Description

Technical Field

[0001] The present application relates to the technical field of display devices, and in particular to a display device and a smart terminal. Background Art

[0002] Foldable screen devices are currently very popular among users. They consist of a protective assembly, a flexible screen, a support plate that supports the flexible screen, and a foldable housing. The protective assembly comprises a stacked protective layer and a cover layer, covering the flexible screen. The flexible screen is attached to the support plate, which is then attached to the housing via an adhesive layer. The housing can be folded or unfolded around a pivoting hinge. To conceal the appearance and prevent dust, a black strip is applied to the edge of the protective assembly and the housing.

[0003] During the process of conceiving and implementing this application, the inventor discovered that there are at least the following problems: in order to provide sufficient protection for the flexible screen, the protective component needs to have a certain structural strength, but if the structural strength of the protective component is too great, it will generate a large rebound force when the folding screen device is in a folded state, which is not conducive to the hovering of the folded part, and therefore the screen reliability is not high; since the bending radius of the protective component is large, it is not conducive to the lightweight and thinning of the folding screen device, and the crease of the folding screen device is relatively obvious.

[0056] Figure 1 For a hardware structure diagram of a mobile terminal implementing each embodiment of the present application, please refer to Figure 1 , which is a schematic diagram of the hardware structure of a smart terminal for implementing various embodiments of the present application. The smart terminal 100 may include: an RF (Radio Frequency) unit 101, a WiFi module 102, an audio output unit 103, an A / V (audio / video) input unit 104, a sensor 105, a display unit 106, a user input unit 107, an interface unit 108, a memory 109, a processor 110, and a power supply 111. Those skilled in the art will understand that Figure 1 The structure of the smart terminal shown in the figure does not constitute a limitation on the smart terminal. The smart terminal may include more or fewer components than shown in the figure, or combine certain components, or arrange the components differently.

[0057] The following combination Figure 1 A detailed introduction to each component of the smart terminal:

[0058] The RF unit 101 can be used to send and receive information or receive signals during calls. Specifically, it receives downlink information from the base station and transmits it to the processor 110 for processing. It also transmits uplink data to the base station. Typically, the RF unit 101 includes, but is not limited to, an antenna, at least one amplifier, a transceiver, a coupler, a low-noise amplifier, a duplexer, and more. Furthermore, the RF unit 101 can communicate with the network and other devices via wireless communication. The above-mentioned wireless communications may use any communication standard or protocol, including but not limited to GSM (Global System of Mobile communication), GPRS (General Packet Radio Service), CDMA2000 (Code Division Multiple Access 2000), WCDMA (Wideband Code Division Multiple Access), TD-SCDMA (Time Division-Synchronous Code Division Multiple Access), FDD-LTE (Frequency Division Duplexing-Long Term Evolution), TDD-LTE (Time Division Duplexing-Long Term Evolution) and 5G, etc.

[0059] WiFi is a short-range wireless transmission technology. Smart terminals can help users send and receive emails, browse web pages, and access streaming media through WiFi module 102. It provides users with wireless broadband Internet access. Figure 1 The WiFi module 102 is shown, but it is understandable that it is not an essential component of the smart terminal and can be omitted as needed without changing the essence of the utility model.

[0060] The audio output unit 103 can convert audio data received by the RF unit 101 or the WiFi module 102 or stored in the memory 109 into an audio signal and output it as sound when the smart terminal 100 is in a call signal reception mode, a call mode, a recording mode, a voice recognition mode, a broadcast reception mode, or the like. Furthermore, the audio output unit 103 can also provide audio output related to a specific function performed by the smart terminal 100 (e.g., a call signal reception sound, a message reception sound, etc.). The audio output unit 103 may include a speaker, a buzzer, or the like.

[0061] The A / V input unit 104 is used to receive audio or video signals. The A / V input unit 104 may include a graphics processing unit (GPU) 1041 and a microphone 1042. The GPU 1041 processes image data of still images or videos captured by an image capture device (e.g., a camera) in video capture mode or image capture mode. The processed image frames may be displayed on the display unit 106. The image frames processed by the GPU 1041 may be stored in the memory 109 (or other storage medium) or transmitted via the RF unit 101 or the WiFi module 102. The microphone 1042 may receive sound (audio data) in operating modes such as a phone call mode, a recording mode, and a voice recognition mode, and may process such sound into audio data. In the phone call mode, the processed audio (voice) data may be converted into a format that can be transmitted to a mobile communication base station via the RF unit 101. The microphone 1042 may implement various types of noise cancellation (or suppression) algorithms to eliminate (or suppress) noise or interference generated during the reception and transmission of audio signals.

[0062] The smart terminal 100 also includes at least one sensor 105, such as a light sensor, a motion sensor, and other sensors. Optionally, the light sensor includes an ambient light sensor and a proximity sensor. Optionally, the ambient light sensor can adjust the brightness of the panel 1061 according to the brightness of the ambient light, and the proximity sensor can turn off the panel 1061 and / or the backlight when the smart terminal 100 is moved to the ear. As a type of motion sensor, the accelerometer sensor can detect the magnitude of acceleration in all directions (generally three axes), and can detect the magnitude and direction of gravity when stationary. It can be used for applications that recognize the posture of the mobile phone (such as horizontal and vertical screen switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer, tapping), etc.; as for other sensors that can be configured on the mobile phone, such as fingerprint sensors, pressure sensors, iris sensors, molecular sensors, gyroscopes, barometers, hygrometers, thermometers, infrared sensors, etc., they will not be described in detail here.

Optionally, the user input unit 107 may include a touch panel 1071 and other input devices 1072. The touch panel 1071, also known as a touch screen, can collect user touch operations on or near it (such as operations performed by the user using any suitable object or accessory such as a finger, stylus, etc. on or near the touch panel 1071) and drive the corresponding connection device according to a pre-set program. The touch panel 1071 may include two parts: a touch detection device and a touch controller. Optionally, the touch detection device detects the user's touch direction and detects the signal caused by the touch operation, and transmits the signal to the touch controller; the touch controller receives the touch information from the touch detection device and converts it into touch point coordinates, which are then sent to the processor 110. It can also receive commands sent by the processor 110 and execute them. In addition, the touch panel 1071 can be implemented using various types such as resistive, capacitive, infrared, and surface acoustic wave. In addition to the touch panel 1071, the user input unit 107 may further include other input devices 1072. Optionally, the other input devices 1072 may include, but are not limited to, one or more of a physical keyboard, function keys (such as volume control keys, power keys, etc.), a trackball, a mouse, a joystick, etc., and the specifics are not limited here.

[0065] Optionally, the touch panel 1071 may cover the flexible display panel 1061. When the touch panel 1071 detects a touch operation on or near it, it transmits the information to the processor 110 to determine the type of touch event. The processor 110 then provides a corresponding visual output on the panel 1061 according to the type of touch event. Figure 1 In the figure, the touch panel 1071 and the flexible display panel 1061 are two independent components to realize the input and output functions of the smart terminal. However, in some embodiments, the touch panel 1071 and the flexible display panel 1061 can be integrated to realize the input and output functions of the smart terminal, which is not limited here.

[0067] Memory 109 can be used to store software programs and various data. Memory 109 may primarily include a program storage area and a data storage area. Optionally, the program storage area may store an operating system and at least one application required for a function (such as a sound playback function or an image playback function); the data storage area may store data generated based on the use of the mobile phone (such as audio data, a phone book, etc.). Furthermore, memory 109 may include high-speed random access memory and non-volatile memory, such as at least one disk storage device, flash memory device, or other volatile solid-state storage device.

[0068] Processor 110 is the control center of the smart terminal, connecting all components of the smart terminal using various interfaces and circuits. By running or executing software programs and / or modules stored in memory 109 and accessing data stored in memory 109, it executes various functions of the smart terminal and processes data, thereby providing overall monitoring of the smart terminal. Processor 110 may include one or more processing units; preferably, processor 110 may integrate an application processor and a modem processor. Optionally, the application processor primarily processes the operating system, user interface, and application programs, while the modem processor primarily handles wireless communications. It is understood that the modem processor may not be integrated into processor 110.

[0069] The smart terminal 100 may also include a power supply 111 (such as a battery) to supply power to each component. Preferably, the power supply 111 may be logically connected to the processor 110 through a power management system, thereby managing charging, discharging, and power consumption through the power management system.

[0070] although Figure 1 Not shown, the smart terminal 100 may further include a Bluetooth module, etc., which will not be described in detail here.

HSS 2032 provides registers for managing functions such as the Home Location Register (not shown) and stores user-specific information such as service features and data rates. All user data can be sent through SGW2034, PGW2035 can provide IP address allocation and other functions for UE 201, PCRF2036 is the policy and charging control policy decision point for service data flow and IP bearer resources, and it selects and provides available policy and charging control decisions for the policy and charging execution function unit (not shown in the figure).

[0076] The IP service 204 may include the Internet, an intranet, an IMS (IP Multimedia Subsystem), or other IP services.

[0077] Although the above introduction takes the LTE system as an example, those skilled in the art should know that this application is not only applicable to the LTE system, but can also be applied to other wireless communication systems, such as GSM, CDMA2000, WCDMA, TD-SCDMA, 5G and future new network systems (such as 6G), etc., which are not limited here.

[0078] Based on the above-mentioned smart terminal hardware structure and communication network system, various embodiments of the present application are proposed.

[0079] First embodiment

[0080] Figure 3 is a schematic cross-sectional view of the display device according to the first embodiment of the present application. Figure 3 As shown, the display device includes a shell 12, a display screen assembly 13 arranged in the shell 12, and a cover plate 14 covering the display screen assembly 13. The display device includes a non-bending area and a bending area. The surface of the cover plate 14 corresponding to the bending area is concave to form an arc groove 301.

[0081] The cover plate 14 of the display device of the present application is formed with an arc-shaped groove 301 corresponding to the bending area, which can not only reduce the rebound force of the cover plate 14, which is beneficial to the hovering of the display device and the reliability of the screen, but also reduce the bending radius of the cover plate 14, which is beneficial to the lightweight display device, and can reduce creases and improve user experience.

[0082] It is worth mentioning that the non-bending area of ​​the display device refers to the area where the display device does not bend in the thickness direction when the display device is bent and folded; the bending area of ​​the display device refers to the area where the display device bends in the thickness direction when the display device is bent and folded.

[0083] Alternatively, as Figure 3 As shown, the non-bending zone includes a first non-bending zone 112, a second non-bending zone 113, a third non-bending zone 114, and a fourth non-bending zone 115, and the bending zone includes a first bending zone 116, a second bending zone 117, and a third bending zone 118. The first non-bending zone 112, the first bending zone 116, the second non-bending zone 113, the second bending zone 117, the third non-bending zone 114, the third bending zone 118, and the fourth non-bending zone 115 are connected in sequence, and the second bending zone 117 of the cover plate 14 is formed with an arc-shaped groove 301. In this embodiment, the housing 12 and the display screen assembly 13 both include a first non-bending zone 112, a first bending zone 116, a second non-bending zone 113, a second bending zone 117, a third non-bending zone 114, a third bending zone 118, and a fourth non-bending zone 115 connected in sequence.

Figure 3 and Figure 4As shown, the cover plate 14 includes a first surface 141 and a second surface 142 disposed opposite each other, with an arcuate groove 301 formed on the second surface 142. The display device also includes a first adhesive layer 16 disposed on the first surface 141. In this embodiment, the first adhesive layer 16 is a resin adhesive; the first adhesive layer 16 can absorb some impact force, providing a good cushioning effect, protecting the cover plate 14 and the display assembly 13 thereunder, and improving the reliability of the display device. In addition, the first adhesive layer 16 can be flattened, and the rebound force of the cover plate 14 can be adjusted by adjusting the modulus of the first adhesive layer 16.
