Description

Technical Field

[0001] This application relates to the field of smart terminals, specifically to a display module and a smart terminal having the aforementioned display module. Background Technology

[0002] With the development of mobile devices, displays equipped with POL-Less technology have become popular. However, during the conception and implementation of this application, the inventors discovered shortcomings in the existing technology. Displays equipped with POL-Less technology require openings in the non-light-emitting area of ​​the BM layer at the light-sensing aperture, allowing external light to pass through the panel and reach the light sensor. The light sensor receives different light intensities and transmits them to the display components to achieve automatic brightness adjustment. To ensure a seamless black effect on the device screen, the opening size of the BM layer often needs to be reduced. However, once the opening size is reduced, the field of view (FOV) of the ambient light sensor is reduced due to the size of the opening. The light sensor then cannot sensitively detect ambient light brightness and cannot adjust the screen brightness accordingly, thus affecting the user experience. Utility Model Content

[0003] The purpose of this application is to provide a display module and a smart terminal that can improve the FOV of a POL-Less screen and enhance the timeliness and accuracy of screen brightness changes with ambient light.

[0004] To address the aforementioned technical problems, this application provides a display module, including a display unit, a control unit electrically connected to the display unit, a light sensor disposed on the back of the display unit and electrically connected to the control unit, and a refractive assembly disposed between the display unit and the light sensor. The display unit has a light-transmitting hole, the light sensor is used to receive light passing through the light-transmitting hole and generate a corresponding sensing signal, and the control unit is used to adjust the brightness of the display unit according to the sensing signal. The refractive assembly is used to refract the light passing through the light-transmitting hole toward the center of the display unit to increase the amount of light received by the light sensor.

[0005] Furthermore, the refractive component includes a lens body on which a concave lens array is formed.

[0006] Furthermore, the concave lens array is disposed on the side of the lens body facing the light sensor, and the surface of the lens body facing the display unit is flat.

[0007] Furthermore, the display unit includes a panel layer for displaying images electrically connected to a light sensor, and a black matrix disposed in the panel layer, with light-transmitting holes penetrating the black matrix.

[0008] Furthermore, the display unit also includes a flexible under-display support film attached to one side surface of the panel layer and a foldable screen support layer bonded to the flexible under-display support film, with the refractive component bonded to the foldable screen support layer.

[0009] Furthermore, the display unit also includes an optically transparent film attached to the other side surface of the panel layer and a flexible cover plate attached to the optically transparent film.

[0010] Furthermore, the display unit also includes an adhesive layer that bonds the lens body to the foldable screen support layer, and the adhesive layer has vent holes for communicating the space between the panel layer and the refractive component with the outside.

[0011] Furthermore, the lens body includes a lens portion having a concave lens array and a connecting portion formed around the lens portion. The thickness of the connecting portion is less than the thickness of the lens portion, and the connecting portion is bonded to the display unit.

[0012] Furthermore, the display unit also includes a flexible under-display support film attached to one side surface of the panel layer, an adhesive layer bonded to the flexible under-display support film, and a foldable screen support layer bonded to the adhesive layer. Both the adhesive layer and the foldable screen support layer are made of transparent material, and the light-refractive component is a concave lens array formed on the foldable screen support layer.

[0013] This application also provides a smart terminal, including the aforementioned display module.

[0014] This application provides a display module and a smart terminal. The display module includes a display unit, a light sensor, and a refractive assembly. The refractive assembly is disposed between the display unit and the light sensor. The refractive assembly includes a lens body with a concave lens array on the lens body. By setting the refractive assembly, large-angle light is transferred to the light sensor area to improve the ambient light sensor's field of view, thereby improving the timeliness and accuracy of screen brightness changes with ambient light. Simultaneously, the edges of the lens body are thinned, achieving overall device thinning without affecting the ambient light sensor's field of view. Alternatively, the refractive assembly can also be disposed on the display unit. Placing the concave lens array on the display unit not only improves the ambient light sensor's field of view but also simplifies the display module's structure, further reducing the overall device thickness.

[0035] Please see Figure 1 This is a schematic diagram of the hardware structure of a mobile terminal implementing various embodiments of this application. The mobile 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, etc. Those skilled in the art will understand that... Figure 1 The mobile terminal structure shown does not constitute a limitation on the mobile terminal. The mobile terminal may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0036] The following is combined Figure 1 A detailed introduction to each component of the mobile terminal:

[0037] The radio frequency unit 101 can be used for receiving and transmitting signals during information transmission or calls. Specifically, it receives downlink information from the base station and processes it with the processor 110; additionally, it transmits uplink data to the base station.

Although Figure 1 WiFi module 102 is shown, but it is understood that it is not a necessary component of a mobile terminal and can be omitted as needed without changing the nature of the invention.

[0039] The audio output unit 103 can convert audio data received by the radio frequency unit 101 or the WiFi module 102 or stored in the memory 109 into audio signals and output them as sound when the mobile terminal 100 is in call signal receiving mode, call mode, recording mode, voice recognition mode, broadcast receiving mode, etc. Furthermore, the audio output unit 103 can also provide audio output related to specific functions performed by the mobile terminal 100 (e.g., call signal receiving sound, message receiving sound, etc.).

[0040] 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 acquired by an image capture device (such as a camera) in video capture mode or image capture mode. The processed image frames can be displayed on the display unit 106. The image frames processed by the GPU 1041 can be stored in the memory 109 (or other storage media) or transmitted via the radio frequency unit 101 or the WiFi module 102. The microphone 1042 can receive sound (audio data) in operating modes such as telephone call mode, recording mode, and voice recognition mode, and can process such sound into audio data. The processed audio (voice) data can be converted into a format that can be transmitted to a mobile communication base station via the radio frequency unit 101 in telephone call mode. The microphone 1042 can 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.

[0041] The mobile terminal 100 also includes at least one sensor 105, such as a light sensor, a motion sensor, and other sensors.

Optionally, the ambient light sensor can adjust the brightness of the display panel 1061 according to the ambient light level, and the proximity sensor can turn off the display panel 1061 and / or backlight when the mobile terminal 100 is moved to the ear. As a type of motion sensor, the accelerometer sensor can detect the magnitude of acceleration in various directions (generally three axes), and can detect the magnitude and direction of gravity when stationary. It can be used for applications that recognize the phone's posture (such as landscape / portrait switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer, tapping), etc. Other sensors that may be configured in the phone, such as fingerprint sensors, pressure sensors, iris sensors, molecular sensors, gyroscopes, barometers, hygrometers, thermometers, and infrared sensors, will not be described in detail here.

[0042] The display unit 106 is used to display information input by the user or information provided to the user. The display unit 106 may include a display panel 1061, which may be configured in the form of a liquid crystal display (LCD), an organic light-emitting diode (OLED), or the like.

[0043] User input unit 107 can be used to receive input numerical or character information, and generate key signal inputs related to user settings and function control of the mobile terminal. Optionally, user input unit 107 may include touch panel 1071 and other input devices 1072. Touch panel 1071, also known as touch screen, can collect touch operations on or near the user (such as operations performed by the user using a finger, stylus, or any suitable object or accessory on or near touch panel 1071), and drive corresponding connection devices according to a pre-set program. 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 position and the signal generated by the touch operation, and transmits the signal to the touch controller; the touch controller receives touch information from the touch detection device, converts it into touch point coordinates, sends it to processor 110, and can receive and execute commands sent by processor 110. In addition, 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 also include other input devices 1072. Optionally, other input devices 1072 may include, but are not limited to, one or more of the following: physical keyboard, function keys (such as volume control buttons, power buttons, etc.), trackball, mouse, joystick, etc., without being specifically limited here.

[0044] Optionally, the touch panel 1071 may cover the 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. Subsequently, the processor 110 provides corresponding visual output on the display panel 1061 based on the type of touch event. Although in Figure 1 In this embodiment, the touch panel 1071 and the display panel 1061 are two independent components to realize the input and output functions of the mobile terminal. However, in some embodiments, the touch panel 1071 and the display panel 1061 can be integrated to realize the input and output functions of the mobile terminal. The specific implementation is not limited here.

[0045] Interface unit 108 serves as an interface through which at least one external device can connect to mobile terminal 100. For example, the external device may include a wired or wireless headset port, an external power supply (or battery charger) port, a wired or wireless data port, a memory card port, a port for connecting a device with an identification module, an audio input / output (I / O) port, a video I / O port, a headphone port, and so on. Interface unit 108 may be used to receive input (e.g., data, power, etc.) from the external device and transmit the received input to one or more elements within mobile terminal 100, or it may be used to transmit data between mobile terminal 100 and the external device.

[0046] The memory 109 can be used to store software programs and various data. The memory 109 may primarily include a program storage area and a data storage area. Optionally, the program storage area may store the operating system, applications required for at least one function (such as sound playback, image playback, etc.), etc.; the data storage area may store data created based on the use of the mobile phone (such as audio data, phonebook, etc.). Furthermore, the memory 109 may include high-speed random access memory, and may also include non-volatile memory, such as at least one disk storage device, flash memory device, or other volatile solid-state storage device.

[0047] The processor 110 is the control center of the mobile terminal. It connects various parts of the mobile terminal via various interfaces and lines. By running or executing software programs and / or modules stored in the memory 109, and by calling data stored in the memory 109, it performs various functions and processes data of the mobile terminal, thereby providing overall monitoring of the mobile terminal. The processor 110 may include one or more processing units; preferably, the processor 110 may integrate an application processor and a modem processor. Optionally, the application processor mainly handles the operating system, user interface, and applications, while the modem processor mainly handles wireless communication. It is understood that the modem processor may not be integrated into the processor 110.

[0048] The mobile terminal 100 may also include a power supply 111 (such as a battery) that supplies power to various components. Preferably, the power supply 111 can be logically connected to the processor 110 through a power management system, thereby enabling functions such as charging, discharging, and power consumption management through the power management system.

[0049] although Figure 1 As not shown, the mobile terminal 100 may also include a Bluetooth module, etc., which will not be described in detail here.

[0050] To facilitate understanding of the embodiments of this application, the communication network system on which the mobile terminal of this application is based is described below.

[0051] Please see Figure 2 , Figure 2 This application provides a communication network system architecture diagram. The communication network system is an LTE system based on the universal mobile communication technology. The LTE system includes a UE (User Equipment) 201, an E-UTRAN (Evolved UMTS Terrestrial Radio Access Network) 202, an EPC (Evolved Packet Core) 203, and the operator's IP services 204, which are connected in sequence.

[0052] Optionally, UE201 can be the aforementioned terminal 100, which will not be described in detail here.

[0053] E-UTRAN202 includes eNodeB2021 and other eNodeB2022s. Optionally, eNodeB2021 can connect to other eNodeB2022s via backhaul (e.g., X2 interface). eNodeB2021 connects to EPC203 and can provide UE201 with access to EPC203.

[0054] EPC203 may include an MME (Mobility Management Entity) 2031, an HSS (Home Subscriber Server) 2032, other MMEs 2033, an SGW (Serving Gateway) 2034, a PGW (Packet Data Network Gateway) 2035, and a PCRF (Policy and Charging Rules Function) 2036, etc. Optionally, MME2031 is the control node that handles signaling between UE201 and EPC203, providing bearer and connection management. HSS2032 is used to provide registers to manage functions such as the Home Location Register (not shown in the figure) and stores user-specific information such as service characteristics and data rates. All user data can be sent through SGW2034. PGW2035 can provide UE 201 IP address allocation and other functions. PCRF2036 is the policy and charging control decision point for service data flow and IP bearer resources. It selects and provides available policy and charging control decisions for the policy and charging enforcement function unit (not shown in the figure).

[0055] IP services 204 may include the Internet, intranet, IMS (IP Multimedia Subsystem), or other IP services.

[0056] Although the above description uses 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 also to other wireless communication systems, such as GSM, CDMA2000, WCDMA, TD-SCDMA, 5G and future new network systems (such as 6G), etc., without limitation.

[0057] Based on the above-described mobile terminal hardware structure and communication network system, various embodiments of this application are proposed.

[0058] First Embodiment

[0059] like Figure 3 and Figure 5 As shown, one embodiment of this application provides a display module, including a display unit 3, a control unit 4 electrically connected to the display unit 3, a light sensor 1 disposed on the back of the display unit 3 and electrically connected to the control unit 4, and a refractive assembly disposed between the display unit 3 and the light sensor 1. The display unit 1 has a light-transmitting hole 30. The light sensor 1 is used to receive light passing through the light-transmitting hole 30 and generate a corresponding sensing signal. The control unit 4 is used to adjust the brightness of the display unit 3 according to the sensing signal. The refractive assembly is used to refract the light passing through the light-transmitting hole 30 towards the center of the display unit 3 to increase the amount of light received by the light sensor 1. The control unit 4 can be connected to the processor of the aforementioned smart terminal, or can be directly used as part of the processor. The display device provided in this embodiment can serve as the display unit 106 of the aforementioned smart terminal.

[0060] A refractive assembly is positioned between the display unit 3 and the light sensor 1, including a lens body 2. A concave lens array 20 is formed on the lens body 2, and the surface of the lens body 2 facing the display unit is flat. The concave lens array 20 is positioned on the other side of the lens body 2 facing the light sensor 1, covering the entire area of ​​the light sensor 1. When external light passes through the display unit 3 and enters the lens body 2, it undergoes a first refraction due to the difference in refractive index of the lenses, with the refraction angle deflected towards the center. When the light exits from the back of the lens body 2, the interface becomes curved due to the concave lens array 20 on the back, causing the light to refract again, further deflecting the refraction angle towards the center. This diverts large-angle light rays towards the center, thereby improving the ambient light sensor's field of view. Furthermore, the lens body can be made of materials such as glass or PMMA with a transmittance >90% and a refractive index >1.

[0061] like Figure 4 As shown, in a further embodiment, the lens body 2 includes a first lens 21 and a second lens 22. The second lens 22 is disposed between the light sensor 1 and the first lens 21, and a concave lens array 20 is uniformly arranged on the side of the second lens 22 closest to the light sensor 1. When light passes through the display unit 3 and enters the first lens 21, it undergoes a first refraction, with the refraction angle deflecting towards the center. The first lens 21 and the second lens 22 are made of the same material and do not refract. When the light exits from the back of the second lens 22, it undergoes another refraction, with the refraction angle further deflecting towards the center, thereby increasing the ambient light sensor's field of view. By locally thickening the lens body 2, extending the first lens 21 into the area of ​​the light-transmitting aperture 30, the light path inside the refractive assembly is increased, achieving a larger ambient light sensor field of view.

[0062] The display unit 3 includes a panel layer 33, a flexible under-display support film 34, a foldable screen support layer 35, and an adhesive layer 36. The panel layer 33 is used to display images and is electrically connected to the light sensor 1. The control unit 4 is disposed within the panel layer 33. A black matrix 331 is provided in the panel layer 33. In order to allow light to pass through the black matrix 331 into the lens body 2 and the light sensor 1, multiple light-transmitting holes 30 are formed on the black matrix 331 and pass through the black matrix 331. The flexible under-display support film 34 is attached to the surface of the panel layer 33 facing the lens body 2. The other side of the flexible under-display support film 34 is the adhesive layer 36, which is connected to the lens body 2 of the refractive assembly through the adhesive layer 36. Further, the adhesive layer 36 may include materials such as foam, optically transparent adhesive, and PI double-sided adhesive.

[0063] The display unit 3 also includes an adhesive layer 37, which is used to bond the lens body 2 to the folding screen support layer 35. The adhesive layer 37 has at least one vent hole, which connects the space between the panel layer 33 and the refractive assembly to the outside environment, preventing pressure differences that could cause marks on the screen surface. The black matrix 331, folding screen support layer 35, adhesive layer 36, and adhesive layer 37 are all opaque layers. The light-transmitting hole 30 penetrates all three layers, allowing light to reach the lens body 2 of the refractive assembly and refract. However, the diameter of the light-transmitting hole 30 in the folding screen support layer 35, adhesive layer 36, and adhesive layer 37 is larger than that in the black matrix 33.

[0064] The display unit 3 also includes an optically transparent film 32 and a cover plate 31. The optically transparent film 32 is attached to the other side surface of the panel layer 33, and the cover plate 31 is attached to the optically transparent film 32. The cover plate 31 may include materials such as PET, glass cover, CPI, and ultra-thin flexible glass, and may be a single-layer or multi-layer composite structure.

[0065] Second Embodiment

[0066] One embodiment of this application provides a display module, including a display unit 3, a control unit 4 electrically connected to the display unit, a light sensor 1 disposed on the back of the display unit 3 and electrically connected to the control unit 4, and a refractive assembly disposed between the display unit 3 and the light sensor 1. The display unit 1 has a light-transmitting hole 30. The light sensor 1 is used to receive light passing through the light-transmitting hole 30 and generate a corresponding sensing signal. The control unit 4 is used to adjust the brightness of the display unit 3 according to the sensing signal. The refractive assembly is used to refract the light passing through the light-transmitting hole 30 towards the center of the display unit 3 to increase the amount of light received by the light sensor 1. The control unit 4 can be connected to the processor of the aforementioned smart terminal, or can be directly used as part of the processor. The display device provided in this embodiment can serve as the display unit 106 of the aforementioned smart terminal.

[0067] A refractive assembly is disposed between the display unit 3 and the light sensor 1, and includes a lens body 2. The lens body 2 includes a lens portion and a connecting portion. The lens portion forms a concave lens array 20, and the connecting portion is formed around the lens portion and is also bonded to the adhesive layer 36 of the display unit 3. The lens body 2 is thinned at the edges, making the thickness of the connecting portion smaller than the thickness of the lens portion, thereby achieving overall thinning without affecting the field of view of the ambient light sensor.

[0068] The other structures are the same as in the first embodiment, and will not be described again here.

[0069] Third Embodiment

[0070] One embodiment of this application provides a display module, including a display unit 3, a control unit 4 electrically connected to the display unit, a light sensor 1 disposed on the back of the display unit 3 and electrically connected to the control unit 4, and a refractive assembly disposed between the display unit 3 and the light sensor 1. The display unit 1 has a light-transmitting hole 30. The light sensor 1 is used to receive light passing through the light-transmitting hole 30 and generate a corresponding sensing signal. The control unit 4 is used to adjust the brightness of the display unit 3 according to the sensing signal. The refractive assembly is used to refract the light passing through the light-transmitting hole 30 towards the center of the display unit 3 to increase the amount of light received by the light sensor 1. The control unit 4 can be connected to the processor of the aforementioned smart terminal, or can be directly used as part of the processor. The display device provided in this embodiment can serve as the display unit 106 of the aforementioned smart terminal.

[0071] like Figure 6As shown, the display unit 3 includes a flexible under-display support film 34, an adhesive layer 35, and a foldable screen support layer 36. The flexible under-display support film 34 is attached to one side of the panel layer 33. One side of the adhesive layer 35D is bonded to the flexible under-display support film 34, and the other side of the adhesive layer 35D is bonded to the foldable screen support layer 36. Both the adhesive layer 35 and the foldable screen support layer 36 are transparent, and the light-transmitting hole 30 does not penetrate either the adhesive layer 35 or the foldable screen support layer 36. The refractive component is a concave lens array 20, which is disposed on one side of the foldable screen support layer 36 and covers the entire area of ​​the light sensor 1. Further, the flexible under-display support film 34 may include materials such as optically transparent adhesive, transparent PI double-sided adhesive, or transparent PET double-sided adhesive. The foldable screen support layer 36 may include materials such as glass or PMMA.

[0072] When external light passes through the interior of display unit 3, it is not refracted. However, when light exits from the back of the foldable screen support layer 36, the interface becomes curved due to the concave lens array 20 on the back, causing the light to refract. The refraction angle deflects towards the center, diverting large-angle light rays to the center, thereby improving the field of view of the ambient light sensor. Simultaneously, placing the refractive component on display unit 3 simplifies the structure of the display module and further reduces the overall thickness of the device.

[0073] The other structures of the display unit 3 are the same as those in the first embodiment, and will not be described again here.

[0074] In summary, this application provides a display module including a display unit 3, a light sensor 1, and a refractive assembly. The refractive assembly is disposed between the display unit 3 and the light sensor 1. The refractive assembly includes a lens body 2, and a concave lens array 20 is provided on the lens body 20. By setting the refractive assembly, light is refracted and deflected towards the center, transferring large-angle light to the area of ​​the light sensor 1, thereby improving the ambient light sensor field of view of the light sensor 1, and thus improving the timeliness and accuracy of the screen brightness changing with ambient light. At the same time, while keeping the thickness of the lens body 2 unchanged, the connecting part of the lens body 2 can be thinned, achieving overall thickness reduction without affecting the ambient light sensor field of view of the light sensor 1. Alternatively, the refractive assembly can also be disposed on the display unit 3. In this case, the refractive assembly is a concave lens array 20. Disposing of the concave lens array 20 on the display unit 3 not only improves the ambient light sensor field of view of the light sensor 1, but also simplifies the structure of the display module, further reducing the overall thickness.

[0075] like Figure 7As shown, embodiments of this application also provide a smart terminal, including a display module as described in any of the above embodiments. The smart terminal provided in this embodiment can function as the aforementioned smart terminal 100. The smart terminal is preferably a portable smartphone, and the display module is preferably a foldable screen 5. The foldable screen 5 includes a bending area 51 and a non-bending area 52. A light-sensing hole 50 is provided at one end of the non-bending area 51. Light enters the display unit 3 and the light sensor 1 through the light-sensing hole 50. The light sensor 1 then transmits information to the control unit 4 to control the screen brightness. In a further embodiment, the number of light-sensing holes 50 is set to at least two, and at least two light-sensing holes 50 are symmetrically arranged on both sides of the bending area 51. This design not only enables more optimized performance but also further improves the timeliness and accuracy of screen brightness changes with ambient light, enhancing the user experience of the smart device.

[0076] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
