Description

Technical Field

[0001] The embodiments of the present invention relate to the field of smart terminals, and more specifically, to a camera control method and device, and an under-screen camera structure. Background Art

[0002] The term "full screen" literally means the entire front of the phone is screen, with all four sides of the phone adopting a borderless design, aiming for a screen-to-body ratio close to 100%. However, due to current technological limitations, only phones with ultra-high screen-to-body ratios exist, and no phone has achieved a 100% screen-to-body ratio on the front. Currently, what people refer to as a full-screen phone refers to a phone with a screen-to-body ratio of over 90% and an ultra-narrow bezel design.

[0003] All full-screen smartphone manufacturers must confront and address a common problem: the earpiece, front camera, and various sensors must be placed on the front of the phone, a daily user requirement. However, placing these components on the front of the phone inevitably takes up a portion of the display area. Currently, major smartphone manufacturers are seeking ways to reduce the area occupied by these functional components, resulting in the release of various full-screen smartphones, including the "notch screen," "waterdrop screen," and "hole-punch screen."

[0004] The related art proposes an under-screen camera, which includes: a display panel, a backlight module, a light guide component and a light source component. The backlight module is arranged on one side of the display panel, and a first opening is provided at a position corresponding to the under-screen camera. The light guide component is inserted into the first opening, and is used to guide the light beam entering the light guide component to the display panel area corresponding to the first opening. The light source component is used to provide a light source for the light guide component. When the under-screen camera is started, the light source component is turned off, and when the under-screen camera is not started, the light source component is turned on or off, so that the through hole or blind hole on the display panel can regain the display capability and still maintain the image quality that can be obtained by the under-screen camera.

[0005] The light source is provided by the side light guide component, which cannot adjust the light direction and focus. Most of the light cannot be directed upward into the glass area, affecting the backlight efficiency. At the same time, it cannot provide compensation light when the front camera is in use.

[0006] In the related art, the under-screen camera has a problem of limited light intake, resulting in poor shooting effects when the ambient light is weak. Summary of the Invention

In some instances, the memory 104 may further include a memory remotely located relative to the processor 102, and these remote memories may be connected to the mobile terminal via a network.

In one embodiment, the transmission device 106 may be a radio frequency (RF) module, which is used to communicate with the Internet wirelessly.

[0063] In this embodiment, a method for controlling an under-screen camera running on the above-mentioned mobile terminal or network architecture is provided. Figure 2 : is a flowchart of a method for controlling an under-screen camera according to an embodiment of the present invention. Figure 2 As shown, the process includes the following steps:

[0064] Step S202, when detecting that the camera is in the on state, turning off a predetermined first type of lamp bead close to the camera end, controlling a predetermined second type of lamp bead far from the camera to be in the lit state, and the light emitted by the second type of lamp bead is refracted through the convex glass to form a halo on the convex glass, so that the convex glass is in a non-displaying state, wherein a display screen is provided above the camera, the display screen includes the display glass and a display area backlight, the display area backlight above the camera is provided with an opening area, the display glass protrudes toward the camera direction in the opening area to form a convex glass, a flexible circuit board with an annular cone structure is connected between the convex glass and the camera to enclose the viewing angle of the camera, and a plurality of lamp beads are arranged on the flexible circuit board in sequence from the camera end to the convex glass end;

[0065] In an exemplary embodiment, the above step S202 may specifically include: turning off a predetermined first type of lamp beads close to the camera end according to a preset rule, and controlling a predetermined second type of lamp beads far from the camera to be in a lighting state.

[0066] Step S204, when it is detected that the camera is in the off state, the plurality of lamp beads are controlled to be in the lighting state, and the light is refracted through the convex glass to provide backlight for the convex glass, so that the convex glass is in the picture display state.

[0067] In an exemplary embodiment, the above step S204 may specifically include: controlling the brightness of the plurality of lamp beads through a backlight chip, wherein the flexible circuit board is used to conduct the plurality of lamp beads and is connected to the backlight chip.

[0068] Through the above steps S202 to S208, by setting a convex glass under the lower display glass and setting multiple lamp beads under the convex glass, the camera is set under the display glass. When the camera is turned off, the convex glass is a normal display glass. When the camera is turned on, some lamp beads and the display screen in the convex glass are turned off. The light emitted by the lamp beads away from the camera is refracted by the convex glass to form a halo on the convex glass, which provides fill light for the camera. This can solve the problem in the related art that the under-screen camera has limited light input, resulting in poor shooting effects when the ambient light is weak, and improve the shooting effect when the ambient light is weak.

[0069] In an exemplary embodiment, after controlling a predetermined second type of lamp bead far away from the camera to be in a lighting state, the second type of lamp bead is adjusted to a maximum brightness value.

[0070] In an exemplary embodiment, before turning off a predetermined first type of lamp bead close to the camera end and controlling a predetermined second type of lamp bead away from the camera to be in a lighting state, the inclination angle of the annular conical structure is determined, and further, the light entrance angle of the camera, the pixel of the camera, the brightness of the display screen, the thickness of the backlight of the display area, and the size of the opening area are obtained; the inclination angle of the annular conical structure is determined according to the light entrance angle of the camera, the pixel of the camera, the brightness of the display screen, the thickness of the backlight of the display area, and the size of the opening area;

[0071] The angle of light emitted by the lamp bead after being reflected by the convex glass is determined according to the inclination angle of the annular cone structure, the curvature of the convex glass, and the luminous angle of the lamp bead; the first type of lamp bead and the second type of lamp bead are determined according to the light angle, the luminous angle of the lamp bead, and the light incident angle of the camera.

[0072] In another exemplary embodiment, after determining the inclination angle of the annular cone structure, the number of the multiple lamp beads and the arrangement of the multiple lamp beads are determined according to the brightness of the display screen, the inclination angle of the annular cone structure, and the size of the opening area.

[0073] Through the description of the above embodiments, those skilled in the art can clearly understand that the method according to the above embodiment can be implemented by means of software plus the necessary general hardware platform, and of course it can also be implemented by hardware, but in many cases the former is a better implementation method. Based on this understanding, the technical solution of the present invention is essentially or the part that contributes to the prior art can be embodied in the form of a software product, which is stored in a storage medium (such as ROM / RAM, magnetic disk, optical disk), and includes a number of instructions for enabling a terminal device (which can be a mobile phone, computer, server, or network device, etc.) to execute the methods described in each embodiment of the present invention.

[0074] This embodiment also provides a camera structure under the display screen. Figure 3 Schematic diagram of the under-screen camera structure according to an embodiment of the present application. Figure 3As shown, it includes: a display screen 1 and a camera 2 arranged under the display screen, the display screen 1 includes a display glass 11 and a display area backlight 12, wherein the display area backlight above the camera 2 is provided with an opening area, the display glass 11 protrudes toward the camera 2 in the opening area to form a convex glass 13, a flexible circuit board 3 with an annular cone structure is connected between the convex glass 13 and the camera 22 to enclose the viewing angle of the camera 2, and a plurality of lamp beads are arranged on the flexible circuit board 3 in sequence from the camera 2 end to the convex glass end, wherein,

[0075] When the camera 2 is turned on, the lamp beads near the camera 2 among the multiple lamp beads are turned off, and the lamp beads away from the camera 2 are turned on. The light emitted by the lamp beads away from the camera 2 is refracted by the convex glass 13 to form a halo on the convex glass 13, so that the convex glass 13 is in a state where the image is not displayed;

[0076] When the camera 2 is in the off state, the multiple lamp beads are all in the lighted state, and provide backlight for the convex glass 13 after being refracted by the convex glass 13, so that the convex glass 13 is in the picture display state.

[0077] In an exemplary embodiment, the lamp beads far away from the camera 2 are at a maximum brightness.

[0078] In an exemplary embodiment, the angle of the annular cone structure of the flexible circuit board 3 is determined according to the viewing angle of the camera 2, the pixels of the camera 2, the brightness of the display screen, the thickness of the display area backlight, and the size of the opening area.

[0079] In another exemplary embodiment, the flexible circuit board 3 is used to conduct the multiple lamp beads and is connected to a backlight chip, wherein the backlight chip is used to control the brightness of the multiple lamp beads.

[0080] 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 a viewing angle 301; the normal display area backlight 12 can use the existing backlight structure solution, which will not be described in detail; the front camera area backlight 4 is divided into multiple small LED lamp beads and a flexible circuit board 3. The flexible circuit board 3 connects and conducts the multiple LED lamp beads, and can independently control the brightness of each lamp bead through the backlight chip. The front camera area backlight 4 has an annular cone structure as a whole, and the central opening avoids the viewing angle of the front camera 2.

[0081] Figure 4 This is a schematic diagram of the under-screen camera structure according to the preferred embodiment of this application Figure 1 ,like Figure 4 As shown, when the front camera is not in use and full-screen display is required, the LED lamp beads emit light to provide backlight for the front camera area display glass. Each LED lamp bead has a certain illumination angle, which can completely cover the entire front camera area display glass. The backlight chip adjusts the brightness of each LED lamp bead, which can make the backlight of the entire front camera area display glass uniform without adding additional light-scattering or light-guiding materials. The light emitted by the LED lamp beads passes through the converging effect of the convex glass 13 in the front camera area and is concentrated upward to emit from the screen, achieving a better display effect.

[0082] Figure 5 This is a schematic diagram of the under-screen camera structure according to the preferred embodiment of this application Figure 2 ,like Figure 5 As shown, when the front camera needs to be used, if all the LED lamp beads are still on, part of the light emitted by the LED lamp beads close to the front camera will be reflected by the convex glass 13 and enter the front camera's field of view, interfering with the front camera's imaging.

[0083] Figure 6 This is a schematic diagram of the under-screen camera structure according to the preferred embodiment of this application Figure 3 ,like Figure 6 As shown, when the front camera is in use, only the portion of the LED lamp beads away from the front camera is turned on to ensure that the light emitted by the LED lamp beads does not reflect into the front camera's field of view. The turned-on LED lamp beads are adjusted to maximum brightness. At this time, the convex glass 13 does not display the image, but instead forms a halo. Most of the images taken using the front camera are close-up people and scenery. The light emitted by the halo shines on the close-up people and scenery and then reflects back, which can increase the amount of light entering the front camera 2 and improve the imaging effect.

[0084] Figure 7 This is a schematic diagram of the under-screen camera structure according to the preferred embodiment of this application Figure 4 ,like Figure 7 As shown in the figure, determining which LEDs will light up when the front camera is turned on requires a combination of 3D simulation and darkroom debugging. This is primarily dependent on the following factors: the tilt angle a of the flexible circuit board, the curvature b of the convex glass, the emission angle c of the LEDs, the light incident angle d of the front camera, the angle e of the light reflected by the convex glass, the horizontal distance f from the edge of the backlight aperture to the center of the front camera, the distance g from the LED to the edge of the flexible circuit board, and the horizontal distance h from the LED to the center of the front camera.

[0085] The two most important factors in 3D simulation are the angle e of the light emitted by the lamp after it is reflected by the convex glass and the horizontal distance h from the lamp to the center of the front camera. The smaller the angle e, the less likely the light will enter the front camera, and the larger the horizontal distance h, the less likely the light will enter the front camera.

[0086] according to Figure 7 The relationship between the marked dimensions can be calculated as follows: e = 90° - a + (c / 2) - 2b, h = fg * sin(a). This formula shows that, within a certain range, the larger the angles a and b, the smaller the angle e; the smaller the angle c, the smaller the angle e. Within a certain range, the larger the distance f, the larger the distance h; and the smaller the distance g and angle a, the larger the distance h. The specific dimensions and angles must be carefully considered when designing to avoid issues such as the flexible circuit board obstructing the front camera's view and overly large backlight openings exposing the edge of the front camera.

[0087] In actual application, 3D simulation calculations are first performed to obtain a preliminary LED lamp bead design plan. To finally confirm which LED lamp beads can be turned on when using the front camera, detailed debugging is required in a dark box. The entire machine is placed in the dark box, and some of the lamp beads that can be lit according to the 3D simulation calculations are turned on. At the same time, the front camera is turned on. If the front camera's photosensitive device can sense light, it is necessary to turn off the row of lamp beads close to the front camera until the front camera's photosensitive device can no longer sense the light reflected by the LED lamp beads.

[0088] Figure 8 This is a schematic diagram of the under-screen camera structure according to the preferred embodiment of this application Figure 5 ,like Figure 8 As shown, the converging effect of the convex glass 13 can also converge the ambient light that originally could not enter the front camera angle and enter the front camera angle, thereby increasing the amount of light entering the front camera and further improving the imaging effect.

[0089] This embodiment also provides a camera control device for implementing the above-mentioned embodiments and preferred implementations. Details already described will not be repeated. As used below, the term "module" may refer to a combination of software and / or hardware that implements a predetermined function. Although the devices described in the following embodiments are preferably implemented in software, implementation in hardware, or a combination of software and hardware, is also possible and contemplated.
