Description

Technical Field

[0001] The embodiments of the present invention relate to, but are not limited to, the field of terminal technology, and particularly to an under-display camera display device, a terminal device, a control method for the under-display camera device, a controller, and a computer-readable storage medium. Background Technology

[0002] With the increasing application scenarios of front-facing cameras and the growing popularity of full-screen devices, how to design front-facing camera modules to achieve a higher screen-to-body ratio has become a crucial issue in terminal technology development. Some existing devices use waterdrop or punch-hole displays to house the camera module, while others utilize mechanical structures to hide the camera module inside the phone and slide it out when needed. However, there is still room for improvement in screen-to-body ratio with waterdrop and punch-hole displays, and repeated adjustments to the mechanical mechanisms can easily damage the device. Furthermore, some devices place the camera module at the bottom of the full-screen area. However, because camera modules require high light transmittance, this method not only significantly reduces the pixel count of the screen display module in the area corresponding to the camera module, affecting the display quality in that area, but also results in low light transmittance in the area around the camera module, impacting the camera's shooting performance and ultimately significantly affecting the user experience. Summary of the Invention

[0003] The following is an overview of the subject matter described in detail herein. This overview is not intended to limit the scope of the claims.

[0004] This invention proposes an under-display camera display device, a terminal device, a control method for the under-display camera device, a controller, and a computer-readable storage medium, which can improve the shooting effect and screen display effect of the under-display camera terminal device, thereby increasing the screen ratio of the full-screen terminal and optimizing the user experience.

[0005] In a first aspect, embodiments of the present invention provide an under-display camera display device, comprising: a first display module including a light-transmitting layer and a display layer, the light-transmitting layer being located on one side of the display layer, the display layer having a notch, and the light-transmitting layer having a transmissive display area corresponding to the notch; a second display module being located on the other side of the display layer and offset from the notch; a camera module being located on the other side of the display layer; and an optical component being located between the camera module and the first display module, the second display module facing the optical component, the optical component being used to reflect the display information of the second display module to the transmissive display area, and the optical component being further used to transmit light passing through the transmissive display area to the camera module.

[0006] Secondly, embodiments of the present invention also provide a terminal device, the terminal device including the under-display camera display device as described in the first aspect embodiment above.

[0007] Thirdly, embodiments of the present invention also provide a control method for an under-display camera display device, applied to a controller of the under-display camera display device. The under-display camera display device further includes a first display module, a second display module, a camera module, and an optical component. The first display module includes a light-transmitting layer and a display layer. The light-transmitting layer is located on one side of the display layer, and the display layer has a notch. The light-transmitting layer has a transmissive display area corresponding to the notch. The second display module is located on the other side of the display layer and is offset from the notch. The camera module is located on the other side of the display layer. The optical component is located between the camera module and the first display module, and the second display module faces the optical component.

[0008] The control method includes:

[0009] Obtain the working status of the camera module;

[0010] When the working state is off, upon receiving drive commands for the first display module and the second display module, the first display module is controlled to operate, and the second display module is controlled to operate so that the optical component reflects the display information of the second display module to the transmissive display area.

[0011] Fourthly, embodiments of the present invention also provide a controller, the controller comprising: a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to perform the control method for the under-display camera display device as described in the third aspect above.

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0027] It should be noted that although functional modules are divided in the device schematic diagram and a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the device or the order in the flowchart. The terms "first," "second," etc., in the specification, claims, or the aforementioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0028] With the widespread adoption of 5G smartphones as fashionable and fast-moving consumer electronics, and the popularity of applications like short videos and WeChat video calls, the use of front-facing cameras is becoming increasingly common. Currently, for aesthetic reasons, how to design the front-facing camera module to achieve a higher screen-to-body ratio in full-screen devices has become a crucial issue in terminal technology development. However, in reality, achieving a high screen-to-body ratio requires careful consideration of the front-facing camera's layout. Some existing devices use waterdrop notches or punch-hole displays to house the camera module, while others utilize mechanical structures to hide the camera module inside the phone and slide it out when needed. However, there is still room for improvement in the screen-to-body ratio with waterdrop and punch-hole displays, and repeated adjustments to the mechanical mechanisms can easily damage the device. Furthermore, some devices employ under-display camera technology, placing the camera module in the lower area of ​​the full-screen display to address the screen-to-body ratio and front-facing camera layout issues. However, because the screen area corresponding to the camera module has high light transmittance requirements, the pixel count of the display module must be significantly reduced, severely impacting the screen display in that area. Simultaneously, the lower light transmittance of the screen area corresponding to the camera module also affects the camera's shooting performance. In summary, the technical solutions for improving screen ratio still have shortcomings. Among them, the under-display camera solution suffers from poor shooting and display effects, which affects the user's experience of using a full-screen display.

[0029] Based on the above, embodiments of the present invention provide an under-display camera display device, a terminal device, a control method for the under-display camera device, a controller, and a computer-readable storage medium, which can improve the shooting effect and screen display effect of the under-display camera terminal device, thereby increasing the screen ratio of the full-screen terminal and optimizing the user experience.

[0030] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0031] In a first aspect, embodiments of the present invention provide an under-display camera display device.

[0032] Reference Figure 1 and Figure 2An embodiment of the present invention provides an under-display camera display device, which includes: a first display module 100, a second display module 200, a camera module 300, and an optical component 400. The first display module 100 includes a light-transmitting layer 110 and a display layer 120. The light-transmitting layer 110 is located on one side of the display layer 120. The display layer 120 has a notch 121, and the light-transmitting layer 110 has a transmissive display area 111 corresponding to the position of the notch 121. The second display module 400... Group 200 is located on the other side of display layer 120 and is offset from notch 121; camera module 300 is located on the other side of display layer 120; optical component 400 is located between camera module 300 and first display module 100, second display module 200 faces optical component 400, optical component 400 is used to reflect the display information of second display module 200 to transmissive display area 111, and optical component 400 is also used to transmit light passing through transmissive display area 111 to camera module 300.

[0033] When using this under-screen camera display device, when the camera module 300 is in the open state, the optical component 400 transmits light through the transmission display area 111 to the camera module 300; when the camera module 300 is in the closed state, and the first display module 100 and the second display module 200 are in the working state, the optical component 400 reflects the display information of the second display module 200 to the transmission display area 111.

[0034] For example, such as Figure 5 As shown, Figure 5 This is a schematic diagram illustrating the reflection principle of an under-display camera display device according to another embodiment of the present invention. When the transparent display area above the camera module 300 needs to display four circular patterns, the two circular patterns displayed by the first reflective display module 210 on the left are reflected by the first reflective surface 410 on the left side of the optical component 400. Similarly, the other two circular patterns displayed by the second reflective module on the right are reflected by the second reflective surface 420 on the right side of the optical component 400. At this time, when viewed from the front, all four circular patterns can be displayed directly above the camera module 300.

[0035] It is understood that, according to the technical solution of the present invention, when applying under-display camera technology, the shooting effect of the camera module 300 and the display effect of the screen display module can be improved without reducing the display pixels or light transmittance of the screen display module, making the under-display camera solution more feasible, thereby increasing the screen ratio of the full-screen terminal and optimizing the user experience.

[0036] It is worth noting that the embodiments of the present invention greatly improve the shooting effect of the under-display camera module 300, while the screen display module does not need to utilize the gaps between crystals for light transmission, thus ensuring the display effect. This allows the embodiments of the present invention to simultaneously possess both excellent shooting performance and rich image display. Furthermore, the manufacturing process of the embodiments of the present invention is low-difficulty and highly reliable, and due to the low manufacturing cost, the added value of the technology is very high.

[0037] It should be noted that the transmissive display area 111 of the light-transmitting layer 110 corresponds to the notch 121 of the display layer 120, and the second display module 200 is offset from the notch 121 so that an optical path can be formed between the second display module 200, the optical component 400, and the transmissive display area 111, allowing the display information of the second display module 200 to be reflected to the transmissive display area 111 through the optical component 400. For example, there are two second display modules 200, located on either side of the notch 121, with the optical component 400 positioned between these two second display modules 200. It should be noted that the position of the second display module 200 is sufficient to allow an optical path to be formed between the second display module 200, the optical component 400, and the transmissive display area 111, so that the display information of the second display module 200 is reflected to the transmissive display area 111; this embodiment does not impose any limitations on this.

[0038] For example, the light-transmitting layer 110 is a glass cover. It is understood that glass has good transmission and display effects, and can resist certain external impacts, thus protecting the device.

[0039] Reference Figure 3 For example, the optical component 400 is a reflector, which is provided with a first reflective surface 410 and a second reflective surface 420. The second display module 200 includes a first reflective display module 210 and a second reflective display module 220. The first reflective display module 210 and the second reflective display module 220 are respectively located on both sides of the reflector. The transmission display area 111 includes a first sub-transmission display area 1111 and a second sub-transmission display area 1112. The first reflective surface 410 is used to reflect the display information of the first reflective display module 210 to the first sub-transmission display area 1111, and the second reflective surface 420 is used to reflect the display information of the second reflective display module 220 to the second sub-transmission display area 1112.

[0040] Specifically, when the camera module 300 is in the off state and the first display module 100 and the second display module 200 are in the working state, the reflector reflects the display information of the first reflective display module 210 to the first sub-transmission display area 1111 via the first reflective surface 410, and also reflects the display information of the second reflective display module 220 to the second sub-transmission display area 1112 via the second reflective surface 420.

[0041] It should be noted that the first reflective display module 210 and the second reflective display module 220 can be an integral structure or multiple display modules spliced ​​together to form a corresponding shape. This embodiment does not impose any restrictions on them.

[0042] For example, the optical component 400 is a double-reflecting lens, and the first display module 100 and the second display module 200 are located on both sides of the double-reflecting lens and are arranged symmetrically along the central axis of the double-reflecting lens.

[0043] Reference Figure 3 and Figure 5 For example, the angle between the first reflective surface 410 and the first reflective display module 210 is 45 degrees, and the angle between the second reflective surface 420 and the second reflective display module 220 is 45 degrees.

[0044] Specifically, a first reflective surface 410 and a second reflective surface 420 are respectively provided on both sides of the reflector. The first display module 100 and the second display module 200 are respectively located on both sides of the reflector, with the first display module 100 facing the first reflective surface 410 and the second display module 200 facing the second reflective surface 420. When the camera module 300 is in the off state and the first display module 100 and the second display module 200 are in the working state, the light emitted by the display information of the first display module 100 is directed toward the first reflective surface 410 and reflected from the first reflective surface 410 to the transmissive display area 111 of the display layer 120, forming the reflected light path of the first display module 100. Similarly, the light emitted by the display information of the second display module 200 is directed toward the second reflective surface 420 and reflected from the second reflective surface 420 to the transmissive display area 111 of the display layer 120, forming the reflected light path of the second display module 200.

[0045] Reference Figure 4 For example, the optical component 400 is provided with a groove 430 for placing the camera module 300.

[0046] Specifically, when the camera module 300 is in the open state, external light passes through the transmissive display area 111 of the light-transmitting layer 110 and is then transmitted to the camera module 300 by the optical component 400. Therefore, by providing the groove 430 for placing the camera module 300, external light can be easily transmitted from the optical component 400 to the camera module 300, making the structure more compact and reducing light loss during transmission, thereby improving the shooting effect of the camera module 300.

[0047] For example, one side of the optical component 400 is tightly fitted to the display layer 120, and the corresponding other side is provided with a groove 430 for placing the camera module 300. It should be noted that the groove 430 can be located in the center of the other side of the optical component 400, and this embodiment does not limit it. In addition, the groove 430 can be circular or the like, and this embodiment does not limit it.

[0048] Reference Figure 1 and Figure 2 For example, the under-screen camera display device also includes a positioning component 500 for positioning the second display module 200 and the optical component 400.

[0049] Specifically, after the positioning component 500 fixes the second display module 200, the optical component 400 is placed in the corresponding position of the second display module 200. Then, the side of the camera module 300 used to obtain external light is tightly attached to the optical component 400. After that, the other side of the camera module 300 is fixedly connected to the PCB board or the corresponding bracket.

[0050] For example, the positioning component 500 is a positioning border, and as... Figure 2 As shown, the positioning border has a semi-enclosed structure.

[0051] Reference Figure 1 and Figure 2 For example, the under-screen camera display device also includes a ribbon cable assembly 600, the positioning component 500 is provided with a through hole (not shown in the figure), the ribbon cable assembly 600 passes through the through hole, and the ribbon cable assembly 600 is electrically connected to the second display module 200.

[0052] Specifically, the ribbon cable assembly 600 passes through the through hole of the positioning assembly 500 and is electrically connected to the second display module 200, thereby enabling the second display module 200 to display the corresponding display information.

[0053] Based on the under-display camera display device of the above embodiments, various embodiments of the terminal device of the second aspect of the present invention are presented below.

[0054] One embodiment of the present invention provides a terminal device including the under-display camera display device of the various embodiments of the first aspect described above.

[0055] Specifically, the terminal device in this embodiment of the invention can be a mobile phone, tablet computer, communication payment terminal with facial recognition function, management terminal, computer, or other smart terminal device with a display screen.

[0056] It is understood that since the terminal device of the second aspect embodiment of the present invention and the under-display camera display device of any of the first aspects embodiment belong to the same inventive concept, the specific implementation method and technical effect of the terminal device of the second aspect embodiment of the present invention can be referred to the specific implementation method and technical effect of the under-display camera display device of any of the first aspects embodiment, and will not be repeated here.

[0057] Furthermore, based on the under-display camera display device of the first aspect embodiment described above, various embodiments of the control method of the under-display camera display device of the third aspect of the present invention are presented below.

[0058] like Figure 7 As shown, Figure 7 This is a schematic diagram of a system architecture platform 100 for performing a control method for an under-display camera display device according to an embodiment of the present invention.

[0059] exist Figure 7 In this example, the system architecture platform includes a processor 800 and a memory 700, which can be connected via a bus or other means. Figure 7 Taking the example of a connection between China and Israel via a bus.

[0060] Memory 700, as a non-transitory computer-readable storage medium, can be used to store non-transitory software programs and non-transitory computer-executable programs. Furthermore, memory 700 may include high-speed random access memory 700, and may also include non-transitory memory 700, such as at least one disk storage device 700, flash memory device, or other non-transitory solid-state memory 700. In some embodiments, memory 700 may optionally include memory 700 remotely located relative to processor 800, and these remote memories 700 can be connected to the system architecture platform via a network. Examples of such networks include, but are not limited to, the Internet, corporate intranets, local area networks, mobile communication networks, and combinations thereof.

[0061] Those skilled in the art will understand that this system architecture platform can be applied to 5G communication network systems and subsequent evolved mobile communication network systems, and this embodiment does not specifically limit it.

[0062] It will be understood by those skilled in the art that Figure 7 The system architecture platform shown does not constitute a limitation on the embodiments of the present invention, and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0063] exist Figure 7 In the system architecture platform shown, the processor 800 can call the control program stored in the memory 700 to execute the control method of the under-display camera display device.

[0064] Based on the above system architecture platform, various embodiments of the control method for the under-display camera display device of the present invention are proposed below.

[0065] Reference Figure 1 and Figure 2 For example, the control method of the under-display camera display device is applied to the controller of the under-display camera display device. The under-display camera display device also includes a first display module 100, a second display module 200, a camera module 300, and an optical component 400. The first display module 100 includes a light-transmitting layer 110 and a display layer 120. The light-transmitting layer 110 is located on one side of the display layer 120. The display layer 120 is provided with a notch 121. The light-transmitting layer 110 is provided with a transmissive display area 111 corresponding to the position of the notch 121. The second display module 200 is located on the other side of the display layer 120 and is offset from the position of the notch 121. The camera module 300 is located on the other side of the display layer 120. The optical component 400 is located between the camera module 300 and the first display module 100. The second display module 200 faces the optical component 400.

[0066] like Figure 8 As shown, the control method of the under-screen camera display device includes, but is not limited to, the following steps S100 and S200.

[0067] Step S100: Obtain the working status of the camera module 300;

[0068] It should be noted that the working status of the camera module 300 includes both on and off states.

[0069] Step S200: When the working state is off, when the driving commands of the first display module 100 and the second display module 200 are obtained, the first display module 100 is controlled to work, and the second display module 200 is controlled to work so that the optical component 400 reflects the display information of the second display module 200 to the transmission display area 111.

[0070] It should be noted that when the camera module 300 is in the off state and the first display module 100 and the second display module 200 are in the on state, the first display module 100 and the second display module 200 are controlled to display corresponding display information respectively. The display information of the second display module 200 will be reflected onto the transmission display area 111 of the light-transmitting layer 110 under the action of the optical component 400, so that the display information of the first display module 100 and the second display module 200 can be combined into complete display information on the light-transmitting layer 110.

[0071] Specifically, through steps S100 and S200, when the camera module 300 is in a closed state and the first display module 100 and the second display module 200 are in a working state, the optical component 400 reflects the display information of the second display module 200 to the transmissive display area 111. It is understood that, according to the technical solution of this embodiment of the invention, when applying under-display camera technology, the display effect of the screen display module can be improved without reducing the display pixels or light transmittance of the screen display module, making the under-display camera solution more feasible, thereby increasing the screen-to-body ratio of the full-screen terminal and optimizing the user experience.

[0072] Reference Figure 9 For example, the control method of the under-screen camera display device may further include, but is not limited to, the following steps S300.

[0073] Step S300: When the working state is on, turn off the second display module 200 so that the optical component 400 transmits the light passing through the transmission display area 111 to the camera module 300.

[0074] Specifically, when the camera module 300 is in the open state, the optical component 400 transmits light through the transmission display area 111 to the camera module 300. It can be understood that through steps S100 to S300, when applying under-display camera technology, the shooting effect of the camera module 300 and the display effect of the screen display module can be improved without reducing the display pixels or light transmittance of the screen display module, thereby increasing the screen-to-body ratio of the full-screen terminal.

[0075] Reference Figure 10 For example, the optical component 400 is a reflector, which is provided with a first reflective surface 410 and a second reflective surface 420. The second display module 200 includes a first reflective display module 210 and a second reflective display module 220, which are located on opposite sides of the reflector. The transmission display area 111 includes a first sub-transmission display area 1111 and a second sub-transmission display area 1112. Step S200 specifically includes, but is not limited to, steps S210 and S220.

[0076] Step S210: Control the first reflective display module 210 to work so that the first reflective surface 410 reflects the display information of the first reflective display module 210 to the first sub-transmissive display area 1111;

[0077] Step S220: Control the second reflective display module 220 to work so that the second reflective surface 420 reflects the display information of the second reflective display module 220 to the second subtransmissive display area 1112.

[0078] Specifically, when the camera module 300 is in the off state, upon receiving drive commands from the first display module 100 and the second display module 200, the first display module 100 is controlled to display the corresponding display information, and the first reflective display module 210 is controlled to operate so that the first reflective surface 410 reflects the display information of the first reflective display module 210 to the first sub-transmissive display area 1111. The second reflective display module 220 is controlled to operate so that the second reflective surface 420 reflects the display information of the second reflective display module 220 to the second sub-transmissive display area 1112, so that the light-transmitting layer 110 displays complete display information.

[0079] For example, step S200 may also include, but is not limited to, the following steps S410 and S420.

[0080] Step S410: Obtain the information to be displayed and perform a preset operation on the information to be displayed;

[0081] Step S420: Display the information to be displayed after performing the preset operation on the first reflective display module 210 and the second reflective display module 220.

[0082] It should be noted that the information to be displayed may include patterns, text, etc., and this embodiment does not limit it.

[0083] It should be noted that the preset operation includes: converting the information to be displayed into a pixel matrix, and dividing the pixel matrix into a first pixel matrix area, a second pixel matrix area, and a third pixel matrix area. The first pixel matrix area and the third pixel matrix area are symmetrical about the central axis of the second pixel matrix area, and the second pixel matrix area corresponds to the display information of the transmissive display area 111.

[0084] For example, step S420 may also include, but is not limited to, the following steps S421 and S422.

[0085] Step S421: Display the first pixel information group of the first dot matrix area and the second pixel information group of the third dot matrix area on the first display module 100;

[0086] Step S422: Mirror and invert the second pixel information group on the second dot matrix area, and display the inverted second pixel information group on the second display module 200.

[0087] Specifically, such as Figure 6As shown, when the camera module 300 is in the off state, it receives drive commands from the first display module 100 and the second display module 200. The controller divides the information to be displayed into three parts. Taking a row of pixels as an example, where n>m, it can be divided into: (a1, ak), (ak, a(k+m / 2)), (a(k+m / 2), am), (am, an). Among them, (ak, a(k+m / 2)) is assigned to the first reflective display module 210 and mirrored and inverted (a(k+m / 2), ak). Similarly, (a(k+m / 2), am) is assigned to the second reflective display module 220 and mirrored and inverted (am, a(k+m / 2)). Thus, after mirror reflection, the pixel row of the information displayed on the light-transmitting layer 110 is still: (a1, ak), (ak, a(k+m / 2)), (a(k+m / 2), am), (am, an), that is: (a1, an) complete row information. When the camera module 300 is in the on state, the controller turns off the second display module 200 so that the optical component 400 transmits light through the transmission display area 111 to the camera module 300.
