For the convenience of understanding the structure for hiding the front camera provided by the embodiment of the present invention, an application scenario thereof is first described below. The structure for hiding the front camera is applied to terminal equipment, and the terminal equipment can be common terminal equipment such as a tablet personal computer and a mobile phone. As shown in fig. 1, the terminal device includes a display screen, and a cover glass stacked on the display screen, where the cover glass is located on a light emitting surface of the display screen. In addition, the terminal equipment further comprises a front camera which is hidden, so that when the display screen is arranged, a gap or a through hole is formed in the corresponding area of the display screen above the front camera. Of course, in the description of fig. 1, the front camera is taken as an example, and the structure corresponding to the notch or the through hole may also be other devices, such as a proximity optical sensor, a color light source, and the like. In addition, the terminal device provided in the embodiment of the present application further includes a processor, and the processor is configured to control the operation of the front-facing camera, the display screen, and the like.
With continued reference to fig. 1, the structure provided by the embodiment of the present application includes a light guide plate 20, and the light guide plate 20 is located between the front camera and the cover glass when assembled on the terminal device, and may be located above the display screen or below the display screen with respect to the display screen, but whichever side of the display screen is located, the projection of the light guide plate 20 on a plane perpendicular to the display screen covers the projection of the notch on the plane, so that the notch or the through hole can be covered by the light guide plate 20. In addition, the structure further includes one or more color light sources, the color light sources are located at the side of the light guide plate 20 and used for emitting light of a specified color to the side of the light guide plate 20 under the control of the processor, and after the light is transmitted into the light guide plate 20, the light guide plate 20 is used for changing the propagation direction of the light of the specified color to a direction perpendicular to the display screen, so that the light guide plate 20 displays the specified color, and the notch or the through hole corresponding to the front camera is shielded by the light.
With continuing reference to fig. 1, with the placement direction of the structure shown in fig. 1 as a reference direction, when three components are provided, the light guide plate 20 is disposed in a stacked manner with the camera 10 and above the camera 10, and the color light source 30 is disposed on at least one side of the light guide plate 20.
With reference to fig. 1, when the light guide plate 20 provided by the embodiment of the present invention is disposed, the shape thereof may be different shapes, such as different shapes like a circle, a polygon, an ellipse or an irregular shape, and when the light guide plate is disposed specifically, different shapes may be selected according to actual needs. The light guide plate 20 is located in the viewing angle area of the camera 10; so that light irradiated from an object imaged by the camera 10 needs to enter the range of the camera 10 through the light guide plate 20. In the structure shown in fig. 1, the light guide plate 20 is rectangular, and for convenience of describing the light guide plate 20, each surface of the light guide plate 20 is defined, a surface of the light guide plate 20 away from the camera 10 is a first surface, a surface of the light guide plate 20 facing the camera 10 is a second surface, and surfaces connected to the first surface and the second surface are side surfaces. With reference to fig. 1, the light guide plate 20 is a plate-shaped structure, wherein the length and width of the light guide plate 20 are much greater than the thickness of the light guide plate 20, wherein the length and width of the light guide plate 20 refer to the length and width of the first surface of the light guide plate 20, and the thickness of the light guide plate 20 refers to the vertical distance from the first surface to the second surface. When in use, as shown in fig. 1, the light guide plate 20 is parallel or approximately parallel to the light emitting surface of the lens of the camera 10; external light enters from the first surface, passes through the light guide plate 20, and exits from the second surface to enter the camera 10. The light guide plate 20 is also used for scattering the light emitted from the color light source 30 to the first surface. Therefore, in the setting process, in order to improve the scattering effect, when the light guide plate 20 is specifically set, the light guide plate 20 is a nano light guide plate 20, and the light guide plate 20 is made of transparent plastic or glass doped with nano-scale small particles, that is, the nano particles 21 are set in the prepared light guide plate 20, and the nano particles 21 are doped in the light guide plate 20 to improve the light scattering effect, when the nano particles 21 are specifically doped, the concentration common in the prior art can be adopted for doping, and the size of the nano particles 21 can be selected according to specific needs. Such as nanoparticles 21 having a diameter of 1um or less.
In addition, the light guide plate 20 in the embodiments of the present invention includes, but is not limited to, a light guide plate 20 or a film doped with nanoparticles, and a light guide plate 20 or a film printed with microstructures (e.g., dots, lines). The light guide plate 20 may be an electrically controlled liquid crystal panel or an electrically controlled liquid crystal film. The electrically controlled liquid crystal panel or the electrically controlled liquid crystal film is a transparent light guide plate 20 when being powered on, and becomes foggy when not being powered on, and the shielding of the through hole or the notch can be realized through the electrically controlled liquid crystal panel or the electrically controlled liquid crystal film.
When the light guide plate 20 is disposed, the light guide plate 20 may be located above the display screen or below the display screen, and the specific disposition position may be determined according to the space in the actual terminal device. In a specific arrangement, when the light guide plate 20 is located above the display screen, the light guide plate 20 may be embedded in the cover glass, and the lower surface of the light guide plate 20 is flush with the lower surface of the cover glass, so that the light guide plate 20 may be fixed by the cover glass, of course, the embedding of the light guide plate 20 in the cover glass is only a specific embodiment, and the light guide plate 20 provided in the embodiment of the present application may also be fixed in other manners.
In addition, the light guide plate 20 is coated with a light attenuating material, such as black paint or other color paint, on the sides of the periphery (sidewalls) except for the side opposite to the color light sources. When light irradiates the light guide plate 20, the light attenuation material can effectively reduce the leakage of the light from the side wall of the light guide plate 20, and improve the matching effect of the light guide plate 20 and a display screen when in use.
When specifically arranging the color light sources 30, the number of the color light sources 30 may be different, such as one, two, three, four, etc., and when specifically arranging, the color light sources 30 are arranged on at least one side of the light guide plate 20. When the light guide plate 20 has a rectangular shape, the color light sources 30 may be disposed on one side surface, or two adjacent side surfaces, three side surfaces, or four side surfaces of the light guide plate 20; when the light guide plate 20 has an oval or circular shape, the color light sources 30 may be disposed on a side surface of a segment, or the color light sources 30 may be disposed on the entire circumference. The number of the color light sources 30 provided on each side of the light guide plate 20 may be one or more. And when the color light source 30 is disposed, the light emitting surface of the color light source 30 faces the light guide plate 20, so that the light emitted from the color light source 30 can be irradiated into the light guide plate 20, as shown by the dotted arrow in fig. 1, the light emitted from the color light source 30 can be diffused by the nanoparticles 21 to be scattered out of the first surface, thereby improving the uniformity of the light irradiated out of the first surface.
In addition, when the color light source 30 is specifically arranged, the color light source 30 can emit light rays with different colors, so that the colors of the light guide plate 20 and the display screen 200 can be matched as much as possible when displaying. For example, each of the color light sources 30 includes red, green, and blue light emitting diodes (RGB LEDs), so that the color light sources 30 can emit light beams with different colors, and when in use, different color light sources 30 can be controlled to emit different light beams according to requirements, for example, some of the color light sources 30 emit red light beams, another part of the color light sources 30 emit blue light beams, and other color light sources 30 emit green light beams. The determination of the different light emissions of the colored light sources 30 is controlled by a processor in the terminal device. When the processor controls the color light source 30 to emit a specific color, the specific color is the color corresponding to the image data in the display buffer corresponding to the notch, which can be understood as the color that should be displayed when the notch is not set on the display screen. Or the designated color is similar to or the same color as the color of the display screen around the notch. Therefore, the color displayed by the light guide plate 20 is approximately the same as the color displayed by the display screen, the display difference between the light guide plate 20 and the display screen is reduced, and the display effect of the display screen is improved.
When the color light sources 30 are provided, the color light sources 30 emit light in a side direction, and the light emitted from the color light sources 30 is directly emitted to the light guide plate 20. In order to match the color light source 30 with the light guide plate 20, when the color light source 30 is disposed, the thickness of the color light source 30 is the same as that of the light guide plate 20, and the color light source is flush with the side surface of the light guide plate 20 when disposed, that is, the light emitting surface of the color light source 30 is flush with the side surface of the light guide plate 20, so that the light emitted by the color light source 30 can be transmitted into the light guide plate 20 more uniformly, and the light transmission effect is improved.
This light guide plate 20 can be used for letting external light pass through and get into leading camera at leading camera during operation, and at this moment, external light can directly pass light guide plate 20 back shine leading camera on, leading camera can normally work. Further, the light guide plate 20 displays light of a designated color when the front camera is not operated. At this time, the color light source emits light of a designated color to the light guide plate 20, and the light guide plate 20 reflects the designated color to the light emitting surface, so that the light guide plate 20 displays a color similar to that of the display screen.
The embodiment of the present invention provides a camera module to improve the display effect of the terminal device 100. The following describes the application of the camera module in detail with reference to the accompanying drawings.
For convenience of understanding, the structure of the terminal device 100 provided in the embodiment of the present invention is explained first, where the terminal device 100 includes the display screen 200 and any one of the structures described above; in a specific arrangement, a light-transmitting region (the above-mentioned notch or through hole) corresponding to the camera 10 is provided on the display screen 200, and the light guide plate 20 covers the light-transmitting region. The light-transmitting regions may have different structures, which will be described below by way of example.
As shown in fig. 2, the light-transmitting area is a notch 201 provided on the display screen 200. At this time, when the terminal device 100 is set, it adopts a configuration of setting an external sensing device, or a structure, a protrusion protruding toward the display screen 200 is provided on the frame of the terminal device 100, and the protrusion is used to accommodate the camera 10 and the sensor, etc. to be set. When the display screen 200 is arranged, a notch 201 is correspondingly arranged on the display screen 200. The notch 201 may be disposed at a middle position of one edge of the display screen 200, or at other positions, depending on the position of the protrusion, and is generally disposed at the middle position. In the embodiment of the present invention, the structure is disposed at the position of the protrusion, i.e. at the position of the notch 201. Referring to fig. 3 together, fig. 3 shows a specific arrangement of the structure in the embodiment of the present invention. In a specific arrangement, as shown in fig. 1, the light guide plate 20 covers the notch 201, and when the notch 201 is specifically covered, two different manners may be adopted, one being that the light guide plate 20 is located inside the notch 201 and embedded in the notch 201. In another way, the light guide plate 20 is stacked on the display panel 200, and the light guide plate 20 partially covers the non-display area of the display panel 200, which is the non-display area around the notch 201, and it can refer to the structure shown in fig. 3 that the partial area of the light guide plate 20 covers the non-display area of the display panel 200 around the notch 201. And when the color light sources 30 are provided, as shown in fig. 3, a plurality of color light sources 30 are provided on the side of the light guide plate 20 opposite to the display screen 200. When light compensation is required, light emitted from the color light source 30 enters the light guide plate 20 and is emitted from the first surface of the light guide plate 20. Thereby enabling the light guide plate 20 to display different colors. Further, since the light guide plate 20 and the display panel 200 are stacked and the color light sources 30 are located on the side opposite to the display panel 200, the light guide plate 20 can emit light in any region in contact with the non-display region of the display panel 200, and at this time, the non-display region of the display panel 200 can be shielded so that the display region of the display panel 200 and the light emitting region of the light guide plate 20 can be maximally approached. When the display is observed from the outside, the light emitted from the light guide plate 20 can make up the notch 201 of the display 200, so that the picture display is more complete.
With continued reference to fig. 3, when the light guide plate 20 is specifically disposed, the light guide plate 20 may be connected to the display panel 200 by adhesion, and of course, the light guide plate 20 may be connected to the display panel 200 by other methods. Or the light guide plate 20 is fixedly connected with the middle frame of the terminal device 100, and the laminated part of the light guide plate 20 and the display screen 200 is suspended, so that the relative fixation between the light guide plate 20 and the display screen 200 can also be realized. And when the light guide plate 20 is specifically disposed, the light guide plate 20 is located at a side of the display surface of the display panel 200, so that the light emitted from the light guide plate 20 can shield the non-display area of the display panel 200. For the arrangement position of the camera 10, the camera and the light guide plate 20 are arranged on two sides of the display screen 200 respectively, so that the opening size of the notch 201 is reduced, and the influence on the display screen 200 is reduced to the maximum extent.
When the structure is specifically configured, as shown in fig. 3, a layer of glass cover 300 is further disposed on the terminal device 100, and the glass cover 300 covers the display panel 200 and the light guide plate 20, so as to protect the light guide plate 20 and the display panel 200.
Further, in specifically setting the configuration, when the configuration is applied to the terminal device 100, it is connected with a processor of the terminal device. When the method is applied, when the processor acquires a complete image data, the processor intercepts the image content data at the bulge, carries out processing such as averaging and the like, and acquires a monochromatic RGB numerical value (in a user interface of an android system, most scenes at the bulge are monochromatic). Then, while sending the display to the display screen 200, the monochrome RGB value is sent to the processor, so that the color light source 30 is controlled to be lighted while the screen is displaying, thereby obtaining the complete display of the whole screen and improving the display effect of the whole terminal device 100.
It should be understood that the light guide plate 20 in the camera module provided by the embodiment of the present invention is not limited to the camera 10 shown in fig. 3, and it can also be used to shield other sensing devices, only needs the light guide plate 20 to be able to transmit the light corresponding to the sensing device. The principle is similar to that of the shielding camera 10, and will not be described herein.
