The foregoing is a core idea of the present invention, and in order that the above-mentioned objects, features and advantages of the present invention can be more readily understood, a technical solution in an embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings in an embodiment of the present invention, and it is obvious that the described embodiment is only a part of embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The display device with the 3D camera module provided by the embodiment of the invention, as shown in fig. 1, comprises a display panel 10 and a 3D camera module, wherein the display panel 30 is provided with a light emitting area and a light entering area penetrating along the thickness direction, and the 3D camera module comprises a depth camera module positioned on the backlight side of the display panel 10. It should be noted that, in an embodiment of the present invention, the depth camera module is an infrared camera module, and the laser is an infrared laser that emits infrared laser.
The light-emitting side of the display panel is a side capable of displaying an image, and the backlight side is a side incapable of displaying an image. That is, the depth camera module in an embodiment of the present invention may be located below the display panel 10, i.e. may be disposed below the screen, and no hole is required to be dug in the non-display area on the top of the display panel 10 to dispose the depth camera module.
In one embodiment of the present invention, the depth camera module includes a laser 11 and an imaging module 12. The laser 11 and the imaging module 12 are both located at the backlight side of the display panel 10, and the light outlet of the laser 11 is disposed towards the display panel 10, so that laser light can pass through the light outlet area on the display panel 10 and irradiate onto an object to be photographed located at the light outlet side of the display panel 10, and the light inlet of the imaging module 12 is disposed towards the display panel 10, so that laser light reflected by the object to be photographed passes through the light inlet area on the display panel 10 and then enters the imaging module 12.
In an embodiment of the present invention, the light emitting area and the light entering area adopt a light transmitting structure with any one of the following shapes:
-a single through hole;
-a matrix of through holes formed of a plurality of through holes, as shown in fig. 7 (a), 7 (b), 7 (c);
-a light-transmitting structure formed by a plurality of communicating through holes
-A single light transmission channel;
-a light-transmitting structure formed by a plurality of communicating light-transmitting channels, as shown in fig. 8 (a);
The through holes and the transmission channels are in communication to form a light-transmitting structure, as shown in fig. 8 (b).
In one embodiment of the present invention, the cross-sectional diameter of the single through hole is smaller than 2mm. In a preferred embodiment of the invention, the individual through holes have a cross-sectional diameter of 1mm.
Fig. 2 is a schematic structural diagram of a display device according to a modification of the present invention, as shown in fig. 2, the extending directions of the light emitting area and the light entering area are perpendicular to a side surface of the display panel 10.
In a preferred embodiment of the present invention, the single through hole extends at an angle of 30 °, 45 ° or 60 ° to one side of the display panel 10.
In an embodiment of the present invention, a reflective layer is plated on the inner wall surfaces of the light emitting area and the light entering area, so as to implement total reflection of the laser on the inner wall surfaces of the light emitting area and the light entering area. Such as a metal layer or a highly reflective coating. The metal may be aluminum, silver, gold, copper, or another highly reflective metal.
The imaging module 12 is used for receiving the laser light reflected by the object to be shot and passing through the display panel 10, and obtaining a depth image of the surface of the object to be shot according to the laser light, wherein the depth image comprises depth information of different areas of the surface of the object to be shot.
In addition, since the laser 11 and the imaging module 12 are both disposed on the backlight side of the display panel 10, the arrangement and combination of the laser 11 and the imaging module 12 have multiple possibilities, and the distance between the laser 11 and the imaging module 12 can be increased on the premise of not affecting the beauty, so as to improve the shooting precision of the depth camera module.
Optionally, as shown in fig. 3, the depth camera module further includes a beam splitter 13 between the display panel 10 and the laser 11, where the beam splitter 13 is configured to split the laser light emitted by the laser 11 into multiple laser lights that are randomly distributed.
In an embodiment of the present invention, as shown in fig. 1,2 and 3, the depth camera module includes a driving circuit 14 connected to the laser 11 and the imaging module 12. The driving circuit 14 is used to control the laser 11 and the imaging module 12 to be turned on or off simultaneously, and to control the output optical power of the laser 11 by controlling the driving current of the laser 11, so as to control the optical power of the laser light passing through the display panel 10 by controlling the output optical power of the laser 11.
Further, the depth camera module further comprises a processing module 15,3D and a 2D imaging module. The 2D imaging module is used for shooting a 2D image of an object to be shot. The processing module 15 is configured to obtain a 3D image of the object to be photographed according to the depth image photographed by the 3D photographing module and the 2D image photographed by the 2D imaging module.
It should be noted that, if the depth camera module is disposed below the screen, i.e., on the backlight side of the display panel 10, in order to obtain an image of an object to be photographed (for example, a human face) above the screen, i.e., on the light emitting side of the display panel 10, the laser light emitted from the depth camera module must pass through the display panel 10, be reflected by the object to be photographed, pass through the display panel 10 again, and be received by the imaging module 12.
Since the transmittance of the display panel 10 to laser light is very low, the transmittance of the OLED display panel 10 to infrared laser light is generally less than 5%, and even if the transmittance of the OLED display panel 10 to infrared laser light is specially designed and processed, the total transmittance after passing through the screen twice is only 30% by 30% = 9%, so that the output light power of the existing VCSEL laser must be increased by more than 10 times to enable the depth camera module to work normally. It is therefore necessary to make light outgoing and incoming areas in the display panel 10 for outgoing and incoming of the laser light.
In order to set the depth image capturing module on the backlight side of the display panel 10, the driving circuit 14 may increase the driving current, reduce the pulse width of the laser 11, greatly increase the optical power of the laser 11, and simultaneously keep the total pulse energy of the laser 11 substantially unchanged, so as to satisfy the optical power limitation of eye safety.
In one embodiment of the present invention, as shown in fig. 4, an optical lens 16 is further disposed between the beam splitter 13 and the display panel 10, and the optical lens 16 is used for collimating the laser light and irradiating the collimated laser light onto the display panel 10. The imaging module 12 is a first imaging module, optionally an infrared camera. The first imaging module obtains a depth image of the surface of the object to be shot according to the received light spot pattern of the laser reflected by the object to be shot.
Specifically, the beam splitter 13 splits the laser beam emitted by the laser 11 into a plurality of randomly distributed lasers, when the lasers are irradiated on a plane, a light spot image as shown in fig. 5 is formed, when the plurality of lasers are irradiated on an object to be photographed, the light spot pattern deforms or shifts, after the first imaging module photographs the light spot pattern on the surface of the object to be photographed, a depth image of the surface of the object to be photographed is obtained according to the deformation or shift of the light spot pattern, and then the rugged depth information of the surface of the object to be photographed is obtained. The processing module 15 can obtain a 3D image of the object to be photographed according to the depth image and the 2D image.
In another embodiment of the present invention, as shown in fig. 6, a diffuser 17 is further disposed between the light splitting device 13 and the display panel 10, and the diffuser 17 is used for diffusing the laser emitted from the light splitting device 13 to flood the laser onto the display panel 10. The imaging module is a second imaging module, optionally a TOF (Time of Flight) camera. And the second imaging module obtains a depth image of the surface of the object to be shot according to the received time delay or phase difference of the laser reflected by the object to be shot. That is, the second imaging module obtains a depth image of the surface of the object to be photographed according to a time difference between the time of emitting the laser light and the time of receiving the laser light, or according to a phase difference between the emitted laser light and the received laser light. Then, the processing module 15 can obtain a 3D image of the object to be photographed according to the depth image and the 2D image.
In an embodiment of the present invention, the light-splitting device 13 may be a nanophotonic chip, a diffraction grating (DIFFRACTIVE OPTICS ELEMENT, DOE), a coded structure photomask, or the like, which is not limited thereto.
According to the display device with the 3D camera module, the output light power of the laser is high, and even when the display panel with low transmissivity is faced, the light power of the laser passing through the display panel is high, so that the depth camera module can be arranged on the backlight side of the display panel, a non-display area is not required to be arranged in the top area of the display device for installing the depth camera module, and the attractiveness and the overall screen experience of the display device are not affected.
In addition, the laser 11 in one embodiment of the invention adopts an edge emitting laser (EDGE EMITTING LASER, EEL for short), so that the depth image can be shot by adopting only one laser 11, the cost is lower, in addition, the 3D camera module provided by the embodiment of the invention can also be produced in large scale because the laser 11 can be produced in large scale, and in addition, the heat resistance of the substrate of (EDGE EMITTING LASER, EEL for short) is much smaller than that of the VCSEL laser, so that the heat dissipation performance of the laser 11 and the 3D camera module is better.
In one embodiment of the invention, laser 11 may also employ a vertical cavity Surface emitting laser array (VERTICAL CAVITY Surface EMITTING LASER, VCSEL) as the light source.
The embodiment of the invention also provides electronic equipment which comprises the display device provided by any embodiment, and the electronic equipment can be a mobile phone, a tablet personal computer, a digital camera and the like. According to the electronic equipment with the 3D camera module, a non-display area is not required to be arranged in the top area of the display device to install the depth camera module, so that the appearance is more attractive, and the comprehensive screen experience is realized more conveniently.
In the present specification, each embodiment is described in a progressive manner, and each embodiment is mainly described in a different point from other embodiments, and identical and similar parts between the embodiments are all enough to refer to each other. The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention.
