[0002] With the popularity of touch screens, existing smart phones, tablet computers and some home appliances with screens generally support the use of screen touch keyboards for text input. In the early days, most of them were resistive screens, but as the cost decreases, capacitive screens now account for the majority. Its characteristics are that text input can be achieved without adding a physical keyboard, the keyboard display is intuitive, and the interface can be freely customized.

[0003] However, the screen touch keyboard is displayed directly on a flat screen interface, so when users press a key, there is no key travel feedback of a traditional physical keyboard, and the feel is poor, which leads to users who are accustomed to traditional physical keyboards generally not being accustomed to using the screen touch keyboard, affecting the user experience. Due to the lack of touch feedback, users are also prone to accidentally press the position between two keys, which is easy to cause mis-input and affects the user experience. And the need to observe the position of the key at all times also affects the user experience for people with limited vision. Summary of the invention

However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present application more thorough and comprehensive.

[0041] As used herein, "electronic device" refers to a device that can receive and / or send communication signals, including but not limited to a device that is connected via any one or more of the following connection methods:

[0042] (1) Connection via wired lines, such as Public Switched Telephone Networks (PSTN), Digital Subscriber Line (DSL), digital cable, and direct cable connection;

[0043] (2) Via wireless interfaces, such as cellular networks, wireless local area networks (WLAN), digital television networks such as DVB-H networks, satellite networks, and AM-FM broadcast transmitters.

[0044] An electronic device configured to communicate via a wireless interface may be referred to as a "mobile terminal". Examples of mobile terminals include, but are not limited to, the following electronic devices:

[0045] (1) Satellite phone or cellular phone;

[0046] (2) Personal Communications System (PCS) terminals that can combine cellular radio telephones with data processing, fax, and data communications capabilities;

[0048] (4) conventional laptop and / or palmtop receivers;

[0049] (5) Conventional laptop and / or palmtop radio telephone transceivers, etc.

[0050] See also Figure 1 As shown, an electronic device 100 provided in one embodiment of the present application can be a mobile phone or a tablet computer, which is not limited here. The electronic device 100 includes a device body 10, a screen 20 and a screen film 30. The screen 20 is mounted on the body and provides display and touch functions. The screen film 30 is attached to the outer surface 20a of the screen 20.

[0051] It should be noted that, combined with Figure 2 As shown, the screen film 30 can be attached to the screen 20 and sold together as a display screen, that is, the display screen includes the screen 20 with the screen film 30 attached.

[0052] In other embodiments, the screen film 30 may also be sold separately as an accessory. When it needs to be adhered to the screen 20 for use, it only needs to be bonded to the outer surface 20a of the screen 20, and no limitation is made here.

[0053] Combination Figure 3 As shown, the screen film 30 includes an adhesive layer 31 and an air-filled layer 32, wherein the adhesive layer 31 is used to adhere to the outer surface 20a of the screen 20. The air-filled layer 32 is connected to the screen 20 through the adhesive layer 31. The adhesive layer 31 can be a glue layer formed by transparent glue, or a transparent film layer, and the adsorption force between the transparent film layer itself and the screen 20 is used to achieve a stable connection with the screen 20. The air-filled layer 32 can be connected to the side of the adhesive layer 31 away from the screen 20. In some embodiments, when the adhesive layer 31 is a glue layer formed by transparent glue, the transparent glue can be applied to the air-filled layer 32, so that the adhesive layer 31 can be formed on the surface of the air-filled layer 32 by using the transparent glue. In some embodiments, when the adhesive layer 31 is a transparent film layer, the transparent film layer and the air-filled layer 32 can be connected together by laminating or gluing, so that when the screen film 30 needs to be attached to the screen 20, the adhesive layer 31 can be used to stably connect the screen film 30 to the screen 20 as a whole.

[0054] Combination Figure 4 As shown, the inflatable layer 32 includes a plurality of capsule units 321, for example, 2 or more capsule units 321, and the number and position of these capsule units 321 can be configured according to actual needs. For example, when these capsule units 321 are inflated to provide a pressing tactile sensation for the virtual keys of the screen 20, the capsule units 321 can be set corresponding to the arrangement of the virtual keys when the screen 20 displays the virtual keys.

[0055] It should be noted that the inflatable layer 32 may be composed of a double-layer elastic film 32a, and then when gas is injected between the double-layer elastic film 32a, the elastic film 32a can be deformed so that the part constituting the capsule unit 321 is inflated and bulged, so that the expanded capsule units 321 can be used to simulate physical buttons to provide a better pressing touch feeling for the touch operation. In other embodiments, the inflatable layer 32 may also be a single-layer elastic film 32a, for example, the single-layer elastic film 32a is connected to the adhesive layer 31 to form the above-mentioned multiple capsule units 321, that is, part of the single-layer elastic film 32a is sealed and connected to the adhesive layer 31, and part is not connected to the adhesive layer 31 to form the capsule unit 321. In some other embodiments, the adhesive layer 31 of the present application has a plurality of hollow portions corresponding to a plurality of bladder units 321, so that when the single-layer elastic film 32a is connected to the outer surface 20a of the screen 20 by using the adhesive layer 31, the portion of the single-layer elastic film 32a corresponding to the hollow portions will be in an unconnected state between the screen 20, and then the bladder units 321 that can be inflated and expanded are formed. The specific formation method and structural form of the inflation layer 32 will not be described in detail again, as long as the bladder units 321 that can be inflated and deflated can be formed.

[0056] The plurality of capsule units 321 are arranged at intervals so that they do not interfere with each other when pressed. Thus, for the screen 20 with the screen film 30 attached thereto, when a touch operation is performed on a position corresponding to a capsule unit 321, the position corresponding to an adjacent capsule unit 321 will not be touched by mistake.

[0057] Combination Figure 3 and Figure 4 As shown, each bladder unit 321 has an inflated state and an uninflated state. Figure 3 The uninflated state of the capsule unit 321 is shown. Specifically, when the capsule unit 321 is in the uninflated state, the inflation layer 32 is flatly attached to the side of the adhesive layer 31 facing away from the screen 20 , so that the capsule unit 321 at this time will not affect the normal display effect and sliding operation effect of the screen 20 . Figure 4 The inflated state of the capsule unit 321 is shown. Specifically, when the multiple capsule units 321 are in the inflated state, the positions of the corresponding multiple capsule units 321 of the inflatable layer 32 are protruding relative to other positions. At this time, the protruding capsule units 321 can be used to provide a real touch feeling during the press touch operation, thereby improving the press touch operation experience. For example, when performing a touch operation on a virtual key, the finger presses the protruding capsule unit 321, and the capsule unit 321 is squeezed and can adapt to the deformation, so that the user can obtain the key travel feedback effect of a physical keyboard, and the pressing feel is good. In addition, this method of squeezing the capsule unit 321 to achieve the key effect effectively reduces the probability of incorrect input information due to mis-touch, compared with directly touching the screen 20, and greatly improves the operating feel and reliability of the press touch.

[0058] Combination Figure 5 As shown, multiple capsule units 321 are connected to each other through the ventilation channel 322. When the multiple capsule units 321 are in an inflated state, during the process of pressing the capsule unit 321, the capsule unit 321 presses against the screen 20 through the adhesive layer 31, and the capsule unit 321 discharges gas to other capsule units 321 through the ventilation channel 322. In this way, the pressing operation of the currently pressed capsule unit 321 has a process of the component releasing its internal gas, thereby obtaining a good touch during the pressing stroke.

[0059] In some embodiments, in combination Figure 6 As shown, the screen film 30 further includes a protective layer 33, which is stacked on the side of the inflation layer 32 facing away from the adhesive layer 31 to provide protection for the inflation layer 32. The protective layer 33 can be a scratch-resistant film, which can improve the service life of the entire screen film 30.

[0060] It should be noted that when the inflation layer 32 is filled with gas to expand the multiple capsule units 321, the position of the protective layer 33 corresponding to the capsule unit 321 protrudes relative to other positions, so that the protective layer 33 adopted will not affect the normal expansion of the capsule unit 321 when inflated, ensuring that the capsule unit 321 provides a good touch for the press touch operation of the screen 20 when inflated.

[0061] In some embodiments, the virtual buttons enabled when the screen 20 is in landscape display or portrait display correspond one-to-one to the multiple capsule units 321 of the inflatable layer 32, thereby utilizing the inflated capsule units 321 to provide a good touch feel for the pressing touch operation of the corresponding virtual buttons, thereby improving the user experience.

[0062] continue Figure 6 As shown, in some embodiments, the screen film 30 includes multiple inflatable layers 32, and the multiple inflatable layers 32 are stacked, so that the multiple inflatable layers 32 can be used to meet the needs of different press touch scenes. The capsule units 321 located in different inflatable layers 32 are not connected to each other to avoid mutual interference between different inflatable layers 32 when providing a good touch feeling for the screen 20.

[0063] Among the multiple inflatable layers 32, at least two inflatable layers 32 have different arrangements of the capsule units 321, that is, when the screen film 30 is attached to the screen 20 for use, the capsule units 321 located in different inflatable layers 32 are located at different positions. Figure 7 and Figure 8 The arrangement of the capsule units 321 on two different inflatable layers 32 is shown respectively. Figure 7 and Figure 8 As shown, when the bladder units 321 are inflated, the arrangement positions of the bladder units 321 in different inflation layers 32 are different.

[0064] This different arrangement can be used to adapt to different scenarios of press touch operations. Figures 9 to 12 As shown, for the screen 20 displaying virtual keys, when the screen 20 is in the horizontal screen state (refer to Fig. 9 and Fig.10 ) and vertical screen state (reference Fig. 9 and Fig.10 ), the position of the virtual button will also rotate with the screen 20 display image. In this way, different inflatable layers 32 are used to correspond to the positions of the virtual buttons in the horizontal and vertical states of the screen 20 respectively. The corresponding capsule units 321 can adapt to the press and touch operations in the horizontal and vertical scenes of the screen 20 and enhance the touch feeling.

[0065] In some embodiments, the screen 20 includes a touch display module and a cover plate, and the cover plate is covered on the display side of the touch display module. In this embodiment, the air filling layer 32 is connected to the side of the cover plate facing away from the touch display module through the adhesive layer 31.

[0066] In the embodiment where the screen film 30 includes a plurality of air-filled layers 32 , the air-filled layers 32 may be two layers or more than two layers, which is not limited herein.

[0067] The multiple capsule units 321 of at least one inflatable layer 32 correspond one-to-one to the virtual keys enabled when the screen 20 is in landscape display, and the multiple capsule units 321 of at least one inflatable layer 32 correspond one-to-one to the virtual keys enabled when the screen 20 is in portrait display.

[0068] For example, in some embodiments, the screen film 30 includes two inflatable layers 32, the two inflatable layers 32 are stacked, and the capsule units 321 located in different inflatable layers 32 are not connected to each other, and the multiple capsule units 321 of one inflatable layer 32 correspond one-to-one to the virtual keys enabled when the screen 20 is in landscape display, so as to meet the need for enhanced tactile sensation of pressing and touching operations on the virtual keys of the screen 20 in the landscape state; the multiple capsule units 321 of the other inflatable layer 32 correspond one-to-one to the virtual keys enabled when the screen 20 is in portrait display, so as to meet the need for enhanced tactile sensation of pressing and touching operations on the virtual keys of the screen 20 in the portrait state.

[0069] In some embodiments, the inflatable layer 32 is connected to an air supply unit, and the device body 10 includes a control chip, which is communicatively connected to the screen 20 and the air supply unit. When the control chip controls the screen 20 to display virtual keys, the control chip controls the air supply unit to inflate the inflatable layer 32, so that the multiple capsule units 321 of the inflatable layer 32 change from an uninflated state to an inflated state. In this way, when the control chip calls the screen 20 to display virtual keys, the corresponding inflatable layer 32 can be inflated in time, so as to utilize the capsule units 321 to enhance the pressing touch of the virtual keys during the touch operation.

[0070] The air supply unit may be a device disposed inside the electronic device 100 or outside the electronic device 100, which is not limited here.

[0071] In some embodiments, the gas supply unit includes a gas tank and a valve, and the valve is communicatively connected to the control chip. When the control chip controls the screen 20 to display a virtual key, the control chip controls the valve to open, so that the gas tank supplies gas to the inflation layer 32, and then the multiple capsule units 321 are in an inflated state, providing a good touch for the pressing and touching operation of the virtual key, thereby improving the user experience.

[0072] In other embodiments, the air supply unit includes an air pump, and the air pump is communicatively connected to the control chip, so that the control chip can inflate and deflate the air-filled layer 32 by controlling the air pump.

[0073] It should be noted that the gas filled into the capsule unit 321 of the inflation layer 32 is not limited to air, and may also be clean gas such as argon, helium, etc., to prevent dust from accumulating in the inflation layer 32 and affecting the use effect of the screen film 30.

[0074] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0075] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
