Description

Technical Field

[0001] Embodiments of the present invention relate to the field of intelligent terminals, and more specifically, to a method and apparatus for controlling a camera and an under-display camera structure.

Background Art

[0002] Full screen literally means that the entire front of the mobile phone is a screen, using a design without frames at the four frame positions of the mobile phone, aiming for a screen ratio close to 100%. However, in reality, limited by current technology, currently it is only a mobile phone with an ultra-high screen ratio, and there is no mobile phone that can achieve a 100% front screen ratio. Currently, the so-called full-screen mobile phones refer to mobile phones that can reach a screen ratio of 90% or more and have an ultra-narrow bezel design.

[0003] All full-screen mobile phone manufacturers must place earphones, front cameras, and various sensors, which are common user demands in daily life, on the front of the mobile phone. However, when these devices are placed on the front of the mobile phone, they inevitably occupy a part of the display area, and they must face and solve this common problem. Currently, various major mobile phone manufacturers are trying to reduce the area occupied by these functional devices in one way or another, so they have successively launched their own full-screen mobile phones, and various full-screen solutions such as "notch screens", "Infinity U", and "punched screens" have emerged.

[0004] In related technologies, an under-display camera has been proposed, which includes a display panel, a backlight module, a light guide member, and a light source member. The backlight module is installed on one side of the display panel, and a first opening is provided at a position corresponding to the under-display camera. The light guide member is inserted into the first opening and is used to guide the light beam incident on the light guide member to the display panel area corresponding to the first opening. The light source member is used to provide a light source for the light guide member.

[0005] When the under-display camera is activated, the light source member is turned off. When the under-display camera is not activated, the light source member can be turned on or off, so that the through hole or blind hole on the display panel can be made visible again, and the image quality continuously obtained by the under-display camera can be maintained.

[0006] By providing a light source to the side light guide member, the direction of light cannot be adjusted or clustered, and most of the light cannot be incident upward on the glass region, which affects the efficiency of the backlight. Also, when using the front camera, correction light cannot be provided.

[0007] In the related art, there is a problem that the shooting effect is low when the ambient light is weak due to the limited incident light of the under-display camera.

[0030] Hereinafter, the present invention will be described in detail based on embodiments with reference to the drawings.

[0037] In this embodiment, a method for controlling an under-display camera executed on the mobile terminal or the network architecture is provided. FIG. 2 is a flowchart of the method for controlling an under-display camera according to an embodiment of the present invention. As shown in FIG. 2, the flow includes the following steps.

[0038] Step S202, when it is detected that the camera is in the on state, turn off the first type of lamp beads approaching the camera end determined in advance, control the second type of lamp beads moving away from the camera to the lit state, and after the light from the second type of lamp beads is refracted by the convex glass to form a light ring on the convex glass, make the convex glass in a non-display state of the screen. A display is installed above the camera. The display includes the display glass and the display area backlight. An opening area is installed in the display area backlight above the camera. The display glass forms a convex glass with a convex shape in the direction of the camera in the opening area. A flexible circuit board presenting an annular conical structure is connected between the convex glass and the camera so as to surround the viewing angle of the camera. A plurality of lamp beads are sequentially arranged on the flexible circuit board from the camera end to the convex glass end.

[0039] In an exemplary embodiment, the above step S202 specifically includes the step of turning off the first type of lamp beads approaching the camera end determined in advance and controlling the second type of lamp beads moving away from the camera to the lit state.

[0040] Step S204, when it is detected that the camera is in the off state, control all of the plurality of lamp beads to the lit state, and provide backlight to the convex glass after being refracted by the convex glass, so as to make the convex glass in a screen display state.

[0041] In an exemplary embodiment, specifically, in step S204, the brightness of the plurality of lamp beads is controlled by a backlight chip, and the flexible circuit board is used to conduct the plurality of lamp beads and is connected to the backlight chip.

[0042] By steps S202 to S208 above, a convex glass is installed below the display glass, and a plurality of lamp beads are installed below the convex glass, so as to realize the installation below the display glass of the camera. When the camera is turned off, the convex glass is a normal display glass. When the camera is turned on, the displays of some lamp beads and the convex glass are turned off, and the light from the lamp beads away from the camera is refracted by the convex glass to form a light ring on the convex glass, so as to project auxiliary light onto the camera, thereby solving the problem in the related art that the incident light of the under-display camera is limited and the shooting effect is low when the ambient light is weak, and improving the shooting effect when the ambient light is weak.

[0043] In an exemplary embodiment, after controlling the second type of lamp beads away from the camera, which are determined in advance, to be in a lit state, the second type of lamp beads are adjusted to the maximum brightness value.

[0044] In an exemplary embodiment, before turning off the first type of lamp beads close to the camera end, which are determined in advance, and controlling the second type of lamp beads away from the camera, which are determined in advance, to be in a lit state, the inclination angle of the annular conical structure is determined. Further, the light incident angle of the camera, the pixels of the camera, the brightness of the display, the thickness of the backlight of the display area, and the size of the opening area are obtained, and the inclination angle of the annular conical structure is determined according to the light incident angle of the camera, the pixels of the camera, the brightness of the display, the thickness of the backlight of the display area, and the size of the opening area.

[0045] Determine the angle of the light after the light emitted from the lamp bead is reflected by the convex glass according to the tilt angle of the annular conical structure, the radian of the convex glass, and the emission angle of the lamp bead, and determine the first type of lamp bead and the second type of lamp bead according to the angle of the light, the emission angle of the lamp bead, and the light incident angle of the camera.

[0046] In other exemplary embodiments, after determining the tilt angle of the annular conical structure, determine the number of the plurality of lamp beads and the arrangement method of the plurality of lamp beads according to the luminance of the display, the tilt angle of the annular conical structure, and the size of the opening region.

[0047] From the description of the above embodiments, those skilled in the art can realize according to the methods of the above embodiments by borrowing the form of software and the necessary general-purpose hardware platform. Of course, it can be realized through hardware, but in many cases, it can be clearly understood that the former is a more preferable embodiment.

[0048] Based on such understanding, the essence of the technical solution of the present invention or the part contributing to the prior art can be embodied in the form of a software product. The computer software product is stored in a storage medium (for example, ROM / RAM, magnetic disk, optical disk), and includes a plurality of instructions for causing a terminal device (which may be a mobile phone, a server, or a network device, etc.) to execute the methods described in each embodiment of the present invention.

[0049] In this embodiment, an under-display camera structure is further provided. FIG. 3 is a schematic diagram of the under-display camera structure according to the embodiment of the present application. As shown in FIG. 3, it includes a display 1 and a camera 2 installed under the display. The display 1 includes a display glass 11 and a display area backlight 12. An opening area is installed in the display area backlight above the camera 2. The display glass 11 forms a convex glass 13 by presenting a convex shape in the direction of the camera 2 in the opening area. A flexible circuit board 3 presenting an annular conical structure is connected between the convex glass 13 and the camera 22 so as to surround the viewing angle of the camera 2. A plurality of lamp beads are sequentially arranged on the flexible circuit board 3 from the end of the camera 2 to the end of the convex glass. When the camera 2 is in the on state, the lamp bead among the plurality of lamp beads approaching the end of the camera 2 is in the off state, and the lamp bead away from the camera 2 is in the lit state. The light from the lamp bead away from the camera 2 is refracted by the convex glass 13 to form a light ring on the convex glass 13, thereby making the convex glass 13 in a non-display state of the screen.

[0050] When the camera 2 is in the off state, all the plurality of lamp beads are in the lit state, and by providing backlight to the convex glass 13 after being refracted by the convex glass 13, the convex glass 13 is made in a display state of the screen.

[0051] In an exemplary embodiment, the lamp bead away from the camera 2 is at the maximum luminance value.

[0052] In an exemplary embodiment, the angle of the annular conical structure of the flexible circuit board 3 is determined by the viewing angle of the camera 2, the pixels of the camera 2, the luminance of the display, the thickness of the display area backlight, and the size of the opening area.

[0053] In another exemplary embodiment, the flexible circuit board 3 is used to conduct the plurality of lamp beads and is connected to the backlight chip, and the backlight chip is used to control the brightness of the plurality of lamp beads.

[0054] In this embodiment, the display glass 11 is divided into a flat glass 12 in the normal display area and a convex glass 13 in the front camera area. The light incident angle of the front camera 2 is the viewing angle 301. Since the backlight 12 in the normal display area can use the conventional backlight structure solution, it will not be described in detail. The backlight 4 in the front camera area is divided into a plurality of small LED lamp beads and a flexible circuit board 3. The flexible circuit board 3 connects and conducts the plurality of LED lamp beads, and the brightness of each lamp bead is independently controlled by the backlight chip. The backlight 4 in the front camera area generally presents an annular conical structure, and the central opening avoids the viewing angle of the front camera 2.

[0055] FIG. 4 is a schematic diagram of an under-display camera structure according to a preferred embodiment of the present application. As shown in FIG. 4, when it is necessary to display the entire screen without using a front camera, the LED lamp beads emit light to provide backlight for the display glass in the front camera area. Each LED lamp bead has a certain irradiation angle, which can completely cover the entire display glass in the front camera area. By adjusting the brightness of each LED lamp bead by the backlight chip, the backlight of the entire display glass in the front camera area can be made uniform without adding a light diffusing material or a light guiding material individually. The light from the LED lamp beads passes through the converging action of the convex glass 13 in the front camera area, converges upward and emits from the screen to achieve a better display effect.

[0056] FIG. 5 is a second schematic diagram of an under-display camera structure according to a preferred embodiment of the present application. As shown in FIG. 5, when it is necessary to use the front camera, if all of the LED lamp beads are still lit, a part of the light from the LED lamp beads approaching the front camera enters the viewing angle of the front camera through the reflection of the convex glass 13, interfering with the imaging of the front camera.

[0057] FIG. 6 is a third schematic diagram of an under-display camera structure according to a preferred embodiment of the present application. As shown in FIG. 6, when using the front camera, in order to prevent the light from the LED lamp beads from entering the viewing angle of the front camera by reflection, only a part of the LED lamp beads away from the front camera are turned on, and the brightness of the turned-on LED lamp beads is maximized. At this time, the convex glass 13 does not display the screen and forms a light ring. Most of the images captured by the front camera are of nearby people and scenery. The light emitted from the light ring irradiates and reflects on the nearby people and scenery, increasing the light incident amount of the front camera 2 and improving the imaging effect.

[0058] FIG. 7 is a fourth schematic diagram of an under-display camera structure according to a preferred embodiment of the present application. As shown in FIG. 7, when turning on the front camera, it is necessary to determine which LED lamp beads can be lit by a method combining 3D simulation calculation and dark box debugging. The main factors include the tilt angle a of the flexible circuit board, the radian b of the convex glass, the emission angle c of the LED lamp beads, the light incident angle d of the front camera, the angle e of the light after being reflected by the convex glass from the lamp beads, the lateral distance f from the end of the backlight opening to the center of the front camera, and the lateral distance h from the lamp beads to the center of the front camera.

[0059] When performing 3D simulation calculations, the two most important factors are the angle e of the light reflected by the convex glass from the light emitted by the lamp bead and the lateral distance h from the lamp bead to the center of the front camera. The smaller the angle e of the light, the more difficult it is for the light to enter the front camera. The larger the lateral distance h from the lamp bead to the center of the front camera, the more difficult it is for the light to enter the front camera.

[0060] Based on the relationship between each dimension shown in Fig. 7, it can be calculated that e = 90° - a + (c / 2) - 2b and h = f - g * sin(a). According to the calculation formula, to a certain extent, the larger the angles a and b are, the smaller the angle e is. The smaller the angle c is, the smaller the angle e is. To a certain extent, the larger the distance f is, the larger the distance h is. The smaller the distance g and the angle a are, the larger the distance h is. When specifically designing each dimension and angle, comprehensive consideration should be taken to avoid problems such as the blocking of the flexible circuit board for the field of view angle of the front camera and the exposure of the front camera end due to an overly large backlight opening.

[0061] In actual application, first perform 3D simulation calculations to obtain an initial LED lamp bead design plan. To finally confirm which LED lamp beads can be turned on when using the front camera, detailed debugging needs to be carried out in a dark box. Put the entire machine into the dark box, turn on some of the lamp beads that can be lit obtained from the 3D simulation calculation, and at the same time turn on the front camera. When the light sensor of the front camera can sense light, it is necessary to turn off a row of lamp beads approaching the front camera until the light sensor of the front camera can no longer sense the light reflected from the LED lamp beads.

[0062] FIG. 8 is the fifth schematic diagram of the under-display camera structure according to a preferred embodiment of the present application. As shown in FIG. 8, due to the converging effect of the convex glass 13, ambient light that could not originally be irradiated within the viewing angle of the front camera converges and enters the viewing angle of the front camera, increasing the amount of light incident on the front camera and contributing to further improvement of the imaging effect.

[0063] In this embodiment, a camera control device is further provided. This device is used to implement the above embodiments and preferred embodiments and will not be repeated here as it has already been described. As used below, the term "module" can implement a combination of software and / or hardware with a predetermined function. The devices described in the following embodiments are preferably implemented in software, but implementation in hardware or a combination of software and hardware is also possible and contemplated.

[0064] FIG. 9 is a block diagram showing the structure of a camera control device according to an embodiment of the present invention. As shown in FIG. 9, the device includes a first control module 92 configured to turn off a first type of lamp bead approaching the camera end that is predetermined when it is detected that the camera is in an on state, control a second type of lamp bead moving away from the camera to be in a lit state, and set the convex glass to a non-display state of the screen by forming a light ring on the convex glass after the light from the second type of lamp bead is refracted by the convex glass. A display is installed above the camera. The display includes the display glass and a display area backlight. An opening area is installed in the display area backlight above the camera. The display glass forms a convex glass presenting a convex shape in the direction of the camera at the opening area. A flexible circuit board presenting an annular conical structure is connected between the convex glass and the camera so as to surround the viewing angle of the camera.
