user, and when the user touches the first touch unit 220, the first capacitive contact generates an electrical signal, and the signal is transmitted to a motherboard, specifically to a controller on the motherboard, and the motherboard controls the display screen 120 to display corresponding content according to the electrical signal.

For example, in an embodiment, the electronic device 10 includes a flexible circuit board 300 (shown in fig. 1), one end of the flexible circuit board 300 is electrically connected to the second touch unit 230, and one end of the flexible circuit board 300 opposite to the second touch unit 230 is electrically connected to the motherboard, for example, when the motherboard is disposed inside the first housing 111, the flexible circuit board 300 passes through the first housing 111 to be electrically connected to the motherboard, and when the motherboard is exposed out of the first housing 111, the flexible circuit board 300 may be directly electrically connected to the motherboard. Since the flexible circuit board 300 has a better bending performance, it is able to avoid the poor electrical contact between the touch module 200 and the motherboard during the rotation process. The second touch unit 230 has a second capacitive contact for detecting user touch information, and when the user touches the second touch unit 230, the second capacitive contact generates an electrical signal, and the signal is transmitted to a motherboard, specifically to a controller on the motherboard, and the motherboard controls the display screen 120 to display corresponding content according to the electrical signal.

Since both the first touch unit 220 and the second touch unit 230 can detect the touch information of the user, the dual-sided touch operation can be implemented on the touch module 200. When the touch module 200 rotates relative to the terminal body 100 and is attached to the display screen 120, a side of the first touch unit 220 opposite to the second touch unit 230 is attached to the display screen 120. When the touch module 200 rotates relative to the terminal body 100 and is attached to and detached from the display screen 120, the side of the first touch unit 220 opposite to the second touch unit 230 is no longer attached to the display screen 120.

Accordingly, the user can attach the first touch unit 220 to the display screen 120 and detach the first touch unit from the display screen 120 according to the use requirement. When the side of the first touch unit 220 opposite to the second touch unit 230 is separated from the display screen 120, as shown in fig. 1 for example, when the touch module 200 is unfolded relative to the display screen 120, a user can perform touch operation on the side of the first touch unit 220, so as to avoid the user shielding the display content of the display screen 120 during the touch operation, which is beneficial to achieving human-computer interaction and improving the user experience. When the user finds that the side of the first touch unit 220 opposite to the second touch unit 230 is separated from the display screen 120, which may cause the electronic device 10 to be too large to be held, the user may attach the side of the first touch unit 220 opposite to the second touch unit 230 to the display screen 120 (shown in fig. 3), and at this time, the user may perform a touch operation on the side of the second touch unit 230. Since the touch module 200 is transparent, the content displayed on the display screen 120 can be viewed through the touch module 200.

In an embodiment, the display screen 120 is a flexible screen, and the touch module 200 can rotate relative to the terminal 100 body, so that the first touch unit 220 is attached to and covers the first display area 121 on a side opposite to the second touch unit 230. For example, in an embodiment, when the first touch unit 220 is attached to and covers the first display area 121 on a side opposite to the second touch unit 230, the first display area 121 can display an electronic virtual keyboard, and the second touch unit 230 can detect touch information corresponding to the electronic virtual keyboard and transmit the touch information to the main board to perform information display in the second display area 122. At this time, the electronic device 10 may be used as a notebook computer, and for example, as shown in fig. 5, in order to adapt to the usage habit of the user, the second display area 122 and the first display area 121 may be arranged at an included angle in the process of the electronic device 10 from the folded state to the unfolded state.

In an embodiment, referring to fig. 1, the touch module 200 includes a frame 201, the frame 201 has a hollow structure with two open ends, the frame 201 is used to enclose the transparent substrate 210, the first touch unit 220 and the second touch unit 230 in the hollow structure, and the touch module 200 is rotatably connected to the first housing 111 through the frame 201. In an embodiment, the electronic device 10 includes a hinge 400, the touch module 200 is located on a side of the first housing 111 opposite to the second housing 112, and the frame 201 is rotatably connected to the first housing 111 through the hinge 400. Thus, the reliability of the rotation process of the touch module 200 relative to the first housing 111 is ensured.

In an embodiment, in order to avoid interference when the first touch unit 220 and the second touch unit 230 operate simultaneously, when the side of the first touch unit 220 opposite to the second touch unit 230 is attached to the display screen 120, the first touch unit 220 is electrically disconnected from the main board, and the second touch unit 230 is electrically connected to the main board, at this time, a touch operation can be performed on the second touch unit 230. When the side of the first touch unit 220 opposite to the second touch unit 230 is separated from the display screen 120, the first touch unit 220 is electrically connected to the main board, and the second touch unit 230 is electrically disconnected from the main board, so that the touch operation can be performed on the first touch unit 220. For example, in one embodiment, the first touch unit 220 has a first contact, the second touch unit 230 has a second contact, and the main board has a third contact. When the first touch unit 220 is attached to the display screen 120 at a side opposite to the second touch unit 230, the first contact is spaced from the third contact, and the second contact is in contact with the third contact to electrically connect the second touch unit 230 with the main board. When the side of the first touch unit 220 opposite to the second touch unit 230 is separated from the display screen 120, the second contact is spaced from the third contact, and the first contact is in contact with the third contact to electrically connect the first touch unit 220 with the main board.

The hardened layer 240 disposed on the second surface 212 is defined as a second hardened layer 242, and the second hardened layer 242 is disposed between the second surface 212 and the second touch unit 230. It is understood that in other embodiments, the number of the hardened layers 240 may be one, and in this case, the hardened layers 240 may be disposed on the first surface 211 of the transparent substrate 210 or disposed on the second surface 212 of the transparent substrate 210.

In an embodiment, the touch module 200 further includes an optical anti-reflection layer 250, and the optical anti-reflection layer 250 is an image removing film (IM film). The optical anti-reflection layer 250 can generate certain optical interference characteristics by overlapping high and low refractive index dielectric film materials and film thicknesses with different lambda/4 multiples, thereby realizing the improvement of light transmittance.

In one embodiment, the number of optical anti-reflection layers 250 is two, the optical anti-reflection layer 250 disposed between the first surface 211 and the first touch unit 220 is defined as a first optical anti-reflection layer 251, and the optical anti-reflection layer 250 disposed between the second surface 212 and the second touch unit 230 is defined as a second optical anti-reflection layer 252.

The first optical anti-reflection layer 251 may be formed on the first hardened layer 241 by means of magnetron sputtering, and the second optical anti-reflection layer 252 may be formed on the second hardened layer 242 by means of magnetron sputtering. When the touch film assembly 200 is not provided with the hardening layer 240, the first hardening layer 241 is directly formed on the first surface 211, and the second hardening layer 242 is directly formed on the second surface 212.

In an embodiment, the touch module 200 further includes a first insulating protective layer 261, i.e., a PAS layer, where the first insulating protective layer 261 is disposed on a side of the first touch unit 220 opposite to the transparent substrate 210, so as to effectively prevent the first touch unit 220 from being scratched by a foreign object.
